Package - nushell - missing support for INI format

Help
1

Hi,

I have installed nushell via:

# /etc/nixos/configuration.nix
{ config, pkgs, ... }:

{
  # ...
  environment.systemPackages = with pkgs; [
    nushell
    # ...
  ];
}

Which install the version 0.112.2.

When I ran the following nushell command

from --help

the output is

Parse a string or binary data into structured data.

You must use one of the following subcommands. Using this command as-is will only produce this help message.

Usage:
  > from 

Subcommands:
  from csv - Parse text as .csv and create table.
  from json - Convert JSON text into structured data.
  from md - Convert markdown text into structured data.
  from msgpack - Convert MessagePack data into Nu values.
  from msgpackz - Convert brotli-compressed MessagePack data into Nu values.
  from nuon - Convert from nuon to structured data.
  from ods - Parse OpenDocument Spreadsheet(.ods) data and create table.
  from ssv - Parse text as space-separated values and create a table. The default minimum number of spaces counted as a separator is 2.
  from toml - Parse text as .toml and create record.
  from tsv - Parse text as .tsv and create table.
  from url - Parse url-encoded string as a record.
  from xlsx - Parse binary Excel(.xlsx) data and create table.
  from xml - Parse text as .xml and create record.
  from yaml - Parse text as .yaml/.yml and create table.
  from yml - Parse text as .yaml/.yml and create table.

# ...

Which means the INI format is not supported.

This is unexpected since nushell (AFAIK) supports this format “natively” (not through a third-party plugin): from ini | Nushell

Question:

Do I need to “pass an extra flag” to activate the support for this format? If so, how?

Thank you for reading :slight_smile:

It looks like home manager provides programs.nushell.plugins, so you could enable it with something like


{
  programs.nushell = {
    enable = true;
    plugins = [ pkgs.nushellPlugins.formats ];
  };
}

This might work as well:


environment.systemPackages = with pkgs; [
  nushell
  nushellPlugins.formats
];

Surely won’t, given the extra work that the nushell module does:

The answer is always: use the module if there is one!

@waffle8946 could I implement something like this as nushell.withPlugins to avoid requiring home manager? Similar to anki.withAddons, etc.

Yes, probably. Terraform is a good example

Here’s an initial pass at a PR for nushell.withPlugins: nuShell: add withPlugins, mv plugins to by-name/nu/nushell/plugins by andrewzah · Pull Request #543446 · NixOS/nixpkgs · GitHub.

Correct solution is to add `programs.nushell` module that implements plugin registration similar to what Home Manager does, not wrapping somebody’s login shell with bash

Will work on restructuring the PR this evening or the next.

Restructured it to use vendor autoloads.
