/* * sidebar.js * ~~~~~~~~~~ * * This script makes the Sphinx sidebar collapsible. * * .sphinxsidebar contains .sphinxsidebarwrapper. This script adds * in .sphixsidebar, after .sphinxsidebarwrapper, the #sidebarbutton * used to collapse and expand the sidebar. * * When the sidebar is collapsed the .sphinxsidebarwrapper is hidden * and the width of the sidebar and the margin-left of the document * are decreased. When the sidebar is expanded the opposite happens. * This script saves a per-browser/per-session cookie used to * remember the position of the sidebar among the pages. * Once the browser is closed the cookie is deleted and the position * reset to the default (expanded). * * :copyright: Copyright 2007-2015 by the Sphinx team, see AUTHORS. * :license: BSD, see LICENSE for details. * */ $(function() { // global elements used by the functions. // the 'sidebarbutton' element is defined as global after its // creation, in the add_sidebar_button function var bodywrapper = $('.bodywrapper'); var sidebar = $('.sphinxsidebar'); var sidebarwrapper = $('.sphinxsidebarwrapper'); // for some reason, the document has no sidebar; do not run into errors if (!sidebar.length) return; // original margin-left of the bodywrapper and width of the sidebar // with the sidebar expanded var bw_margin_expanded = bodywrapper.css('margin-left'); var ssb_width_expanded = sidebar.width(); // margin-left of the bodywrapper and width of the sidebar // with the sidebar collapsed var bw_margin_collapsed = '.8em'; var ssb_width_collapsed = '.8em'; // colors used by the current theme var dark_color = $('.related').css('background-color'); var light_color = $('.document').css('background-color'); function sidebar_is_collapsed() { return sidebarwrapper.is(':not(:visible)'); } function toggle_sidebar() { if (sidebar_is_collapsed()) expand_sidebar(); else collapse_sidebar(); } function collapse_sidebar() { sidebarwrapper.hide(); sidebar.css('width', ssb_width_collapsed); bodywrapper.css('margin-left', bw_margin_collapsed); sidebarbutton.css({ 'margin-left': '0', 'height': bodywrapper.height() }); sidebarbutton.find('span').text('»'); sidebarbutton.attr('title', _('Expand sidebar')); document.cookie = 'sidebar=collapsed'; } function expand_sidebar() { bodywrapper.css('margin-left', bw_margin_expanded); sidebar.css('width', ssb_width_expanded); sidebarwrapper.show(); sidebarbutton.css({ 'margin-left': ssb_width_expanded-12, 'height': bodywrapper.height() }); sidebarbutton.find('span').text('«'); sidebarbutton.attr('title', _('Collapse sidebar')); document.cookie = 'sidebar=expanded'; } function add_sidebar_button() { sidebarwrapper.css({ 'float': 'left', 'margin-right': '0', 'width': ssb_width_expanded - 28 }); // create the button sidebar.append( '
