I have written an HTML document to help others use Vim as a basic text processing application. It discusses how to integrate spell checking, dictionary, and thesaurus applications. It also talks about wrapping lines, indentation, justification, and the vim settings that effect the behavior of these operations. The document can be found at:
Everything has been tested with UNIX, Linux, Windows, and Windows with Cygwin patforms.
I used above successfully
If you happen to use Aspell on a Unix "shell" eg MKS on Win32 you may want
:set shellslash (unix forward slash)
Also if you map the full path to aspell in your map eg c:/vim/aspell/aspell.exe you wont need an environment variable
map <Leader>s <Esc>:!c:/vim/aspell/aspell.exe -c --dont-backup %<CR>:e! %<CR><CR> or map <Leader>s <Esc>:!c:\vim\aspell\aspell.exe -c --dont-backup %<CR>:e! %<CR><CR>
People love to put spaces in their file names in MS Windows these days. I used the aspell lines provided with the full path as noted by zzapper, david at tvis dot co dot uk. At first his example did not work because I was using someone's file with a space in it for testing. I then changed
map <Leader>s <Esc>:!c:\vim\aspell\aspell.exe -c --dont-backup %<CR>:e! %<CR><CR> to map <Leader>s <Esc>:!c:\vim\aspell\aspell.exe -c --dont-backup "%"<CR>:e! "%"<CR><CR>
Please note the quotes around the percent sign, "%". Both the tip and David's note are very effective. You'd want to do something similar on Linux too. Especially if you are serving up files with Samba. See http://www.samba.org
Read Toggle_spellcheck_with_function_keys to learn how to enable and disable spellchek for several languages with function keys or <Leader>s only when you need it.
