Termux配置Vim C++开发环境,打造基于终端命令行的IDE
主要利用Vim+Coc插件,配置C++的代码提示等功能。
Termux换源
打开termux,输入
termux-change-repo
找到mirrors.tuna.tsinghua.edu.cn,清华源,空格选中,回车确认
Termux配置ssh
有了ssh后,就可以方便的在PC或者其它平台上,使用ssh工具远程termux终端了
# 安装aptinstall open-ssh
# 启动sshd,默认端口为8022
sshd
# 关闭sshdpkill sshd
# 查看sshd是否运行ps aux |grep sshd
默认没有密码,使用
passwd
命令配置密码
ssh [email protected] -p8022
user用户名可以用
whoami
命令查看,一般termux用户名为u0_xxxx
软件包管理简介
termux使用pkg管理软件包,并且可以使用
apt
别名
例如更新仓库和软件:
pkg update
apt update
pkg upgrade
apt upgrade
两个命令都可以,
apt
命令对使用过Debian的人非常友好。以下全部使用
apt
安装命令就是
aptinstall xxx
安装基础软件
- vim:编辑器
- clang:C++编译器,并且提供了g++别名
- cmake:管理C++项目配置
- git:源码仓库工具
- nodejs:C++开发很少用到nodejs,主要是为vim插件提供运行环境
- python3:提供环境
aptinstallvim clang cmake git nodejs python3
Vim基础配置
主要配置缩进、tab空格、文件编码、行号等,可以根据自己的需求配置
配置项非常少,很基础
vim .vimrc
编辑
.vimrc
文件,将以下内容输入
" vim base config
set nocompatible
syntax on
set showmode
set showcmd
set encoding=utf-8
set t_Co=256
filetype indent on
set softtabstop=4
set tabstop=4
set shiftwidth=4
set expandtab
set autoindent
set number
set cursorline
安装Vim插件
- VimPlug:用来管理Vim插件,之后的插件都需要用它来安装
- vim-code-dark:VsCode主题
VimPlug插件管理
VimPlug主页提供了安装方法
复制下面的命令到终端并执行
curl-fLo ~/.vim/autoload/plug.vim --create-dirs \
https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
安装完成后编辑
.vimrc
文件,添加如下代码段
" plugin
call plug#begin()
Plug 'xxx'
call plug#end()
中间的
Plug 'xxx'
,就是代表安装xxx插件,每个插件一行
每当想安装新的插件时,先编辑vimrc,再重新进入vim命令模式,输入
:PlugInstall
就会安装插件
卸载插件时,编辑vimrc,删除插件那一行,然后进入vim命令模式,输入
:PlugClean
,不在列表里的插件就会被清理
:PlugUpdate
更新插件
:PlugUpgrade
更新VimPlug本身
VsCode颜色主题
Vim自己的高亮不好看,我选择了VsCode主题
Plug 'tomasiser/vim-code-dark'
添加上述代码,重新打开vim并运行
PlugInstall
,出现Finishing … Done!且插件名称后面显示100%时,说明安装成功
再次编辑vimrc,添加如下代码
colorscheme codedark
再次打开vim时,已经变为VsCode主题
Coc代码提示
参考Coc主页,安装方式如下:
Plug 'neoclide/coc.nvim', {'branch': 'release'}
同样,运行
:PlugInstall
就可以安装,Coc依赖于NodeJs
Coc是类似VimPlug的管理工具,具体的语言支持还需要安装语言包
其插件列表可以在CocWiki看到
注意,这里的插件指的是Coc插件,他们往往都按照coc-xxx命名,例如coc-clangd、coc-json等
安装插件需要使用
:CocInstall
命令,例如:
CocInstall coc-json coc-tsserver
Coc也需要配置,配置很多,我也没看明白,官网给了一个示例,主要是配置快捷键补全等功能。
对于C++开发环境,需要的Coc插件有
- coc-clangd:提供C++语言服务支持
- coc-cmake:提供cmake支持
coc-clangd
安装coc-clangd,依赖于clangd,在termux中使用
apt install clang
来安装
:ConInstall coc-clangd
安装完成后,可以编辑一个cpp文件尝试效果,Tab用来选择候选项,Enter用来确认
对于多文件项目或者CMake项目,插件需要读取
compile_commands.json
文件,这个文件需要在编译时生成。
CMake在构建项目时生成该文件,指令为:
cmake -S.-B build -DCMAKE_BUILD_TYPE=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS=TRUE
-S
指定源代码文件夹-B
指定输出目录-DCMAKE_BUILD_TYPE
设置构建类型-DCMAKE_EXPORT_COMPILE_COMMANDS
指定生成compile_commands.json
文件
coc-cmake
依赖cmake lsp
pip install cmake-language-server
:CocInstall coc-cmake
然后就可以使用了
括号补全
使用auto-pairs插件
Plug 'jiangmiao/auto-pairs'
无需任何配置
代码格式化
使用vim-clang-format插件,参考其主页安装
依赖于clang-format,在Termux下,安装clang就行
Plug 'rhysd/vim-clang-format'
安装完成后,可以参考如下代码或者ClangFormat主页配置格式化风格:
let g:clang_format#code_style='WebKit'
格式化命令为
:ClangFormat
为了方便,把
Ctrl+Shift+i
映射为该命令,在常规模式下有效:
nnoremap <C-S-i> :ClangFormat<CR>
缩进参考线
indentLine插件
Plug 'Yggdroot/indentLine'
无需配置
