Conceal Patch / MacVim

[Nicholas Cole]

Dear All,

Has anyone managed to build MacVim with Vince Negri's Conceal patch

( http://sites.google.com/site/vincenegri/ )

applied?

Oh, how I wish it was part of standard vim. But since it
isn't.....I've tried to apply it and failed. Has anyone succeeded?

Best wishes,

Nicholas

I couldn't apply it to my repository as I'm at patch level 411,
Vince's patch is against patch-level 141.
If Vince wants to merge to trunk, I'll make a build.

BTW: What does it do?

It lets you fold within lines as well as whole lines, so that you can
hide part of a line....very useful for things like LaTeX editing.

I'm afraid I didn't quite follow the 411 / 141 distinction....

Best wishes,

Oh, sorry. Version numbers....

It's a bit complex to quickly explain but the idea is to have
two views on the same file where one view shows all the markup
details of a LaTeX file, while the other view shows just the
text that will be visible when the code is rendered to a printed
page. It provides three unrelated features:
'cursorbind' : move cursor in both windows when scrolling
'conceal' : replace or hide text matching a pattern
:ownsyntax : buffer has different syntax rules in each window

There is some info here:
http://sites.google.com/site/vincenegri/concealownsyntaxforvim
http://vim.wikia.com/wiki/Patch_to_conceal_parts_of_lines

The latter is out of date (but the intro still applies).

I tried late last December. At the time, the latest Vim was
7.2.323 and after quite a bit of trouble I modified Vince's
patch (which is based on Vim 7.2.141) so I got a successful
build (and I carefully checked that I had not broken the patch).

In testing, it seemed to work (I was interested mainly in
cursorbind because Vim's scrollbind is extremely irritating
under certain conditions when doing a diff).

However, when I used the patched Vim with tab pages (not using
any of the Conceal patch features), the patched Vim would
frequently crash.

Following is the last note that I wrote while testing:
OMG looks like following is enough to crash:
gvim -N -u NONE
:tabnew
:syn off

The issue is still on my todo list. I was thinking of updating
the patch to apply it with the current Vim version, then
emailing Vince and asking for help (I have looked at the code
and it is extremely complex). I should mention that I do not use
a Mac (I scan this list only because I am one of the managers
who approve new members in order to avoid spam).

Dear John,

Thank you for the information and the warning! It really would be
fantastic to have a version of this that worked with a modern vim,
although I do appreciate that this seems to be something of a niche
requirement (I've used it in the past to make editing very large LaTeX
projects less painful). So thank you in advance for whenever it makes
it to the top of your To-Do list!

Best wishes,

Nicholas
