opam filesmodule File : sig ... endopam file generation.
These metadata keys can be specified to define opam file fields. Some of the metadata is covered by standard keys. The full map is documented in File.pkg_of_meta.
The type for package specifications. A package name and a filtered package formula, use "" if you don't have any constraint.
val tag : bool B0_meta.keytag indicates the entity is related to opam. Adding this tag to a pack makes it represent an opam package for b0's opam tooling.
val available : string B0_meta.keyavailable is an opam available: field value. This is a raw string in opam sntax that defines the whole field.
val build : string B0_meta.keybuild is an opam build: field value. This is a raw string in opam syntax that defines the whole field. Used to override automatic opam file generation, see pkg_meta_of_pack.
val depends : pkg_spec list B0_meta.keydepends is an opam depends: field value. Used to override automatic opam file dependency generation, see pkg_meta_of_pack.
val depopts : pkg_spec list B0_meta.keydepopts is an opam depopts: field value.
val conflicts : pkg_spec list B0_meta.keyconflicts is an opam conflicts: field value.
val file_addendum : File.t B0_meta.keyfile_addendum is an opam file fragment appended at the end of a generated opam file. See B0_opam.File.pkg_of_meta.
val install : string B0_meta.keyinstall is an opam install: field value. This is a raw string in opam syntax that defines the whole field. Used to override automatic opam file generation, see pkg_meta_of_pack.
val name : string B0_meta.keyname is an opam name: field value. Use to override automatic opam package name generation, see pkg_meta_of_pack.
val pin_depends : (string * string) list B0_meta.keypin_depends is an opam pin-depends: field value.
val pkg_name_of_pack : B0_pack.t -> stringpkg_name_of_pack p derives an opam package name for p. This is either in order:
name field of p's meta, if defined.B0_pack.basename of p if not equal to "default".p's scope directory.pkg_meta_of_pack p is opam package metadata for pack p ready to be used with File.pkg_of_meta to derive an opam package file.
This is p's metadata with the following fields added if they are unspecified:
name, the value of B0_opam.pkg_name_of_pack p.B0_meta.synopsis and B0_meta.description. The fields are tentatively derived using B0_pack.derive_synopsis_and_description.build, a locked b0 build of the pack is defined.depends, we collect the OCaml libraries required by units in the pack, derive a package names out of them. FIXME. This is the poc but it's not workable for now we don't have enough metadata in library names..opam unitval unit : B0_unit.tunit is the unit of the .opam action.
See b0 -- .opam --help and the b0 opam manual for more information.
