Version 0.1.7 (2026-02-01)

  • Generate expressions in code form (i.e., generic statements and Rust).
  • Update KaTeX.

Version 0.1.6 (2025-11-05)

  • Fix KaTeX, maybe?
  • Rename Graph to Tree.
  • Fix text form for "{:-}".

Version 0.1.5 (2025-11-04)

  • Add DOT form (i.e., text/vnd.graphviz) via Octal trait.
  • Add alternative symbols labelled after basis blades ("{:#}").
  • Implement factorization of pinned symbols, GCD coefficients, and predominant sign.
    • Expand ("{:+}") or reduce (i.e., factorized) ("{}").
    • Factor predominant sign ("{:-}").
  • Eliminate orthonormalization conditions from expressions using reflection/projection operator.
  • Evaluate symbols as rationals.
  • Count operations (i.e., multiplications and additions).
  • Fix KaTeX rendering on large pages.

Version 0.1.4 (2025-10-16)

  • Update KaTeX.
  • Explore 6D/7D PGA.
  • Assert entities have unique symbols and exactly one per basis blade fixing 4D PGA.
  • Introduce Symbol::alt() to extend symbol space.
  • Rechoose basis blades following recipe. After a refactoring, they can be genrated this way.
  • Refactor rational numbers without dependency and find their GCD/LCM.
  • Refactor symbol without dependency.
  • Swap case without dependency.
  • Always export format_eq! by using non-pretty fallback.
  • Let format_eq! omit unit coefficient for more compact text form.
  • Introduce {:+} for not omitting unit coefficient.
  • Fix invalid coefficient omission.
  • Fix typo and link.
  • Construct Cayley table with pre-allocations only.

Version 0.1.3 (2025-09-18)

  • Add projection operator. Supports rejection, i.e., projecting lower- onto higher-grade blade.
  • Use Unicode combining diacritical marks instead of ~/L/R.
  • Define 6D/7D PGA blades.

Version 0.1.2 (2025-09-07)

  • Generate constructor methods of basis blades with compile-time blocks.
  • Distinguish bias/weight (W/w) from scalar/pseudoscalar (v/V) and relabel norm.
  • Distinguish motors.
  • Add more examples.
  • Add polarity operator.
  • Fix bugs, typos, and improve documentation.
  • Explore 4D/5D PGA.

Version 0.1.1 (2025-09-02)

  • Fix KaTeX documentation.

Version 0.1.0 (2025-09-02)

  • Implement symbolic reduction of multivector expressions.
  • Implement generation of expressions in text form.
  • Define the metric-agnostic basis (i.e., elliptic, parabolic, hyperbolic) and the multivector entities of the projective geometric algebra (PGA) for dimensions N < 6. Assert the Cayley tables in unit tests.

Version 0.0.0 (2021-06-27)

  • Reserve name.
