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
       possible. 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.
