version impl
is the Opam package for impl
, if any. Virtual and dummy implementations return None
.
virtual_role impls
is a virtual package name with candidates impls
. This is used if the user requests multiple packages on the command line (the single impl
will also be virtual).
val virtual_impl :
context:Context.t ->
depends:OpamPackage.Name.t list ->
unit ->
impl
virtual_impl ~context ~depends
is a virtual package which just depends on depends
. This is used if the user requests multiple packages on the command line - each requested package becomes a dependency of the virtual implementation.
val package_name : Role.t -> OpamPackage.Name.t option
package_name role
is the Opam package name for role
, if any. Return None
on virtual roles.
val formula :
restriction ->
[ `Ensure | `Prevent ] * OpamFormula.version_formula
formula restriction
returns the version formula represented by this restriction along with its negation status: (`Prevent, formula)
roughly means not formula
.
