Prepare Fraunces for Google Fonts

[arrowtype]

Some of these fixes will follow the work from Viviana at https://github.com/vv-monsalve/Fraunces/issues/2

• Update “Soften” axis to “Softness” and “Wonk” to “Wonkiness” to align with axis registry
• get static & variable fonts to build with expected family & style naming (ef8d2b8)
• confirm axis names & defaults at Confirm axis defaults undercasetype/Fraunces#247; change if required
• test gftools-packager for making a PR
• change opsz default to min (Opsz bug in Firefox undercasetype/Fraunces#208)
• Add step to build STAT table based on Marc’s script for Roboto
• add ttfAutohint to venv, then rebuild with this. Also add to readme how to get this dependency. OR add gftools fix-nonhinting (I’ve done the latter, but I can change to add hinting if it is recommended)
• get fraunces & fraunces italic working in the same font menu family
• Probably: remove name IDs that are no longer needed due to simplified fvar
• check that Unicodes are correct for all glyphs – unsure what the best way to do this is ... maybe Marc’s OCR scripts?
• MAYBE: add a way to set font versions?
• MAYBE: abbreviate style naming to avoid exceeding 27 char length
• MAYBE: change Softness style names to something alphabetical (Make full release (variable + static) for GitHub, then link to it from Fraunces site undercasetype/Fraunces#186)

Assumptions on naming:

• WONK axis name should be “Wonky”, per Proposal: “Wonkiness” axis name should be “Wonky” due to its binary usage; "Normal" name should be "NonWonky" google/fonts#2741
• WONK STAT names should be Wonky (elided) and NonWonky Proposal: “Wonkiness” axis name should be “Wonky” due to its binary usage; "Normal" name should be "NonWonky" google/fonts#2741 (comment)
• SOFT axis instance names should be Sharp, Soft, & ExtraSoft (Why do style names include spaces in the Axis Registry, but not in practice? google/fonts#2742)

Fontbakery fixes

• find out if it is okay to exceed 27 chars in variable font name
  • This probably won’t be relevant once the naming is fixed to reflect the default, simplified instance names

Whitespace naming

• prevent com.google.fonts/check/whitespace_glyphnames: Glyph 0x0020 is called "uni0020": Change to "space" – probably by adding --no-production-names arg to fontmake

Now that I have added --no-production-names, I now get the message * WARN: Glyph 0x00A0 is called "nbspace": Change to "uni00A0" [code: not-recommended-00a0].

Not sure if this is worth worrying about...

Optical size default must be 9pt

• WARN: The "opsz" (Optical Size) coordinate on the "Regular" instance is recommended to be a value in the range 9 to 13. Got 144.0 instead.
  • default for range set to 9, but mastering/scripts/removeUnwantedVFInstances.py removes all instances but those with opsz=144... will investigate further
  • SOLVED by changing opsz values for final instances in variable designspaces

Description length

• get shorter description or written exemption FAIL: DESCRIPTION.en_us.html must have size smaller than 1000 bytes.
  – asked at FontBakery requires the DESCRIPTION.en_us.html to be <1000 bytes (i.e. <1000 characters, including HTML) undercasetype/Fraunces#249

com.google.fonts/check/ligature_carets

add ligature carets Actually, I have added these to to UFOs, but ufo2ft doesn’t yet support this, so this is pointless. As was said at undercasetype#206:

Ligature carets are now included in the UFO spec, but I wasn’t able to find an indication that they are handled by ufo2ft or fontmake. related issue

Fontbakery false fails:

• com.google.fonts/check/usweightclass – * FAIL: OS/2 usWeightClass is '900' when it should be '400'. [code: bad-value] Add VF check to ensure os/2 weightClass is same as default wght axis position fonttools/fontbakery#2364

[WIP – more to come here]

[arrowtype]

Useful regex recipe to match & update UFO paths via find & replace:

Fraunces9ptExtraSoft(.*?).ufo
Fraunces9ptS100$1.ufo

.* or .*?. The first one is greedy and will match till the last "sentence" in your string, the second one is lazy and will match till the next "sentence" in your string. source

Process to fix style names but keep proper UFO paths:

1. Replace S000 with Sharp to update style names (though this also breaks paths)
2. Then replace Fraunces(.*?)Sharp-(.*?).ufo with Fraunces$1S000-$2.ufo to fix UFO paths
3. Replace Fraunces-(.*?)Sharp(.*?).ufo with Fraunces-$1S000$2.ufo to fix UFO source paths
4. Repeat for S050 and S100

(etc)

Changes made:

• Removing ".ufo" and replacing Sxxx in instance name properties.
• Setting instance ufo names to use readable Sharp/Soft/ExtraSoft names, to output better static TTF filenames

Lingering challenge

Some names are getting a space removed between the opsz and SOFT labels. This formation isn’t anywhere in the designspaces, so it is likely due to a regex issue in mastering/scripts/fixNameTable.py.

• Name 1: Fraunces 9ptExtraSoft
• Name 4: Fraunces 72ptExtraSoft Bold

The problem: the familyname is taken from a parsed filename, with the expectation that the filename will only have a family, single style, then weight name: return_familyname(filename)

Fraunces/mastering/scripts/fixNameTable.py

Lines 42 to 61 in 9551c8d

	def return_familyname(filename):
	name = return_filename_no_extension(filename).split("-")[0]
	parts = []
	i = 0
	previous = None
	for s in name:
	if unicodedata.category(s) in ['Lu', 'Nd'] and not unicodedata.category(s) == previous:
	previous = unicodedata.category(s)
	part = name[:i]
	if part:
	parts.append(part)
	name = name[i:]
	i = 0
	i += 1
	parts.append(name)
	parts[-2] += parts[-1]
	del parts[-1]
	return ' '.join(parts)

The fixNameTable script doesn’t seem to have an advantage for Fraunces static name tables ... BUT it also adjusts the head and OS/2 tables, so it probably does make some useful changes there for style-linking. I probably need to adjust the script to better handle the basic stylename, rather than scrapping it.

Further fixes to fixNameTable.py

Variable

"Italic" is in the family names in italic variable fonts.

# TODO: remove "Italic" from the family name

        # nameID1  = Fraunces Italic 9pt ExtraSoft Black        # remove " Italic", then add to end " Italic"
        # nameID3  = 1.000;UCT;FrauncesItalic-9ptExtraSoftBlack # remove "Italic", then add to end "Italic"
        # nameID4  = Fraunces Italic 9pt ExtraSoft Black        # remove " Italic", then add to end " Italic"
        # nameID6  = FrauncesItalic-9ptExtraSoftBlack           # remove "Italic", then add to end "Italic"
        # nameID16 = Fraunces Italic                            # remove " Italic"

Statics

"None" is in static font family names for RIBBI fonts, due to a try/except block being used where it actually needs an if/else block. (FontMake returns a NoneType if a nameID is missing, rather than an error.)
