Subject: [PATCH 02/32] Bug#35158675 Compile MySQL 5.7 with gcc 12

Compiling MySQL 5.7 with gcc 12, we need to backport some cmake code:
Disable -Wunused-label when compiling the generated BISON parsers.

Note that 5.7 is not officially supported for gcc 12,
this is just for developer convenience.

Subject: [PATCH 05/32] Bug#34741689: mysqld crash at
 row_upd_sec_index_entry_low

row_upd_store_v_row() might call handler::my_eval_gcolumn_expr().
But it might overwrite new_row buffer from mysqld
and v_col's node->update->fields[*].new_val.data contents might be changed.

So, before calls handler::my_eval_gcolumn_expr(),
v_col's node->update->fields[*].new_val should be duplicated.

In addition, 8.0 code needs to treat also multi value fields.
Treating with the duplicate code as same as just before this fix.

Subject: [PATCH 06/32] Bug#32824429 - SIGNAL 11 / VIRTUAL LONGLONG
 ITEM_FUNC_IN::VAL_INT(): 		ASSERTION `IN_ITEM'

Problem:
	Floating point literal in query was identified as real number,
	then converted to zerofilled string to compare with
	zerofilled float column.
	Due to being identified as a real number the comparison was
	attempted in a real context, even after the value was converted
	to string.
Solution:
	Convert zerofill numbers to zerofilled Item_string only when
	used in a string context, eg. concat or comparing with a string
	constant.

Subject: [PATCH 07/32] Bug#34976442 mysqld crashed

Problem
====================

On an MySQL Innodb cluster deployment which has:
- A virtualization platform of Docker/Kuberenetes;
- 3 nodes working and running

During regular operation, one of the nodes crashes and it is was unable
to start and join the group again. In order to restore the system,
the whole group was restarted and then all members crashed in
get_ipv4_local_addresses within GCS/XCom.

Analysis and Fix
====================

Docker/Kuberenetes create a lot of network interfaces within a pod,
for a virtual network. In this specific case, more than 64 interfaces.

What happened was that XCom allocates an array of 64 interfaces which
is reallocated each time we overflow it. Specifically,
`ifrp` is overflowed when network interface is more than
IFRP_INIT_ARR_SIZE(64). But it is not reallocated because wrong
condition `i==ifrpsize`.

The solution is to fix the wrong reallocate condition.

Subject: [PATCH 10/32] Bug#34758905 Range analysis for IN list has O(n^2)
 runtime complexity

During optimization, range SEL_TREE creation uses different logic
based on the LHS of the IN predicate. For a field item, each RHS
value is added to an OR tree to create the necessary expression. In
the case of a row item comparison, a DNF expression is needed. A DNF
expression is created by adding an AND tree with column values to an
OR  tree for each set of RHS values. Instead of adding each new AND
tree to the OR tree, the OR tree is added to the AND tree causing
exponential time during the tree merge.

Solution: Change the tree joining the order. Instead of adding OR
tree to the AND tree, add AND tree to the OR tree.

Subject: [PATCH 15/32] Bug #23036096 - INNODB LAST DETECTED DEADLOCK NOT
 SHOWING FULL QUERY

The last detected deadlock section of the engine status log is only showing
1024 characters (combined) of the thread information and the query.

Fixing the issue by removing the limit on printing the query string.
Reasons for this fix:
1. The thd_security_context() expects the user to give a sufficently
large bufffer to write.
2. It is difficult to guess the right size of the buffer without
creating a dependency on internal format of the message created by
thd_security_context.
3. Refactoring thd_security_context is not a good idea as it seems to
be a part of plugin's API spec, instead we are just truncating the
message created by thd_security_context.
4. Instead of trimming the query, we set the length of the buffer to
max_query_len + 1 KB (so as to hold any additional information)

Subject: [PATCH 17/32] Bug#34900334: Bug that can make MySQL fail

If order by references a subquery in select list through
an alias, and if the query block having the order by gets
merged, then while deleting the unused merged derived
columns, the subquery gets deleted.
This is not correct as it is still being used in order by.
To determine if a merged derived column is used or not,
"derived_used" is checked. "derived_used" is not set for
this case because resolving for order by does not make a
call to fix_fields() when it is resolved against alias in
the select list.
Solution is to set derived_used for the order by
expression when merging the derived table's order by into
the outer query block.

Subject: [PATCH 21/32] Bug#35432973 InnoDB: processing single character tokens
 with FTS parser plugin

In scenarios where FTS parsing plugin (like ngram) is used with single-character tokens,
incorrect behavior occurs due to the fact that fts_tokenize_ctx_t::processed_len has
double meaning: normally for built-in parser it indicates how much of the document has
been processed, but when parser plugin was used and the document was not completely
processed, a non-zero value (which in practice was 1) would indicate that tokenization
by the plugin was complete. However the surrounding code did not take into account
this change of semantics - this is amended.

Patch based on contribution by Shaohua Wang

Subject: [PATCH 22/32] Bug#34704094 - Mysql str_to_date can correct convert
 for '2022-11-30'

Issue:
STR_TO_DATE function doesn't validate the date as whole, it takes
date like '2022-11-31' as a valid datetime.

Analysis:
When we check date time value for validity, we need to check if the
day mentioned in the query is not greater than total number of days
for the given month. This check was missing because of which invalid
date like '2022-02-31' was getting considered as correct.

Fix:
Fixed the issue by providing above mentioned check.

+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002 Free Software
+Foundation, Inc.
+
+   This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory.  After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the `--target=TYPE' option to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+will cause the specified gcc to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+\`configure' configures libedit 3.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
+  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]

+                          compiler's sysroot if not specified).
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  LT_SYS_LIBRARY_PATH
+              User-defined run-time library search path.
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH

