MARK EVERITT  I second this. Come on dev!

MACUPDATE ADMIN  See previous versions here:

SHILL  For some reason there was a big whitespace between the top of the page and the previous versions, and I didn't scroll down. D'oh!

Thank you!

SCIFI  To MacUpdateAdminGuys&Gals and to these Developers,

You–all seem to be missing the point. We Tiger users need a *current* version of these apps, not a moldy *previous* version. ;)

I guess I’ll try building from the source tarballs but note it isn’t for the faint–of–heart (that’s what MacPorts users will end–up doing as well). Also note this project in particular looks like it’ll require X11 and all sorts of other non–Mac GUI stuff e.g. GNome, most of which I have already installed locally here as shared libs — thus my build probably won’t be a self–contained one with static libs and I wouldn’t be able to distribute my build for others to use this way — but that’s the way Things Ought To Be™ on a true–blue *ix system for a whole gaggle of technical reasons, most importantly the moldy pre-packaged previous versions will undoubtedly be using old code from the same dependent projects as well.

Y’see how Leopard–only developers are ABUSING the open–source traditions here? Do y’all see that???

Yes indeed even Apple have gotten off–track in this regard also — their “promise” of being “more Linux–friendly” is long–long–long gone IMO.

This website is going to need a new filter that lists only the apps that are known to be Jaguar–, Panther–, Tiger–compatible vis–à–vis Leopard–only etc. etc. etc. etc. etc. And appropriate options be placed on the Developers “Add A File” panel as Required items before posting the app made publicly available.

…ok I had my spiel, bring on the flamewars…

JOHANNES REXX  "Microsoft Word?" What's that? Oh! So why are you using expensive, closed source, proprietary, insecure, license-restricted software when Open Office exists?

I know I know - way of topic - the Devil made me do it ;-)

GLEN LOW  Thanks for looking.

There's not much I can do since .dot is the original UNIX file name extension for Graphviz documents (been in existence for some years now).

In Mac OS 9 or on a HFS system, you could tag such files with creator = MS Word or creator = Graphviz and the system would sort it out. In Mac OS X, you can't be guaranteed this behavior especially if you don't use HFS for your file system, and creating it directly in another text editor would tag the wrong creator anyway.

I'll investigate further, perhaps the creator tag can be fixed when you create a New document.  
(Version 1.13 (v14))

GLEN LOW  v15 should fix this issue, especially on HFS volumes. Now dot files are created with a text file type and Graphviz creator, which should properly associate with Graphviz rather than MS Word.  
(Version 1.13 (v15))

GLEN LOW  Thanks for looking at Graphviz. After you create a new graph using the New menu command, click on the Edit toolbar item and choose a text editor e.g. TextEdit. You can then modify the DOT commands using the editor, and saving it will automatically re-render the graph.

The DOT language is fairly straightforward and there is some online help available.  
(Version 1.13 (v14))

JOHANNES REXX  Let me confess to some laziness. I went ahead and looked at a sample DOT file and then made my own DOT file using the powerful vi command. No problem!

Here is what is TOTALLY COOL about Graphviz. Say I have it open and display my DOT file, then I go into vi and make some edits. Each time I save a change to the file, Graphviz automatically updates its graph. It knows when the file changed! This is insanely great!

Thanks to the developers for their quick and courteous support here on MacUpdate!
