  530. <dl><dt><a href="https://openuserjs.org/scripts/gaspar_schot/Supercharged_Local_Directory_File_Browser" class="has_icon_before link" target="_blank">Script home: openuserjs.org</a></dt></dl> <dl><dt>GENERAL INFORMATION</dt> <dd>This script works on <strong>local directories</strong>, as well as many remote server-generated index pages or &ldquo;<strong>open directories</strong>&rdquo;.</dd> <dd>By default, userscripts do not run on local file:/// urls, so for this script to work on local directories you will need to enable it in your browser&rsquo;s extension settings (e.g.: For Tampermonkey in Chrome, open the Chrome extensions page, click the details button for Tampermonkey and check &lsquo;Allow access to file URLs&rsquo;).</dd> <dd>To make the script work on a remote <strong>open directory</strong>, you must add its URL to the list of allowed sites in the settings for this userscript, as provided by your userscript manager.</dd> <dd>Because server configurations vary, the script may not work perfectly (or at all) on some open directories. You may also need to allow&mdash;or block&mdash;javascript on some ODs, and/or allow cookies. Please let me know if you encounter any problems.</dd> <dd>This script was developed in the latest version of Vivaldi, running on the latest MacOS. It has been <em>minimally</em> tested in other Chrome-based browsers, Safari, and Firefox, and has been <strong>not</strong> been tested in any other browsers or OSes. No effort has been made to ensure compatibility with older browsers. Please report any issues. </dd></dl> <dl><dt><span class="invert" style="float:left; margin:4px 6px 0 0;">${ SVG_UI_Icons.ui_layout }</span>The UI consists of two main parts:</dt> <dd>(1) the directory list <strong>SIDEBAR</strong> on the left and </dd> <dd>(2) the <strong>CONTENT PANE</strong> on the right.</dd> <dd>The Sidebar shows all the items in the current directory, while the Content Pane shows a preview of items selected in the Sidebar.</dd></dl> <dl><dt>1. The <strong>SIDEBAR</strong> comprises a <strong>HEADER</strong>, the <strong>DIRECTORY LIST</strong> itself, and a <strong>FOOTER</strong>.</dt> <dd>The <strong>Sidebar</strong> is resizeable; it can be hidden completely by clicking the double-chevron icon at the Sidebar top right or typing <b>&#8984;\</b>.</dd></dl>
  531. <dl><dt>1A. The <strong>SIDEBAR HEADER</strong> contains a <strong>Parent Directory</strong> button, a <strong>Parent Directories</strong> menu which displays separate links for all the parent directories, and the <strong>Main Menu</strong>.</dt> <dd>Below these are <strong>Show Details</strong> and <strong>Show Invisibles</strong> items, a <strong>Show Grid</strong> button (when appropriate), and sort by <strong>Name</strong> or <strong>Default</strong> items.</dd> <dd>If <strong>Show Details</strong> is selected, additional sorting options are shown, along with the <strong>Text Editor</strong> item.</dd> <dd>All of these items are also available in the Main Menu, and some can be toggled via keyboard shortcuts (see below).</dd></dl> <dl><dt>1B. The <strong>DIRECTORY LIST</strong> displays the items in the current directory.</dt> <dd>Directory items can be selected with the arrow keys or by clicking.</dd> <dd>Selecting an item will preview it in the content pane.</dd> <dd>Multiple directories, fonts, or images can be selected with shift+arrowkey, cmd+click, or shift+click.</dd> <dd>Directories can be previewed in the content pane or toggled open in the sidebar to create a &ldquo;tree view&rdquo; of the directory by clicking the folder icon or typing Cmd&rarr;.</dd></dl> <dl><dt>1C. The <strong>SIDEBAR FOOTER</strong> displays <strong>Stats</strong> for the items in the current directory.</dt> <dd>Detailed stats can be shown by clicking the footer.</dd> <dd>There is also a popup menu on the right of the footer with options to display the Sidebar directory or the raw directory index in the Content Pane.</dd></dl> <dl><dt>2. The <strong>CONTENT PANE</strong> displays the selected sidebar item.</dt> <dd>The content pane can be focused by tabbing from the sidebar or clicking. Links in HTML files can be navigated via the tab key.</dd> <dd>Clicking the title of the content pane title reveals an EXTM3U-formatted playlist item for use in an EXTM3U file.</dd></dl> <dl><dt>Previewed Content</dt></dl> <dl><dt>Previewed Directories</dt> <dd>Previewed directories in the Content Pane inherit the sorting and other UI preferences from the Sidebar directory list. They can be navigated independently from the Sidebar via the &ldquo;Parent Directory&rdquo; link in the header or Cmd-Up Arrow.</dd> <dd>An item in the content pane header allows previewed directories to be opened into the sidebar.</dd> <dd>A selected item can be previewed by pressing the spacebar. This is similar to the &ldquo;quicklook&rdquo; function in MacOS.</dd> <dd>Double-clicking a selected directory list item or typing Cmd-Down Arrow will open it in the content pane, replacing the previewed directory. Closing the item via the Close Button or Cmd-W will restore the original previewed directory.</dd></dl> </article>

Click it or type <b>&#8984;G</b> to show a grid of the available items.</dd> <dd>Grids can be navigated with the arrow keys, and individual grid items may be viewed by clicking them or pressing <b>Return</b>.</dd> <dd>When a grid item is being viewed, the grid can still be navigated with the arrow keys.</dd> <dd>Closing a selected grid item will show the grid again.</dd></dl> <dl><dt>PLAYLISTS AND FILELISTS (m3u)</dt><dd>The script supports basic .m3u playlists containing links to audio or video files, but it also has custom support for &ldquo;filelists,&rdquo; which are standard .m3u files that contain links to <i>any</i> type of file or directory.</dd> <dd>Playlist files can be opened via the menu item.</dd> <dd>However, for ease of use, if you change the extension of an ordinary .m3u file to .txt, the script will read it normally as an editable text file. Double-clicking such a file in the sidebar or typing <b>&#8984;&darr;</b> or <b>&#8984;+Return</b> will open it as a playlist/filelist. Please note that the text file must begin with &ldquo;#EXTM3U&sdquo; for this work.</dd></dl> <dl><dt>CUE SHEETS (cue)</dt><dd>When a media file (audio or video) is loaded, the script will look for a .cue file in the same directory with <i>EXACTLY</i> the same name as the media file.</dd> <dd>If it finds one, it will load the Track ID, the PERFORMER, the TITLE, and the INDEX (time position) into a menu next to the audio player; there is no support for other commands.</dd> <dd>Tracks can be selected by clicking the item, and played or paused by clicking the selected item.</dd> <dd>.cue files can also be selected independently in the sidebar and edited and saved (locally). This may be handy for creating &ldquo;on the fly&rdquo; bookmarks for a long media track before closing the page.</dd> <dd>Note that you can also create and save (locally) a new .cue file by using the Text Editor.</dd> <dd>Note (MacOS): If you prefer not to clutter the sidebar with .cue files, you may make them invisible by adding a dot to beginning of the file name; the script will still find them.</dd></dl> </article>
