display git branch in statusbar

[georges-hatem]

I'm trying to use '#(shell-command)' to display the status of my git branch, but output is blank.

to debug, i replaced it with '#(ls -l)', and refreshed the theme through VIM. it showed '0', which makes sense because we're inside VIM.

exit vim, the count is still 0 even though that's not true.

Looks like the commands are not updating, which is surprising since #W changes upon path, and time and date update as well.

Any ideas?

I'm not sure if it's exactly what you're looking for, but if you just want to display the branch name in the tmuxline status, this worked for me:

#(cd #{pane_current_path}; git rev-parse --abbrev-ref HEAD)

Here is my tmuxline_preset from my .vimrc:

let g:tmuxline_preset = {
    \'a'    : '#S',
    \'b'    : '#W',
    \'c'    : '#(cd #{pane_current_path}; git rev-parse --abbrev-ref HEAD)',
    \'cwin' : ['#I', '#W'],
    \'win'  : ['#I', '#W'],
    \'x'    : '#{?client_prefix,Prefix,      }',
    \'y'    : ['%a', '%e-%b-%Y', '%l:%M%p'],
    \'z'    : '#h'}
