Expose some commands to external world

Related problem

Nushell actually could replace some other tools like: jo, jq, jy, wget, table ...

Even if people don't download it because of shell or script, they could install as bundle of tools,

But call nu -c 'i need to learn nu' isn't nice.

No I'm not asking to expose all commands, only those super cool

Describe the solution you'd like

Provide some scripts to help user integrate it with their current shell/workflow without requiring to learn nu.

IE:

#/usr/bin/nu --stdin
# convert formats --inputFormat|-i format --outputFormat|-o format
def main [
   --inputFormat (-i): string = nuon,
   --outputFormat (-o): string = json] {
    $in |  if $inputFormat in [json]     {
        from json
    } else if $inputFormat in [nu nuon]  {
        from nuon
    } else if $inputFormat in [tml toml] {
        from toml
    } else if $inputFormat in [yml yaml] {
        from yaml
    }|     if $outputFormat in [json]     {
        to json
    } else if $outputFormat in [nuon nu]  {
        to nuon
    } else if $outputFormat in [toml tml] {
        to toml
    } else if $outputFormat in [yaml yml] {
        to yaml
    }
}

Now user can call

curl "http://bla.bla" | nuon -o  toml

Instead of

curl "http://bla.bla" | nu --stdin -c '$in | from json | to toml'

Describe alternatives you've considered

There are alternatives to that, but all them comes in different packages and installation process.

Additional context and details

What commands expose and how expose is up to you, the one above is just a suggestion.

I know that nu_scripts have some cool ones, I liked ymd and dmy

this is kinda cool 😮

i'm not sure what the request here really is @hugosenari 🤔
this is just a script that people could download and use without dropping in the Nushell REPL, do you mean it could be somehow bundled with the nu binary?

[hugosenari]

use without dropping in the Nushell REPL

Neither the Nushell Script, ;-)
Nothing against it, I love it, but being honest, make people migrate from Sh/Bash/Ksh REPL/Script to Nushell isn't easy, maybe we could make them install Nushelll as 'tool' first to use in their current REPL/script, them as script, and finally as REPL.

it could be somehow bundled with the nu binary

👿 "Overnight, Netscape's, primary product had been reduced to a feature of another, more popular product."¹

One more or less similar example of this in the wild is python -m http.server
While that explores other feature (run installed packages) and could have better discoverability (UX), we don't need install nothing other than python to use it and is much more simple than 'python -c "import http.server as s; s()"

we have started writing a package manager for Nushell, i guess this could be part of an official package and installed that way.
or it could be part of the standard library and you'd simply have to use ... and then call the command 👍

[sholderbach]

We want to focus on getting the experience inside nushell right and probably won't be able to dedicate design time to get the interface of native Nu commands with an outside POSIX shell right and stable.

Closing it for now 😉
