BLÅHAJ

Gay sharks at your local terminal

What is BLÅHAJ?

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.

FAQ

Why are only striped flags allowed?

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.

Why are the stripes repeating instead of showing the flag in full?

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.

I would like to add a color scheme or flag

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

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

Pipe, individual characters instead of rows (-i)

Read from file, background instead of foreground (-b), individual words instead of rows (-w)

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

Pipe, default color scheme

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.

Custom flags at runtime

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)
