# _arguments rejects every option spec and nothing completes.

%description
Janet makes a good system scripting language, or a language to embed in
other programs. It's like Lua and GNU Guile in that regard. It has more
built-in functionality and a richer core language than Lua, but smaller
than GNU Guile or Python. However, it is much easier to embed and port
than Python or Guile.

There is a REPL for trying out the language, as well as the ability to run
script files. This client program is separate from the core runtime, so
Janet can be embedded in other programs.

Requires:       %{name}%{?_isa} = %{version}-%{release}

%description devel
Headers, the pkg-config file and the amalgamated janet.c needed to build
native Janet modules or to embed the Janet runtime in a C program.

%prep
%autosetup -n %{name}-%{version}
# examples/ ships as %%doc, so it must carry neither VCS dotfiles nor prebuilt
# artifacts. jitfn.janet documents the nasm command that regenerates hello.bin.
find examples -name '.*' -delete
rm examples/jitfn/hello.bin

%build
# git_hash lands in janet/build, which janet -v and the amalgamation report.
# Its upstream default is the placeholder string "meson".
%meson -Ddefault_library=shared -Dgit_hash=%{release}
%meson_build
# doc.html is a declared meson target, just not a default one.
%{__meson} compile -C %{_vpath_builddir} docs
# gendoc stamps wall-clock time, which would make the payload differ per build.
sed -i 's|<p>Generated [^<]*</p>||' %{_vpath_builddir}/doc.html
