There's an inline script and a bunch of inline handlers (`oncommand="Scratchpad.doSomething()").
Priority: -- → P3
Also, there's (at least) an instance of setAttribute("oncommand.... which will probably break when CSP covers XUL commands

Firstly, there was existing use of setAttribute("oncommand",...) - once bug 957980 is resolved, this won't work so I replaced this with an event listener.

Secondly, goUpdateSourceEditorMenuItems was inline in scratchpad.xul. I moved this to scratchpad.js.

Thirdly, there were a number of inline oncommand attributes within scratchpad.xul - I removed these and replaced them with event listeners, added via setupCommands / setupCommand in scratchpad.js.  I left oncommand=";" for each one pending resolution of bug 371900

Finally, I moved the script element for scratchpad.js in scratchpad.xul so they followed the two commandsets containing the above commands (so the elements exist when scratchpad.js attempts to add event listeners to them).

Remove inline scripts from devtools/scratchpad/scratchpad.xul

-----------------------------------------------------------------

Aside from comments below, there's two places in scratchpad.xul that look like they have inline js. Both of them are `onpopupshowing="goUpdateSourceEditorMenuItems()"`. I'm guessing you want to change those as well and add them to setupCommands (or wherever it is moved to). If that's the case, then the top level `goUpdateSourceEditorMenuItems` function can be removed in favor of just inlining that function in the setupCommands code.

To make it more obvious what's being done here, let's do:

  menuitem.addEventListener("command", Scratchpad.openFile.bind(Scratchpad, i));

To make this more declarative, let's do something like:

  let commands = {
    "cmd_gotoLine": () => {
      goDoCommand('cmd_gotoLine');
    },
    "sp-cmd-newWindow": () => {

Invoking setupCommands (or Scratchpad._setupCommands) probably belongs in Scratchpad.onLoad unless there's a specific reason it needs to happen immediately here.

I believe if the command setup is changed to run during Scratchpad.onLoad, then you won't have to move the script down below the commandset (not sure though).

Removed the onpopupshowing attributes, replaced them with Scratchpad._setupPopupShowingListeners. goUpdateSourceEditorMenuItems was only called from the two onpopupshowing attrs so I moved the contents of that to inside the body of _setupPopupShowingListeners too.

Fixed Scratchpad.populateRecentFilesMenu to use bind, as advised.

Moved setupCommands to Scratchpad._setupCommandListeners. Used a more declarative style for command setup, as advised.

Moved invocation of Scratchpad._setupCommandListeners to Scratchpad.onLoad.

Moved script element for scratchpad.js back to it's original position.
