# Remove a test that depends on a library that depends on jbuilder.
# Hurray for recursive dependency chains...
# Remove further tests that want 'utop' and 'odoc' to exist.
Patch0:         jbuilder-remove-unrunnable-unit-tests.patch

# Always build boot.exe using the bytecode compiler. This speeds
# up the build and fixes a build failure on ppc64.
Patch1:         https://patch-diff.githubusercontent.com/raw/ocaml/dune/pull/463.patch

BuildRequires:  ocaml >= 4.02.3
BuildRequires:  ocaml-findlib-devel

# Depend on /usr/bin/sphinx-build for python version invariance.
BuildRequires:  /usr/bin/sphinx-build

# Required by tests.
BuildRequires:  ocaml-menhir

# Jbuilder has vendored deps (ugh):
# I'm not clear on how to unbundle them.
# It seems to be unsupported upstream; the bootstrap process for jbuilder
# doesn't seem to be able to detect libraries installed systemwide.

%description
Jbuilder is a build system designed for OCaml/Reason projects only. It focuses
on providing the user with a consistent experience and takes care of most of
the low-level details of OCaml compilation. All you have to do is provide a
description of your project and Jbuilder will do the rest.

The scheme it implements is inspired from the one used inside Jane Street and
adapted to the open source world. It has matured over a long time and is used
daily by hundred of developers, which means that it is highly tested and
productive.

%prep
# Eep. Upstream is (slowly) renaming jbuilder -> dune. This has already
# affected the tarball here.
%autosetup -n dune-%{version}-%{pre_tag} -p1

# The jbuilder build script figures out if the native code compiler is available
# and uses it if it is, otherwise it uses the bytecode compiler. Thus I think
# we just need to "make" here.
%make_build release
%make_build doc

%install
# jbuilder's makefile has a "make install" target. Tragically, it uses opam-install(er)
# to install itself. Even more tragically, opam now requires jbuilder to build.
# Therefore as a workaround we can just manually install things ourselves--
# jbuilder is *mostly* just a binary, making this easy.
mkdir -p %{buildroot}%{_bindir}
mkdir -p %{buildroot}%{_libdir}/ocaml/jbuilder/
mkdir -p %{buildroot}%{_mandir}/man1

# The files to install are stored in _build as symlinks; dereference them.
cp -aL _build/install/default/bin/jbuilder %{buildroot}%{_bindir}/
cp -aL _build/install/default/lib/jbuilder/* %{buildroot}%{_libdir}/ocaml/jbuilder/
cp -aL _build/install/default/man/man1/* %{buildroot}%{_mandir}/man1

# Install documentation by way of pkgdocdir.
mkdir -p %{buildroot}%{_pkgdocdir}/
cp -ar README.md CHANGES.md doc/_build/* %{buildroot}%{_pkgdocdir}/

# Run the unit tests.