+.Sh DESCRIPTION
+The
+.Nm
+library provides generic line editing, history and tokenization functions,
+similar to those found in
+.Xr sh 1 .
+.Pp
+These functions are available in the
+.Nm libedit
+library (which needs the
+.Nm libtermcap
+library).
+Programs should be linked with
+.Fl ledit ltermcap .
+.Pp
+The
+.Nm
+library respects the
+.Ev LC_CTYPE
+locale set by the application program and never uses
+.Xr setlocale 3
+to change the locale.
+.Sh LINE EDITING FUNCTIONS
+The line editing functions use a common data structure,
+.Fa EditLine ,
+which is created by
+.Fn el_init
+or
+.Fn el_init_fd
+and freed by
+.Fn el_end .
+.Pp
+The wide-character functions behave the same way as their narrow
+counterparts.
+.Pp
+The following functions are available:
+.Bl -tag -width 4n
+.It Fn el_init
+Initialize the line editor, and return a data structure
+to be used by all other line editing functions, or
+.Dv NULL
+on failure.
+.Fa prog
+is the name of the invoking program, used when reading the
+.Xr editrc 5
+file to determine which settings to use.
+.Fa fin ,
+.Fa fout
+and
+.Fa ferr
+are the input, output, and error streams (respectively) to use.
+In this documentation, references to
+.Dq the tty
+are actually to this input/output stream combination.
+.It Fn el_init_fd
+Like
+.Fn el_init
+but allows specifying file descriptors for the
+.Xr stdio 3
+corresponding streams, in case those were created with
+.Xr funopen 3 .
+.It Fn el_end
+Clean up and finish with
+.Fa e ,
+assumed to have been created with
+.Fn el_init
+or
+.Fn el_init_fd .
+.It Fn el_reset
+Reset the tty and the parser.
+This should be called after an error which may have upset the tty's
+state.
+.It Fn el_gets
+Read a line from the tty.
+.Fa count
+is modified to contain the number of characters read.
+Returns the line read if successful, or
+.Dv NULL
+if no characters were read or if an error occurred.
+If an error occurred,
+.Fa count
+is set to \-1 and
+.Dv errno
+contains the error code that caused it.
+The return value may not remain valid across calls to
+.Fn el_gets
+and must be copied if the data is to be retained.
+.It Fn el_wgetc
+Read a wide character from the tty, respecting the current locale,
+or from the input queue described in
+.Xr editline 7
+if that is not empty, and store it in
+.Fa wc .
+If an invalid or incomplete character is found, it is discarded,
+.Va errno
+is set to
+.Er EILSEQ ,
+and the next character is read and stored in
+.Fa wc .
+Returns 1 if a valid character was read, 0 on end of file, or \-1 on
+.Xr read 2
+failure.
+In the latter case,
+.Va errno
+is set to indicate the error.
+.It Fn el_getc
+Read a wide character as described for
+.Fn el_wgetc
+and return 0 on end of file or \-1 on failure.
+If the wide character can be represented as a single-byte character,
+convert it with
+.Xr wctob 3 ,
+store the result in
+.Fa ch ,
+and return 1; otherwise, set
+.Va errno
+to
+.Er ERANGE
+and return \-1.
+In the C or POSIX locale, this simply reads a byte, but for any other
+locale, including UTF-8, this is rarely useful.
+.It Fn el_wpush
+Push the wide character string
+.Fa wcs
+back onto the input queue described in
+.Xr editline 7 .
+If the queue overflows, for example due to a recursive macro,
+or if an error occurs, for example because
+.Fa wcs
+is
+.Dv NULL
+or memory allocation fails, the function beeps at the user,
+but does not report the problem to the caller.
+.It Fn el_push
+Use the current locale to convert the multibyte string
+.Fa mbs
+to a wide character string, and pass the result to
+.Fn el_wpush .
+.It Fn el_parse
+Parses the
+.Fa argv
+array (which is
+.Fa argc
+elements in size)
+to execute builtin
+.Nm
+commands.
+If the command is prefixed with
+.Dq prog :
+then
+.Fn el_parse
+will only execute the command if
+.Dq prog
+matches the
+.Fa prog
+argument supplied to
+.Fn el_init .
+The return value is
+\-1 if the command is unknown,
+0 if there was no error or
+.Dq prog
+didn't match, or
+1 if the command returned an error.
+Refer to
+.Xr editrc 5
+for more information.
+.It Fn el_set
+Set
+.Nm
+parameters.
+.Fa op
+determines which parameter to set, and each operation has its
+own parameter list.
+Returns 0 on success, \-1 on failure.
+.Pp
+The following values for
+.Fa op
+are supported, along with the required argument list:
+.Bl -tag -width 4n
+.It Dv EL_PROMPT , Fa "char *(*f)(EditLine *)"
+Define prompt printing function as
+.Fa f ,
+which is to return a string that contains the prompt.
+.It Dv EL_PROMPT_ESC , Fa "char *(*f)(EditLine *)" , Fa "char c"
+Same as
+.Dv EL_PROMPT ,
+but the
+.Fa c
+argument indicates the start/stop literal prompt character.
+.Pp
+If a start/stop literal character is found in the prompt, the
+character itself
+is not printed, but characters after it are printed directly to the
+terminal without affecting the state of the current line.
+A subsequent second start/stop literal character ends this behavior.
+This is typically used to embed literal escape sequences that change the
+color/style of the terminal in the prompt.
+Note that the literal escape character cannot be the last character in the
+prompt, as the escape sequence is attached to the next character in the prompt.
+.Dv 0
+unsets it.
+.It Dv EL_REFRESH
+Re-display the current line on the next terminal line.
+.It Dv EL_RPROMPT , Fa "char *(*f)(EditLine *)"
+Define right side prompt printing function as
+.Fa f ,
+which is to return a string that contains the prompt.
+.It Dv EL_RPROMPT_ESC , Fa "char *(*f)(EditLine *)" , Fa "char c"
+Define the right prompt printing function but with a literal escape character.
+.It Dv EL_TERMINAL , Fa "const char *type"
+Define terminal type of the tty to be
+.Fa type ,
+or to
+.Ev TERM
+if
+.Fa type
+is
+.Dv NULL .
+.It Dv EL_EDITOR , Fa "const char *mode"
+Set editing mode to
+.Fa mode ,
+which must be one of
+.Dq emacs
+or
+.Dq vi .
+.It Dv EL_SIGNAL , Fa "int flag"
+If
+.Fa flag
+is non-zero,
+.Nm
+will install its own signal handler for the following signals when
+reading command input:
+.Dv SIGCONT ,
+.Dv SIGHUP ,
+.Dv SIGINT ,
+.Dv SIGQUIT ,
+.Dv SIGSTOP ,
+.Dv SIGTERM ,
+.Dv SIGTSTP ,
+and
+.Dv SIGWINCH .
+Otherwise, the current signal handlers will be used.
+.It Dv EL_BIND , Fa "const char *" , Fa "..." , Dv NULL
+Perform the
+.Ic bind
+builtin command.
+Refer to
+.Xr editrc 5
+for more information.
+.It Dv EL_ECHOTC , Fa "const char *" , Fa "..." , Dv NULL
+Perform the
+.Ic echotc
+builtin command.
+Refer to
+.Xr editrc 5
+for more information.
+.It Dv EL_SETTC , Fa "const char *" , Fa "..." , Dv NULL
+Perform the
+.Ic settc
+builtin command.
+Refer to
+.Xr editrc 5
+for more information.
+.It Dv EL_SETTY , Fa "const char *" , Fa "..." , Dv NULL
+Perform the
+.Ic setty
+builtin command.
+Refer to
+.Xr editrc 5
+for more information.
+.It Dv EL_TELLTC , Fa "const char *" , Fa "..." , Dv NULL
+Perform the
+.Ic telltc
+builtin command.
+Refer to
+.Xr editrc 5
+for more information.
+.It Dv EL_ADDFN , Fa "const char *name" , Fa "const char *help" , \
+Fa "unsigned char (*func)(EditLine *e, int ch)"
+Add a user defined function,
+.Fn func ,
+referred to as
+.Fa name
+which is invoked when a key which is bound to
+.Fa name
+is entered.
+.Fa help
+is a description of
+.Fa name .
+At invocation time,
+.Fa ch
+is the key which caused the invocation.
+The return value of
+.Fn func
+should be one of:
+.Bl -tag -width "CC_REDISPLAY"
+.It Dv CC_NORM
+Add a normal character.
+.It Dv CC_NEWLINE
+End of line was entered.
+.It Dv CC_EOF
+EOF was entered.
+.It Dv CC_ARGHACK
+Expecting further command input as arguments, do nothing visually.
+.It Dv CC_REFRESH
+Refresh display.
+.It Dv CC_REFRESH_BEEP
+Refresh display, and beep.
+.It Dv CC_CURSOR
+Cursor moved, so update and perform
+.Dv CC_REFRESH .
+.It Dv CC_REDISPLAY
+Redisplay entire input line.
+This is useful if a key binding outputs extra information.
+.It Dv CC_ERROR
+An error occurred.
+Beep, and flush tty.
+.It Dv CC_FATAL
+Fatal error, reset tty to known state.
+.El
+.It Dv EL_HIST , Fa "History *(*func)(History *, int op, ...)" , \
+Fa "const char *ptr"
+Defines which history function to use, which is usually
+.Fn history .
+.Fa ptr
+should be the value returned by
+.Fn history_init .
+.It Dv EL_EDITMODE , Fa "int flag"
+If
+.Fa flag
+is non-zero,
+editing is enabled (the default).
+Note that this is only an indication, and does not
+affect the operation of
+.Nm .
+At this time, it is the caller's responsibility to
+check this
+(using
+.Fn el_get )
+to determine if editing should be enabled or not.
+.It Dv EL_UNBUFFERED , Fa "int flag"
+If
+.Fa flag
+is zero,
+unbuffered mode is disabled (the default).
+In unbuffered mode,
+.Fn el_gets
+will return immediately after processing a single character.
+.It Dv EL_SAFEREAD , Fa "int flag"
+If the
+.Fa flag
+argument is non-zero, then
+.Nm editline
+attempts to recover from read errors, ignoring the first interrrupted
+error, and trying to reset the input file descriptor to reset non-blocking I/O.
+This is disabled by default, and desirable only when
+.Nm editline
+is used in shell-like applications.
+.It Dv EL_GETCFN , Fa "el_rfunc_t f"
+Whenever reading a character, use the function
+.Bd -ragged -offset indent -compact
+.Ft int
+.Fo f
+.Fa "EditLine *e"
+.Fa "wchar_t *wc"
+.Fc
+.Ed
+which stores the character in
+.Fa wc
+and returns 1 on success, 0 on end of file, or \-1 on I/O or encoding
+errors.
+Functions internally using it include
+.Fn el_wgets ,
+.Fn el_wgetc ,
+.Fn el_gets ,
+and
+.Fn el_getc .
+Initially, a builtin function is installed, and replacing it
+is discouraged because writing such a function is very error prone.
+The builtin function can be restored at any time by passing the
+special value
+.Dv EL_BUILTIN_GETCFN
+instead of a function pointer.
+.It Dv EL_CLIENTDATA , Fa "void *data"
+Register
+.Fa data
+to be associated with this EditLine structure.
+It can be retrieved with the corresponding
+.Fn el_get
+call.
+.It Dv EL_SETFP , Fa "int fd" , Fa "FILE *fp"
+Set the current
+.Nm editline
+file pointer for
+.Dq input
+.Fa fd
+=
+.Dv 0 ,
+.Dq output
+.Fa fd
+=
+.Dv 1 ,
+or
+.Dq error
+.Fa fd
+=
+.Dv 2
+from
+.Fa fp .
+.El
+.It Fn el_get
+Get
+.Nm
+parameters.
+.Fa op
+determines which parameter to retrieve into
+.Fa result .
+Returns 0 if successful, \-1 otherwise.
+.Pp
+The following values for
+.Fa op
+are supported, along with actual type of
+.Fa result :
+.Bl -tag -width 4n
+.It Dv EL_PROMPT , Fa "char *(*f)(EditLine *)" , Fa "char *c"
+Set
+.Fa f
+to a pointer to the function that displays the prompt.
+If
+.Fa c
+is not
+.Dv NULL ,
+set it to the start/stop literal prompt character.
+.It Dv EL_RPROMPT , Fa "char *(*f)(EditLine *)" , Fa "char *c"
+Set
+.Fa f
+to a pointer to the function that displays the prompt.
+If
+.Fa c
+is not
+.Dv NULL ,
+set it to the start/stop literal prompt character.
+.It Dv EL_EDITOR , Fa "const char **n"
+Set the name of the editor in
+.Fa n ,
+which will be one of
+.Dq emacs
+or
+.Dq vi .
+.It Dv EL_GETTC , Fa "const char *name" , Fa "void *value"
+If
+.Fa name
+is a valid
+.Xr termcap 5
+capability set
+.Fa value
+to the current value of that capability.
+.It Dv EL_SIGNAL , Fa "int *s"
+Set
+.Fa s
+to non-zero if
+.Nm
+has installed private signal handlers (see
+.Fn el_get
+above).
+.It Dv EL_EDITMODE , Fa "int *c"
+Set
+.Fa c
+to non-zero if editing is enabled.
+.It Dv EL_GETCFN , Fa "el_rfunc_t *f"
+Set
+.Fa f
+to a pointer to the function that reads characters, or to
+.Dv EL_BUILTIN_GETCFN
+if the builtin function is in use.
+.It Dv EL_CLIENTDATA , Fa "void **data"
+Set
+.Fa data
+to the previously registered client data set by an
+.Fn el_set
+call.
+.It Dv EL_UNBUFFERED , Fa "int *c"
+Set
+.Fa c
+to non-zero if unbuffered mode is enabled.
+.It Dv EL_SAFEREAD , Fa "int *c"
+Set
+.Fa c
+to non-zero if safe read is set.
+.It Dv EL_GETFP , Fa "int fd", Fa "FILE **fp"
+Set
+.Fa fp

