老旧 Linux 体系搭建现代 C++ 开辟情况 —— 基于 neovim
问题背景公司配发的电脑是 macOS，一样平常开辟需要访问 Linux 虚拟机，出于安全方面的考虑，只能通过跳板机登录。这阻止了大多数长途图形界面的使用，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 搭建一套个人开辟情况，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。
体系情况
开始之前，先罗列下老旧体系的配置：
[*]硬件
[*]CPU： 2.40GHz * 2 核
[*]内存： 16G
[*]存储： 40G + 100G
[*]软件
[*]体系：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，都是公司本钱控制的泪~
软件安装
整个搭建过程是比较崎岖的，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。如果你的体系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，一样平常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样平常版本较低，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缘故原由，在开始安装各种软件之前，需要起首升级他们。
基础软件升级
gcc
体系提供的 4.8.5 编译根本是够用的，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爱，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，起首是确认当前体系 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)目前看是没有，需要使用 gcc 析出一份默认的：
> sudo bash -c 'gcc -dumpspecs > /usr/lib/gcc/x86_64-redhat-linux/4.8.5/specs'注意析出的路径就是上面加载路径中的第一条，内容如下：

如果不举行这个设置，后面在编译 lsp-server 中的 lsp-kind.nvim & nvim-lspconfig 模块时会失败：

glibc
体系提供的 2.17 不行，clangd 需要至少 2.18，否则 neovim 中跳转相干的键 (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 version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)具体升级过程可参考附录 2。
make
体系提供的 3.82 GNU Make 根本够用。
openssl
体系提供的 1.0.2k 根本够用。
git
体系提供的 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：
https://img2024.cnblogs.com/blog/1707550/202405/1707550-20240517153507678-1410975709.png
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：

别的最好更新 /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这里的 ip 都是通过反查相干域名得到的，可能会有所不同，详情参考附录 3。
wget
体系提供的 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

python3
体系提供的 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：

Please send bug reports and questions to <bug-wget@gnu.org>.不过可以通过直接下载 clang-format 来忽略这步，所以这里的 python3 没有升级，具体操作步调在安装 clang-format 时介绍。
cargo
rust 的包管理器，体系未提供，需要单独安装：
> sudo yum install libffi-devel
> wget https://www.python.org/ftp/python/3.8.1/Python-3.8.1.tgz
> tar -xvf Python-3.8.1.tgz
> cd Python-3.8.1

> sudo make altinstall
> sudo ln -sf /usr/local/python3/bin/python3.8 /usr/bin/python3
> sudo ln -sf /usr/local/python3/bin/pip3.8 /usr/bin/pip3用于后续安装 fd，它是一款 find 的替代者，可以实现更高效的文件查找，目前 yum 上最新的版本是 1.72.1。
go
go 语言编译器，体系未提供，需要单独安装：
> sudo yum install cargo
> cargo --version
cargo 1.65.0用来后续编译安装 efm-langserver，它是一款代码检察工具。目前 yum 源最新 go 版本是 1.20.12。为避免后续安装过程中出现网络访问错误的问题，可提前设置以下代理：
> sudo yum install go
> go version
go version go1.17.12 linux/amd64sqlite3
当地数据库，体系未提供，需要单独安装：
> go env -w GO111MODULE=on
> go env -w GOPROXY=https://goproxy.io,direct
> go env -w GOPRIVATE=*.corp.example.com用于后续安装 scheme ，它是一款语法高亮插件，使用 sqlite3 存储信息。

rg
全名 ripgrep，是 grep 替代者，功能更强大，不能直接使用 yum 安装，通过添加 yum 源的方式来曲线安装：
> sudo yum install sqlite sqlite-devel
> sqlite3 --version
3.7.17 2013-05-20 00:56:22 118a3b35693b134d56ebd780123b7fd6f1497668源是固定的，版本目前仍保持 13.0.0。
fd
全名 fd-find，用来替代 find，功能更强大，有之前安装 cargo 的基础，直接安装：
> sudo yum-config-manager --add-repo=https://copr.fedorainfracloud.org/coprs/carlwgeorge/ripgrep/repo/epel-7/carlwgeorge-ripgrep-epel-7.repo
> sudo yum install ripgrep
> rg --version
ripgrep 13.0.0
-SIMD -AVX (compiled)
+SIMD +AVX (runtime)基于最新的 cargo 1.72.1 安装会报错：
> cargo install fd-find
> sudo cp ~/.cargo/bin/fd /usr/local/bin/
> fd --version
fd 8.5.3看起来需要升级 rustc (1.74 > 1.72.1)，不过看到要安装的 fd-find 版本为 10.1.0，好像受到了启发，直接指定 fd-find 的版本为 8.5.3 重试：
> cargo install fd-find

tree-sitter
是一个解析器天生工具和增量解析库，在 nvim 中主要用作 latex 语言解析器、以及 rainbow-delimiters.nvim 和 nvim-treesitter.nvim 插件的底层支持。rainbow-delimiters 主要用于多种语言的语法高亮，特殊是多括号的展示；nvim-treesitter 主要用于高效代码导航与编辑，是 IDE 不可或缺的底层组件。
可以使用 cargo 安装：
> sudo cp /home/users/yunhai01/.cargo/bin/fd /usr/local/bin/
> fd --version
fd 8.5.3会遇到和安装 fd 类似的问题：

