The DownloadBook extension allows extension Collection to generate PDF files without a local or external MWServe server.

It can use third-party utilities such as pandoc (for ePub, ODT, etc.) or WeasyPrint (for PDF). They exist as packages in many Linux distributions.

Installation

The Collection extension needs to be installed for this extension to work. Moreover, depending on which output formats are chosen also pandoc (for ePub, ODT, etc.) and/or WeasyPrint (for PDF).

• Download and place the file(s) in a directory called DownloadBook in your extensions/ folder.
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'Collection' );
  $wgCollectionDisableDownloadSection = false;
  wfLoadExtension( 'DownloadBook' );
  $wgCollectionMWServeURL = '<URL_OF_YOUR_WIKI_HERE>/wiki/Special:DownloadBook';
  

• Run the update script which will automatically create the necessary database tables that this extension needs.
• Further configure as required.
•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Advanced configuration

You can modify the conversion commands in "LocalSettings.php", for example:

$wgDownloadBookConvertCommand['epub'] = "pandoc --from=html --to=epub {INPUT} -o {OUTPUT}";

Please see the file "extension.json" for other configuration options. Also note that keys in $wgDownloadBookConvertCommand array are the same formats as in Collection (i.e. $wgDownloadBookConvertCommand['rl'] is the command for PDF).

Installing third-party conversion tool is your own risk and responsibility. This extension simply calls that tool, and then provides the result to extension Collection.

Troubleshooting

Add the following to your "LocalSettings.php":

$wgDebugLogGroups['DownloadBook'] = '/path/to/writable/logfile.txt';
