This is a chrome extension built using chromex and boot. It uses boot chromex sample as a starting point.

This lets users bind keybindings to various text selection commands. These are configured from the extension's popup. The various commands available currently are expand-current-selection.

Install the latest Chrome Canary with custom formatters enabled.

To build locally open up Emacs and start a Clojure REPL with M-x cider-jack-in. Then from the REPL do:

boot.user=> (def p (future (boot run)))

Now open Chrome Canary and go to the Extensions page. Enable Developer mode and add target/ via "Load unpacked extension...".

The icon to open the popup should appear next to the address bar.

To start a REPL that will connect to the popup from Emacs right click on the icon and select "Inspect Popup". Go to the sources page of Developer Tools and open popup.html in a new tab.

Now back at the Clojure REPL:

boot.user=> (start-repl)

If this does not connect refresh the popup page. Now we're connected!

From a terminal window do:

$ boot production

Load the extension by adding target/ via "Load unpacked extension..." to test the extension. Finally use Chrome's "Pack extension" tool to prepare the final package (.crx and .pem files)

There is code for storage and selection in src/util. storage.cljs uses the Chromex Storage API to facilitate communication between the content script and popup, and selection.cljs contains code to extend the current text selection.

The content script, the code that is injected into the page, is located in src/content_script. This sets up a keyboard listener and when there is a match alters the current text selection using code from the selection namespace.

The popup code located in src/popup is for setting and getting the data from the popup.

• Add customizable selections
• Support for more complex keybindings