+.Os
+.Sh NAME
+.Nm editline
+.Nd line editing user interface
+.Sh DESCRIPTION
+When a program using the
+.Xr editline 3
+library prompts for an input string using the function
+.Xr el_wgets 3 ,
+it reads characters from the terminal.
+Invalid input bytes that do not form characters are silently
+discarded.
+For each character read, one editor command is executed.
+The mapping of input characters to editor commands depends on the
+editing mode.
+There are three editing modes: vi insert mode, vi command mode,
+and emacs mode.
+The default is vi insert mode.
+The program can switch the default to emacs mode by using the
+.Xr el_set 3
+or
+.Xr el_parse 3
+functions, and the user can switch to emacs mode either in the
+.Xr editrc 5
+configuration file or interactively with the
+.Ic ed-command
+editor command, in all three cases executing the
+.Ic bind Fl e
+builtin command.
+.Pp
+If trying to read from the terminal results in end of file or an
+error, the library signals end of file to the program and does not
+return a string.
+.Ss Input character bindings
+All default bindings described below can be overridden by individual
+programs and can be changed with the
+.Xr editrc 5
+.Ic bind
+builtin command.
+.Pp
+In the following tables,
+.Sq Ctrl-
+indicates a character with the bit 0x40 flipped, and
+.Sq Meta-
+indicates a character with the bit 0x80 set.
+In vi insert mode and in emacs mode, all Meta-characters considered
+printable by the current
+.Xr locale 1
+are bound to
+.Ic ed-insert
+instead of to the editor command listed below.
+Consequently, in UTF-8 mode, most of the Meta-characters are not
+directly accessible because their code points are occupied by
+printable Unicode characters, and Meta-characters are usually input
+using the
+.Ic em-meta-next
+editor command.
+For example, to enter
+.Sq Meta-B
+in order to call the
+.Ic ed-prev-word
+editor command in emacs mode, call
+.Ic em-meta-next
+by pressing and releasing the escape key (or equivalently, Ctrl-[),
+then press and release the
+.Sq B
+key.
+If you have configured a Meta-key on your keyboard, for example
+with
+.Ql setxkbmap -option altwin:left_meta_win ,
+the Ctrl-Meta-characters are directly accessible.
+For example, to enter
+.Sq Ctrl-Meta-H
+in order to call the
+.Ic ed-delete-prev-word
+editor command in emacs mode, hold down the keys
+.Sq Ctrl ,
+.Sq Meta ,
+and
+.Sq H
+at the same time.
+Alternatively, press and release the escape key, then press and
+release
+.Sq Ctrl-H .
+.Pp
+In vi input mode, input characters are bound to the following editor
+commands by default:
+.Bl -column -offset indent "Ctrl-Z, TSTP" "ed-search-next-history"
+.It Ctrl-D, EOF Ta Ic vi-list-or-eof

