An Objective-C library designed to enable regular expression based scanning.
Example Usage
TKScanner *scanner = [[TKScanner alloc] initWithString:@"This is a string"];
[scanner pos]; // Scanner position is 0
[scanner scan:@"\\w+"]; // Returns @"This"
[scanner scan:@"\\w+"]; // Returns nil
[scanner scan:@" "]; // Returns @" "
[scanner scan:@"\\w+"]; // Returns @"is"
[scanner scan:@" "]; // Returns @" "
[scanner eos]; // Returns NO
[scanner scan:@"a"]; // Returns @"a"
[scanner scan:@" "]; // Returns @" "
[scanner scan:@"string"]; // Returns @"a"
[scanner pos]; // Scanner position is 16
[scanner reset]; // Resets scanner to position 0
[scanner exists:@"string"] // Pattern exists somewhere in string
[scanner getch]; // Returns next character and adjusts pointer @"T"
[scanner scan_util:@"is"] // Scan until pattern is found
[scanner unscan] // Moves pointer back to previous pointer
[scanner peek]; // returns @" "
