About stdlib...
</summary>
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
reEOL
[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]
[Regular expression][mdn-regexp] to match a [newline][newline] character sequence.
bash
npm install @stdlib/regexp-eol
javascript
var reEOL = require( '@stdlib/regexp-eol' );
#### reEOL( [options] )
Returns a [Regular expression][mdn-regexp] to match a [newline][newline] character sequence.
javascript
var RE_EOL = reEOL();
var bool = RE_EOL.test( '\n' );
// returns true
bool = RE_EOL.test( '\r\n' );
// returns true
bool = RE_EOL.test( '\\r\\n' );
// returns false
The function accepts an options object with optional properties:
- flags: string specifying regular expression [flags][mdn-regexp-flags]. Default: ''.
- capture: boolean indicating whether to create a capture group for the match. Default: false.
By default, the function returns a regular expression which does not have any flags specified. To specify [flags][mdn-regexp-flags], set the flags option with a list of flags (which may be in any order).
javascript
var replace = require( '@stdlib/string-replace' );
var RE_EOL = reEOL({
'flags': 'g'
});
var str = '1\n2\n3';
var out = replace( str, RE_EOL, '' );
// returns '123'
By default, the function returns a regular expression which does not capture the part of a string matching the regular expression. To capture matches, set the capture option.
javascript
var RE_EOL = reEOL({
'capture': true
});
var str = 'beep\nboop';
var arr = str.split( RE_EOL );
// returns [ 'beep', '\n', 'boop' ]
#### reEOL.REGEXP
[Regular expression][mdn-regexp] to match a [newline][newline] character sequence.
javascript
var bool = reEOL.REGEXP.test( 'abc' );
// returns false
#### reEOL.REGEXP_CAPTURE
[Regular expression][mdn-regexp] to capture a [newline][newline] character sequence.
javascript
var parts = reEOL.REGEXP_CAPTURE.exec( '\n' );
// returns [ '\n', '\n' ]
javascript
var reEOL = require( '@stdlib/regexp-eol' );
var RE_EOL = reEOL();
var bool;
var str;
bool = RE_EOL.test( '\r\n' );
// returns true
bool = RE_EOL.test( '\n' );
// returns true
bool = RE_EOL.test( '\r' );
// returns false
bool = RE_EOL.test( '\\r\\n' );
// returns false
bool = RE_EOL.test( 'beep' );
// returns false
str = 'This is\na newline\r\ndelimited string.';
var arr = str.split( RE_EOL );
// returns [ 'This is', 'a newline', 'delimited string.' ]
