Maintainer CC

@XYenon for yazi integration
@jpteb for zoxide integration, as the latest editor, since it seems the original maintainer had left the community (sadly)

Do I also need to CC the maintainer of the xonsh package in nixpkgs?

[jpteb]

Hi, I've finally had a look and the integration with zoxide looks good to me.

[inmaldrerah]

Thanks. By the way, how can I initiate the tests? Should I ping someone or just wait for maintainer approval?

[inmaldrerah]

Sorry, I forgot to use hm.maintainers. Should be fixed now.

[inmaldrerah]

Could any maintainer help with the approval please?

I'm not familiar with xonsh. But I have taken a look of the document, and I think it uses an alias instead of a init() function.

I'm not familiar with xonsh. But I have taken a look of the document, and I think it uses an alias instead of a init() function.

Ah yes, Xonsh does use aliases to make a Pythonic function available as a Shell-like command, and that's why I set the field of aliases here.

In Xonsh, using def will make the function available directly as that name in a Pythonic manner. If ya(arg) is defined directly (without being wrapped by init()) and "ya" is set as an alias of the ya function (aliases["ya"] = ya), it will be available as both a shell-like command and a Pythonic function, and Xonsh will prefer the latter when only ya is typed and will print str(ya) rather than call ya([]).

The init() function is neither recognized nor directly called by Xonsh. Instead, it is called immediately after it is created, and then deled. In this way, the ya(args) function will stay inside the body of the init() function, and alias["ya"] will be a function inside a closure, making it impossible to directly call ya with ya(args), only possible through the shell alias, i.e. ya, or ya path/to/folder/or/file.

But I have to admit init is not a good name, as it might collide with other functions defined with that name. I'm going to change it to __yazi_init.

Could anyone help with workflow approval?
