This section describes the commands to check the spelling of a single word or of a portion of a buffer. These commands only work if the spelling checker program Aspell, Ispell or Hunspell is installed. Aspell, Ispell or Hunspell are not part of Emacs, but one or the other is usually installed in GNU/Linux and other free operating systems. See.
To check the spelling of the word around or before point, and
optionally correct it as well, type M-$ (
If a region is active, M-$ checks the spelling of all words
within the region. See Mark. (When Transient Mark mode is off,
M-$ always acts on the word around or before point, ignoring the
region. See Persistent Mark.)
Similarly, the command M-x ispell performs spell-checking in the region if one is active, or in the entire buffer otherwise. The commands M-x ispell-buffer and M-x ispell-region explicitly perform spell-checking on the entire buffer or the region respectively. To check spelling in an email message you are writing, use M-x ispell-message; that command checks the whole buffer, except for material that is indented or appears to be cited from other messages. See Sending Mail.
When one of these commands encounters what appears to be an incorrect word, it asks you what to do. It usually displays a list of numbered “near-misses”—words that are close to the incorrect word. Then you must type a single-character response. Here are the valid responses:
query-replaceso you can replace it elsewhere in the buffer if you wish. (The replacements will be rescanned for more spelling errors.)
In Text mode and related modes, the command M-<TAB>
ispell-complete-word) shows a list of completions based on
spelling correction. Insert the beginning of a word, and then type
M-<TAB>; the command displays a completion list window. (If
your window manager intercepts M-<TAB>, type <ESC>
<TAB> or C-M-i.) To choose one of the completions listed,
click Mouse-2 or Mouse-1 fast on it, or move the cursor
there in the completions window and type <RET>. See Text Mode.
Once started, the Aspell or Ispell or Hunspell subprocess continues to run, waiting for something to do, so that subsequent spell checking commands complete more quickly. If you want to get rid of the process, use M-x ispell-kill-ispell. This is not usually necessary, since the process uses no time except when you do spelling correction.
Ispell, Aspell and Hunspell use two dictionaries together for spell checking:
the standard dictionary and your private dictionary. The standard
dictionary is specified by
ispell-dictionary. If both are
the default dictionary is selected. The command
M-x ispell-change-dictionary sets the standard dictionary for
the buffer and then restarts the subprocess, so that it will use a
different standard dictionary. Personal dictionary is specified by
nil, default value is
ispell-dictionary to select a specific default
dictionary for all your documents. Set variable
ispell-local-dictionary in the local variables section to
select a specific dictionary for a given document.
A separate dictionary is used for word completion. The variable
ispell-complete-word-dict specifies the file name of this
dictionary. The completion dictionary must be different because it
cannot use root and affix information. For some languages, there
is a spell checking dictionary but no word completion dictionary.
Flyspell mode is a fully-automatic way to check spelling as you edit
in Emacs. It operates by checking words as you change or insert them.
When it finds a word that it does not recognize, it highlights that
word. This does not interfere with your editing, but when you see the
highlighted word, you can move to it and fix it. Type M-x
flyspell-mode to enable or disable this mode in the current buffer.
flyspell-mode in all text mode buffers, add
When Flyspell mode highlights a word as misspelled, you can click on it with Mouse-2 to display a menu of possible corrections and actions. You can also correct the word by editing it manually in any way you like.
Flyspell Prog mode works just like ordinary Flyspell mode, except that it only checks words in comments and string constants. This feature is useful for editing programs. Type M-x flyspell-prog-mode to enable or disable this mode in the current buffer.blog comments powered by Disqus
