[antlr-interest] Code completion, possible with JavaScript output?

[Andreas Stefik]

David,

This might not be an exact answer to your question, but the easiest
way I've found to do things like this is to read in the .tokens file
generated by antlr. For example, we do this to send keyword lists to
the NetBeans Platform for syntax highlighting, which works fine. I can
send a code example if necessary.

As for popping up a list for code completion, there are lots of ways
to do it. If you are using a rich client platform (e.g., eclipse,
netbeans), there are standard APIs for it, with corresponding
tutorials. Here is an example of one from NetBeans, for example:

http://platform.netbeans.org/tutorials/nbm-code-completion.html

So, basically, you read in the tokens file at bootup, you are
typically sent a position for where the cursor is in a file, then you
somehow decide, depending on what specifically you need and how far
you want to go with it, what words are populated in the list when the
user selects code completion.

Hope that helps,

Stefik
