This extension adds Progress 4GL/OpenABL language support to the Zed editor.

• Syntax highlighting for Progress 4GL/OpenABL files
• Support for common file extensions (.p, .i, .w, .cls)
• Recognition of:
  • Keywords and control structures
  • Data types
  • Functions and procedures
  • Classes and interfaces
  • Variables and field references
  • Comments (both line and block style)
  • String literals
  • Numbers and operators
  • Preprocessor directives

1. Clone this repository:

   git clone https://github.com/vasiv/zed-progress.git

2. Build the extension:

   cargo build --release

3. Install the extension in Zed:

   • Open Zed
   • Press Cmd+Shift+P to open the command palette
   • Select "Extensions: Install Extension"
   • Choose the built extension from the target/release directory

The extension automatically activates for files with the following extensions:

• .p (Progress source files)
• .i (Include files)
• .w (Window files)
• .cls (Class files)

This extension uses:

• tree-sitter-abl for parsing
• Zed's extension API for syntax highlighting and language support

1. Ensure you have Rust installed
2. Clone the repository
3. Run cargo build

Create a test file with the .p extension and open it in Zed to verify syntax highlighting.

Example:

/* Example Progress 4GL code */
DEFINE VARIABLE customer AS CHARACTER NO-UNDO.
DEFINE TEMP-TABLE tt_customer
    FIELD cust_num AS INTEGER
    FIELD name AS CHARACTER
    INDEX cust_num IS PRIMARY UNIQUE cust_num.

PROCEDURE getCustomer:
    DEFINE INPUT PARAMETER p_cust_num AS INTEGER.
    DEFINE OUTPUT PARAMETER p_name AS CHARACTER.
    
    FIND FIRST customer WHERE customer.cust_num = p_cust_num NO-LOCK.
    p_name = customer.name.
END PROCEDURE.
