#
# rtfpessoa's Theme - https://gist.github.com/rtfpessoa/9737c2d0d3b5fe5aa2e8
# Inspired by the original agnoster from https://github.com/agnoster/agnoster-zsh-theme
# A Powerline-inspired theme for ZSH
#
# # README
#
# In order for this theme to render correctly, you will need a
# [Powerline-patched font](https://gist.github.com/1595572).
# 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.
### Segment drawing
# A few utility functions to make it easy and re-usable to draw segmented prompts

# Special Powerline characters
# Defines vars with the special prompt and Powerline characters
# Use this in conjunction with "local SEGMENT_SEPARATOR BRANCH DETACHED PLUSMINUS CROSS LIGHTNING GEAR"
# in the caller to keep from leaking these into the main shell session
define_prompt_chars() {
# Force Unicode interpretation of chars, even under odd locales
local LC_ALL="" LC_CTYPE="en_US.UTF-8"
# 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.
