Bug[edit] cheers --FischX (talk) 11:44, 22 February 2015 (UTC)

Works fine for me. What's the bug? --Atlasowa (talk) 09:07, 23 February 2015 (UTC)
Now I get the bug too :(
"javax.servlet.ServletException: vcat.VCatException: !QueuedVCatRenderer.Exception.Graphviz!"
Bummer because i just wanted to show off VCat at en:Wikipedia:Village_pump (idea_lab)#Show branching tree of articles and sub-articles in graphic form. --Atlasowa (talk) 09:01, 27 February 2015 (UTC)
Same with redirect link. --Atlasowa (talk) 09:05, 27 February 2015 (UTC)
Czech Wikipedia Natural Sciences category tree
That is cool! Have the color clouds been added afterwards or did i miss out on features? :-) --Atlasowa (talk) 09:08, 27 February 2015 (UTC)

I had fixed the problem (caused by a server outage) on 22 February, that is why it was OK the day after. Unfortunately Tool Labs had another server outage, and this broke vCat again, sometime on 25 February. It was easy to fix by restarting everything, but I really need a way to do this automatically. --dapete 16:30, 27 February 2015 (UTC)

  • I get the error again: javax.servlet.ServletException: vcat.VCatException: !QueuedVCatRenderer.Exception.Graphviz!
BTW: How far is your monitoring and restarting project?

Zwischending zwischen Anzeige der Ober- und Unterkategorien[edit]

Gibt es ein tool, das mir anzeigt, auf welchem Weg ein Artikel (oder eine Kategorie) in irgendeine Unterkategorie einer bestimmten Kategorie gerät? Konkret: Wieso steht de:Albert von Pfister irgendwie unter de:Kategorie:Auszeichnung? Irgendwo muss ein systematischer Fehler im Kategorie-System stecken, den ich nicht finde. Viele Grüße, --Drahreg01 (talk) 14:52, 19 May 2016 (UTC)

So explizit soweit ich weiß nicht - aber ich hab im Baum für Albert von Pfister die Stelle gefunden: mittig über dem "Albert von Pfister", fast ganz oben, sieht man de:Kategorie:Auszeichnung mit einem Pfeil zu de:Kategorie:Nobilitierter (Baum dazu). --dapete 15:44, 19 May 2016 (UTC)
Vielen Dank! --Drahreg01 (talk) 03:27, 20 May 2016 (UTC)

Thanks, two questions, and a suggestion for the instructions[edit]

Fantastic tool, thanks for putting it together! It really makes cleaning up categories easier. Two questions - is there any plan to eventually add color (I'm thinking mostly of one color for direct categories of an article, and then a second color for categories that are both direct categories and parents of an applied category), or to put together a requestor form?

Also I thought it would be helpful for the instructions page to have an example of a more complex request with a multiword 'title' value -Furicorn (talk) 18:42, 27 August 2017 (UTC)

Question about multiple categories as roots[edit]

Am I misreading the instructions for generating an image from multiple roots? -Furicorn (talk) 03:36, 29 August 2017 (UTC)


@Dapete, returns only a 1 depth diagram. Is this a bug? Or do not I understand what depth parameter is? Thanks --Joan301009 (talk) 12:46, 22 November 2017 (UTC)

@Joan301009 There is a limit of 250 categories in one diagram, because otherwise the files become too large. The depth is automatically reduced to come below the limit. If you want it all, you have to use "&format=gv" to output the raw Graphviz source, and convert it to an image yourself. --dapete 13:15, 28 November 2017 (UTC)
Thanks! --Joan301009 (talk) 19:07, 29 November 2017 (UTC)

vcat/render[edit] gives the following error:

 error on line 15 at column 72: EntityRef: expecting ';'

Übersetzung ins Italienische[edit]

Hallo @Dapete:, kann ich in diese Seite eine Übersetzung ins Italienische hinzufügen? --Lombres (talk) 17:46, 28 January 2019 (UTC)