+.Pp
+If standard output is not connected to a terminal device
+or
+.Xr el_set 3
+was used to set
+.Dv EL_EDITMODE
+to 0, all input character bindings are disabled and all characters
+typed are appended to the edit buffer.
+In that case, the edit buffer is returned to the program after a
+newline or carriage return character is typed, or after the first
+character typed if
+.Xr el_set 3
+was used to set
+.Dv EL_UNBUFFERED
+to non-zero.
+.Ss Editor commands
+Most editor commands accept an optional argument.
+The argument is entered by prefixing the editor command with one
+or more of the editor commands
+.Ic ed-argument-digit ,
+.Ic ed-digit ,
+.Ic em-universal-argument ,
+or
+.Ic vi-zero .
+When an argument is not provided, it defaults to 1.
+For most editor commands, the effect of an argument is to repeatedly
+execute the command that number of times.
+.Pp
+When talking about a character string from a left character to a
+right character, the left character is included in the string, while
+the right character is not included.
+.Pp
+If an editor command causes an error, the input character is discarded,
+no action occurs, and the terminal bell is rung.
+In case of a non-fatal error, the terminal bell is also rung,
+but the editor command takes effect anyway.
+.Pp
+In the following list, the default key bindings are listed after
+each editor command.
+.Bl -tag -width 4n
+.It Ic ed-argument-digit Pq vi command: 1 to 9; emacs: Meta-0 to Meta-9
+If in argument input mode, append the input digit to the argument
+being read.
+Otherwise, switch to argument input mode and use the input digit
+as the most significant digit of the argument.
+It is an error if the input character is not a digit or if the
+existing argument is already greater than a million.
+.It Ic ed-clear-screen Pq vi command: Ctrl-L; emacs: Ctrl-L, Ctrl-Meta-L
+Clear the screen and display the edit buffer at the top.
+Ignore any argument.
+.It Ic ed-command Pq vi command: So \&: Sc ; emacs: Meta-X, Meta-x
+Read a line from the terminal bypassing the normal line editing
+functionality and execute that line as an
+.Xr editrc 5
+builtin command.
+If in vi command mode, also switch back to vi insert mode.
+Ignore any argument.
+.It Ic ed-delete-next-char Pq vi command: x
+Delete the character at the cursor position.
+With an argument, delete that number of characters.
+In emacs mode, it is an error if the cursor is at the end of the
+edit buffer.
+In vi mode, the last character in the edit buffer is deleted in
+that case, and it is an error if the buffer is empty.
+.It Ic ed-delete-prev-char Pq vi command: X, Ctrl-H, BS, Ctrl-?, DEL
+Delete the character to the left of the cursor position.
+With an argument, delete that number of characters.
+It is an error if the cursor is at the beginning of the edit buffer.
+.It Ic ed-delete-prev-word Pq vi: Ctrl-W; emacs: Ctrl-Meta-H, Ctrl-Meta-?
+Move to the left to the closest beginning of a word, delete the
+string from that position to the cursor, and save it to the cut
+buffer.
+With an argument, delete that number of words.
+It is an error if the cursor is at the beginning of the edit buffer.
+.It Ic ed-digit Pq emacs: 0 to 9
+If in argument input mode, append the input digit to the argument
+being read.
+Otherwise, call
+.Ic ed-insert .
+It is an error if the input character is not a digit or if the
+existing argument is already greater than a million.
+.It Ic ed-end-of-file Pq not bound by default
+Discard the edit buffer and indicate end of file to the program.
+Ignore any argument.
+.It Ic ed-ignore Pq various
+Discard the input character and do nothing.
+.It Ic ed-insert Pq vi input: almost all; emacs: printable characters
+In insert mode, insert the input character left of the cursor
+position.
+In replace mode, overwrite the character at the cursor and move the
+cursor to the right by one character position.
+Accept an argument to do this repeatedly.
+It is an error if the input character is the NUL character (Ctrl-@).
+Failure to enlarge the edit buffer also results in an error.
+.It Ic ed-kill-line Pq vi command: D, Ctrl-K; emacs: Ctrl-K, Ctrl-U
+Delete the string from the cursor position to the end of the line
+and save it to the cut buffer.
+Ignore any argument.
+.It Ic ed-move-to-beg Pq vi command: ^, Ctrl-A; emacs: Ctrl-A
+In vi mode, move the cursor to the first non-space character in the
+edit buffer.
+In emacs mode, move the cursor to the beginning of the edit buffer.
+Ignore any argument.
+Can be used as a movement command after
+.Ic vi_change_meta ,
+.Ic vi_delete_meta ,

+.El
+.Ss Macros
+If an input character is bound to the editor command
+.Ic ed-sequence-lead-in ,
+.Nm
+attempts to call a macro.
+If the input character by itself forms the name of a macro, that
+macro is executed.
+Otherwise, additional input characters are read until the string
+read forms the name of a macro, in which case that macro is executed,
+or until the string read matches the beginning of none of the existing
+macro names, in which case the string including the final, mismatching
+character is discarded and the terminal bell is rung.
+.Pp
+There are two kinds of macros.
+Command macros execute a single editor command.
+Keyboard macros return a string of characters that is appended
+as a new line to the
+.Sx Input Queue .
+.Pp
+The following command macros are defined by default in vi command
+mode and in emacs mode:
+.Bl -column -offset indent "Esc O A, Esc O A" "em-exchange-mark"
+.It Esc \&[ A, Esc O A Ta Ic ed-prev-history
+.It Esc \&[ B, Esc O B Ta Ic ed-next-history
+.It Esc \&[ C, Esc O C Ta Ic ed-next-char
+.It Esc \&[ D, Esc O D Ta Ic ed-prev-char
+.It Esc \&[ F, Esc O F Ta Ic ed-move-to-end
+.It Esc \&[ H, Esc O H Ta Ic ed-move-to-beg
+.El
+.Pp
+In vi command mode, they are also defined by default without the
+initial escape character.
+.Pp
+In addition, the
+.Nm
+library tries to bind the strings generated by the arrow keys
+as reported by the
+.Xr terminfo 5
+database to these editor commands, unless that would clobber
+user settings.
+.Pp
+In emacs mode, the two-character string
+.Dq Ctrl-X Ctrl-X
+is bound to the
+.Ic em-exchange-mark
+editor command.
+.Ss Input Queue
+The
+.Nm
+library maintains an input queue operated in FIFO mode.
+Whenever it needs an input character, it takes the first character
+from the first line of the input queue.
+When the queue is empty, it reads from the terminal.
+.Pp
+A line can be appended to the end of the input queue in several ways:
+.Bl -dash -offset indent
+.It
+By calling one of the keyboard
+.Sx Macros .
+.It
+By calling the editor command
+.Ic vi-redo .
+.It
+By calling the editor command
+.Ic vi-alias .
+.It
+By pressing a key in emacs incremental search mode that doesn't
+have a special meaning in that mode but returns to normal emacs
+mode.
+.It
+If an application program directly calls the functions
+.Xr el_push 3
+or
+.Xr el_wpush 3 ,
+it can provide additional, program-specific ways
+of appending to the input queue.

