opam-format 2.2.1 (latest)

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

val pos_null : OpamParserTypes.FullPos.pos

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

val nullify_pos_value : 
  OpamParserTypes.FullPos.value ->
  OpamParserTypes.FullPos.value

val pos_best : 
  OpamParserTypes.FullPos.pos ->
  OpamParserTypes.FullPos.pos ->
  OpamParserTypes.FullPos.pos

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

val pos_file : OpamTypes.filename -> OpamParserTypes.FullPos.pos

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 op_of_raw : 
  OpamParserTypes.FullPos.env_update_op_kind ->
  OpamTypes.euok_writeable OpamTypes.env_update_op_kind

val raw_of_op : 
  OpamTypes.euok_writeable OpamTypes.env_update_op_kind ->
  OpamParserTypes.FullPos.env_update_op_kind

val string_of_path_format : OpamTypes.path_format -> string

val char_of_separator : OpamTypes.separator -> char
