Apart from a cute cuddly shark plushie from IKEA, BLÅHAJ is a lolcat-like CLI tool that colorizes your input, shows flags and prints colorful sharks!

It has a wide variety of flags/colors to choose from and many options from flag size to whether to colorize by line, word or character.

You can download one of the statically-linked pre-built binaries from the releases page.

They are built & published by our lovely actions.

Arch Linux users can install the blahaj (or the blahaj-git) AUR package.

docker run --rm -it --name blahaj ghcr.io/geopjr/blahaj -h

• crystal - 1.8.0

• $ make (or $ make static on Alpine Linux for a static build)
• # make install

Flags with eg. triangles, circles or symbols, need enough horizontal space to determine where and how to display them. BLÅHAJ can't know in advance how long the input is going to be.

Just like the previous question, BLÅHAJ can't know how long the text is going to be (vertically) since it colorizes the input as it comes in.

Great! Follow the Contributing section and modify data/colors.yaml.

flag name:
  color:
    - hex color
    - per
    - stripe
  alias:
    - aliases
    - if any

Notice how the foreground color changes based on the background color.

All images above include ALT text and you are encouraged to read it, if you find parts of them confusing, by using screen readers, hovering over them with your cursor or looking at the source.

You can pass a local ./data/colors.yaml file at runtime to the BLAHAJ_COLORS_YAML env var and BLÅHAJ will parse it. This can also be used to override the already defined flags.

(The custom file needs to follow the ./data/colors.yaml format)
