staticintlucas / keyset-rs

A (WIP) reimplementation of pykeyset in Rust for improved performance. Eventually this aims to become the backend for pykeyset, with pykeyset becoming a thin wrapper around keyset-rs.

keyset-rs's Issues

PDF/AI generation

Add support for generating PDF (and AI) graphics

Lazy evaluation of glyphs

If someone uses a big font with potentially thousands of glyphs they are currently all loaded in.

A better solution is lazily load/parse them as needed.

Add documentation

See also #4.

Generate raster images

• PNG
• Other formats?

no_std support

• Determine if this is worth it
  • PyO3 (and therefore pykeyset) require std regardless
• Modify/replace/fork dependencies without no_std support
• Replace HashMap with hashbrown/BTreeMap/IndexMap
• Iron out any other wrinkles

Proper public API design

Figure out how best to support icons

The old pure-Python pykeyset had support for icons in it's own XML format but I don't think that was a good approach.

With current functionality it's possible to add icons as glyphs by editing the font, but that's not ideal. So I see a couple of options:

1. Allow importing of SVG icons
   • This probably requires a reasonably full featured SVG parser, which is a lot of work
   • No standard way to specify alignment w.r.t. legend text
2. Allow importing of a subset of SVG or just a path
   • Shouldn't be too difficult to implement
   • What is the recommended way of creating these files? Is there a tool that can convert/extract a path from an SVG created in e.g. Inkscape?
   • No standard way to specify alignment w.r.t. legend text
3. Allow multiple fonts, so that text and icon fonts can be loaded separately
   • Easy to implement
   • Creating fonts is nowhere near as user-friendly
   • Can't easily control font size and icon size independently
   • Can't easily be extended in future to allow e.g. full colour icons (unless we add support for the SVG font table, which brings us back to 1.)

Move KLE code to separate crate?
