🎨 Natls 🎨

Why Natls?

Showing file permissions
Showing file size
Showing the date that the file was modified last
Showing the user that the file belongs to
Showing the group that the file belongs to
An easy to use file search
A splash of color to distinguish between files and folders and other file types

Installation

# Through Cargo
cargo install natls

# Through Homebrew
brew install willdoescode/natls/natls

# Through SnapCraft

001 execute
101 read and execute
110 read and write
011 write and execute
111 read write and execute

Format: user-group-other

User: Read, Write, and Execute

rwxrw----

All Groups: Read, Write, and Execute

rwxrwxrwx

⚠️ Natls is currently not supported on Windows

nat's Issues

For gods sake, move the users and groups to the left where they belong to

This way it is too hard for an admin to read.
An please, please, don't say that you want to replace a tool in the LSB.

Rework the permission output

The permission output is confusing to say the least.
Maybe the reason is that you did not understand the permission system yet, so I'll explain and maybe you can use this information to improve your program.

The permissions are stored as a 9 or 12 bit value organized as follows:

3 bits (read, write, executable) for user, group, others
3 bits for setuid, setgid, sticky bit (if available)

Each bit can be set individually making up the permissions.

Now you can represent numbers in decimal form (the usual human system, because we have ten fingers to count with).
But this is not good when talking about bits, because they live in the binary system.

So the permissions rw-rw-r-- would translate to

000110110100

Because this is long and hard to read, you can group the individual sections and represent them as octal numbers.

000 = 0
110 = 6
100 = 4

So the above example would read 0664.

So you are required to display the permissions exactly as you read them out with stat().

If you get 0755 (octal) from stat() you have to display it as rwxr-xr-x - at least of you wish to use the rwx notation. You can invent another notation if you wish, but that must exactly represent the permissions nevertheless.

Another note: you are appending the @ symbol to each of your permission outputs. But the @ symbol is not a matter of style or to look cool - it actually has a meaning. The presence of the @ symbol says that there are extended attributes on that file.

Headline does not adjust when some outputs are turned off

For example:

nat -l -u -p
permissions size last modified user name
  4.1 kB Oct 22 20:20:58 micah Pictures/
  4.1 kB Oct 24 01:57:42 micah Documents/

  4.1 kB Aug  8 19:25:20 micah Music/
  4.1 kB Sep 16 17:54:05 micah tmp/

The headline still has the titles for permissions and user even though they are turned off.

Doesn't draw a headline as in the pictures

I guess the boolean headline_on is false for some reason?
Here's a screenshot:

nat is no longer in the arch user repository

I've received this email on 10/27/2020, 10:46 PM UTC:

Foxboron [1] deleted nat-git [2].

You will no longer receive notifications about this package.

[1] https://aur.archlinux.org/account/Foxboron/
[2] https://aur.archlinux.org/pkgbase/nat-git/

I don't know the reason for this but I think the installation instructions for arch can be removed for now until another maintainer chooses to support this program.

Add windows compatibility.

Add it for windows or i take ur cookies! FBI WILL KNOCK ON YOUR DOOR BRUH

Latest 1.0.8 binary shows version number 1.0.7

Just downloaded https://github.com/willdoescode/nat/releases/download/v1.0.8/nat.macOs.binary
When executing: nat -h it shows:

nat 1.0.7 the ls replacement you never knew you needed

headlines -l flag doesn't add headlines

Looks like the call to draw_headlines got removed here 1397df7 and never got added back in.

Function is still defined, but never called in output().

Do you have something like this for windows?

Run rustfmt

Create your rustfmt.toml config file and run cargo fmt with it so contributing to this project would be easier.

Snap release updates

The issue

The current release on snap does not match the actual version.

Reproduce

install via "sudo snap install natls"
check version of nat with "natls --version"

Things I tried

update nat with "sudo snap refresh natls"

Idea for a fix

Snap should be integrated into a CI like GitHub Actions, Jenkins or similar to automatically update the binary. Or on each release someone should update the binary manually.

