How can I get the entry file name in the loaders?

[weekeight]

If I have a entry hello.js like this:

require('./images/test.png');

and I use file-loader to handle this, then I want the built image named as "hello.test.png",how can I make it?

The following example can not fill my need:

{
  test: /\.(jpe?g|png|gif|svg)$/i,
  loaders: ['file?hash=sha512&digest=hex&name=[path][hash].[ext]']
}

I doubt this is possible unless the file-loader lets you run arbitrary functions to format the file name.

{
  test: path.resolve("./images/test.png"),
  loader: "file?name=hello.test.png"
}

@sokra The project has multiple entry file,not just one.I want the built image name prefixs with its related entry file name?Can we make it?

Seems duplicate to #1381.
Interested in this issue too, though.

recursive issue references here #1381 is pointing back to this one each citing a duplicate of the other :)

Finally, guys, is there a way to get entry point name in a custom loader?

[FuriouZz]

The only way, I found was to explore the reasons of the module directly in the loader.

var findEntry = function( mod ) {
  if (mod.reasons.length > 0) {
    return findEntry( mod.reasons[0].module )
  }
  return mod.resource
}

module.exports = function MyLoader() {
  var entry = findEntry( this._module )
  ...
}

Thanks FuriouZz, here's a small modification to make it work with HMR as well:

function findEntry(mod) {
    if (mod.reasons.length > 0 && mod.reasons[0].module.resource) {
        return findEntry(mod.reasons[0].module)
    }
    return mod.resource;
}
