Examples of org.stringtemplate.v4.AutoIndentWriter

org.stringtemplate.v4.STGroupFile
Essentially a char filter that knows how to auto-indent output by maintaining a stack of indent levels. The indent stack is a stack of strings so we can repeat original indent not just the same number of columns (don't have to worry about tabs vs spaces then). Anchors are char positions (tabs won't work) that indicate where all future wraps should justify to. The wrap position is actually the larger of either the last anchor or the indentation level. This is a filter on a Writer. \n is the proper way to say newline for options and templates. Templates can mix \r\n and \n them but use \n for sure in options like wrap="\n". ST will generate the right thing. Override the default (locale) newline by passing in a string to the constructor.

    // error information possible, but actually writing output files stops
    // after the first error is reported
    int errorCount = g.tool.errMgr.getNumErrors();


    if ( g.isLexer() ) {
      ST lexer = gen.generateLexer();
      if (g.tool.errMgr.getNumErrors() == errorCount) {
        writeRecognizer(lexer, gen);
      }
    }
    else {
      ST parser = gen.generateParser();
      if (g.tool.errMgr.getNumErrors() == errorCount) {
        writeRecognizer(parser, gen);
      }
      if ( g.tool.gen_listener ) {
        ST listener = gen.generateListener();
        if (g.tool.errMgr.getNumErrors() == errorCount) {
          gen.writeListener(listener);
        }
        if (gen.getTarget().wantsBaseListener()) {
          ST baseListener = gen.generateBaseListener();
          if (g.tool.errMgr.getNumErrors() == errorCount) {
            gen.writeBaseListener(baseListener);
          }
        }
      }
      if ( g.tool.gen_visitor ) {
        ST visitor = gen.generateVisitor();
        if (g.tool.errMgr.getNumErrors() == errorCount) {
          gen.writeVisitor(visitor);
        }
        if (gen.getTarget().wantsBaseVisitor()) {
          ST baseVisitor = gen.generateBaseVisitor();
          if (g.tool.errMgr.getNumErrors() == errorCount) {
