Hello,
i want to dynamically create a regular expression from an input string. However i only want a small subset of expressions to be treated as such. Most of the input shall be treated as literal (e.g. dots '.' shall actually be treated as dots and not wildcards)
Is there a way to escape a whole group/substring when defining a regexp, or is the only way to escape all special chars, except the ones i want to keep, manually. If i need to escape everything manually, is there a syntax/keyword which gets me all special chars in the string so i can escape all of them?
Example (dots shall be treated as literal dots):
>> r = myfun('a.b.c','a.b.')
r = 1
>> r_myfun('aXb.c','a.b.')
r = []
