Snyk has created this PR to upgrade pegjs from 0.9.0 to 0.10.0.
:information_source: Keep your dependencies up-to-date. This makes it easier to fix existing vulnerabilities and to more quickly identify and fix newly disclosed vulnerabilities when they affect your project.
The recommended version is 1 version ahead of your current version.
The recommended version was released 4 years ago, on 2016-08-19.
Parsers can be generated in multiple module formats. The available
formats are: CommonJS (the default), AMD, UMD, globals, and bare (not
available from the command-line).
The format can be specified using the format option of the peg.generate
function or the --format option on the command-line.
It is also possible to specify parser dependencies using the dependencies
option of the peg.generate function or the --dependency/-d option on
the command-line. This is mainly useful for the UMD format, where the
dependencies are translated into both AMD dependencies and CommonJS require calls.
Browser version of PEG.js is now in the UMD format. This means it will try
to detect AMD or Node.js/CommonJS module loader and define itself as a
module. If no loader is found, it will export itself using a global
variable.
API polishing. The peg.buildParser function was renamed to peg.generate. The global variable the browser version of PEG.js is
available in when no loader is detected was renamed from PEG to peg.
CLI improvements. There is new --output/-o command-line option which
allows to specify the output file. The old way of specifying the output file
using a second argument was removed. To make room for the new -o option
the old one (a shortcut for --optimize) was renamed to -O. All these
changes make PEG.js conform to traditional compiler command-line interface.
It is now also possible to use - as a file name on the command-line (with
the usual meaning of standard input/output).
Improved error messages. Both messages produced by PEG.js and generated
parsers were improved.
Duplicate rule definitions are reported as errors.
Duplicate labels are reported as errors.
Minor Changes
Exposed the AST node visitor builder as peg.compiler.visitor. This is
useful mainly for plugins which manipulate the AST.
Exposed the function which builds messages of exceptions produced by
generated parsers as SyntaxError.buildMessage. This is useful mainly for
customizing these error messages.
The error and expected functions now accept an optional location
parameter. This allows to customize the location in which the resulting
syntax error is reported.
Refactored expectations reported in the expected property of exceptions
produced by generated parsers. They are no longer de-duplicated and sorted,
their format changed to be more machine-readable, and they no longer contain
human-readable descriptions.
The found property of exceptions produced by the error function is now
set to null.
Removed access to the parser object in parser code via the parser
variable.
Made handling of optional parameters consistent with ES 2015. Specifically,
passing undefined as a parameter value is now equivalent to not passing
the parameter at all.
Renamed several compiler passes.
Generated parsers no longer consider \r, \u2028, and \u2029 as
newlines (only \n and \r\n).
Simplified the arithmetics example grammar.
Switched from first/rest to head/tail in PEG.js grammar and example
grammars.
Started using ESLint instead of JSHint and fixed various problems it found.
Tracing support. Parsers can be compiled with support for tracing their
progress, which can help debugging complex grammars. This feature is
experimental and is expected to evolve over time as experience is gained. More details
Infinite loop detection. Grammar constructs that could cause infinite
loops in generated parsers are detected during compilation and cause errors.
Improved location information API. The line, column, and offset
functions available in parser code were replaced by a single location
function which returns an object describing the current location. Similarly,
the line, column, and offset properties of exceptions were replaced by
a single location property. The location is no longer a single point but a
character range, which is meaningful mainly in actions where the range
covers action’s expression. More details
Improved error reporting. All exceptions thrown when generating a parser
have associated location information. And all exceptions thrown by generated
parser and PEG.js itself have a stack trace (the stack property) in
environments that support Error.captureStackTrace.
Strict mode code. All PEG.js and generated parser code is written using JavaScript strict mode.
Minor Changes
Labels behave like block-scoped variables. This means parser code can see
labels defined outside expressions containing code.
Empty sequences are no longer allowed.
Label names can’t be JavaScript reserved words.
Rule and label names can contain Unicode characters like in JavaScript.
Rules have to be separated either by ; or a newline (until now, any
whitespace was enough).
The PEG.js grammar and all the example grammars were completely rewritten.
This rewrite included a number of cleanups, formatting changes, naming
changes, and bug fixes.
The parser object can now be accessed as parser in parser code.
Location information computation is faster.
Added support for Node.js >= 0.10.x, io.js, and Edge. Removed support for
Node.js < 0.10.x.
Bug Fixes
Fixed left recursion detector which missed many cases.
Fixed escaping of U+0100—U+107F and U+1000—U+107F in generated code and
error messages.
Renamed parse and SyntaxError to peg$parse and peg$SyntaxError to
mark them as internal identifiers.
