To register a new file extension with an application use the following defaults command. 
Replace PUT_FILE_EXTENSION_HERE_WITHOUT_PERIOD with the file extension i.e. txt. 
Replace org.category.program with the com/org name of your program i.e. com.apple.itunes.

<pre><code>$ defaults write com.apple.LaunchServices LSHandlers -array-add \
"&lt;dict&gt;&lt;key&gt;LSHandlerContentTag&lt;/key&gt;
&lt;string&gt;PUT_FILE_EXTENSION_HERE_WITHOUT_PERIOD&lt;/string&gt;&lt;key&gt;LSHandlerContentTagClass&lt;/key&gt;
&lt;string&gt;public.filename-extension&lt;/string&gt;&lt;key&gt;LSHandlerRoleAll&lt;/key&gt;
&lt;string&gt;org.category.program&lt;/string&gt;&lt;/dict&gt;"
</code></pre>

 

Once you have added the file extension to the launch services, you must restart the launch services deamon so it will re-read the configuration file. 

You can either run the command below to restart launch services, or simply restart your computer. Loging in/loging out also might do it but I haven't tried.

<pre><code>$ /System/Library/Frameworks/CoreServices.framework/Versions/A/Framework/LaunchServices.framework/Versions/A/Support/lsregister -kill -domain local -domain system -domain user

This involves bundling your application via py2app, adding certain key to your Info.plist file and installing event handlers in your app.

If you right click on your .app file and choose "Show package contents", there will be a folder called <code>Contents</code>, and in that folder, there will be a file called <code>info.plist</code> and a folder called <code>Resources</code> (if any of these don't exist, create them). If you want to associate the file extension <code>.myfileextension</code> with your program and you want files with that extension to have the icon contained in a file called <code>icon.icns</code>, copy the file <code>icon.icns</code> into the <code>Resources</code> folder and add the following code to the <code>info.plist</code> file right before the <code>&lt;/dict&gt;</code> tag:

<pre class="lang-xml prettyprint-override"><code>&lt;array&gt;
 &lt;dict&gt;
 &lt;key&gt;CFBundleTypeRole&lt;/key&gt;
 &lt;string&gt;Editor&lt;/string&gt;
 &lt;key&gt;CFBundleTypeIconFile&lt;/key&gt;
 &lt;string&gt;icon.icns&lt;/string&gt; &lt;!-- change this --&gt;
 &lt;key&gt;CFBundleTypeExtensions&lt;/key&gt;
 &lt;array&gt;
 &lt;string&gt;myfileextension&lt;/string&gt; &lt;!-- change this --&gt;
 &lt;/array&gt;
 &lt;key&gt;CFBundleTypeName&lt;/key&gt;
 &lt;string&gt;File extension description&lt;/string&gt; &lt;!-- change this --&gt;
 &lt;key&gt;LSHandlerRank&lt;/key&gt;
 &lt;string&gt;Owner&lt;/string&gt;
 &lt;/dict&gt;
&lt;/array&gt;
</code></pre>

The lines marked <code>&lt;!-- change this --&gt;</code> in the above code should be changed according to what properties you want the extension to have. <code>icon.icns</code> should be changed to whatever name the icon you put in the <code>Resources</code> folder and you want the file extension to have is called, <code>myfileextension</code> should be changed to the file extension that you want to associate with your program (without the dot), and <code>File extension description</code> should be changed to the description you want the file extension to have (for example for .doc files it would be "Microsoft Word document").

Also, you can check <a href="https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html#//apple_ref/doc/uid/20001431-101685" rel="nofollow noreferrer">here</a> to see what the other values mean and if you need to change them. There are also other values listed there that you can add if you need them.

I'm trying to get my program to automatically associate certain file extensions to be opened by it but I'm not sure how to do that in MacOSX. I'm not asking how to associate a program with a file extension in the GUI, I want to be able to program it into my program.

我试图让我的程序自动关联要由它打开的某些文件扩展名，但我不确定如何在MacOSX中做到这一点。我不是问如何在GUI中将程序与文件扩展名相关联，我希望能够将其编程到我的程序中。
