syl20bnr ebe4c60264 Revert "Defer packages by default using use-package-always-defer" 
This reverts commit 29c78ce841 and all other fixes
that have been made afterwards.

The motivation is that use-package is seen by many as a replacement for
`require`. Is use-package always defer the loading of packages then is breaks
this use case, this does not respect POLA so even if it was making Spacemacs
loading faster (up to 3s faster on some startup on my machine) we just cannot
use it, it would be irresponsible. Spacemacs should be easy to use, loading
performance will come with time but it is not a priority.

Syntax Checking layer

/TakeV/spacemacs/media/commit/26095388559611a83b0c5add458197e8d6f03d9d/layers/+checkers/syntax-checking/img/flycheck.png

Description

This layer provides on the fly syntax checking using Flycheck.

Features:

  • Automatic syntax checking with Flycheck
  • 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.

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)))

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.

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)))
