老旧 Linux 系统搭建现代 C++ 开发环境 —— 基于 neovim
goodcitizen 2024-07-31 11:45:00 阅读 98
一台 CentOS7 老机器,能不能打造基于 vim 的现代化 IDE?本文以实操为主,带你一步步搭建自己的环境
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 <code>-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)
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:

信息比较多,定位到关键字 *cc1_options:
, 在 %{w}

第一行的输出符合预期,整个过程可参考附录 4。
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:

具体升级过程可参考附录 2。
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:
<code>> 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
从而找到更新版本的 git,省了不少事。后来这个源还更新了,现在安装的话是 2.43 版本。
另外最好更新 /etc/hosts 文件以便加快对 github.com 的访问速度:
> 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
140.82.114.10 nodeload.github.com
140.82.114.6 api.github.com
140.82.114.10 codeload.github.com
这里的 ip 都是通过反查相关域名得到的,可能会有所不同,详情参考附录 3。
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:
> curl -o wget-latest.tar.gz http://mirrors.ustc.edu.cn/gnu/wget/wget-latest.tar.gz

目前的 wget-lastest 指向的最新版本是 1.24.5。
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:
> 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
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,具体操作步骤在安装 clang-format 时介绍。
cargo
rust 的包管理器,系统未提供,需要单独安装:
> sudo yum install cargo
> cargo --version
cargo 1.65.0
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,系统未提供,需要单独安装:
> sudo yum install go
> go version
go version go1.17.12 linux/amd64
用来后续编译安装 efm-langserver,它是一款代码审查工具。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:
> go env -w GO111MODULE=on
> go env -w GOPROXY=https://goproxy.io,direct
> go env -w GOPRIVATE=*.corp.example.com
sqlite3
本地数据库,系统未提供,需要单独安装:
> sudo yum install sqlite sqlite-devel
> sqlite3 --version
3.7.17 2013-05-20 00:56:22 118a3b35693b134d56ebd780123b7fd6f1497668
用于后续安装 scheme ,它是一款语法高亮插件,使用 sqlite3 存储信息。
升级后
- gcc:4.8.5
- glibc:2.18
- make:GNU make 3.82
- openssl:1.0.2k
- git:2.43
- wget:1.24.5
- python: 3.6.8
- cargo:1.72.1
- go:1.20.12
- sqlite3:3.7.17
依赖软件安装
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-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)
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:
> cargo install fd-find
> sudo cp ~/.cargo/bin/fd /usr/local/bin/
> fd --version
fd 8.5.3
基于最新的 cargo 1.72.1 安装会报错:
> cargo install fd-find

仍然不行,看来回退 8.5.3 是唯一的解决办法。之前还探索过将 cargo 版本降为 1.65.0:
> sudo yum remove cargo
> sudo yum install cargo-1.65.0-1.el7.x86_64
Loaded plugins: fastestmirror, langpacks, versionlock
Loading mirror speeds from cached hostfile
Excluding 1 update due to versionlock (use "yum versionlock status" to show it)
No package cargo-1.65.0-1.el7.x86_64 available.
Error: Nothing to do
未能成功。在网上也没搜到 1.65.0 的 cargo rpm 包,只能作罢。不清楚为何 1.72.1 的 cargo 要求 1.74 的 rustc,严重怀疑这是一个 bug。
书归正题,在安装完 fd 8.5.3 后需要按提示将 fd 移到 /usr/loca/bin:
> sudo cp /home/users/yunhai01/.cargo/bin/fd /usr/local/bin/
> fd --version
fd 8.5.3
否则 neovim 找不到。
tree-sitter
是一个解析器生成工具和增量解析库,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,特别是多括号的展示;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:
> cargo install tree-sitter-cli
会遇到和安装 fd 类似的问题:

Try re-running cargo install with `--locked`
增加 --locked
选项应该可以解决问题,使用 cargo 1.72.1 目前安装的版本为 0.22.6,这个版本运行依赖较高的 glibc,所以放弃。
通过官方提示的 npm 方式安装的结果也差不多:

