;;; Commentary:

;; This file adds support for `units.sty'.

;;; Code:

(require 'tex)

;; Silence the compiler:
(declare-function font-latex-add-keywords
                  "font-latex"
                  (keywords class))

(TeX-add-style-hook
 "units"
 (lambda ()
   (TeX-add-symbols
    '("unit" [ "Value" ] "Unit")
    '("unitfrac" [ "Value" ] "Unit in numerator" "Unit in denominator"))
   ;; units.sty requires the package nicefrac.sty, thus we enable the
   ;; macros of nicefrac.sty, too
   (TeX-run-style-hooks "nicefrac")
   ;; Fontification
   (when (and (featurep 'font-latex)
              (eq TeX-install-font-lock 'font-latex-setup))
     (font-latex-add-keywords '(("unit" "[{") ("unitfrac" "[{{")) 'textual)))
 TeX-dialect)

(defvar LaTeX-units-package-options '("tight" "loose")
  "Package options for the units package.")
