- Added 'test/package.json' for dependencies used by spec tests
- Changed package names of local tools to reflect actual usage
- Removed bins for local tools (using files via 'node [file]' command)
- Updated help text for the CLIs of local tools to reflect changes
- Updated READMEs for tools
- Moved babel dependencies to 'tools/bundle/package.json'
- 'tools/bundle' now only logs created and watching
- Updated scripts in root package.json
- use value plucking
- remove helpers not needed now
- types in OPS_* are now returned by *Operator
- RESERVED_WORDS is now a `Object<Identifier,true>`
- use ES2015+ JavaScript
- cleanup source code
This test broke down aftert I intergrated the AST utils directly into the Grammar class, then I had problems importing the PEG.js parser to use the Grammar class, but found a workaround using 'process.cwd()'
All comments stored in the `comments` property of the `grammar` node.
Comments extracted only if the `extractComments` options set to `true` when you generate parser.
This property is object with mapping start offset of comment to comment object, that looks like:
```js
{
text: 'text in the comment, just after // or /* and before */',
multiline: true|false,// true for /**/ comments, false for // comments
location: location()
}
```
* Split 'consts' collection by content types into:
- literals: for literal expressions, like `"a"`
- classes: for character class expressions, like `[a]`
- expectations: for constants describing expected values when parse failed
- functions: for constants with function code
* Move any JavaScript code generation from 'generateBytecode' to 'generateJs'.
* Rename opcode 'MATCH_REGEXP' to 'MATCH_CLASS' (name reflects purpose, not implementation).
* Replace 'PUSH' opcode with 'PUSH_EMPTY_STRING' opcode because it is only used with empty strings
Before there used to be some internal utility methods for arrays and objects, but as the code base moved to ES5+ use case only, these were removed in favour of native alternatives, but most of these were only beneficial for arrays.
This commit add's common utility methods for objects, and also exposes these as they can be used by plugin developer's on the PEG.js AST.
Before this commit error looks like (for input `start = break:'a'`)
> Expected "!", "$", "&", "(", "*", "+", ".", "/", "/*", "//", ";", "?", character class, code block, comment, end of line, identifier, literal, or whitespace but ":" found.
After this error looks like
> Label can't be a reserved word "break".
* Optimization: do not generate unreachable calls |peg$fail| and constants for it (local to the rule).
* Optimization: do not generate unreachable calls |peg$fail| and constants for it (non-local to rule).
* Remove stack manipulations from FAIL opcode and rename FAIL to EXPECT
* Always save the expected values regardless of the match result of expression
* Remove unnecessary check for match result in the `named` node
* Collect and process expectations from predicates
This commit ensures that all modules outside 'lib' are importing 'lib/peg.js' so that VS Code automatically gets 'lib/peg.d.ts'.
An alias module for 'lib/peg.js' called 'pegjs-dev' was made for test files at 'test/node_modules/pegjs-dev.js'
The css files used in the benchmark contained 2 files for IE that contained syntax errors. These files weren't actually used by the benchmark, but were still in the repository.
