+# detect-indent [![Build Status](https://travis-ci.org/sindresorhus/detect-indent.svg?branch=master)](https://travis-ci.org/sindresorhus/detect-indent)
+
+> Detect the indentation of code
+
+Pass in a string of any kind of text and get the indentation.
+
+
+## Use cases
+
+- Persisting the indentation when modifying a file.
+- Have new content match the existing indentation.
+- Setting the right indentation in your editor.
+
+
+## Install
+
+```
+$ npm install --save detect-indent
+```
+
+
+## Usage
+
+Here we modify a JSON file while persisting the indentation:
+
+```js
+const fs = require('fs');
+const detectIndent = require('detect-indent');
+
+/*
+{
+    "ilove": "pizza"
+}
+*/
+const file = fs.readFileSync('foo.json', 'utf8');
+
+// tries to detect the indentation and falls back to a default if it can't
+const indent = detectIndent(file).indent || '    ';
+
+const json = JSON.parse(file);
+
+json.ilove = 'unicorns';
+
+fs.writeFileSync('foo.json', JSON.stringify(json, null, indent));
+/*
+{
+    "ilove": "unicorns"
+}
+*/
+```
+
+
+## API
+
+Accepts a string and returns an object with stats about the indentation:
+
+* `amount` {number} - Amount of indentation, for example `2`
+* `type` {string|null} - Type of indentation. Possible values are `tab`, `space` or `null` if no indentation is detected
+* `indent` {string} - Actual indentation
+
+
+## Algorithm
+
+The current algorithm looks for the most common difference between two consecutive non-empty lines.
+
+In the following example, even if the 4-space indentation is used 3 times whereas the 2-space one is used 2 times, it is detected as less used because there were only 2 differences with this value instead of 4 for the 2-space indentation:
+
+```css
+html {
+  box-sizing: border-box;
+}
+
+body {
+  background: gray;
+}
+
+p {
+    line-height: 1.3em;
+    margin-top: 1em;
+    text-indent: 2em;
+}
+```
+
+[Source.](https://medium.com/@heatherarthur/detecting-code-indentation-eff3ed0fb56b#3918)
+
+Furthermore, if there are more than one most used difference, the indentation with the most lines is selected.
+
+In the following example, the indentation is detected as 4-spaces:
+
+```css
+body {
+  background: gray;
+}
+
+p {
+    line-height: 1.3em;
+    margin-top: 1em;
+    text-indent: 2em;
+}
+```
