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.
-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.
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.
