Incorrect asset name when entry point name contains [hash]

[kendrickw]

Expected Behavior

Given the rollup config:

// rollup.config.js
export default {
  input: {
     'dash-entry': 'src/entry.js'
  },
  plugins: [
    modularCss(),
    ...
  ],
  output: {
     entryFileNames: '[name].[hash].js',
     assetFileNames: '[name].[hash][extname]'
  },
};

Expect the generated css name to be dash-entry.abababab.css.

Current Behavior

The generated css name is entry.abababab.css (missing dash-).
If I remove the [hash] from entryFileNames, then everything works as expected.
Also, if the input name doesn't have a '-', then the asset name is correctly generated as well.

Your Environment

Executable	Version
modular-css	21.1.1

OS	Version
macOS Sierra	10.14.2

Almost certainly a bug in here:

modular-css/packages/rollup/parser.js

Line 13 in 7655d72

[ "name", "(?<name>\\w+)" ],

Unfortunately I still don't think there's an easier way to get that info, so I'll have to add a failing test and work backwards.

Maybe something like this:

[ "name",     "(?<name>[\\w\\-. ]+)" ],

?

Working on a change to how assets are chunked/named that sidesteps this problem by naming them after the CSS file, not the JS entry file. It's just too painful to try and figure out with the info rollup currently gives me.

Working on that over here, almost done: https://github.com/tivac/modular-css/tree/corrected-chunking
