This commit enables optional features that are enabled by default in the generated parser.
For now, only some of the helpers and filename are generated based on this new option, but this will change in the future most likely.
Resolves#421
* Add some useful debug information to some exceptions
* Add guard for visitor functions preventing from cryptic errors due to incomplete visitors
* Add guard for js generator for preventing from cryptic errors due to incarrect stack manipulations
* 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.
* 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 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).
* Do not indent backtick quoted strings in initializer or rule action code blocks
* Use const instead of var for ESLint happiness
* Fix ESLint issues for double quotes and indent6
Generating AMD/UMD dependencies lead to an error:
$ bin/pegjs --format amd --dependency $:jquery examples/arithmetics.pegjs
dependencyIds is not defined
$ bin/pegjs --format umd --dependency $:jquery examples/arithmetics.pegjs
dependencyIds is not defined
This commit fixes the problem, which was caused by a mistake done in
d2569b9bf3.
Running ESLint on generated code with the configuration used on PEG.js
itself produces a lot of errors. This commit fixes some unnecessary ones
caught by these rules:
- max-len
- new-cap
- newline-before-return
- no-unused-vars

Follow-up to #407.
Before this commit, continuation lines of multi-line values in variable
declaration initializers were aligned with the variable name:
let foo = {
a: 5,
b: 6
};
This was highly irregular, maintenance intensive, and made declarations
look different from assignments.
This commit changes the indentation to be more regular and similar to
assignments:
let foo = {
a: 5,
b: 6
};
