RegExp

Create a regular expression from a regular expression string.

Usage

var reFromString = require( '@stdlib/utils/regexp-from-string' );

reFromString( str )

Parses a regular expression string and returns a new regular expression.

var re = reFromString( '/beep/' );
// returns /beep/

Notes

• Provided strings must be properly escaped.

  // Unescaped:
  var re = reFromString( '/\w+/' );
  // returns /w+/
  
  // Escaped:
  re = reFromString( '/\\w+/' );
  // returns /\w+/
  

Examples

var reFromString = require( '@stdlib/utils/regexp-from-string' );

var re = reFromString( '/beep/' );
// returns /beep/

re = reFromString( '/[A-Z]*/' );
// returns /[A-Z]*/

re = reFromString( '/\\\\\\\//ig' );
// returns /\\\//gi

re = reFromString( '/[A-Z]{0,}/' );
// returns /[A-Z]{0,}/

re = reFromString( '/^boop$/' );
// returns /^boop$/

re = reFromString( '/(?:.*)/' );
// returns /(?:.*)/

re = reFromString( '/(?:beep|boop)/' );
// returns /(?:beep|boop)/

re = reFromString( '/\\w+/' );
