1096339 - devtools console should support multiline string entry (es6 backtick string template)

Status: RESOLVED DUPLICATE of bug 1243851

(DevTools :: Console, defect)

Description

[Gregg Lind (Fx Strategy and Insights - Shield - Heartbeat )]

To reproduce:

devtools console:

```

let a = `start of a valid es6 string template string  [ENTER key]
```

Gives:

>>> SyntaxError: unterminated string literal


Expected:  string continuation prompt change.  


Observed:
1.  Scratchpad works fine.
2.  One line backtick strings work fine.


Maybe:  resource://gre/modules/devtools/dbg-client.jsm needs to know about 'enter'

Solutions:

1.  Shift return.  Works currently.  (http://mxr.mozilla.org/mozilla-central/source/browser/devtools/webconsole/webconsole.js#3997)
2.  Mod keyboard handler to do a partial parse to see if one is inside a potentially valid multiline input situation.  Support continuation lines with new prompt etc.  (http://mxr.mozilla.org/mozilla-central/source/browser/devtools/webconsole/webconsole.js#4018)
3.  Quick hack:  Mention the 'shift' trick in a little linked [?] after the 'Syntax Error: <whatever>' message.  That should link / hover to either an explanation of the syntax error, and a mention of the multiline trick.

(1) I should have thought of, but didn't.  Is that my fault?
(2) seems rightest / nicer to me, if the web-console is meant to be used as a cli.
(3) New / different UI problems.  

Thanks!
