class StringLike str => Matchable str where

An extention of string-like types for sub-string matching at various postions.

Minimal complete definition

matchesPrefixOf, matchesInfixOf, matchesSuffixOf, matchesWordOf

Methods

matchesExactly :: str -> str -> Bool

Checks if two strings match exactly. This should by equal to '(==)' for most types.

matchesPrefixOf :: str -> str -> Bool

Checks if the first string is a prefix of of the second. If the first string is empty, the result is always False.

matchesInfixOf :: str -> str -> Bool

Checks if the first string is an infix of the second, i.e. if the first string appears somewhere in the second. If the first string is empty, the result is always False.

matchesSuffixOf :: str -> str -> Bool

Checks if the first string is a suffix of the second. If the first string is empty, the result is always False.

matchesWordOf :: str -> str -> Bool

Checks if the first string matches any of the whitespace-separated substrings in the second string exactly. If the first string is empty, the result is always False.
