call of 'virtualenv' with option 'p=python3' syntactically wrong
by fi＠igh.de 04 Jun '24

Dear Maintainers, after pulling revision 5448704355e03a97d2838e1ba30272db335f0dbb I have built inkscape according to https://inkscape.org/develop/getting-started/ Trying to manage extensions (Extensions -> Manage Extensions) I receive the following error message: There has been a problem creating the python environment: Return Code: 3: b'' b'The path =python3 (from --python==python3) does not exist\n' args: ['/usr/bin/virtualenv', '-p=python3', '/home/xx/.config/inkscape/extensions'] Indeed the call is syntactically wrong. Instead of '-p=python3' the option '-p python3' ### without equal sign should be used. As far as I understand, the problem seems to exist in inkscape/share/extensions/extension-manager-bootstrap.py:69 call('virtualenv', TARGET_DIR, p='python3') which then in inkex/command.py:to_args() is evaluated to the wrong sytnax. According to the (very good) comments in to_args() :Keyword Arguments: * *name* (``str``) -- Becomes ``--name="val"`` ... * *n* (``str``) -- Becomes ``-n=val`` ... it should become ``-n val``. I do not know whether a change would result in problems using other programs that want -n=val. Which should that be?

win32 build working again
by Bob Jamison 08 Apr '24

The win32 build, which was broken for the weekend, is working again. I just made a "manual autobuild" again, so that we can see how it looks on Windows: http://troi.titan-aeu.com/~rjamison/inkscape/builds/ Bob

Regarding the serialization of Spiro control points
by Fred Brennan 28 Mar '22

28 Mar '22

Greetings, I write from the FontForge project. Of particular interest to me is the Spiro spline feature, which was originated around ten years ago by Raph Levien. One thing I'd like to add, (which would benefit both our projects,) is the ability of FontForge to understand the Inkscape Spiro serialization format. However, there are several things about the format which to me as an outsider appear to be defects serious enough that I have no idea how to even *import* these splines correctly, much less export our Spiro splines to this format. I would very much like to support the _de facto_ standard Inkscape has originated of supporting Spiro in SVG, but I am lost. George Williams, FontForge's original author, noticed this defect over eleven years ago.[1] Things are virtually unchanged since then, I checked `git blame`. Spiro has five point types, not including beginning and ending points. They are: * G4 curve (o) * G2 curve (c) * Corner (v) * Left Constraint ([) * Right Constraint (]) The ASCII single letters are the normal method of Spiro serialization, as championed by Raph Levien and by us in FontForge. Inkscape seems to create what I will call a "pseudo-SVG path". So, it is not really an SVG path, but rather is an SVG path which undergoes transformation into the typical Spiro format. Inkscape stores this in the "original-d" attribute. So, given a Bezier spline with control points defined as (x, y, c1, c2), Inkscape interprets a control point with only (x, y) to be a corner, meanwhile a control point with all four is a G4 curve, and (x, y, c1, NULL) is a left constraint while (x, y, NULL, c2) is a right constraint. I can probably overcome this, although George Williams was right to be skeptical of this format. There is no way I can see to define a G2 curve in this strange "original-d" format. Thus, this email. I write to ask a few things. I suppose first of all, what are the chances that we can convince you guys to store Spiro splines in plate[2] format, or another widely accepted Spiro serialization format? Second, if we cannot convince you to do that, how do I export FontForge spiros which contain G2 control points to Inkscape's original-d format? It's not possible, yes? So should I just silently fail and save them as G4? The curves will not be the same if I do that. Should I disallow export to SVG w/Spiro if glyph contains G2 control point? That seems a steep cost that will just confuse my users, so perhaps I should abandon the whole thing if it comes to that. Cordial regards, Fredrick Brennan (@ctrlcctrlv) [1]: https://narkive.com/63FADpG3.4 [2]: https://levien.com/garden/ppedit/README, section "Plate files"

Help us staff a booth at the largest German Online Linux event (English/German)!
by Maren Hachmann 27 Dec '21

27 Dec '21

Hi everyone, the Inkscape project is planning to host a virtual booth/stand again at the Chemnitzer Linuxtage (CLT), on March 12 and 13 (Sat/Sun) 2022! Usually the largest Linux and Open Source event in Germany, CLT are going to be an online-only event in 2022 again. The CLT (Chemnitzer Linuxtage) are an all-day event and we could use your help answering user questions about how to work with the program, how to contribute to it and about what is going on in the Inkscape community, by being available for questions and chatting at our virtual booth. The other thing we plan to do again is a series of short, 10 to 50 min topic-focused sessions – show other users how you use Inkscape, how to use your Inkscape extension, how people can help the Inkscape project or which cool things you made with Inkscape (and they can, too!). A live drawing session, a demonstration, a tour through your maker lab - anything that has to do with Inkscape is possible! So, no matter if you're 'just a user', a developer, a forum member, a regular user support provider in our chat channels, an Inkscape translator or other contributor – if you have some time available to spend helping the Inkscape project on that weekend in March, we would very much appreciate your help! Start by introducing yourself at the GitLab issue report where we're discussing the event organization! ****************** Please get in contact with us as soon as possible and find more info at https://gitlab.com/inkscape/vectors/general/-/issues/235 Let us know how you can help make the booth an interesting place for visitors to drop by! ****************** We're going to have a first chat meeting with all those interested on Saturday, January 8, 2022 at 17:30 UTC (18:30 German time, after the Inkscape Vectors' meeting) at https://chat.inkscape.org/channel/team_vectors Hope to see you, it's going to be fun! If you are not able to join us at the booth, consider visiting us there! Kind Regards Maren ------------------ More info: Chemnitzer Linuxtage: https://chemnitzer.linux-tage.de/2022/en/ What we did last year: https://gitlab.com/inkscape/vectors/general/-/issues/192

Inkscape PLC Meeting (moved to Nov 12, 2021)
by Ted Gould 03 Dec '21

03 Dec '21

Howdy folks, I am late getting out this notice and folks in the chat mentioned it'd be easier for everyone if we shifted the normal meeting back a week. So we're planning on having it Nov 12, 2021 and high noon Texas time. I think this gets is out of the confusing week where everyone is on different daylight savings time as well. Timezone tool: https://www.timeanddate.com/worldclock/fixedtime.html?iso=20211112T10&p1=202 Wiki page: https://wiki.inkscape.org/wiki/Leadership_Committee_Status_Updates I'll note that we have a few votes outstanding and if all board members could look and make sure you voted that would be helpful. I hope to do an audit on those tonight or tomorrow and it's a lot easier if all the votes are in! Otherwise you'll be shamed at the meeting 😉 Ted