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友,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 以便生效。
现在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:
> 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)
按上一面一步步执行就安装好了,亲测高于 0.20.4 的版本就有 glibc 兼容问题 (>2.18)。
efm-langserver
实现智能 IDE 的核心,基于 go 语言开发,使用 go 编译安装:
> go install github.com/mattn/efm-langserver@latest
安装后没有找到 efm-langserver,经查,go 1.20 之后,需要通过 GOPATH 环境变量来指定安装目录:
> export GOPATH=/ext/tools
> go install github.com/mattn/efm-langserver@latest
go: downloading github.com/mattn/efm-langserver v0.0.53
go: downloading github.com/sourcegraph/jsonrpc2 v0.2.0
go: downloading gopkg.in/yaml.v3 v3.0.1
go: downloading github.com/mattn/go-unicodeclass v0.0.2
go: downloading github.com/reviewdog/errorformat v0.0.0-20240311054359-739e471a49b3
同样需要复制到 /usr/local/bin 目录以便全局生效:
> sudo cp bin/efm-langserver /usr/local/bin
> efm-langserver -v
efm-langserver 0.0.53 (rev: HEAD/go1.20.12)
比之前安装的版本略高一些:
> efm-langserver -v
efm-langserver 0.0.44 (rev: 36a4d81/go1.17.12)
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:
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:
<code>> curl -LO https://github.com/neovim/neovim/releases/latest/download/nvim.appimage
启动:
> chmod u+x nvim.appimage
> ./nvim.appimage
报错:
/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)
看起来需要升级 glibc 2.29,为了避免再次更新 glibc,这里直接选择可以成功安装的 neovim 0.9.2 版本:
> wget https://github.com/neovim/neovim/releases/download/v0.9.2/nvim.appimage
友情提示:可以在 web 端下载后传递给虚拟机,macOS 访问 github 要比虚拟机快许多。
下载成功后,运行 nvim.appimage 可以自动释放目标文件:
> chmod u+x nvim.appimage
> ./nvim.appimage
如果运行后没有产生 squashfs-root
目录,说明系统缺乏 FUSE (用户空间文件系统),需要手动释放一下:
> ./nvim.appimage --appimage-extract
设置到 /usr/local/bin 后就可以被全局引用了:
> sudo ln -s $PWD/squashfs-root/AppRun /usr/local/bin/nvim
> nvim --version

else
bash -c "$(wget -O- https://raw.githubusercontent.com/ayamir/nvimdots/HEAD/scripts/install.sh)"

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 <code>: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:<code>~/.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 <code>: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:
<code>> 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
解压并替换到目标目录、设置命令软链接后,重启 nvim 查看:
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:
<code>> 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
替换到目标目录、设置命令软链接后,重启 nvim 查看:
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:
<code>> sudo pip3 install wheel
# 进入 nvim
MasonInstall clang-format
最后还有两个插件 python-lsp-server & gopls 没安装成功,分别是 python 与 go 语言 lspserver,由于本文着重介绍 C/C++ 环境的搭建,这个偏离主题就不再赘述了,有需求的小伙伴可以在 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:
alias vi=nvim
alias vim=nvim
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:
> /usr/bin/vi
在进行配置之前,首先对 nvim 进行一次自我体验,这主要是通过 :checkhealth
命令来完成,下面是完整的 checkhealth 输出:

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):
<code>...
-- 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"
...
本来是想改 colorscheme 选项的,后来发现有个 background = dark,尝试将这个改为 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效果:
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,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):
<code>...
local function custom_theme()
vim.api.nvim_create_autocmd("ColorScheme", {
group = vim.api.nvim_create_augroup("LualineColorScheme", { clear = true }),
pattern = "*",
callback = function()
has_catppuccin = vim.g.colors_name:find("catppuccin") ~= nil
require("lualine").setup({ options = { theme = custom_theme() } })
end,
})
...
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 <leader>+f+w 进入关键字搜索,其中 <leader> 是可定义的,目前默认为空格键。
通过 <code>: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 <code>: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

["c|<C-a>"] = map_cmd("<Home>"):with_noremap():with_desc("edit: Home"),
["c|<C-e>"] = map_cmd("<End>"):with_noremap():with_desc("edit: End"),
["c|<C-d>"] = map_cmd("<Del>"):with_noremap():with_desc("edit: Delete"),
["c|<C-h>"] = map_cmd("<BS>"):with_noremap():with_desc("edit: Backspace"),
["c|<C-t>"] = map_cmd([[<C-R>=expand("%:p:h") . "/" <CR>]])
:with_noremap()
:with_desc("edit: Complete path of current file"),
-- Visual mode
["v|J"] = map_cmd(":m '>+1<CR>gv=gv"):with_desc("edit: Move this line down"),
["v|K"] = map_cmd(":m '<-2<CR>gv=gv"):with_desc("edit: Move this line up"),
["v|<"] = map_cmd("<gv"):with_desc("edit: Decrease indent"),
["v|>"] = map_cmd(">gv"):with_desc("edit: Increase indent"),
}
bind.nvim_load_mapping(core_map)
这里有两个键是我之前用习惯的:Ctrl+j 向上移屏一行、Ctrl+k 向下移屏一行。vim 将这两个键映射到了 Ctrl+e 和 Ctrl+y,一直觉得用着不太顺手,可以手动添加:
:nmap <C-j> <C-e>
:nmap <C-k> <C-y>
然而重启 nvim 后就不起作用了。可以在上面的配置文件中加入以下内容实现永久修改:
-- Move Up/Down
["n|<C-h>"] = map_cmd("<C-e>"),
["n|<C-l>"] = map_cmd("<C-y>"),
["n|<C-k>"] = map_cmd("<C-y>"):with_noremap(),
["n|<C-j>"] = map_cmd("<C-e>"):with_noremap(),
注意由于 Ctrl+h/j/k/l 已被 nvimdots 挪为它用,为防止热键冲突,需要将之前的注释掉:
-- ["n|<C-h>"] = map_cmd("<C-w>h"):with_noremap():with_desc("window: Focus left"),
-- ["n|<C-l>"] = map_cmd("<C-w>l"):with_noremap():with_desc("window: Focus right"),
-- ["n|<C-j>"] = map_cmd("<C-w>j"):with_noremap():with_desc("window: Focus down"),
-- ["n|<C-k>"] = map_cmd("<C-w>k"):with_noremap():with_desc("window: Focus up"),
看起来是用于窗口切换 (Ctrl+w+h/j/k/l) 了,感觉没啥必要。注意看 Ctrl+j 与 Ctrl+h、Ctrl+k 与 Ctrl+l 只相差了一个 :with_noremap()
,这个能起什么作用?看下面这个演示就清楚了:
加了了 :with_noremap() 的,会上下滑动多行,实现按更少的键的目的。
PS:目前在新版本的 nvimdots 上,新增的键还是不起作用,目前还没有精力研究,回头研究通了再更新一波~
编程语言支持
相比于主流的 IDE 只能支持若干编程语言,neovim+nvimdots 搭建的 IDE 更加强大,可以轻松支持几十种语言,是冷门语言开发者的福音。输入 <code>:LspInfo 查看已安装的语言服务:
这是 nvimdots 的默认配置,可以通过修改配置文件来增加或删除语言服务 (~/.config/nvim/lua/core/settings.lua):
<code>...
-- Set the language servers that will be installed during bootstrap here.
-- check the below link for all the supported LSPs:
-- https://github.com/neovim/nvim-lspconfig/tree/master/lua/lspconfig/server_configurations
---@type string[]
settings["lsp_deps"] = {
"bashls",
"clangd",
"html",
"jsonls",
"lua_ls",
"pylsp",
"gopls",
}
-- Set the general-purpose servers that will be installed during bootstrap here.
-- Check the below link for all supported sources.
-- in `code_actions`, `completion`, `diagnostics`, `formatting`, `hover` folders:
-- https://github.com/nvimtools/none-ls.nvim/tree/main/lua/null-ls/builtins
---@type string[]
settings["null_ls_deps"] = {
"clang_format",
"gofumpt",
"goimports",
"prettier",
"shfmt",
"stylua",
"vint",
}
-- Set the Debug Adapter Protocol (DAP) clients that will be installed and configured during bootstrap here.
-- Check the below link for all supported DAPs:
-- https://github.com/jay-babu/mason-nvim-dap.nvim/blob/main/lua/mason-nvim-dap/mappings/source.lua
---@type string[]
settings["dap_deps"] = {
"codelldb", -- C-Family
"delve", -- Go
"python", -- Python (debugpy)
}
...
主要就是修改 lsp_deps 数组了。例如对于不需要且没有安装成功的 pylsp 和 gopls,直接删除之。重启 nvim 后,不再报烦人的警告了。

保存时美化
各种 formatter 设置好了不用岂不可惜,所以 nvimdots 默认的行为是关闭文件自动使用对应语言的 formatter 进行格式美化。然而在浏览第三方库文件或其它开源库代码时,这么做就有点画蛇添足了,通过 FormatToggle
可以关闭默认选项,然而重启 nvim 后又会自动打开,因此需要修改配置文件 (~/.config/nvim/lua/core/settings.lua):
...
-- Set it to false if there are no need to format on save.
---@type boolean
settings["format_on_save"] = true
-- Set it to false if the notification after formatting is annoying.
---@type boolean
settings["format_notify"] = true
-- Set it to true if you prefer formatting ONLY the *changed lines* as defined by your version control system.
-- NOTE: This entry will only be respected if:
-- > The buffer to be formatted is under version control (Git or Mercurial);
-- > Any of the server attached to that buffer supports |DocumentRangeFormattingProvider| server capability.
-- Otherwise Neovim would fall back to format the whole buffer, and a warning will be issued.
---@type boolean
settings["format_modifications_only"] = false
-- Set the format disabled directories here, files under these dirs won't be formatted on save.
--- NOTE: Directories may contain regular expressions (grammar: vim). |regexp|
--- NOTE: Directories are automatically normalized. |vim.fs.normalize()|
---@type string[]
settings["format_disabled_dirs"] = {
-- Example
"~/format_disabled_dir",
}
...
将 format_on_save
改为 false 即可。
效果
至此基于 neovim 的 IDE 就搭建完成了,在正式开始演试之前,需要为 efm-langserver 插件生成一份代码编译清单:compile_commands.json。
compile_commands
这个文件的内容是实际传递给编译器的命令行,包括各种参数:
...
{
"directory": "/ext/code/transmission/build/libtransmission",
"command": "/opt/compiler/gcc-8.2/bin/g++ -DCURL_STATICLIB -DFMT_EXCEPTIONS=0 -DFMT_HEADER_ONLY=1 -DHAVE_FALLOCATE64 -DHAVE_FLOCK -DHAVE_GETMNTENT -DHAVE_GETTEXT -DHAVE_LIBINTL_H -DHAVE_MKDTEMP -DHAVE_NGETTEXT -DHAVE_POSIX_FADVISE -DHAVE_POSIX_FALLOCATE -DHAVE_PREAD -DHAVE_PWRITE -DHAVE_SENDFILE64 -DHAVE_SO_REUSEPORT=1 -DHAVE_STATVFS -DHAVE_SYS_STATVFS_H -DHAVE_XLOCALE_H -DMINIUPNP_STATICLIB -DNATPMP_STATICLIB -DPACKAGE_DATA_DIR=\\\"/usr/local/share\\\" -DPOSIX -DSYSTEM_MINIUPNP -DWIDE_INTEGER_DISABLE_FLOAT_INTEROP -DWIDE_INTEGER_DISABLE_IOSTREAM -DWITH_INOTIFY -DWITH_UTP -D__TRANSMISSION__ -I/ext/code/transmission/build/libtransmission -I/ext/code/transmission/third-party/libutp/include -I/ext/code/transmission/third-party/libb64/include -I/ext/code/transmission/third-party/jsonsl -I/ext/code/transmission/third-party/wildmat -isystem /ext/code/transmission/build/third-party/libdeflate.bld/pfx/include -isystem /usr/local/include -isystem /ext/code/transmission/cmake/../third-party/fast_float/include -isystem /ext/code/transmission/build/third-party/libpsl.bld/pfx/include -isystem /ext/code/transmission/build/third-party/libnatpmp.bld/pfx/include -isystem /ext/code/transmission/build/third-party/miniupnpc.bld/pfx/include -isystem /ext/code/transmission/build/third-party/dht.bld/pfx/include -isystem /ext/code/transmission/cmake/../third-party/utfcpp/source -isystem /ext/code/transmission/cmake/../third-party/wide-integer -isystem /ext/code/transmission/cmake/../third-party/fmt/include -isystem /ext/code/transmission/build/third-party/libevent.bld/pfx/include -O3 -DNDEBUG -fPIC -W -Wall -Wextra -Wcast-align -Wduplicated-cond -Wextra-semi -Wfloat-equal -Winit-self -Wint-in-bool-context -Wlogical-op -Wmissing-format-attribute -Wnull-dereference -Wpointer-arith -Wredundant-decls -Wrestrict -Wshadow -Wsign-compare -Wsuggest-override -Wuninitialized -Wunreachable-code -Wunused -Wunused-const-variable -Wunused-parameter -Wunused-result -Wwrite-strings -std=gnu++17 -o CMakeFiles/transmission.dir/session.cc.o -c /ext/code/transmission/libtransmission/session.cc",
"file": "/ext/code/transmission/libtransmission/session.cc"
},
...
如此,efm-langserver 等语言服务,就能借助这里的信息,更好的理解代码,例如哪些预处理中的代码是生效的,从而更好的实现符号跳转与补全等功能。这类清单也用于 ccls、VSCode 等 IDE 中,并不是 efm-langserver 专属的。一般项目本身并不包含这类清单,需要单独生成一下,下面分项目类型分别介绍。
- cmake:cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1 .
- make:bear make
- Android NDK
- ndk-build GEN_COMPILE_COMMANDS_DB=true
- bear ndk-build
- ninja:ninja -f out/combined-kona.ninja -t compdb | tee ./compile_commands.json
- ...
cmake、ninja 支持的比较好,NDK 算 make 的一种,也有自己的选项可以设置,对于最原始的 make,只能借助于 bear 命令了,另外 ndk-build 也可以基于这种方式生成。
bear
bear 是一个用来生成包含编译时选项的数据库的工具。 通常它将输出文件 compile_commands.json ,可以供给例如 vscode 中的 Microsoft C/C++ 插件或者 vim 中的 YouCompleteMe 插件使用,让插件可以正确的解析当前 C++ 源文件的各种依赖信息,例如头文件包含路径。
在 CentOS 上默认没有这个命令,需要安装一下,默认的 yum 源没有,需要源码安装:
wget https://github.com/rizsotto/Bear/archive/refs/tags/2.4.4.zip
unzip 2.4.4.zip
cd Bear-2.4.4
mkdir build; cd build
