Grouping

.group

Creates a non-capturing group of the proceeding elements. Needs to be finalised with .end().

Example

ExpressiveRegex()\
    .group\
        .range('a', 'f')\
        .range('0', '9')\
        .string('XXX')\
    .end()\
.toRegexString()

([a-f][0-9]XXX)

.capture

Creates a capture group for the proceeding elements. Needs to be finalised with .end().

Example

ExpressiveRegex()\
    .capture\
        .range('a', 'f')\
        .range('0', '9')\
        .string('XXX')\
    .end()\
.toRegexString()

([a-f][0-9]XXX)

.setOfLiterals

Creates a set from the proceeding elements. Needs to be finalised with .end(). Inside this statement only is allowed Literals except anyChar, .rawChar, .string, .rawString, .anythingButRange, .anythingButChars

Example

ExpressiveRegex()\
    .setOfLiterals\
        .char('-')\
        .range(1,4)\
        .anyOfChars('dfs')\
    .end()\
.toRegexString()

"[\-1-4dfs]"

.end()

Signifies the end of a ExpressiveRegex grouping.

Example

ExpressiveRegex()
    .capture\
        .setOfLiterals\
            .char('-')\
            .range(1,4)\
            .anyOfChars('dfs')\
        .end()\
        .range('0', '9')\
        .string('XXX')\
    .end()\
.toRegexString()

([\-1-4dfs][0-9]XXX)
