Syntax Checking layer

Table of ContentsClose


1 Description

This layer adds on the fly syntax checking to all supported language layers.

1.1 Features:

  • Support for automatic syntax checking with Flycheck for various language layers
  • Tooltip syntax errors with popwin

2 Install

2.1 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.

2.2 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:

(setq-default dotspacemacs-configuration-layers
  '((syntax-checking :variables syntax-checking-enable-tooltips nil)))

2.3 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:

(setq-default dotspacemacs-configuration-layers
  '((syntax-checking :variables syntax-checking-enable-by-default nil)))

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.

2.4 Bitmaps

If the original flycheck fringe bitmaps are more to your liking, you can set the variable syntax-checking-use-original-bitmaps to t:

(setq-default dotspacemacs-configuration-layers
  '((syntax-checking :variables syntax-checking-use-original-bitmaps t)))
