GXL2GV,GV2GXL(1)					      General Commands Manual						  GXL2GV,GV2GXL(1)

NAME

       gxl2gv,gv2gxl - GXL-GV converters

SYNOPSIS

       gxl2gv [ -gd?  ] [ -ooutfile ] [ files ]
       gv2gxl [ -gd?  ] [ -ooutfile ] [ files ]

DESCRIPTION

       gxl2gv  converts  between graphs represented in GXL and in the GV language. Unless a conversion type is specified using a flag, gxl2gv will
       deduce the type of conversion from the suffix of the input file, a ".gv" suffix causing a conversion from GV to GXL, and  a  ".gxl"  suffix
       causing	a  conversion  from  GXL  to GV.  If no suffix is available, e.g. when the input is from a pipe, and no flags are used then gxl2gv
       assumes the type of the input file from its executable name so that gxl2gv converts from GXL to GV, and gv2gxl converts from GV to GXL.

       GXL supports a much richer graph model than GV. gxl2gv will attempt to map GXL constructs into the analogous GV construct when this is pos-
       sible.  If  not,  the GXL information is stored as an attribute. The intention is that applying gxl2gv|gv2gxl is semantically equivalent to
       the identity operator.

OPTIONS

       The following options are supported:

       -g     The command name and input file extensions are ignored, the input is taken as a GV file and a GXL file is generated.

       -d     The command name and input file extensions are ignored, the input is taken as a GXL file and a GV file is generated.

       -?     Prints usage information and exits.

       -o outfile
	      If specified, the output will be written into the file outfile. Otherwise, output is written to standard out.

OPERANDS

       The following operand is supported:

       files   Names of files containing 1 or more graphs in GXL or GV.  If no files operand is specified, the standard input will be used.

RETURN CODES

       Both gxl2gv and gv2gxl return 0 if there were no problems during conversion; and non-zero if any error occurred.

BUGS

       gxl2gv will only convert in one direction even if given multiple files with varying suffixes.

       The conversion can only handle one graph per GXL file.

       There are some GXL constructs which gxl2gv cannot handle.

GML2GV,GV2GML(1)					      General Commands Manual						  GML2GV,GV2GML(1)

NAME

       gml2gv,gv2gml - GML-DOT converters

SYNOPSIS

       gml2gv [ -?v ] [ -ggname ] [ -ooutfile ] [ files ]
       gv2gml [ -?  ] [ -ooutfile ] [ files ]

DESCRIPTION

       gml2gv  converts  a graph specified in the GML format to a graph in the GV (formerly DOT) format.  gv2gml converts a graph specified in the
       GV format to a graph in the GML format.

OPTIONS

       The following options are supported:

       -v     Turns on verbose mode

       -?     Prints usage information and exits.

       -ggname
	      The string gname is used as the name of the generated graph.  If multiple graphs are generated, subsequent graphs use the name gname
	      appended with an integer.

       -ooutfile
	      Prints output to the file outfile. If not given, gml2gv uses stdout.

       OPERANDS
	      The following operand is supported:

       files   Names of files containing 1 or more graphs in GML.  If no files operand is specified, the standard input will be used.

RETURN CODES

       Return 0 if there were no problems during conversion; and non-zero if any error occurred.

LIMITATIONS

       As  both  the graph and graphics models of GV and GML differ significantly, the conversion is at best approximate. In particular, it is not
       clear how multiedges are differentiated in GML, so multiedges are created in GV with no user-available key. Also, no attribute  information
       is lost, in that any GML attributes that aren't converted to GV equivalents are retained as attributes in the output graph.

       At  present,  gv2gml  does not support subgraphs and clusters. In addition, there does not appear to be a standard mechanism for specifying
       default node and edge attributes in GML, so any attributes are repeated for every node and edge.
