.SH DESCRIPTION
This manual page is a quick reference for the TTCN-3 and ASN.1 to C++ (or JSON schema)
compiler of the TTCN-3 Test Executor. It only summarizes the meaning of
all command line options. For more details please consult the
.B Programmer's Technical Reference for TITAN TTCN-3 Test Executor.
.SH OPTIONS
The following options are supported (in alphabetical order):
.TP 10
.BI \-A " file"
Forces the interpretation of
.I file
as an
.I ASN.1 module.
It is useful when automatic module type detection fails
due to some strange language constructs. The option takes exactly one file
name as argument. The option must be repeated when used with multiple files.
See also: option
.B \-T.
.TP
.B \-a
Force
.I XER
in ASN.1 files
.TP
.B \-b
Disables the generation of
.I BER
encoder/decoder routines for all ASN.1 types.
.TP
.B \-B
Allows the selected field in a union value to be unbound, when setting module
parameters (legacy behavior). A warning is displayed whenever a union value
receives an unbound selected field and when a union with an unbound selected field
is copied.
.TP
.B \-c
Write out
.I checksums
in case of error
.TP
.B \-d
Treat ASN.1
.I SEQUENCE/SET
fields with DEFAULT values as
.I omit
in TTCN-3.
.TP
.B \-D
Disable generation of user and time information comments in the output C++ code.
.TP
.B \-e
Enforce legacy handling of encode and variant attributes.
.TP
.B \-E
Instructs the variant attribute parser to display warnings instead of errors
for unrecognized/erroneous attributes.
.TP
.B \-f
Forces the compiler to
.I overwrite
the output files even if they exist or are unchanged.
.TP
.B \-F
Forces the compiler to generate the full C++ classes for records of/sets of basic types (i.e. boolean, integer, float, bitstring, hexstring, octetstring, charstring and unversal charstring). Otherwise only type aliases to pre-generated classes are generated for these types. This also disables the type compatibility between records of/sets of basic types in the Load Test Runtime.
.TP
.B \-g
The compiler error/warning messages will contain only the starting
line number and column, in a format compatible with th GNU compiler (gcc).
.B \-g
takes precedence over
.B \-i
if both are specified.
.TP
.B \-h
Allows unsafe universal charstring to charstring conversion.
.TP
.B \-i
The compiler error/warning messages
will contain only the
.I line numbers,
the column numbers will remain hidden. This option provides backward
compatibility with the error message format of earlier versions.
.TP
.B \-I
Enables real-time testing features.
.TP
.B \-j
Disables JSON encoder/decoder functions.
.TP
.BI \-J " file"
Read a list of input files from the provided file.
.TP
.B \-k
Enables object-oriented features.
.TP
.BI \-K " file"
Enables selective code coverage.
.TP
.B \-l
Instructs the compiler to generate source file and line information (i.e.
.I #line
directives) into the output C++ code so that the C++ compiler error
messages refer back to the lines of original TTCN-3 input module.
.br
This option is
.I obsolete
and will be removed in future versions as the
compiler does not generate erroneous C++ code because of the full
semantic analysis.
.TP
.B \-L
Instructs the compiler to add source file and line
.I source file
and
.I line number
information into the generated code to be included in the
.I log
during execution.
.br
This option is only a prerequisite for logging the source code information.
Options
.I SourceInfoFormat
and
.I LogEntityName
have also to be set appropriately in section
.I [LOGGING]
of the run-time configuration file.
.br
Usage of this option a bit enlarges the size of the generated code and slightly
reduces execution speed. This flag is not recommended when the TTCN-3 test
suite is used for load generation.
.TP
.B \-M
Allows the use of the value
.B omit
in template lists and complemented template lists (legacy behavior).
If set, an omitted field will match a template list, if the value
.B omit
appears in the list, and it will match a complemented template list, if
.B omit
is not in the list (the
.B ifpresent
attribute can still be used for matching omitted fields). This also affects the
.B ispresent
operation and the
.B present
template restriction accordingly.
.TP
.B \-n
Activates the debugger and generates extra code for storing debug information.
.TP
.B \-N
Ignore UNTAGGED encoding instruction on top level unions (legacy behaviour).
.TP
.BI \-o " dir"
The output files (including Test Port skeletons) will be placed into
the directory specified by
.I dir.
The current working directory is the default otherwise.
.TP
.B \-p
Instructs the compiler only to
.I parse
the given TTCN-3 and ASN.1 modules. This will detect only the syntax errors
because semantic checkings are
.I not
performed. The presence of all imported modules is not necessary thus it is
allowed (and recommended) to parse the modules one-by-one.
.br
All options that influence the code generation are silently ignored when used
together with
.B \-p.
.br
.B Note:
This option includes complete syntax checks for TTCN-3 modules, but in ASN.1
there are some special constructs (e.g. the user-defined syntaxes) that cannot
be even parsed without semantic analysis. So there is no guarantee that an ASN.1
module is free of syntax errors if it was analyzed with compiler using the
.B -p
flag.
.TP
.BI \-P " top_level_pdu" ...
Defines a top-level pdu.
.I top_level_pdu
must have the following format:
.I modulename.identifier.
