Possibly libgsf and neon would obviate any need for gnome-vfs but I haven't really looked in enough depth to say for sure. I haven't confirmed that gnome-vfs actually supports WebDAV, and if it does, how good the support is. WebDAV is composed of a number of different methods, some basic (GET, PUT, HEAD), others more advanced (MOVE, MKCOL, PROPFIND, etc.) So when a lib or app says it supports WebDAV you have to check 'how much'. Neon supports a wide range of them, according to its feature list. http://www.webdav.org/neon/ > As a side note, I've grown a bit bored with working on LibRSVG. I'll have to > check out Inkscape. We'd love to have you, we've been quite impressed with what you've done with librsvg.

The direction we're heading is to make wrapperization of the app easier, whether that be with Python bindings (via SWIG?), Bonobo, or even a kind of SVG Canvas. Being able to plug inkscape into other things opens lots of very interesting uses of it. That, plus being able to interact with files (or svg streams generally) through network connections... I'm not sure I can imagine all the uses, but it would certainly make things possible that haven't been before. > >Yes I noticed these in the API docs, but I was wondering what the > >motivation for inclusion of them in this was?

real world usability test
by bulia byak 10 Dec '03

10 Dec '03

Today my 5 years old daughter spent about 20 minutes in Inkscape, drawing stars. She enjoyed it a lot. She had no problem understanding the role of the selector button ("click it and then you can move your stars around"), node edit button ("click it and you can do funny things to a star by moving those small dots in it") and the star itself. She also used ctrl-z often. The main reason for joy is that the program did not crash :) There were some problems; the biggest bummer was when she accidentally grabbed the handle of the main toolbar and detached it - then she clicked on the canvas and the toolbar was gone! Bad, bad Inkscape. Also, the lack of a palette was a bit of an inconvenience, although I switched the fill&stroke dialog to HSV and she had no problems dragging the hue slider to get different colors for her stars (with two other sliders set to maximum). Overall, I think the program passed this test :) I don't think it would be that enjoyable with Sodipodi, with its myriad of confusing buttons and sinking windows... _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963

Thanks for the pointer. I tried this but it did not work until I replaced: doc->actionkey = NULL; by doc->actionkey = key; in sp_document_maybe_done(). This fix seems logical to me, but it's not my code so please confirm that it's correct. I've just committed a version that puts subsequent same-direction arrow-key movements into one undo step (in both selector and node edit) so you can test how it works. Previously, maybe_done was only used in the item properties dialog (which is planned for elimination btw). _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963

>Realistically, are users ever going to backtrack through more than ~300 >levels of undo anyway? Easy :) Real drawing sessions may span hours and hours. Right now, however, a crash is a more likely outcome of being in Inkscape for too long, but in the future... My opinion is that a vector app must have unlimited undo, or at least very large. It's the promise of the vector: everything is preserved, no loss of information. Unlimited undo is part of that appeal. One thing: right now subsequent arrow-key movements are stored as separate undo steps. I'd like to combine all adjacent moves in one direction (only horizontal or only vertical) in one step. Is there already a mechanism for that, or do I have to dig into the undo system to implement it? _________________________________________________________________ STOP MORE SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=dept/bcomm&pgmarket=en-ca&RU=http%3a%2f%2fjoin.ms…

Counting Lines
by Ted Gould 10 Dec '03

10 Dec '03

Hey, Bryce asked for this, but I thought it might be useful for other people too. There is a little utility on this page called 'lc' which counts lines. There are others too, but I've only used lc. Just so everyone doesn't have to do it, I ran it on the Inkscape codebase and threw it into the attached Gnumeric file ;) http://www.chris-lott.org/resources/cmetrics/ --Ted

Inkscape 0.36 pre-release 1
by Bryce Harrington 09 Dec '03

09 Dec '03

A pre-release version of Inkscape is available for review and testing in source and RPM forms here: http://sourceforge.net/project/showfiles.php?group_id=93438 Please download, test out, and report any significant problems you encounter to the Inkscape bug tracker. We anticipate releasing 0.36 soon, unless any show-stopper bugs (such as frequent crashes) are discovered. Thanks, Bryce

Re: Map Symbols [was Re: [Sodipodi-list] Getting lines straight]

Maybe a novel idea would be to make separate project on sourceforge that is svg clipart. Like svg-clipart.sf.net would be great. The benefits would be open source designing of symbols, maps, etc for the SVG-compliant community. It might also be nice to push the artwork developed via different SVG apps to a standard, well defined place that might promote interoperability and compliance of all,or many :) ofthe different SVG drawing programs. It would be totally cool to use CVS to design with and allow ppl. from all over the world to work on designs. Thoughts? (I hope I haven't just gotten a little too utopian) Jon On Fri, 2003-12-05 at 07:03, Pat Suwalski wrote: > Áki G.

max undo
by bulia byak 09 Dec '03

09 Dec '03

I have increased max undo from 128 to 512, as 128 was way too low imho. In the next version it will be in preferences, but 512 may be the default. Any objections? And by the way, has anyone tried my 256x max zoom patch? _________________________________________________________________ The new MSN 8: advanced junk mail protection and 2 months FREE* http://join.msn.com/?page=dept/bcomm&pgmarket=en-ca&RU=http%3a%2f%2fjoin.ms…

text tool news
by bulia byak 09 Dec '03

09 Dec '03

* src/sp-text.c: fixed typing non-ascii chars; copied (with fixes) treatment of xml:space from sodipodi 0.33 * src/sp-text.h: small fix from sodipodi 0.33 * src/text-context.c: copied sp_text_context_preedit_reset and related code from sodipodi 0.33; xml:space='preserve' is added to newly created text objects; esc deselects; uncatched keys are passed on; misc fixes Please test the text tool thoroughly! What I did NOT copy from sodipodi is the new code within #ifdef SP_TEXT_NEW_CONTENT (no idea what it is, it's off by default) and the pervasive change by which SPObject now has "children" but SPText has not, so all text->children were replaced by much uglier ((SPObject *) text)->children. _________________________________________________________________ Tired of spam?

xml:space default?
by bulia byak 09 Dec '03

09 Dec '03

As a result of my and mental's copying code from sodipodi, now it's possible to set xml:space=preserve via xml editor on a tspan, and the multiple adjacent spaces will not be combined into one as they are now. Does anyone else think it might be a good idea to add this attribute by default to all newly created text objects? BTW this would fix this bug: https://sourceforge.net/tracker/index.php?func=detail&aid=851005&group_id=9… _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.
