问题背景
公司配发的电脑是 macOS，日常开发需要访问 Linux 虚拟机，出于安全方面的考虑，只能通过跳板机登录。这阻止了大多数远程图形界面的使用，让写代码的工作变得复杂起来，市面上非常好用的 VSCode 都用不了。因此考虑基于 vim 搭建一套个人开发环境，需要支持以下特性：
- 语法高亮 (风格可切换)
- 自动格式化
- 函数或变量定义跳转
- 函数或变量引用跳转
- 成员函数或变量下拉列表提示
- 函数或变量 TAB 键自动补齐
- 快速查找
- ……
考察了多种方案后，决定基于目前比较流行的 neovim 来打造，不过它面向的是比较新的 Linux 发行版，不知道我这个老的 CentOS7 能不能带起来，本文就是一个探索过程。
系统环境
开始之前，先罗列下老旧系统的配置：
- 硬件
- CPU： 2.40GHz * 2 核
- 内存： 16G
- 存储： 40G + 100G
- 软件
- 系统：CentOS Linux release 7.9.2009 (Core)
- kernel：3.10.0-1160.21.1.el7.x86_64
- rpm：4.11.3
- gcc：4.8.5 (备选 8.2)
- glibc：2.17
- make：GNU make 3.82
- openssl：1.0.2k
- git：1.8
- wget：1.14
- python: 3.6.8
确实是老旧，都是公司成本控制的泪~
软件安装
整个搭建过程是比较坎坷的，常常是装了 Z 之后才发现它依赖 X、Y，去安装 X、Y 的时候又发现一坨问题……这里为了直接上手，改为正叙模式，按这个方式一步步安装、升级，应该是没问题的。如果你的系统上已经存在依赖的软件且版本一致或更新，可以忽略对应安装过程。
在 Linux 上安装软件，一般有源码安装和包管理器安装两种方式，后者在 CentOS 上就是 yum 了，然而软件源提供的软件一般版本较低，有时需要使用前者，这就比较依赖 wget、git、gcc 和 make 了，这也是在上一节中列出他们版本的原因，在开始安装各种软件之前，需要首先升级他们。
基础软件升级
gcc
系统提供的 4.8.5 编译基本是够用的，后面代码格式化需要用到的 clang-format 模块如果是源码方式安装，要求 gcc 至少是 5.1，如果你有 5.1 及以上的 gcc 那更好。没有也没关系，本文会用其它方式绕过，毕竟升级 gcc 是一项大工程，没有半天是搞不定的，太耽误功夫。
虽然不必升级 gcc，但是一些代码库使用的高版本 gcc 默认了 -std=c99 选项，这点对老版本非常不友好，为此需要特意告诉老 gcc 编译器这个选项。具体就是修改 gcc 的 spec 文件，首先是确认当前系统 gcc 加载的 spec 文件：- > strace -e file gcc 2>&1 | grep specs
- access("/usr/lib/gcc/x86_64-redhat-linux/4.8.5/specs", R_OK) = -1 ENOENT (No such file or directory)
- access("/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../x86_64-redhat-linux/lib/x86_64-redhat-linux/4.8.5/specs", R_OK) = -1 ENOENT (No such file or directory)
- access("/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../x86_64-redhat-linux/lib/specs", R_OK) = -1 ENOENT (No such file or directory)
- access("/usr/lib/gcc/x86_64-redhat-linux/specs", R_OK) = -1 ENOENT (No such file or directory)
- > sudo bash -c 'gcc -dumpspecs > /usr/lib/gcc/x86_64-redhat-linux/4.8.5/specs'
查看代码再次运行 gcc，确认已加载修改后的 spec 文件：- > cat /usr/lib/gcc/x86_64-redhat-linux/4.8.5/specs.c99 | grep c99
- %{pg:%{fomit-frame-pointer:%e-pg and -fomit-frame-pointer are incompatible}} %{!iplugindir*:%{fplugin*:%:find-plugindir()}} %1 %{!Q:-quiet} %{!dumpbase:-dumpbase %B} %{d*} %{m*} %{aux-info*} %{fcompare-debug-second:%:compare-debug-auxbase-opt(%b)} %{!fcompare-debug-second:%{c|S:%{o*:-auxbase-strip %*}%{!o*:-auxbase %b}}}%{!c:%{!S:-auxbase %b}} %{g*} %{O*} %{W*&pedantic*} %{w} -std=c99 %{std*&ansi&trigraphs} %{v:-version} %{pg:-p} %{p} %{f*} %{undef} %{Qn:-fno-ident} %{Qy:} %{-help:--help} %{-target-help:--target-help} %{-version:--version} %{-help=*:--help=%*} %{!fsyntax-only:%{S:%W{o*}%{!o*:-o %b.s}}} %{fsyntax-only:-o %j} %{-param*} %{fmudflap|fmudflapth:-fno-builtin -fno-merge-constants} %{coverage:-fprofile-arcs -ftest-coverage}
如果不进行这个设置，后面在编译 lsp-server 中的 lsp-kind.nvim & nvim-lspconfig 模块时会失败：
glibc
系统提供的 2.17 不行，clangd 需要至少 2.18，否则 neovim 中跳转相关的键 (gd/gD) 会失效，而 yum 上没有大于 2.17 版本的软件可用，需要手动更新下：- > gcc -v
- Reading specs from /usr/lib/gcc/x86_64-redhat-linux/4.8.5/specs
- COLLECT_GCC=gcc
- COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-redhat-linux/4.8.5/lto-wrapper

