[BoolmanO]

• Add support pywal16cols
• Add private function for check is user using pywal16cols

The problem is in different "wal" functions API.

pywal16cols

def cache_fname(img, backend, cols16, light, cache_dir, sat=""):

standard pywal

def cache_fname(img, backend, light, cache_dir, sat=""):

line 20: fc-list: command not found This means you have not installed fontconfig as a package. It is not a standard package for a Mac system, but is a very common package on Linux. You can install it with homebrew: brew install fontconfig I got this far, but I am getting no display of icons, myself. I get a squarebox with a question mark in it
Terminal: iTerm2 Shell: bash (homebrew latest bash, 5.1.16) macOS: Monterey 12.5 on M1

Same issue I'm just seeing the glyphs as text:

firacode (116 glyphs):
\uee2d  \uee2e  \uee2f  \uee30  \uee31  \uee32  \uee33  \uee34  \uee35  \uee36

Please read the first issue of this project: https://github.com/sebastiencs/icons-in-terminal/issues/1

This is duplicated.

In short you will need both fontconfig and double clicking the font install to Apple's font book for macos. For kitty I configure sth like this: symbol_map U+E000-U+EEA0 icons-in-terminal.

Use an alternative script in https://github.com/sebastiencs/icons-in-terminal/issues/1 for testing. It should still work, see my answer here: https://github.com/sebastiencs/icons-in-terminal/issues/52#issuecomment-1786613456
