Don't autocomplete if phrase starts with backtick

[Ryan J Ollos]

In #12118 I was typing:

Please post your [ticket-workflow] section.

After typing `[ the auto-complete appears, but probably shouldn't for this case.

[Peter Suter]

I think we could prevent auto-completions after `[ like this:

wikiautocomplete/htdocs/js/wikiautocomplete.js

         },
 
         { // TracLinks, InterTrac and InterWiki
-            match: /(^|[^[])\[(\w*)$/,
+            match: /(^|[^[`])\[(\w*)$/,
             search: search_cache('linkresolvers', function(resolver, term) {
                 return match_string(resolver.name, term);
             }),

Would you also prevent other cases like `wiki:? Or not prevent auto-completions after closing backquote like `quoted`[? I don't see an obvious need.

I think ideally we would also prevent auto-completions inside {{{ / }}}, but it's not obvious to me how to best achieve this.

Replying to psuter:

Yeah, looks good.

I agree that it's probably not needed.

Also, not sure if this is practical, but it would be nice to avoid auto-completing with local resources when typing an InterTrac prefix, e.g. trac:#, t:wiki:.

[Peter Suter]

A better approach might be to use a context function​ that removes `quoted` strings and {{{ ... }}} blocks before attempting to match.

Only the {{{#!... preprocessor completions should not use that. Unfortunately there seems to be a ​bug in jquery-textcomplete, but it might be possible to workaround it by handling the preprocessors first.

[Peter Suter]

In 16270:

WikiAutoCompletePlugin: Don't autocomplete in quoted parts.

Don't use context function for "Processors" strategy.
Move "Processors" strategy up first, to avoid bug in jquery-textcomplete.

Thanks, I've updated plugin on trac-hacks.org.

Do you have any thoughts about this one? Should I create a different ticket?

Thanks for reminding me. I now created #13090.
