Clone of duti (in swift)

cdef is a handy command-line tool to mess with your default applications.

I currently use it to:

• Change default browser to Chrome
• Change .xml handling from Xcode to TextMate

It uses:

• URL
• UTI

Download it from the Releases page

What are UTI? (Uniform Type Identifiers)

Uniform type identifiers (UTIs) provide a unified way to identify data handled within the system, such as documents, pasteboard data, and bundles. This chapter describes the concepts behind UTIs and shows how to specify them in your application bundles.

Have more information on Apple's website

Examples

###Get the default application to open PNG files:

$ cdef -readdefaultuti public.png
public.png -> com.apple.Preview

###Get all applications that can open PNG files:

$ cdef -readalluti public.png
public.png -> com.pixelmatorteam.pixelmator
public.png -> com.tapbots.TweetbotMac
public.png -> com.omnigroup.OmniGraffle6.MacAppStore
public.png -> com.apple.ColorSyncUtility
public.png -> com.apple.Preview

###Get which application will open http:// URLs:

$ cdef -readdefaulturl http
http -> com.apple.Safari

###Change your default browser to Chrome:

$ cdef -writedefaulturl http com.google.chrome

###Get supported URL types for Apple Mail:

$ cdef -readURLTypes /Applications/Mail.app/
mailto
message

###Get supported Document types for Apple Mail:

√        -> Application is default for this type
x        -> Application supports but is not default for this type

(Viewer) -> Application can open these files in read-only
(Editor) -> Application can modify these files
(None)   -> Application does not support this files

$ cdef -readDocumentTypes /Applications/Mail.app/
√ com.apple.mail.email (Viewer)
√ com.apple.mail.emlx (Viewer)
x com.apple.mail.emlx.part (None)
√ com.apple.mail.mbox (Editor)
√ com.apple.mail.imapmbox (Editor)
√ com.apple.mail.ewsmbox (Editor)
√ com.apple.mail.stationery (Editor)

Note: This will prompt a dialog to ask the user to confirm the change to Chrome.

I use it in my deployments as a Casper policy that executes /usr/bin/sudo -u#501 /usr/local/bin/cdef -writedefaulturl http com.google.chrome

Developers

You're more than welcome to contribute to the code!

Everything needed to create a package is under cdef-Package/. Just run cdef-Package/build_pkg.sh !

You will need to change the Team ID & Certificate.

But... please PR so we can keep only one repository.

cdef's Issues

Set the sip & tel client

Any way to set the sip and tel client to MS teams using cdef?

cdef hangs when a console user is not logged in

When run from say, a Jamf Pro extension attribute on a server that no one logs into, instead of quitting gracefully, the application hangs with the error:

_RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL.

and hangs... forever.

Found this out when recons wouldn't complete on my servers for a few months... 😊

Add support for Commander

Commander is a small Swift framework allowing you to craft beautiful command line interfaces in a composable way.
https://swiftpkgs.ng.bluemix.net/package/21520325

Allow specifying either the bundle ID or application path

Apple Silicon version

Hi there!

Thank you for a great tool!

Do you plan on releasing a new version, Universal build, and maybe not in beta anymore?

I don't know of a better solution for changing these settings on client machine, and it has been a great tool for me. I will be grateful!

Thanks!
Søren

Enhancement - man page

Hi,

I've written a suitable man page for cdef and attached it to this issue ticket. What you need to do is give it 755 permissions and copy it into /usr/local/share/man/man1 . It'll show up as expected when you "man cdef".

cdef.1.zip

Apply to all users

Get a switch to apply setting for all users (like for dockutil)

Implement -v or -version flags that displays the version only

Please implement an option that displays the version that I may capture it in an extension attribute in Jamf to make sure what version I have installed across a given deployment. Currently using the following command which works, but if for any reason the format of the help message changes, this will break.

cdef | head -n2 | tail -n1 | awk '{print $2}' | sed 's/v//'

As a switch to get application bundle

Add CSV support
