Is there a clojure IDE can help autocomplete Java object method?

Question

Is there a clojure IDE that can help autocomplete a Java object method?

For example:

(def my-temp-file (java.io.File/createTempFile "filename" ".txt"))

then i want to input:

(.deleteOnExit my-temp-file)

how can i :

(. my-temp-file delet|"cursor here") ;; how can i get auto-complate del* methods

or

(.delet|"cursor here" my-temp-file) ;; how can i get auto-complate del* methods

...

just now, I tried intellij14.1.4 + cursive0.1.60, it's wonderful.

i tried to auto-complate from "delete" to " deleteOnExist"

Situation 1 ,This is ok:

Situation 2 ,this canot work :

How can I get the "deleteOnExist" autocomplete in Situation 2? please help

The problem with your example is that def does not automatically add the :tag metadata based on the type of its initialiser. You can see this as follows:

Connecting to local IDE...
Clojure 1.7.0
(import java.io.File)
=> java.io.File
(def temp-file (File/createTempFile "filename" ".txt"))
=> #'user/temp-file
temp-file
=> #object[java.io.File 0x6c8b97fd "/var/folders/x1/9k18lcbn4qnfs4pptm0dm8fm0000gn/T/filename8344242261832815384.txt"]
(meta #'temp-file)
=> {:line 1, :column 1, :file "NO_SOURCE_PATH", :name temp-file, :ns #object[clojure.lang.Namespace 0x548b68c5 "user"]}

So your example will work in cases like the following:

(let [temp-file (File/createTempFile "filename" ".txt")]
  (temp-file .dele|))

Where | represents the caret. It will also work if you manually add the tag to your def, like:

(def ^File temp-file (File/createTempFile "filename" ".txt"))
