Conceal of wiki links results in long chunks of empty space

[arisolt]

In the following example:

This is a [[/path/to/file|link]].

When toggling set conceallevel=2, the result is:

This is a                 link.

What is notable is that the ]] after link is concealed correctly (i.e it disappears and the fullstop shifts position). However, the portion before link is replaced by a long chunk of space. Why is this happening? Could it be because of something in my environment, or is it expected behaviour?

That's very strange. On my end, the conceal works as expected. It would be very helpful if you created a minimal example vimrc file, something like this:

set nocompatible
set runtimepath^=~/.local/plugged/wiki.vim
set runtimepath^=~/.local/plugged/wiki-ft.vim
filetype plugin indent on
syntax enable

set conceallevel=2
let g:wiki_root = "..."
" ... other relevant options

If you save the above listing to test.vim and run vim -u test.vim or nvim --clean -u test.vim (if you use neovim), then you should have a minimal environment. You can open a wiki file and test if the issue persists.

Hmm yes, with a minimal .vimrc it does conceal correctly. I'll need to dig into my configured environment and see what's causing it. Thanks!

Ok, it looks like what I was experiencing is actually another issue related to vim's poor implementation of soft wrapping: https://github.com/vim/vim/issues/260#issuecomment-905219351

That does make sense. I am aware of issues with soft wrapping and conceals, but I've never seen this issue lead to the empty space in front; also, I've never had an issue unless the line is actually long enough for there to be soft wrapping.