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', src/main.rs:280:3

I can see my directory when I'm in the $HOME/cargo/.bin path

But when I'm outside or any other path other that the path where the natls binary is present, this error is thrown

thread 'main' panicked at 'called Option::unwrap() on a None value', src/main.rs:280:3
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

Suggestion: hide hidden files without -a option like ls

Standard ls doesn't show hidden files without the -a option. This is definitely something nat should consider implementing.

Either color-coding the links and/or showing the dir link destination would be nice. You could also add the dir flag with the rwx flags like ls does. I'd also suggest sorting DIR by name by default, if possible.

Really excited about this project. Are you looking for pull requests? I'm not very experienced with cargo, but hey everyone has to start somewhere.

Printing infinite underscores

When executing nat it prints the header correctly but get's stuck printing an infinite amount of underscore characters (Actually not the ASCII underscore character '_' but the space character with some terminal drawing shenenigans). Has to be killed with ^C

My guess would be that the function call draw_headline("group",get_group_by_gid(get_current_gid()).unwrap().name().to_str().unwrap().len() - 5, true); calls draw_headline with a negative line_length so the for-loop runs indefinitely? Not sure though, I haven't looked too closely at the source code.

OS: Arch Linux
Tested terminal emulators: termite and tmux
I tried both: The provided binary as well as building nat-git from the AUR via yay -S nat-git

Comparison with Exa

Hi there,

First of all thanks for this project, it seems to have a lot of nice features compared to the basic ls :)

One thing I think could be great is to show a comparison with Exa, which is another ls replacement that existed for a long time (more than 5 years).

This way, potentiel users could see what benefits Nat delivers compared to Exa.

What do you think?

TimeZone

How to set the time zone? There is a time difference between the display time and the real time

Exec format error

I downloaded nat v1.0.7, sudo mv it to /usr/local/bin, chmod +x /usr/local/bin/nat and run nat

$ nat
bash: /usr/local/bin/nat: cannot execute binary file: Exec format error

I am on Ubuntu 20

Feature request: widescreen layout

For directories with ~100 of files the table layout becomes tricky and requires the user to manually scroll the screen.
'ls' by default uses the window space by adding as many columns as possible and offers more overview that way.
After all, a widescreen is probably the default setup.
Making use of the available window space would increase usability of nat as well.
Maybe it's an option to show two tables next to each other if the space is sufficient.
Not sure if dynamic layouts are possible that way.

Btw: "nat | more" produces output hickups by adding empty lines.

Differences of unsigend numbers

There are some calculations with unsigned integers that may lead to unintended behavior.
E.g., try with a group name with less than 5 characters.

draw_headline("group",get_group_by_gid(get_current_gid()).unwrap().name().to_str().unwrap().len() - 5, true);

Group and date joined together

Group and date don't seem to have a gap between them, see screenshot below:

My rust foo is very weak and I didn't have tome to dig into it. But perhaps you want to know.

Feel free to just close the ticket.

Can not list root directory /

It can not list fs root "/"

$ nat /
Error: Os { code: 2, kind: NotFound, message: "No such file or directory" }

but

$ ls /
Applications	Library		Users		bin		dev		home		private		tmp		var

This is on OS X 10.15

Request: publish to crates.io

cargo install --git https://github.com/willdoescode/nat --tag v1.2.1 does work but it's too long and doesn't work well with cargo-update.

It would be nice to have it published to crates.io.

Fix installation section in README

The installation section in the README looks like a code block but it should be written in plain text font. Also you should provide command on how to copy the file to /usr/local/bin

Add unicode symbols for different file types

You can add some Unicode symbols to each type of item. For example, an icon for a plain text file, a different one for a folder, something else for a symlink. You could also provide a command line flag to turn it off just in case someone uses a font that doesn't support symbols and weird boxes appear in place of the symbols

Does not work with watch

This is an unusual use case, but sometimes I want to see large files being copied and their size growing.

