Vim - how to store and execute commonly used commands?

Question

If I wanted to process a batch of text files with the same set of commands for example:

:set tw=50
gggqG

Can I save the above and run it with a shortcut command?

Answer 1

If you want to use it only once, use a macro as specified in some of the other answers. If you want to do it more often, you can include the following line in your .vimrc file:

:map \r :set tw=50<CR>gggqG

This will map \r to cause your two lines to be executed whenever you press \r. Of course you can also choose a different shortcut, like <C-R> (Ctrl+R) or <F12> or something.

Answer 2

The following in .vimrc will define a new command Wrap that does what you want.

command! Wrap :set tw=50 | :normal gggqG

Call it with :Wrap
