If a user is currently in a [vaulted](github.com/miquella/vaulted) shell, they will now have an indication of this in the agnoster prompt, not unlike the virtualenv prompt. The foreground color will switch if the timer expires (which usually signifies that the temporary Amazon keys generated by vaulted will be invalid).

# agnoster's Theme - https://gist.github.com/3712874
|
|
# A Powerline-inspired theme for ZSH
|
|
#
|
|
# # README
|
|
#
|
|
# In order for this theme to render correctly, you will need a
|
|
# [Powerline-patched font](https://github.com/Lokaltog/powerline-fonts).
|
|
# Make sure you have a recent version: the code points that Powerline
|
|
# uses changed in 2012, and older versions will display incorrectly,
|
|
# in confusing ways.
|
|
#
|
|
# In addition, I recommend the
|
|
# [Solarized theme](https://github.com/altercation/solarized/) and, if you're
|
|
# using it on Mac OS X, [iTerm 2](http://www.iterm2.com/) over Terminal.app -
|
|
# it has significantly better color fidelity.
|
|
#
|
|
# # Goals
|
|
#
|
|
# The aim of this theme is to only show you *relevant* information. Like most
|
|
# prompts, it will only show git information when in a git working directory.
|
|
# However, it goes a step further: everything from the current user and
|
|
# hostname to whether the last call exited with an error to whether background
|
|
# jobs are running in this shell will all be displayed automatically when
|
|
# appropriate.

|
|
# If this is not working for you, you probably have an old version of the
|
|
# Powerline-patched fonts installed. Download and install the new version.
|
|
# Do not submit PRs to change this unless you have reviewed the Powerline code point
|
|
# history and have new information.
|
|
# This is defined using a Unicode escape sequence so it is unambiguously readable, regardless of
|

# what font the user is viewing this source code in. Do not replace the

# Do not change this! Do not make it '\u2b80'; that is the old, wrong code point.
