* 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'
This is related to my last commit. I've updated all the JavaScript files to satisfy 'eslint-config-futagozaryuu', my eslint configuration.
I'm sure I've probally missed something, but I've run all NPM scripts and Gulp tasks, fixed any bugs that cropped up, and updated some stuff (mainly related to generated messages), so as far as I can, tell this conversion is over (I know I've probally jixed it just by saying this ;P).
Was using 'eslint-config-dmajda' by @dmajda, but since it's diffucult for me to use multiple styles across multiple projects, I'm switching to my own 'eslint-config-futagozaryuu'.
- Moved benchmark to test/benchmark
- Moved tests to test/spec
- Removed individual servers
- Implemented single test server
- Moved server assets to test/server
- Updated Gulpfile.js
- Moved tools/impact to test/impact
This commit move's nearly all code related to testing the PEG.js module into the test directory, and also ensures they run as they did before the move.
