Looks like something in re-matches is printing the second argument, but without a terminating newline. A subsequent print, such as of "nil\n" or "(1 2)\n", by the REPL evaluator, with a newline, then completes the line and flushes the output buffer. There seem to be three separate errors here, two of them in re-matches: 1. The one case where you slipped in an extra close parenthesis, which is what caused the exceptions. 2. The peculiar printing (without flushing) of the second argument by re-matches. (I don't know where it's going with some of the different REPLs but perhaps those ones maintain a different output stream for *out* and for REPL evaluation result printing.) 3. The regexp *should* match "foo.gif\n" from the looks of it, but seems not to be doing so. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
