> Pass two numbers, get a regex-compatible source string for matching ranges. Validated against more than 2.78 million test assertions.
|

Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
|
||||
|
||||
## Install
|
||||
|
||||
Install with [npm](https://www.npmjs.com/):
|
||||
|
||||
```sh
|
||||
$ npm install --save to-regex-range
|
||||
```
|
||||
|
||||
<details>
|
||||
<summary><strong>What does this do?</strong></summary>
|
||||
|
||||
<br>
|
||||
|
||||
This libary generates the `source` string to be passed to `new RegExp()` for matching a range of numbers.
|
||||
|
||||
**Example**
|
||||
|
||||
```js
|
||||
const toRegexRange = require('to-regex-range');
|
||||
const regex = new RegExp(toRegexRange('15', '95'));
|
||||
```
|
||||
|
||||
A string is returned so that you can do whatever you need with it before passing it to `new RegExp()` (like adding `^` or `$` boundaries, defining flags, or combining it another string).

<summary><strong>Why use this library?</strong></summary>
|
||||
|
||||
<br>
|
||||
|
||||
### Convenience
|
||||
|
||||
Creating regular expressions for matching numbers gets deceptively complicated pretty fast.
|
||||
|
||||
For example, let's say you need a validation regex for matching part of a user-id, postal code, social security number, tax id, etc:
|
||||
|
||||
* regex for matching `1` => `/1/` (easy enough)
|
||||
* regex for matching `1` through `5` => `/[1-5]/` (not bad...)
|
||||
* regex for matching `1` or `5` => `/(1|5)/` (still easy...)
|
||||
* regex for matching `1` through `50` => `/([1-9]|[1-4][0-9]|50)/` (uh-oh...)
|
||||
* regex for matching `1` through `55` => `/([1-9]|[1-4][0-9]|5[0-5])/` (no prob, I can do this...)
|
||||
* regex for matching `1` through `555` => `/([1-9]|[1-9][0-9]|[1-4][0-9]{2}|5[0-4][0-9]|55[0-5])/` (maybe not...)
|
||||
* regex for matching `0001` through `5555` => `/(0{3}[1-9]|0{2}[1-9][0-9]|0[1-9][0-9]{2}|[1-4][0-9]{3}|5[0-4][0-9]{2}|55[0-4][0-9]|555[0-5])/` (okay, I get the point!)
|
||||
|
||||
The numbers are contrived, but they're also really basic. In the real world you might need to generate a regex on-the-fly for validation.
|
||||
|
||||
**Learn more**
|
||||
|
||||
If you're interested in learning more about [character classes](http://www.regular-expressions.info/charclass.html) and other regex features, I personally have always found [regular-expressions.info](http://www.regular-expressions.info/charclass.html) to be pretty useful.
|
||||
|
||||
### Heavily tested
|
||||
|
||||
As of April 07, 2019, this library runs [>1m test assertions](./test/test.js) against generated regex-ranges to provide brute-force verification that results are correct.
|
||||
|
||||
Tests run in ~280ms on my MacBook Pro, 2.5 GHz Intel Core i7.
|
||||
|
||||
### Optimized
|
||||
|
||||
Generated regular expressions are optimized:
|
||||
|
||||
* duplicate sequences and character classes are reduced using quantifiers
|
||||
* smart enough to use `?` conditionals when number(s) or range(s) can be positive or negative
|
||||
* uses fragment caching to avoid processing the same exact string more than once

