spaceCase\n\n```js\n// default:\ndotNotation('$catDog') === 'cat.Dog'\n// force lower case:\ndotNotation('$catDog').toLowerCase() === 'cat.dog'\n```\n\n### Strings with spaces\n\nAs soon as there is a space in the target string, it will regard the input as a _sentence_ and only split each part at the spaces.\n\n| Name                              | Input example

shortcuts\n\nWith [Better Touch Tool](https://folivora.ai) you can set up keyboard shortcuts to convert selected text with JavaScript. This repo provides an easy to install preset that has shortcuts for pascal, kebab and camel case! (thanks to [@AndrewKoch](https://github.com/AndrewKoch)) It even supports multi-cursors in VSCode!\n\nHere is an example triggering keyboard shortcuts to convert the selected text to PascalCase; kebab-case; camelCase:\n\n![keyboard shortcuts example](.media/case-anything_VSCode.gif?raw=true)\n\nYou can download the BTT preset from the source code: [case-anything.bttpreset](case-anything.bttpreset).\n\n## Package size\n\nWe'll compare this package with [blakeembrey/change-case](https://github.com/blakeembrey/change-case), a very famous package on npm.\n\n|              | case-anything | change-case  |\n| ------------ | ------------- | ------------ |\n| camelCase    | 1.1K (572)    | 27.2K (6K)   |\n| pascalCase   | 1.1K (561)    | 27.4K (6.1K) |\n| kebabCase    | 1.1K (541)    | 26.8K (5.9K) |\n| snakeCase    | 1.1K (540)    | 26.8K (5.9K) |\n| constantCase | 1.1K (540)    | 27.2K (6K)   |\n| pathCase     | 1K (530)      | 26.8K (5.9K) |\n\n## Source code\n\nWhat keeps my package small, is that literally just uses a regex to separate \"words\".\n\n```js\n// the source code is similar to:\nexport function splitOnSpecialChars(string: string): any[] {\n  return string.match(/^[a-z]+|[A-Z][a-z]+|[a-z]+|[0-9]+|[A-Z]+(?![a-z])/g)\n}\n```\n\nThe actual regex used is a little bit more comprehensive and can be found [here](https://github.com/mesqueeb/case-anything/blob/production/src/utils.ts#L7).\n\n## Meet the family (more tiny utils with TS support)\n\n- [is-what 🙉](https://github.com/mesqueeb/is-what)\n- [is-where 🙈](https://github.com/mesqueeb/is-where)\n- [merge-anything 🥡](https://github.com/mesqueeb/merge-anything)\n- [check-anything 👁](https://github.com/mesqueeb/check-anything)\n- [remove-anything ✂️](https://github.com/mesqueeb/remove-anything)\n- [getorset-anything 🐊](https://github.com/mesqueeb/getorset-anything)\n- [map-anything 🗺](https://github.com/mesqueeb/map-anything)\n- [filter-anything ⚔️](https://github.com/mesqueeb/filter-anything)\n- [copy-anything 🎭](https://github.com/mesqueeb/copy-anything)\n- [case-anything 🐫](https://github.com/mesqueeb/case-anything)\n- [flatten-anything 🏏](https://github.com/mesqueeb/flatten-anything)\n- [nestify-anything 🧅](https://github.com/mesqueeb/nestify-anything)\n","funding_links":["https://github.com/sponsors/mesqueeb"],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmesqueeb%2Fcase-anything","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmesqueeb%2Fcase-anything","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmesqueeb%2Fcase-anything/lists"}
