We already restore IFS to its default value. This patch only changes the
way it is done to avoid a call to 'echo' in a sub-shell at runtime.
Fixes#267.
The behavior of porcelain seems more adapted to the liquidprompt usage
From the "git status" documentation :
The porcelain format is similar to the short format, but is guaranteed
not to change in a backwards-incompatible way between git versions or
based on user configuration. This makes it ideal for parsing by scripts.
The description of the short format above also describes the porcelain
format, with a few exceptions:
1. The user’s color.status configuration is not respected;
color will always be off.
[...]
In some cases (multi user enabled in screen for example), the count of
detached screen sessions was incorrect. The command to locate these has
been improved using a more tolerant regex, which does not require
'detached' to be the first word inside the parenthesis.
To test, open a new screen session, add multiuser (type Ctrl+A, then
':', then multiuser on), then detach (Ctrl+A, Ctrl+D), and see that
liquidprompt detects the screen, as would "screen -list".
Merge changes from the develop branch:
- many fixes, in particular for MacOS X (battery)
- many speed improvments (Mercurial, Subversion)
- many reliability improvments (SHORTEN_PATH feature)
Ready for a release.
When LP_PATH_KEEP=0 and current dirname were over maximum length the
name was also shorten. With this fixed _lp_shorten_path should now
always return at least the complete current dirname.
The previous implementation had shell specific paths which did not
produce the same result. It did not respect the maximum length which it
calculated. And for specific cases even repeated part of the path.
This implementation is portable across bash and zsh.
It respects maximum length strictly and only exceeds it when it has to
respect LP_PATH_KEEP leading dirs.
It adds support for only showing the current directory, without leading
ones. This fixes Issue #219.
