# Flow Control, tracking the upstream zig-0.16 branch.
#
# The v0.7.2 release tag targets Zig 0.15.2 and master now requires Zig 0.17
# (see minimum_zig_version in build.zig.zon). Fedora has Zig 0.16 but not 0.17,
# so this tracks the upstream zig-0.16 maintenance branch, which pins
# minimum_zig_version = 0.16.0.
#
# 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 zig-0.16 branch.

%prep
# GitHub branch archives extract into flow-zig-0.16/
%autosetup -n flow-zig-0.16

# 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.
