Leading _ in exported classname

[Diokuz]

bug

What is the current behavior?

:export {
  ._x { color: red }
}

transformed to object

exports.locals = {
	"x": "src⁄x___x"
};

If the current behavior is a bug, please provide the steps to reproduce.
just use [css-loader, postcss-loader] with this postcss.config.js:

const plugins = [
  require('postcss-modules-local-by-default'),
  require('postcss-modules-scope')(),
];

exports.plugins = plugins;

What is the expected behavior?
should be

exports.locals = {
	"_x": "src⁄x___x"
};

Please mention other relevant information such as your webpack version, Node.js version and Operating System.

node@7 webpack@2 css-loader@0.28.2

Looks like you cannot take just prop here, because of this

@Diokuz interesting, _x is valid ident for css-modules, maybe we need question about this here https://github.com/css-modules/postcss-modules-values

[michael-ciniawsky]

You use postcss-modules-* plugins in postcss.config.js + postcss-loader ?

[michael-ciniawsky]

That could be a problem then, since css-loader implements CSSM via these plugins and if the source CSS is already transformed this might not work

[TrySound]

@michael-ciniawsky We can fix that :)

[michael-ciniawsky]

@TrySound We should fix that 😛 once and for all, always problems 🐛 atm... :D

[michael-ciniawsky]

@Diokuz Does it work without the plugins in postcss.config.js ?

[alexander-akait]

@TrySound Am i right what we should fix this in postcss-modules-values?

[Diokuz]

You use postcss-modules-* plugins in postcss-config.js + postcss-loader ?

Yes, postcss-loader then css-loader

@Diokuz Does it work without the plugin in postcss.config.js ?

Without plugins it creates not what I need

/***/ "./src/x.css":
/***/ (function(module, exports, __webpack_require__) {

exports = module.exports = __webpack_require__("./node_modules/css-loader/lib/css-base.js")(undefined);
// imports


// module
exports.push([module.i, "._x {\n  color: red;\n}\n", ""]);
