Bash prompt with git info

A simple and beautiful bash prompt that also prints command execution time, venv, git, aws, and k8s information.

• Shows if a git fetch has not been run for 15 minutes with ☇ character
• Summarizes git status with single letters
• Shows number of ahead / behind commits with remote branch as f.e. ↑1 ↓1
• Shows the current branch
• Username included in red if running as root
• Shows virtual environment name if one is activated
• Highlights the prompt with a red ⑉ if the exit status of a command > 0
• Configurable host nickname, if not set hostname will be shown
• Can display currently active AWS profile, if $AWS_PROFILE is set and user sets $SHOW_AWS_PROFILE
• Can display current Kubernetes context and namespace, enable through $SHOW_K8S and $SHOW_K8S_NS.
• Can display how long it took to run the previous command, enable by setting $SHOW_CMD_TIME.

NOTE: if the K8s context contains / in its title, only the part before / gets displayed.

Support

I use this regularly on MacOS and Linux with latest Bash and Git, no plans to support anything ancient but if you run into issues with recent versions please open an issue.
