Run Jenu

You need Java Runtime (JRE) Version 8 or up.

• Open an terminal in the folder where you downloaded jenu.jar.
• Type
  java -jar jenu.jar

Now the Jenu window should open.

You may add this as starter to whatever desktop environment you like as well if you specify an absolute path to jenu.jar.

Usage

General:

• Enter the root URL of the site you want to check and press the "Run" button.
• To check files on your local hard drive enter a file URL. Example: file:/home/myname/myhomepage/
  Note the file URLs behave different than HTTP URLs. I.e. server side URL rewrites or redirect do not work, e.g used for default documents like index.html. Mime types may not work as expected too. And depending on your platform URLs might not be checked case sensitively.

• Jenu will check external pages, i.e. pages that do not start with the same folder than the URL entered, by default but links in external pages are ignored.
• Files and folders starting with a '.' are ignored by default.

Configuration:

• To get more options click the menu entry "Site/Preferences...".
• Using the "Site" menu you may save the current configuration to a file.
• You may save the current configuration as default. This is initially loaded when you start Jenu.

View:

• To sort the result click at the column titles. Note that the sort order is not updated when the status of entries changes. This is intentional.
• You may further arrange columns or change their width by dragging the column titles with the mouse.

• The "View" menu lets you switch between "Target view" and "Source View".
  In target view any bad URL is shown as error, regardless how many links point to it. Links with non existent anchors are also shown as errors at the target URL.
  In source view instead all pages that contain bad links are shown as erroneous.
  In general source view shows more errors because the same bad link might be shown twice, while the source view is more like a working set to correct bad links.

• If you double-click on a value in the "Links in" or "Links out" column a detail view of the referred links opens. Here you can find the line numbers where links can be found in the source files.
• If you double-click an URL in any view it is opened in your default browser.