- Thread model: posix
- gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)
make
系统提供的 3.82 GNU Make 基本够用。
openssl
系统提供的 1.0.2k 基本够用。
git
系统提供的 1.8 版本不行，需要升级到 2.38，否则不能识别 rebase=false 参数，导致插件更新时拉取代码库失败：
当时直接使用 yum install git 升级的版本还是比较低，所以我是手动安装的，但也取了个巧，直接安装了个 rpm 来更新 CentOS7 的软件源：- # 通过网盘链接下载 rpm 包
- # 链接: https://pan.baidu.com/s/1QAyqa04iZ45q1-HqeYH80Q?pwd=1234 提取码: 1234
- > ls -lh *.rpm

另外最好更新 /etc/hosts 文件以便加快对 github.com 的访问速度：- > sudo yum install https://packages.endpointdev.com/rhel/7/os/x86_64/endpoint-repo.x86_64.rpm
- > sudo yum install git
- > git --version
- git version 2.38.1
wget
系统提供的 1.14 版本不行，在拉取部分 lsp-server 时会出错 (cpp/lua)，需要升级到 1.21.3：- > cat /etc/hosts
- 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
- ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
- 140.82.114.3 github.com

- 140.82.114.6 api.github.com
- 140.82.114.10 codeload.github.com
python3
系统提供的 3.6.8 版本勉强够用，clang-format 编译安装要求 python 至少为 3.8 版本，可以选择安装 Python 3.8.1：- > curl -o wget-latest.tar.gz http://mirrors.ustc.edu.cn/gnu/wget/wget-latest.tar.gz
- > tar xvf wget-latest.tar.gz
- > cd wget-1.21.3

efm-langserver
实现智能 IDE 的核心，基于 go 语言开发，使用 go 编译安装：- > gunzip tree-sitter-linux-x64.gz
- > chmod u+x tree-sitter-linux-x64
- > sudo mv tree-sitter-linux-x64 /usr/local/bin
- > tree-sitter --version
- tree-sitter 0.20.4 (714bfd47a744ab44b904375c177a24c0614ef49c)
- > export GOPATH=/ext/tools> gunzip tree-sitter-linux-x64.gz

