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" (or a ".dot") 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.
