auto-format\n\n[![Build Status](https://travis-ci.org/jundl77/auto-format.svg?branch=master)](https://travis-ci.org/jundl77/auto-format)\n[![Coverage Status](https://coveralls.io/repos/github/jundl77/auto-format/badge.svg?branch=master)](https://coveralls.io/github/jundl77/auto-format?branch=master)\n[![npm](http://img.shields.io/npm/v/auto-format.svg?style=flat)](https://www.npmjs.com/package/auto-format)\n[![Document](https://img.shields.io/badge/docs-latest-brightgreen.svg?style=flat)](https://jundl77.github.io/auto-format/)\n\nAn easy to use, light-weight library to auto-format code in javascript. Works well with code highlighting libraries to display beautiful, uniformly formatted code. \n\nAs of right now only Java can be formatted properly, although you will probably get decent results with any language that uses brackets as scope delimiters. Furthermore, the library is very extensible, in fact you only have to implement 5 methods to add support for another language.\nPlease see [contribute](#contribute) if you would like to contribute. Help is always welcome!\n\n## Examples\n*format* method:\n![](https://raw.githubusercontent.com/jundl77/auto-format/readme/images/af-format.gif)\n\nYou can also check out https://exemplator.xyz where all code samples are formatted\nwith this library.\n\n[Live example](https://runkit.com/jundl77/auto-format.format) of *format* method.\n\n## Install\n\nRun ` npm install auto-format --save`\n\n## Usage\n\nAs of right now, only Java is fully supported.\n\nES6: \n```es6 \nimport Formatter from \"auto-format\"\n```\nVanilla JS: \n\n```js \nvar Formatter = require('auto-format');\n```\n***\n\n#### Simple example: *format*\n\n```js\nvar indentToken = \"   \";\nvar unformattedCode = \"code to format\";\n\nvar javaFormatter = Formatter.createJavaFormatter(indentToken);\nvar formattedCode = javaFormatter.format(unformattedCode);\n```\nFormat a string of code. The string will be cut into lines and lines will \nbe indented accordingly to their scope.\n\n##### -- Parameters:\n`indentToken` : The token used to indent lines (e.g. 2 or 4 spaces).\n\n`unformattedCode` : A string of unformatted code (including line breaks).\n\n##### -- Return:\n`formattedCode` : An array lines of code. All lines will have been correctly\n                  indented according to their scope.\n                  \n***\n\n#### Complex example: *formatSnippet*\n\n```js\nvar indentToken = \"   \";\nvar javaFormatter = Formatter.createJavaFormatter(indentToken);\n\nvar unformattedCode = \"code to format\";\nvar selectionStartRow = 11;\nvar selectionEndRow = 11;\nvar snippetOffset = 6;\n\nvar formattedCode = javaFormatter.formatSnippet(unformattedCode, selectionStartRow, \n    selectionEndRow, snippetOffset);\n```\n\nA slight variation of ```format(codeString)```. Useful if you want to display a code snippet around a selection of lines like\n[here](https://exemplator.xyz).\n\nIn addition to indenting lines, formatSnippet takes a selection and an offset. \n\nThe selection consists of one or several lines which should be \"highlighted\" in the code. For example the line that you would like to show off. The offset defines the number of lines above and below the selection.\n\nThe start and end of the snippet is calculated from the selection start, end and the offset. `formatSnippet` intelligently cuts the snippet out of the original codebase. 'Intelligently' means the method\nalways tries to cut out only the method out of the selection. If the method is too big, only a part of the method will be cut out, but lines outside this method (i.e. other methods etc.) are cut away unless they comment that method.\n\n##### -- Parameters:\n`indentToken` : The token used to indent lines (e.g. 2 or 4 spaces).\n\n`unformattedCode` : A string of unformatted code (including line breaks).\n\n`selectionStartRow` : The start row of the selection in the code base.\n\n`selectionEndRow` : The end row of the selection in the code base.\n\n`snippetOffset` : The number of lines above and below the selection.\n\n##### -- Example:\n```\nSelection start row: 11\nSelection end row: 11\nOffset: 6 \n------------------------------\nSnippet start row: 11 - 6 = 5\nSnippet end row: 11 + 6 = 17\n```\n\n##### -- Return:\n`formattedCode` : An array in the form of\n```\n[code string above selection, code string of selection, code string below selection,\n[new start line of snippet in original file, new end line of snippet in original file]]\n```\n\nFor more details and examples see the [documentation](https://jundl77.github.io/auto-format/).\n\n## Contribute\n\nPull requests are always welcome. To add support for a new language, look at the [JavaFormatter](./src/formatters/javaFormatter.js).\n\nThe documentation is [here](https://jundl77.github.io/auto-format/).\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjundl77%2Fauto-format","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjundl77%2Fauto-format","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjundl77%2Fauto-format/lists"}
