# [Blogs](../blog/) >> Use Vim as a C/C++ IDE
|
||||
|
||||
This is a general guide for using SpaceVim as a C/C++ IDE, including layer configuration and usage.
|
||||
Each of the following sections will be covered:
|
||||
|
||||
<!-- vim-markdown-toc GFM -->
|
||||
|
||||
- [Enable language layer](#enable-language-layer)
|
||||
- [code completion](#code-completion)
|
||||
- [alternate file jumping](#alternate-file-jumping)
|
||||
- [code running](#code-running)
|
||||
- [code format](#code-format)
|
||||
- [REPL support](#repl-support)
|
||||
|
||||
<!-- vim-markdown-toc -->
|
||||
|
||||
### Enable language layer
|
||||
|
||||
To add C/C++ language support in SpaceVim, you need to enable the `lang#c` layer. Press `SPC f v d` to open
|
||||
SpaceVim configuration file, and add following configuration:
|
||||
|
||||
```toml
|
||||
[[layers]]
|
||||
name = "lang#c"
|
||||
```
|
||||
|
||||
for more info, you can read the [lang#c](../layers/lang/c/) layer documentation.
|
||||
|
||||
### code completion
|
||||
|
||||
By default the autocomplete layer has been enabled, so after loading `lang#c` layer, the code completion
|
||||
for C/C++ language should works well.
|
||||
|
||||
|
||||
### alternate file jumping
|
||||
|
||||
To manage the alternate file for a project, you may need to create a `.project_alt.json` file in the root of your
|
||||
project.
|
||||
|
||||
for exmaple, add following content into the `.project_alt.json` file:
|
||||
|
||||
```json
|
||||
{
|
||||
"*.c": {"alternate": "{}.h"},
|
||||
"*.h": {"alternate": "{}.c"}
|
||||
}
|
||||
```
|
||||
|
||||
with this configuration, you can jump between the alternate file via command `:A`
|
||||
|
||||
|
||||
### code running
|
||||
|
||||
The default code running key binding is `SPC l r`. It will compile and run current file asynchronously.
|
||||
And the stdout will be shown on a runner buffer.
|
||||
|
||||
|
||||
|
||||
|
||||
### code format
|
||||
|
||||
The format layer use neoformat as default tool to format code, it will format current file.
|
||||
And the default key binding is `SPC b f`.
|
||||
|
||||
```toml
|
||||
[[layers]]
|
||||
name = "format"
|
||||
```
|
||||
|
||||
### REPL support
|
||||
|
||||
Start a `igcc` inferior REPL process with `SPC l s i`. After the REPL process being started, you can
|
||||
send code to inferior process, all key bindings prefix with `SPC l s`, including sending line, sending selection or even
|
||||
send whole buffer.

# [Blogs](../blog/) >> 使用 Vim 搭建 C/C++ 开发环境
|
||||
|
||||
SpaceVim 是一个模块化的 Vim IDE，针对 C/C++ 语言的支持主要依靠 `lang#c` 模块以及与之相关的其它模块。
|
||||
的这篇文章主要介绍如何使用 SpaceVim 搭建 C/C++ 的开发环境，侧重介绍跟 C/C++ 开发相关使用技巧。
|
||||
在阅读这篇文章之前，可以先阅读《[使用 Vim 搭建基础的开发环境](../use-vim-as-ide/)》，对语言相关以外的功能有一个大致的了解。

|
||||
|
||||
### 安装模块
|
||||
|
||||
SpaceVim 初次安装时默认并未启用相关语言模块。首先需要启用
|
||||
`lang#c` 模块，通过快捷键 `SPC f v d` 打开配置文件，添加如下片断：
|
||||
|
||||
```toml
|
||||
[[layers]]
|
||||
name = "lang#c"
|
||||
```
|
||||
|
||||
启用 `lang#c` 模块后，在打开 C/C++ 文件时，就可以使用语言专属快捷键，这些快捷键都是以 `SPC l` 为前缀的。
|
||||
|
||||
### 代码自动补全
|
||||
|
||||
`autocomplete` 模块为 SpaceVim 提供了自动补全功能，目前针对 PHP 而言，比较好的补全方案是配合使用 lsp 模块：
|
||||
|
||||
```toml
|
||||
[[layers]]
|
||||
name = "lsp"
|
||||
```
|
||||
|
||||
lsp 模块默认使用 `clangd` 作为 C/C++ 的语言服务器后台命令。
|
||||
|
||||
在配置文件中添加如下内容即可为 C/C++ 启用语言服务器：
|
||||
|
||||
```toml
|
||||
[[layers]]
|
||||
name = "lsp"
|
||||
filetypes = [
|
||||
"c",
|
||||
"cpp"
|
||||
]
|
||||
[layers.override_cmd]
|
||||
c = ["clangd"]
|
||||
```
|
||||
|
||||
### 语法检查
|
||||
|
||||
`checkers` 模块为 SpaceVim 提供了语法检查的功能，该模块默认已经载入。该模块默认使用 [neomake](https://github.com/neomake/neomake)
|
||||
这一异步语法检查工具。对于 C/C++ 的支持，是通过异步调用 gcc 命令来完成的。
|
||||
|
||||
### 工程文件跳转
|
||||
|
||||
SpaceVim 自带工程管理插件，可以识别项目根目录，自动跳转 alternate 文件。需要在项目根目录添加工程文件 `.project_alt.json`：
|
||||
|
||||
```json
|
||||
{
|
||||
"*.c": {"alternate": "{}.h"},
|
||||
"*.h": {"alternate": "{}.c"}
|
||||
}
|
||||
```
|
||||
|
||||
通过以上的配置，就可以使用命令 `:A` 在源文件和测试文件之间进行跳转。
|
||||
|
||||
|
||||
### 代码格式化
|
||||
|
||||
C/C++ 代码格式化，主要依赖 `format` 模块，快捷键为 `SPC b f`，异步执行 `clang-format` 命令：
|
||||
|
||||
```toml
|
||||
[[layers]]
|
||||
name = "format"
|
||||
```
|
||||
|
||||
### 快速运行
|
||||
|
||||
在编辑 C/C++ 文件时，可以快速运行当前文件，默认的快捷键是 `SPC l r` 。按下后，
|
||||
会在屏幕下方打开一个插件窗口，运行的结果会被展示在窗口内。于此同时，光标并不会跳到该插件窗口，避免影响编辑。在这里需要说明下，
|
||||
|
||||
|
||||
|
||||
### 交互式编程
|
||||
|
||||
在编辑 C/C++ 文件时，可通过快捷键 `SPC l s i` 启动 `php -a` 交互窗口，
|
||||
之后使用快捷键将代码发送至解释器。默认快捷键都以 `SPC l s` 为前缀。
