reflection library

This package contains tools to reflect on and transform parsers.

Classes

Analyzer

Helper to reflect on properties of a grammar.

LinterIssue

Encapsulates a single linter issue.

LinterRule

Encapsulates a single linter rule.

Enums

LinterType

The type of a linter issue.

Constants

allLinterRules → const List<LinterRule>

All default linter rules to be run.

Functions

allParser(Parser root) → Iterable<Parser>

Returns a lazy iterable over all parsers reachable from root using a depth-first traversal over the connected parser graph.

linter(Parser parser, {LinterCallback? callback, List<LinterRule>? rules, Set<String> excludedRules = const {}, Set<LinterType> excludedTypes = const {LinterType.info}}) → List<LinterIssue>

Returns a list of linter issues found when analyzing the parser graph reachable from parser.

removeDuplicates<T>(Parser<T> parser) → Parser<T>

Returns a copy of parser with all duplicates parsers collapsed.

removeSettables<T>(Parser<T> parser) → Parser<T>

Returns a copy of parser with all settable parsers removed.

transformParser<T>(Parser<T> parser, TransformationHandler handler) → Parser<T>

Transforms all parsers reachable from parser with the given handler. The identity function returns a copy of the the incoming parser.

Typedefs

LinterCallback = void Function(LinterIssue issue)

Function signature of a linter callback that is called whenever a linter rule identifies an issue.

TransformationHandler = Parser<T> Function<T>(Parser<T> parser)

A function transforming one parser to another one.
