Helper functions on the base types (from OpamTypes)

This module contains basic utility functions and stringifiers for the basic OPAM types present in OpamTypes.ml

val string_of_std_path : OpamTypes.std_path -> string
val std_path_of_string : string -> OpamTypes.std_path
val all_std_paths : OpamTypes.std_path list
val action_contents : [< 'a OpamTypes.action ] -> 'a list

Extract a package from a package action.

val map_atomic_action : ('a -> 'b) -> 'a OpamTypes.atomic_action -> 'b OpamTypes.atomic_action
val map_highlevel_action : ('a -> 'b) -> 'a OpamTypes.highlevel_action -> 'b OpamTypes.highlevel_action
val map_concrete_action : ('a -> 'b) -> 'a OpamTypes.concrete_action -> 'b OpamTypes.concrete_action
val map_action : ('a -> 'b) -> 'a OpamTypes.action -> 'b OpamTypes.action
val full_action_contents : 'a OpamTypes.action -> 'a list

Extract a packages from a package action. This returns all concerned packages, including the old version for an up/down-grade.

val string_of_cause : ('pkg -> string) -> 'pkg OpamTypes.cause -> string

Pretty-prints the cause of an action

val string_of_shell : OpamTypes.shell -> string

Pretty-print

The empty file position

val nullify_pos : 'a -> 'a OpamParserTypes.FullPos.with_pos
val nullify_pos_map : ('a -> 'b) -> 'a OpamParserTypes.FullPos.with_pos -> 'b OpamParserTypes.FullPos.with_pos

pos_best pos1 pos2 returns the most detailed position between pos1 and pos2 (defaulting to pos1)

Position in the given file, with unspecified line and column

val string_of_pos : OpamParserTypes.FullPos.pos -> string

Prints a file position

val string_of_user_action : OpamTypes.user_action -> string
val env_array : OpamTypes.env -> string array

Makes sure to keep only the last binding for a given variable; doesn't preserve order

exception Parse_variable of string * string
val filter_ident_of_string : string -> OpamTypes.name option list * OpamTypes.variable * (string * string) option

Parses the data suitable for a filter.FIdent from a string. May raise Failure msg on bad package names. A self-reference _ parses to None

val filter_ident_of_string_interp : ?accept:bool -> string -> OpamTypes.name option list * OpamTypes.variable * (string * string) option

Like Filter_ident_of_string but parses also '%?pkg+:var:% syntax for variables with package name that contains a '+'. if accept is false, Parse_variable (pkg,var) is raised when several '+' are encountered in package name, i.e. 'pkg++:var'.

val string_of_filter_ident : (OpamTypes.name option list * OpamTypes.variable * (string * string) option) -> string
val pkg_flag_of_string : string -> OpamTypes.package_flag
val string_of_pkg_flag : OpamTypes.package_flag -> string
val all_package_flags : OpamTypes.package_flag list
val map_success : ('a -> 'b) -> ('a, 'fail) OpamTypes.result -> ('b, 'fail) OpamTypes.result

Map on a solver result

val iter_success : ('a -> unit) -> ('a, 'b) OpamTypes.result -> unit
val env_update : ?comment:string -> rewrite:'a OpamTypes.separator_path_format option -> string -> 'b OpamTypes.env_update_op_kind -> string -> ('a, 'b) OpamTypes.env_update

Environment update helpers

val env_update_resolved : ?comment:string -> ?rewrite:OpamTypes.spf_resolved OpamTypes.separator_path_format option -> string -> 'a OpamTypes.env_update_op_kind -> string -> (OpamTypes.spf_resolved, 'a) OpamTypes.env_update
val env_update_unresolved : ?comment:string -> ?rewrite:OpamTypes.spf_unresolved OpamTypes.separator_path_format option -> string -> 'a OpamTypes.env_update_op_kind -> string -> (OpamTypes.spf_unresolved, 'a) OpamTypes.env_update
val string_of_path_format : OpamTypes.path_format -> string
val char_of_separator : OpamTypes.separator -> char