+.Sh NAME
+.Nm editrc
+.Nd configuration file for editline library
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+The
+.Nm
+file defines various settings to be used by the
+.Xr editline 3
+library.
+.Pp
+The format of each line is:
+.Pp
+.Dl [prog:]command [arg ...]
+.Pp
+.Ar command
+is one of the
+.Xr editline 3
+builtin commands.
+Refer to
+.Sx BUILTIN COMMANDS
+for more information.
+.Pp
+.Ar prog
+is the program name string that a program defines when it calls
+.Xr el_init 3
+to set up
+.Xr editline 3 ,
+which is usually
+.Va argv[0] .
+.Ar command
+will be executed for any program which matches
+.Ar prog .
+.Pp
+.Ar prog
+may also be a
+.Xr regex 3
+style
+regular expression, in which case
+.Ar command
+will be executed for any program that matches the regular expression.
+.Pp
+If
+.Ar prog
+is absent,
+.Ar command
+is executed for all programs.
+.Sh BUILTIN COMMANDS
+The
+.Nm editline
+library has some builtin commands, which affect the way
+that the line editing and history functions operate.
+These are based on similar named builtins present in the
+.Xr tcsh 1
+shell.
+.Pp
+The following builtin commands are available:
+.Bl -tag -width 4n
+.It Ic bind Oo Fl aeklrsv Oc Op Ar key Op Ar command
+Without options and arguments, list all bound keys and macros, and
+the editor command or input string to which each one is bound.
+If only
+.Ar key
+is supplied, show the binding for that key or macro.
+If
+.Ar key command
+is supplied, bind the editor
+.Ar command
+to that key or macro.
+.Pp
+The options are as follows:
+.Bl -tag -width 4n
+.It Fl a
+List or change key bindings in the
+.Xr vi 1
+mode alternate (command mode) key map.
+.It Fl e
+Bind all keys to the standard GNU Emacs-like bindings.
+.It Fl k
+.Ar key
+is interpreted as a symbolic arrow key name, which may be one of
+.Sq up ,
+.Sq down ,
+.Sq left
+or
+.Sq right .
+.It Fl l
+List all editor commands and a short description of each.
+.It Fl r
+Remove the binding of the key or macro
+.Ar key .
+.It Fl s
+Define a keyboard macro rather than a key binding or command macro:
+.Ar command
+is taken as a literal string and appended to the input queue whenever
+.Ar key
+is typed.
+Bound keys and macros in
+.Ar command

+   or: $0 [OPTION]... -t DIRECTORY SRCFILES...
+   or: $0 [OPTION]... -d DIRECTORIES...
+
+In the 1st form, copy SRCFILE to DSTFILE.
+In the 2nd and 3rd, copy all SRCFILES to DIRECTORY.
+In the 4th, create DIRECTORIES.

+
+  -c            (ignored)
+  -C            install only if different (preserve data modification time)
+  -d            create directories instead of installing files.
+  -g GROUP      $chgrpprog installed files to GROUP.
+  -m MODE       $chmodprog installed files to MODE.
+  -o USER       $chownprog installed files to USER.
+  -p            pass -p to $cpprog.
+  -s            $stripprog installed files.
+  -S SUFFIX     attempt to back up existing files, with suffix SUFFIX.
+  -t DIRECTORY  install into DIRECTORY.
+  -T            report an error if DSTFILE is a directory.
+
+Environment variables override the default commands:
+  CHGRPPROG CHMODPROG CHOWNPROG CMPPROG CPPROG MKDIRPROG MVPROG
+  RMPROG STRIPPROG
+
+By default, rm is invoked with -f; when overridden with RMPROG,
+it's up to you to specify -f if you want it.
+
+If -S is not specified, no backups are attempted.

+#         of 'echo a\ b'.  This is slower than default on some shells.

+#         wrapping double-quotes.

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# Copyright'.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug in processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.

+# override it after sourcing this library to reflect the full set of

Subject: [PATCH 24/32] Bug#35489173 Upgrade the libedit library to the latest
 [patch 2]

Patch 2: Add cmake code based on the .ac and .am autotools files.

Only one relevant change to .ac and .am files, new source file reallocarr.c
Copy from old libedit directory:
  src/CMakeLists.txt
  src/config.h
and add the new file.

Rename src/makelist to src/makelist.in so we can subst @AWK@ in it.
Change path to current libedit in cmake/readline.cmake.

Change-Id: Ia7911132479ca0d0bd4aab6463144f2f446dee7e
(cherry picked from commit 1204c1c04c6b5cf9b9527c0a5f666456ce2610ce)

-Foundation, Inc.
-
-   This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  (Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.)
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You only need
-`configure.ac' if you want to change it or regenerate `configure' using
-a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not support the `VPATH'
-variable, you have to compile the package for one architecture at a
-time in the source code directory.  After you have installed the
-package for one architecture, use `make distclean' before reconfiguring
-for another architecture.
-
-Installation Names
-==================
-
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the `--target=TYPE' option to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-will cause the specified gcc to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX

-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.

-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  LT_SYS_LIBRARY_PATH
-              User-defined run-time library search path.
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

-*** is disabling shared libraries support.  We urge you to upgrade GNU
-*** binutils to release 2.16.91.0.3 or newer.  Another option is to modify
-*** your PATH or compiler configuration so that the native linker is

-## The problem is that when a header file which appears in a .P file
-## is deleted, the dependency causes make to die (because there is
-## typically no way to rebuild the header).  We avoid this by adding
-## dummy dependencies for each header file.  Too bad gcc doesn't do
-## this for us directly.
-## Some versions of gcc put a space before the ':'.  On the theory
-## that the space means something, we add a space to the output as
-## well.  hp depmode also adds that space, but also prefixes the VPATH

