That `plugin` function is passed with `(line, info, index)` signature, where `line` is string representing the stacktrace line, and `info` is an object with `.line`, `.column` and `.filename` properties. That's useful, you can attach them to some error object.\n\n_Meant to be used inside `mapper` of the [clean-stacktrace][],\nanother useful mapper is [clean-stacktrace-relative-paths][] to show\nrelative paths inside stacktrace, instead of absolute paths._\n\n**Params**\n\n* `plugin` **{Function}**: A function passed with `(line, info, index)` signature.    \n* `returns` **{Function}** `mapper`: Function that can be passed to [clean-stacktrace][]  \n\n**Example**\n\n```js\nconst metadata = require('clean-stacktrace-metadata')\nconst cleanStack = require('clean-stacktrace')\n\nconst err = new Error('Missing unicorn')\nconsole.log(error.stack)\n// =\u003e\n// Error: Missing unicorn\n//     at quxie (/home/charlike/apps/alwa.js:8:10)\n//     at module.exports (/home/charlike/apps/foo.js:6:3)\n//     at Object.\u003canonymous\u003e (/home/charlike/apps/dush.js:45:3)\n//     at Module._compile (module.js:409:26)\n//     at Object.Module._extensions..js (module.js:416:10)\n//     at Module.load (module.js:343:32)\n//     at Function.Module._load (module.js:300:12)\n//     at Function.Module.runMain (module.js:441:10)\n//     at startup (node.js:139:18)\n\nconst mapper = metadata((line, info, index) =\u003e {\n  if (index === 1) {\n    err.line = info.line\n    err.column = info.column\n    err.filename = info.filename\n    err.place = info.place\n  }\n\n  return line\n})\n\nconst stack = cleanStack(error.stack, mapper)\nconsole.log(stack)\n// =\u003e\n// Error: Missing unicorn\n//     at quxie (/home/charlike/apps/alwa.js:8:10)\n//     at module.exports (/home/charlike/apps/foo.js:6:3)\n//     at Object.\u003canonymous\u003e (/home/charlike/apps/dush.js:45:3)\n\nconsole.log(err.place) // =\u003e 'quxie'\nconsole.log(err.line) // =\u003e 8\nconsole.log(err.column) // =\u003e 10\nconsole.log(err.filename) // =\u003e '/home/charlike/apps/alwa.js'\n```\n\n## Related\n- [always-done](https://www.npmjs.com/package/always-done): Handle completion and errors with elegance!

For bugs and feature requests, [please create an issue](https://github.com/tunnckoCore/clean-stacktrace-metadata/issues/new).  \nPlease read the [contributing guidelines](CONTRIBUTING.md) for advice on opening issues, pull requests, and coding standards.  \nIf you need some help and can spent some cash, feel free to [contact me at CodeMentor.io](https://www.codementor.io/tunnckocore?utm_source=github\u0026utm_medium=button\u0026utm_term=tunnckocore\u0026utm_campaign=github) too.\n\n**In short:** If you want to contribute to that project, please follow these things\n\n1. Please DO NOT edit [README.md](README.md), [CHANGELOG.md](CHANGELOG.md) and [.verb.md](.verb.md) files. See [\"Building docs\"](#building-docs) section.\n2. Ensure anything is okey by installing the dependencies and run the tests. See [\"Running tests\"](#running-tests) section.\n3. Always use `npm run commit` to commit changes instead of `git commit`, because it is interactive and user-friendly. It uses [commitizen][] behind the scenes, which follows Conventional Changelog idealogy.\n4. Do NOT bump the version in package.json. For that we use `npm run release`, which is [standard-version][] and follows Conventional Changelog idealogy.\n\nThanks a lot! :)\n\n## Building docs\nDocumentation and that readme is generated using [verb-generate-readme][], which is a [verb][] generator, so you need to install both of them and then run `verb` command like that\n\n```\n$ npm install verbose/verb#dev verb-generate-readme --global \u0026\u0026 verb\n```\n\n_Please don't edit the README directly. Any changes to the readme must be made in [.verb.md](.verb.md)._\n\n## Running tests\nClone repository and run the following in that cloned directory\n\n```\n$ npm install \u0026\u0026 npm test\n```\n\n## Author\n**Charlike Mike Reagent**\n\n+ [github/tunnckoCore](https://github.com/tunnckoCore)\n+ [twitter/tunnckoCore](https://twitter.com/tunnckoCore)\n+ [codementor/tunnckoCore](https://codementor.io/tunnckoCore)\n\n## License\nCopyright © 2017, [Charlike Mike Reagent](https://i.am.charlike.online).
