Thought that some people out here might find this useful ... since .dia files are basically just XML files, they can be manipulated using text editing tools. I have always used "replace-string" and "replace-regexp" in Emacs to do some quick editing, but here's a little sed trick that is really worth saving somewhere:
sed -i -e '/\"start_arrow\"/,/attribute/ s/val=\"1\"/val=\"22\"/' diagram.dia I hope that shows up as a single line with only spaces as separators! What it does, is to change the start arrow of every line in diagram.dia from style "1" to style "22". You need to do a bit of experimenting to find out which style is "1" and which is "22". If I am right, "1" used to be the default arrow one upon a time, while "22" is the current default arrow (at least it is in my current Ubuntu setup). I used this script to "upgrade" all my old diagrams to the current arrow style, which looks better. For more information on what that script means, read the following link. In short, this script changes the value assigned to every "dia:attribute" tag with name "start_arrow". http://www.grymoire.com/Unix/Sed.html#uh-29 Here's another example that changes the text size for all objects size "1.2", whatever may be the original size. sed -i -e '/\"height\"/,/attribute/ s/val=\".*\"/val=\"1.2\"/' diagrams.dia Note: 1) Use this at your own risk. 2) This works only if you save dia files in an uncompressed format. There's probably a very simple trick for making it work with compressed files, but I havn't tried. Heck, it might even just work, but like I said, I havn't tried. -- Research Scholar, Department of CSE, IIT Bombay http://www.it.iitb.ac.in/~sameerds/ _______________________________________________ dia-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/dia-list FAQ at http://live.gnome.org/Dia/Faq Main page at http://live.gnome.org/Dia
