%description
Nimony is a new Nim implementation under active development. This package
tracks its master branch and includes the compiler's private supporting tools.

%prep
# The checkout must be named `nimony`: the sibling's nim.cfg reaches back into
# it through a relative `../../../nimony/src/lib` path.
%autosetup -c -T -n nimony
git clone -q --depth 1 https://github.com/nim-lang/nimony.git .

# arkham and nifasm are built from the sibling nativenif repo, which
# `hastur build all` only picks up when that checkout lives next to Nimony.
# Clone it here and put it on the commit the Nimony tree pins.
git clone -q https://github.com/nim-lang/nativenif ../nativenif
nativenif_commit=$(awk 'NR == 1 {print $1}' src/nativenif.commit)
git -C ../nativenif checkout -q --detach "$nativenif_commit"

# Build hastur with Fedora's paired compiler and linker flags. Its child tool
# builds use Hastur's normal upstream commands, just like Koch above.
