v1.0.0

• Removed all remaining old code after diffenator2 got refactored
• Pulled in 3 additional African language definitions from gflanguages v0.6.0. GF_Latin_African glyphset didn’t change as a result of that, only its "Character Sequences" definitions increased from 722 to 746 (commit 8b93034).

v0.6.20

• Added language_code definition for GF_Latin_PriAfrican to allow shaping tests
• Added glyphsets coverage CLI command that prints a font's glyphset coverages
• Reworked glyphset coverage calculation in get_glyphsets_fulfilled(); now based on characters per glyphset that are unique when compared to GF_Latin_Core.

Coverage Calculation Changes in Detail:

Previously, the coverage percentage as returned by get_glyphsets_fulfilled() would calculate all the font’s characters as a percentage of a glyphset’s total characters. Fontbakery (among others) would then treat a glyphset as covered as soon as 80% of characters are present.

This generally worked, but created unwelcome overlaps as soon as glyphsets were too similar to each other. The newly redefined GF_Latin_PriAfrican glyphset, for example, has only 34 additional characters compared to GF_Latin_Core, as revealed by the command glyphsets compare GF_Latin_Core GF_Latin_PriAfrican.

GF_Latin_Core on the other hand currently has 324 glyphs, and so a font that covers GF_Latin_Core also covers 90% of GF_Latin_PriAfrican and would therefore be counted as supporting GF_Latin_PriAfrican by accident, without actually supporting it, resulting in loads of unwelcome reports by Fontbakery’s shape_languages check.

The new calculation is based solely on additional characters when compared to GF_Latin_Core. Similar to the compare command, additional characters are calculated in a first step (Ŋ ŋ Ɓ Ɔ Ɗ Ɛ Ƙ ƙ Ɲ Ƴ ƴ Ǹ ǹ ɓ ɔ ɗ ɛ ɲ Ḿ ḿ Ṅ ṅ Ṣ ṣ Ẹ ẹ Ị ị Ọ ọ Ụ ụ for GF_Latin_PriAfrican vs GF_Latin_Core), and then it is calculated how many of those characters a font supports, which is a significantly more accurate calculation.

Since get_glyphsets_fulfilled() is hosted here inside glyphsets, no changes to external implementations are required as the API didn't change, only the calculation of the percentage. Fontbakery still uses 80% as the threshold, but now based on a more accurate calculation.

v0.6.19

• Removed unnecessary glyphsLib import that caused trouble on fontbakery.com

v0.6.18

• Added back a few unencoded glyphs to Latin_Plus and Latin_Vietnamese that went missing in the recent data transition (Issue #166)
• Added language_code definition for Latin_Vietnamese to allow shaping tests
• Added glyphsets compare CLI command

v0.6.17

Reinstate GFTestData

v0.6.15

• Excluded colonizer languages from African glyphset via new exclude_language_codes to prevent unnecessary glyphs (e.g. "ß") from appearing in the African Latin glyphset
• Reintroduced glyphsets filter-list command to generate custom filter lists

v0.6.14

Added language codes for additional glyphsets that can be now covered in Fontbakery's shape_languages check.

In total, these glyphsets are now covered:

• Latin African+Core
• Cyrillic Core
• Greek Core
• Arabic Core+Plus

v0.6.13

• Made human-readable description available in /GLYPHSETS.md
• Changed API, consequently updated Fontbakery's usage of the API
• Includes the new GF African Latin glyphset

v0.6.11

Merge pull request #151 from googlefonts/arabic-charsets
