* Description
|
|
This layer adds on the fly syntax checking to all supported language layers.
|
|
|
|
** Features:
|
|
- Support for automatic syntax checking with [[http://www.flycheck.org/][Flycheck]] for various language layers
|
|
- Tooltip syntax errors with =popwin=
|
|
|
|
* Install
|
|
** Layer
|
|
To use this configuration layer, add it to your =~/.spacemacs=. You will need to
|
|
add =syntax-checking= to the existing =dotspacemacs-configuration-layers= list in this
|
|
file.
|
|
|
|
As this is a support layer you will also have to install at least one supported language
|
|
layer for it to have any effect.
|
|
|
|
** Enabling/Disabling tooltips
|
|
By default tooltips are enabled and used whenever it is possible.
|
|
You can disable them by setting the variable =syntax-checking-enable-tooltips=
|
|
to =nil=:
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(setq-default dotspacemacs-configuration-layers
|
|
'((syntax-checking :variables syntax-checking-enable-tooltips nil)))
|
|
#+END_SRC
|
|
|
|
** Disabling by default
|
|
By default, syntax-checking is enabled in all available major modes (except for
|
|
=emacs-lisp-mode=) and may be toggled off with ~SPC t s~. You can default this to off
|
|
by setting the variable =syntax-checking-enable-by-default= to =nil=:
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(setq-default dotspacemacs-configuration-layers
|
|
'((syntax-checking :variables syntax-checking-enable-by-default nil)))
|
|
#+END_SRC
|
|
|
|
If you want more fine-grained control, you can configure the variable
|
|
=flycheck-global-modes= instead. Note that this variable should be manipulated
|
|
in =dotspacemacs/user-config=.
|
|
|
|
** Bitmaps
|
|
If the original flycheck fringe bitmaps are more to your liking, you can set the
|
|
variable =syntax-checking-use-original-bitmaps= to =t=:
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(setq-default dotspacemacs-configuration-layers
|
|
'((syntax-checking :variables syntax-checking-use-original-bitmaps t)))
|
|
#+END_SRC
