Background to the issue
The company's computers are macOS, and daily development requires access to a Linux virtual machine, which can only be accessed via a springboard for security reasons. This prevents the use of most remote graphical interfaces, complicating the work of writing code, and the very good VSCode on the market does not work. Therefore, we are considering building a personal development environment based on vim, which needs to support the following features:
- Syntax highlighting (style switchable)
- Auto formatting
- Function or Variable Definition Jumps
- Function or variable reference jumps
- Member function or variable drop-down list hints
- Function or variable TAB key auto-completion
- Quick Find
- ……
After examining a variety of options, I decided to build it based on the currently popular neovim, but it is geared towards newer Linux distributions, so I don't know if my old CentOS7 will be able to bring it up, and this article is an exploration of that process.
system environment
Before we start, let's list the configurations of older systems:
- software
- CPU: 2.40GHz * 2 cores
- Memory: 16G
- Storage: 40G + 100G
- hardware
- System: 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 (alternative 8.2)
- glibc：2.17
- make：GNU make 3.82
- openssl：1.0.2k
- git：1.8
- wget：1.14
- python: 3.6.8
Old indeed, it's all a tear in the company's cost control~
software installation
The whole building process is quite bumpy, often after installing Z only to realize that it depends on X, Y, and when you go to install X, Y, you find a pile of problems ...... Here in order to get started directly, changed to the main narrative mode, according to this way of installing and upgrading step by step, it should be no problem. If you already have dependent software on your system with the same version or newer, you can ignore the installation process.
To install software on Linux, there are generally two ways to do it: source installation and package manager installation, the latter of which is yum on CentOS. However, the software provided by the source is generally of a lower version, and sometimes you need to use the former, which relies more on wget, git, gcc, and make, which is why their versions were listed in the previous section, and you need to upgrade them first before you start to install the various software. This is why they were listed in the previous section, and you need to upgrade them first before you start installing the various software.
Basic software upgrades
gcc
The 4.8.5 compilation provided by the system is basically enough, but the clang-format module that is needed to format the code behind is required to be at least 5.1 if it is installed from source, so if you have 5.1 and above, then it's better. If you don't have gcc 5.1 and above, it's better. It doesn't matter if you don't have gcc 5.1 or above, this article will use other ways to bypass it.
Although you don't have to upgrade gcc, some libraries use a higher version of gcc that defaults to the-std=c99 option, which is very unfriendly to older versions, so you need to tell the old gcc compiler about this option. To do this, you need to tell the old gcc compiler about this option. The first thing you need to do is change the gcc spec file, by checking which spec file is loaded by gcc on the current system:
> 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)It doesn't look like it at the moment, you need to analyze a copy of the default using gcc:
> sudo bash -c 'gcc -dumpspecs > /usr/lib/gcc/x86_64-redhat-linux/4.8.5/specs'Notice that the parsed path is the first of the loaded paths above, which reads as follows:

gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)The output of the first line is as expected and the whole process can be found in Appendix 4.
Without this setting, compiling the & nvim-lspconfig module in lsp-server will fail later:
glibc
The 2.17 provided by the system doesn't work, clangd needs to be at least 2.18, or else the jump-related keys (gd/gD) in neovim won't work, and there's nothing older than 2.17 available on yum, so you need to manually update it:
# Download via web link rpm contract (to or for)

make
The 3.82 GNU Make provided with the system is basically sufficient.
openssl
The 1.0.2k provided by the system is basically sufficient.
git
The 1.8 version provided by the system doesn't work, you need to upgrade to 2.38, otherwise it can't recognize the rebase=false parameter, which leads to failure in pulling the codebase when the plugin is updated:
At the time, yum install git upgraded me to a lower version, so I installed it manually, but I also took the liberty of installing an rpm to update the CentOS7 repositories:
> sudo yum install /rhel/7/os/x86_64/endpoint-repo.x86_64.rpm
> sudo yum install git
> git --version
git version 2.38.1This saved me a lot of work, as I was able to find a newer version of git. The source has since been updated and is now version 2.43 when installed.
It is also a good idea to update the /etc/hosts file for faster access:
> cat /etc/hosts
127.0.0.1 localhost localhost4 localhost4.localdomain4
::1 localhost localhost6 localhost6.localdomain6
140.82.114.3
140.82.114.10
140.82.114.6
140.82.114.10 The ip's here are all obtained by back-checking the relevant domains and may vary, refer to Appendix 3 for details.
wget
The 1.14 version provided by the system doesn't work, it gives an error when pulling part of the lsp-server (cpp/lua), and needs to be upgraded to 1.21.3:
> curl -o /gnu/wget/
> tar xvf
> cd wget-1.21.3
> ./configure --with-ssl=openssl
> make -j8
> sudo make install
> wget --version

python3
The 3.6.8 version provided by the system is barely sufficient, but the clang-format compilation installation requires python to be at least 3.8, so you can install Python 3.8.1 as an option:
> sudo yum install libffi-devel
> wget /ftp/python/3.8.1/Python-3.8.
> tar -xvf Python-3.8.
> cd Python-3.8.1
> ./configure --prefix=/usr/local/python3
> make -j8
> 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/pip3However, this step can be ignored by downloading clang-format directly, so python3 is not upgraded here, as described in Installing clang-format.
cargo
The package manager for rust is not provided and needs to be installed separately:
> sudo yum install cargo
> cargo --version
cargo 1.65.0For subsequent installations of fd, an alternative to find for more efficient file finding, the latest version on yum is 1.72.1.
go
The go language compiler, which is not provided by the system, needs to be installed separately:
> sudo yum install go
> go version
go version go1.17.12 linux/amd64It is used to compile and install efm-langserver, which is a code review tool. The latest go version of the yum source is 1.20.12. In order to avoid network access errors during subsequent installations, you can set up the following proxy in advance:
> go env -w GO111MODULE=on
> go env -w GOPROXY=,direct
> go env -w GOPRIVATE=*.sqlite3
Local database, not provided by the system, needs to be installed separately:
> sudo yum install sqlite sqlite-devel
> sqlite3 --version

rg
The full name is ripgrep, it's a grep replacement, more powerful, can't be installed directly by yum, it's installed by adding yum sources to the curve:

Caused by:
package `clap_builder v4.5.2` cannot be built because it requires rustc 1.74 or newer, while the currently active rustc version is 1.72.1It still doesn't work, so it seems that rolling back to 8.5.3 is the only solution. Also explored previously was downgrading cargo to 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 doIt didn't work. I couldn't find a cargo rpm package for 1.65.0 on the web, so I had to stop. I'm not sure why 1.72.1 cargo requires 1.74 rustc, but I seriously doubt it's a bug.
To get back to the point, after installing fd 8.5.3 you need to move fd to /usr/loca/bin when prompted:
> sudo cp /home/users/yunhai01/.cargo/bin/fd /usr/local/bin/
> fd --version
fd 8.5.3Otherwise neovim won't find it.

Realization of the core of the intelligent IDE , based on the go language development , using go compile and install :
> go install /mattn/efm-langserver@latestI didn't find efm-langserver after installing it. After checking, after go 1.20, you need to specify the installation directory via GOPATH environment variable:
> export GOPATH=/ext/tools

Download fonts that can support symbols, for example:Nerd FontThe installation on macOS is very simple, just double-click on the ttf file to install it:
Then specify the font in your macOS terminal. I'm using iTerm2 here, but other terminals are similar:
iTerm2 has the following UI paths: iTerm2 -> settings -> Profiles -> Default -> Text -> Font. Below is a comparison between before and after installing a font with symbols:
Many of the symbols in the status bar that could not be displayed are now normal (the question mark on the tabs remains, probably a special symbol that Nerd Font does not support).
neovim
The reason for not using yum to install the IDE carrier is that there is only version 0.3 of neovim on yum, and the packer package manager that supports the modern IDE core requires version 0.7 at least. Use curl to download the latest version directly:
> curl -LO /neovim/neovim/releases/latest/download/Initiation:
> chmod u+x
> ./Report an error:
/tmp/.mount_nvim.aw3KspQ/usr/bin/nvim: /lib64/.6: version `GLIBC_2.28' not found (required by /tmp/.mount_nvim.aw3KspQ/usr/bin/nvim)
/tmp/.mount_nvim.aw3KspQ/usr/bin/nvim: /lib64/.6: version `GLIBC_2.29' not found (required by /tmp/.mount_nvim.aw3KspQ/usr/bin/nvim)It looks like you need to update glibc 2.29, so to avoid having to update glibc again, you can just choose the version of neovim 0.9.2 that you can install successfully:
> wget /neovim/neovim/releases/download/v0.9.2/Tip: You can download it on the web and pass it on to a virtual machine. macOS access to github is much faster than a virtual machine.
After successful download, run it to automatically release the target file:
> chmod u+x
> ./If the run does not producesquashfs-root directory, it means that the system lacks FUSE (File System in User Space) and you need to free it manually:
> ./ --appimage-extractSetting it to /usr/local/bin will allow it to be globally referenced:

Development Environment Setup
The framework is like a rough house, want to move in still have to "fine-tune" a bit, mainly to install a variety of plug-ins, as well as the localization of the configuration.
Plug-in Installation
Like many IDEs, many features of vim are realized by plugins, and the plugins themselves need to be managed, which gives rise to all kinds of plugin managers, the well-known ones are vim-plug and Vundle; after vim evolved to neovim, there are two main plugin managers, one is packer, the other is lazy, both are very good, and before that, nvimdots used packer. Before nvimdots used packer, but later updated to lazy, which can effectively improve the startup speed of neovim.
lazy
The book picks up where the previous section left off, at the end of the nvimdots installation, pressing any key will start nvim, automatically pulling up the plugin updates:
This interface just wait quietly, and eventually all can be installed successfully:
On the lazy plugin management page, enter the characters after the label to jump, e.g. U to the update plugin page.
It is also possible to type directly on the command line:Lazy sync to switch to the Sync tab:
Others are similar and will not be repeated. When all plugins are installed, q exits the interface. Compared to the original packer interface:
It's almost like crossing over from an ancient society to a modern one. Exit lazy, exit nvim, the plugin installation path is located:~/.local/share/nvim directory. Enter nvim again and you will see the welcome screen:
Basic functionality is available and a few uninstalled plugins will continue to be installed.
mason
mason is also a plugin manager focusing on lsp services, dap services, linter and formatter directions, which allows nvim to easily support intelligent presentations in multiple programming languages. It allows nvim to easily support intelligent presentations in multiple programming languages through the:Mason Initiation:
You can observe the language plug-ins available to the system, those that were installed successfully, and those that failed to be installed, and here you mainly need to deal with the installation of 2 plug-ins.
clangd
As you can see from the above logs, the main reason for the installation failure is the failure to get the clangd packages from the network, so we changed to download them manually:
> wget /clangd/clangd/releases/download/18.1.3/clangd-linux-18.1.
> mv clangd-linux-18.1. ~/.local/share/nvim/mason/packages
> cd ~/.local/share/nvim/mason/packages
> unzip clangd-linux-18.1.
> cd ../bin

clangd version 18.1.3 (/llvm/llvm-project c13b7485b87909fcf739f62cfa382b55407433c0)
Features: linux+grpc
Platform: x86_64-unknown-linux-gnuAfter unzipping and replacing it in the target directory and setting the command softlink, restart nvim to view it:
The installation was successful, if nvim still shows that clangd is installed, reboot a few more times, or even reboot the machine.
clang-format
View the clang-format error log:
Didn't see a direct reason for the failed installation, so here's a manual download instead:

clang-format version 10.0.1After replacing it in the target directory and setting the command softlink, restart nvim to view it:
The installation was successful. If you want Mason to install clang-format, you need to do the following in addition to the python3 upgrade steps described previously:
> sudo pip3 install wheel
# go into nvim
MasonInstall clang-formatFinally, there are two plug-ins python-lsp-server & gopls not installed successfully, respectively, python and go language lspserver, because this article focuses on the construction of the C/C++ environment, this deviation from the theme will not be repeated, there is a need for partners can be in thenvimdots Ask questions for help in the middle.
You can choose not to load them if you don't want to see them reporting errors every time you start them up, as detailed in the Configuration section.
configure
After the installation of various functional plug-ins, you still need to modify the configuration a bit, in order to facilitate the call neovim, in the bash startup script to add the following content:
alias vi=nvim
alias vim=nvimThis allows you to use vi or vim instead of nvim, which is equivalent to replacing the default vim editor. If you want to call the original vim editor, you need to enter the full path:
> /usr/bin/viBefore proceeding with the configuration, start by giving nvim a taste of itself, which is mostly done through the:checkhealth command to do so, here is the complete checkhealth output:

thematic
The default black background after startup is not bright enough, use the shortcut keys (SPACE + f + c) to bring up the theme switching page:
Select catppuccin-latte here:
Much better. However, after reboot it's back to default, you need to change the following lua configuration (~/.config/nvim/lua/core/):
...
-- 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"
...Originally I wanted to change the colorscheme option, but then I found that there is a background = dark, try to change this to light to try, after restarting the default theme automatically switched to catppuccin-latte, the following is the effect of real-time theme switching:
It's a bit hard to switch between 2 core CPUs, after all, it's an old machine, just take it for what it's worth~.
status line
When switching themes in the previous section, many scheme packages have problems displaying the status bar, the black piece is not clear, this is due to the status bar using the plugin lualine has its own theme, you need to set it up individually, since lualine is a plugin, their configuration files are in slightly different locations (~/.config/nvim/lua/modules/ configs/ui/):
...
local function custom_theme()
.nvim_create_autocmd("ColorScheme", {
group = .nvim_create_augroup("LualineColorScheme", { clear = true }),
pattern = "*",
callback = function()
has_catppuccin = .colors_name:find("catppuccin") ~= nil
require("lualine").setup({ options = { theme = custom_theme() } })
end,
})
...Main modificationsrequire("lualine").setup first linetheme = value is sufficient, the optional value referencethis one. From the code, for catppuccin-* theme, it will do the status bar synchronization, so it's relatively better and can be a no-brainer choice.
Currently nvimdots has good support for older systems, earlier when I set up the blue theme the status bar looked like this:
Couldn't see it at all, solved this by setting the lualine theme to onenight:
There is no longer a need for a separate setup.
(computer) shortcut key
nvimdots provides rich support for shortcuts, which are generally three-key combinations, e.g. <leader>+f+w to enter a keyword search, where <leader> is definable and currently defaults to the spacebar.
pass (a bill or inspection etc):verbose nmap All key mappings can be viewed:
To see the individual keys you can add parameters after them, for example by typing:verbose nmap gD ：
The commonly used gD, gd, gh, gf, gr, and K are described. Customized key mappings are located in: ~/.config/nvim/lua/core/

