Simply send the message "goatWithSubstitutions:" to a template string, supplying an NSDictionary containing the substitution lists. e.g.: - NSDictionary *substitions = [NSDictionary dictionaryWithObjectsAndKeys: - [NSArray arrayWithObjects:@"fred", @"george", @"tom", nil], @"name", - [NSArray arrayWithObjects:@"a {desc} trailer", @"a slum", @"a {desc} bungalow", nil], @"location", - [NSArray arrayWithObjects:@"posh", @"dilapidated", @"substandard", nil], @"desc", - [NSArray arrayWithObjects:@"a litter of kittens", @"a trustworthy parrot", @"friends", nil], @"others", nil]; - NSLog([@"{name} lives in {location} with {others}" goatWithSubstitutions:substitions]); + NSDictionary *substitions = [NSDictionary dictionaryWithObjectsAndKeys: + [NSArray arrayWithObjects:@"fred", @"george", @"tom", nil], @"name", + [NSArray arrayWithObjects:@"a {desc} trailer", @"a slum", @"a {desc} bungalow", nil], @"location", + [NSArray arrayWithObjects:@"posh", @"dilapidated", @"substandard", nil], @"desc", + [NSArray arrayWithObjects:@"a litter of kittens", @"a trustworthy parrot", @"friends", nil], @"others", nil]; + NSLog([@"{name} lives in {location} with {others}" goatWithSubstitutions:substitions]); The generator will randomly select items from each substitution list used. So in the above case we can generate strings like: - george lives in a dilapidated bungalow with friends - fred lives in a dilapidated bungalow with a litter of kittens - tom lives in a posh bungalow with friends + george lives in a dilapidated bungalow with friends + fred lives in a dilapidated bungalow with a litter of kittens + tom lives in a posh bungalow with friends The substitution is recursive (as demonstrated by "location" above), so you can quite easily generate really long strings which somewhat make sense. @@ -31,58 +31,58 @@ Yes indeed. You can also call functions in the substitution list. Simply prefix your substitution in the list with "$", and instead of an NSArray point to an object & selector with an NSInvocation. e.g: - NSMutableDictionary *substitions2 = [NSMutableDictionary dictionaryWithObjectsAndKeys:nameList, @"name", - [NSArray arrayWithObjects:@"nice", @"disgusting", @"beautiful", @"horrible", nil], @"adj", - [NSArray arrayWithObjects:@"oceans", @"forests", @"ports", @"markets", nil], @"items", nil]; - - // Add a function - SEL sel_func = @selector(randomNumber:subs:); - NSMethodSignature * sig = [[self class] instanceMethodSignatureForSelector:sel_func]; - NSInvocation *func = [NSInvocation invocationWithMethodSignature:sig]; - [func setTarget:self]; - [func setSelector:sel_func]; - [substitions2 setValue:func forKey:@"$rnd"]; - - // And another - sel_func = @selector(capitalize:subs:); - sig = [[self class] instanceMethodSignatureForSelector:sel_func]; - func = [NSInvocation invocationWithMethodSignature:sig]; - [func setTarget:self]; - [func setSelector:sel_func]; - [substitions2 setValue:func forKey:@"$cap"]; - - // Print something! - NSLog([@"{$cap:{name}} is a {adj} planet with many {items}.

Simply send the message "goatNameWithRange:", supplying a minimum and maximum length of string to generate. e.g.: - NSString *goatName = @"ABOUSEITILETSTONLONUTHNO"; // character pairs - for (int i=0; i<100; i++) { - NSString *name = [goatName goatNameWithRange:NSMakeRange(4, 6)]; - NSLog(@"Goat name: %@", name); - } + NSString *goatName = @"ABOUSEITILETSTONLONUTHNO"; // character pairs + for (int i=0; i<100; i++) { + NSString *name = [goatName goatNameWithRange:NSMakeRange(4, 6)]; + NSLog(@"Goat name: %@", name); + } Which can generate names such as: - Goat name: LESE - Goat name: TSETUS - Goat name: USBOET + Goat name: LESE + Goat name: TSETUS + Goat name: USBOET Have fun!
