Very nice, thanks for the proof of concept and example function! I'll consider adding this 👍

For some reason it hangs at the begining. I thinkcontext doesn't like to to start with a indent level of 5 on an empty file ....

Yes,indent() returns -1 for invalid lines, for example tryecho indent(0). This is used as exit condition incontext#popup#get_context() for example. So you could probably fix that by making your custom function have that property too. So for example like this maybe (untested):

functionMyIndent(line)letindent=indent(a:line)ifindent <0return [indent,indent]endifletline=getline(a:line)let headings=match(line,'^*\+\zs\s')+1if headings<=0let headings=match(line,'^#\+\zs\s')+1if headings<=0let headings=5endifendifreturn [indent+headings,indent]endfunctionletg:Context_indent_function=funcref("MyIndent")letg:context_skip_regex='^\s*$'

Edit: Updated according to changes introduced in#85.

Your modification works perfectly. Thanks.

Hey, thanks again! I tried using this branch for a bit and I found one fundamental issue I don't have a good idea yet how we can solve it in a clean way. Have a look at this screenshot:

Because of the+5 in the example indent function from above the border line (▬▬▬▬▬▬ <context.vim>) is indented five characters too much. Do you see a good way to fix that?

I guess the indentation of the border line is a feature (which I didn't realize was there until now).
An option would be obviously to add a global variable to enable/disable it (or have an offset ?)
However, I'm not really happy with the +5 either, it would probably best to be able to specify a special level of indentation (-1, 999, a string ) which mean this line is never part of a context.

I've pushed a new version ...

Thank you! To be honest I also have some concerns* about the new implementation. Let me think about it some more.

*Now we always evaluate the border line indent thing, even though we almost never use. That seems a bit wasteful IMO.

@maxigit: I picked your first commit and then added some more to add a separate setting for the border indent function. I opened a new PR:#54

Would you have a look at that and let me know if that works for you and makes sense? Thank you!

Seems to work. However, to make it work I add to dolet g:context_skip_regex = '^\s*$'.
Which is then line pased to border_line, is the last line of the popup or the first line after the popup ?

@maxigit: Thanks for checking! I mentioned that in the README and updated the linked comment 👍

Do you think it's clear enough now?

Thank you for the feedback, will merge it later 👍

The reason you need to update the skip regex is that the default one does skip lines starting with#. I did this because in many file formats those lines are comments and I wanted to exclude comment lines from the context. So in order to include markdown header lines (which start with#) we need to not skip those lines, hence a different skip regex is required.

Added in#54.
