# Maintainer: A. López-Valencia <https://aur.archlinux.org/users/vorbote>
#######################################################################
# CAVEAT LECTOR: This PKGBUILD is highly opinionated. I give you
# enough rope to hang yourself, but by default it
# only enables the features I use.
#
# TLDR: yaourt users, cry me a river.
#
# Everyone else: do not update blindly this PKGBUILD. At least
# make sure to compare and understand the changes.
#
#######################################################################
#######################################################################
# Track a maintenance branch or, by default, track master.
#
# Pick a branch from the output of "git branch" ran on your local copy
# of the emacs repository.
#
# E.g.:
#
# BRANCH=master
# BRANCH=emacs-26
#
# Take note that I don't expect you to track anything different to master
# or emacs-26 for obvious reasons. (See below).
#
BRANCH=master
#######################################################################
# Assign "YES" to the variable you want enabled; empty or other value
# for NO.
#
# Where you read experimental, replace with foobar.
# =================================================
#
#######################################################################
CHECK= # Run tests. May fail, this is developement after all.
CLANG= # Use clang.
LTO= # Enable link-time optimization. Experimental.
CLI= # CLI only binary.
NOTKIT= # Use no toolkit widgets. Like B&W Twm (001d sk00l).
#
# Read https://wiki.archlinux.org/index.php/X_resources
# https://en.wikipedia.org/wiki/X_resources
# and https://www.emacswiki.org/emacs/XftGnuEmacs
# for some tips on using outline fonts with
# Xft, if you choose no toolkit or Lucid.
#
LUCID= # Use the lucid, a.k.a athena, toolkit. Like XEmacs, sorta.
GTK2= # GTK2.
GPM= # Enable gpm support.
M17N= # Enable m17n international table input support.
# You are far better off using UTF-8 and an input
# method under X/Wayland. But this gives independence
# if you need it.
OTF="YES" # OTF font support. Also a secondary dependency
# by pulling m17n-lib. Not needed in that case.
CAIRO= # Highly experimental. Maintaner dissapeared.
XWIDGETS= # Use GTK+ widgets pulled from webkit2gtk. Usable.
DOCS_HTML= # Generate and install html documentation.
DOCS_PDF= # Generate and install pdf documentation.
MAGICK= # Imagemagick 6 libraries support. Imagemagick,
# like flash, is bug ridden and won't die; yet useful.
NOGZ= # Don't compress el files.
