completion-nvim support

[ranjithshegde]

Does this feature exist in Emacs orgmode?

• [ ] Yes
• [ ] No
• [x] N/A

If answer to first question is "No", elaborate on how this feature is valuable and what problem does it solve. Using completion-nvim for autocompletion. Either by add this as a custom completion sources (similar to vimtex) or a direct integration.

If you could add steps to do so as a wiki or in README Thanks ...

Support for completion-nvim is added. Check https://github.com/kristijanhusak/orgmode.nvim#completion section.

Only limitation with completion-nvim is that it's not able to complete multiple tags. For example, if you have tags WORK and OFFICE, and having this content:

* TODO Some task :

It will suggest both tags in this case, but once you select one of them:

 TODO Some task :WORK:

It is no longer possible to complete any more tags because completion-nvim uses \k regex, which reads iskeyword. I added : to it in order to be able to complete tags and properties, but this breaks the multiple tags. Workaround is just to use omnifunc in these cases, because that properly autocompletes multiple tags.

@kristijanhusak Thank you For the problem you described, perhaps I could add omni as a custom source, chain it along for 'org' and enable auto_changing of the sources

[kristijanhusak]

@ranjithshegde yeah, something like that could work, I haven't tried it though.

[kristijanhusak]

@ranjithshegde Thanks, I just gave omni mode a try, and it works great. There's no need to add any special support for completion-nvim, just use omni mode:

vim.g.completion_chain_complete_list = {
  org = {
    { mode = 'omni'},
  },
}

@kristijanhusak I kind of prefer it to be more 'auto' than omni. meaning, without trigger characters omni only populates pumvisible with options beginning from the letter. For example it does not complete DEADLINE after : but only after :D

For now I have made a custom source from myself using require('orgmode.org.autocompletion').omni($) with appending to iskeyword with :,#,+ as you did in the relevant commit

[kristijanhusak]

@ranjithshegde you're right, adding those to iskeyword is necessary to make it work. I'll update the readme. Thanks.

Thanks @kristijanhusak. Earlier I was using completion-nvim only for LSPs so had to attach it to the buffer! Adding this works!

autocmd FileType org setlocal iskeyword+=:,#,+ |
            \ lua require'completion'.on_attach()
