Doing the search

Our prompt accepts a callback now, so we're ready to implement the search functionality.

We bind a new key:

        .ctrl_f => try e.find(),

Then we define our function:

///////////////////////////////////////////////////////////////////////////////
//
//                              Find
//
///////////////////////////////////////////////////////////////////////////////

/// Start the search prompt.
fn find(e: *Editor) !void {
    const saved = e.view;
    var query = try e.promptForInput("/", saved, findCallback);
    query.deinit(e.alc);
}

In this function, we make a copy of the current View, so that we can restore the cursor position in the case that the search is interrupted.

We get our query, then deinitialize it. It's clear we're missing some piece of the puzzle...

Which brings us to the findCallback() function, which is passed to the prompt.
