I'm not sure if this is readline specific, or windows specific, or what, but I can't seem to get 500+ character commands to work. I didn't ever run into a problem using release-basic, but I'm trying to get release-readline support for Sublime-Julia and my tests keep failing. Even when trying to split the command into new lines of < 500 characters, it still barfs. Anyone have any insight on this?

An example where I try to create an array with 259 elements; even though I pasted a full command (note both brackets []), it returns expecting additional input, and if I close with a bracket, it only returns a 253 element array.

julia> t = [3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,

Now for the really weird part: I try to paste a few lines of 500+ characters and in between returns from readline, I get the output of ls?

Seems to work for me on linux.

I've had tons of problems in the past with the REPL being unable to process large blocks of text, so I can believe this might be a platform-specific problem.

Ok, I think I've got a workaround for this. Turns out breaking it down into sub-500 chunks and then running works just fine (I was confused because it was working sometimes but sometimes doing the ls thing). The problem, as far as I can tell, seems to be when there are any tab \t characters in any chunks after the first. The presence of \t characters seems to be triggering the ls functionality somehow. As \t doesn't hold any syntactic value (right?), I just run a pass over the chunks and replace them with a space and that seems to solve it.

I'll close this as I don't know if there's really anything else that could be done.

We're going to ditch the readline repl in favor of @loladiro's pure-Julia repl in the future in any case.
