Cannot get completion to work

[iexos]

Description

I want to use the completion to find pages and cannot get it to work. I boiled it down to the absolut minimum, what am I missing?

• vim -u ~/junkyard/init.vim ~/junkyard/index.md
• start typing tes (or [tes or [x](tes,...) and press C-X C-O
• expecting completion for test.md but nothing happens

Notes

• :WikiPages, <cr> and other functionality works as expected
• C-X C-O works for e.g. python with this init.vim
• :verbose set omnifunc?: omnifunc=wiki#complete#omnicomplete Last set from ~/.local/share/nvim/plugged/wiki.vim/autoload/wiki/buffer.vim line 11

Minimal working example

Files:

$ ls ~/junkyard/wiki
index.md  test.md

neovim: NVIM v0.9.0

minimal init.vim:

let &rtp  = '~/.local/share/nvim/plugged/wiki.vim,' . &rtp
let g:wiki_root = '~/junkyard/wiki'

I want to use the completion to find pages and cannot get it to work. I boiled it down to the absolut minimum, what am I missing?

Thanks, this is a very good minimal example! Here are some adjustments to simplify:

• Create test folder:

  mkdir ~/test
  cd ~/test
  touch {index,foo,bar}.md

• Create test.vim:

  let &rtp  = '~/.local/share/nvim/plugged/wiki.vim,' . &rtp

• Use nvim --clean -u test.vim index.md to start neovim

• Type [test]( then <c-x><c-o> and it should complete as expected. This works on my end.

The main change here is that we removed the global g:wiki_journal. I believe it is not really relevant here. Does the above work for you?

Thank you for the instructions! No, I just get

That's strange. Which OS are you on? Which version of wiki.vim? If you are not on the latest version, then please update.

After following the steps outlined in my previuos comment, please do this and report the output:

cd ~/test
pwd   # does your $HOME have strange characters?
ls -l # or tree if you have it
cat test.vim
cat index.md

Next, do nvim --clean -u test.vim index.md and report the output of:

• :echo b:wiki
• :echo &omnifunc

[iexos]

I'm on a current Arch Linux

$ cd ~/.local/share/nvim/plugged/wiki.vim
$ git rev-parse HEAD
f9769a61bfb70ba0801b79174ed7f2f4d31fdf83
$ cd ~/test
$ pwd
/home/holger/test
$ ls -l
-rw-r--r-- 1 holger holger  0 May 25 09:39 bar.md
-rw-r--r-- 1 holger holger  0 May 25 09:39 foo.md
-rw-r--r-- 1 holger holger  0 May 25 09:39 index.md
-rw-r--r-- 1 holger holger 59 May 25 09:39 test.vim
$ nvim --clean -u test.vim index.md
$$ :echo b:wiki
{'root': '/home/holger/test', 'in_journal': 0, 'index_name': 'index', 'extension': 'md'}
$$ :echo &omnifunc
wiki#complete#omnicomplete

[lervag]

Please also cat test.vim.

[lervag]

But, it seems things look correct. I want to see cat test.vim just to be 100% sure there is no surprise misunderstanding.

The next step is to continue the steps earlier defined steps. After nvim --clean -u test.vim index.md, write [text here]( and then <c-x><c-o> - does it still say "Pattern not found"? (I assume it does, since we did not change anything yet.)

Now, perhaps can we do some simple print debugging together. Let's start here:

wiki.vim/autoload/wiki/complete.vim

Lines 138 to 139 in f9769a6

	let l:cnum = match(a:line, '\](\zs[^)]\{-}$')
	if l:cnum < 0 | return -1 | endif

Add a line unsilent echom "DEBUG HERE" l:cnum before line 139; repeat the test. What is the output? You might need to do :messages to see the message after you get "Pattern not found".

I would expect l:cnum to be a positive number. If it is, then the next position we want to inspect is here:

wiki.vim/autoload/wiki/complete.vim

Lines 89 to 93 in f9769a6

	let l:candidates = self.is_anchor
	\ ? self.complete_anchor(a:regex)
	\ : self.complete_page(a:regex)
	return map(l:candidates, "{'word': v:val, 'menu': '[wiki]'}")

Ok, I debugged a bit further and found that fd tries to be smart by reading the .gitignore in my home dir which excludes everything but a few versioned config files. Simply replacing fd with fd -I makes completion work.

Oh, I did not think of that. Thanks! I'll push an update immediately!

[lervag]

Let me know if this fixes it for you. If not, feel free to reopen!

[iexos]

Fix works, thank you!

Great, glad to hear it! Thanks for digging in and noticing the issue!
