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

apt install open-ssh

# 启动sshd,默认端口为8022

sshd

# 关闭sshd

pkill 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 user@192.168.0.11 -p 8022

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

apt install 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

apt install vim 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 :ClangFormat

缩进参考线

indentLine插件

Plug 'Yggdroot/indentLine'

无需配置
