in reply to Web based perl REPL

Looks pretty cool, one problem I noticed was in your handling of \n in the P of the loop. I tried this:

> print $_, "\n" for (1 .. 10)
and it only printed '1', and nothing else. I suspect you need to read in all the lines returned, then join it with a HTML br tag or something.

    You are very correct, I'm afraid it's been a long standing bug. My essential problem is I have no real way of telling when the output has ended, so at the moment I just read the first line and return that.

    Also while I'm listing bugs, it doesn't handle STDERR very well. Or at all. =[
      Perhaps you could append a ;print "END_OF_OUTPUT\n"; to the code that was sent in and then read until that. I'm not sure how your loop works, but you could probably also append a value to "END_OF_OUTPUT" that doesn't occur within the code.
