;; INSTRUCTIONS

;;   Use the variable `ispell-local-dictionary-alist' to specify
;; your own dictionaries.

;;  Depending on the mail system you use, you may want to include these:
;;  (add-hook 'news-inews-hook #'ispell-message)
;;  (add-hook 'mail-send-hook  #'ispell-message)
;;  (add-hook 'mh-before-send-letter-hook #'ispell-message)

;;   Ispell has a TeX parser and a nroff parser (the default).
;; The parsing is controlled by the variable ispell-parser.  Currently
;; it is just a "toggle" between TeX and nroff, but if more parsers are
;; added it will be updated.  See the variable description for more info.

;;   ispell-word
;;   ispell-region
;;   ispell-buffer
;;   ispell-message
;;   ispell-comments-and-strings

;;   ispell-complete-word-interior-frag
;;   ispell-change-dictionary
;;   ispell-kill-ispell
;;   ispell-pdict-save
;;   ispell-skip-region-alist

;; Commands in ispell-region:
;; Character replacement: Replace word with choice.  May query-replace.
;; ` ': Accept word this time.
;; `i': Accept word and insert into private dictionary.
;; `a': Accept word for this session.
;; `A': Accept word and place in buffer-local dictionary.
;; `r': Replace word with typed-in value.  Rechecked.
;; `R': Replace word with typed-in value.  Query-replaced in buffer.  Rechecked.
;; `?': Show these commands
;; `x': Exit spelling buffer.  Move cursor to original point.
;; `X': Exit spelling buffer.  Leaves cursor at the current point, and permits
;;      the check to be completed later.
;; `q': Quit spelling session (Kills ispell process).
;; `l': Look up typed-in replacement in alternate dictionary.  Wildcards okay.
;; `u': Like `i', but the word is lower-cased first.
;; `m': Place entered value in personal dictionary, then recheck current word.
;; `C-l': redraws screen
;; `C-r': recursive edit
;; `C-z': suspend Emacs or iconify frame

;; Buffer-Local features:
;; There are a number of buffer-local features that can be used to customize
;;  ispell for the current buffer.  This includes language dictionaries,
;;  personal dictionaries, parsing, and local word spellings.  Each of these
;;  local customizations are done either through local variables, or by
;;  including the keyword and argument(s) at the end of the buffer (usually
;;  prefixed by the comment characters).  See the end of this file for
;;  examples.  The local keywords and variables are:

;;  ispell-dictionary-keyword   language-dictionary
;;      uses local variable ispell-local-dictionary
;;  ispell-pdict-keyword        personal-dictionary
;;      uses local variable ispell-local-pdict
;;  ispell-parsing-keyword      mode-arg extended-char-arg
;;  ispell-words-keyword        any number of local word spellings

;; Region skipping:
;;  Place new regular expression definitions of regions you prefer not to
;;  spell check in `ispell-skip-region-alist'.  Mode-dependent features can
;;  be added to latex by modifying `ispell-tex-skip-alists'.
;;  `ispell-message' contains some custom skipping code for e-mail messages.

;; BUGS:
;;  Need a way to select between different character mappings without separate
;;    dictionary entries.
;;  Multi-byte characters if not defined by current dictionary may result in the
;;    evil "misalignment error" in some versions of Emacs.
;;  On some versions of Emacs, growing the minibuffer fails.
;;    see `ispell-help-in-bufferp'.
;;  Recursive edits (?C-r or ?R) inside a keyboard text replacement check (?r)
;;    can cause misalignment errors.

  "An alist of dictionaries and their associated parameters.

Each element of this list is also a list:

 (DICTIONARY-NAME CASECHARS NOT-CASECHARS OTHERCHARS MANY-OTHERCHARS-P
        ISPELL-ARGS EXTENDED-CHARACTER-MODE CHARACTER-SET)

DICTIONARY-NAME is a possible string value of variable `ispell-dictionary',
nil means the default dictionary.

CASECHARS is a regular expression of valid characters that comprise a word.

NOT-CASECHARS is the opposite regexp of CASECHARS.

OTHERCHARS is a regexp of characters in the NOT-CASECHARS set but which can be
used to construct words in some special way.  If OTHERCHARS characters follow
and precede characters from CASECHARS, they are parsed as part of a word,
otherwise they become word-breaks.  As an example in English, assume the
regular expression \"[']\" for OTHERCHARS.  Then \"they're\" and
\"Steven's\" are parsed as single words including the \"'\" character, but
\"Stevens'\" does not include the quote character as part of the word.
If you want OTHERCHARS to be empty, use the empty string.
Hint: regexp syntax requires the hyphen to be declared first here.

CASECHARS, NOT-CASECHARS, and OTHERCHARS must be unibyte strings
containing bytes of CHARACTER-SET.  In addition, if they contain
non-ASCII bytes, the regular expression must be a single
`character set' construct that doesn't specify a character range
for non-ASCII bytes.

MANY-OTHERCHARS-P is non-nil when multiple OTHERCHARS are allowed in a word.
Otherwise only a single OTHERCHARS character is allowed to be part of any
single word.

ISPELL-ARGS is a list of additional arguments passed to the ispell
subprocess.

EXTENDED-CHARACTER-MODE should be used when dictionaries are used which
have been configured in an Ispell affix file.  (For example, umlauts
can be encoded as \\\"a, a\\\", \"a, ...)  Defaults are ~tex and ~nroff
in English.  This has the same effect as the command-line `-T' option.
The buffer Major Mode controls Ispell's parsing in tex or nroff mode,
but the dictionary can control the extended character mode.
Both defaults can be overruled in a buffer-local fashion.  See
`ispell-parsing-keyword' for details on this.

CHARACTER-SET used to encode text sent to the ispell subprocess
when the language uses non-ASCII characters.

Note that with \"ispell\" as the speller, the CASECHARS and
OTHERCHARS slots of the alist should contain the same character
set as casechars and otherchars in the LANGUAGE.aff file \(e.g.,
english.aff).  Aspell and Hunspell don't have this limitation.")

That will be set in `ispell-check-version' for Hunspell >= 1.1.6 and
Aspell >= 0.60.

For Aspell, non-nil also means to try to automatically find its dictionaries.

Earlier Aspell versions do not consistently support charset encoding.  Handling
this would require some extra guessing in `ispell-aspell-find-dictionary'.")

  "Check the spelling of a mail message or news post.
Don't check spelling of message headers except the Subject field.
Don't check included messages.

To abort spell checking of a message region and send the message anyway,
use the \\`x' command.  (Any subsequent regions will be checked.)
The \\`X' command aborts sending the message so that you can edit the buffer.

To spell-check whenever a message is sent, include the appropriate lines
in your init file:
   (add-hook \\='message-send-hook #\\='ispell-message)  ;; GNUS 5
   (add-hook \\='news-inews-hook #\\='ispell-message)    ;; GNUS 4
   (add-hook \\='mail-send-hook  #\\='ispell-message)
   (add-hook \\='mh-before-send-letter-hook #\\='ispell-message)

You can bind this to the key C-c i in GNUS or mail by adding to
`news-reply-mode-hook' or `mail-mode-hook' the following lambda expression:
   (lambda () (local-set-key \"\\C-ci\" \\='ispell-message))"
