# $BUILD = Directory to temporarily install

#
# DEPS
# Required:     wayland-protocols, wayland, mesa, libinput, libxcb, libseat
# Required:     libxkbcommon, pixman, xkeyboard-config, hwdata
# Recommended:  xcb-util-renderutil, xcb-util-wm, xcb-util-image
# Optional:     xcb-errors

# As of 0.14.x, logind support was dropped in favor of libseat

# version 0.16.0 and master branch from gitlab has missing 
# headers used by wayfire. But reveting to specific commit 
# allows wayfire to build with wlroots 0.16.0

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':' except on otherwise blank lines.

wlroots:
wlroots: Pluggable, composable, unopinionated modules for building a Wayland
wlroots: compositor. It provides backends that abstract the underlying 
wlroots: display and input hardware, including KMS/DRM, libinput, Wayland, 
wlroots: X11, and headless backends, plus any custom backends you choose to 
wlroots: write, which can all be created or destroyed at runtime and used in 
wlroots: concert with each other.
