Among other things, it allows + optimizing generated parsers for parsing speed or code size using the + `optimize` option of the `PEG.buildParser` method or the `--optimize`/`-o` + option on the command-line. All internal identifiers in generated code now + also have a `peg$` prefix to discourage their use and avoid conflicts. + [[#35](https://github.com/dmajda/pegjs/issues/35), + [#92](https://github.com/dmajda/pegjs/issues/92)] + + * Completely redesigned error handling. Instead of returning `null` inside + actions to indicate match failure, new `expected` and `error` functions can + be called to trigger an error. Also, expectation inside the `SyntaxError` + exceptions are now structured to allow easier machine processing. + [[#198](https://github.com/dmajda/pegjs/issues/198)] + + * Implemented a plugin API. The list of plugins to use can be specified using + the `plugins` option of the `PEG.buildParser` method or the `--plugin` + option on the command-line. Also implemented the `--extra-options` and + `--extra-options-file` command-line options, which are mainly useful to pass + additional options to plugins. + [[#106](https://github.com/dmajda/pegjs/issues/106)] + + * Made `offset`, `line` and `column` functions, not variables. They are now + available in all parsers and return lazily-computed position data. Removed + now useless `trackLineAndColumn` option of the `PEG.buildParser` method and + the `--track-line-and-column` option on the command-line. + + * Added a new `text` function. When called inside an action, it returns the + text matched by action's expression. + [[#131](https://github.com/dmajda/pegjs/issues/131)] + + * Added a new `$` operator. It extracts matched strings from expressions. + + * The `?` operator now returns `null` on unsuccessful match. + + * Predicates now always return `undefined`. + + * Replaced the `startRule` parameter of the `parse` method in generated + parsers with more generic `options` parameter. The start rule can now be + specified as the `startRule` option. The `options` parameter can be also + used to pass custom options to the parser because it is visible as the + `options` variable inside parser code. + [[#37](https://github.com/dmajda/pegjs/issues/37)] + + * The list of allowed start rules of a generated parser now has to be + specified explicitly using the `allowedStartRules` option of the + `PEG.buildParser` method or the `--allowed-start-rule` option on the + command-line. This will make certain optimizations like rule inlining easier + in the future. + + * Removed the `toSource` method of generated parsers and introduced a new + `output` option of the `PEG.buildParser` method. It allows callers to + specify whether they want to get back the parser object or its source code. + + * The source code is now a valid npm package. This makes using development + versions easier. + [[#32](https://github.com/dmajda/pegjs/issues/32)] + + * Generated parsers are now ~25% faster and ~62%/~3% smaller (when optimized + for size/speed) than those generated by 0.7.0. + + * Requires Node.js 0.8.0+. + +### Small Changes + + * `bin/pegjs` now outputs just the parser source if the value of the + `--export-var` option is empty. This makes embedding generated parsers into + other files easier. + [[#143](https://github.com/dmajda/pegjs/issues/143)] + + * Changed the value of the `name` property of `PEG.GrammarError` instances + from “PEG.GrammarError” to just “GrammarError”. This better reflects the + fact that PEG.js can get required with different variable name than `PEG`. + + * Setup prototype chain for `PEG.GrammarError` correctly. + + * Setup prototype chain for `SyntaxError` in generated parsers correctly. + + * Fixed error messages in certain cases with trailing input + [[#119](https://github.com/dmajda/pegjs/issues/119)] + + * Fixed code generated for classes starting with `\^`. + [[#125](https://github.com/dmajda/pegjs/issues/125)] + + * Fixed too eager proxy rules removal. + [[#137](https://github.com/dmajda/pegjs/issues/137)] + + * Added a license to all vendored libraries. + [[#207](https://github.com/dmajda/pegjs/issues/207)] + + * Converted the test suite from QUnit to Jasmine, cleaning it up on the way. + + * Travis CI integration. + + * Various internal code improvements and fixes. + + * Various generated code improvements and fixes. + + * Various example grammar improvements and fixes. + + * Improved `README.md`. + + * Converted `CHANGELOG` to Markdown. + 0.7.0 -----
