Chrome developer tools workspace mappings

Question

Can anyone tell me how the Chrome developer tools workspace mappings work. I believe it is only available in Canary at the moment.

I thought it is supposed to allow me to make changes to the CSS rules in the elements view and have them automatically saved to the local files as demonstrated by Paul Irish at Google IO 2013. I can't get this functionality to work.

Answer 1

It works only in canary at the moment.

EDIT: Now in Chrome (since ver 30+)

1) you need to open devtools settings panel. It has 'Workspace' section.

2) in this section you need to click on 'Add folder' item. It will show folder selection dialog.

3) After selecting a folder you will see an info bar about access rights for the folder.

4) As a result you will see two top level elements in the Source panel file selector pane. In my case it were localhost:9080 site and devtools local file system folder. At this moment you need to create a mapping between site files and your local files. You can do that via context menu on a file.

It doesn't matter what file to map, local or site file.

5) at that moment devtools will ask you about restart.

After restart devtools will show you the singe folder entry in the files pane and will apply all the changes you do to the local file each time when you press Ctrl + S or Cmd + S on mac.
