1825511 - Log Javascript traces to stdout with hyperlinks which can be opened in the debugger

Status: RESOLVED FIXED

(DevTools :: Framework, enhancement)

Description

[Alexandre Poirot [:ochameau]]

There is some convention in terminals to print URLs that can be clicked.
We could log link to each frame location that Firefox can interpret and open right away in the debugger.
We could log frame locations by adding a suffix to URLs @${line}:${column}.
When opening Firefox with such URL and the debugger is already opened and it knows about this location, we could open this location in the debugger.
I imagine this feature could also be used in some other context, like opening sources in the browser from VS.Code or similar.

Attachment: Bug 1825511 - [devtools] Log JavaScript traces to stdout with hyperlinks and handle them in firefox startup.

The JavaScript tracer will log special format of links, including a precise location,
by appending @${line}:${column} to each frame's source's URL.
This URL pattern is later interpreted by DevTools command line handler in order
to automatically open the source's location in the debugger.
