Uses a less destructive method (the same that Spacemacs uses) than the
one introduced in 13cee68, by introducing MODE-local-vars-hook hooks,
which run after local vars have been initialized.
The old method was to call `hack-local-variables` *before* mode hooks
run, however, this causes variables set by modes to have higher
precedence than local vars, which is unacceptable.
Also moved intero-mode & dante-mode to haskell-mode-local-vars-hook
Initialize it globally and turn it off where needed, instead of enabling
it on demand. Also fixes void-function: flycheck-mode errors when
:feature syntax-checker is disabled. This is experimental.
Indirectly fixes#710
It wasn't working in the first haskell buffer because of a race
condition. Intero was loading too late to register lookup handlers for
haskell-mode (for the first buffer).
By setting it to intero-mode, it is registered in time for intero-mode's
activation.
This is a breaking change! Update your :popup settings. Old ones will
throw errors!
Doom's new popup management system casts off its shackles (hur hur) and
replaces them with the monster that is `display-buffer-alist`, and
window parameters.
However, this is highly experimental! Expect edge cases. Particularly
with org-mode and magit (or anything that does its own window
management).
Relevant to #261, #263, #325