|
||||
## Usage
|
||||
|
||||
Add this library to your javascript application with the following line of code
|
||||
|
||||
```js
|
||||
const toRegexRange = require('to-regex-range');
|
||||
```
|
||||
|
||||
The main export is a function that takes two integers: the `min` value and `max` value (formatted as strings or numbers).
|
||||
|
||||
```js
|
||||
const source = toRegexRange('15', '95');
|
||||
//=> 1[5-9]|[2-8][0-9]|9[0-5]
|
||||
|
||||
const regex = new RegExp(`^${source}$`);
|
||||
console.log(regex.test('14')); //=> false
|
||||
console.log(regex.test('50')); //=> true
|
||||
console.log(regex.test('94')); //=> true
|
||||
console.log(regex.test('96')); //=> false
|
||||
```
|
||||
|
||||
## Options
|
||||
|
||||
### options.capture
|
||||
|
||||
**Type**: `boolean`
|
||||
|
||||
**Deafault**: `undefined`
|
||||
|
||||
Wrap the returned value in parentheses when there is more than one regex condition. Useful when you're dynamically generating ranges.
|
||||
|
||||
```js
|
||||
console.log(toRegexRange('-10', '10'));
|
||||
//=> -[1-9]|-?10|[0-9]
|
||||
|
||||
console.log(toRegexRange('-10', '10', { capture: true }));
|
||||
//=> (-[1-9]|-?10|[0-9])
|
||||
```
|
||||
|
||||
### options.shorthand
|
||||
|
||||
**Type**: `boolean`
|
||||
|
||||
**Deafault**: `undefined`
|
||||
|
||||
Use the regex shorthand for `[0-9]`:
|
||||
|
||||
```js
|
||||
console.log(toRegexRange('0', '999999'));
|
||||
//=> [0-9]|[1-9][0-9]{1,5}
|
||||
|
||||
console.log(toRegexRange('0', '999999', { shorthand: true }));
|
||||
//=> \d|[1-9]\d{1,5}
|
||||
```
|
||||
|
||||
### options.relaxZeros
|
||||
|
||||
**Type**: `boolean`
|
||||
|
||||
**Default**: `true`
|
||||
|
||||
This option relaxes matching for leading zeros when when ranges are zero-padded.
|
||||
|
||||
```js
|
||||
const source = toRegexRange('-0010', '0010');
|
||||
const regex = new RegExp(`^${source}$`);
|
||||
console.log(regex.test('-10')); //=> true
|
||||
console.log(regex.test('-010')); //=> true
|
||||
console.log(regex.test('-0010')); //=> true
|
||||
console.log(regex.test('10')); //=> true
|
||||
console.log(regex.test('010')); //=> true
|
||||
console.log(regex.test('0010')); //=> true
|
||||
```
|
||||
|
||||
When `relaxZeros` is false, matching is strict:
|
||||
|
||||
```js
|
||||
const source = toRegexRange('-0010', '0010', { relaxZeros: false });
|
||||
const regex = new RegExp(`^${source}$`);
|
||||
console.log(regex.test('-10')); //=> false
|
||||
console.log(regex.test('-010')); //=> false
|
||||
console.log(regex.test('-0010')); //=> true
|
||||
console.log(regex.test('10')); //=> false
|
||||
console.log(regex.test('010')); //=> false
|
||||
console.log(regex.test('0010')); //=> true
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Heads up!
|
||||
|
||||
**Order of arguments**
|
||||
|
||||
When the `min` is larger than the `max`, values will be flipped to create a valid range:
|
||||
|
||||
```js
|
||||
toRegexRange('51', '29');
|
||||
```
|
||||
|
||||
Is effectively flipped to:
|
||||
|
||||
```js
|
||||
toRegexRange('29', '51');
|
||||
//=> 29|[3-4][0-9]|5[0-1]
|
||||
```
|
||||
|
||||
**Steps / increments**
|
||||
|
||||
This library does not support steps (increments). A pr to add support would be welcome.
|
||||
|
||||
## History
|
||||
|
||||
### v2.0.0 - 2017-04-21
|
||||
|
||||
**New features**
|
||||
|
||||
Adds support for zero-padding!
|
||||
|
||||
### v1.0.0
|
||||
|
||||
**Optimizations**
|
||||
|
||||
Repeating ranges are now grouped using quantifiers. rocessing time is roughly the same, but the generated regex is much smaller, which should result in faster matching.
