使用 LunarVim¶
lunarvim 的主要作者已经不更新了。这个项目基本寄了。下文是之前写的, 权且留作纪念
之前配置 vim 的方案是 nvim + vim-plug, 但使用一段时间之后发现了更简便的做法: 直接使用 LunarVim !
LunarVim 的好处是开箱即用, 而且定义插件和快捷键都很方便, 很适合在个人电脑上使用。
如果是在无法翻墙的环境安装，需要把安装命令中的 githubusercontent 替换为 gitmirror，比如
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)
# 改为
LV_BRANCH='release-1.4/neovim-0.9' bash <(curl -s https://raw.gitmirror.com/LunarVim/LunarVim/release-1.4/neovim-0.9/utils/installer/install.sh)
目前在 ~/.config/lvim/config.lua 中的配置:

问题整合¶
LSP 不工作, gd 没反应¶
首先，看下 :LspInfo，不工作的情况是这样的:
Detected filetype: cpp
0 client(s) attached to this buffer:
Configured servers list:
然后, 尝试运行: :LvimCacheReset
gentoo 更新后lvim吞字符¶
gentoo 服务器更新后，发现文本对齐后的第一个字符都不显示（如下图），我的 wsl (ubuntu) 和另一台 arch 系统的电脑都没这个问题。
同时报很多错,
An internal error has occured: false ".../lazy/opt/nvim-treesitter/lua/nvim-treesitter/locals.lua:286: attempt to call method 'parent' (a nil value)"
:checkhealth nvim-treesitter
得到:

查找各方论坛无果，一方面是围绕 treesitter 解决问题，但即使是直接禁用 :TSDisable 都没有用。还有很多其它无效的尝试，令人抓狂。
最后，试出来的解决方法是，自己下载 nvim 的 appimage, 然后把 appimage 的路径添加到 $PATH 中，
~/.config/nvim/executable/
不用系统自带的 nvim 可以解决吞字符的问题。虽然还是报一些错：
An internal error has occured: false ".../lazy/opt/nvim-treesitter/lua/nvim-treesitter/locals.lua:286: attempt to call method 'parent' (a nil value)"
以及需要把配置中的自动保存折叠信息全注释掉lvim 才能勉强工作（否则移动一下光标就会自动折叠所有代码）
-- 自动保存折叠信息
--vim.api.nvim_create_autocmd({ "BufWinLeave" }, {
-- pattern = { "*.*" },
-- desc = "save view (folds), when closing file",
-- command = "mkview",
--})
--vim.api.nvim_create_autocmd({ "BufWinEnter" }, {
-- pattern = { "*.*" },
-- desc = "load view (folds), when opening file",
-- command = "silent! loadview"
--})
没排查出来问题的原因，只是试出来初步的解决方法；折腾了几个小时才勉强带错运行。只能看gentoo在哪一次更新中能顺便解决这个问题了。
