HTLetterspacer script

Scripting
1

Hello,
i recently bought glyphsapp, really enjoy it.
so after playing and starting some typefaces, i did installed HTLetterspacer for testing purpose.
it worked fine, i thought it made some good adjustments to my spacing, then worked a lot on the font.
add a second master, and thought it was time to use HTL again.

but it doesnt run anymore i get this in the macro window :

Start

    from contextlib import redirect_stderr, redirect_stdout
ImportError: cannot import name redirect_stderr
End

im using latest glyphs Version 2.6.1 (1230)
have no idea what changes i made since, i may have tried to install other scripts, not sure

Better open an issue in the LetterSpacer repository.

ok, thank you.
Will do this.
But im worried because I also installed kernkraft from the plugin manager, and its not there, even if it shows as installed in the manager.
so i removed it and installed it manually in the script folder. now i see the menu, but nothing, i just got a ’ start end ’ in the macro window.

When clicking on the install modules in the prefs/addons i get :
The modules could not be installed
Could not load the modules.

Kernkraft shows up in the Glyph menu after installation. Did you restart the app after you installed?

and btw i removed HTletterspacer from the script folder.

This is not a LetterSpacer error. Seems to be one of the plug-ins you have installed.
Perhaps try reinstalling your modules?

ok thank you mekkablue,
i removed robofab, vanilla, fonttools. reinstalled them in the pref/modules.
same problem. So i removed one plugin after another, and closing/relaunched glyphs after each one.
Turn out it was kern-a-lytics causing this error message, so i got rid of it, + i dont need it.

Still no luck with HTLetterspacer tho, no idea what i did wrong to cause it not to work anymore.

I had same issues before about this, maybe it’s some kind of error in newest fontTools packages. So I downloaded and install the old version of fontTools here: https://pypi.org/project/fonttools/3.21.1/
and the hard way is copy the fontTools folder fonttools-3.21.1 > Lib > fontTools into Glyphs Script folder.
I hope it helps.

it works, i did exactly that, installing the 3.21.1, and hard copy the folder into the fonttools fodler, and everything seems to works again, HTLetterspace at least is working again. thanks a lot gumpita!
