So, again, I'm trying to use Clojure to rebuild a PHP site. Right now I
need the Clojure code to read the PHP session files. In the below function,
I have a println that shows me that the path points to a file that really
does exist. And yet this if() clause seems to always return false.
(defn does-session-exist? [session-id]
(let [path-to-session-file (str "/var/lib/php5/sess_" session-id)]
(println path-to-session-file)
(if (io/file path-to-session-file)
true
false)))
"io" is an alias:
(:require [clojure.string :as st]
[clojure.java.io :as io]
[clojure.data.json :as json]
[who-is-logged-in.memory_display :as who])
I look here and see that the old monolithic Clojure contrib had an "exists"
function:
http://clojuredocs.org/clojure_contrib/clojure.contrib.java-utils/file
I see this example:
(. (clojure.contrib.java-utils/file "...") exists)
I'd like to do that but I don't know how with the modern clojure.java.io.
I know I can use Java File objects, which has a similar "exists" method,
but I wonder if there is any modern Clojure equivalent?
