Regex challenge !

[Badgers]

Hi,

Any regex experts out there, been working on this, but wondering if anyone has idea to creating this...

A string value and return a boolean indicating if the string matches the pattern

The input can consist of the following values: a-z, \, _, %.

_ in the pattern represents any character
% represents 0 or more characters
\ can be used to escape the next character to take away any special meaning.


For example, patterns :
“a_c” matches “abc” but not “abcd”
“ab%d” matches “abdgdgdgd” or “abd” but not “abbbde”
“ab\%” matches “ab%” but not “abcd”
“__%” matches “ab” and “abcd” but not “a”

Thanks

“ab%d” matches “abdgdgdgd” or “abd” but not “abbbde”

% is '0 or more' characters but your example points to % indicating 1 or more characters exluding 1 or more of the SAME character.
