#coc 插件配置

# coc 插件配置 coc插件原理 vscode 补全利用的是LSP (language server protocol), 简单理解就是编辑时启动一个进程，补全果过程就类似app请求服务器得到补全数据。这就是为什么要装node，服务进程都是node启动。 # 第一步 安装nvim 首先你需要 安装vim8 或者nvim 我测试的是macos 如果是nvim， 需要把nvim 的配置文件做一次软链接指向 ~/.vimrc 这是延续以前的vim配置方式, 不做的话，只能修改init.vim , nvim的配置默认读取这个文件。 以下下提到的都是nvim，我在/etc/profile alias vim="nvim" 了 ln -s ~/.config/nvim/init.vim ~/.vimrc

12# 第二步 安装nvim插件管理器 Vim-plug curl -fLo ~/.config/nvim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

1打不开这个域名，可以直接去github搜索plug.vim ,手动复制下来. # 第四步 如何安装php补全插件 各种语言coc扩展这里有 (opens new window)

coc-phpactor 是php7以上才可以用

coc-phpls 一般都用这个

第一步 需要安装Intelephense

npm i intelephense -g

1 第二步打开vim, 安装coc-phpls

CocInstall coc-phpls

1 第三步 配置php language server (opens new window)

vim : CocConfig 会默认打开一个配置文件 ```

{

"languageserver": {

"intelephense": {

"command": "intelephense",

"args": ["--stdio"],

"filetypes": ["php"],

"initializationOptions": {

"storagePath": "/Users/kunming/php/"

}

}

}

```

这里外面的intelephense表示配置的名称 command里面的intelephense是一个文件 args 表示可执行文件后面的参数 比如你打开一个php文件，ps命令可以看到系统会启动一个进程 node /usr/local/bin/intelephense --stdio 有一个索引js的进程/usr/local/bin/node --no-warnings /Users/kunming/.SpaceVim/plugged/coc.nvim/build/index.js node还会启动一个进程类似这样/usr/local/Cellar/node/14.1.0/bin/node /Users/kunming/.config/coc/extensions/node_modules/coc-phpls/node_modules/intelephense/lib/intelephense.js --node-ipc --clientProcessId=72264 filetypes 指定了对php文件有效 storagePath 表示初始化信息存储的位置，据我观察应该是打开一个文件，进程为php建立补全信息建立的索引日志文件，安装intelephense，会附带好多php文件，常见的php库，也是为了建立索引用的，初次编辑一个php文件，这个目录会有28872930这样的文件夹。 mac上貌似只有你在storagePath目录下建立的php文件或者项目，vim编辑才会出现补全提示，在别的目录是没有提示的，这一点研究了好久才感觉出来，文档也没说这些 centos7下面貌似没这些问题， 都可以提示出来，可以不配置CocConfig。 # 其余插件，我只安装了go的coc扩展和coc的python扩展，go需要fatih/vim-go来支持 同样每次编辑他们的文件都会启动一个类似node进程/usr/local/bin/node --no-warnings /Users/kunming/.SpaceVim/plugged/coc.nvim/build/index.js 都是一个套路： 1.找到所需的插件，比如coc-python 安装他需要的依赖，一般插件后面会提到 vim中安装coc扩展 CocInstall coc-python vim来打配置CocConfig，添加对应语言的server配置 所以LSP是一个cs结构的，有服务端也就是node进程， 客户端就是vim编辑器 set nu
