I do not understand what the following line does in .vimrc

nmap <silent> <leader>v :EditConfig<cr>

It seems that

  • nmap mean noremap
  • silent seems to mean apparently no beep in Vim
  • leader seems to mean the first character in the mode :
  • v seems to mean visual mode
  • EditConfig should be a command in vim in the mode : (However, it is not.)

What does the line mean in .vimrc?

  • nmap means "map a key sequence when in normal mode" (see vim's docs).
  • <silent> tells vim to show no message when this key sequence is used.
  • <leader> means the key sequence starts with the character assigned to variable mapleader -- a backslash, if no let mapleader = statement has executed yet at the point nmap executes.

And the v is the rest of the key sequence.

So overall this is mapping, in normal mode, a backslash-v key sequence to show no message and execute :EditConfig which is likely a function defined previously in the vimrc to edit configuration files (see for example this vimrc, search in browser for editconfig). :call EditConfig() at the end (as the vimrc file I gave the URL to uses) would be better, I believe.

Why :call EditConfig() would be better than :EditConfig? :curious-n00b-face:

It would appear that you are missing a function...

Try,

function! EditConfig() for config in ['$MYGVIMRC', '$MYVIMRC'] if exists(config) execute 'edit '.config endif endfor endfunction

Check this example.
