Neovimのメモ

はじめに

普段は前のように Changelog(もはや Markdown) にメモしているがとりあえずまとめておこうと思い書いた。メモなので項目もバラバラで訳には立たない。

とりあえず init.vim

Fern の操作方法

現状では Space + e で開く。以下操作方法の一部

nvim coc で yarn install しろとか言われた場合

Neovim の coc があるフォルダ ~/.local/share/nvim/plugged/coc.nvim 以下などに行き coc フォルダへ移動してから以下のコマンドを実行する。

npx yarn install --frozen-lockfile

windows 用 Neovim

powershell で以下を実行

iwr -useb https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim | ni "$(@($env:XDG_DATA_HOME, $env:LOCALAPPDATA)[$null -eq $env:XDG_DATA_HOME])/nvim-data/site/autoload/plug.vim" -Force

mkdir %USERPROFILE%\AppData\Local\nvim

以下のファイルを編集する

~/AppData/Local/nvim/init.vim

call plug#begin(’~/.vim/plugged’)

フォント設定

~/AppData/Local/nvim/ginit.vim

Guifont! Cica:h18

以下を init.vim に書いても良い

set guifont=Cica:h18

pipenv 内での pylint

neovim で pylint が no module を返すときは pipenv install pylint をしていないため なので pipenv install pylint をそのフォルダ内で行うこと
