How do I set make variables from nushell?

[amtoine]

Hi everyone 👋 😋

The setup

i've got the following Makefile, with a simple target which echoes the content of the VAR variable 👌

$ cat Makefile
VAR=default

target:
    @echo "VAR: ${VAR}"

What happens

all of the following work as expected 👌

$ make target
VAR: default

$ make target VAR=
VAR:

$ make target VAR=foo
VAR: foo

i would like to use environment variable inside VAR, e.g. the path of the current directory!
but the next commands do not work 🤔

$ make target VAR=$env.PWD
VAR: nv.PWD

$ make target VAR=$"($env.PWD)"
VAR:

$ make target VAR=($env.PWD)
VAR: (nv.PWD)

even though env.PWD is properly set to the right value, i.e. my $HOME here 👍

$ echo $env.PWD
/home/ants

What i wanted to do

I wanted to have a behaviour similar to what can be done in bash, i.e.

$ bash

$ make target VAR=$PWD
VAR: /home/ants

My question

maybe i've missed something in the string part of the nushell book?
how can i achieve that in nushell? 😮

anyways, cheers 😉 🎉

Maybe try make target $"VAR=($env.PWD)". You probably want to send VAR=/foo/bar/baz to make target, right? From Nushell's point if view it's just a string. It doesn't know that it's supposed to be variable VAR with assigned value /foo/bar/baz, that's the external command's job to interpret. Our string building is also different from bash etc. so that's why your attempts didn't work.

That's exactly what i was looking for 🤩

thanks a lot 😋
