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 DEFINISIONS 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 consists 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 to 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.
