# Slackware build script for mdcat-bin

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# This is a binary repack because the source is in Rust, and won't
# build with the Rust that ships with Slackware 15.0. It would be
# possible for someone to use rustup and deal with "cargo vendor"
# stuff to create build-from-source mdcat SlackBuild, but that
# someone will not be me. If you are that someone, I've named this one
# "mdcat-bin" so you can name yours "mdcat".

# Despite the "musl" in the tarball filename, this works fine on
# Slackware, since it's 100% statically linked. Upstream probably used
# musl because glibc's not capable of creating a truly static binary
# that uses DNS...

# Many thanks to chrisdent and pwshdooduk of libera.chat's #powershell,
# for making sense of the powershell completions and just generally
# being friendly folks.

# 20260712 bkw:
# - updated for v2.5.0.
# Newer releases exist, but they require a newer glibc than Slackware
# 15.0 has. I don't use this often enough to jump through hoops to get
# a new version working, so this is it for 15.0.
