Consecutive calls to set-lookup-handlers! would redefine *all* lookup
handlers, unsetting unspecified ones, so you were forced to redefine all
handlers, even if you only wanted to change one. No more. Its side
effects are now additive.
Also adds :async handler support, however, due to their nature, they
cannot fall back to other handlers (there's no reliable way to detect
they worked or not).
To get around this, write a blocking wrapper around the old async method
and register it as a non-async handler.
projectile-project-root no longer returns `default-directory` if not in
a project (it returns nil). As such, doom-project-* functions (and their
uses) have been refactored.
+ doom-project-p & doom-project-root are aliases for
projectile-project-p & projectile-project-root.
+ doom-project-{p,root,name,expand} now has a DIR argument (for
consistency, since projectile-project-name and
projectile-project-expand do not).
+ The nocache parameter is no longer necessary, as projectile's caching
behavior is now more sane.
+ Removed some projectile advice/hacks that are no longer necessary.
+ Updated unit tests
You can now control exactly what lookup backends are used for the
various lookup commands (definition, references, online and file).
This allows you to disable (or add) backends by manipulating the default
value for these lists with add-hook or remove-hook:
* +lookup-definition-functions
* +lookup-references-functions
* +lookup-documentation-functions
* +lookup-file-functions
+ Uses alist variable to store config, rather than hooks
+ Added check for installed docsets in +lookup/documentation
+ Set docsets for various language modules (c-mode, c++-mode, css-mode,
scss-mode, sass-mode, web-mode, go-mode, racket-mode, emacs-lisp-mode,
js2-mode, rjsx-mode, typescript-mode, rust-mode, and php-mode)
+ Made *eww* popups for dash docsets larger
+ Renamed set-docset! => set-docsets! (set-docset! is aliased to
set-docsets!)
+ New +lookup/install-docset alias
devdocs-lookup is broken at the moment. devdocs search is still
available through +lookup/online as a provider however. This may be
reversed later, when (and if) we find a better devdocs backend.
In likely case where (bounds-of-thing-at-point 'symbol) returns nil,
cl-destructuring-bind would throw a wrong-number-of-args error we don't
care about.
After some profiling, it turns out map-put and map-delete are 5-7x
slower (more on Emacs 25) than delq, setf/alist-get and add-to-list for
small lists (under 250 items), which is exactly how I've been using
them.
The only caveat is alist-get's signature is different on Emacs 25, thus
a polyfill is necessary in core-lib.
Some xref backends have specialized thing-at-point implementations (such
as haskell's dante's xref backend), this fix uses them to fetch the
identifier at point.
+ map-delete is shorter and faster than assq-delete-all
+ map-put is simpler than the delete-then-set workflow
+ map-merge is great for merging default and user settings
