output_filename
This command takes as input
a graph contained in
input_filename and generates as output a graph in
output_filename. This command is mostly used to perform format conversion,
in the case where
input_filename and
output_filename are not encoded in
the same graph formats.
The following ``input formats'' are currently implemented
and available for input_filename:
| - BCG | Binary Coded Graphs format |
| - AUT | ALDEBARAN
graph format |
| - FC2 | ESPRIT project CONCUR2 format (INRIA, Sophia) |
| - SEQ | CADP common
trace format |
The following ``output formats'' are currently implemented and
available for output_filename:
| - BCG | Binary Coded Graphs format |
| - ASCII | ASCII
dump of the BCG format |
| - AUT | ALDEBARAN graph format |
| - AUTO | AUTO and MEIJE graph
format (INRIA, Sophia) |
| - CWB | Concurrency Workbench (LFCS, Edinburgh) |
| - ETMCC | Erlangen-Twente
Markov Chain Checker |
| - FC2 | ESPRIT project CONCUR2 format (INRIA, Sophia) |
| -
GML | Graph Modelling Language (Univ. Passau) |
| - GRAPHVIZ | DOT format of the GRAPHVIZ
tools (ATT) |
| - LOTOS | pseudo-LOTOS format |
| - MEC | MEC graph format (LaBRI, Bordeaux) |
| -
PIPN | PIPN graph format (LAAS, Toulouse) |
| - SCAN | SCAN format (BULL) |
| - SEQ | CADP common
trace format |
| - SQUIGGLES | SQUIGGLES graph format (CNUCE, Pisa) |
| - VCG | Vizualization
of Compiler Graphs (Univ. Saarlandes) |
| - VISCOPE | VISCOPE graph format (IRISA,
Rennes) |
| - XESAR | XESAR graph format (LGI-IMAG, Grenoble) |
Conversions are allowed
from any input format into any output format.
When converting from the BCG
format into a non-BCG output format, the dynamic library corresponding to
input_filename may be generated if necessary.
When converting a non-BCG input
format into a non-BCG output format, a BCG graph and its dynamic library
may be generated as intermediate forms. This is normally transparent to
the end-user.
Conversion from an input format to itself are allowed, but
are useless except in the case of the BCG format: compression parameters
(see below) can be modified this way.
Two groups of general
options,
bcg_options_1 and
bcg_options_2, are currently supported.
Options
bcg_options_1 can appear at the beginning of the command line. These options
are: -version, -create, -update, -remove, -cc, -tmp.
Options bcg_options_2 can
appear on the command line after input_filename. These options are: -uncompress,
-compress, -register, -short, -medium, and -size.
See the bcg
manual
page for a description of these options.
bcg_io is very
flexible with respect to options and file suffixes (i.e., file extensions).
Options or file suffixes can be omitted, provided that there is no ambiguity.
bcg_io does its best to guess the user's intentions and automatically supplies
the missing options and suffixes.
An option can be omitted iff the file
suffix is present and, reciprocally, a file suffix can be omitted iff
the option is present.
If input_file is equal to ``-'', then it is considered
to be the standard input. In such case, the option must be present.
If output_file
is equal to ``-'', then it is considered to be the standard output. In such case,
the option must be present.
Note: if the output option ``-'' is given for producing
the BCG, FC2, or XESAR formats, the standard output of the bcg_io should
be a regular file (not a pipe), because these formats require either that
an explicit output file name is given (XESAR), or that the file can be
accessed randomly using the lseek(2) system call (BCG and FC2).
For example,
the conversion of an AUT file into a FC2 file is normally done as follows:
bcg_io -aldebaran input_file.aut -fc2 output_file.fc2
but equivalent synopses
are allowed, such as:
bcg_io -aldebaran input_file -fc2 output_file
or:
bcg_io input_file.aut output_file.fc2
or (assuming that output_file.fc2 is
a regular file):
bcg_io -aldebaran - -fc2 - <input_file.aut >output_file.fc2
If
output_file is omitted and has only its suffix mentioned, it is assumed
to be equal to inputfile. For example:
bcg_io filename.aut .fc2
is equivalent
to:
bcg_io filename.aut filename.fc2
If the input and output files are
both in BCG format, e.g.:
bcg_io input_file.bcg output_file.bcg
then the
input file, if encoded using an old version of the BCG format, is systematically
converted to the latest version of the BCG format and stored in the output
file.
