Inflections

Inflections is a port of several of the ActiveSupport Inflector methods into Objective C. This was inspired by the wonderful inflection.js by Ryan Schuft (http://code.google.com/p/inflection-js/). The framework has all the support for camelization pluralization and some of the other nice features. It also depends on RegexKitLite for Regex support.

Usage

The simplest way to use the project is to add the NSString+Inflections.h and NSString+Inflections.m to your project. You will also need to have RegexKitLite in your project.

To install RegexKitLite check their site: http://regexkit.sourceforge.net/RegexKitLite/#AddingRegexKitLitetoyourProject

Supported Methods

- (NSString *)pluralize;

Returns the plural form of the word in the string.

- (NSString *)singularize;

The reverse of +pluralize+, returns the singular form of a word in a string.

- (NSString *)humanize;

Capitalizes the first word and turns underscores into spaces and strips a trailing "_id", if any. Like +titleize+, this is meant for creating pretty output.

- (NSString *)titleize;

Capitalizes all words that are not part of the nonTitlecasedWords.

- (NSString *)tableize;

Create the name of a table like Rails does for models to table names. This method uses the +pluralize+ method on the last word in the string.

- (NSString *)classify;

Create a class name from a plural table name like Rails does for table names to models.

- (NSString *)camelize;

Converts an underscored separated string into a CamelCasedString.

- (NSString *)camelizeWithLowerFirstLetter;

Converts an underscored separated string into a camelCasedString with the first letter lower case.

- (NSString *)underscore;

Makes an underscored, lowercase form from the expression in the string.

- (NSString *)dasherize;

Replaces underscores with dashes in the string.

- (NSString *)demodulize;

Removes the module part from the expression in the string.

- (NSString *)foreignKey;

Creates a foreign key name from a class name.

- (NSString *)foreignKeyWithoutIdUnderscore;

Creates a foreign key name from a class name without the underscore separating the id part.

- (NSString *)ordinalize;

Turns a number into an ordinal string used to denote the position in an ordered sequence such as 1st, 2nd, 3rd, 4th.

- (NSString *)capitalize;

Capitalizes the first letter and makes everything else lower case.

Issues

Currently some of the singularization tests are passing. The testing suite was ported over from Rails 3.0 and most of it's working. There are still a couple odd cases though.
