Wildcards is a pattern matching unit for Lazarus/Free Pascal. It provides a Match function to match a pattern against a string. If the pattern must be matched against several strings the unit provides a TWildcard class that is more efficient. Patterns may contain ?, *, [a-z] and other constructions (see Pattern Format).

Example

patmatch.pas
program PatMatch;

{$mode objfpc}{$H+}

uses Classes, SysUtils, Wildcrds;

procedure DoMatch(const Pattern, S: String);
begin
  WriteLn('Match(''', Pattern, ''' , ''', S, ''') => ', Match(Pattern, S));
end;

begin
  DoMatch('p????l', 'pascal');
  DoMatch('p????l', 'free pascal');

  DoMatch('h*', 'hello');
  DoMatch('h*', 'Hello');

  DoMatch('[Ff]ree [Pp]ascal \D.\D.\D', 'Free Pascal 2.6.4');
  DoMatch('[Ff]ree [Pp]ascal \D.\D.\D', 'free pascal 2.6.4b');
  DoMatch('[Ff]ree [Pp]ascal \D.\D.\D', 'free pascal 2.6.4');
end.

To run this program use :

user$ fpc patmatch
user$ ./patmatch

The result should be :

Match('p????l' , 'pascal') => TRUE
Match('p????l' , 'free pascal') => FALSE
Match('h*' , 'hello') => TRUE
Match('h*' , 'Hello') => FALSE
Match('[Ff]ree [Pp]ascal \D.\D.\D' , 'Free Pascal 2.6.4') => TRUE
Match('[Ff]ree [Pp]ascal \D.\D.\D' , 'free pascal 2.6.4b') => FALSE
Match('[Ff]ree [Pp]ascal \D.\D.\D' , 'free pascal 2.6.4') => TRUE
