ttf-to-textfont will convert a TrueType font into a 'textfont' file, which is a simple text file describing a bitmapped font.

textfont-to-octo will convert the textfont file into Octo assembly code.

An intermediate file is used so that the font can be hand edited before the final conversion.

This is a hacked-up work in progress. To get full functionality, you will need to edit the source code. textfont-to-octo is especially rough. Currently limited to 8x8px or smaller glyphs.

Many improvements could be made:

• Handling of larger glyphs, using multiple sprite ops and/or 16-bit SuperChip sprites
• A sparse mode with a glyph location lookup table to avoid lots of 0s
• A fixed width mode without a width table
• Variable height glyphs
• Optional output of sample test code
• Additional functions, such as drawing a string
• Advanced kerning rules
• Optional guards for out-of-bounds inputs
• Better handling of vertical alignment and the font baseline. Clipping the glyphs with a bounding box is not helping with this.
• Use of register aliases
