;;; Commentary:
|
||
|
|
|
||
|
|
;; The ns cache is a dict of namespaces stored in the connection buffer. This
|
||
|
|
;; file offers functions to easily get information about variables from this
|
||
|
|
;; cache, given the variable's name and the file's namespace. This
|
||
|
|
;; functionality is similar to that offered by the `cider-var-info' function
|
||
|
|
;; (and others). The difference is that all functions in this file operate
|
||
|
|
;; without contacting the server (they still rely on an active connection
|
||
|
|
;; buffer, but no messages are actually exchanged).
|
||
|
|
|
||
|
|
;; For this reason, the functions here are well suited for very
|
||
|
|
;; performance-sentitive operations, such as font-locking or
|
||
|
|
;; indentation. Meanwhile, operations like code-jumping are better off
|
||
|
|
;; communicating with the middleware, just in the off chance that the cache is
|
||
|
|
;; outdated.
|
||
|
|
|
||
|
|
;; Below is a typical entry on this cache dict. Note that clojure.core symbols
|
||
|
|
;; are excluded from the refers to save space.
