Info for developers

Where glyphs are defined

Currently, the architecture looks like this:

• default.toml (file inherited from Handwrite)
  • most default glyphs
  • cli.py writes custom words to specific indices in glyphs-fancy, in a font-specific JSON copy of default.toml
  • sheettopng uses the grid cell number as an index into default.toml's glyphs-fancy, to assign each grid cell a name, before saving each PNG
  • svgtottf:add_ligatures goes through glyphs-fancy, and creates a ligature for each entry with a ligature field
    • also adds them to glyphs_with_ligatures, for cartouching
    • also hard-codes the list cartoucheable_non_words
  • svgtottf:add_glyphs goes through glyphs-fancy, and adds each character to the font file, using the codepoint field if present
  • codepoints for UCSUR words not included on the template
  • mapping of ASCII special characters used in custom ligatures, to legal glyph names for those characters
  • copy existing glyphs to create ASCII codepoints
  • add ligature for space space
  • omit certain glyphs (cartouche, ijklmpstuw vertically, te/to, pixel fonts) from having their scan areas centered
    • note that the vector glyphs themselves are actually centered later
  • add characters for zero-width space and ideographic space
  • add blank full- and zero-width glyphs for special characters
• cli.py
  • positions of custom word slots
  • open question: how should i associate the custom words string with the default page? is it just a first-page-only feature?
• sheettopng.py
  • positions of custom word slots
  • shift cartouche scan area
  • generate PNG for the inner part of the cartouche
• add_ligatures.py
• create_toml_html.py
  • print default glyphs on preview webpage
  • print custom glyphs on preview webpage, passed in directly from cli.py
• svgtottf.py (including _ffpython)

This complexity prevents us from adding these features.

I think a better architecture would look like this:

• default-sheet.toml:
  • the physical position and behaviors of the 180 glyphs on the 1st sheet
  • the generated cartouche middle
• default-font-settings.toml:
  • glyph names necessary for custom ligatures (letters and numbers)
  • fallback glyphs for punctuation used in sitelen Lasina prose, such as ,;!?
  • fallback glyphs for ligatures used in unsupported SP features, such as (){}*",+&
• optional further sheet .toml files, specified on the command line alongside extra sheet images!
