[bug] Error: Reading input from STDIN. Cannot take file params

[HaoZeke]

Running

minify src/js/sideNav.js --mangle.keepClassName --deadcode.keepFnArgs --outFile main.js.min

From the terminal works fine...

However when I run it through tup I get,

Error: Reading input from STDIN. Cannot take file params   

I have it installed with

yarn global add babel-minify

I've not used tup. Maybe you can help debug what happens in tup and apply a fix that works everywhere. PR welcome. Thanks.

This is how we decide which input form to take -

minify/packages/babel-minify/src/cli.js

Lines 258 to 268 in 9d4fbfa

	if (argv._.length <= 0) {
	if (!process.stdin.isTTY) {
	return runStdin(argv, options);
	} else {
	return printHelpInfo({ exitCode: 1 });
	}
	} else if (argv._.length === 1 && (await isFile(argv._[0]))) {
	return runFile(argv, options);
	} else {
	return runArgs(argv, options);
	}

I'm receiving same error message when I am trying to use it with nodemon .

In my npm scripts, I've got this command:"babel:min": "nodemon --watch library --exec \"minify library -d bin\""

In terminal I get following:

❯ npm run babel:min

> ******@0.1.0 babel:min C:\Users\xeho91\**\**
> nodemon --watch library --exec "minify library -d bin"

[nodemon] 1.12.1

I'm having the same error when running through make.

babel-minify dist/$*.js >> $@

[marcofugaro]

Happens to me also when I run npm publish. Here are the relevant scripts

  "build": "rollup -c && npm run minify",
  "minify": "minify build/get-package-github-url.js --out-file build/get-package-github-url.min.js",
  "prepublishOnly": "npm run build"

[boopathi]

I'm not able to reproduce this by calling minify from a makefile or package.json script or nodemon's exec script. Can someone help create a repo that reproduces this issue ?

[curiousdannii]

Works for me now, maybe a dependency was fixed?

Scratch that, I went back to the commit that was broken for me before, and it's still broken now:

https://travis-ci.org/curiousdannii/ifvms.js/builds/322875737

It's now in a branch for you to easily check out.

Same for me when using inside Docker (e.g. with docker build).
Dockerfile:

RUN npm run compress:scripts

package.json's scripts:

"compress:scripts": "minify ./public/scripts.js -d ./public"

Output:

Error: Reading input from STDIN. Cannot take file params

A possible workaround, since minify is outputting to STDIN by default, and if you're using no arguments but -d is to use following notation:

minify < ./public/scripts.js > ./public/scripts.min.js

Note that you'll need to provide different name for the minified file.
