Args not passed to other process

[OlivierKamers]

For example: dotenv mvn exec:java -Dexec.args="-g -f" does not pass those -g -f args into the Java method, whilst mvn exec:java -Dexec.args="-g -f" works in this case.

[entropitor]

Does dotenv mvn exec:java -- -Dexec.args="-g -f" work?

I had a similar problem and it was fixed by adding --.

Thanks for the tip, @entropitor

So how do you run dotenv node --experimental-modules server.mjs?

It just hangs without doing anything...

[entropitor]

I'm guessing dotenv node -- --experimental-modules server.mjs.

Basically any command line flag you want to parse to a the subprocess you're creating should be behind the -- as dotenv-cli will ignore everything after there

Maybe we can refactor by use commander

It is simple to write a command tool.

Then We can use dotenv-cli like this

dotenv -e .env1 .env2 .env3 command <My command with args>

[entropitor]

@xyy94813 What's the advantage? You can already do this, as describe in this issue and by the README: https://github.com/entropitor/dotenv-cli#flags-to-the-underlying-command

You just need to add --

dotenv -e .env1 .env2 .env3 -- command <My command with args>

[xyy94813]

What's the advantage?
Emmm... You can ignore the way I suggest to use it.

But refactor by command the code will be easy to read.

When i use dotenv-cli without <My command>,

Throw a Error: [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type undefined

It took me a long time to find out the cause of the problem.

dotenv-cli/cli.js

Line 27 in 0bef67a

spawn(argv._[0], argv._.slice(1), { stdio: 'inherit' })

Because argv._[0] is undefined

In addition, I hope that my use of the scene can bring a little inspiration

The following is my usage scenario：

---

Normally, i just need the default .env.
So, i just need configure script like this in package.json

{
"scripts": {
    "dev": "dotenv next dev"
  },
}

it is work well too

{
"scripts": {
    "dev": "dotenv -- next dev"
  },
}

But, some time i need to debug in diff deploy environment.
And i do not want to configure many script in package.json, because they are not commonly used.

I choice the first config, so that i can do something like this:

yarn run dev -e .env.debug.local

Woo~, everything in my control

---

The command next dev support a arg --port to control dev server port

if i use the arg --port base script dev

yarn run dev -e .env.debug.local -- --port  3001
// it is seem work well, actually not

Because yarn will ignore the first --

warning From Yarn 1.0 onwards, scripts don't require "--" for options to be forwarded. In a future version, any explicit "--" will be forwarded as-is to the scripts.
// what you excute command is
// yarn run dev -e .env.debug.local --port  3001

yarn run dev -e .env.debug.local -- -- --port 3001
npm run dev -e .env.debug.local -- -- --port 3001
// work well, but too many `--`, and It's hard to understand what command did

[xyy94813]

dotenv MyCommand -e XXX not equal dotenv -- MyCommand -e XXX

It is a bit counterintuitive

[entropitor]

The -- is very common see e.g. https://unix.stackexchange.com/questions/11376/what-does-double-dash-mean-also-known-as-bare-double-dash

And your use-case is exactly an example of one why we want such a thing. Without it, the -e .env.debug.local flag would be passed to the next dev executable, NOT to dotenv

Feel free to fork the repo and publish your own version btw, but I believe it's better if we do use the --

[galleonpt]

I have a similar problem and tried with "--" but it still doesn't work.
My example:

I have the following script in my package.json

"test": "dotenv -e .env.test && docker compose up -d && yarn prisma migrate deploy && jest -i"

When I run yarn test it doesn't work.

How should I write my command? @entropitor

[entropitor]

dotenv -e .env.test -- bash -c "docker compose up -d && yarn prisma migrate deploy && jest -i"

If it doesn't, I don't know by hard. This is basic shell priority, this CLI doesn't do anything special
