* Description
This layer provides spell checking using [[http://www-sop.inria.fr/members/Manuel.Serrano/flyspell/flyspell.html][Flyspell]] and =[[https://github.com/nschum/auto-dictionary-mode][auto-dictionary-mode]]=.
* Install
** Layer
To use this configuration layer add it to your =~/.spacemacs=
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers '(spell-checking))
#+END_SRC
** Spell Checker Configuration
The built-in Emacs variable that controls which external spell-checking program
is used is =ispell-program-name=, which can be set in your
=dotspacemacs/user-init= function if you do not like the default. It will give
priority to =aspell= if it is installed on your system. Another important
variable to be aware of is =ispell-dictionary= which will control the default
dictionary used by =ispell-program-name= (instead of using this variable you can
also use the key binding ~SPC S d~).
** Disabling by default
By default, =spell-checking= is enabled in all available major modes and may be
toggled off with ~SPC t S~. You can default this to off by setting the variable
=spell-checking-enable-by-default= to =nil=:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers
'((spell-checking :variables spell-checking-enable-by-default nil)))
#+END_SRC
** Enabling auto-dictionary-mode
=auto-dictionary-mode= tries to detect the current language from the buffer
content, and activate the corresponding dictionary. You can enable it by setting
the variable =spell-checking-enable-auto-dictionary= to something other than
=nil=:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers
'((spell-checking :variables spell-checking-enable-auto-dictionary t)))
#+END_SRC
Some people encountered bugs with =auto-dictionary-mode=, especially in *daemon
mode* where new =emacsclient= open directly freezed. If so, no other workaround
have been found yet than disabling =auto-dictionary-mode= completely.
Not all languages are supported by =auto-dictionary-list=. The supported
languages are listed in the =adict-language-list= variable, that can be checked
with =spacemacs/describe-variable=. For convenience, here is the list of
currently supported language:
