Usage By Example

The use of this project is mainly around UTIs (what's this?) and URL Schemes. You can find a complete list of UTIs here, and a list of URL schemes here.

Set default handler: ovt bind

• Set default handler by bundle path:

  # URL schemes end with `://`
  ovt bind path /Applications/Safari.app/ http://
  
  # UTIs are reverse domain names
  ovt bind path /Applications/Safari.app/ com.adobe.pdf
  
  # Extensions start with a `.`
  ovt bind path /Applications/Safari.app/ .pdf
  
  # ... or you can simply omit the `.`
  ovt bind path /Applications/Safari.app/
  
  # `path` can also be omitted here
  ovt bind /Applications/Safari.app/ pdf
  

• Set default handler by bundle ID:

  # See above, just use `ovt bind id` this time
  ovt bind id com.apple.Safari http://
  

Check file/URL support: ovt check

Find all the file types or URL schemes supported by an app bundle.

• Check support by bundle path:

  ovt check path /Applications/IINA.app # => File Extensions: 3g2, 3gp, aa3, aac, ...
  
  # `path` can be omitted here
  ovt check /Applications/IINA.app/
  

• Check support by bundle ID:

  # See above, just use `ovt check id` this time
  ovt check id com.apple.Safari # => File Extensions: css, download, gif, ...
  

Get bundle ID: ovt id

ovt id /Applications/Safari.app/ # => com.apple.Safari

Look up file/URL claimer(s): ovt lookup

Find all the app bundles which have claimed some file type or URL scheme.

# URL schemes end with `://`
ovt lookup http:// # => com.apple.Safari, ...

# UTIs are reverse domain names
ovt lookup com.adobe.pdf # => com.apple.Preview, ...

# Extensions start with a `.`
ovt lookup .pdf # => com.apple.Preview, ...

# ... or you can simply omit the `.`
ovt lookup pdf # => com.apple.Preview, ...

Get app path: ovt which

# This will return a list of all possible paths
ovt which com.apple.Safari

# Use `--lucky` if you want the first one only
ovt which com.apple.Safari --lucky # => /Applications/Safari.app

UTI utilities: ovt uti

• Get the UTI of a file extension:

  ovt uti from-ext .pdf # => com.adobe.pdp
  
  # ... or you can simply omit the `.`
  ovt uti from-ext pdf # => com.adobe.pdf
  

• Get the possible extension(s) of a UTI:

  ovt uti to-ext public.mpeg-4 # => mp4, mpeg4
  
  # Use `--lucky` if you want the first one only
  ovt uti to-ext public.mpeg-4 --lucky # => mp4
  

• Get the parent(s) of a UTI:

  ovt uti parent public.mpeg-4 # => public.movie
  

• Get the description string of a UTI:

  # This might not work on some machines
  ovt uti describe public.mpeg-4 # => MPEG-4 movie
