安裝好用的文字編輯工具 — LunarVim

大家好，祝福大家都可以睡得很好。

今天來跟大家講講怎麼在 Ubuntu 上安裝 LunarVim 這個好工具，以及它其他好用的套件。它是一個基於 NeoVim 的 IDE，除了基本 Vim 的功能以外，它也集成了很多好用的設定及插件。

由於 APT 庫裡面的 NeoVim 並不是最新的穩定版本，所以我們需要使用別的方法來安裝 NeoVim。

我的安裝策略是這樣的：

rsvm => Rust 1.78.0 => Bob => NeoVim v0.9.5

首先，我們先打開終端機，用 curl 指令安裝 rsvm，rsvm 是 Rust 的版本管理工具，安裝後，可以任意切換 Rust 版本：

curl -L https://raw.github.com/sdepold/rsvm/master/install.sh | bash

使用 rsvm 來安裝並套用最新穩定版本的 Rust：

rsvm install 1.78.0
rsvm use 1.78.0

使用 Cargo 工具來安裝 Bob，Bob 是一個 NeoVim 的版本管理工具：

cargo install bob-nvim

使用 Bob 安裝 NeoVim v0.9.5：

bob install stable
bob use stable

執行完後，可以看看 NeoVim 的版本是否正確：

nvim --version

如果確認 NeoVim 安裝成功，而且版本是 0.9.5 以上的話，我們就可以開始安裝 LunarVim 了，在終端機中輸入以下指令：

LV_BRANCH='release-1.4/neovim-0.9' bash <(curl -s https://raw.githubusercontent.com/LunarVim/LunarVim/release-1.4/neovim-0.9/utils/installer/install.sh)

LunarVim 安裝完成後，在終端機中輸入 lvim ，即可打開 LunarVim。

LunarVim 的設定檔預設會被放在 ~/.config/lvim 中，如果想要安裝插件的話，可以編輯 config.lua 這個檔案。如果你不知道該怎麼做的話，可以參考我的設定：

儲存後再次使用 lvim 打開 LunarVim，就會自動重載 config.lua 當中的插件了。
