InflectorKit

InflectorKit is a port of the string inflection functionality from Rails ActiveSupport for Swift and Objective-C.

InflectorKit joins FormatterKit & TransformerKit in providing well-designed APIs for manipulating user-facing content.

Usage

Swift

import InflectorKit

for singular in ["person", "tomato", "matrix", "octopus", "fish"] {
    print("\(singular) → \(singular.pluralized)")
}
/*
Prints:
person → people
tomato → tomatoes
matrix → matrices
octopus → octopi
fish → fish
*/

// You can also add pluralization rules,
// including irregular and uncountable words:

let inflector = StringInflector.default
inflector.addPluralRule(#"^i(Pod|Pad)( Mini)?$"#, replacement: #"i$1s$2"#)
inflector.addIrregular(singular: "lol", plural: "lolz")
inflector.addUncountable("Herokai")

for singular in ["iPad Mini", "lol", "Herokai"] {
    print("\(singular) → \(singular.pluralized)")
}
/*
Prints:
iPad Mini → iPads Mini
lol → lolz
Herokai → Herokai
*/

Objective-C

#import "NSString+InflectorKit.h"

for (NSString *singular in @[@"person", @"tomato", @"matrix", @"octopus", @"fish"]) {
  NSLog(@"%@ → %@", singular, [singular pluralizedString]);
}

/*
Prints:
person → people
tomato → tomatoes
matrix → matrices
octopus → octopi
fish → fish
*/

// You can also add pluralization rules,
// including irregular and uncountable words:

TTTStringInflector *inflector = [TTTStringInflector defaultInflector];
[inflector addPluralRule:@"^i(Pod|Pad)( Mini)?$" withReplacement:@"i$1s$2"];
[inflector addIrregularWithSingular:@"lol" plural:@"lolz"];
[inflector addUncountable:@"Herokai"];

for (NSString *singular in @[@"iPad Mini", @"lol", @"Herokai"]) {
  NSLog(@"%@ → %@", singular, [singular pluralizedString]);
}

/*
Prints:
iPad Mini → iPads Mini
lol → lolz
Herokai → Herokai
*/
