# Flow Control, tracking the upstream master branch.
#
# The v0.7.2 release tag targets Zig 0.15.2; master is the only branch that
# builds with Zig 0.16 (see minimum_zig_version in build.zig.zon), which is
# what this repo's COPR has. Hence a master snapshot rather than the tag.
#
# build.zig.zon pins a set of git/URL dependencies (flow-syntax plus the
# tree-sitter parsers it bundles, vaxis, zeit, ...) that Zig fetches over the
# network at build time. The COPR builder has network access, as for the
# other Zig packages in this repo.
#
# The default Linux build is a statically linked (musl) binary.

%description
Flow Control is a fast, feature-rich text editor that runs in the terminal.
It provides tabs, multiple cursors, full mouse support, syntax highlighting
for more than 70 languages via tree-sitter, LSP integration and several
pre-configured keybinding modes (Flow Control, Emacs, Vim and Helix).

This package tracks the upstream master branch.

%prep
# GitHub branch archives extract into flow-master/
%autosetup -n flow-master

# Upstream embeds the output of `git describe` in the binary. The branch
# archive has no .git, so recreate a minimal repository with a tag and an
# upstream branch to keep `flow --version` and the home screen meaningful.
