Can you update me on how things are going right now? Are there particular things you're stuck on? I probably don't know enough to offer advice myself but maybe can suggest someone that can. If the issue looks like it can't be solved quickly, perhaps for testing purposes it might help to add one or two environment variables to turn on/off pieces of the UI or codebase that are causing problems. So if someone testing the renderer can do without the toolbar, they can disable it at runtime? Something like that? In the coming weeks I'd like to produce a testing build of Inkscape, so if there are some (ugly) ways to enable testers to work around the performance bug that would help.

Running the build on mac
by Elizabeth Kirby 07 Mar '18

07 Mar '18

Hi all, I'm trying to get inkscape to run on the mac. I downloaded a zip of the code (recently) & installed a handful of packages using ports. There was one dependency that I couldn't get to resolve using any ports package, which is libsoup. I installed it using brew & then the code will compile. It will run, but not correctly. I put in a symlink from /usr/share/inkscape to my build tree share directory & it does load the items on the right & left sides, but without any of the images that tell what they are. I would rather not have a symlink in /usr/share, but instead just have the build read from the build tree. Are there any people developing on mac out there that can share their configuration & settings & tell me what parameters need to be set & where? Thanks, Beth

This is super cool! I specially loved the CSS animation of the weight of the text when the cursor hovers over a button. This seems to replace Tav's opentype features selector via a GTK font-selector dialog. It also seems that we could have the innitial variable fonts support in inkscape basically hooking up to this newly improved GTK dialog. Naturally, that would require Inkscape to rely on a pretty recent version of GTK.

Inkscape PGP signatures and SHA256 checksums?
by Tom Spettigue 06 Mar '18

06 Mar '18

Hey guys. I was wondering if you guys provided PGP signatures of your guys' installer files? If so, I couldn't find the site, it'd be nice to have links to the pgp signatures and pgp signing keys right there on the download page. If you guys don't have this, it'd be a great way for us to verify that the installers that we download are genuine. SHA256 checksums (for users who understand hashing, but not PGP) would be pretty rad, too. -- Tom Spettigue Advent Information Systems, L.L.C. 1607 Capitol Avenue, Suite 220 Cheyenne, WY 82001 Mobile: (307) 298-0299 Email: tom@...3644...

I left this aside for the past 6 months and recently got back to looking at it. I think the most trivial thing would be to populate the font-styles combo-box with named instances. This would be almost not perceptible by the users, but would enable variable fonts' instances to show up there just like their non-variable counterparts do. Then there's the customization aspect of varfonts. For that, I think the bare minimum would be a bunch of sliders for selecting the coordinates of each variation axis. I feel that there must be something better than that form a user experience perspective, but I'm still not sure what would that be, so I'd leave it for a second iteration of the UI. Also, since one can get a multitude of combinations within the designspace, I think it could be practical to adopt a UI workflow similar to that of color gradients, in which once a user-defined instance is applied to a text chunk, that instance is added to a pool of var font instances that can be reused in other chunks of texto within the document. A shared varfont would then, upon tweaking of its design space coordiantes, affect all portions of the document where it was used. Finally, and this is not a varfont specific issue, I feel the urge to improve the basic text support in Inkscape in general. Yes, I know this is a somewhat vague statement. The overall direction I'd like to follow, though, would likely be something similar to the insightful ideas that are expressed in this article: https://medium.com/@getflourish/the-anatomy-of-a-thousand-typefaces-f7b9088… cheers, Felipe Sanches 2018-03-06 11:27 GMT-03:00 Pathum Egodawatta <pathumego@...400...>: > Hi Filipe! > > Hope you are doing well.

A bit unfair to ask Eduard to do this, if the website isn't letting you deploy files easily, then that's a tooling issue we can fix. But I can't fix it if the social protocol is to not ask for help and instead figure out a technical workaround. Regards, Martin, Website guy who can help

There are a few rough edges that we had to work around. In fact, one of them just came up: https://github.com/lexelby/inkstitc h/issues/18#issuecomment-370301197. In that thread, we're talking about creating a PDF printout feature that shows the colors used in a design and the order they sew in. My original plan was to use the nifty, growing list of features in the command-line interface for Inkscape. My understanding is that these features are provided specifically to act as a "standard library" of functionality that can be used by extensions. The problem with this is that extensions don't know where the Inkscape binary is. I can imagine writing code to guess, or perhaps look at the parent process, but trying to support Linux, Windows, and Mac sounds like a nightmare. End result: ink/stitch can't use this functionality. Another rough edge is that extensions don't know where the current SVG file is stored on disk. We can access the file's basename, but not the directory. This is kind of annoying because ink/stitch wants to output a machine embroidery design file (.DST, .PES, etc). ink/stitch works around this by storing all of these files in a set "output directory" specified by the user, but this is obviously not ideal. Here's where one of our users/contributors discusses his desire for the design file to save alongside the SVG: https://github.com/lexelby/inkstitch/issues/ 75 I gather that Inkscape did previously store the directory, but it was removed due to privacy concerns. Perhaps the directory can be included in the SVG _only_ when communicating with an extension, not when saving? Another possibility is that the embroidery design output functionality could be an "output" extension, but I haven't played with that. I'm under the impression that the user would have to choose a folder and file name every time they wanted to save using an output plugin, which would be a prohibitively bad user experience for ink/stitch since it's common to repeatedly re-render the design file until you get it right. "Dependency hell" is another big issue for extensions. Pyinstaller is very promising as a solution to this problem! I highly recommend mentioning it in the inkscape extension documentation. Trying to explain to users how to install python modules required by an extension is destined for failure. On Windows and Mac, the problem is even worse, as Inkscape bundles its own Python. It's very confusing for users that they can do `pip install -r requirements.txt` but then inkstitch still can't load its dependencies, because they didn't install the requirements in Inkscape's bundled Python. Installing modules for Windows's Python is especially complex. Ultimately, we desire a completely smooth, painless installation process for our users. Currently, installation involves downloading a ZIP/tarball and uncompressing it in Inkscape's extensions directory. This is pretty smooth, and we could refine it even more by distributing it as a self-extracting installer. Anything more complex than uncompressing an archive risks losing users before they even try our extension. One final thing: Inkscape's extension model is powerful and nifty, but of course it's also limiting. We've gone to a lot of lengths to work around this limitation, including popping up an entire UI of our own in one of ink/stitch's bundled extensions. Still, we constantly bump into the inability to integrate more directly with Inkscape, by adding tools or the like. I'm sure you've encountered this idea before. :) If Inkscape introduces such functionality, we'll be among the first to try it out. > Also, do you have any pictures of something embroidered using the > extension?
