NAME

       atdgen - ATD compiler and code generator

SYNOPSIS

       atdgen [options...] [atd-file]

DESCRIPTION

       atdgen reads ATD type definitions and generates OCaml code (both ml and mli files) for

       — type definitions (option -t)

       — serializers and deserializers for Biniou (option -b)

       — serializers and deserializers for JSON (option -j)

       — record-creating functions supporting default fields (option -v)

       — user-specified data validators (option -v)

       If  no  mode  option  (-t,  -b,  -j  or  -v) is given, then -t -b is assumed. Unless -o is
       present, the <prefix> for the generated files is derived from the  atd-file  argument.  If
       the  atd-file  argument  is  omitted,  atdgen  reads  ATD  sources from standard input, if
       additionally -o is missing, it behaves as if -o - was given.

OPTIONS

       -t     Produce files <prefix>_t.mli and <prefix>_t.ml containing  OCaml  type  definitions
              for the ATD input

       -b     Produce  files  <prefix>_b.mli  and  <prefix>_b.ml containing OCaml serializers and
              deserializers for the Biniou data format

       -j     produce files <prefix>_j.mli and <prefix>_j.ml  containing  OCaml  serializers  and
              deserializers for the JSON data format

       -v     Produce  files  <prefix>_v.mli  and  <prefix>_v.ml  containing  OCaml functions for
              creating records and validators, see also option -validate.

       -dep   Output dependencies in makefile-format for all possible  atdgen  output  files  and
              exit

       -list  Output a space-separated list of all possible atdgen output files and exit

       -o <prefix>
              set  the  <prefix>  for the options -t, -b and -j.  If <prefix> is -, atdgen writes
              code in the form of

                     struct ... end : sig ... end

              to standard output.

       -biniou
              [deprecated] same as -t -b, i.e., produce serializers and deserializers for  Biniou
              and OCaml type definitions (default)

       -json  [deprecated]  same  as  -t -j, i.e., produce serializers and deserializers for JSON
              and OCaml type definitions.

       -j-std standard JSON: Convert tuples and variants into standard JSON and refuse  to  print
              NaN and infinities. This option implies -json unless another mode is specified.

       -std-json
              [deprecated] same as -j-std

       -j-pp <func>
              Apply  the  OCaml  function  <func> of type (string -> string) to the input of each
              *_of_string function generated by atdgen (JSON mode). (This was intended for  UTF-8
              validation of the input which is not performed by atdgen.)

       -j-defaults
              Output JSON record fields even if their value is known to be the default.

       -j-strict-fields
              Call  !Ag_util.Json.unknown_field_handler for every unknown JSON field found in the
              input instead of simply skipping them. The initial value of this reference prints a
              message and raises a Failure exception.

       -j-custom-fields <func>
              Call function <func> of type (string -> unit) for every unknown JSON field found in
              the input instead of simply skipping them. See also -j-strict-fields.

       -validate
              [deprecated] same as -t -v, Produce  data  validators  from  <ocaml  validator="x">
              annotations  where  x is a user-written validator to be applied on a specific node.
              This is typically used in conjunction with -extend because user-written  validators
              depend on the type definitions.

       -extend MODULE
              Assume  that  all  type  definitions  are  provided  by the specified module unless
              otherwise annotated. Type aliases are created for each type, e.g. type t = Module.t

       -open MODULE1,MODULE2,...
              List of modules to open (comma-separated or space-separated)

       -nfd   Do not dump OCaml function definitions

       -ntd   Do not dump OCaml type definitions

       -pos-fname FILENAME
              Source file name to use for error messages (default: input name)

       -pos-lnum LINENUM
              Source line number of the first line of the input (default: 1)

       -rec   Keep OCaml type definitions mutually recursive

       -version
              print version and exit

       -help | --help
              Display this list of options
