Example 1 with InstanceScope

use of org.stringtemplate.v4.InstanceScope in project antlr4 by antlr.

the class TestCodeGeneration method getEvalInfoForString.

public List<String> getEvalInfoForString(String grammarString, String pattern) throws RecognitionException {
    ErrorQueue equeue = new ErrorQueue();
    Grammar g = new Grammar(grammarString);
    List<String> evals = new ArrayList<String>();

        if (g.isLexer())
            factory = new LexerATNFactory((LexerGrammar) g);
        g.atn = factory.createATN();
        CodeGenerator gen = new CodeGenerator(g);
        ST outputFileST = gen.generateParser();
        //			STViz viz = outputFileST.inspect();
        //			try {
        //				viz.waitForClose();
        //			}
        //			catch (Exception e) {
        //				e.printStackTrace();
        //			}
        boolean debug = false;
        DebugInterpreter interp = new DebugInterpreter(outputFileST.groupThatCreatedThisInstance, outputFileST.impl.nativeGroup.errMgr, debug);
        InstanceScope scope = new InstanceScope(null, outputFileST);
        StringWriter sw = new StringWriter();
        AutoIndentWriter out = new AutoIndentWriter(sw);
        interp.exec(out, scope);
        for (String e : interp.evals) {
            if (e.contains(pattern)) {
                evals.add(e);
            }
        }
    }
    if (equeue.size() > 0) {
        System.err.println(equeue.toString());
    }
    return evals;
}

Example 2 with InstanceScope

use of org.stringtemplate.v4.InstanceScope in project bndtools by bndtools.

    Interpreter interpreter = new Interpreter(st.groupThatCreatedThisInstance, Locale.getDefault(), true) {

        @Override
        public Object getAttribute(InstanceScope scope, String name) {
            attrs.put(name, null);
