Powerline Multiline Theme

A colorful multiline theme, where the first line shows information about your shell session (divided into two parts, left and right), and the second one is where the shell commands are introduced.

IMPORTANT: This theme requires that a font with the Powerline symbols needs to be used in your terminal emulator, otherwise the prompt won't be displayed correctly, i.e. some of the additional icons and characters will be missing. Please follow your operating system's instructions to install one of the fonts from the above link and select it in your terminal emulator.

Provided Information

• Current path
• Current username and hostname
• Current time
• An indicator when connected by SSH
• An indicator when sudo has the credentials cached (see the sudo manpage for more info about this)
• An indicator when the current shell is inside the Vim editor
• Battery charging status (depends on the [../../plugins/available/battery.plugin.bash](battery plugin))
• SCM Repository status (e.g. Git, SVN)
• The current Python environment (Virtualenv, venv, and Conda are supported) in use
• The current Ruby environment (rvm and rbenv are supported) in use
• Last command exit code (only shown when the exit code is greater than 0)

Configuration

This theme is pretty configurable, all the configuration is done by setting environment variables.

User Information

By default, the username and hostname are shown on the right hand side, but you can change this behavior by setting the value of the following variable:

export POWERLINE_PROMPT_USER_INFO_MODE="sudo"

For now, the only supported value is sudo, which hides the username and hostname, and shows an indicator when sudo has the credentials cached. Other values have no effect at this time.

Clock Format

By default, the current time is shown on the right hand side, you can change the format using the following variable:

export THEME_CLOCK_FORMAT="%H:%M:%S"

The time/date is printed by the date command, so refer to its man page to change the format.

Segment Order

The contents of both prompt sides can be "reordered", all the "segments" (every piece of information) can take any place. The currently available segments are:

• aws_profile - Show the current value of the AWS_PROFILE environment variable
• battery - Battery information (you'll need to enable the battery plugin)
• clock - Current time in HH:MM:SS format
• cwd - Current working directory including full folder hierarchy (c.f. wd)
• hostname - Host name of machine
• in_vim - Show identifier if running in :terminal from vim
• last_status - Exit status of last run command
• python_venv - Python virtual environment information (virtualenv, venv and conda supported)
• ruby - Current ruby version if using rvm
• node - Current node version (only nvm is supported)
• scm - Version control information, git
• user_info - Current user
• wd - Working directory, like cwd but doesn't show the full folder hierarchy, only the directory you're currently in.

Two variables can be defined to set the order of the prompt segments:

export POWERLINE_LEFT_PROMPT="scm python_venv ruby cwd"
export POWERLINE_RIGHT_PROMPT="in_vim clock battery user_info"

The example values above are the current default values, but if you want to remove anything from the prompt, simply remove the "string" that represents the segment from the corresponding variable.

Padding

To get the length of the left and right segments right, a padding value is used. In most cases, the default value (2) works fine, but on some operating systems, this needs to be adjusted. One example is macOS High Sierra, where the default padding causes the right segment to extend to the next line. On macOS High Sierra, the padding value needs to be changed to 3 to make the theme look right. This can be done by setting the POWERLINE_PADDING variable before Bash-it is loaded, e.g. in your ~/.bash_profile or ~/.bashrc file:

export POWERLINE_PADDING=3
