glyphsets 0.6.14

A python API for evaluating coverage of glyph sets in font projects.

Attention: Repository under transition

The assembly of character sets is currently undergoing a transition from the previous approach of using the glyphsets command and data.json as a database to using the gflanguages package as the database and assembling .nam and other files from that.

[!NOTE]
Please see GLYPHSETS.md for an up-to-date description of the state of the new language definitions.

How to assemble glyphs and characters using the new approach

1. Define the glyphset in the Python module in Lib/glyphsets/definitions/__init__.py with language codes for your character set.
2. Optional: Have a .stub.nam file under GF_Glyphsets/*/definitions/ for your character set, containing encoded characters that you want to see included that can't be inferred from the gflanguages definitions.
3. Optional: Have a .stub.glyphs file under GF_Glyphsets/*/definitions/ for your character set, containing unencoded glyphs that you want to see included.
4. Update all glyphsets using sh build.sh, see below for details.

The final .glyphs files are the sum of gflanguages + .stub.nam + .stub.glyphs. See chart below.

[!NOTE]
glyphsets uses the version of gflanguages that's currently installed on your system to query for characters per language. This enables you working on both packages locally at once. In any case, make sure that the gflanguages package is up-to-date on your system.

[!NOTE]
Bonus points: Sadly, in the creation of the .glyphs files, it's not possible to exactly recreate the glyph sorting that Glyphs.app uses by default, so the .glyphs files look a bit different from what's expected. If you care, please open every freshly adjusted .glyphs file in Glyphs.app, select all glyphs, and run "Update Glyph Info" from the "Glyphs" menu on them to sort them and save the file. But the files will work as-is in any case.

Data flow visualization

Visualizes in a simplified way how the various data sources are combined into a final glyphset, then rendered out to various format. This process is repeated for every glyphset defined in Lib/glyphsets/definitions/__init__.py.
