ls implementation with extras

[mike-ward]

Includes most of the usual ls features plus some extras like table format, checksums and icons.

(rebased over latest main, to avoid the mkfifo type mismatch error, that was already fixed on main)

Hi, sorry for the delay.

I just tried the PR, and got a different output with -l:

While I do prefer the output of your version, since it is clearer and easier to read to me,
I think that the goal of the project was to emulate the original GNU coreutils as close as possible, including sorting order and result formatting, so that the tools can be tested/compared against each other.

[JalonSolov]

If you wanted to add an option (that wouldn't be tested against the GNU version), to give the nicer output, that's fine. The default using the regular options should match.

[mike-ward]

makes sense. I'll see what I can do. Also I'm using GNU ls. The ls in Mac is different option-wise and sometimes layout-wise from gls

[mike-ward]

Made some changes to allow the format to look more like GNU. However, there are still significant differences.

• Sorting: the default is to sort by name. Not sure why you get a different result in testing. I can repro here.
• Block size is a rabbit hole I'm not willing to go down. Its implementation varies depending on the system your on.

If your goal is parity with GNU then this pull request is likely not going to work.

No hard feelings. It was fun to write.

GNU ls does case-insensitive sort, while it looked like yours did case-sensitive. That was the main difference in the sort of the files/dirs.

The only other difference was the total blocks line at the top of the GNU version, while yours has (much nicer!) separation of dirs vs files, and total file sizes.

Probably the main thing about these tools... the main reason for doing them... is to be able to use them as "drop-in" replacements for the GNU versions. At least by default, or when using the same options as the GNU tools. Extra options are fine (far as I'm concerned). They just need to look/act the same as much as possible when not using extra options.

[mike-ward]

GNU gls appears to be case sensitive on the Mac.

ls from GNU coreutils on Linux sorts case-insensitive.

[JalonSolov]

It appears Mac's gls is non-compliant in it's default sorting. :-\

[JalonSolov]

@mike-ward Any plans to work on this again? If not, would you be open to someone else taking what's here and running with it?

[mike-ward]

I don't mind at all. Have fun with it.
