;;; Commentary: ;; M-x tex-math-preview previews TeX math expressions. Put point in a TeX, ;; LaTeX, Texinfo, Wikipedia or DBTexMath math expression and M-x ;; tex-math-preview shows either an image or TeX error messages. ;; ;; `tex-mode' has its own far more substantial buffer and region previewing, ;; but tex-math-preview is intentionally simpler and is geared towards ;; unsophisticated TeX users. ;; ;; This started for Texinfo as a way to check how "@tex $$ $$ @end tex" ;; forms come out, and @math{} after it became TeX-ified. The LaTeX bits ;; haven't had quite as much use, and there might be better ways to choose ;; between TeX or LaTeX. See also latex-math-preview.el for an adaption ;; designed specifically for that, http://www.emacswiki.org/LaTeXMathPreview ;; ;; See also latex-math-symbol.el (which comes with mu-cite) for just turning ;; TeX character forms such as \alpha into Unicode characters.
