This removes some boilerplate code, and also helps when using static type checkers like mypy.
The typing.NamedTuple class was added with python 3.6 which is our min required python, so we are good.
since we use pytest-randomly to randomize the test execution, depending on when
this specific test is executed, it may have the side effect of configuring
the global logging configuration, causing other tests that capture logging
messages to fail.
E.g. see https://travis-ci.org/fonttools/fonttools/jobs/545680550
* Added getter (in the form of a property decorator) for T2Charstring.vsindex. Fixes endless compile loop in some circumstances.
Fixed bug in mutator: need to remove vsindex from snapshotted charstrings, plus formatting clean up
* Fix for subsetting HVAR tables that have an AdvanceWidthMap when the --retain-gid option is used. Needed to make subset_test.py::test_retain_gids_cff2 tests pass.
* in varLib/cffLib.py, add support for sparse sources, and sources with more than one model, and hence more than one VarData element in the VarStore.
CFF2 source fonts with multiple FontDicts in the FDArray need some extra work. With sparse fonts, some of the source fonts may have a fewer FontDicts than the default font. The getfd_map function() builds a map from the FontDict indices in the default font to those in each region font. This is needed when building up the blend value lists in the master font FontDict PrivateDicts, in order to fetch PrivateDict values from the correct FontDict in each region font.
In specializer.py, add support for CFF2 CharStrings with blend operators. 1) In generalizeCommands, convert a blend op to a list of args that are blend lists for the following regular operator. A blend list as a default font value, followed by the delta tuple. 2) In specializeCommands(), convert these back to blend ops, combining as many successive blend lists as allowed by the stack limit.
Add test case for sparse CFF2 sources.
The test font has 55 glyphs. 2 glyphs use only 2 sources (weight = 0 and 100). The rest use 4 source fonts: the two end points of the weight axis, and two intermediate masters. The intermediate masters are only 1 design space unit apart, and are used to change glyph design at the point in design space. For the rest, at most 2 glyphs use the same set of source fonts. There are 12 source fonts.
Add test case for specializer programToCommands() and commandsToProgram by converting each CharString.program in the font to a command list, and back again, and comparing original and final versions.
Somehow we forgot to replace round -> otRound in arrayTools.calcIntBounds.
This function is used by glyf table to compute the glyphs' bounding boxes.
We already use otRound (aka 'int(math.floor(v + .5))') to round glyph
coordinates upon compiling glyf table. So the use of python3's round
in calcIntBounds was producing inconsistent roundings between the glyph
coordinates and the glyph bbox (sometimes, i.e. only when the glyf table
contains float coordinates, e.g. after instantiating with varLib.mutator).
* a charstring is not guaranteed to end in an operator, so the final bytecodes 11 and 14 can be part of an encoded numeric value; so remove 'return' or 'endchar' at the program level instead of bytescode
* move non-CFF2 test+error to elif clause of earlier isCFF2 test
Fixes the remaining issue from #1451
* fix two cases where pathlib.Path objects were not accepted
* make macRes reader accept os.PathLike objects
* use __fspath__ explicitly to support os.PathLike paths
* use __fspath__ explicitly to support os.PathLike paths
* convert tmpdir to str
* only test pathlib.Path on Python 3.6 and up
