# 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](https://iterm2.com/) over Terminal.app - | |
# it has significantly better color fidelity. | |
# | |
# If using with "light" variant of the Solarized color schema, set | |
# SOLARIZED_THEME variable to "light". If you don't specify, we'll assume | |
# you're using the "dark" variant. | |
# | |
# # 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 | |

# 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. | |

Hi all, I started using pyenv last week and wanted to see the version of Python when I am inside a project/virtual env.
I found your file but since I am not familiar with .zshrc profiles setup, not sure what to do with it.
I already have
- powerline installed on my mac os
- my iterm 2 profile set up correctly
My question is, where should I copy this whole file to?? Should I copy the whole text and paste in my .zshrc??
Please let me know. Thank you very much.
yes, just copy it to .zshrc
