MODES can be one major mode, or a list thereof.
DOCSETS can be strings, each representing a dash docset, or a vector with the
structure [DOCSET FORM]. If FORM evaluates to nil, the DOCSET is omitted. If it
is non-nil, (format DOCSET FORM) is used as the docset.
The first element in DOCSETS can be :add or :remove, making it easy for users to
add to or remove default docsets from modes.
DOCSETS can also contain sublists, which will be flattened.

[\"React\" (eq major-mode 'rjsx-mode)]
[\"TypeScript\" (bound-and-true-p tide-mode)])

(defun set-lookup-handlers! (modes &rest plist)
"Define jump handlers for major or minor MODES.
A handler is either an interactive command that changes the current buffer
and/or location of the cursor, or a function that takes one argument: the
identifier being looked up, and returns either nil (failed to find it), t
(succeeded at changing the buffer/moving the cursor), or 'deferred (assume this
handler has succeeded, but expect changes not to be visible yet).
There are several kinds of handlers, which can be defined with the following
properties:
:definition FN
Run when jumping to a symbol's definition. Used by `+lookup/definition'.
:references FN
Run when looking for usage references of a symbol in the current project. Used
by `+lookup/references'.
:documentation FN
Run when looking up documentation for a symbol. Used by
`+lookup/documentation'.
:file FN
Run when looking up the file for a symbol/string. Typically a file path. Used
by `+lookup/file'.
:xref-backend FN
Defines an xref backend for a major-mode. A :definition and :references
handler isn't necessary with a :xref-backend, but will have higher precedence
if they exist.
:async BOOL
Indicates that *all* supplied FNs are asynchronous. Note: lookups will not try
any handlers after async ones, due to their nature. To get around this, you
must write a specialized wrapper to await the async response, or use a
different heuristic to determine, ahead of time, whether the async call will
succeed or not.
If you only want to specify one FN is async, declare it inline instead:
(set-lookup-handlers! 'rust-mode
:definition '(racer-find-definition :async t))
Handlers can either be interactive or non-interactive. Non-interactive handlers
must take one argument: the identifier being looked up. This function must
change the current buffer or window or return non-nil when it succeeds.
If it doesn't change the current buffer, or it returns nil, the lookup module
will fall back to the next handler in `+lookup-definition-functions',
`+lookup-references-functions', `+lookup-file-functions' or
`+lookup-documentation-functions'.
Consecutive `set-lookup-handlers!' calls will overwrite previously defined
handlers for MODES. If used on minor modes, they are stacked onto handlers
defined for other minor modes or the major mode it's activated in.
This can be passed nil as its second argument to unset handlers for MODES. e.g.
(set-lookup-handlers! 'python-mode nil)
