Class type
Representation of opam packages.
The scope of package installation:
- Switch: installed with opam.
- Monorepo: locally fetched along unikernel sources.

v ~scope ~build ~sublibs ~libs ~min ~max ~pin opam
is a package
. Build
indicates a build-time dependency only, defaults to false
. The library name is by default the same as opam
, you can specify ~sublibs
to add additional sublibraries (e.g. ~sublibs:["mirage"] "foo"
will result in the library names ["foo"; "foo.mirage"]
. In case the library name is disjoint (or empty), use ~libs
. Specifying both ~libs
and ~sublibs
leads to an invalid argument. Version constraints are given as min
(inclusive) and max
(exclusive). If pin
is provided, a pin-depends is generated, pin_version
is "dev"
by default. ~scope
specifies the installation location of the package.
val name : t -> string
name t
is t
's opam name.
val key : t -> string
key t
is t
's key (concatenation of name and installation scope).
val pin : t -> (string * string) option
pin t
is Some (name_version, r)
iff t
is pinned to the repository r
.
val build_dependency : t -> bool
build_dependency t
is true
iff t
is a build-time dependency.
val libraries : t -> string list
libraries t
is the set of libraries (and sub-libraries) used in the package t
. For most packages, it will only contain one library whose name is name t
.
val max_versions : t -> string list
max_versions
is the set of maximum versions of t
which are required.
val min_versions : t -> string list
min_versions
is the set minimum versions of t
which are required.
merge x y
is merges the information of x
and y
. The result is None
if name x != name y
.
val pp : ?surround:string -> t Fmt.t
pp
is the pretty-printer for packages.
