Changelog – KaTeX → MathJax Converter Plugin

Fixes

• Prevent inline $…$ wrapping inside display $$…$$ blocks

  • Re-ordered processing in processMath:
  1. Wrap math-dominant lines (wrapBareMathLinesOutside) first.
  2. Only then apply inline conversions (convertInlineDelims, wrapInlineBareLatex) outside display spans.
  • Added guard in isMathLine to skip any line that already contains a $.

Features

• New settings toggles in the settings tab:

  • Plain parentheses ( … ) as delimiters → converts (x^2+1) → $x^2+1$ when LaTeX-like.

  • Plain brackets [ … ] as delimiters → same logic for [a,b].

  • Convert bare inline LaTeX → detects and wraps tokens like:

  • 90^\circ → $90^{\circ}$

  • \sqrt{…} → $\sqrt{…}$

  • \frac{…}{…} → $\frac{…}{…}$

  • simple subscripts/superscripts like x_i, y^2.

  • Wrap single math lines → isolated equations like a^2 + b^2 = c^2 become:

  $$
  a^2 + b^2 = c^2
  $$

  • Wrap matrix/align environments → wraps bare \begin{bmatrix} … \end{bmatrix} into display math.

Enhancements

• Comprehensive LaTeX-like detector (isLatexLike)
  Expanded to cover:

  • Greek letters
  • Calculus operators (\partial, \nabla, \sum, \int)
  • Vector/matrix environments
  • Common functions (sin, cos, log, exp, etc.)
  • Unicode math symbols (≤, ≥, ∞, ∇, etc.)

• Better guards for parentheses/brackets

  • Avoids converting (a) list markers or [link](url) syntax.
  • Uses local context (contextIsMathy) to only treat (n) etc. as math in math-heavy prose.