bind.nvim_load_mapping(core_map)There are two keys I'm used to: Ctrl+j to move up one line and Ctrl+k to move down one line. vim maps these keys to Ctrl+e and Ctrl+y, which I've never felt comfortable using, so you can add them manually:
:nmap <C-j> <C-e>
:nmap <C-k> <C-y>However, restarting nvim doesn't work. You can make this permanent by adding the following to the configuration file above:
-- 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(),Note that since Ctrl+h/j/k/l is already used by nvimdots, you need to comment out the previous ones to prevent hotkey conflicts:
-- ["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"),It looks like it's used for window switching (Ctrl+w+h/j/k/l), but it doesn't feel necessary. Note that Ctrl+j and Ctrl+h, and Ctrl+k and Ctrl+l only differ by one:with_noremap()What does this do? Watch this demo below to get a clear picture:
With :with_noremap(), you can slide multiple rows up and down to achieve the goal of pressing fewer keys.
PS: The new keys still don't work on the new version of nvimdots, I haven't had the energy to look into it yet, so I'll update it when I get through it~.
Programming Language Support
Compared to mainstream IDEs that can only support a few programming languages, the IDE built by neovim+nvimdots is much more powerful and can easily support dozens of languages, which is a boon for cold language developers. Input:LspInfo View installed language services:
This is the default configuration of nvimdots. Language services can be added or removed by modifying the configuration file (~/.config/nvim/lua/core/):
...
-- Set the language servers that will be installed during bootstrap here.
-- check the below link for all the supported LSPs:
-- /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:
-- /nvimtools//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:
-- /jay-babu//blob/main/lua/mason-nvim-dap/mappings/
---@type string[]
settings["dap_deps"] = {
"codelldb", -- C-Family
"delve", -- Go
"python", -- Python (debugpy)
}
...The main thing is to modify the lsp_deps array. For example, if you don't need pylsp and gopls and they didn't install, you can just delete them. After restarting nvim, no more annoying warnings.
There is also a list of languages supported by tree-sitter in checkhealth:

Beautify on save
It would be a shame not to use the various formatters once they are set up, so the default behavior of nvimdots is to disable the automatic formatting of files with the corresponding language formatter. However, when browsing third-party library files or other open-source library code, it's a bit of a red herring to do so, and you can do it with theFormatToggle You can turn off the default option, but it will be turned on again after restarting nvim, so you need to modify the configuration file (~/.config/nvim/lua/core/):
...
-- 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. |()|
---@type string[]
settings["format_disabled_dirs"] = {
-- Example
"~/format_disabled_dir",
}
...commander-in-chief (military)format_on_save Change it to false and you're good to go.
effect
At this point, the neovim-based IDE has been built, and before we can officially start the test, we need to generate a code compilation manifest for the efm-langserver plugin: compile_commands.json.
compile_commands
The contents of this file are the actual command lines passed to the compiler, including the various arguments:
...
{
"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//pfx/include -isystem /usr/local/include -isystem /ext/code/transmission/cmake/../third-party/fast_float/include -isystem /ext/code/transmission/build/third-party//pfx/include -isystem /ext/code/transmission/build/third-party//pfx/include -isystem /ext/code/transmission/build/third-party//pfx/include -isystem /ext/code/transmission/build/third-party//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//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// -c /ext/code/transmission/libtransmission/",

