This project is a fork from https://github.com/jimeh/git-aware-prompt/ initialy focused only in the Git context.
There are several command line tools that uses some context and for many times can lead us to errors if we don't pay attention for the context we are executing those commands.
For example, constantly switching git branches can be confusing though as you have to run git status
to see which branch you're currently on. The same for the current kubernetes context we are using. If we are working with multiples cluster and namespaces we can apply or delete a configuration in the wrong cluster and you have to run kubectl config current-context
to see the context you are.
The solution to this is to have your terminal prompt display the current branch. There's a number of articles available online about how to achieve this. This project is an attempt to make an easy to install/configure solution.
If you cd
to a Git working directory, you will see the current Git branch name displayed in your terminal prompt. When you're not in a Git working directory, your prompt works like normal.
The same if you have a KUBECONFIG environment variable set or a file ~/.kube/config
/
wget -qO- https://raw.githubusercontent.com/byjg/context-aware-prompt/master/install.sh | bash
If you want to install only git
or only k8s
context prompts just call:
wget -qO- https://raw.githubusercontent.com/byjg/context-aware-prompt/master/install.sh | bash -s git
or
wget -qO- https://raw.githubusercontent.com/byjg/context-aware-prompt/master/install.sh | bash -s k8s
Clone the project to a .bash
folder in your home directory:
mkdir ~/.bash
cd ~/.bash
git clone git://github.com/byjg/context-aware-prompt.git
Edit your ~/.bash_profile
or ~/.profile
and add the following to the top:
export CONTEXT_AWARE_PROMPT=~/.bash/context-aware-prompt
source "${CONTEXT_AWARE_PROMPT}/main.sh"
Once installed, there will be new $git_branch
, $git_dirty
and k8s_config
variables available to use in the PS1
environment variable, along with a number of color helper variables which you can see a list of in colors.sh.
If you want to know more about how to customize your prompt, I recommend this article: How to: Change / Setup bash custom prompt (PS1)
Below are a few suggested prompt configurations. Simply paste the code at the end of the same file you pasted the installation code into earlier.
export PS1="\u@\h \w \[$txtcyn\]\$git_branch\[$txtred\]\$git_dirty\[$txtrst\]\$ "
Optionally, if you want a nice pretty prompt when using sudo -s
, also add this line:
export SUDO_PS1="\[$bakred\]\u@\h\[$txtrst\] \w\$ "
Standard:
export PS1="\${debian_chroot:+(\$debian_chroot)}\u@\h:\w \[$txtylw\]\$k8s_config\[$txtrst\]\[$txtcyn\]\$git_branch\[$txtred\]\$git_dirty\[$txtrst\]\$ "
Colorized:
export PS1="\${debian_chroot:+(\$debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\] \[$txtylw\]\$k8s_config\[$txtrst\]\[$txtcyn\]\$git_branch\[$txtred\]\$git_dirty\[$txtrst\]\$ "
Assuming you followed the default installation instructions and cloned this repo to ~/.bash/context-aware-prompt
:
cd ~/.bash/context-aware-prompt
git pull
If you installed using the install.sh
you can remove the configuration and call the install
with the new configuration:
# Uninstall
~/.bash/context-aware-prompt/uninstall.sh
# Add new configuration
~/.bash/context-aware-prompt/install.sh [git|k8s|all]
