Reorder tabs or buffers

  Hi, I would like to move a tab (from new-tabs.js) one position to the left or to the right. Maybe it's easier to change the order of the buffers, not the tabs, so that C-x b (switch_to_buffer) shows also the new order.

  With my limited knowledge of Conkeror internals, I did this first proof of concept. The right solution is probably much easier. Feel free to change this code, to ignore it, to include a corrected version in Conkeror, or to  send me critiques about what I did wrong.

// This tries to move the current tab 1 position to the left
// It is just a proof of concept but it's not usable: the tab is moved, but buffer_next() and buffer_previous() still use the old order. In addition it only works the first time. C-x b is not affected

function test_move_tab_left(window) {

    // Get the tab bar
    var tabbar = window.tab_bar;
    tabbar.update_multiple_attribute(); //¿?

    var bcurrent=window.buffers.current;
    var index = window.buffers.selected_index;

    if (index==0) {return;}
    var bprevious=window.buffers.get_buffer(index-1);


    // remove it from its position
    tabbar.element.removeChild(bcurrent.tab);

    // and place it before the tab which was at our left
    tabbar.element.insertBefore(bcurrent.tab,bprevious.tab);

    // Renumber the tabs.
    for (var i = 0; i < tabbar.element.childNodes.length; i++) {
        tabbar.element.childNodes[i].childNodes[0].value = i + 1;
    }

    // TODO: make sure that the "next" buffer for each tab points to really the tab at the right, so that next_buffer/previous_buffer work


    // we changed the tabs, not the buffers
    // TODO: maybe change the internal buffer ordering too

    // this doesn't seem to work: C-x b doesn't show this
    var bs=window.buffers;
    var bl=bs.buffer_list;

    // I delete [bprevious,bcurrent] and I put [bcurrent,previous]
    bl.splice(index-1,2, bcurrent,bprevious);

    // still focus the original tab
    bs.current=bcurrent;



    // debug (to know that it ended)
    window.minibuffer.show(bl.length);
    return true;
 
}

interactive("test-move-tab-left", "Tries to move the current tab one position to the left. But FAILS", function(I) {test_move_tab_left(I.window); });
define_key(content_buffer_normal_keymap, "M-c", "test-move-tab-left");
