1263123 - Devtools: Debugger should automatically print expanded variable values next to source code

Status: RESOLVED DUPLICATE of bug 1254658

(DevTools :: Debugger, defect, P3)

Description

[Jens]

Attachment: Chrome prints expanded variables in debugger

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160315153207

Steps to reproduce:

1. Open Debugger panel in devtools
2. Set breakpoint somewhere



Expected results:

I would like to have the variables automatically expanded to its values like Chrome does, see screenshot. This really eases debugging since I can easily see parameters passed to a function, or what the value of surrounding variables are. 

This is especially helpful if I do not know yet which variable might cause the error. Currently I can only investigate specific variable by selecting them using the "Variables" panel at the right side or use the mouseover popup. Both are great, but require more time and a deeper knowledgde of which variable you are interested in already which is - as said - not always known beforehand when debugging.

* The printed/expanded variables should be mouse hoverable and show the variables popup then
* it should also work for minified sources that are auto-prettified (Chrome doesn't do this atm) or prettified using a source map
