Signature

val parse_lib : Ppxlib.expression -> string option

parse_lib e is Some "foo" or None if e is a string option, and raises a located exception otherwise. Intended to be used for parsing the lib argument to the derivers.

val expand_typ : ?lib:string -> Ppxlib.core_type -> Ppxlib.expression

val derive_str : 
  plugins:Meta_deriving.Plugin.t list ->
  name:string option ->
  lib:string option ->
  (Ppxlib.rec_flag * Ppxlib.type_declaration list) ->
  Ppxlib.structure_item list

Deriver for Irmin type representations.

?name: overrides the default name of the generated type representation;

?lib: overrides the default location for the primitive Irmin typereps. ~lib:None will assume that the typereps are available in the same namespace.

val derive_sig : 
  plugins:Meta_deriving.Plugin.t list ->
  name:string option ->
  lib:string option ->
  (Ppxlib.rec_flag * Ppxlib.type_declaration list) ->
  Ppxlib.signature_item list

Deriver for Irmin type representation signatures.

Optional arguments have the same meaning as in derive_str.
