+# nth-check [![Build Status](https://travis-ci.org/fb55/nth-check.svg)](https://travis-ci.org/fb55/nth-check)
+
+Parses and compiles CSS nth-checks to highly optimized functions.
+
+### About
+
+This module can be used to parse & compile nth-checks, as they are found in CSS 3's `nth-child()` and `nth-last-of-type()`. It can be used to check if a given index matches a given nth-rule, or to generate a sequence of indices matching a given nth-rule.
+
+`nth-check` focusses on speed, providing optimized functions for different kinds of nth-child formulas, while still following the [spec](http://www.w3.org/TR/css3-selectors/#nth-child-pseudo).
+
+### API
+
+```js
+import nthCheck, { parse, compile } from "nth-check";
+```
+
+##### `nthCheck(formula)`
+
+Parses and compiles a formula to a highly optimized function. Combination of `parse` and `compile`.
+
+If the formula doesn't match any elements, it returns [`boolbase`](https://github.com/fb55/boolbase)'s `falseFunc`. Otherwise, a function accepting an _index_ is returned, which returns whether or not the passed _index_ matches the formula.
+
+**Note**: The nth-rule starts counting at `1`, the returned function at `0`.
+
+**Example:**
+
+```js
+const check = nthCheck("2n+3");
+
+check(0); // `false`
+check(1); // `false`
+check(2); // `true`
+check(3); // `false`
+check(4); // `true`
+check(5); // `false`
+check(6); // `true`
+```
+
+##### `parse(formula)`
+
+Parses the expression, throws an `Error` if it fails. Otherwise, returns an array containing the integer step size and the integer offset of the nth rule.
+
+**Example:**
+
+```js
+parse("2n+3"); // [2, 3]
+```
+
+##### `compile([a, b])`
+
+Takes an array with two elements (as returned by `.parse`) and returns a highly optimized function.
+
+**Example:**
+
+```js
+const check = compile([2, 3]);
+
+check(0); // `false`
+check(1); // `false`
+check(2); // `true`
+check(3); // `false`
+check(4); // `true`
+check(5); // `false`
+check(6); // `true`
+```
+
+##### `generate([a, b])`
+
+Returns a function that produces a monotonously increasing sequence of indices.
+
+If the sequence has an end, the returned function will return `null` after the last index in the sequence.
+
+**Example:** An always increasing sequence
+
+```js
+const gen = nthCheck.generate([2, 3]);
+
+gen(); // `1`
+gen(); // `3`
+gen(); // `5`
+gen(); // `8`
+gen(); // `11`
+```
+
+**Example:** With an end value
+
+```js
+const gen = nthCheck.generate([-2, 5]);
+
+gen(); // 0
+gen(); // 2
+gen(); // 4
+gen(); // null
+```
+
+##### `sequence(formula)`
+
+Parses and compiles a formula to a generator that produces a sequence of indices. Combination of `parse` and `generate`.
+
+**Example:** An always increasing sequence
+
+```js
+const gen = nthCheck.sequence("2n+3");
+
+gen(); // `1`
+gen(); // `3`
+gen(); // `5`
+gen(); // `8`
+gen(); // `11`
+```
+
+**Example:** With an end value
+
+```js
+const gen = nthCheck.sequence("-2n+5");
+
+gen(); // 0
+gen(); // 2
+gen(); // 4
+gen(); // null
+```
