How do I insert the deno task argument into the middle of that command?

[j-murata]

The following build task is defined in deno.json.
I would like to change the output destination depending on the argument of deno task build <arg>, but I don't know how to do that.

{
  "tasks": {
    "build": "deno compile -o ??? ./src/index.ts"
  }
}

Note that deno compile does not seem to work with the -o flag at the end, as shown below.

{
  "tasks": {
    "build": "deno compile ./src/index.ts -o"
  }
}

If you have any good ideas, I would be happy to hear them.

Is <arg> a set of fixed, pre-determined values?

Hi @BlackAsLight, thank you for your comment.

Is <arg> a set of fixed, pre-determined values?

No, for now I assume that the output path can be determined by the person executing the deno task build.
For example, ./foo.exe, /tmp/bar.exe, etc.

I also tried the following, but somehow Deno.args[0] seems to be undefined.

{
  "tasks": {
    "build": "deno compile -o $(deno eval \"console.log(Deno.args[0])\") ./src/index.ts"
  }
}
