Trying to convert arbitrary strings to Clojure objects via read-string is rather dangerous – read-string can execute arbitrary code (if the string happens to look like a tagged literal).
Aside from that, read-string is only going to read the first expression from the string: (read-string “42 13”) ;=> 42 – the “ 13” portion is just ignored And anything like a file path is going to give you a read failure as well: (read-string "/path/to/file") ;=> java.lang.RuntimeException: Invalid token: /path/to/file or if it’s a Windows path with a drive specifier: (read-string "c\\:/path/to/file") ;=> c – and the rest of the string is ignored Sean Corfield -- (970) FOR-SEAN -- (904) 302-SEAN An Architect's View -- http://corfield.org/ "If you're not annoying somebody, you're not really alive." -- Margaret Atwood On 4/14/17, 2:39 PM, "[email protected] on behalf of [email protected]" <[email protected] on behalf of [email protected]> wrote: Hi I am trying to compare two eclipse preferences files with a piece of code I picked from internet Some of the values in the file are version numbers and clojure is throwing number format error.
