Run from Lib

[brendanjerwin]

I'd like to be able to run nu while the current directory is the nu
managed lib directory.

I envision that we can write a .nu directory in the lib and that .nu
can contain a marker indicating that it is in the lib directory. Then
nu would just do the right thing.

Thoughts?

make it so!
it could 'error' if it is NOT in a 'nu' project

Anyone know the Git algorithm?

I'm pretty sure Git just uses brute force, like we do in PowerShell for posh-git:

function Get-LocalOrParentPath($path) {
    $checkIn = Get-Item .

    while ($checkIn -ne $NULL) {
        $pathToTest = [System.IO.Path]::Combine($checkIn.fullname, $path)
        if (Test-Path $pathToTest) {

            return $pathToTest
        } else {
            $checkIn = $checkIn.parent

        }
    }
    return $null
}
