[antlr-interest] Highlighting syntax errors

[Sam Harwell]

All Visual Studio language service features run on separate threads from the main UI thread. I have several posts on my blog (http://blog.280z28.org/) talking about ANTLR/Visual Studio integration for language services. If you are interested, I could probably add articles on the following:

 

·         Ensuring your language service doesn’t slow down the IDE (like Eclipse does, for example)

·         Highlighting errors in the IDE. This is supported in the Managed Babel framework and is relatively easy to add to an ANTLR language service. All of my language services, including the ones for nFringe, support this feature.

Hi,

When I parse an input in ANTLRWorks IDE, I can see which portion of the input has errors using the 'input' window in the debugger. Syntax error (handled by automatic error recovery) will be highlighted in red. While this is a very useful feature, I cannot parse a very big file (approx 1 mb) inside the IDE as that would be very slow. Is there a way to do this "error highlighting" outside the IDE using the error handling techniques? I looked into chapter 10. But didn't get any hint.

Advanced thanks for any pointers :-)
