Feature request: Add file permissions and owner to "info" option

[owallb]

Allow setting permissions (mode) and user/group owner to the info option, similar to what is possible in promptfmt.

As an example to illustrate what I'm requesting, imagine this was set in lfrc:

set info mode:user:group:size:time

Which would then give:

I have prepared changes to support this, let me know if the project is interested in having it implemented and I will open a PR.

Hi, I think permission should be straightforward to implement.

But for user/group, this is a bit tricky because if there are different values then it could cause the fields to not align properly. In your example, it works conveniently because the value is always oscar, but that is not always going to be the case for other people. So you will either have to:

• Hardcode the width of the user/group fields to something like 8 characters
• Introduce another configuration option to control this (though IMO it does feel too specific to justify adding such an option)

[owallb]

That's a good point I hadn't considered, I'll see if I can come up with something.

Also I took a very quick look at your fork, you should make documentation changes to doc.md, not doc.txt. It is mentioned somewhat indirectly in CONTRIBUTING.md, hopefully that should help.

Fixed, thanks.

Once solution to the width issue I could think of is to calculate the maximum of user/group before iterating dir.files in printDir().

Using a forced width of ~8 is cleaner to implement but less flexible. I've added the aforementioned approach but I would understand if you prefer using a constant width. I think most people use short names most of the time, anyway.

[joelim-work]

OK, I forgot about the possibility of just doing a second pass to obtain the max user/group widths - that should work too and is probably better than using a hardcoded width.

I think this feature is worth including - if you submit it as a PR I will review it in more detail.
