Finally fixed a bug that joined the code and added OneUpdater!

Why don't you use a Script Filter for the second step?

Because it was too late yesterday. 😂

 

Version 1.0 is now available and ported to Python 🤗

 

I hope there is no new bug 🤨 ... let me know how it goes...

Where did you get Alfred.py from? That's some really old-school looking code.

Thanks 😢

I created for my own once I started with Python&Alfred. Since it does the Job I never touched it...even if I am not sure if I ever can write high-polished code 😕

I didn't say, and certainly didn't mean, "bad".

 

I just asked because of the old-style classes. I think most Python programmers these days don't even know they exist.

 

There's absolutely nothing wrong with the code. The style is just kinda old-school (old-style classes, camelCase).

😳 really? can you point me to newer-style format or at least what old-style is in my class? Now you made me curious  

 

...and, no worries, every feedback is welcome hand helps...thx for that!

New-style classes inherit from object, e.g. class Item(object):. I don't remember what difference it actually makes (other than Python 3 doesn't support old-style classes), just that in about 2002 they said "you should use new-style classes from now on." Here are the technical details.

 

Similarly, PEP 8, the official Python style guide came out in 2001 and said that we should all use PascalCase for class names and snake_case for everything else. So you tend to only see camelCase in very old code (like plistlib.readPlist from the standard library, or the Twisted library, which has also been around forever).

Ok got it, but this is mostly based coincidences. 

 

For class Item(object) I did not saw the need therefore I ignored it

 

I started with snake_case but then I felt a bit lost aka I was not able to see the differences between variables and methods so I switch to PascalCase. But now I am on the way to switch to snake_case. Furthermore PyCharm always notified me about my old style 😕

 

Thank you for your pointers! I made now the decision to take care of the new_style in the future!

Hey,

 

It doesn't seem to work by my side.

Entering dapp just returns a contact that I've saved as such, but entering a file extension ater it does nothing.

 

Am I missing a step ?

[Acidham]

Did you install duti ?

 

Any WF debug Info when executing ?

[andy4222]

@Acidham `operation not permitted: ./py3.sh` is what I get when trigger the workflow and typing in the extension name. I checked that py3.sh has execute perms

 

duti is installed

Edited June 7 by andy4222

[Acidham]

py3.sh is checking for the latest version of python3. You can easily comment that out for time being in the workflow steps:

e.g.

# ./py3.sh ext.py "$1"
python3 ext.py "$1"

 

Can you also send me the python3 version you are using?

[vitor]

@Acidham You’re probably better off just removing the file and using /usr/bin/python3 directly, no need for the middleman (er, middlescript?)

 

 

Or even just using External Script directly.

 

 

I have confirmed both work in Ventura.

[Acidham]

@vitor yep that is the plan to get rid of py3.sh. Meanwhile, it should work with python3. But first I wanted to get confirmation.

Edited June 8 by Acidham

[andy4222]

@AcidhamTried changing it to python3 and it works on Ventura. Had to change all 3 script filters.

[Acidham]

Yes, all the three, but it was just for debugging. I released a new version and removed `py3.sh` completely.

Hi @Faris Najem

 

I changed handling of duti app dependency. Please try and let me know: https://github.com/Acidham/alfred-default-app/releases/tag/v1.4.3
