Features

Git support

The theme's git parser adds two level of git information. Firstly, it colors all common git states differently. Secondly, it gives detailed change information by displaying a variety of icons.

State Colors

• green – clean branch
• yellow – unstaged changes
• magenta – all changes are staged
• blue – there are stashed changes for this branch
• red – unmerged changes/merge conflict

Icons

• • – indexed file modified
•  – file added to index
•  – indexed file removed
•  – indexed file renamed
• 裸 – untracked file
•  – indexed file copied

SSH Support

If you are installing this theme on a ssh-machine, it automatically detects when you connect to this machine and displays a ssh symbol. You can freely choose this symbol and the bubble color for every ssh-machine that you manage, making them easily differentiable. Check the Customization section for further information.

256 Color support

This theme supports 256 colors, you can use zsh-color-codes (get a list by running the command spectrum_ls) or the traditional zsh-color-strings (e.g. 'red'). Check the Customization section for further information.

Customization

This theme is built with customization in mind. This means that you should be able to customize colors and icons aswell as add custom bubbles in the theme's style.

What to do before

Assuming you are using ohmyzsh.

Before customization please copy this theme to ohmyzsh's custom theme directory.

$ cp $ZSH/themes/bubblified.zsh-theme $ZSH/custom/themes

Then edit the theme using your favorite editor, mine is neovim.

$ nvim $ZSH/custom/themes/bubblified.zsh-theme

To load the edited theme, restart your terminal emulator or source your .zshrc.

$ source ~/.zshrc

Icons

To change icons for the default bubbles, just change their constants under the # SYMBOL CONSTANTS section.

Colors

To change colors for the default bubbles, just change their constants under the # COLOR CONSTANTS section. Valid values are {'black', 'red', 'blue', 'cyan', 'yellow', 'green', 'white', 'magenta'}, they correspond to the colors set in your terminal.

filepath_color='blue'

You can also use zsh-color-codes for a wider spectrum of 256 colors (use the command spectrum_ls for a complete list). When working with color codes, make sure that you set all three digits.

filepath_color='078'

SSH

Assuming you have installed the theme ON your SSH-MACHINE.

To change the icon and the colors (including the bubble's color) you have to customize the theme on your ssh-machine.

Custom Bubbles

Simple Bubbles

Simple bubbles are bubbles with the default bubble_color and content. Declare a variable (e.g. the current time)

time_bubble="%T"

Build a bubble by enclosing the variable with $bubble_left and $bubble_right.

time_bubble="$bubble_left%T$bubble_right"

OPTIONAL - If you want a different text color, then add an escape sequence with the color definition or achieve 256 color support by using the in-built foreground function and a zsh-color-string or a zsh-color-code.

time_bubble="$bubble_left%{$fg[red]%}%T$bubble_right"
# or
time_bubble="$bubble_left$(foreground '073')%T$bubble_right"

Add the variable to the PROMPT.

PROMPT='...$time_bubble...'

Fancy Bubbles

Fancy bubbles are in the style of the default git_bubble. They consist of multiple segments for which the text and the background can be colored individually. Define a custom function that echos the bubble's content.

foo () {
    echo -n "left middle right"
}

Use the provided bubblify function to build custom colored bubble segments.

foo () {
    echo -n "$(bubblify 0 "left" "black" "red")$(bubblify 1 "middle" "green" "black")$(bubblify "right" "yellow" "magenta")"
}

TIP - bubblify {0, 1, 2, 3} "foreground-color" "background-color" where 0 builds a left segment, 1 builds a middle segment, 2 builds a right segment and 3 builds a whole custom colored bubble with only one segment. "foreground-color" and "background-color" can be used with zsh-color-strings or zsh-color-codes.

TIP - Including %{$reset_color%} at the end of the echo will make sure that colors are reset to the default ones after your bubble finishes rendering.

Add the function as a subshell call to the PROMPT.

PROMPT='...$(foo)...'
