# Source build of GNU Emacs 31.1 from the official ftp.gnu.org tarball, kept
# in this repo because Fedora ships no pgtk emacs and the halcyon image wants
# the maintainer's exact configuration: pure-GTK Wayland windowing (gtk3),
# cairo drawing, harfbuzz shaping, libsystemd sd_notify, dynamic modules,
# tree-sitter and ahead-of-time native compilation (native-compilation=aot
# compiles every Lisp file during the build — expect a long Copr build;
# preloaded .eln live under /usr/lib/emacs/31.1/native-lisp, matching the
# libexecdir=/usr layout of the manual recipe).
# Beyond the explicit flags the build auto-enables whatever the BuildRequires
# provide: gnutls, dbus, gpm, gmp bignums, sqlite, the built-in JSON parser,
# svg/webp/tiff/jpeg/png/gif image support and ALSA sound.
# Sweep: custom_emacs_pgtk in ci/sweep/custom.py (emacs-mirror/emacs tags are
# "emacs-<version>" and pretest tarballs live on alpha.gnu.org, so tags are
# ranked with rpmvercmp and the ftp.gnu.org tarball is HEAD-probed zotero-style).
# Registration: ci/packages.toml (batch 0 — every BuildRequire is Fedora-side).

%description
GNU Emacs is an extensible, customizable text editor and computing
environment. This is the pure-GTK (pgtk) build: it renders through GTK 3 and
runs natively on Wayland (and X11 via XWayland) with no X toolkit dependency,
configured with cairo drawing, harfbuzz text shaping, dynamic modules,
tree-sitter parsing and ahead-of-time native compilation of the Lisp tree,
so package Lisp ships pre-compiled with no deferred compilation on first use.
