NAME

       yaz-asncomp - YAZ ASN.1 compiler

SYNOPSIS

       yaz-asncomp [-v] [-c cfile] [-h hfile] [-p pfile] [-d config] [-I includeout]
                   [-i includedir] [-m module] [filename]

DESCRIPTION

       yaz-asncomp is an ASN.1 compiler that reads an ASN.1 specification in filename and
       produces C/C++ definitions and BER encoders/decoders for it.

       The produced C/C++ code and header files uses the ODR module of YAZ which is a library
       that encodes/decodes/prints BER packages.  yaz-asncomp allows you to specify name of
       resulting source via options. Alternatively, you can specify a DEFINITIONS file, which
       provides customized output to many output files - if the ASN.1 specification file consists
       of many modules.

       This utility is written in Tcl. Any version of Tcl should work.

OPTIONS

       -v
           Makes the ASN.1 compiler print more verbose about the various stages of operations.

       -c cfile
           Specifies the name of the C/C++ file with encoders/decoders.

       -h hfile
           Specifies the name of header file with definitions.

       -p pfile
           Specifies the name of the a private header file with definitions. By default all
           definitions are put in header file (option -h).

       -d dfile
           Specifies the name of a definitions file.

       -I iout
           Specifies first part of directory in which header files are written.

       -i idir
           Specifies second part of directory in which header files are written.

       -m module
           Specifies that ASN.1 compiler should only process the module given. If this option is
           not specified, all modules in the ASN.1 file are processed.

DEFINITIONS FILE

       The definitions file is really a Tcl script but follows traditional rules for Shell like
       configuration files. That is # denotes the beginning of a comment. Definitions are line
       oriented. The definitions files usually consist of a series of variable assignments of the
       form:

       set name value

       Available variables are:

       default-prefix
           Sets prefix for names in the produced output. The value consists of three tokens: C
           function prefix, C typedef prefix and preprocessor prefix respectively.

       prefix(module)
           This value sets prefix values for module module. The value has same form as
           default-prefix.

       filename(module)
           Specifies filename for C/header file for module module.

       init(module,h)
           Code fragment to be put in first part of public header for module module.

       body(module,h)
           Code fragment to be put in last part of public header for module module (trailer).

       init(module,c)
           Code fragment to be put in first part of C based encoder/decoder for module module.

       body(module,c)
           Code fragment to be put in last part of C based encoder/decoder for module module
           (trailer).

       map(module,name)
           Maps ASN.1 type in module module of name to value.

       membermap(module,name,member)
           Maps member member in SEQUENCE/CHOICE of name in module module to value. The value
           consists of one or two tokens. First token is name of C preprocessor part. Second
           token is resulting C member name. If second token is omitted the value (one token) is
           both preprocessor part and C struct,union.

       unionmap(module,name,member)
           Maps member member in CHOICE of name in module module to value. Value consists of two
           or three tokens. The first token is name of the integer in the union that is used as
           selector for the union itself. The second token is name of the union. The third token
           overrides the name of the CHOICE member; if omitted the member name is used.
