Slow on large file (cursor lag)
Hi,
I have noticed the duplicated Issues: #107 #494 and #527 . But I don't think the problem has been solved.
-
tagbar
works fine inneovim
andvim
with small file (<1k loc) -
tagbar
works fine invim
with big file (>2k loc) bug not works fine inneovim
(cursor lag) - Previous version of
tagbar
works fine inneovim
with big file (eg. chxuan/tagbar, which is an archive oftagbar
v2.3) - Other plugins using
ctags
such as liuchengxu/vista.vim don't have similar problem.
tagbar
v2.3 is a long history, but I still hope if someone can check where the problem is.
Anyway, tagbar
was the first plugin I started with vim and it is an amazing project, thanks for your work!
PS: I'm running vim
9.0 (updatetime 4000) and nvim
v0.8.1 (updatetime 250).
We have tried various methods to have tagbar run as a background task, but so far we haven't been successful in getting it to function seamlessly. There was a PR a while back that added the g:tagbar_file_size_limit
option to not run tagbar on file sizes that are too large.
PRs are always welcome if someone has any expertise in the matter, but I don't have that expertise or frankly the time to rework much of this plugin at this time. I jumped in as a user of tagbar and started to help out adding smaller features and fixing bugs that I can, but this has been more of a side project that I've been able to spend time on as I have it.
So unfortunately we don't really have a good fix for this at this time. As I said though, PRs are welcome. I'll leave this issue open for the time being incase anyone with more expertise in the matter has time and the inclination to address it, but I fear we may be out of luck for this one for the time being.

Agree, that's too sad.
Maybe a rewrite of tagbar
in LUA could help? A tagbar.nvim
plugin.
Anyway, I also confirm the laggy cursor movements when running tagbar
on big files.
Unfortunately, after running tagbar
on a big file, this lag persists even switching to a small buffer, even if tagbar
is not run in it, and I'm forced restarting Neovim.
Tested with Neovim v0.8.3 stable, on Windows 10.
