Is it possible to view Clojure function documentation in Emacs? Namely, can I configure Emacs to lookup Clojure functions under the cursor?
I'm using clojure-mode and SLIME. Oddly, I can't even use apropos or dir in SLIME's repl, although they're automatically loaded by lein repl.
Try the function slime-describe-symbol, which is usually bound to C-c C-d d.
Place the point somewhere near the function name and hit C-c, then C-d, and then d.
There's also slime-describe-function, bound to C-c C-d f, but I rarely use it, as it's less general than the aforementioned symbol-related lookup function.
To see all the documentation-related functions, press C-c C-d C-h. These bindings are not specific to Clojure; they are instead defined by SLIME, and will work as well if not better for other Lisp dialects.
C-c C-d with the documentation dispatch prefix, stopping at that point to think of which documentation I want, and then preceding with the final character. Hence, letting go of the Control key corresponds to pausing to decide.I find the combination of slime-apropos and eldoc minor mode (make sure you have swank-clojure 1.4.0 as it fixes both of those) better than the slime-describe-symbol/function commands mentioned above.
From SLIME REPL you can run (use 'clojure.repl). This will make functions like apropos and doc available
