we tell GzipFile to write the MTIME field to zero so that the compressed output is reproducible and doesn't change depending on when the data is compressed.
This is based on bungeman's https://github.com/fonttools/fonttools/pull/2627
Previously, an entire `SVG ` table would be marked as compressed if any
of the decoded SVG documents in it were compressed. Then on encoding all
SVG documents would be considered for compression. The XML format had no
means to indicate if compression was desired.
Instead, mark each svgDoc with its compression status. When decoding
mark the svgDoc as compressed if the data was compressed. When encoding
try to compress the svgDoc if it is marked as compressed. In the XML
format the data itself is always uncompressed, but allow an optional
`compressed` boolean attribute (defaults to false) to indicate the
svgDoc should be compressed when encoded.
We also try to make sure that older code that relies on docList containing
sequences of three items (doc, startGID, endGID) will continue to work
without modification.
* Add default auto doc options
* Ensure all references are unique
* Use anonymous links to avoid duplicate references
* Remove default options, fix wrong module name
* Don’t index repeated class
* Remove repeated classes included through automodule
* Fix warnings
* We don’t use our own static directory
* Correctly format XML in docs
* Fix indentation
* Fix overline
* Bring TOC to top
* Fix definition list
* Offset definition lists and examples
* Fix erroneous markup
* Fix markup
* Already included in automodule
* Fix args markup
* Correct markup for example
* Don’t reindex repeated module
* Correct XML code block markup
* Fix markup errors, change example to doctest
* Correct list markup
* Make ttx docstring both valid RST and valid help output
* Various other boring markup fixes
* Fix example indenting
* Make docstring valid RST and valid help output
* Mock import for reportlab
* It’s ok if manual links don’t appear in toctrees
* Oops typo, I guess doctests are useful
* Replaced all from ...py23 import * with explicit name imports, or removed completely when possible.
* Replaced tounicode() with tostr()
* Changed all BytesIO ans StringIO imports to from io import ..., replaced all UnicodeIO with StringIO.
* Replaced all unichr() with chr()
* Misc minor tweaks and fixes
Set font['SVG '].compressed=True to enable. Here's a snippet to convert a
WOFF-compressed SVG+OpenType font to a compressed SVG+OpenType non-WOFF font:
from fontTools.ttLib import TTFont
font = TTFont("NotoColorEmojiSvg.woff")
font['SVG '].compressed=True
font.flavor=None
font.save("NotoColorEmojiSvgCompressed.ttf")
The latter hits the __eq__ method and can fail because we now
do not allow comparing objects of different types.
For example, was failing subsetting Andika-R.ttf.
For the sake of separating py23 effort from feature changes,
I'm reverting the name table XML dump format back to what it
was. I will clean it up after py23 is merged.
Our footprint in the Python module namespace is all under
fontTools now. User code importing sstruct should be updated
to say "from fontTools.misc import sstruct".
