DESCRIPTION="C library for processing UTF-8 encoded Unicode data"
HOMEPAGE="https://github.com/JuliaStrings/utf8proc"
# The test suite checks against the Unicode conformance data, which upstream's
# CMake otherwise file(DOWNLOAD)s at configure time (breaks under
# FEATURES=network-sandbox). -test-no-download.patch reads it from the source
# root instead; src_prepare supplies it from app-i18n/unicode-data.
SRC_URI="https://github.com/JuliaStrings/utf8proc/archive/v${PV}.tar.gz -> ${P}.tar.gz"
S="${WORKDIR}/${P}"

# The generated utf8proc_data.c (Unicode Character Database derived) is compiled
# into libutf8proc.so; upstream LICENSE.md licenses that data under the Unicode
# Data Files and Software License (Gentoo "Unicode-DFS-2015" token).
LICENSE="MIT Unicode-DFS-2015"
# subslot = SONAME major of libutf8proc.so (currently .3, diverges from PV 2.x);
# re-derive from `objdump -p` on each bump.
