#nushell — Public Fediverse posts

Here’s a quick #nushell tip for apps that don’t have auto-reload on configuration changes:

let $app = the-program-in-question
watch $"( $nu.home-dir )/.config/( $app )" {
ps | where name == $app | first | kill -s 12 $in.pid
}

Launch it however you like. The command “kill -s 12” sends a reload signal.

Hello #fediverse from my new #mbin account!

I write #java for work, and #rust + #nushell at home. I will absolutely ramble about things I have no idea on :p

I love #reverseengineering and #binaries, will work on anything and everything low level. I love OS level shit, from the desktop ux to driver stability. I will absolutely ramble about #linux #arch and #nixos

A serial #matrix enjoyer, text me at @innocentzer0:tchncs.de or @innocentzer0:cyberia.club

I occasionally dabble with functional programming, and will totally not shut up about programming ergonomics and type systems and such, even though I cannot write a compiler for C if my life depended on it.

As an aside, avid movie watcher, reader, manga enjoyer, anime enjoyer, and fanfic reader. Occasionally dabble in writing fanfics of my own. My blog and contains my unhinged ramblings.

I ABSOLUTELY LOVE receiving email, please send me some at [email protected]

Here to have fun and enjoy!

`ls | each { update name ( open $in.name ) }`

That alone gets you (OK, me) about 75 percent of the way to a working notes system. A scratchpad, if you will.

#nushell is neat.

I often get frustrated when copy-pasting commands from a website into my Nushell terminal, especially with those line-escaping backslashes...

Here is a little snippet I found to solve that issue.

Labels are flattened into the output by default now, use --no-flatten in case you have an overlapping label like "name".

Nushell é uma shell que estrutura a saída dos comandos em tabelas, em vez de texto simples. Em vez de awk/sed, usas where e sort-by para filtrar e ordenar dados diretamente.

Ex: ls | sort-by size | reverse

I'm curious if anyone knows of any attempts to make GUI applications composeable like shell scripts, taking the output of one program and piping it into another. I was reading about #nushell and it's structed data formatting made me think that this could be a few steps away from have GUI applications feed data to each other to compose a whole new GUI application.

What's bloating up your NixOS configuration? Here are some handy Nushell scripts to find out:

# Total size of your configuration
nix path-info --closure-size --human-readable .#nixosConfigurations.(hostname).config.system.build.toplevel

# Size of largest packages
nix path-info --recursive .#nixosConfigurations.(hostname).config.system.build.toplevel | lines | par-each { |it| du $it | first } | rename path apparent physical | sort-by apparent --reverse | take 20

# Size of largest clojures (packages, including respective dependencies)
nix path-info --closure-size --recursive .#nixosConfigurations.(hostname).config.system.build.toplevel | detect columns --no-headers | rename path size | into filesize size | sort-by size --reverse | take 20

You can sync this file to multiple computers and edit it however you like, e.g. in vim, helix or Obsidian.

Here is what I added to my `config.nu` for #nushell, I can even do `shortcuts --help` this way:
```nu
def shortcuts [
search_string: string # Will be expanded from input e.g. `helix` to `'# helix'`.
] {
mdq $"# ($search_string)" $env.SHORTCUTS_FILE | glow # $env.SHORTCUTS_FILE is defined in `env.nu`
}

```

(Sorry if this doesn't render nice in your Mastodon frontend)

Nushell made shell scripting really enjoyable. I started my journey 15 years back with bash, moved to bash-incompatible fish, never could really used xonsh due to speed.

But, Nushell is a whole another beast! Data really became a first-class citizen, scripting is powerful and fun, integrations are excellent.

Best module I've defined for #nushell & #hyprland this week:

def hyprrun [ command_run: string ] {
hyprctl eval $"hl.exec_cmd\( \"($command_run)\" \)"
}

Handy when you want to run something in the hyprland context, not your terminal window

RE: https://mastodon.social/@h4ckernews/116623104745963278

I hate #bash for it's syntax, that's why I turned to #Nushell, which is much cleaner and looks a little more like #ruby. But it is not posix-compatible, which is kind of annoying sometimes.

This shell brings the best of both worlds.

Using ruby to do complex shell commands... Gotta try it out!

Nushell Niceties: Wrapping External Commands With def --wrapped
A blog by @mrhaki

The def keyword in Nushell is used to define a custom command. By adding the --wrapped flag you can tell Nushell to accept unknown flags and arguments and pass them on as strings. In the command parameters you use a "rest" parameter defined by …​ to capture the remaining arguments. Then in the command body you use the spread operator …​ to expand them...

Nushell Niceties: Check Semantic Version Is A Match
A blog by @mrhaki

In a previous blogpost you can learn about the semver command in Nushell to transform a string value into a semver type. The command has a subcommand match-req. You can use this command to check if a version matches part of the semantic version parts. The result is a boolean value. The version to compare with doesn’t have to defined fully, but could exist of only...

Nushell Niceties: Sorting Version Values With Semver Ordering
A blog by @mrhaki

The semver Nushell plugin can be used to work with string values as semver type as you can see in a previous post. You can use the semver sort command to sort string values with ordering rules for semantic versions. With natural ordering of string values a value of 10.0.1 is placed before 2.1.0, but if you use semver sort the ordering will be correct....
