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

[* 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

[* 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
