// The following are various examples taken from README.md. Each section
// contains code that you could place into your own custom.js file. Note that
// only one of these should be used, though you might want to combine ideas
// from the various examples.
//// 1. Simple "My favorites" menu inserted at the *bottom* of "Snippets", with horizontal-line separator
require(["nbextensions/snippets_menu/main"], function (snippets_menu) {
console.log('Loading `snippets_menu` customizations from `custom.js`');

'snippet' : ['new_command(3.14)',],
},

snippets_menu.options['menus'][0]['sub-menu'].push(my_favorites);
console.log('Loaded `snippets_menu` customizations from `custom.js`');
});
//// 2. "My favorites" menu with lots of stringy goodness
require(["nbextensions/snippets_menu/main"], function (snippets_menu) {
console.log('Loading `snippets_menu` customizations from `custom.js`');
var horizontal_line = '---';

snippets_menu.options['menus'][0]['sub-menu'].push(my_favorites);
console.log('Loaded `snippets_menu` customizations from `custom.js`');

//// 3. Delete "Matplotlib"'s "Setup for scripts" item
require(["nbextensions/snippets_menu/main"], function (snippets_menu) {
console.log('Loading `snippets_menu` customizations from `custom.js`');
snippets_menu.python.matplotlib['sub-menu'].splice(1, 1); // Delete 1 element starting at position 1 of the sub-menu

var tmp = snippets_menu.python.matplotlib['sub-menu'][0];

snippets_menu.python.matplotlib['sub-menu'][1] = tmp;
console.log('Loaded `snippets_menu` customizations from `custom.js`');

//// 5. Insert "My favorites" as a new top-level menu before "Snippets", instead of inside "Snippets"

//// 8. Move SymPy and Numpy to navbar and delete pandas
require(["nbextensions/snippets_menu/main"], function (snippets_menu) {
console.log('Loading `snippets_menu` customizations from `custom.js`');
snippets_menu.default_menus[0]['sub-menu'].splice(3, 2); // Remove SymPy and pandas

snippets_menu.options['menus'].push(snippets_menu.python.numpy); // Follow that with a new Numpy menu
console.log('Loaded `snippets_menu` customizations from `custom.js`');

//// 9. Change direction of sub-menus under "Snippets"
require(["nbextensions/snippets_menu/main"], function (snippets_menu) {
console.log('Loading `snippets_menu` customizations from `custom.js`');
snippets_menu.options['direction_of_top_level_submenu'] = 'right';

//// 10. Place "Snippets" inside "Insert" menu
require(["nbextensions/snippets_menu/main"], function (snippets_menu) {
console.log('Loading `snippets_menu` customizations from `custom.js`');
snippets_menu.default_menus[0]['menu-direction'] = 'left'; // Open top-level menu to the left...
snippets_menu.default_menus[0]['sub-menu-direction'] = 'right'; // ...and sub-menus to the right.
snippets_menu.options['menus'].push('---', snippets_menu.default_menus[0]); // Add horizontal line and default menus
snippets_menu.options['sibling'] = $("#insert_cell_below"); // Find the place at which to insert the new menus
console.log('Loaded `snippets_menu` customizations from `custom.js`');

//// 11. Multiple menus in different places
require(["nbextensions/snippets_menu/main"], function (snippets_menu) {
