  Stdlib.Lexing.lexbuf ->
  Ast.full_module * Expand.original_types

Read an ATD file from a lexbuf. See also read_channel, load_file and load_string.

If expand is true, the second part of the return value will contain a hash table mapping the types generated during monomorphization back to their original polymorphic types. See Expand.original_types for more information about this table. If expand is false, the value will be the empty hash table.

parameter annot_schema
Check for misplaced annotations in the ATD input.

parameter expand
Perform monomorphization by creating specialized type definitions starting with an underscore. Default is false. See also Expand. This corresponds to the -x option of atdcat.

parameter keep_poly
Preserve left-hand-side of all original type definitions instead of removing parametrized definitions. This option only applies when expand = true. Default is false. See also Expand. This corresponds to the -xk option of atdcat.

parameter xdebug
Debugging option producing meaningful but non ATD-compliant type names when new types names are created. Default is false. This corresponds to the -xd option of atdcat.

parameter inherit_fields
Expand inherit statements in record types. Default is false. See also Atd_inherit. This corresponds to the -if option of atdcat.

parameter inherit_variants
Expand inherit statements in sum types. Default is false. See also Atd_inherit. This corresponds to the -iv option of atdcat.

parameter pos_fname
Set the file name for use in error messages. Default is "".

parameter pos_lnum
Set the number of the first line for use in error messages. Default is 1.

val read_channel : 
  ?annot_schema:Annot.schema ->
  ?expand:bool ->
  ?keep_poly:bool ->
  ?xdebug:bool ->
  ?inherit_fields:bool ->
  ?inherit_variants:bool ->
  ?pos_fname:string ->
  ?pos_lnum:int ->
  Stdlib.in_channel ->
  Ast.full_module * Expand.original_types

Read an ATD file from an in_channel. Options: see read_lexbuf. The default pos_fname is set to "<stdin>" when appropriate.

val load_file : 
  ?annot_schema:Annot.schema ->
  ?expand:bool ->
  ?keep_poly:bool ->
  ?xdebug:bool ->
  ?inherit_fields:bool ->
  ?inherit_variants:bool ->
  ?pos_fname:string ->
  ?pos_lnum:int ->
  string ->
  Ast.full_module * Expand.original_types

Read an ATD file. Options: see read_lexbuf. The default pos_fname is the given input file name.

val load_string : 
  ?annot_schema:Annot.schema ->
  ?expand:bool ->
  ?keep_poly:bool ->
  ?xdebug:bool ->
  ?inherit_fields:bool ->
  ?inherit_variants:bool ->
  ?pos_fname:string ->
  ?pos_lnum:int ->
  string ->
  Ast.full_module * Expand.original_types

Read ATD data from a string. Options: see read_lexbuf.

val tsort : Ast.module_body -> (bool * Ast.module_body) list

Topological sort for dependency analysis. tsort splits definitions into mutually-recursive groups, ordered such that each group may only depend on type definitions of its own group or previous groups. The boolean flags indicate groups of one or more mutually recursive definitions.