Finally, uncompressing or compressing a BCG file can be done as follows:
bcg_io input_file.bcg -uncompress output_file.bcg
or
bcg_io input_file.bcg
-compress -size 2 2 4 output_file.bcg
The following associations of options
and filenames are currently available, for input and/or output:
- -bcg input_filename[.bcg]
- Read input_filename.bcg encoded in the BCG graph format.
- -bcg [-parse | -unparse] output_filename[.bcg]
- Write output_filename.bcg encoded in the BCG graph format. General options
-uncompress, -compress, -register, -short, -medium, and -size can be used to
control the contents of output_filename.bcg. Options -parse and -unparse can
be used to control label parsing in output_filename.bcg (see the bcg_write
manual page for a technical discussion about label parsing). By default,
or if option -parse is present, label parsing is enabled. If option -unparse
is present, label parsing is disabled. If the input file is also in BCG
format, options -parse and -unparse will have no effect, as the status of
label parsing used in the input BCG file will be preserved in output_filename.bcg.
- -ascii [-small] output_filename[.ascii]
- Write output_filename.ascii encoded
in the ASCII dump format. If option -small is present, do not display the
contents of the state area, the edge area, and the class area. By default,
these areas are displayed.
- -auto output_filename[.m0]
- Write output_filename.m0
encoded in the AUTO graph format.
- -aldebaran input_filename[.aut]
- Read input_filename.aut
encoded in the AUT graph format (see the aut
manual page for a description
of this format).
- -aldebaran output_filename[.aut]
- Write output_filename.aut
encoded in the AUT graph format.
- -cwb output_filename[.cwb]
- Write output_filename.cwb
encoded in the CWB graph format.
- -etmcc [-format format_string] output_filename[.tra]
- Write output_filename.tra encoded in the ETMCC graph format. If option -format
format_string is present, it specifies the form under which floating-point
numbers are printed to the output file See the bcg_min
and determinator
manual pages for a detailed description of format_string. By default, i.e.,
if option -format is absent, the default value of format_string is
"%g".
- -fc2 [-net number] input_filename[.fc2]
- Read input_filename.fc2 encoded in
the FC2 graph format. If option -net number is present, select the number-th
automaton contained in input_filename.fc2. If option -net is not specified,
number is given the default 0.
- -fc2 [-verbose] output_filename[.fc2]
- Write
output_filename.fc2 encoded in the FC2 graph format. If option -verbose is
present, use the verbose form of FC2 (by default, the compact form of
FC2 is used).
- -gml output_filename[.gml]
- Write output_filename.gml encoded in
the GML graph format.
- -graphviz output_filename[.dot]
- Write output_filename.dot
encoded in the DOT graph format of the GRAPHVIZ tools.
- -lotos output_filename[.lotos]
- Write output_filename.lotos in pseudo-LOTOS format.
- -mec output_filename[.mec]
- Write output_filename.mec encoded in the MEC graph format.
- -pipn output_filename[.auto.pro]
- Write output_filename.auto.pro encoded in the PIPN graph format.
- -scan output_filename[.scan]
- Write output_filename.scan encoded in the SCAN graph format.
- -sequence input_filename[.seq]
- Read input_filename.seq encoded in the simple SEQ format (see the seq
manual page for a description of this format).
- -sequence output_filename[.seq]
- Write output_filename.seq encoded in the simple SEQ format. Translating a
graph to the SEQ format is only possible if the graph has no circuits and
if all its states (with the possible exception of the initial state) have
at most one outgoing edge.
- -squiggles output_filename[.graph]
- Write output_filename.graph
encoded in the SQUIGGLES graph format.
- -vcg output_filename[.vcg]
- Write output_filename.vcg
encoded in the VCG graph format.
- -viscope output_filename[.trans]
- Write output_filename.trans
encoded in the VISCOPE graph format.
- -xesar [-old] output_filename[.gra]
- Write
output_filename.gra encoded in the XESAR graph format. Three auxiliary files
(output_filename.dp3, output_filename.ge3, and output_filename.tai) are
also generated. If option -old is present, use the old XESAR format (this
format is now obsolete and does not work for graphs with more than 65536
states). By default, the new XESAR format is used.
The letters ``io'' in
bcg_io stand for input/output.

bcg
manual
page for a description of the environment variables used by all the BCG
application tools.
Exit status is 0 if everything is alright,
1 otherwise.
