Processing variables on MacOS 10.15.2 only works with single quotes

[mansn]

• cross-env version: 6.0.3
• node version: 12.8.0
• npm version: 6.11.3
• MacOS: 10.15.2 (Catalina)

Put these rules into a package.json file with the cross-env node module installed.

"greet": "npm run greet0 && npm run greet1 && npm run greet2",
"greet0": "cross-env-shell GREETING=Hi NAME=Joe echo unquoted $GREETING $NAME",
"greet1": "cross-env-shell GREETING=Hi NAME=Joe \"echo doubleQuotes $GREETING $NAME\"",
"greet2": "cross-env-shell GREETING=Hi NAME=Joe 'echo singleQuotes $GREETING $NAME'"

npm run greet
See what gets echoed.

This is what I see:

MacOS 10.15.2	Expected(?)	Comment
unquoted	unquoted Hi Joe
doubleQuotes	doubleQuotes Hi Joe	I guess this is actually the expected result atm?
singleQuotes Hi Joe	singleQuotes Hi Joe

Unfortunately I cannot verify the behavior on Windows.

Problem description:
This problem is pretty much the same as described in #148.
The README.md example shows that you should wrap commands in (double) quotes ("\) if you want environment variable(s) to apply to a series of commands: https://github.com/kentcdodds/cross-env#cross-env-vs-cross-env-shell. But this example doesn't work on MacOS 10.15.2.

Suggested solution:
Unfortunately I haven't had the time to dig into the codebase to propose a solution, other than that "it should work with double qoutes".

I am also facing this exact problem. You found any workaround?

[mansn]

@danielo515 No, not really any workaround. I mean, I use single quotes, but then the npm script won't work on Windows..
Maybe asking Windows users to switch script-shell to powershell could work for them? I.e. by following these guidelines, and then just use single quotes.

@danielo515 @mansn How bout this pattern below? 👇

"greetDriver": "cross-env GREETING=Hi NAME=Joe npm run greet",
"greet": "npm run greet0 && npm run greet1 && npm run greet2",
"greet0": "cross-env-shell echo unquoted $GREETING $NAME",
"greet1": "cross-env-shell \"echo doubleQuotes $GREETING $NAME\"",
"greet2": "cross-env-shell 'echo singleQuotes $GREETING $NAME'" 

...and then npm run greetDriver or yarn greetDriver should do the job. 😃✨
