List of extractImplicitLexer() Examples

Examples of extractImplicitLexer()

org.antlr.v4.tool.GrammarTransformPipeline.extractImplicitLexer()
Build lexer grammar from combined grammar that looks like: (COMBINED_GRAMMAR A (tokens { X (= Y 'y')) (OPTIONS (= x 'y')) (@ members {foo}) (@ lexer header {package jj;}) (RULES (RULE .+))) Move rules and actions to new tree, don't dup. Split AST apart. We'll have this Grammar share token symbols later; don't generate tokenVocab or tokens{} section. Copy over named actions. Side-effects: it removes children from GRAMMAR & RULES nodes in combined AST. Anything cut out is dup'd before adding to lexer to avoid "who's ur daddy" issues

Examples of org.antlr.v4.tool.GrammarTransformPipeline.extractImplicitLexer()

    LexerGrammar lexerg;
    GrammarRootAST lexerAST;
    if ( g.ast!=null && g.ast.grammarType== ANTLRParser.COMBINED &&
       !g.ast.hasErrors )
    {
      lexerAST = transform.extractImplicitLexer(g); // alters g.ast
      if ( lexerAST!=null ) {
        if (grammarOptions != null) {
          lexerAST.cmdLineOptions = grammarOptions;
        }
