Bug 86621 – Web Inspector: Copy ... actions in the context menu don't work in the remote debugging mode.

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

[Mikhail Naganov]

Programmatic access to clipboard is disabled by default.

For Chrome, this can be solved by installing a simple extension like this one: http://pastebin.com/kDxUacJd

We also need to support copying in InspectorFrontendHostStub.

You don't seem to have added a corresponding localizedStrings.js entry for the message.

We use double-quotes around strings in the frontend.

We don't use braces around one-line blocks

Missing "the"? "...install the \"Chrome....."

Sorry, I was thinking they need to be symmetrical for both if branches. Removed.

I will add strings to localizedStrings once we agree on wording.

Since this code is in WebCore, it probably shouldn't be referring to specific products (in this case, Chrome)?

Why do you override this document's copy?

This code should be in WebKit/chromium/src/js/DevTools.js. Who is going to own this extension? Could it be more generic (i.e. "Clipboard access enabler"?) Or we could combine it with the Chrome extension used for filesystem persistence. I would not want to see a separate "Chrome Developer Tools Front-end" as an extension.

We need to get the Event instance passed to the copy command handler in order to set clipboardData. I've changed the code insert FrontendHost's action after the event has been processed by the default documentCopy handler.

Moved platform-specific code to DevTools.js

The extension (in fact, this is a simple Web App) specifies the starting URL (localhost:9222), adds clipboard access permissions, and specifies the frontend hosting URL as the App's URL. I've posted a link to the sample already, have you seen it? http://pastebin.com/kDxUacJd

Do you already have the extension used for filesystem persistence? Can you please point me to it?

You can only use event object while it is being dispatched. Storing it is not right.

Nope, now that I've seen it, name slearly looks wrong ("Chrome Developer Tools Frontend"). You probably want to point to a wiki describing how to enable copy / paste or something.

I still don't understand what is happening here...

{ on the next line. You should not declare top-level functions.

You need to install Chrome extension that allows clipboard access for this page.

What do you mean by "this"? The bracket is a closing for the one in the beginning of the file: "if (!window.InspectorFrontendHost) {". It's the highlighting that is a bit misguiding.
