Vim - Get a list of all mappings set in a specific file

Question

I was looking at my vimrc recently, and I was wondering which mappings I really use. So, I thought that a "mapcop" type plugin would be very useful, but that would require getting a list of all mappings defined in a certain file. I know that you can get where a mapping was defined by doing :verbose {map_type}map {mapping} , but that won't really cut it for what I want to use it for.

Answer 1

these commands could show {map_type}map {mapping} created in certain file:

:redir @x
:verbose map
:redir END
:%d|pu x
:g/filename$/-1 y M
:%d|pu m

• the filename you have to do escaping, like \\~\\/[.]vimrc$ for ~/.vimrc
• after executing this sequence, the mappings created in filename will be put in current buffer (the original text in buffer will be cleared)
• you can wrap those commands in function to make it easy to be called.
• note that the mappings in certain file are just last time defined in that file, same as your verbose map output

Answer 2

使用标签栏插件，您可以查看vimscript文件中定义的所有映射，包括.vimrc 。
