* agnoster: improve perf with use of $jobstates (zsh/parameter module) This saves multiple fork/execs (for the subshell and wc) each time the prompt is rendered * agnoster: compute git repo_path only when in a git repo this avoids needlessly invoking git twice every time we render the prompt * agnoster: avoid subshell when rendering prompt Rather than forking a subshell to print the prompt, construct it incrementally by appending to $PROMPT. v2: fix incorrect CURRENT_BG v3: fix bzr and hg prompting Thanks @mcornella for the help.

# 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.
|
|
|

# NOTE: This segment separator character is correct. In 2012, Powerline changed
|

# the code points they use for their special characters. This is the new code point.
|
|
# 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
|

# escape sequence with a single literal character.

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