Try re-running cargo install with `--locked`最早之前安装的 0.20.7 版本是 ok 的，想通过这种方式安装的朋侪，可以指定版本试一下。注意这两种方式安装后的文件分别位于 ~/.cargo/bin 和 ./node_modules/tree-sitter-cli 下，需要手动复制到 /usr/local/bin 以便见效。
如今介绍第三种安装方式，不依赖 cargo、npm 等包管理器，直接定位到 tree-sitter 官方下载页面，选择 0.20.4 版本，对于我的 CentOS7 x64 版本，选择 tree-sitter-linux-x64.gz 下载即可：

efm-langserver 0.0.53 (rev: HEAD/go1.20.12)Font
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：
https://img2024.cnblogs.com/blog/1707550/202405/1707550-20240517204403986-1009438212.png
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：
https://img2024.cnblogs.com/blog/1707550/202405/1707550-20240517204848714-1565156.png
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：
https://img2024.cnblogs.com/blog/1707550/202405/1707550-20240517204730837-103619080.png

状态栏很多不能表现的符号都正常了 (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，缘故原由是 yum 上目前只有 0.3 版本的 neovim，而支持现代化 IDE 焦点的 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)启动：
> curl -LO https://github.com/neovim/neovim/releases/latest/download/nvim.appimage报错：
> chmod u+x nvim.appimage
> ./nvim.appimage看起来需要升级 glibc 2.29，为了避免再次更新 glibc，这里直接选择可以乐成安装的 neovim 0.9.2 版本：
/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)

下载乐成后，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如果运行后没有产生 squashfs-root 目录，阐明体系缺乏 FUSE (用户空间文件体系)，需要手动释放一下：
> chmod u+x nvim.appimage
> ./nvim.appimage设置到 /usr/local/bin 后就可以被全局引用了：
> ./nvim.appimage --appimage-extractnvimdots
IDE 的实现，按照 github 主页 README 的阐明直接安装：
> sudo ln -s $PWD/squashfs-root/AppRun /usr/local/bin/nvim
> nvim --version

fi执行过程中会让用户举行若干选项，都按默认处置处罚就可以了。到这里所有必须软件就都安装完成了，按任意键将进入插件的安装，具体内容在下一节介绍。
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：

开辟情况搭建
框架比如是毛坯房，想要入住还得“精装修”一下，主要是安装各种插件，以及当地化配置。
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，厥后更新到了 lazy，可以有效的提拔 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：
https://img2024.cnblogs.com/blog/1707550/202405/1707550-20240524190909496-1717910690.png
这个界面静静等待即可，最终都能安装乐成：
https://img2024.cnblogs.com/blog/1707550/202405/1707550-20240524200503044-1588807988.png
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。
https://img2024.cnblogs.com/blog/1707550/202405/1707550-20240524200554985-598972708.png
也可以直接在命令行输入 :Lazy sync 来切换到 Sync 标签：
https://img2024.cnblogs.com/blog/1707550/202405/1707550-20240524200626519-1686654906.png
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：
https://img2024.cnblogs.com/blog/1707550/202405/1707550-20240524160028965-100606491.png
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：
https://img2024.cnblogs.com/blog/1707550/202405/1707550-20240524201001924-1623736169.png
根本功能已经可用，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：
https://img2024.cnblogs.com/blog/1707550/202406/1707550-20240607113459209-343166960.png
可以观察到体系可用的语言插件、安装乐成的、安装失败的，这里主要需要处置处罚 2 个插件的安装。
clangd
从上面的日记可以看出，安装失败的缘故原由主要是从网络获取 clangd 包失败，这里改为手动下载：

https://img2024.cnblogs.com/blog/1707550/202406/1707550-20240607113158379-611750242.png
安装乐成，如果 nvim 仍表现安装 clangd，就多重启几次，甚至重启下机器。
clang-format
查看 clang-format 错误日记：
https://img2024.cnblogs.com/blog/1707550/202406/1707550-20240607111717037-989434053.png
没看出来安装失败的直接缘故原由，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

> 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替换到目标目录、设置命令软链接后，重启 nvim 查看：
https://img2024.cnblogs.com/blog/1707550/202406/1707550-20240607114254616-1771036578.png
安装乐成。如果想让 Mason 安装 clang-format，除了之前介绍的升级 python3 步调外，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末了还有两个插件 python-lsp-server & gopls 没安装乐成，分别是 python 与 go 语言 lspserver，由于本文着重介绍 C/C++ 情况的搭建，这个偏离主题就不再赘述了，有需求的小同伴可以在 nvimdots 中提问寻求帮助。
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，具体操作步调详见配置一节。
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这样就可以使用 vi 或 vim 代替 nvim 了，相当于替换了默认的 vim 编辑器，如果想调用原始的 vim 编辑器，需要输入完整路径：
alias vi=nvim
alias vim=nvim在举行配置之前，起首对 nvim 举行一次自我体验，这主要是通过 :checkhealth 命令来完成，下面是完整的 checkhealth 输出：
查看代码> /usr/bin/vi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：
https://img2024.cnblogs.com/blog/1707550/202406/1707550-20240607163617090-2037941782.png

:1: in main chunk本来是想改 colorscheme 选项的，厥后发现有个 background = dark，实验将这个改为 light 试试，重启后默认主题自动切换为 catppuccin-latte 了，下面是主题实时切换的结果：

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，很多多少 scheme 套件的状态栏展示有问题，黑乎乎的一块表现不清楚，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"
...主要修改 require("lualine").setup 一行中 theme = 的值即可，可供选择的值参考这篇。从代码上看，对于 catppuccin-* 主题，会做状态栏的同步，所以相对要好一些，可以无脑选择。
目前 nvimdots 对老旧体系的支持已经不错了，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举行设置了。
快捷键
nvimdots 提供了很丰富的快捷键支持，一样平常都是三键组合，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 都有阐明。自定义的键映射位于：~/.config/nvim/lua/core/mapping.lua