下载可支持符号的字体，例如：Nerd Font，在 macOS 上的安装非常简单，直接双击 ttf 文件安装：
然后在 macOS 终端上指定该字体，这里我使用的是 iTerm2，其它终端大同小异：
iTerm2 有以下 UI 路径：iTerm2 -> settings -> Profiles -> Default -> Text -> Font。下面是安装带符号字体前后的对比：
状态栏很多不能显示的符号都正常了 (标签页的仍保持问号，可能是一个特殊符号 Nerd Font 不支持)。
neovim
IDE 的载体，不使用 yum 安装，原因是 yum 上目前只有 0.3 版本的 neovim，而支持现代化 IDE 核心的 packer 包管理器至少需要 0.7 版本。这里使用 curl 直接下载最新版本：- > efm-langserver -v
- efm-langserver 0.0.44 (rev: 36a4d81/go1.17.12)
- > curl -LO https://github.com/neovim/neovim/releases/latest/download/nvim.appimage
- > chmod u+x nvim.appimage
- > ./nvim.appimage
- /tmp/.mount_nvim.aw3KspQ/usr/bin/nvim: /lib64/libc.so.6: version `GLIBC_2.28' not found (required by /tmp/.mount_nvim.aw3KspQ/usr/bin/nvim)
- /tmp/.mount_nvim.aw3KspQ/usr/bin/nvim: /lib64/libm.so.6: version `GLIBC_2.29' not found (required by /tmp/.mount_nvim.aw3KspQ/usr/bin/nvim)
下载成功后，运行 nvim.appimage 可以自动释放目标文件：- > curl -LO https://github.com/neovim/neovim/releases/latest/download/nvim.appimage
- > chmod u+x nvim.appimage
- > ./nvim.appimage
- > ./nvim.appimage --appimage-extract
IDE 的实现，按照 github 主页 README 的说明直接安装：- > sudo ln -s $PWD/squashfs-root/AppRun /usr/local/bin/nvim
- > nvim --version
- NVIM v0.9.2
- Build type: Release
- LuaJIT 2.1.1692716794
- system vimrc file: "$VIM/sysinit.vim"
- fall-back for $VIM: "/__w/neovim/neovim/build/nvim.AppDir/usr/share/nvim"
- Run :checkhealth for more info
- if command -v curl >/dev/null 2>&1; then
- bash -c "$(curl -fsSL https://raw.githubusercontent.com/ayamir/nvimdots/HEAD/scripts/install.sh)"
- else
- bash -c "$(wget -O- https://raw.githubusercontent.com/ayamir/nvimdots/HEAD/scripts/install.sh)"
- fi
安装后的目录位于：~/.config/nvim/。注意这里不要选择 neovim 0.8.1 (说的就是我)，否则后面启动插件管理器时会报错：- > bash -c "$(wget -O- https://raw.githubusercontent.com/ayamir/nvimdots/HEAD/scripts/install.sh)"

开发环境搭建
框架好比是毛坯房，想要入住还得“精装修”一下，主要是安装各种插件，以及本地化配置。
插件安装
同许多 IDE 一样，vim 很多功能是通过插件实现的，插件本身需要管理，这就催生了形形色色的插件管理器，知名的有 vim-plug、Vundle；vim 进化到 neovim 之后，有两个主要的插件管理器，一个是 packer，另一个是 lazy，两个都很好用，之前 nvimdots 使用的 packer，后来更新到了 lazy，可以有效的提升 neovim 的启动速度。
lazy
书接上节，在 nvimdots 安装结束后，按任意键将启动 nvim、自动拉起插件更新：
这个界面静静等待即可，最终都能安装成功：
在 lazy 插件管理页面，输入标签后面的字符可实现跳转，例如 U 跳转到更新插件页面。
也可以直接在命令行输入 :Lazy sync 来切换到 Sync 标签：
其它也类似，不再赘述。当所有插件安装结束后，q 退出界面。与原先的 packer 界面相比：
简直像从远古社会跨进到了现代社会。退出 lazy、退出 nvim，插件安装路径位于：~/.local/share/nvim 目录下。再次进入 nvim，将看到欢迎界面：
基本功能已经可用，有几个未安装的插件将继续安装。
mason
mason 也是一个插件管理器，聚焦于 lsp 服务、dap 服务、linter 和 formatter 方向，通过它可以让 nvim 轻松支持多种编程语言的智能化展示。通过 :Mason 启动：
可以观察到系统可用的语言插件、安装成功的、安装失败的，这里主要需要处理 2 个插件的安装。
clangd
从上面的日志可以看出，安装失败的原因主要是从网络获取 clangd 包失败，这里改为手动下载：- Error executing Lua callback: ...l/share/nvim/site/lazy/lazy.nvim/lua/lazy/view/float.lua:159: Vim(append):Error executing lua callback: ...zy/rainbow-delimiters.nvim/plugin/rainbow-delimiter

