Vimメモ

2021/07/02 に Release された nvim-0.5 で、 LanguageServer と DebugAdapter を設定する方法を中心に情報を収集する。

packer

install

luarocks

packer で use_rocks もしくは rocks を記述すると、 hererocks によるがインストールされる。

use_rocks "penlight"

-- もしくは
use { 
	"some",
	rocks = {
		{"penlight"},
	}
}

場所は、 nvim.fn.stdpath "cache" 下。

  • ~/.cache/nvim/hererocks
  • %USERPROFILE%/AppData/Local/temp/nvim/hererocks

で Windows では hererocks が失敗するということが分かった。 Linux 版の hererocks の構成は以下の通り。

%USERPROFILE%/Local/nvim-data/site/pack/packer/start/packer.nvim/lua/pcker/luarocks.lua が Windows 動くように改造

local function activate_hererocks_cmd(install_path)
  local activate_file = 'activate'
  local user_shell = os.getenv 'SHELL'
  local shell = user_shell:gmatch '([^/]*)$'()
  if shell == 'fish' then

  elseif shell == 'csh' then
    activate_file = 'activate.csh'
  end

  return fmt('source %s', util.join_paths(install_path, 'bin', activate_file))
end

local function hererocks_cmd(install_path, args)
  if vim.fn.has('win32') ~= 0 then
	-- これで %USERPROFILE%/AppData/Local/temp/nvim/hererocks/2.1.0-beta3/luarocks.bat を呼び出す
    return {

      fmt('%s && luarocks --tree=%s %s', activate_hererocks_cmd(install_path), shell_hererocks_dir, args),
    }
  end
end

local function run_luarocks(args, disp, operation_name)
  local cmd =hererocks_cmd(hererocks_install_dir, args)

%USERPROFILE%/AppData/Local/temp/nvim/hererocks に luarocks を展開する。 neovim のビルドに使った luarocks をコピーする。

LanguageServer(nvim built-in)

neovim-0.5 から組み込みの LSP-Client 機能が実装される。

https://neovim.io/doc/user/lsp.html

各言語ごとの LanguageServer の自動起動などを担うのが lspconfig。

pylsp を選択した。型対応があって pyright が強そうなのだけど。

http://vimdoc.sourceforge.net/htmldoc/version7.html#new-omni-completion https://vim.fandom.com/wiki/Omni_completion https://vim.fandom.com/wiki/Omni_completion_popup_menu

インテリセンスみたいな文脈を考慮した補完。素の completion とのインターフェース上の違いは？

code:.vim filetype plugin on set omnifunc=syntaxcomplete#Complete

<C-X><C-O> while open in Insert mode

[* vim-lsp] https://qiita.com/yami_beta/items/1bb1341113e12bcfb1b8

[* 補完関数の実装] [Vim の complete-functions でハマった http://d.hatena.ne.jp/osyo-manga/20140806/1407291600]

[* 補完の呼び出し] vimに以下の種類の挿入モード補完がある Whole lines |i_CTRL-X_CTRL-L| keywords in the current file |i_CTRL-X_CTRL-N| keywords in 'dictionary' |i_CTRL-X_CTRL-K| keywords in 'thesaurus', thesaurus-style |i_CTRL-X_CTRL-T| keywords in the current and included files |i_CTRL-X_CTRL-I| tags |i_CTRL-X_CTRL-]| file names |i_CTRL-X_CTRL-F| definitions or macros |i_CTRL-X_CTRL-D| Vim command-line |i_CTRL-X_CTRL-V| User defined completion |i_CTRL-X_CTRL-U| omni completion |i_CTRL-X_CTRL-O| Spelling suggestions |i_CTRL-X_s| keywords in 'complete' |i_CTRL-N| |i_CTRL-P| これしか使ってなかった

https://www.xmisao.com/2014/05/04/vim-completefunc.html https://github.com/neoclide/coc.nvim

[* 起動方法で異なる補完が出る]

File completion: Line completion: Omni completion:

どの補完を使うか考えずに使いたい

deoplete 複数のソースを統合する。強い
一方で十分な量のバッファが開かれていればの `C-n` `C-p` で十分強い。むしろこれより弱くしたくない。

[* complete] set complete=.,w,b,u,t

[* completeopt] set completeopt+=menu,preview

[* pumvisible] pumvisible() pop up menu のことらしい

code:.vim inoremap pumvisible() ? "<C-e>" : "<Esc>" inoremap pumvisible() ? "<C-y>" : "<CR>" inoremap pumvisible() ? "<C-n>" : "<Down>" inoremap pumvisible() ? "<C-p>" : "<Up>" inoremap pumvisible() ? "<PageDown><C-p><C-n>" : "<PageDown>" inoremap pumvisible() ? "<PageUp><C-p><C-n>" : "<PageUp>"

[* keyword] C-N, C-P help i^n, i^p

[* 対象を自動で振り分ける例] https://vim.fandom.com/wiki/Smart_mapping_for_tab_completion

code:.vim function! Smart_TabComplete() let line = getline('.') " current line

let substr = strpart(line, -1, col('.')+1) " from the start of the current " line to one character right " of the cursor let substr = matchstr(substr, "1*$") " word till cursor if (strlen(substr)==0) " nothing to match on empty string return "<tab>" endif let has_period = match(substr, '.') != -1 " position of period, if any let has_slash = match(substr, '/') != -1 " position of slash, if any if (!has_period && !has_slash) return "<C-X><C-P>" " existing text matching elseif ( has_slash ) return "<C-X><C-F>" " file matching else return "<C-X><C-O>" " plugin matching endif endfunction
