This plugin simplifies automation of generating lexers and parsers for IntelliJ plugins.
NB: plugin does not support two-pass generation, therefore does not suport method mixins.

Global configuration allows you to select necessary jFlex and Grammar-Kit versions.

// version of IntelliJ patched JFlex (see the link below), Default is 1.7.0-1
jflexRelease = '1.7.0-1'
// tag or short commit hash of Grammar-Kit to use (see link below). Default is 2020.3.1
grammarKitRelease = '6452fde524'
// optionally provide an IntelliJ version to build the classpath for GenerateParser/GenerateLexer tasks
intellijRelease = '203.7717.81'
}

targetDir = "gen/com/perl5/lang/perl/lexer/"
// target classname, target file will be targetDir/targetClass.java

// optional, path to the task-specific skeleton file. Default: none

// if set, plugin will remove a lexer output file before generating new one. Default: false

// if set, plugin will remove a parser output file and psi output directory before generating new ones. Default: false