-.Sh DESCRIPTION
-The
-.Nm
-library provides generic line editing, history and tokenization functions,
-similar to those found in
-.Xr sh 1 .
-.Pp
-These functions are available in the
-.Nm libedit
-library (which needs the
-.Nm libtermcap
-library).
-Programs should be linked with
-.Fl ledit ltermcap .
-.Pp
-The
-.Nm
-library respects the
-.Ev LC_CTYPE
-locale set by the application program and never uses
-.Xr setlocale 3
-to change the locale.
-.Sh LINE EDITING FUNCTIONS
-The line editing functions use a common data structure,
-.Fa EditLine ,
-which is created by
-.Fn el_init
-or
-.Fn el_init_fd
-and freed by
-.Fn el_end .
-.Pp
-The wide-character functions behave the same way as their narrow
-counterparts.
-.Pp
-The following functions are available:
-.Bl -tag -width 4n
-.It Fn el_init
-Initialize the line editor, and return a data structure
-to be used by all other line editing functions, or
-.Dv NULL
-on failure.
-.Fa prog
-is the name of the invoking program, used when reading the
-.Xr editrc 5
-file to determine which settings to use.
-.Fa fin ,
-.Fa fout
-and
-.Fa ferr
-are the input, output, and error streams (respectively) to use.
-In this documentation, references to
-.Dq the tty
-are actually to this input/output stream combination.
-.It Fn el_init_fd
-Like
-.Fn el_init
-but allows specifying file descriptors for the
-.Xr stdio 3
-corresponding streams, in case those were created with
-.Xr funopen 3 .
-.It Fn el_end
-Clean up and finish with
-.Fa e ,
-assumed to have been created with
-.Fn el_init
-or
-.Fn el_init_fd .
-.It Fn el_reset
-Reset the tty and the parser.
-This should be called after an error which may have upset the tty's
-state.
-.It Fn el_gets
-Read a line from the tty.
-.Fa count
-is modified to contain the number of characters read.
-Returns the line read if successful, or
-.Dv NULL
-if no characters were read or if an error occurred.
-If an error occurred,
-.Fa count
-is set to \-1 and
-.Dv errno
-contains the error code that caused it.
-The return value may not remain valid across calls to
-.Fn el_gets
-and must be copied if the data is to be retained.
-.It Fn el_wgetc
-Read a wide character from the tty, respecting the current locale,
-or from the input queue described in
-.Xr editline 7
-if that is not empty, and store it in
-.Fa wc .
-If an invalid or incomplete character is found, it is discarded,
-.Va errno
-is set to
-.Er EILSEQ ,
-and the next character is read and stored in
-.Fa wc .
-Returns 1 if a valid character was read, 0 on end of file, or \-1 on
-.Xr read 2
-failure.
-In the latter case,
-.Va errno
-is set to indicate the error.
-.It Fn el_getc
-Read a wide character as described for
-.Fn el_wgetc
-and return 0 on end of file or \-1 on failure.
-If the wide character can be represented as a single-byte character,
-convert it with
-.Xr wctob 3 ,
-store the result in
-.Fa ch ,
-and return 1; otherwise, set
-.Va errno
-to
-.Er ERANGE
-and return \-1.
-In the C or POSIX locale, this simply reads a byte, but for any other
-locale, including UTF-8, this is rarely useful.
-.It Fn el_wpush
-Push the wide character string
-.Fa wcs
-back onto the input queue described in
-.Xr editline 7 .
-If the queue overflows, for example due to a recursive macro,
-or if an error occurs, for example because
-.Fa wcs
-is
-.Dv NULL
-or memory allocation fails, the function beeps at the user,
-but does not report the problem to the caller.
-.It Fn el_push
-Use the current locale to convert the multibyte string
-.Fa mbs
-to a wide character string, and pass the result to
-.Fn el_wpush .
-.It Fn el_parse
-Parses the
-.Fa argv
-array (which is
-.Fa argc
-elements in size)
-to execute builtin
-.Nm
-commands.
-If the command is prefixed with
-.Dq prog :
-then
-.Fn el_parse
-will only execute the command if
-.Dq prog
-matches the
-.Fa prog
-argument supplied to
-.Fn el_init .
-The return value is
-\-1 if the command is unknown,
-0 if there was no error or
-.Dq prog
-didn't match, or
-1 if the command returned an error.
-Refer to
-.Xr editrc 5
-for more information.
-.It Fn el_set
-Set
-.Nm
-parameters.
-.Fa op
-determines which parameter to set, and each operation has its
-own parameter list.
-Returns 0 on success, \-1 on failure.
-.Pp
-The following values for
-.Fa op
-are supported, along with the required argument list:
-.Bl -tag -width 4n
-.It Dv EL_PROMPT , Fa "char *(*f)(EditLine *)"
-Define prompt printing function as
-.Fa f ,
-which is to return a string that contains the prompt.
-.It Dv EL_PROMPT_ESC , Fa "char *(*f)(EditLine *)" , Fa "char c"
-Same as
-.Dv EL_PROMPT ,
-but the
-.Fa c
-argument indicates the start/stop literal prompt character.
-.Pp
-If a start/stop literal character is found in the prompt, the
-character itself
-is not printed, but characters after it are printed directly to the
-terminal without affecting the state of the current line.
-A subsequent second start/stop literal character ends this behavior.
-This is typically used to embed literal escape sequences that change the
-color/style of the terminal in the prompt.
-Note that the literal escape character cannot be the last character in the
-prompt, as the escape sequence is attached to the next character in the prompt.
-.Dv 0
-unsets it.
-.It Dv EL_REFRESH
-Re-display the current line on the next terminal line.
-.It Dv EL_RPROMPT , Fa "char *(*f)(EditLine *)"
-Define right side prompt printing function as
-.Fa f ,
-which is to return a string that contains the prompt.
-.It Dv EL_RPROMPT_ESC , Fa "char *(*f)(EditLine *)" , Fa "char c"
-Define the right prompt printing function but with a literal escape character.
-.It Dv EL_TERMINAL , Fa "const char *type"

-Set editing mode to
-.Fa mode ,
-which must be one of
-.Dq emacs
-or
-.Dq vi .
-.It Dv EL_SIGNAL , Fa "int flag"
-If
-.Fa flag
-is non-zero,
-.Nm
-will install its own signal handler for the following signals when
-reading command input:
-.Dv SIGCONT ,
-.Dv SIGHUP ,
-.Dv SIGINT ,
-.Dv SIGQUIT ,
-.Dv SIGSTOP ,
-.Dv SIGTERM ,
-.Dv SIGTSTP ,
-and
-.Dv SIGWINCH .
-Otherwise, the current signal handlers will be used.
-.It Dv EL_BIND , Fa "const char *" , Fa "..." , Dv NULL
-Perform the
-.Ic bind
-builtin command.
-Refer to
-.Xr editrc 5
-for more information.
-.It Dv EL_ECHOTC , Fa "const char *" , Fa "..." , Dv NULL
-Perform the
-.Ic echotc
-builtin command.
-Refer to
-.Xr editrc 5
-for more information.
-.It Dv EL_SETTC , Fa "const char *" , Fa "..." , Dv NULL
-Perform the
-.Ic settc
-builtin command.
-Refer to
-.Xr editrc 5
-for more information.
-.It Dv EL_SETTY , Fa "const char *" , Fa "..." , Dv NULL
-Perform the
-.Ic setty
-builtin command.
-Refer to
-.Xr editrc 5
-for more information.
-.It Dv EL_TELLTC , Fa "const char *" , Fa "..." , Dv NULL

-.Ic telltc
-builtin command.
-Refer to
-.Xr editrc 5
-for more information.
-.It Dv EL_ADDFN , Fa "const char *name" , Fa "const char *help" , \
-Fa "unsigned char (*func)(EditLine *e, int ch)"
-Add a user defined function,
-.Fn func ,
-referred to as
-.Fa name
-which is invoked when a key which is bound to
-.Fa name
-is entered.
-.Fa help
-is a description of
-.Fa name .
-At invocation time,
-.Fa ch
-is the key which caused the invocation.
-The return value of
-.Fn func
-should be one of:
-.Bl -tag -width "CC_REDISPLAY"
-.It Dv CC_NORM
-Add a normal character.
-.It Dv CC_NEWLINE
-End of line was entered.
-.It Dv CC_EOF
-EOF was entered.

-.El
-.It Dv EL_HIST , Fa "History *(*func)(History *, int op, ...)" , \
-Fa "const char *ptr"
-Defines which history function to use, which is usually
-.Fn history .
-.Fa ptr
-should be the value returned by
-.Fn history_init .
-.It Dv EL_EDITMODE , Fa "int flag"
-If
-.Fa flag
-is non-zero,
-editing is enabled (the default).
-Note that this is only an indication, and does not
-affect the operation of
-.Nm .
-At this time, it is the caller's responsibility to
-check this
-(using
-.Fn el_get )
-to determine if editing should be enabled or not.
-.It Dv EL_UNBUFFERED , Fa "int flag"
-If
-.Fa flag
-is zero,
-unbuffered mode is disabled (the default).
-In unbuffered mode,
-.Fn el_gets
-will return immediately after processing a single character.
-.It Dv EL_SAFEREAD , Fa "int flag"
-If the
-.Fa flag
-argument is non-zero, then
-.Nm editline
-attempts to recover from read errors, ignoring the first interrrupted
-error, and trying to reset the input file descriptor to reset non-blocking I/O.
-This is disabled by default, and desirable only when
-.Nm editline
-is used in shell-like applications.
-.It Dv EL_GETCFN , Fa "el_rfunc_t f"
-Whenever reading a character, use the function
-.Bd -ragged -offset indent -compact
-.Ft int

-.Fa "wchar_t *wc"
-.Fc
-.Ed
-which stores the character in
-.Fa wc
-and returns 1 on success, 0 on end of file, or \-1 on I/O or encoding
-errors.
-Functions internally using it include
-.Fn el_wgets ,
-.Fn el_wgetc ,
-.Fn el_gets ,
-and
-.Fn el_getc .
-Initially, a builtin function is installed, and replacing it
-is discouraged because writing such a function is very error prone.
-The builtin function can be restored at any time by passing the
-special value
-.Dv EL_BUILTIN_GETCFN
-instead of a function pointer.
-.It Dv EL_CLIENTDATA , Fa "void *data"
-Register
-.Fa data
-to be associated with this EditLine structure.
-It can be retrieved with the corresponding
-.Fn el_get
-call.

