be sorted out now.

External grammar libraries

4.0.0

Released: 2024-02-13

Major Changes

• #379 Fix infinite recursion
  issue by moving reportInfiniteRecursion to the new prepare pass, and having
  it fail after finding the first issue. This will require plugin authors
  to ensure that reportInfiniteRecursion is in the new pass correctly.
• #417 BREAKING: change to AST to
  allow topLevelInitializer and initializer to be arrays, in support of
  multi-file inputs. This will require plugin updates. The CLI and API now
  take multiple files as input, where the first file is your main library, and
  subsequent files consist of a library of other rules. The CLI can take file
  names of the form npm:<package-name>/<filename> to load library rules from
  an NPM package that is installed relative to the previous non-npm file name,
  or to the current working directory if this is the first file name.
• #420 BREAKING: Node v16+ is now
  required for running the CLI or using Peggy as a library. Generated code
  still targets older runtimes.
• #456 BREAKING: Allow imports
  from external compiled grammars inside a source grammar, using import {rule} from "external.js". Note that this syntax will generate either
  import or require in the JavaScript output, depending on the value of
  the format parameter. This will need explicit support from
  plugins, with a few new AST node types and a few visitor changes.
• #463 Drop support for
  Internet Explorer. Move to eslint flat configs in order to lint minimized
  browser code for compatibility with
  defaults, maintained node versions, not op_mini all.

Minor Changes

• #400 Use @generated in generated
  code
• #404 Add support for -w/--watch
  to the command line interface.
• #415 Added browser key to package.json, pointing to Webpack output.
• #420 Updated dependencies to
  avoid audit warnings.
• #425 Add a pass to simplify single-character choices
• #427 Avoid double extraction of
  substrings in various MATCH_ bytecodes
• #430 Make generate-js.js ts clean
• #432 Add peggy.code-workspace
• #435 Setup tsconfig to detect use of library functions from es6 or later
• #436 Get rid of tsd
• #437 Better type checking for visitor
• #438 Make test build deterministic
• #439 Make peg$computePosDetails a little faster
• #440 Create directories for
  output and source-map if they do not exist, rather than erroring.
• #446 Add a right-associative ExponentiationExpression rule (operator **) to javascript.pegjs example grammar.
• #451 Make stack.js ts clean
• #452 Fixes to prepare generate-bytecode.js for ts-check
• #453 Make generate-bytecode.js ts-clean
• #460 Allow -t and -T testing
  from the CLI with --format es.

Bug Fixes

More cleanups

3.0.2

Released: 2023-03-21

Minor Changes

• #392 Removed the --optimize command line argument, which has been invalid since v1.2. From @hildjj.

Bug Fixes

• #371 Error using online Peggy - "Can't find variable: util". From @hildjj.
• #374 CLI throws exception on grammar errors. From @hildjj
• #381 Repetitions with code blocks for min or max not handling non-integer returns correctly. From @hildjj.
• #382 Update grammarSource documentation. From @AndrewRayCode.
• #384 Improve the error.format() documentation. From @AndrewRayCode.
• #386 Ensure '*' as allowed-start-rule is documented for CLI. From @hildjj.

Minor cleanups

Minor Changes

• #329 Allow plugin options in
  generate. This change loosens type checking strictness to allow for options
  unknown to Peggy, but used by plugins such as ts-pegjs. From @hildjj.

Bug Fixes

• #329 Allow type definition for ParserBuildOptions to include plugin options. From @hildjj.
• #346 Allow extra semicolons between rules. From @hildjj.
• #347 Disallow '$' as an initial character in identifiers. This is not a breaking change because no grammar could have successfully used these in the past. From @hildjj.
• #354 Various minor nits in the docs, including indentation and ensuring that the CNAME file is correct.
• #357 Fix infinite recursion possibility in repetition delimeters. From @hildjj and @Mingun.
• #359 Do not treat as many words as reserved. Clarify the documentation about identifiers. Ensure that it is more clear that the target language being generated determines what words are reserved. Clarify that reserved word checking is only done for labels. From @nene.
• #364 Fix passing an incorrect external label to the expression inside the repeated node. From @Mingun.
