Making a Custom Protocol Handler and URI Scheme! - Part 3

Well, well, back again!

I am bored of saying what are we going to do today!! So, here it is, you don't need to ask! BTW - Sorry, if you find me rude. I don't want to be rude. And, if you are coming here the first time, then check these out first - Part 1, Part 2!

Today's Plan

Today is no code. We are going to working with Windows and some other non-code things! So, get ready.


Python Libraries:

Be familiar with:

  • The Windows Registry


We need to install auto-py-to-exe to convert our application to an executable.

Install using - $ pip install auto-py-to-exe

Done! Everything installed!

Let's Start

Open a new Command Prompt Window and type - auto-py-to-exe

A window similar to this should open -

Now, click browse and locate your python file containing the handler. Then select One File in the next section and Console Based in the Console Window Section. Then, expand the Settings section and Put a path you can remember under Output Directory. and finally, click "CONVERT .PY TO .EXE". After it is complete, close the window and go back to the Command Prompt and type regedit and select yes if a UAC window pops up.

Registry Editor

It is recommended you make a restore point before following the next steps. Changing anything other than what is mentioned here could even break your whole computer. The author is not liable for any changes you do further. Follow the next steps at your own risk.

After you have read the above, follow these steps -

  • Inside Registry Editor right-click HKEY_CLASSES_ROOT and create a new key
  • Name the key whatever you want your protocol to be called! python for my case.
  • Inside the python key create a new String Value and name it "URL Protocol"
  • Under python create a new key and name it shell. Under shell create new key and name it open.
  • And finally, under shell create a key named command.
  • Now inside command change the value of (Default) to this "D:/path/to/your/exe/file/within/quotes" "%1"
  • And Done! Now close registry editor and open up a browser.
  • Type - python://D:/path/to/any/python/ in the address bar and press enter.
  • Enjoy!

I am Super Sorry

I did not post for the past month or so... Don't be mad. I was working on the Documentation for py-everything. And that took all of my time... I had this post written before hand just a tiny part was left and I couldn't complete it. But now I am super happy to publish this post and also announce that py-everything 2.0.0 just got released with tons of new features, CLIs, modules, etc. So go check that out as well. 😒
