The purpose of this emulation -;; is to provide a simple means for inserting accented characters -;; according to the ISO-8859-1...3 character sets. -;; -;; In `iso-accents-mode', pseudo accent characters are used to -;; introduce accented keys. The pseudo-accent characters are: -;; -;; ' (minute) -> acute accent -;; ` (backtick) -> grave accent -;; " (second) -> diaeresis -;; ^ (caret) -> circumflex -;; ~ (tilde) -> tilde over the character -;; / (slash) -> slash through the character. -;; Also: /A is A-with-ring and /E is AE ligature. -;; These two are enabled only if you set iso-accents-enable -;; to include them: -;; . (period) -> dot over the character (some languages only) -;; , (cedilla) -> cedilla under the character (some languages only) -;; -;; The action taken depends on the key that follows the pseudo accent. -;; In general: -;; -;; pseudo-accent + appropriate letter -> accented letter -;; pseudo-accent + space -> pseudo-accent (except comma and period) -;; pseudo-accent + pseudo-accent -> accent (if available) -;; pseudo-accent + other -> pseudo-accent + other -;; -;; If the pseudo-accent is followed by anything else than a -;; self-insert-command, the dead-key code is terminated, the -;; pseudo-accent inserted ‘as is’ and the bell is rung to signal this. -;; -;; Function `iso-accents-mode' can be used to enable the iso accents -;; minor mode, or disable it. - -;; If you want only some of these characters to serve as accents, -;; add a language to `iso-languages' which specifies the accent characters -;; that you want, then select the language with `iso-accents-customize'. - -;;; Code: - -(provide 'iso-acc) - -(defgroup iso-acc nil - "Minor mode providing electric accent keys." - :prefix "iso-accents-" - :group 'i18n) - -(defcustom iso-accents-insert-offset nonascii-insert-offset - "Offset added by ISO Accents mode to character codes 0200 and above." - :type 'integer - :group 'iso-acc) - -(defvar iso-languages - '(("catalan" - ;; Note this includes some extra characters used in Spanish, - ;; on the idea that someone who uses Catalan is likely to use Spanish - ;; as well. - (?'
