--port is broken in 0.12

Looks like the require changes broke it.

I can help with this.

as per Slack conversation the code for this lives:
app/Command/REPL.hs and src/Language/PureScript/Interactive*

unsure what the require changes were though.

edit:

I think there's a require shim somewhere in the code that the websocket psci version sends to the browser that probably can't handle the added .js

It calls bundle https://github.com/purescript/purescript/blob/master/app/Command/REPL.hs#L122 which without looking into it seems odd as that presumably works for standalone bundle
If I was looking at this 1st step would be to repro and find out what's going wrong specifically before looking at code.

What's the correct way to debug this?
What are the correct steps to build and then call the newly built purs instead of the one installed on my system?

I'm also looking at the repl tests to see if I can replicate this there.

Thanks!

EDIT:
If I got this right, the problem is in this generated code:

    var replaced = js.replace(/require\("[^"]*"\)/g, function(s) {
        return "PSCI['" + s.substring(12, s.length - 2) + "']";
    });

which leaves a trailing /index.js for each required module.
A very crude test in chrome done by modifying the 2 into an 11 removes all errors from the repl.

I'm not sure how the interaction between the repl and the browser is supposed to work though. So I'm not sure if this actually fixes the issue (obviously changing the code in chrome is not a real fix :D)

@dariooddenino thanks for this! In case you didn't work it out, for building and running a version of purs from a local working copy, I'd recommend doing stack build --fast to build it, and then stack exec bash to put yourself into a new shell session with the newly built purs at the front of your PATH.
