1 # Some bash code to get information about the current SCM repository.
3 # Usage: add ". .bash-scm" into your .bashrc
5 # Description of the functions:
9 # This can be used to display the current branch or revision inside the
10 # bash prompt by adding $(current_scm_info) into the PS1 string.
14 # Information to display as the tab title. To avoid having a too long
15 # string this output the name of the repository (if any) and the current
16 # working directory. If outside a repository then the last two
17 # directories are output. It is possible to pass one agurment true/false
18 # to tab_title which is to output the hostname as prefix followed by
19 # ':'. So the full format is:
21 # host:[repository] dir
