Prerequisites for using Inkscape UI free, GSOC 2018
by Kuntal Majumder
Hi,
I am Kuntal, some of the people might know me from IRC. I was looking
into the GSOC 2018 ideas list. Loved the idea of making Inkscape go UI
free [1]. I would love to give it a try, I have used CMake to compile
programs in past, but never wrote a CMakeLists file. I was also working
on my own build system [2], which is currently not that nicer, well I am
yet to learn how to write parsers, :P.
Also whenever I used Inkscape, I used to jump to and fro from Inkscape
to Calculator to get the correct ratios, wouldn't that be better if we
can put expressions inside text-boxes and they evaluate by themselves.
If the previous mentioned idea is viable for GSOC, I would love to pitch
for it.
Thanks
Kuntal (hellozee)

Eager Python Developer - GSoC
by Tonya Sims
Hello everyone!
My name is Tonya, I'm a junior to mid level Python developer and plan on
applying for GSoC I downloaded Inkscape on my Mac and played around with
it. A very cool application!
What are your most urgent needs? Are your extensions built in Python? I was
trying to brainstorm some ideas for a new extension and may need more time
unless there's something you could suggest? Also, I'm learning Django and
could help out with the website, let's say a new bug tracking system (not
that you need one) but just brainstorming.
Anyways, looking forward to everyone's replies and will start working on my
application.
Cheers,
Tonya Sims

Hackfest update
by Máirín Duffy
Hi everyone,
I wanted to give you a heads up about a couple of things regarding the
hackfestsite -
- Onthe Monday, Red Hat is also going to host a SpinachCon event on the
other side of the space we'll be in. It's a 4 hour event (from 1-5 pm
IIRC) where free software projects can come and have their software
usability tested. The organizers (including Deb Nicholson) would be more
than happy to test Inkscape as part of the event if there's any interest
in that. If there are specific components you'd like tested, I can help
create a testing plan.
- There may be another co-hosted event in the morning on Monday, still
sorting the details out.
- On the Tuesday and Wednesday, Red Hat is also hosting an event that
will involve a workshop and hacking on amedical image processing system
that we're working on with Boston University and Boston Children's
Hospital. It's a really cool project. If anyone attending has an
interestin learning more, you are more than welcome to get involved.
I don't expect either event to be disruptive to the hackfest; it's a
large space and we have two floors and a variety of different areas to
work inand a lot of seating. I just wanted to let you know ahead of
time, especially in case you wanted to take advantage of SpinachCon
testing.If you have a preference towards the type of space you'd prefer
(large conference room with door; open meet up space; lounge-y type area
with couches and tables and chairs) I can note in our reservation now
that's the part we'd like for the Inkscape hackfest; if you're not sure
I can give youa tour when you get here on the Monday morning and we can
figure out which end of the office to claim.
Cheers,

calligraphy tool solved
Hi Yale,
Thanks for working on this problem, it seems to be one of our top
blockers for the 0.93 release at the moment, so your work is very much
appreciated.
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
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

Wow! 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
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.
