Mac Terminal and Vim syntax coloring on CentOS server

• You can switch from bash to zsh. I will not describe here how to set up mode indicator in Z-Shell – there are a lot of howtos over Internet, e. g.: [1], [2].
• If you’re using GNU Bash version 4.3 (most probably you are not, it was released last month, so you'd need to upgrade), you can set Readline option show-mode-in-prompt.

Like so:

set show-mode-in-prompt On

in your .inputrc or

bind 'set show-mode-in-prompt On'

as a shell command. This adds a character to the beginning of the prompt indicating the editing mode: @ for Emacs, : and + for vi normal and vi insertion respectively.

I. e. your prompt will look like +agzam@pc:~$ in input mode and :agzam@pc:~$ in normal mode. As far as I understand this can not been customized in any way, but still it’s better than nothing.

If you use MacVim, the easiest way is:

set macmeta

So that MacVim will treat alt/option as Meta key, you can then bind:

nmap <C-M-S> :call foo_func()

The keys pressed for above is: Ctrl+alt+s.

Hope this helps and solves your issue, happy Vimming!
