# Nerd Fonts Version: 3.1.1
# Script Version: 2.2.2
#
# Iterates over all [*] archived fonts
# to generate ruby cask files for homebrew-fonts (https://github.com/caskroom/homebrew-fonts)
# * Only adds non-Windows versions of the fonts
# * Needs the zip archives in archives/ (i.e. run `./archive-fonts.sh` first)
#
# Uses the current release version (including drafts) of the repo.
# You can specify a different version with the --setversion parameter.
# A leading 'v' from the version is removed.
# Must be the first parameter.
#
# [1] Accepts one parameter, a pattern which fonts to examine, if not given defaults
# to "*" which is all fonts.
#
# Example runs
# generate-casks.sh Hasklig
# generate-casks.sh --setversion 2.2.0
# generate-casks.sh Hasklig
# generate-casks.sh --setversion 2.2.0 Hasklig
