6fb266e0d2Refactored isNormalChar(), wrote function to get special characters that have metachar replacementsAadhavan Srinivasan2025-01-24 15:49:33 -0500
649485f01dRemoved character range creation from the first part of shuntingYard() (the part that adds concatenation operators), because octal and hex values haven't yet been deciphered at this point in the codeAadhavan Srinivasan2025-01-22 16:51:00 -0500
25cb79f01bChanged the value of EPSILON, so that we can use the NUL character (which it used to be) in a regex; Also added code to detect escaped backslashesAadhavan Srinivasan2025-01-21 22:10:07 -0500
