How can I insert empty ERB tags and put cursor inside it? It is similar to surrounding with surround plugin, but there is nothing to surround.

bla|bla
我想要这个:
bla<%= | %>bla
推荐答案
我将使用蒂姆·波普(Tim Pope)的Surround插件来完成此任务.
I would use Tim Pope's surround plugin to accomplish this.
在您的〜/.vim/after/ftplugin/erb.vim中添加以下内容
Add the following to you ~/.vim/after/ftplugin/erb.vim
let b:surround_{char2nr('=')} = "<%= \r %>"
let b:surround_{char2nr('-')} = "<% \r %>"
现在，当您按下<c-s>=时，它将按您的意愿插入<%= | %>.
Now when you press <c-s>= it will insert <%= | %> just as you wanted.
您可能还想看看蒂姆·波普(Tim Pope)的 ragtag插件，该插件已包含此类映射
You may also want to look at Tim Pope's ragtag plugin which has such mappings already included.
