While False does get the job done, the value is not always treated as
a boolean. It is overloaded so that 1 or greater is True, but more than
1 has a different meaning than 1. Hence usage should always be as an
integer as documented so that it's clear(er) this isn't just an on/off
toggle.
* Add custom table packer/unpacker registry
* fix documentation for getTableClass(): it will never return None
* add unregisterCustomTableClass(), mostly for testing
This reverts commit 690080b14d9a4f193092ffc172a39b3e212d307c.
We keep 16-bit GlyphIDs for COLRv1 tables, at least for now
https://github.com/googlefonts/colr-gradients-spec/pull/24
I keep the GlyphID32 converter in case we may need it in the future.
Fix for #1985:
* ensure that the AxisNameID in the STAT table is not less than 256. This needed an additional argument to the addMultiLingualName() name table method.
* fvar axis name IDs must also not be less than 256, just like STAT axis names.
_getUnicodeRangeSets used to calculate sets containing lots of numbers, only to
get intersections between a set and ranges. Creating and manipulating a lot of
big sets requires a lot of memory.
The function has been replaced by _getUnicodeRanges, returning a list of range
starts boundaries and a list of range stops + corresponding bits.
Tests on intersectUnicodeRanges save about 130 MB (!) of RAM, with no
significant speed penalty.
Instead of copying to BytesIO, we can return the file name in getstate and reopen the file in setstate. This keeps the TTFont truly lazy as it avoids the extra copy
* when reading from binary, name.string may be an encoded bytes sequence: we should call toUnicode() before we compare to the requested string
* fix expected output
Note UI change : `fonttools varLib.models` now takes prefixed options `-d` or `-l` instead of guessing the intended feature from the number of arguments.
We have a number of command line tools which are somewhat opaque. (varLib.models in particular was very confusing.) This ensures that they all use argparse to have a consistent interface, and all have --help documentation which at least details their parameters, and hopefully therefore gives more of a clue about what they do. Those which use logging have had a command-line logging parameter added.
This adds a `help` verb (and `--help` option) to the `fonttools` command line tool. Submodules will be listed in the help text if they have an importable `main` function with a docstring, and `main`'s docstring will be used as the one-line description for the help text.
* add nameTable.findMultilingualName(), to find an existing multilingual name
* Make addMultilingualName() reuse nameIDs if possible when asking for a new nameID, by calling findMultilingualName()
