preflight: ja relation symbols by yasumorishima · Pull Request #18 · yasumorishima/MathCAT

yasumorishima · 2026-09-05T07:33:48Z

Preflight only (CI + CodeRabbit).

Summary by CodeRabbit

Improvements
- Updated Japanese speech output for comparison, inequality, approximation, and set-membership symbols.
- Standardized spoken forms for “greater than,” “less than or equal to,” “not equal,” and related mathematical notation.
- Improved Japanese ClearSpeak and SimpleSpeak coverage for these symbols, including membership in number sets.

`unicode.yaml` puts the relation word between the two operands, so the word has to work there. Several did not. - `>` said より大きい. より needs its comparand in front of it, so "x はより大きい 5" parses as "x is a bigger 5". It also did not match the 小なり already used for `<` in the same file. Yamaguchi, Kawane & Sawazaki (1996) give the pair 小なり / 大なり, and 小なり・オア・イコール for `≤` (the ・ is only a word separator and is not read), so `≥` follows as 大なり・オア・イコール. - `≠` said 等しくない, a predicate with the same problem. The source gives ノット・イコール, which pairs with the イコール already used for `=`. - `∈` and `∊` said 要素の for "element of". の attaches backwards: 要素の A is "A of an element". The source gives 要素オブ, the same borrowed オブ this translation already uses for "of" elsewhere. The two rules also disagreed with each other -- ∈ said 属する where ∊ said 要素の, for the same English. - The ClearSpeak "In" option said 中へ, which is "into", a direction of motion. The source's reading for "in" is the borrowed イン. - `∾` said 最も肯定的な, "most affirmative"; en is "most positive" in the numeric sense, so 最も正の. Left alone: the negative set relations (∉ ⊄ ⊅) and the subset family (⊂ ⊃ ⊆ ⊇). The source gives 部分集合オブ for ⊂ but nothing for the superset or the negated forms, and I did not want to change half a family.

📝 Walkthrough

Walkthrough

Japanese Unicode speech rules now use revised readings for comparison, inequality, approximation, and element-membership symbols. Japanese tests cover the updated SimpleSpeak and ClearSpeak output.

Changes

Japanese speech rules

Layer / File(s)	Summary
Update Japanese symbol readings `Rules/Languages/ja/unicode.yaml`, `tests/Languages/ja/ja.rs`	Comparison, inequality, approximation, and membership symbols use revised Japanese readings. Tests validate the updated SimpleSpeak and ClearSpeak results, including both `∈` and `∊`.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to f70bf

Japanese symbol speech updates change ClearSpeak set-membership wording. The inside-set In behavior for both membership symbols is not covered by tests, so a regression could affect Japanese users without being detected.