-.Fa fd
-=
-.Dv 2
-from
-.Fa fp .
-.El
-.It Fn el_get
-Get
-.Nm
-parameters.
-.Fa op
-determines which parameter to retrieve into

-.Dt EDITLINE 7
-.Os
-.Sh NAME
-.Nm editline
-.Nd line editing user interface
-.Sh DESCRIPTION
-When a program using the
-.Xr editline 3
-library prompts for an input string using the function
-.Xr el_wgets 3 ,
-it reads characters from the terminal.
-Invalid input bytes that do not form characters are silently
-discarded.
-For each character read, one editor command is executed.
-The mapping of input characters to editor commands depends on the
-editing mode.
-There are three editing modes: vi insert mode, vi command mode,
-and emacs mode.
-The default is vi insert mode.
-The program can switch the default to emacs mode by using the
-.Xr el_set 3
-or
-.Xr el_parse 3
-functions, and the user can switch to emacs mode either in the
-.Xr editrc 5
-configuration file or interactively with the
-.Ic ed-command
-editor command, in all three cases executing the
-.Ic bind Fl e
-builtin command.
-.Pp
-If trying to read from the terminal results in end of file or an
-error, the library signals end of file to the program and does not
-return a string.
-.Ss Input character bindings
-All default bindings described below can be overridden by individual
-programs and can be changed with the
-.Xr editrc 5
-.Ic bind
-builtin command.
-.Pp
-In the following tables,
-.Sq Ctrl-
-indicates a character with the bit 0x40 flipped, and
-.Sq Meta-
-indicates a character with the bit 0x80 set.
-In vi insert mode and in emacs mode, all Meta-characters considered
-printable by the current
-.Xr locale 1
-are bound to
-.Ic ed-insert
-instead of to the editor command listed below.
-Consequently, in UTF-8 mode, most of the Meta-characters are not
-directly accessible because their code points are occupied by
-printable Unicode characters, and Meta-characters are usually input
-using the
-.Ic em-meta-next
-editor command.
-For example, to enter
-.Sq Meta-B
-in order to call the
-.Ic ed-prev-word
-editor command in emacs mode, call
-.Ic em-meta-next
-by pressing and releasing the escape key (or equivalently, Ctrl-[),
-then press and release the
-.Sq B
-key.
-If you have configured a Meta-key on your keyboard, for example
-with
-.Ql setxkbmap -option altwin:left_meta_win ,
-the Ctrl-Meta-characters are directly accessible.
-For example, to enter
-.Sq Ctrl-Meta-H
-in order to call the
-.Ic ed-delete-prev-word
-editor command in emacs mode, hold down the keys
-.Sq Ctrl ,
-.Sq Meta ,
-and
-.Sq H
-at the same time.
-Alternatively, press and release the escape key, then press and
-release
-.Sq Ctrl-H .
-.Pp
-In vi input mode, input characters are bound to the following editor
-commands by default:
-.Bl -column -offset indent "Ctrl-Z, TSTP" "ed-search-next-history"
-.It Ctrl-D, EOF Ta Ic vi-list-or-eof

-If standard output is not connected to a terminal device
-or
-.Xr el_set 3
-was used to set
-.Dv EL_EDITMODE
-to 0, all input character bindings are disabled and all characters
-typed are appended to the edit buffer.
-In that case, the edit buffer is returned to the program after a
-newline or carriage return character is typed, or after the first
-character typed if
-.Xr el_set 3
-was used to set
-.Dv EL_UNBUFFERED
-to non-zero.
-.Ss Editor commands
-Most editor commands accept an optional argument.
-The argument is entered by prefixing the editor command with one
-or more of the editor commands
-.Ic ed-argument-digit ,
-.Ic ed-digit ,
-.Ic em-universal-argument ,
-or
-.Ic vi-zero .
-When an argument is not provided, it defaults to 1.
-For most editor commands, the effect of an argument is to repeatedly
-execute the command that number of times.
-.Pp
-When talking about a character string from a left character to a
-right character, the left character is included in the string, while
-the right character is not included.
-.Pp
-If an editor command causes an error, the input character is discarded,
-no action occurs, and the terminal bell is rung.
-In case of a non-fatal error, the terminal bell is also rung,
-but the editor command takes effect anyway.

-.El
-.Ss Macros
-If an input character is bound to the editor command
-.Ic ed-sequence-lead-in ,
-.Nm
-attempts to call a macro.
-If the input character by itself forms the name of a macro, that
-macro is executed.
-Otherwise, additional input characters are read until the string
-read forms the name of a macro, in which case that macro is executed,
-or until the string read matches the beginning of none of the existing
-macro names, in which case the string including the final, mismatching
-character is discarded and the terminal bell is rung.
-.Pp
-There are two kinds of macros.
-Command macros execute a single editor command.
-Keyboard macros return a string of characters that is appended
-as a new line to the
-.Sx Input Queue .
-.Pp
-The following command macros are defined by default in vi command
-mode and in emacs mode:
-.Bl -column -offset indent "Esc O A, Esc O A" "em-exchange-mark"
-.It Esc \&[ A, Esc O A Ta Ic ed-prev-history
-.It Esc \&[ B, Esc O B Ta Ic ed-next-history
-.It Esc \&[ C, Esc O C Ta Ic ed-next-char
-.It Esc \&[ D, Esc O D Ta Ic ed-prev-char
-.It Esc \&[ F, Esc O F Ta Ic ed-move-to-end
-.It Esc \&[ H, Esc O H Ta Ic ed-move-to-beg
-.El
-.Pp
-In vi command mode, they are also defined by default without the
-initial escape character.
-.Pp
-In addition, the
-.Nm
-library tries to bind the strings generated by the arrow keys
-as reported by the
-.Xr terminfo 5
-database to these editor commands, unless that would clobber
-user settings.
-.Pp
-In emacs mode, the two-character string
-.Dq Ctrl-X Ctrl-X
-is bound to the
-.Ic em-exchange-mark
-editor command.
-.Ss Input Queue
-The
-.Nm
-library maintains an input queue operated in FIFO mode.
-Whenever it needs an input character, it takes the first character
-from the first line of the input queue.
-When the queue is empty, it reads from the terminal.
-.Pp
-A line can be appended to the end of the input queue in several ways:
-.Bl -dash -offset indent
-.It
-By calling one of the keyboard
-.Sx Macros .
-.It
-By calling the editor command
-.Ic vi-redo .
-.It
-By calling the editor command
-.Ic vi-alias .
-.It
-By pressing a key in emacs incremental search mode that doesn't
-have a special meaning in that mode but returns to normal emacs
-mode.
-.It
-If an application program directly calls the functions
-.Xr el_push 3
-or
-.Xr el_wpush 3 ,
-it can provide additional, program-specific ways
-of appending to the input queue.

