Does Inputs can with Key chaining

[fbewivpjsbsby]

1. What version of corn are you using?
   corn-cli 0.9.2
2. What is your operating system?
   Windows 10

Description

I can not use inputs with key chaining.

Steps to reproduce

1. Write this in corn file:

let {
  $extension = {
    auto_tab_discard = {
      '{c2c003ee-bd69-42a2-b0e9-6f34222cb046}' = {
        installation_mode = "normal_installed"
        install_url = "https://addons.mozilla.org/firefox/downloads/latest/auto-tab-discard/latest.xpi"
      }
    }
  }
} in
{
  policies = {
    ExtensionSettings = {
      ..$extension.auto_tab_discard
    }
  }
}

2. run corn [your corn file name].corn -t json It show error:

�[1;31m[E0001]�[0m   --> 14:19
   |
14 |       ..$extension.auto_tab_discard
   |                   ^---
   |
   = expected spread or path_char

Use case

I use key chaining in inputs that make me use like:

{
  ..$extension.some
  ..$extension.other
}

Hey, cool to see Corn being used in the wild!

The way you're trying to use inputs there isn't supported - key chaining is for writing keys at depth; there is no mechanism for reading keys inside an input object like this.

Instead, what you'll want to do is something like this:

let {
  $auto_tab_discard = { ... }
  $extension = { auto_tab_discard = $auto_tab_discard }
} in { 
  policies.ExtensionSettings = $auto_tab_discard
}

Thanks, that is not like nix, will you add functionality to convert files from corn into nix? If I write everything inside input(let block) may confusing the config. I use [prefix name]_name now:

let {
  $preferences_user_enable = {
    Value = true
    Status = "user"
  }
  // "user" preferences persist even if the policy is removed, so
  // if you need to remove them, you should use the clear policy.
  $preferences_user_clear = {
    Value = true
    Status = "clear"
  }

  $extension_normal_install = {
    installation_mode = "normal_installed"
  }

  // telemetry
  $policies_disable_telemetry = {
    DisableTelemetry = true
    DisableFirefoxStudies = true
  }
  // DNS over HTTPS
  $policies_dnsoverhttps = {
    DNSOverHTTPS = {
      Enabled =  true
      ProviderURL = "https://1.1.1.1/dns-query"
      Locked = false
      ExcludedDomains = [""]
    }
  }
  // theme
  // #TODO 'raw data' need git version corn
  $preferences_theme = {
    'toolkit.legacyUserProfileCustomizations.stylesheets' = $preferences_user_enable
    'layout.css.backdrop-filter.enabled' = $preferences_user_enable
    'widget.non-native-theme.use-theme-accent' = $preferences_user_enable
  }
  // ech
  $preferences_ech = {
    'network.dns.echconfig.enabled' = $preferences_user_enable
    'network.dns.http3_echconfig.enabled' = $preferences_user_enable
  }

  // extension
  // Auto Tab Discard
  $extension_auto_tab_discard = {
    'someid' = {
      ..$extension_normal_install
      install_url = "someurl"
    }
  }
  // uBlock Origin
  $extension_ublock_origin = {
    'someid' = {
      ..$extension_normal_install
      install_url = "someurl"
    }
  }
  // NoScript
  $extension_noscript  = {
    'someid' = {
      ..$extension_normal_install
      install_url = "someurl"
    }
  }
} in
{
  policies = {
    // telemetry
    ..$policies_disable_telemetry
    // doh
    ..$policies_dnsoverhttps

    Preferences = {
      // theme
      ..$preferences_theme
      // ech
      ..$preferences_ech
    }

    // extension
    ExtensionSettings = {
      ..$extension_auto_tab_discard
      ..$extension_ublock_origin
      ..$extension_noscript
    }
  }
}

That's not something I'm currently considering. Although Corn takes inspiration from Nix, I don't see the two as competing or aiming for the same goal at all. My opinion is if you need something more like Nix, you should probably use Nix instead.

That said, the idea of being able to read from input objects (like in your initial question) isn't entirely off the table and I may consider adding that in the future.

Thanks!
