# Slackware build script for rename.pl

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

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

# This replaces the former perl-rename from the SBo repo. The
# maintainer of perl-rename asked me to take over the build, and I
# decided I like the name "rename.pl" better. Also, the old one was in
# the perl/ category, implying it was a perl library. It's not. Just
# because an application is *written* in perl, doesn't mean it should
# be in the perl/ category (same goes for python/, people).

# This is a completely new SlackBuild (shares no code with
# perl-rename.SlackBuild).

# This is the "classic" rename, that used to ship with the perl source
# ages ago. It's also the same "rename" as Debian used to ship. I'm
# aware of the existence of https://metacpan.org/release/File-Rename
# but it's not the same: it's missing a lot of options (--no-stdin,
# -i, -l, -v, and all the options relating to backups). It also
# added some new options that do look useful (-0, -d, -e, -E), but it
# doesn't look like a good tradeoff to me.

# There's also a completely different rename.pl here:
# https://github.com/kugland/rename.pl
# ...which AUR ships at version 2.0.0, so repology keeps telling me
# this is outdated. Wish there were a way to fix that.

# Since the name "rename" conflicts with util-linux, I've named this
# rename.pl, and gone to some trouble to make sure its documentation
# refers to rename.pl consistently (particularly the example commands,
# which wouldn't work if you copy/pasted them as-is).

# This version of rename is still actively maintained, as of 20230226.

# 20230905 bkw: updated for v1.14, tweak man page, add shell completions.
# 20221228 bkw: updated for v1.12, fix PKGTYPE assignment.
