Installation

moon update
moon add justjavac/case

Quick Start

// Core case conversions
@case.camel_case("hello world")       // "helloWorld"
@case.pascal_case("hello world")      // "HelloWorld"
@case.snake_case("hello world")       // "hello_world"
@case.kebab_case("hello world")       // "hello-world"
@case.constant_case("hello world")    // "HELLO_WORLD"

// Additional transformations
@case.swap_case("Hello World")        // "hELLO wORLD"
@case.title_case("the lord of rings") // "The Lord of Rings"
@case.reverse_case("hello")           // "olleh"

Real-world Use Cases

// API endpoint conversion
let apiEndpoint = "getUserProfile"
@case.kebab_case(apiEndpoint)        // "get-user-profile" (for URLs)
@case.snake_case(apiEndpoint)        // "get_user_profile" (for database)
@case.constant_case(apiEndpoint)     // "GET_USER_PROFILE" (for constants)

// Configuration keys
let configKey = "databaseConnectionString"
@case.constant_case(configKey)       // "DATABASE_CONNECTION_STRING"
@case.dot_case(configKey)            // "database.connection.string"
