@frederik I dream of the day someone would convert fontTools feature ast objects to json and we won't use fea file anymore.

hello @paulvanderlaan, it turns out the problem is not related to Mechanic2 at all, but to old macOS 10.10 which gets confused when multiple certificates are attached to a domain – this causes Safari and macOS to think that the certificate is invalid (it works in Firefox and Chrome though). the good news is that you can use an older version of Mechanic (zip link) which is a bit slower but can display extensions from the Extension Store on macOS 10.10. thanks @frederik for looking into it!

@jansindl3r That is possible... there were some bug fixed related to trial and student versions of extensions. Will send @erik new student licenses for MM and PP. @erik will need to compile a fresh version of Skateboard for students ( @tal )

and with a script its super easy: # load two fonts fontWithKerning = OpenFont() fontWithoutKerning = OpenFont() # clear and update the kerning with data from # the font with kerning data fontWithoutKerning.kerning.clear() fontWithoutKerning.kerning.update(fontWithKerning) # clear and update the groups with data from # the font with kerning data fontWithoutKerning.groups.clear() fontWithoutKerning.groups.update(fontWithKerning) enjoy!

Updated Matrix machine! Thanks again @gferreira

It might help to just use the Monospaced System Font: https://developer.apple.com/documentation/appkit/nsfont/3042659-monospacedsystemfont

Is there anywhere I might read more about scripts involving Metrics Machine? The next version of the current extension will have a scripting API. We're going to release it very soon.

Thanks, @tal!

All groups except pulic.kern groups should be shown in the reference group editor.

Hooray! This works perfectly. Thank you so much, Tal!

In RF3 the kerning icon in a font window is not MM anymore, RF just shows a kerning icon and opens RoboFont default Kern Center. However it can happen MM is listed ‘Edit With’, apps supporting UFO (similar as in Finder).

This will be fixed in the next version. It's in beta test now and will be released soon.

@frederik Ah, ok. That sorta makes sense. I imagine there is some deep logic to figure out here. In the mean time, could the wording perhaps match the group editor and exception dialog? At the moment it's Side 1 | Side 2 in the group editor, and Kern 1 | Kern 2 in the exception dialog.

Oh — thank you! Am I missing a the manual somewhere? ⌘+i = iddqd ;-)

TL;DR a long text string in MM preview window slows it to a crawl. Can it be faster? When I kern a pair of letters, I have a string of words in the preview window to check them in context. For example, if I’m kerning an Upper/Upper list and I’m on J/UC, I'll paste this string into the window: J JARN ENAJER HEBJORN HOCJERM HODJERN REJOINER FJERNISCHE LAKJERNIS REJOINER KLIPJENNI MARJORAM SJORNE MATJINKO JUNIPER HUJIME HIVJINE HIJVINE HIJWINE HIWJINE HIJYINE HIYJINE HIZJINE HIJZINE A string this long really slows the extension to a crawl. The old standalone MM app used to handle a string like this. Is there any way to beef up the extension somehow? I’d really appreciate it!

I noticed Batch Export has been added to Metrics Machine. Thank you! I think I've used it a dozen times in the past week and every time I use it I am so happy.

@gferreira ok thank you, I have the old metrics machine.
