[gedit-list] GtkSourceView

In the last days I made a color and syntax scheme for Nim language.

Generally its was working really fine, and the documentation is also
fine.

For final tuning I tried to use regexes like this:

<!-- Nim identifier, maybe enclosed in ``, starting lower or upper case -->
<define-regex id="nid">(?'a'`?)[a-zA-Z]\w*(\k'a')</define-regex>

That gave me a lot trouble. Is it a known problem that regexes with
back references are problematic? Or is there maybe a better working
notation available? Unnamed back reference with \1 seems to do not work
at all. Of course I can avoid back references when I do use too ored
regexes, one with `` and one without.


To make the scheme more flexible, I tried to apply regexes like

<define-regex id="ind">\s\s</define-regex>

at some locations where I previously used two /s/s or two spaces, but
it was not really working.

One example is

<context id="indent-pat4" style-ref="indent">
<!-- this seems not to work, why?
<match>(?&lt;=(^\w{ind}))(\w{ind})</match>
-->
<match>(?&lt;=(^  ))(  )</match>
</context>

My assumption was that it should behave the same.

Last remark: Highlight unmatched bracket seems not to work at all for
GTK 3.18.
