dot - ANTLR4 - DotGenerator example -


where can find example how use org.antlr.v4.tool.dotgenerator in antlr4?

as understand, replaces dottreegenerator in antlr4.

i interested in answer question , didn't find convincing 1 yet.

assuming interested in displaying parsetree here alternative way @ least visual representation:

  /**    * show given tree viewer    * @param tv    */ public int showtreeviewer(treeviewer tv) {   jpanel panel = new jpanel();   tv.setscale(2);   panel.add(tv);   return joptionpane.showconfirmdialog(null, panel, "parsetree",      joptionpane.ok_cancel_option, joptionpane.plain_message); }    // http://stackoverflow.com/questions/30134121/drawing-parse-tree-in-antlr4-using-java/30137407#30137407  parsetree tree=rulescontext;  list<string> rulenames=arrays.aslist(parser.getrulenames());  // http://stackoverflow.com/questions/34832518/antlr4-dotgenerator-example  treeviewer tv=new treeviewer(rulenames,tree);  showtreeviewer(tv);
