Modifiers

`addModifier`

Manually add a regex modifier (flag).

Parameter	Expected type	Description
`value`	`String`	Modifier to add

let expr = VerEx()
console.log(expr.flags); // => 'gm'

expr = expr.addModifier('i');
console.log(expr.flags); // => 'gim'

`removeModifier`

Manually remove a regex modifier (flag).

Parameter	Expected type	Description
`value`	`String`	Modifier to remove

let expr = VerEx();
console.log(expr.flags); // => 'gm'

expr = expr.removeModifier('m');
console.log(expr.flags); // => 'g'

`withAnyCase`

Control case-insensitive matching. Equivalent to adding or removing the i modifier.

Parameter	Expected type	Description
`enable` (defaults to `true`)	`boolean`	Whether to enable this behavior

const hexColorCode = VerEx()
    .find('#')
    .range('0', '9', 'a', 'f')
    .repeatPrevious(6)
    .withAnyCase();

console.log(hexColorCode.test('#93afee')); // => true
hexColorCode.lastIndex = 0;
console.log(hexColorCode.test('#93AFEE')); // => true

`stopAtFirst`

Control global matching. Enabling would cause the expression to not look for matches beyond the first match. Equivalent to removing or adding the g modifier. Global matching is enabled by default.

Parameter	Expected type	Description
`enable` (defaults to `true`)	`boolean`	Whether to enable this behavior

`searchOneLine`

Control multi-line matching. Enabling would cause the expression to not look for matches beyond the first line. Equivalent to removing or adding the m modifier. Multi-line matching is enabled by default.

Parameter	Expected type	Description
`enable` (defaults to `true`)	`boolean`	Whether to enable this behavior

let findFoo = VerEx().startOfLine().find('foo').endOfLine();
console.log(findFoo.test('foo\nfoo\nfoo')); // => true

findFoo = findFoo.searchOneLine();
console.log(findFoo.test('foo\nfoo\nfoo')); // => false

`repeatPrevious`

Usage 1

Repeat the previous item exactly count times.

Parameter	Expected type	Description
`count`	`Number`	Number of times to repeat the previous item

const expr = VerEx()
    .startOfLine()
    .find('foo')
    .repeatPrevious(2)
    .endOfLine();

console.log(expr.test('foofoo')); // => true
expr.lastIndex = 0;
console.log(expr.test('foofoofoo')); // => false

Usage 2

Repeat the previous item between mix and max (inclusive) times.

Parameter	Expected type	Description
`min`	`Number`	Minimum number of times to repeat the previous item
`max`	`Number`	Maximum number of times to repeat the previous item

const expr = VerEx()
    .startOfLine()
    .find('foo')
    .repeatPrevious(1, 3)
    .endOfLine();

console.log(expr.test('foo')); // => true
expr.lastIndex = 0;
console.log(expr.test('foofoo')); // => true
expr.lastIndex = 0;
console.log(expr.test('foofoofoo')); // => true
expr.lastIndex = 0;
console.log(expr.test('foofoofoofoo')); // => false
