nushell env wrapper

[joknoll]

Description

As a developer using Vite+ I want to be able to source vp into nushell so that I can still use my main shell.

This includes wrapping the env use command and completions for vp.

Suggested solution

I've already implemented a env.nu that can be sourced in nushell like so 'source ~/.vite-plus/env.nu'

# Custom completer for the vp wrapper using fish completions
def "nu-complete vp" [context: string] {
    let fish_comp_path = ($env.HOME | path join ".vite-plus/completion/vp.fish")
    let fish_cmd = $"source '($fish_comp_path)'; complete '--do-complete=($context)'"
    fish --command $fish_cmd | from tsv --flexible --noheaders --no-infer | rename value description | update value {|row|
        let value = $row.value
        let need_quote = ['\' ',' '[' ']' '(' ')' ' ' '\t' "'" '"' "`"] | any {$in in $value}
        if ($need_quote and ($value | path exists)) {
            let expanded_path = if ($value starts-with ~) {$value | path expand --no-symlink} else {$value}
            $'"($expanded_path | str replace --all "\"" "\\\"")"'
        } else {$value}
    }
}
export def --env --wrapped vp [...args: string@"nu-complete vp"] { match $args {
    ["env", "use", ..] => {
        let out = (with-env { VITE_PLUS_ENV_USE_EVAL_ENABLE: "1" } {
                ^vp ...$args
            })
        let out_lines = ($out | lines)
        let exports = (
            $out_lines | find -r '^export ' | parse -r '^export (?P<key>\w+)=["'']?(?P<value>[^"'']+)["'']?' | reduce -f {} {|it, acc| $acc | insert $it.key $it.value}
        )
        if not ($exports | is-empty) {
            load-env $exports
        }
        let unsets = (
            $out_lines | find -r '^unset ' | parse -r '^unset (?P<key>\w+)' | get key
        )
        for key in $unsets { hide-env $key }
    }
    _ => { ^vp ...$args }
} }