-.Sh NAME
-.Nm editrc
-.Nd configuration file for editline library
-.Sh SYNOPSIS
-.Nm
-.Sh DESCRIPTION
-The
-.Nm
-file defines various settings to be used by the
-.Xr editline 3
-library.
-.Pp
-The format of each line is:
-.Pp
-.Dl [prog:]command [arg ...]
-.Pp
-.Ar command
-is one of the
-.Xr editline 3
-builtin commands.
-Refer to
-.Sx BUILTIN COMMANDS
-for more information.
-.Pp
-.Ar prog
-is the program name string that a program defines when it calls
-.Xr el_init 3
-to set up
-.Xr editline 3 ,
-which is usually
-.Va argv[0] .
-.Ar command
-will be executed for any program which matches
-.Ar prog .
-.Pp
-.Ar prog
-may also be a
-.Xr regex 3
-style
-regular expression, in which case
-.Ar command
-will be executed for any program that matches the regular expression.
-.Pp
-If
-.Ar prog
-is absent,
-.Ar command
-is executed for all programs.
-.Sh BUILTIN COMMANDS
-The
-.Nm editline
-library has some builtin commands, which affect the way
-that the line editing and history functions operate.
-These are based on similar named builtins present in the
-.Xr tcsh 1
-shell.
-.Pp
-The following builtin commands are available:
-.Bl -tag -width 4n
-.It Ic bind Oo Fl aeklrsv Oc Op Ar key Op Ar command
-Without options and arguments, list all bound keys and macros, and
-the editor command or input string to which each one is bound.
-If only
-.Ar key
-is supplied, show the binding for that key or macro.
-If
-.Ar key command
-is supplied, bind the editor
-.Ar command
-to that key or macro.
-.Pp
-The options are as follows:
-.Bl -tag -width 4n
-.It Fl a
-List or change key bindings in the
-.Xr vi 1
-mode alternate (command mode) key map.
-.It Fl e
-Bind all keys to the standard GNU Emacs-like bindings.
-.It Fl k
-.Ar key
-is interpreted as a symbolic arrow key name, which may be one of
-.Sq up ,
-.Sq down ,
-.Sq left
-or
-.Sq right .
-.It Fl l
-List all editor commands and a short description of each.
-.It Fl r
-Remove the binding of the key or macro
-.Ar key .
-.It Fl s
-Define a keyboard macro rather than a key binding or command macro:
-.Ar command
-is taken as a literal string and appended to the input queue whenever
-.Ar key
-is typed.
-Bound keys and macros in
-.Ar command
-are themselves reinterpreted, and this continues for ten levels of
-interpretation.
-.It Fl v
-Bind all keys to the standard
-.Xr vi 1 Ns -like
-bindings.
-.El
-.Pp
-The
-.Xr editline 7
-manual documents all editor commands and contains more information
-about macros and the input queue.
-.Pp
-.Ar key
-and
-.Ar command
-can contain control characters of the form
-.Sm off
-.Sq No ^ Ar character
-.Sm on
-.Po
-e.g.\&
-.Sq ^A
-.Pc ,
-and the following backslashed escape sequences:
-.Pp
-.Bl -tag -compact -offset indent -width 4n
-.It Ic \ea
-Bell
-.It Ic \eb
-Backspace
-.It Ic \ee
-Escape
-.It Ic \ef
-Formfeed
-.It Ic \en
-Newline
-.It Ic \er
-Carriage return
-.It Ic \et
-Horizontal tab
-.It Ic \ev
-Vertical tab
-.Sm off
-.It Sy \e Ar nnn
-.Sm on
-The ASCII character corresponding to the octal number
-.Ar nnn .
-.El
-.Pp
-.Sq \e
-nullifies the special meaning of the following character,
-if it has any, notably
-.Sq \e
-and
-.Sq ^ .
-.It Ic echotc Oo Fl sv Oc Ar arg Ar ...
-Exercise terminal capabilities given in
-.Ar arg ... .
-If
-.Ar arg
-is
-.Sq baud ,
-.Sq cols ,
-.Sq lines ,
-.Sq rows ,
-.Sq meta ,
-or
-.Sq tabs ,
-the value of that capability is printed, with
-.Dq yes
-or
-.Dq no
-indicating that the terminal does or does not have that capability.
-.Pp
-.Fl s
-returns an empty string for non-existent capabilities, rather than
-causing an error.
-.Fl v
-causes messages to be verbose.
-.It Ic edit Op Li on | Li off
-Enable or disable the
-.Nm editline
-functionality in a program.
-.It Ic history Ar list | Ar size Dv n | Ar unique Dv n
-The
-.Ar list
-command lists all entries in the history.
-The
-.Ar size
-command sets the history size to
-.Dv n
-entries.
-The
-.Ar unique
-command controls if history should keep duplicate entries.
-If
-.Dv n
-is non zero, only keep unique history entries.
-If
-.Dv n
-is zero, then keep all entries (the default).
-.It Ic settc Ar cap Ar val
-Set the terminal capability
-.Ar cap
-to
-.Ar val ,
-as defined in
-.Xr termcap 5 .
-No sanity checking is done.
-.It Ic setty Oo Fl a Oc Oo Fl d Oc Oo Fl q Oc Oo Fl x Oc Oo Ar +mode Oc \
-Oo Ar -mode Oc Oo Ar mode Oc Oo Ar char=c Oc
-Control which tty modes that
-.Nm
-won't allow the user to change.
-.Fl d ,
-.Fl q
-or
-.Fl x
-tells
-.Ic setty
-to act on the
-.Sq edit ,
-.Sq quote
-or
-.Sq execute
-set of tty modes respectively; defaulting to
-.Fl x .
-.Pp
-Without other arguments,
-.Ic setty
-lists the modes in the chosen set which are fixed on
-.Po
-.Sq +mode
-.Pc
-or off
-.Po
-.Sq -mode
-.Pc .
-.Fl a
-lists all tty modes in the chosen set regardless of the setting.
-With
-.Ar +mode ,
-.Ar -mode
-or
-.Ar mode ,
-fixes
-.Ar mode
-on or off or removes control of
-.Ar mode
-in the chosen set.
-.Pp
-.Ic Setty
-can also be used to set tty characters to particular values using
-.Ar char=value .
-If
-.Ar value
-is empty
-then the character is set to
-.Dv _POSIX_VDISABLE .
-.It Ic telltc
-List the values of all the terminal capabilities (see
-.Xr termcap 5 ) .

-## ------ ##
-## Usage. ##
-## ------ ##
-
-# This file is a library for parsing options in your shell scripts along
-# with assorted other useful supporting features that you can make use
-# of too.
-#
-# For the simplest scripts you might need only:
-#
-#   #!/bin/sh
-#   . relative/path/to/funclib.sh
-#   . relative/path/to/options-parser
-#   scriptversion=1.0
-#   func_options ${1+"$@"}
-#   eval set dummy "$func_options_result"; shift
-#   ...rest of your script...
-#
-# In order for the '--version' option to work, you will need to have a
-# suitably formatted comment like the one at the top of this file
-# starting with '# Written by ' and ending with '# warranty; '.
-#
-# For '-h' and '--help' to work, you will also need a one line
-# description of your script's purpose in a comment directly above the
-# '# Written by ' line, like the one at the top of this file.
-#
-# The default options also support '--debug', which will turn on shell
-# execution tracing (see the comment above debug_cmd below for another
-# use), and '--verbose' and the func_verbose function to allow your script
-# to display verbose messages only when your user has specified
-# '--verbose'.
-#
-# After sourcing this file, you can plug processing for additional
-# options by amending the variables from the 'Configuration' section
-# below, and following the instructions in the 'Option parsing'
-# section further down.
-
-## -------------- ##
-## Configuration. ##
-## -------------- ##
-
-# You should override these variables in your script after sourcing this
-# file so that they reflect the customisations you have added to the
-# option parser.
-
-# The usage line for option parsing errors and the start of '-h' and
-# '--help' output messages. You can embed shell variables for delayed
-# expansion at the time the message is displayed, but you will need to
-# quote other shell meta-characters carefully to prevent them being
-# expanded when the contents are evaled.
-usage='$progpath [OPTION]...'
-
-# Short help message in response to '-h' and '--help'.  Add to this or
-# override it after sourcing this library to reflect the full set of
-# options your script accepts.
-usage_message="\

-   -W, --warnings=CATEGORY

Subject: [PATCH 28/32] Bug #33568767 Upgrade to libedit 20210910-3.1

Additional patch for 5.7 only.
Add -std=c99 to C flags, since we build with older compilers where
this is not the default.
