- mutators for info, kerning and glyphs are lazily constructed. Only make them if they're asked for.
- getInfoMutator() makes / returns info mutator.
- getKerningMutator() makes / returns kerning mutator
- getGlyphMutator() makes / returns glyph mutator
- loadFonts attempts to load the master UFOs and determine the defautl font by looking for the copyInfo flag, or if that is not found, by using mutator's findBias. Will warn if there is a conflct, but the copyInfo flag is leading.
- makeInstance() returns a font object for the asked location. You can decide to save it or not elsewher.
- generateUFO() makes UFOs on disk for all defined instances.
Still largely untested. Note: this requires an updated mutatorMath.
- aims to do work the same way as mutatorMath.ufo.document
- generate all instances as UFO
- handle glyph masters, info, kerning, lib
More testing is needed.
We only define 'round3' for PY2 and 'round2' for PY3, and also make sure 'round3' is always an alias of
the built-in 'round' on Python 3; and similarly 'round2' is an alias of built-in 'round' on Python 2.
Thus, for clarity, one can do:
from fontTools.misc.py23 import round3 as round
or
from fontTools.misc.py23 import round2 as round
and be certain that the fast built-in implementation will be used on the
respective python major version.
Commits 3063def and 5b47971 introduced a separate fontDictOperators list for FontDict, only listing those TopDict key/value pairs that are actually used in the FontDict context. It provided a fallback that TTX files containing such "useless" key/value pairs would not be rejected.
However, the code still rejected binary fonts that contained such values, even though it didn't before, and yes, such fonts exist. Also: such fonts are not broken per spec, they just contain some fields that otherwise no one ever looks at, so it's a little harsh to reject them.
This patch removes most of the special FontDict code, and uses everything from TopDict, *except* the order attribute: it sets that to a list of the relevant keys for the FontDict. The effect of this is that "useless" key/value pairs are ignored, not just upon reading XML, but also upon decompilation and compilation of binary fonts. It improves on the previous XML reading behavior in that it no longer silently ignores key typos in the TTX input.
Ideally, we would *output* everything that is actually in the FontDict to TTX, and only ignore the values when compiling, but I didn't find a clean solution for that, so I decided to just fix the issue.
- independent reader / writer object for designspace documents.
- imports and exports easy to subclass objects for instance, source and axis data.
- roundtrips
- intended to be compatible with use in MutatorMath, Superpolatpor and varlib.
Fixes https://github.com/fonttools/fonttools/issues/739
for now, though proper fix is more complicated.
This was hit now because the subsetter was changed a while back
to retain script systems even if empty... I don't like that.
