opam package file access.
Normally opam metadata access is only needed at distribution
time and this is handled by Topkg_care.Opam.File
using the
opam-format
library.
However there is one case where we want to be able to access
the metadata from Topkg
: on pin builds where the
watermarking process needs to be run to turn
the repo into a pseudo-distribution.
Since we don't want Topkg
to have any dependency and that
opam
currently doesn't allow to consult the fields of arbitrary
opam files (see
issue #2446) we
assume a pin build has the topkg
tool installed and call
to it to get the opam fields for watermarking (if topkg
is
unavailable the watermarks are simply undefined).
typet =
(string * string list) list
The type for a simplified model the fields of an opam
file. See Topkg_care.Opam.File
.
val codec : t Topkg.Private.Codec.t
codec
is a codec for opam file fields.
val fields : Topkg.fpath -> (string * string list) list Topkg.result
fields file
are the fields of the opam file file
which
are obtained by calling the topkg
topkg executable.
