Incorrect Master IDs?

Scripting
1

Hi there!

Sometimes when I ask for a GSmaster’s ID via python, I receive a value such as ‘master01’, rather than a long alphanumerical string, as is the case with a ‘new’ file/master in a Glyphs file.

Then when I ask for the master at ‘master01’, Glyphs throws an error claiming that master is not there.

Is this something that changed about the API/Glyphs? Were older files (prior to ~ 2 years ago) using master IDs in the ‘master__’ format?

Thanks!

The master id can be something like “m01” or those long alphanumerical string. That doesn’t matter. They only have to be unique for each master. But are different for each font.
