Vim:双击后删除注释字符 [英] Vim: Remove comment character after double enter

问题描述

在 Vim 中，我喜欢允许您在启动注释块后自动插入注释的功能.您将如何使它在换行符后获得注释字符，但是在获得第二个换行符时，该注释被删除，并且您开始一个没有注释字符的换行符.如果您正在处理评论块并且之后不想再发表评论，这将很有帮助(在我的情况下，我也想将相同的内容应用于降价列表，将 */- 视为评论字符).

例如

//输入注释//(点击一次回车后光标在这里)

和

//输入注释(按两次输入后光标在此处)

解决方案

此映射检查当前行是否只包含注释前导，然后再决定它是 还是 :

inoremap <CR>getline(".") =~ '^\s*\(\*\|//\|#\|"\)\s*$' ? "\" : "\;"

In Vim, I like the feature that allows you to auto insert comments after you have started a comment block. How would you make it so that you get a comment character(s) after a newline, but upon getting a second newline that comment is removed and you start a newline without a comment character. This would be helpful if you are working on a comment block and don't want to make anymore comments after that (in my case I also want to apply the same thing to markdown lists, treating */- as comment characters).

For example

// typing a comment
// (cursor here after hitting enter once)

And

// typing a comment

(cursor here after hitting enter twice)

解决方案

This mapping checks if the current line contains only comment leaders before deciding if it does <C-u> or <CR>:

inoremap <expr> <CR> getline(".") =~ '^\s*\(\*\|//\|#\|"\)\s*$' ? "\<C-u>" : "\<CR>"
