I have the following code:
(defn post [title content timestamp] (let [[innholdet tajm] [(str "<html> <head> <title>" title " :: " blog_title "</title></head> <body><h1>" title "</h1> <br/>" content "<br/><i>posted " (Date. timestamp) "</i> <br/><a href=\"" (str blog_url) "\">[main]</a> | <a href=\"" (str blog_url) "/" timestamp ".html\">[permalink]</a> </body></html>") (str timestamp".html")]] (spit tajm innholdet) ) )
I have another function that passes the header, contents, and UNIX timestamp for the post function above. blog_title and blog_url are var defined at the top of the code. I sorted the HTML for aesthetics, in the "real code" it is not. I also do
(import 'java.util.Date) (use 'clojure.string)
If I try to execute the code, I get an error
java.lang.IllegalArgumentException
If I delete (date. Timestamp), the code runs fine, but I need to have this function (Date.).
Now if in repl i do
(import 'java.util.Date)
Then define var with timestamp
(def timestamp 1278854531000) ;; Just for pushing a var into (Date.) than just the number
And then I just copy (let) in the REPL and adjust the vars in the source code to just represent different function names instead of values (since these are REPL and vars, the functions and values that are in the source code do not exist) to be as follows:
(let [[innholdet tajm] [(str "<html> <head> <title>" (str "title") " :: " (str "blog_title") "</title> </head> <body><h1>" (str "title") "</h1><br/>" (str "content") "<br/> <i>posted " (Date. timestamp) "</i><br/> <a href=\"" (str "blog_url") "\">[main]</a> | <a href=\"" (str "blog_url") "/" (str "1278854531000") ".html\">[permalink]</a></body></html>") (str "1278854531000.html")]] (println innholdet tajm))
Now REPL gives me:
<html> <head> <title>title :: blog_title</title> </head> <body> <h1>title</h1><br/>content<br/> <i>posted Sun Jul 11 15:22:11 CEST 2010</i><br/> <a href="blog_url">[main]</a> | <a href="blog_url/1278854531000.html">[permalink]</a> </body></html> 1278854531000.html nil
Again, everything has been moved so that it would be more convenient to read, in REPL everything will come out in one big line.
The problem is that I can execute the code in REPL and get the value (Date. Timestamp), and it all works, but when I execute it inside the function in my program, I get the above error. I would appreciate it if someone could tell me what I am missing here.
