xdg-prefs's Issues

XP-007 Add docs

Documentation should be added in a docs/ folder at the root of the project. It should contain:

the code documentation (extracted from the Python docstrings)
a "user manual" on how to use the application
a "dev manual" on how to contribute, how to delve into the source code, what is the goal of each module,...

The documentation should be set up as Github Pages for easy access.

It would be interesting to change the default program of multiples Media Types at the same time (for example, setting all 'image/...' to be opened by eog).
This should not be difficult not to implement, but requires a clean, intuitive UI.

Segfault on Python 3.12

Hi, I just attempted to install and run this with Python 3.12 on x86_64 Arch Linux. I get a segmentation fault when attempting to launch the program. I put the core dump in the debugger and it appears that there is a bad pointer deference in PyDict_GetItem within cpython. I think it's a case of bad FFI.

Specifically:

PyDict_GetItem:
	endbr64                         
	push   %rbp                     
	mov    %rsp,%rbp                
	push   %r15                     
	push   %r14                     
	push   %r13                     
	push   %r12                     
	push   %rbx                     
	sub    $0x18,%rsp               
	mov    %fs:0x28,%rax            
	mov    %rax,-0x38(%rbp)         
	mov    0x8(%rdi),%rax    ; %rdi is null, 0x8(0x0) is invalid memory

PackageNotFoundError: No package metadata was found for XDG-Prefs

Trying to run this on EndeavourOS Linux x86_64 (with openbox/lxqt) results in an error. I did compile it, but I never did a lot of python development so I'm a bit lost.

running ./compiled/bin/xdg-prefs gives me:

Easier install process

I noticed the README recommends installing by downloading the wheel or cloning the repo.

Actually, you can install directly from the repo with pip install git+https://github.com/rchaput/xdg-prefs. That might be a more straightforward instruction.

That said, have you consider publishing to PyPi, so that it can become just pip install XDG-Prefs?

KeyError: None

Just installed from the whl file and this is what I get:

XP-009 Use the apps database in the associations database

This would allow to:

check if a given application really exists (and thus to filter the list of 'default applications' for each Media Type)
determine which Media Types are associated to each application

option 'application/vnd.ms-word.document.macroenabled.12' in section 'MIME Cache' already exists

Hi there. Firstly, thanks a ton for this program! It's something I'd been looking for for years before I found it, and was even planning on writing my own. Thanks for saving me the trouble :)

This crash seems to occur on startup when there is a duplicate line in /usr/share/applications/mimeinfo.cache.
In my case, there were both of these lines:

application/vnd.ms-word.document.macroEnabled.12
application/vnd.ms-word.document.macroenabled.12

I don't know why this duplicate existed, but it seems that xdg-prefs didn't like it so it just crashed. After removing the duplicate, it works fine again.

Full stack trace, for info:

XP-010 Add tests

Add testing cases (with a framework such as Unittest).
Such tests need to be reproducible on each computer (which is a bit complicated, considering that xdg-prefs changes the user's preferences)
