PROGRAM:

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
