mozrepl

There used to be MozREPL: https://github.com/bard/mozrepl but it never made it over the webextension/quantum changeover. I haven't yet found a replacement, although I haven't been looking very hard recently.

>Embed mozrepl https://github.com/bard/mozrepl/wiki or something simular. I'd like network based access (restricted to a socket or localhost by default) to the innards of the browser. Mozrepl works, but has proven fragile. I've had to make several updates to keep it working with the latest Firefox nightlies. That looks really interesting. I just tried out swank-js and it worked for simple javascript, but it didn't work with dojo (going to debug that and see if there isn't an easy solution). How does this work with more complex javascript? Does it work with libraries like jquery or dojo? Does the link you gave have your fixes? I will probably give this a try tomorrow, thanks for the link!

Mozrepl works, but has proven fragile. I've had to make several updates to keep it working with the latest Firefox nightlies. I've currently got mozrepl hooked to emacs so when I save a js, coffeescript, or css/scss file it live updates the page. This makes development so much quicker. I know there's several other methods of achieving this, but to be clear I'm not talking about reloading the page, I'm talking about updating the backbone model of type Foo to have a new definition when I save model/Foo.coffee. I can also see this being useful for acceptance testing. I'd imagine that the Selenium project would also be interested.

I spent the weekend playing with ClojureScript One, and this line really stood out for me: "Moreover, JS is really fast to write and test. Write – save – refresh[2]; it’s an absurdly fast dev cycle that lets me iterate on questionable portions of the code much faster than any environment I’ve worked in." With ClojureScript and Emacs, this cycle is replaced with "write - C-x C-e" (For the unfamiliar, Ctrl-x Ctrl-e sends the Lisp form immediately before the cursor to the compiler, and sends the resulting JavaScript to the browser for execution. It lets you evaluate bits of code directly from your editing buffer. It's the classic Lisp and Emacs set up and it's fantastic.) Is there no browser-connected REPL for regular-ole JavaScript? I don't know the details of the ClojureScript implementation, but I would imagine you could hack it up to use

MozRepl can give you a JS repl in emacs tied into the browser...no refresh required: https://github.com/bard/mozrepl/wiki

http://github.com/bard/mozrepl/wikis/home is a cool little project I've been watching on github; it to provides emacs integration, now it's just a matter of learning emacs. ;_; Here's a neat screencast of it in action: http://www.youtube.com/watch?v=v78HRi-J2ek
