# More Config Ideas

## Prerequisites

### `use` directories as modules

### `const` (exists already)

### Module constants (maybe also full variables)

# spam.nu

const foo = 'foo'
export const foos = [ $foo $foo $foo ]

let bar = 'bar'
export let bars = [ $bar $bar $bar ]

> use spam.nu

> $spam | table -e
foos    0   foo
        1   foo
        2   foo
bars    0   bar
        1   bar
        2   bar

### const eval of subexpressions

### `env from-strings`

New `env` subcommand to convert env strings into values. Handles Path/PATH conversion automatically if not defined in `$env.ENV_CONVERSIONS`.

Can be coded in Nu language as a part of stdlib eventually.

## The Config

# ~/.nushell/config.nu

# today's env.nu + config.nu witout completions merged together
# read-only, could be hardcoded in memory
source default_config.nu

# could be part of default config:
load-env { env from-strings }
use std  # maybe start working on stdlib and ship it with the default config?

# The bellow code handles updates to the default config from user files

const NU_LIB_DIRS = ($NU_LIB_DIRS | append
    # your custom directories
])

const NU_PLUGIN_DIRS = ($NU_PLUGIN_DIRS | append [
    # your custom directories
])

# no need for a user to edit this:
let-env config = do {
    use config
    
    let hooks = ($config | get -i keybindings | default {})
    let keybindings = ($config | get -i keybindings | default {})

    # we can have a helper command in default config to handle these in a more robust way (e.g. deal with duplicates etc.)
    $env.config.hooks = ($env.config.hooks | append $hooks)
    $env.config.keybindings = ($env.config.keybindings | append $keybindings)
    # etc...
}
