opam-state 2.1.6 · OCaml Package

Tools for manipulating and checking package definition ("opam") files

val template : OpamTypes.package -> OpamFile.OPAM.t

Create an OPAM package template filled with common options

val lint : 
  ?check_extra_files:(OpamTypes.basename * (OpamHash.t -> bool)) list ->
  ?check_upstream:bool ->
  OpamFile.OPAM.t ->
  (int * [ `Warning | `Error ] * string) list

Runs several sanity checks on the opam file; returns a list of warnings. `Error level should be considered unfit for publication, while `Warning are advisory but may be accepted. The int is an identifier for this specific warning/error. If check_extra_files is unspecified or false, warning 53 won't be checked.

val lint_file : 
  ?check_extra_files:(OpamTypes.basename * (OpamHash.t -> bool)) list ->
  ?check_upstream:bool ->
  ?handle_dirname:bool ->
  OpamFile.OPAM.t OpamFile.typed_file ->
  (int * [ `Warning | `Error ] * string) list * OpamFile.OPAM.t option

Same as lint, but operates on a file, which allows catching parse errors too. check_extra_files defaults to a function that will look for a files/ directory besides filename. handle_dirname is used for warning 4, and should be set when reading packages from a repository, so that package name and version are inferred from the filename.

val lint_channel : 
  ?check_extra_files:(OpamTypes.basename * (OpamHash.t -> bool)) list ->
  ?check_upstream:bool ->
  ?handle_dirname:bool ->
  OpamFile.OPAM.t OpamFile.typed_file ->
  in_channel ->
  (int * [ `Warning | `Error ] * string) list * OpamFile.OPAM.t option

Same as lint_file, but taking input from a channel. check_extra_files defaults to a function that will look for a files/ directory besides filename

val lint_string : 
  ?check_extra_files:(OpamTypes.basename * (OpamHash.t -> bool)) list ->
  ?check_upstream:bool ->
  ?handle_dirname:bool ->
  OpamFile.OPAM.t OpamFile.typed_file ->
  string ->
  (int * [ `Warning | `Error ] * string) list * OpamFile.OPAM.t option

Like lint_file, but takes the file contents as a string. check_extra_files defaults to a function that will look for a files/ directory besides filename

val all_lint_warnings : unit -> (int * [ `Warning | `Error ] * string) list

val warns_to_string : (int * [ `Warning | `Error ] * string) list -> string

Utility function to print validation results

val warns_to_json : 
  ?filename:string ->
  (int * [ `Warning | `Error ] * string) list ->
  OpamJson.t

Utility function to construct a json of validation results. The format is as follow: "file" : string <filename>, "result" : string (passed | error | warning), "warnings" : [ { "id" : int, "message" : string <warning message>, ... ], "errors" : { "id" : int, "message" : string <error message> }, ...

}

val read_opam : OpamTypes.dirname -> OpamFile.OPAM.t option

Read the opam metadata from a given directory (opam file, with possible overrides from url and descr files). Also includes the names and hashes of files below files/ Warning: use read_repo_opam instead for correctly reading files from repositories!

val read_repo_opam : 
  repo_name:OpamTypes.repository_name ->
  repo_root:OpamTypes.dirname ->
  OpamTypes.dirname ->
  OpamFile.OPAM.t option

Like read_opam, but additionally fills in the metadata_dir info correctly for the given repository.

val add_aux_files : 
  ?dir:OpamTypes.dirname ->
  files_subdir_hashes:bool ->
  OpamFile.OPAM.t ->
  OpamFile.OPAM.t

Adds data from 'url' and 'descr' files found in the specified dir or the opam file's metadata dir, if not already present in the opam file. if files_subdir_hashes is true, also adds the names and hashes of files found below 'files/'

val map_all_variables : 
  (OpamTypes.full_variable -> OpamTypes.full_variable) ->
  OpamFile.OPAM.t ->
  OpamFile.OPAM.t

Tools to manipulate the OpamFile.OPAM.t contents

val map_all_filters : 
  (OpamTypes.filter -> OpamTypes.filter) ->
  OpamFile.OPAM.t ->
  OpamFile.OPAM.t

val dep_formula_to_string : OpamTypes.formula -> string

Converts a dependency formula to the same format as used in opam package definition files.

val sort_opam : OpamFile.OPAM.t -> OpamFile.OPAM.t

Sort opam fields: author, tags, depexts, depends, depopts, conflicts, pin_depends, extra_files, extra_sources
