regex-format

Format regex with string substitutions.

Example

regexFormat(/^Author:\s+{#name} <{#email}>$/, {
  name: 'someone',
  email: '[e-mail]'
})
//=> /^Author:\s+someone <someone@example\.com>$/
 
regexFormat(/^{}$/, 'foo$1')
//=> /^foo\$1$/

API

regexFormat(spec, [values]...)

spec is a RegExp, otherwise it is converted to RegExp. Flags are preserved.

The syntax for substitutions is the same as accepted by string-format, except that non-empty groups are prepended with a hash sign: {#0}, {#foo.bar}, etc (empty groups are still {}).

Install
