Plugin importing data from a binary format when opened in Glyphs

Scripting
1

I’m extending the MATH Plugin to read MATH table and import it into the data the plugin uses (some stored in master and glyph userData, others as anchors).

I already have a callback for DOCUMENTOPENED, so I open the font there using GSDocument.filePath and import the data into the GSFont.

All is good but I have some questions/issues:

  1. Is this the right approach or there is a better way?
  2. The causes the font and the affected glyphs to be Edited, but since everything is imported and the user didn’t manually change anything, I want to avoid this. Is there is away to revert the edited status of the font and the glyphs?

  1. Yes.
  2. You can clean up after yourself:
from AppKit import NSChangeCleared
for g in font.glyphs:
    g.undoManager().removeAllActions()
    g.updateChangeCount_(NSChangeCleared)
font.undoManager().removeAllActions()
font.parent.updateChangeCount_(NSChangeCleared)

This works, thanks.

Another question. If I’m opening a font collection file, Glyphs will ask the user to select a font from the collection. How do I know which font was selected to open it as well?

There is currently no way to do that directly. Maybe you can recognise it from the fontName?

I added the fontIndex to the font.tempData["TTCFontIndex"]

I guess, but I wanted to check for a simpler solution first.

Thanks. That is enough for me, I don’t mind it working only in cutting edge for now.

Did this make it into release?
