i-can-variable-font's Issues

Mention pre-compiled binaries for fontview

The README says: “Mac previewer (requires running a script to build the application)”. Actually, if you want, you also just take the pre-compiled binary. When using the app for the first time, use the right mouse button (or control-click) to confirm that you’re ok with opening an app downloaded from the Internet.

TTX dump can't be recompiled

This might be caused at the TTX/FontTools side of things, but reporting it for completeness sake:

When I follow the instructions and dump the resulting font with TTX/FontTools, I get a nice varibox-VF.ttx file. But when I want to compile this back to a font, I get:

Calling varLib

Heya,

Recent versions of fonttools ship with a shell command called "fonttools". Instead of invoking python fonttools/Lib/fontTools/varLib/__init__.py my.designspace you can now just say fonttools varLib my.designspace

THANK YOU.

Hullo, thank you for making this. It's been really had to find easily understandable information about creating variable fonts, thanks for putting the time into this example. 💯

I did have an issue installing fontmake where I had to re-install pip because of TSLv1.0/1.1 pip issues that took effect in April, it's a little obscure for the readme, but just wanted to mention in case anyone else has this issue.

Mostly this isn't an official issue just wanted to say thanks!

"rtf" typo

Typo:
fontmake -o rtf-interpolatable -m path-to-your-designspace-file
should be
fontmake -o ttf-interpolatable -m path-to-your-designspace-file

Small issues with the installation instructions

I followed the instructions on a Mac (El Capitan), some comments:

Add to docs that you need to install TTX/FontTools
(On Mac) pip install fontmake works as well
python env/lib/python2.7/site-packages/fontTools/varLib/__init__.py path-to-your-designspace-file is python /usr/local/lib/python2.7/site-packages/fontTools/varLib/__init__.py path-to-your-designspace-file on (my?) Mac
"with -GX in the name" → "with -VF in the name"

Superpolator rules

Superpolator substitution rules (http://new.superpolator.com/documentation/rules/) get lost somewhere between the designspace file and the generated v-font. Or perhaps the generated fonts are legit and the apps that currently support v-fonts just don't support that feature yet?

The rules do get lost at the moment. I need to add them to the designspace export, and then they need to be supported by varlib. FWIW, this feature is not yet fully supported in the FDK feature language either. I'm sure that will happen.

Update tutorial to consider `fontmake -m [...] -o variable`

I'm looking for examples on how to best setup a .designspace so I can generate plain old instances as well as variable fonts. Fontmake seems to support the -o variable switch to do the varLib fudging for you. I guess the tutorial can be updated to use it?

FontTools is a community effort...

Thanks for mentioning my name with FontTools, and while I wrote a lot of the initial code, it's a true community effort these days, with major roles for @behdad, @anthrotype and @brawer. I didn't write a single line of code for varLib for example :)

Browser recommendation needs updating

The link for "Requires a browser that supports Variable Fonts" is currently not valid, since WebKit Nightly and Safari Tech Preview stopped supporting variable fonts on macOS (except on macOS 10.13 High Sierra beta). The best browser to link to now is Chrome Canary, which works on multiple platforms, but users also need to enable "Experimental Web Platform Features". Feel free to link to How to get variable fonts working in Safari, Chrome and Firefox, which explains the browser options.
