156103 - View selection source

Status: RESOLVED DUPLICATE of bug 28809

(Core Graveyard :: View Source, enhancement)

Description

[Robert Accettura [:raccettura]]

When I select some text on a page, then right click to "View Selection Source"
it simply displays the line that contains the code.  

Is it possible to maybe display the entire source of the page, and highlight the
portion of text selected in the page?  I don't know why someone would want only
the source they selected.  I would think most like myself would want it for a
quick way to reference through long html pages and go right to a particular section.

At the very least, if the text is deselected, the rest of the HTML should come
into view, leaving the current location of the formerly selected text in view as
reference.

I just think the feature would be much more useful as such.

In fact, the view source just shows the parent node of the selection, so the
enhancement would be something as "easy" as go up in the tree to the root node
instead of using the parent of the selection.

As I don't find a dup and I think it's a good idea I'm confirming it.

It is kept small for speed reason (see bug 28809). The view-source is
*constructed* on the fly from the DOM of the active document. If the entire
document was to be re-constructed this way everytime a selection is displayed,
it might make the feature to look sluggish, especially for large documents.

Note that it remains possible to select a bigger portion to view a wider context.

Why not a prefs option to either keep as is, or show the entire source with the 
selected component highlighted?

Ah, another pref, that's a question for mpt to ponder about...

(But FYI, the code can already support either option with minimun changes)