I'd love to use watch natls for those times.

Cargo build fails with "error[E0308]: mismatched types" Error

Issue description

I'm trying to build nat with my Debian 10 installation. It fails with a "error[E0308]: mismatched types" error.

Steps to reproduce the issue

git clone https://github.com/willdoescode/nat.git
cd ./nat
cargo build --release

What's the expected result?

The build should work.

What's the actual result?

The build does not work and fails with the following error Message:

headline not in correlation with columns

First - very nice cli!

It seems that when using the -l flag:
nat -l
I get the headline not in sync:

Distribute as a package

It would be great to be able to install via flatpak, snap and for example apt install command.

Windows 10

Ok Windows 10 is the most used OS. I bet you will get more stars once you add it.

Error: Os { code: 13, kind: PermissionDenied, message: "Permission denied" }

First of all thanks for such a good tool, I try to install this tool on ubuntu20:

apt-get install rustc cargo
cargo install natls

But when I try to execute it, it says I don't have permission.

$ ~/.cargo/bin/natls
Error: Os {code: 13, kind: PermissionDenied, message: "Permission denied"}

When I enter the ~/.cargo/bin/ directory, the execution will succeed

$ natls

Thanks for any reply

Add information that `nat` binary from releases page is a macOS executable

The tool seems to be made for Linux machines from the Readme, but the provided executable is a macOS binary.

nat: Mach-O 64-bit x86_64 executable, flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|PIE|HAS_TLV_DESCRIPTORS>

"nat" just prints endless underscores

I checked out the code and built it with "cargo build --release".

Started the binary and it prints underscores forever.

The "Help" function (-h) works fine.

OS: Arch Linux 64bit

Suggestion: Add to homebrew

It would be great if I could install nat via homebrew. This would make it much easier to update to new versions.
Maybe you could add a tap to homebrew. Since nat is already on github this should be easy.

Feature request: parameters for sorting

It would be nice to have parameters for influencing the order in which the directory content is displayed.
Name, size, and last-modified would be cool options. Not the mention 'directories before files'. ;)

Only underscore output - also in v1.0.8

calling nat plain on any directory just outputs many underlines. Still :(
Debian 10 x64

Endless loop printing whitespaces

When listing some folders, natls starts by printing the folder contents but then goes on to print infinite whitespaces.

I'm not quite sure what causes this but it is always the same folders (i.e. if one folder does it once, it will do it every time).

The example above comes from the examples/basic folder of this project.

I'm on macOS Big Sur, iTerm, zsh 5.8 (x86_64-apple-darwin20.0.0), rustc 1.47.0-nightly (6c8927b0c 2020-07-26), natls 1.2.11

V2.1.9 is not pushed to GitHub

Version 2.1.9 is not released to GitHub. this affected a non working Homebrew installation.
Homebrew tries to install 2.1.9 which is not released yet.

Won't run on Ubuntu 20.10 amd64

Gives the following error message:

bash: /usr/local/bin/nat: Kann die Binärdatei nicht ausführen: Fehler im Format der Programmdatei

(sorry for german error message, means somthing like: cannot execute binary file: error in format).

I guess, some dependencies are missing that are not mentioned in the readme?

panic if uid/gid names does not exist on local system

If you list a (network-)directory containing files with uids/gids that do not exist on the local system nat panics.

In this case get_user_by_uid/get_group_by_gid do return a None, but this is not checked - just unwrapped

Alphabetical

Nice little tool!

I was wondering about the possibility of alphabetising files and folders

As you can see the files are not ordered which can make it a little cumbersome to use

Thanks.

doesn't work for me

The tool does not work for me.
Downloaded and put into /usr/local/bin and changed permissions to 755
When I run it, it just puts lines on my screen.