If this switch is used, then only the defined top-level PDU(s) and the
referenced assignments are checked and included in code generation, the
other ASN.1 assignments are skipped.
.TP
.B \-q
.I Quiet
mode. Equivalent with
.B \-V 0.
.TP
.B \-Qn
.I Quits
after 
.B n
errors.
.TP
.B \-r
Disables the generation of
.I RAW
encoder/decoder routines for all TTCN-3 types.
.TP
.B \-R
Use function test runtime (TITAN_RUNTIME_2). The compiler will generate source
code for use with function test runtime.
.TP
.B \-s
Instructs the compiler to parse the given TTCN-3 and ASN.1 modules and perform
.I semantic analysis
on them, but
.I not
to generate C++ output. The list of given modules shall be complete so it is
not allowed to import from a module that is not in the list. All options that
influence the code generation are silently ignored when used together with
.B \-s.
.TP
.B \-S
.I Suppresses 
context information.
.TP
.B \-t
Generates
.I Test Port
and
.I External Class
skeleton header and source files for all port types and external class types
that can be found in the input TTCN-3 modules. Existing Test Port and External Class
files will not be overwritten unless the
.B \-f
option is used.
.TP
.BI \-T " file"
Forces the interpretation of
.I file
as a
.I TTCN-3 module.
See also: option
.B \-A.
.TP
.B \-u
Forces the compiler to do
.I duplicate underscore
characters in all output file names. This option turns on the
compatibility mode with versions 1.1 or earlier.
.TP
.BI \-U " none|type|'number'"
Selects code splitting mode for the generated C++ code.
The 'number' should be a positive number between 1 and 999999.
If the 'number' is present the files will be sliced into 'number' files.
.TP
.B \-v
Prints
.I version
and license key information and exits.
.TP
.BI \-V " verb_level"
Sets the verbosity bit-mask directly to
.I verb_level
(where
.I verb_level
is a decimal value between 0 and 65535).
.br
.sp 1
Meaning of bits:
.P
.RS 10
.PD 0
.TP 10
.B 1:
"NOT SUPPORTED" messages.
.TP
.B 2:
WARNING messages.
.TP
.B 4:
NOTIFY messages.
.TP
.B 32|16|8:
DEBUG messages.
.br
The debug-bits act like a 3-bits-length number, so the debug level has
a value between 0 and 7. It is useful in case of abnormal program termination.
.PD
.RE
.P
.TP 10
.B \-w
Suppresses all
.I warning
messages. Equivalent with
.B \-V 4.
.TP
.B \-x
Disables the generation of
.I TEXT
encoder/decoder routines for all TTCN-3 types.
.TP
.B \-X
Disable
.I XER
encoder/decoder functions
.TP
.B \-y
Disable
.I subtype
checking
.TP
.B \-Y
Enforces legacy behaviour of the "out" function parameters (see refguide).
.TP
.BI \-z " file"
Enables profiling and code coverage in the selected TTCN-3 files. The
.I file
argument contains a list of TTCN-3 files separated by new lines. Each TTCN-3 file must be among the compiler's TTCN-3 file arguments.
.TP
.B \-0
Disables attribute checks for
.I encvalue
and
.I decvalue.
Must be used together with option
.I \-s.
.TP
.B \-
The single dash character as command line argument controls the
.I selective code generation
option.
After the list of all TTCN-3 and ASN.1 modules a subset of these files can
be given separated by a dash. This option instructs the compiler to parse all
modules, perform the semantic analysis on the entire module hierarchy, but
generate code
.I only
for those modules that are listed after the dash again.
.br
It is not allowed to specify a file name after the dash that was not present
in the list before the dash. If the single dash is not present in the command
line the compiler will generate code for
.I all
modules.
.TP
.B \-\-ttcn2json
Generates a JSON schema from the types defined in the specified TTCN-3 and ASN.1 modules.
Must always be the first compiler option. From the previously listed options only
.B \-T
and
.B \-A
can be used, instead the JSON schema generator has options of its own:
.TP
.B \-j
Only types that have JSON coding enabled are included in the schema.
.TP
.B \-f
The schema only validates types that have a JSON encoding or decoding method declared.
.TP
.BI \- " file"
The single dash character as command line argument specifies the name of the generated
JSON schema file. If it is not present, then the schema file name is generated from
the name of the first input file (by replacing its suffix with
.I \.json
or appending
.I \.json
to the end of the file).
.SH EXIT STATUS
The compiler exits with a status of zero when no errors were encountered
during its operation. A status of one will be returned if syntax or
semantic errors were detected in the input modules.
.SH ENVIRONMENT VARIABLES
.TP
.SM
TTCN3_DIR
The installation directory where the uncompressed binary package of
TTCN-3 Test Executor can be found.
.TP
.SM
TTCN3_LICENSE_FILE
It shall point to the
.I file
.RB ( NB:
.I not
to its directory) that contains the personalized license key for the
current user or host.
.SH BUGS
The compiler does not support all constructs of TTCN-3 Core Language and ASN.1.
It reports an error when encountering an unsupported language element.
The detailed list of deficiencies and language extensions can be found in the
referenced documentation.
