"Oops, this parser is just broken"

[jenskutilek]

I tried to compile my Sudo font with fontc, but it fails without any specifics:

fontc Sudo.glyphs
Font IR error: 'Unable to parse "Sudo.glyphs": Unable to read glyphs file: Unable to parse Sudo.glyphs: Oops, this parser is just broken'

I converted the original .glyphspackage file to .glyphs, attached.

Sudo.glyphs.zip

thanks. Could you try with RUST_BACKTRACE=1 env variable and paste here what you get?

[anthrotype]

actually RUST_BACKTRACE=1 would not work in this case as this is not a panic. RUST_LOG=debug maybe

[anthrotype]

I put a few println! before the SomethingWentWrong error which gives the Ooops, and I think it's the "disabled = 1" key in some of the custom parameters that is making it fail. So the glyphs-reader parser currently doesn't support disabled custom parameters. Looks like it's a known issue #312

If I remove those disabled custom params, I get another error but probably better to file a separate issue for that.

[anthrotype]

ideally we should support parsing disabled custom params, but at least this generic error message should be made clearer, more specific

Thank you for testing!