cmake ..
make
sudo make install
安装过程也比较简单,CentOS7 适合老一点的版本,2.4.4 实测可用。
transmission
下面用一个 BitTorrent 网络传输方面很知名的开源库 tranmission 从头到尾做个测试。
git clone --recurse-submodules git@github.com:firedgirl/transmission.git transmission
cd transmission
git checkout -b 4.0.x origin/4.0.x
mkdir build; cd build
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1 -DCMAKE_CXX_COMPILER=/opt/compiler/gcc-8.2/bin/g++ -DCMAKE_C_COMPILER=/opt/compiler/gcc-8.2/bin/gcc -DCMAKE_CXX_FLAGS="-Wl,-rpath,/opt/compiler/gcc-8.2/lib64 -I /usr/local/include" -DCMAKE_BUILD_TYPE=Release .. code>
make -j8
注意添加到 cmake 中的 -DCMAKE_EXPORT_COMPILE_COMMANDS=1
选项,他的作用和 bear 是一致的。项目编译完成后,将在根目录生成一个 compile_commands.json 文件,内容比较多就不展示了,感兴趣的可以看这个链接。
将它移动到项目根目录,打开 neovim,就可以像 VSCode 一样浏览啦。上面的 transmission 只是一个例子,可以更换为任意 c/c++ 开源库。有的平台不支持 compile_commands.json 的生成,此时符号跳转就没那么准了,不过文件内的一些函数定义跳转还是支持的。
功能展示
自动补全
这里演示的是成员变量与成员函数,其它像普通变量、函数调用什么的也都能自动补全。
字符串查找
Telescope 插件,底层基于 fzf & rg,快捷键 SPACE + f + w 调出。缺点有以下几点
- 多次查询一个关键字不便,需要每次输入关键词且从头开始遍历
- 跳转到某个文件再查找,会局限查找范围为文件当前所在目录
对于第二个问题,在老版本上通过修改配置可以修复,具体修改 ~/.config/nvim/lua/core/event.lua:
<code>{ "BufEnter", "*", "silent! lcd %:p:h" },
将上面这行注释掉即可。但是目前新版本,这个配置不见了,目前还没有抽出精力来研究。
符号跳转
上图演示了几种典型的跳转场景:
- gD:声明、调用点跳转定义
- K:提示定义
- gd:小窗显示定义
除了 c++ 中的虚函数都能比较好的进行处理,虚函数由于是运行时才能确定调用哪个实现,这里跳不过去也情有可原,但是如果能将备选的实现列出来让用户自己选择,就更好了。
上面的动图,展示的是 gh 命令查找所有调用点,在弹出的浮窗中,右侧按文件列出所有调用点,进入文件下面每个调用点时,左侧可以预览,回车时跳转到调用点。大部分时间可用,有时一些符号找不到,就得使用之前的字符串查找了。
h/cpp 文件切换
ClangdSwitchSourceHeaderVSplit,基于 clangd,快捷键 SPACE + h 调出,同级别的还可以使用 ClangdSwitchSourceHeader & ClangdSwitchSourceHeaderSplit,前者直接替换当前 buffer,后者是横向分屏,可以让 SPACE + h 指向其中任何一个,看个人偏好。头文件可以不必和 cpp 在同一个目录,这个插件一样可以找到。
后记
第一次入坑 neovm + nvimdots 是 2022.11 的事情了,最近有新机器了又在 2024.07 搞了一次,发现nvimdots 有很大更新,以至于之前的一些快捷键、UI 发生了变化,一些移植经验也已经不适用了,虽然一度很懵逼,但这是一件好事,说明 neovim + 基于 lua 的插件配置正在蓬勃发展,现在写出来的文字,可能过一两年又面目全非了。总归来说,现在这条路是对的,比那些还在坚守 vim + gtags + cscope + YouCompleteMe… 老路的要强大太多了,现在网上这方面的资料,远远跟不上开源社区的进步速度,毫不夸张的说,关于 vim 搭建现代化 IDE 的文章,只要超过五年以上,就是老古董了,除非研究技术发展历史,否则没必要深究。
基于 lua 的 neovim 配置还有很多,nvimdots 只是其中的一个,其实他们采用的基础插件是相通的,像 Lazy、Mason、Lsp 等等,这种项目像一个粘合剂,将各种零散的小插件整合在一起,达到用户开箱即用的效果,免去了很多插件搜索的过程,各位有使用的好的项目,也可以在留言区分享哈~
关于 nvimdots 的任何使用问题都可以在 Issue 页面提问,之前我在这里提的一些问题,很快就有人回复,一些不错的建议还得到了采纳,成就感满满!总之,除了一帮子中国人在那飙英文有点受不了,其它都还好😅。
