#zlolcat 😸

it's a speedy and pretty little lolcat.

originally based on clolcat, now it has diverged in some ways:

• multibyte characters and grapheme clusters are supported properly.
• LCH colorspace is used for a more pleasant and accessible output.
• parameters for luminance and chroma.
• parameter for handling of ambiguous width characters.
• yet over twice as fast in typical use, as measured by hyperfine on various inputs.

compared to other great implementations that support unicode properly, zlolcat is 400%-1200% faster in typical use, but slower on some edge-cases.

#building

install latest zig and do zig build install --prefix ~/.local -Doptimize=ReleaseFast.

#usage

install the program in your $PATH, and invoke zlolcat with something on stdin, or zlolcat file1 file2.

use zlolcat -h to see all the options. to randomise the rainbow phase, you can plug a random source in like zlolcat -s$RANDOM.

#acknowledgments

• unicode support is thanks to ziglyph.
• argument parsing is thanks to clap.
