Module `OpamSolver`

SAT-solver for package dependencies and conflicts

module Action : OpamActionGraph.ACTION with type package = OpamTypes.package

module ActionGraph : OpamActionGraph.SIG with type package = OpamTypes.package

type solution

val empty_universe : OpamTypes.universe

Solver

val string_of_request : OpamTypes.atom OpamTypes.request -> string

Convert a request to a string

val stats : solution -> OpamTypes.stats

Compute statistics about a solution

val new_packages : solution -> OpamTypes.package_set

Return the new packages in the solution

val string_of_stats : OpamTypes.stats -> string

Pretty-printing of statistics

val solution_is_empty : solution -> bool

Is the solution empty ?

val print_solution : 
  messages:(OpamTypes.package -> string list) ->
  rewrite:(OpamTypes.package -> OpamTypes.package) ->
  requested:OpamTypes.name_set ->
  solution ->
  unit

Display a solution

val cudf_versions_map : 
  OpamTypes.universe ->
  OpamTypes.package_set ->
  int OpamPackage.Map.t

Computes an opam->cudf version map from a set of package

val load_cudf_universe : 
  ?depopts:bool ->
  build:bool ->
  OpamTypes.universe ->
  ?version_map:int OpamTypes.package_map ->
  OpamTypes.package_set ->
  Cudf.universe

Creates a CUDF universe from an OPAM universe, including the given packages

val resolve : 
  ?verbose:bool ->
  OpamTypes.universe ->
  orphans:OpamTypes.package_set ->
  OpamTypes.atom OpamTypes.request ->
  (solution, OpamCudf.conflict) OpamTypes.result

Given a description of packages, return a solution preserving the consistency of the initial description.

val get_atomic_action_graph : solution -> ActionGraph.t

Returns the graph of atomic actions (rm, inst) from a solution

val installable : OpamTypes.universe -> OpamTypes.package_set

Keep only the packages that are installable.

val dependencies : 
  depopts:bool ->
  build:bool ->
  installed:bool ->
  ?unavailable:bool ->
  OpamTypes.universe ->
  OpamTypes.package_set ->
  OpamTypes.package list

Return the topological sort of the transitive dependency closures of a collection of packages.

val reverse_dependencies : 
  depopts:bool ->
  build:bool ->
  installed:bool ->
  ?unavailable:bool ->
  OpamTypes.universe ->
  OpamTypes.package_set ->
  OpamTypes.package list

Same as dependencies but for reverse dependencies

val check_for_conflicts : OpamTypes.universe -> OpamCudf.conflict option

Check the current set of installed packages in a universe for inconsistencies

val dump_universe : OpamTypes.universe -> out_channel -> unit

Dumps a cudf file containing all available packages in the given universe, plus version bindings (as '#v2v' comments) for the other ones.

val filter_solution : (OpamTypes.package -> bool) -> solution -> solution

Filters actions in a solution. Dependents of a removed actions are removed to keep consistency
