Verified usage

Verified import paths — ran on the pinned version, not inferred.

Font

✓ from babelfont import Font

✗ from babelfont import Babelfont

Load a TrueType font, inspect name and glyphs, then export to UFO.

from babelfont import load # Load a font file font = load("example.ttf") # Print font name and glyph count print(font.name, len(font.glyphs)) # Access a specific glyph glyph = font.glyphs["A"] print(glyph.unicode, glyph.width) # Save as UFO font.save("example.ufo")

Debug

Known issues

breakingv3.0 replaced the old Font object with Babelfont class; direct instantiation of Font is removed.

fix

Use from babelfont import Babelfont or the load function.

affects: >=3.0

breakingThe glyphs attribute is now a dict-like mapping, not a list. Indexing with integer may fail.

fix

Access glyphs by name: font.glyphs['A']. For iteration, use list(font.glyphs.values()).

affects: >=3.0

gotchaBabelfont may emit many log messages; by default it logs to stderr. This clutters output in scripts.

fix

Disable logging: import logging; logging.getLogger('babelfont').setLevel(logging.ERROR)

affects: all

gotchaWhen loading fonts, some format-specific attributes might be missing; always check with hasattr or dict access.

fix

E.g., use getattr(font, 'variations', None) or font.glyphs['A'].get('width')

affects: all

deprecatedThe low-level fontforge backend is deprecated and will be removed in v4.0.

fix

Switch to the default fonttools backend. Set backend explicitly if needed: load('file', backend='fonttools')

affects: >=3.0