安装成功，如果 nvim 仍显示安装 clangd，就多重启几次，甚至重启下机器。
clang-format
查看 clang-format 错误日志：
没看出来安装失败的直接原因，这里改为手动下载：- > wget https://github.com/clangd/clangd/releases/download/18.1.3/clangd-linux-18.1.3.zip
- > mv clangd-linux-18.1.3.zip ~/.local/share/nvim/mason/packages
- > cd ~/.local/share/nvim/mason/packages
- > unzip clangd-linux-18.1.3.zip
- > cd ../bin
- > ln -s $PWD/../packages/clangd_18.1.3/bin/clangd clangd
- > ./clangd --version
- clangd version 18.1.3 (https://github.com/llvm/llvm-project c13b7485b87909fcf739f62cfa382b55407433c0)
- Features: linux+grpc
- Platform: x86_64-unknown-linux-gnu
安装成功。如果想让 Mason 安装 clang-format，除了之前介绍的升级 python3 步骤外，还需要以下操作：- > wget -c https://github.com/muttleyxd/clang-tools-static-binaries/releases/download/master-1d7ec53d/clang-format-10_linux-amd64
- > chmod u+x clang-format-10_linux-arm64
- > mkdir -p ~/.local/share/nvim/mason/packages/clang-format/bin
- > mv clang-format-10_linux-amd64 ~/.local/share/nvim/mason/packages/clang-format/bin
- > cd ~/.local/share/nvim/mason/bin
- > ln -s $PWD/../packages/clang-format/bin/clang-format-10_linux-amd64 clang-format
- > ./clang-format --version
- clang-format version 10.0.1
如果不想看到每次在启动时它们的报错信息，可以选择不加载它们，具体操作步骤详见配置一节。
配置
各种功能插件安装完成后，还需要修改化配置一番，为了方便调用 neovim，在 bash 启动脚本中增加以下内容：- > sudo pip3 install wheel
- # 进入 nvim
- MasonInstall clang-format
- alias vi=nvim
- alias vim=nvim
查看代码如果有插件工作不正常、老报警告框，可以通过自检发现一些问题。
主题
启动后默认的黑色背景看着黑乎乎的不够亮快，通过快捷键 (SPACE + f + c) 调出主题切换页：
这里选择 catppuccin-latte：
好多了。不过重启后就又恢复默认了，需要修改以下 lua 配置 (~/.config/nvim/lua/core/settings.lua)：-

2 核 CPU 切换有点费劲，毕竟是老旧机器，将就看吧~
状态栏
上一节中切换主题时，好多 scheme 套件的状态栏展示有问题，黑乎乎的一块显示不清楚，这是由于状态栏使用的插件 lualine 有自己的主题，需要单独设置，由于 lualine 属于插件，它们的配置文件位置稍有不同 (~/.config/nvim/lua/modules/configs/ui/lualine.lua)：- ...
- -- Set the colorscheme to use here.
- -- Available values are: `catppuccin`, `catppuccin-latte`, `catppucin-mocha`, `catppuccin-frappe`, `catppuccin-macchiato`.
- ---@type string
- settings["colorscheme"] = "catppuccin"
- -- Set it to true if your terminal has transparent background.
- ---@type boolean
- settings["transparent_background"] = false
- -- Set background color to use here.
- -- Useful if you would like to use a colorscheme that has a light and dark variant like `edge`.
- -- Valid values are: `dark`, `light`.
- ---@type "dark"|"light"
- settings["background"] = "dark"
- ...
目前 nvimdots 对老旧系统的支持已经不错了，早先我设置 blue 主题时，状态栏是这个样子：
根本没法看，通过设置 lualine 主题为 onenight 解决了这个问题：
目前已经不需要单独进行设置了。
快捷键
nvimdots 提供了很丰富的快捷键支持，一般都是三键组合，例如 +f+w 进入关键字搜索，其中 是可定义的，目前默认为空格键。
通过 :verbose nmap 可以查看所有的键映射：
想看单独的键可以在后面增加参数，例如输入 :verbose nmap gD ：
常用的 gD、gd、gh、gf、gr、K 都有说明。自定义的键映射位于：~/.config/nvim/lua/core/mapping.lua
