Hi!

I am trying to use spell check in emacs.

I installed aspell and needed dictionary (I use Ukrainian). Then run command
M-x ispell-change-dictionary and choose needed dictionary (Ukrainian)
But then when I run a command ispell-buffer I get message: "invalid coding
system: koi8-u"

Thanks in advance,
Oleg

What version of Emacs is that?  What does "M-x emacs-version RET"
display?

Spell Checking

[Shug Boabby]

hi there,

i realise the flyspell and spell checking .el files heavily depend upon
spell/ispell/aspell being installed on the system, but many modern GUI
libs (such as GTK+2 with GtkSpell and OS X's Aqua/Cocoa) have the
ability to add spell checking to any text-input window. can anyone see
this kind of spellchecking becoming available in GNU Emacs in the
future?

in GTK+2 it is really just a 2-liner in the source to add the support.
but of course that won't do context stuff (like not checking maths
equations in LaTeX mode) but i'm sure it could be worked around.

at the moment i have to maintain 2 dictionaries on OS X as Emacs is not
making use of the system one, its quite irritating... also, these
methods are *much* faster than flyspell.

Someone will have to volunteer to do the work of checking out these
features and figuring out if and how to integrate them with Emacs.
Until now, no one did.

On the Mac OS X Emacs list a method was shown how to use cocoAspell in 
Emacs.

IMHO, it's the context sensitive spell checker that makes emacs/ispell
so useful.  My guess is that most emacs users are writing text with
markup (code, tex, html, ...) and the ability to check the text while
ignoring the markup is critical.

I used to wonder why people's C code had so many spelling errors,
until I realized that only emacs can spell check the comments and
strings and ignore the code.

And my periodic question:

When I spell check comments and strings and the string is part of
a printf

	printf("\tHello, world\n");

I'd like the spell checker to ignore the letter after the \.
Currently, it complains that tHello is misspelled, causing many false
errors.

Can you trick it by adding backslash-character to
ispell-skip-region-alist?

(add-hook 'c-mode-hook
           (lambda ()
             (set (make-local-variable 'ispell-skip-region-alist)
                  (cons '("\\\\[abfnrtv\\'\"]") ispell-skip-region-alist))))

Works perfectly.  Thanks once again.

Could you maybe pass this on to CC-mode people?
Or does it have some negative side effect (like severe slowdown)?

absolutely! it should be trivial to add simple "check all spelling" to,
say, the GTK builds... but being able to get flyspell to switch on/off
the system spell checker for regions is something i have no experience
with on gtk or cocoa. obviously any solution would have to tie in to
the current emacs context powers, or it'd be just annoying.
