module OpamSolution

: sig

Applying solver solutions

#
val resolve : ?verbose:bool -> OpamState.state -> OpamTypes.user_action -> requested:OpamTypes.name_set -> orphans:OpamTypes.package_set -> OpamTypes.atom OpamTypes.request -> (OpamSolver.solution, OpamCudf.conflict) OpamTypes.result

Resolve an user request

#
val apply : ?ask:bool -> OpamState.state -> OpamTypes.user_action -> requested:OpamPackage.Name.Set.t -> OpamSolver.solution -> OpamTypes.solver_result

Apply a solution returned by the solver. If ask is not specified, prompts the user whenever the solution isn't obvious from the request

#
val resolve_and_apply : ?ask:bool -> OpamState.state -> OpamTypes.user_action -> requested:OpamPackage.Name.Set.t -> orphans:OpamTypes.package_set -> OpamTypes.atom OpamTypes.request -> OpamTypes.solver_result

Call the solver to get a solution and then call apply. If ask is not specified, prompts the user whenever the solution isn't obvious from the request

#
val check_solution : OpamState.state -> OpamTypes.solver_result -> unit

Raise an error if no solution is found or in case of error.

Atoms

#
val eq_atom : OpamTypes.name -> OpamTypes.version -> OpamTypes.atom

Return an atom with a string version constraint

#
val atom_of_package : OpamTypes.package -> OpamTypes.atom

Return a simple atom, with no version constrain, from a package

#
val atoms_of_packages : OpamTypes.package_set -> OpamTypes.atom list

Return a list of simple atoms (ie. with no version constraints) from a set of packages

#
val eq_atoms_of_packages : OpamTypes.package_set -> OpamTypes.atom list

Return a list of constrained atoms from a set of packages

#
val check_availability : ?permissive:bool -> OpamState.state -> OpamPackage.Set.t -> OpamTypes.atom list -> unit

Checks that the atoms can possibly be verified (individually) in a package set. Displays an error and exits otherwise. permissive just changes the error message.

#
val sanitize_atom_list : ?permissive:bool -> OpamState.state -> OpamTypes.atom list -> OpamTypes.atom list

Takes a "raw" list of atoms (from the user), and match it to existing packages. Match packages with the wrong capitalisation, and raises errors on non-existing packages, and unavailable ones unless permissive is set. Exits with a message on error.

#
val sum : OpamTypes.stats -> int
