Deoplete is an asynchronous auto-completion plugin for Neovim, created by Shougo, aimed at improving completion without blocking Vim. It utilizes Python3 sources and offers several features to enhance the user experience, including better buffer source handling and the ability to support multiple languages. Future improvements for Deoplete include more customization options and the release of version 1.0, which will further enhance its capabilities.
deoplete: The dark powered auto completion plugin for neovim
- 1. deoplete ~ The dark powered auto completion plugin for neovim ~ Presented by Shougo
- 2. Introduction ● This slide is English for the foreign people ● But the talk is Japanese for the Japanese people ● The slide may contain spiritual topic or Chuunibyou( 厨二病 ) ● These are feature
- 3. Self-introduction ● Shougo ● I am called as “ 暗黒美夢王” . ● Pronounces it “Uncock Vim Awe”. ● Some people call me as “the sith lord of Vim plugins”. ● Text editor is all of my life ● My previous works: neocomplete, neobundle, neosnippet, unite, vimfiler, vimshell, etc...
- 4. Today's topic ● Deoplete plugin https://github.com/Shougo/deoplete.nvim ● It is the first asynchronous completion plugin for neovim ● You don't have to be annoying the completion blocks! ● If you don't know about neovim, please read my previous presentation. http://www.slideshare.net/Shougo/lets-talk-about- neovim
- 5. Why deoplete is created? ● My most concern is to block Vim in the completion ● if_lua is faster than VimL. But it also blocks ● Tarruda(neovim founder) said Wow!! Note: It is free translation
- 6. But ● The hell has been started from here...
- 7. Needed works (1/4) ● Python3 support – No if_lua support in neovim yet – I don't want to create new Python2 plugin in 2015 – I have added if_python3 feature based on if_python2 in neovim – Thanks the neovim reviewers!
- 8. Needed works (2/4) ● complete() bug fix – It is needed for deoplete, but it is not tested well – Thanks the vim-jp and neovim reviewers!
- 9. Needed works (3/4) ● v:completed_item and completeopt patches – It is needed for auto completion plugins – Thanks the vim-jp and neovim reviewers!
- 10. Needed works (4/4) ● Understand remote plugin features – Less documentation – Less examples – Hard to debug
- 11. Deoplete original features (1/3) ● Asynchronous call omnifunc – But the omnifunc which move cursors(side effect) is not supported – For example: htmlcomplete – Synchronous call omnifunc is also available like neocomplete
- 12. Deoplete original features (2/3) ● Python3 sources instead of VimL – You don't have to write VimL – You can wrap VimL functions in the source
- 13. Deoplete original features (3/3) ● Better buffer source – You don't have to know the line is cached if it is not large files – The lines are analyzed like built-in buffer completion – You must wait to complete in editing large files, but it is non blocking!
- 14. Sources ● Built-in – buffer, tag, file, omni, member, dictionary ● External – Neco-ghc, neosnippet, neco- look, neco-vim, neco-syntax, vim-racer, vimshell
- 15. Installation 1.Clone Deoplete source $ git clone https://github.com/Shougo/deoplete.nvim 2.Install neovim $ git clone https://github.com/neovim/neovim 3.Install neovim-python3 $ (sudo) pip3 install neovim
- 16. Demo ● Edit eval.c (22000 lines) with deoplete + neovim ● Edit eval.c (22000 lines) with neocomplete + Vim ● “Behold Vimmers, this is THE real asynchronous!”
- 17. FAQ (1) ● Is Deoplete is faster than neocomplete? ● I think neocomplete is faster because of if_lua power ● The asynchronous is to skip the completion if your input is too fast ● So, you should use deoplete in newer machine
- 18. FAQ (2) ● Deoplete does support any of languages? ● Deoplete can call omnifunc automatically ● Or you can create the source for it ● Why don't you create the source? ● :help deoplete-create-source
- 19. In the future ● Deoplete version 1.0 will be released after the presentation! ● After version 1.0: – More customization – Improve file source behavior – Implement more features in neocomplete ● Rewrite unite.vim for neovim(VimConf2016 presentation)
- 20. Fin ● If you think “Deoplete is nice!”, please support neovim project by money or code. https://salt.bountysource.com/teams/neovi m https://github.com/neovim/neovim/issues ● Deoplete depends on the neovim's features!
