Bug #23942 for Graph-Easy: Incorrect graphviz output

Subject:	Incorrect graphviz output

Hi, The attached graph file is incorrectly translated to graphviz format, when using the command $output = Graph::Easy::Parser->from_file($graph_file)->as_graphviz(); In particular, the target of the edge from [3046] -> [3085] should be 3085, but 3084 is drawn in its place. This uses Graph::Easy 0.49. Perl and Linux version are: This is perl, v5.8.8 built for i486-linux-gnu-thread-multi Linux lindt 2.6.17-10-generic #2 SMP Fri Oct 13 18:45:35 UTC 2006 i686 GNU/Linux Thanks Paul PS Additionally, I couldn't install Graph::Easy::As_svg from CPAN. Perhaps this is related to the missing .meta file? -- Paul Biggar paul.biggar@gmail.com

I will have a look at the bug. Regarding As_svg, it is borked due to a bug in 0.49. I have 0.50 and a new version of As_svg "almost" ready, but got bogged down with reallife (new camera, xmas travel and preparations). I will release these versions around christmas - have a lot of free time then :) You can get the devel versions here: http://bloodgate.com/perl/packages/devel/ Thanx a lot for the report! best wishes, tels - -- Signed on Thu Dec 14 22:35:24 2006 with key 0x93B84C15.

Hi tels, Thanks for getting back to me so quick. As is the way with these things, I found the bug just after I reported it. the bug is actually due to the presence of the # character in the label field. When I convert them all to X, it translates into .dot properly. Thanks Paul On 12/14/06, nospam-abuse@bloodgate.com via RT <bug-Graph-Easy@rt.cpan.org> wrote:

I was suspecting something along these lines. The "#" is the comment character, so it probably confuses the parser. Have you tried quoting the label? Anyway, I found a few bugs in the as_graphviz() output, like it outputs things like "rows=" and "groups=" which it shouldn't! So thanx again! I'll send you an email when I finally release v0.50. Hopefully manage it this weekend :) Best wishes, Tels - -- Signed on Thu Dec 14 23:17:10 2006 with key 0x93B84C15.

I just released v0.50 of Graph::Easy, along with a new version of As_svg and the manual. In the manual, I added some text about "#" to the Syntax chapter, explaining that you need to escape the "#" along with ";" in attribute values, or the parser sees them as start of a comment, respectively as end of the attribute value. So I am closing this bug report now as resolved. If you have any more issues, please do not hesitate to report them! Best wishes, Tels
