.Os
.Sh NAME
.Nm opam-module
.Nd sysutils/opam port module
.Sh DESCRIPTION
This manual page documents the behavior of setting
.Li MODULES=sysutils/opam
in the
.Xr ports 7
tree.
.Pp
The module provides helpers for packaging a program using
.Xr opam 1
(OCaml Package Manager).
.Pp
.Ev WRKSRC
is expected to contains opam packages, possibly with local customization.
All .opam files, at any depth, will be registered.
Unmodified dependencies should be omitted, which will be managed separately.
.Pp
To generate a standalone opam repository containing only the dependencies and
the sources files for compiling the specified sources tree,
the
.Xr make 1
.Cm modopam-repository
target should be used.
It downloads an opam repository from
.Ev MODOPAM_REPO_URL
(defaults to official opam repository hosted on github), using
.Ev MODOPAM_REPO_COMMIT
commit (it is preferable to explicitly specify it for reproducibility,
but "master" is the default value).
The repository is named according to the
.Ev MODOPAM_REPO_NAME
variable.
Next, the repository is stripped to contain only the build dependencies of
.Ev MODOPAM_PACKAGES_REPOSITORY
(default to
.Ev MODOPAM_PACKAGES ).
After that the repository is filled with a local cache of package archives.
The resulting directory can be packaged and distributed.
It contains source code for building the opam packages.
.Pp
External dependencies can be hinted using the
.Xr make 1
target
.Cm modopam-external .
The list of packages expected to be present at build time is shown.
.Pp
The module appends to
.Ev BUILD_DEPENDS
unless
.Ev MODOPAM_BUILDDEP
is set to `No'.
.Pp
It sets the
.Ev MODOPAM_PACKAGES
variable to
.Ev PKGSTEM ,
as the default value for opam packages to build and install.
.Pp
It sets
.Ev MODOPAM_OPAMROOT ,
.Ev MODOPAM_ENV ,
.Ev MODOPAM_OPAM_BIN
and
.Ev MODOPAM_OPAM_RUN
accordingly.
.Pp
The opam options
.Fl --with-doc
and
.Fl --with-test
are available using
.Ev MODOPAM_WITH_DOC
and
.Ev MODOPAM_WITH_TEST .
They default to `No'.
.Pp
A
.Ev CONFIGURE_STYLE
"opam" is provided.
It is initialized to opam with the opam repository at
.Ev MODOPAM_REPO_DIR
(defaults to
.Pa ${WRKDIR}/${MODOPAM_REPO_NAME} ).
It is expected to have been generated previously by the
.Cm modopam-repository
target and distributed separately.
It will also pin the opam packages present in
.Ev WRKSRC ,
possibly overriding opam packages from the repository.
.Pp
A default build target is used (except if
.Ev MODOPAM_BUILD
is set to `No'.
It uses the
.Ev MODOPAM_PACKAGES_BUILD
variable to list the opam packages to build (default to
.Ev MODOPAM_PACKAGES ).
.Pp
A default install target is used (except if
.Ev MODOPAM_INSTALL
is set to `No').
It uses the
.Ev MODOPAM_PACKAGES_INSTALL
variable to list the opam packages to install (defaults to
.Ev MODOPAM_PACKAGES ).