},
...In this way, language services such as efm-langserver can use the information here to better understand the code, e.g. which code in preprocessing is in effect, and thus better implement features such as symbol jumping and complementation. Such lists are also used in IDEs like ccls, VSCode, etc. and are not specific to efm-langserver. Generally, the project itself does not contain this kind of list, and you need to generate it separately, which is described below by project type.
- 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/ -t compdb | tee ./compile_commands.json
- ...
cmake, ninja support is better, NDK is a kind of make, also has its own options can be set, for the most primitive make, can only resort to bear command, in addition, ndk-build can also be generated based on this way.
bear
bear is a tool for generating databases containing compile-time options. Normally it takes the output filecompile_commands.json This can be supplied to, for example, the Microsoft C/C++ plug-in for vscode or the YouCompleteMe plug-in for vim, so that the plug-in can correctly parse various dependencies of the current C++ source file, such as header file include paths.
This command is not available by default on CentOS, so you need to install it. The default yum source is not available, so you need to install it from source:
wget /rizsotto/Bear/archive/refs/tags/2.4.
unzip 2.4.
cd Bear-2.4.4
mkdir build; cd build
cmake ..
make
sudo make installThe installation process is also relatively simple, CentOS7 is suitable for older versions, 2.4.4 is tested to work.
transmission
Here's a test from start to finish using tranmission, a well known open source library for BitTorrent network transfers.
git clone --recurse-submodules git@:firedgirl/ transmission
cd transmission
git checkout -b 4. origin/4.
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 ..
make -j8Note the addition of the-DCMAKE_EXPORT_COMPILE_COMMANDS=1 option, his role is the same as bear. After the project is compiled, a compile_commands.json file will be generated in the root directory, which has a lot of content, so I won't show it here.link (on a website)。
Move it to the root directory of your project, open neovim, and you can browse it like VSCode. The above transmission is just an example, it can be replaced by any c/c++ open source library. Some platforms don't support the generation of compile_commands.json, so the symbolic jumps are not so accurate, but some function definitions in the file are still supported.
Function
auto-complete
The demo here is for member variables and member functions, but other things like normal variables, function calls, and so on can also be auto-complete.
String lookup
Telescope plugin, underlying based on fzf & rg, shortcut key SPACE + f + w call. The disadvantages are as follows
- Multiple queries for a keyword are inconvenient, you need to enter the keyword each time and traverse from the beginning.
- Jumping to a file and searching for it limits the search to the current directory of the file.
For the second issue, it can be fixed on older versions by modifying the configuration by modifying ~/.config/nvim/lua/core/:
{ "BufEnter", "*", "silent! lcd %:p:h" },Just comment out the line above. But with the current new version, this configuration is missing, and I haven't taken the time to look into it yet.
Symbol Jump
The diagram above demonstrates several typical jump scenarios:
- gD: declaration, call point jump definition
- K: Cue Definition
- gd: small window display definition
Except for the virtual functions in c++, which can be handled relatively well, the virtual functions can only be determined at runtime which implementation to call, so it's understandable that they can't be skipped over here, but it would be nice if the alternative implementations could be listed so that the user can choose for themselves.
The above picture shows the gh command to find all the call points, in the popup window, the right side lists all the call points by file, when you enter each call point under the file, the left side can be previewed, and enter to jump to the call point. Most of the time, sometimes some symbols can not be found, you have to use the previous string search.
h/cpp file switching
ClangdSwitchSourceHeaderVSplit, based on clangd, shortcut SPACE + h to call it out, the same level can also use ClangdSwitchSourceHeader & ClangdSwitchSourceHeaderSplit, the former is directly replace current The former replaces the current buffer directly, the latter splits the screen horizontally, and you can have SPACE + h point to any of them, depending on your preference. The header files don't have to be in the same directory as the cpp, but can be found by the plugin.
postscript
The first time I got into neovm + nvimdots was in 2022.11, and I recently got a new machine and did it again in 2024.07, and I realized that nvimdots has been updated a lot, so much so that some of the shortcuts and UIs have changed, and some of the porting experience doesn't apply any more, which is a good thing, even though I was very confused for a while. lua-based plugin configuration is booming, and what I write now may not be the same in a year or two. After all, this is the right path, than those who still adhere to vim + gtags + cscope + YouCompleteMe... the old way to be too powerful, and now online information in this regard, far from keeping pace with the progress of the open source community, it is no exaggeration to say that, on the vim to build a modern IDE of the article, as long as more than five years It's no exaggeration to say that articles about vim building modern IDEs that are more than five years old are old, so unless you're studying the history of technology development, there's no need to dig deeper.
lua-based neovim configuration there are many, nvimdots is just one of them, in fact, they use the basic plug-ins are similar, like Lazy, Mason, Lsp, etc., this kind of project is like a glue, will be a variety of scattered small plug-ins integrated together, to achieve the effect of the user out-of-the-box that is, eliminating the need to search for a lot of plug-ins, you have to use a good project! You have a good use of the project, you can also share in the message area ha ~!
Any questions about the use of nvimdots can be answered in theIssue The page asks questions, and some of the questions I asked here were answered very quickly, and some good suggestions were adopted, so I feel a sense of fulfillment! All in all, except for a bunch of Chinese people who are a bit too much for me to handle in English, everything else is fine 😅.
