Hi, I'm newbie using Antlr3.Runtime.dll C# , VS 2008, CSharp2 target (perhaps better use vs2010 and CSharp3 target)
I need advanced error handling for use spanish in my error messages, and do more clearly the messages to show it to the users. I have been this page: http://www.antlr.org/wiki/pages/viewpage.action?pageId=23232568 how is the code of getRuleInvocationStack ??? please, any another advanced samples for error handling ?? thanks. public String getErrorMessage(RecognitionException e, String[] tokenNames) { List stack = getRuleInvocationStack(e, this.getClass().getName()); String msg = null; String inputContext = input.LT(-3) == null ? "" : ((Tree)input.LT(-3)).getText()+" "+ input.LT(-2) == null ? "" : ((Tree)input.LT(-2)).getText()+" "+ input.LT(-1) == null ? "" : ((Tree)input.LT(-1)).getText()+" >>>"+ ((Tree)input.LT(1)).getText()+"<<< "+ ((Tree)input.LT(2)).getText()+" "+ ((Tree)input.LT(3)).getText(); if ( e instanceof NoViableAltException ) { NoViableAltException nvae = (NoViableAltException)e; msg = " no viable alt; token="+e.token+ " (decision="+nvae.decisionNumber+ " state "+nvae.stateNumber+")"+ " decision=<<"+nvae.grammarDecisionDescription+">>"; } else { msg = super.getErrorMessage(e, tokenNames); } return stack+" "+msg+" context=..."+inputContext+"..."; } public String getTokenErrorDisplay(Token t) { return t.toString(); } List: http://www.antlr.org/mailman/listinfo/antlr-interest Unsubscribe: http://www.antlr.org/mailman/options/antlr-interest/your-email-address -- You received this message because you are subscribed to the Google Groups "il-antlr-interest" group.
