It resolves `[name]` and `[contenthash]` just fine, but doesn't know how to deal with `[path]`.\r\n\r\n\r\nI'm using a plugin to dynamically inject options into loaders to configure bare loader URLs such as\r\n```js\r\nimport worker from \"workerize-loader!./path-to/worker\"\r\n```\r\n\r\ncentrally, and luckily I was able to extend the logic there to use the current compilation context and module context to compute a relative path, but yeah... _this_ is not very ergonomic, easily understood or maintainable:\r\n\r\n```js\r\nnew InjectOptionsPlugin({\r\n  loaders : {\r\n    \"workerize-loader\" : ( module, compilation ) =\u003e {\r\n      const context = path\r\n        .relative( compilation.options.context, module.context );\r\n        .replace( /\\\\/g, \"/\" );\r\n        \r\n      return {\r\n        name : dev ? `${context}[name]` : \"${context}[name].[contenthash]`\r\n      };\r\n    }\r\n  }\r\n})\r\n```\r\n\r\ncompared to what it _used_ to be:\r\n\r\n```js\r\nnew InjectOptionsPlugin({\r\n  loaders : {\r\n    \"workerize-loader\" : {\r\n      name : dev ? \"[path][name]\" : \"[path][name].[contenthash]\"\r\n    }\r\n  }\r\n})\r\n```","author":{"url":"https://github.com/rjgotten","@type":"Person","name":"rjgotten"},"datePublished":"2022-09-12T10:21:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/130/workerize-loader/issues/130"}
