27 |
| -*** START TESTING *** |
| 25 | +// initialize the php parser factory class |
| 26 | +var engine = require('php-parser'); |
| 27 | +// initialize a new parser instance |
| 28 | +var parser = new engine({ |
| 29 | + // some options : |
| 30 | + parser: { |
| 31 | + extractDoc: true |
| 32 | + }, |
| 33 | + ast: { |
| 34 | + withPositions: true |
| 35 | + } |
| 36 | +}); |
| 37 | + |
| 38 | +// Retrieve the AST from the specified source |
| 39 | +var AST = parser.parseEval('echo "Hello World";'); |
| 40 | +// AST.kind === 'program'; |
| 41 | +// AST.children[0].kind === 'echo'; |

| -T_ECHO T_CONSTANT_ENCAPSED_STRING ; |
| 43 | +// Retrieve an array of tokens (same as php function token_get_all) |

| 71 | +API Overview |
| 72 | +------------ |
51 | 73 |
|
52 |
| -```js |
53 |
| -// initialize a new parser instance |
54 |
| -var parser = require('php-parser').create(); |
| 74 | +The main API exposes a class with the following methods : |
55 | 75 |
|
56 |
| -// how to retrieve the AST |
57 |
| -var AST = parser.parseEval('echo "Hello World";'); |
| 76 | +- **parseEval**(String buffer) : parse a PHP code in eval style mode (without php open tags) |
| 77 | +- **parseCode**(String buffer, String filename) : parse a PHP code by using php open tags. |
| 78 | +- **tokenGetAll**(String buffer) : retrieves a list of all tokens from the specified input. |
58 | 79 |
|
59 |
| -// how to list tokens |
60 |
| -var tokens = parser.tokenGetAll('<?php echo "Hello World";'); |
61 |
| -``` |
| 80 | +You can also [pass options](https://github.com/glayzzle/php-parser/wiki/Options) that change the behavior of the parser/lexer. |

| -If you want to change/fix the lexer you will find code to `./src/lexer/`. |
68 |
| -You can also implement the parser, the code is into `./src/parser/`. |
69 |
| -To check your changes add tests into `./test/parser/`, and run `npm run test`. |
70 |
| -Try to keep or improve the coverage levels. |
