Detect and autofill file types by extension

One of the challenges of tracking biology data is the overwhelming number of file formats. If a user leaves the container or archive dropdown blank, this tool:

• Adds the file sizes of each extension
• Sorts the torrent file list by size
• Returns the first matching extension key

In this repo

Please find all the snippets you need to implement a similar feature on your own tracker. See classes/config.php for an idea of how the each format is associated with an array of file extensions. I’ll reproduce an example below so you can see how powerful a general extension parser can be.

$ContainersExtra = [
  'Docker'           => ['dockerfile'],
  'Hard Disk'        => ['fvd', 'dmg', 'esd', 'qcow', 'qcow2', 'qcow3', 'smi', 'swm', 'vdi', 'vhd', 'vhdx', 'vmdk', 'wim'],
  'Optical Disc'     => ['bin', 'ccd', 'cso', 'cue', 'daa', 'isz', 'mdf', 'mds', 'mdx', 'nrg', 'uif'],
  'Python'           => ['pxd', 'py', 'py3', 'pyc', 'pyd', 'pyde', 'pyi', 'pyo', 'pyp', 'pyt', 'pyw', 'pywz', 'pyx', 'pyz', 'rpy', 'xpy'],
  'Jupyter Notebook' => ['ipynb'],
  'Ontology'         => ['cgif', 'cl', 'clif', 'csv', 'htm', 'html', 'kif', 'obo', 'owl', 'rdf', 'rdfa', 'rdfs', 'rif', 'tsv', 'xcl', 'xht', 'xhtml', 'xml'],
  'OpenDocument'     => ['odt', 'fodt', 'ods', 'fods', 'odp', 'fodp', 'odg', 'fodg', 'odf'],
  'Word'             => ['doc', 'dot', 'wbk', 'docx', 'docm', 'dotx', 'dotm', 'docb'],
  'Excel'            => ['xls', 'xlt', 'xlm', 'xlsx', 'xlsm', 'xltx', 'xltm', 'xlsb', 'xla', 'xlam', 'xll', 'xlw'],
  'PowerPoint'       => ['ppt', 'pot', 'pps', 'pptx', 'pptm', 'potx', 'potm', 'ppam', 'ppsx', 'ppsm', 'sldx', 'sldm'],
  'PDF'              => ['pdf', 'fdf', 'xfdf'],
  'Plain'            => ['csv', 'txt'],
  'Other'            => [],
];

Caveats and todos

Test thoroughly before implementing to ensure the behavior is what you expect! You don’t want to ruin the database with unextected “Autofill” formats.

For this reason, extension parsing is disabled on the torrent edit handler for now. The FileList stored in the database, available to the edit form, is a bencoded string instead of a nested array. $Validate->ParseExtensions currently only works with the $Tor->FileList object before its bencoded.

That’s all for now.
