Vim 配置 Golang 开发

2017-11-03

把 vim 打造成一个 Golang 开发的 IDE

0x001

首先,我们来看下最终的 VIM 是长下面这个样子的:

中间的那个框就是我们可以选择的函数列表,通过tab可以往下翻。接下来我们需要的是:

  • vim 这个当然是必须的啦。版本最好是最新的版本,最好是支持 lua
  • vim-go 用vim写 golang 必备的插件
  • pathogen.vim 这个用来处理runtimepath
  • ctrlp.vim 这个是文件搜索工具可以从 buf, mru, files 三个地方作为文件源
  • mru 最近经常编辑的文件列表
  • neocomplete 刚刚我们看到的那个选函数的框就是它
  • netrw.vim 左边的文件选择窗口
  • tagbar 右边的函数==的窗口

pathogen.vim

安装:

直接下载到~/.vim/autoload/pathogen.vim。或者

1
2
mkdir -p ~/.vim/autoload ~/.vim/bundle && \
curl -LSso ~/.vim/autoload/pathogen.vim https://tpo.pe/pathogen.vim

然后在你的vimrc里面添加:

1
execute pathogen#infect()

这个插件的作用是把~/.vim/bundle下面的所有文件夹作为 vim 的runtimepath(不知道的童鞋自行 Google)

vim-go

安装:

1
git clone https://github.com/fatih/vim-go.git ~/.vim/bundle/vim-go

对,你没有看错这样就已经安装完vim-go了。 只是它还会去安装一些第三方的东西比如:godef 等等

2019-04-12 UPDATE

源码编译 VIM8 (with-python3)

  1. 下载最新的源码,git clone git@github.com:vim/vim.git
  2. cd vim/src
  3. ./configure --enable-multibyte --enable-perlinterp=dynamic --enable-rubyinterp=dynamic --with-ruby-command=/usr/local/bin/ruby --enable-python3interp --enable-cscope --enable-gui=auto --with-features=huge --with-x --enable-fontset --enable-largefile --disable-netbeans --with-compiledby="yourname" --enable-fail-if-missing
  4. make && make install

需要的插件

出现以下 ERROR 解决办法

ERROR: [vim-hug-neovim-rpc] Vim(pythonx):Traceback (most recent call last):
ERROR: [vim-hug-neovim-rpc] Vim(pythonx):/must>not&exist/foo:1: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module’s documentation for alternative uses

命令行执行 pip3 install --user --no-binary :all: pynvim
