scala-encase

An Scala library for changing between camelCase, snake_case, kebab-case, and more.

See also encase.js for the JavaScript version.

Installation

In SBT:

// Still need to set this up

Notes

This method will provides a global Encase object. That means that once you include it, you can use it like this:

var str = "camelCase";
var convertedStr = Encase.toLowerSnake(str);
// = "camel_case"

Encase supports switching to 6 cases:

• toLowerCamel (e.g. someVariableName)
• toUpperCamel (e.g. SomeVariableName)
• toLowerSnake (e.g. some_variable_name)
• toUpperSnake (e.g. SOME_VARIABLE_NAME)
• toLowerKebab (e.g. some-variable-name)
• toUpperKebab (e.g. SOME-VARIABLE-NAME)

Encase automatically detects the "from" case, so you only have to tell it what you want to switch to. It also provides a general separate function for splitting up strings:

val str = "camelCase";
val words = Encase.separate(str);
// = List("camel", "Case")

In addition to separate, Encase provides a convert function for making arbitrary conversions to any case:

The arguments are:

• headTransform: how the the first word should be transformed
• tailTransform: how the rest of the words should be transformed
• sep: how the words should be joined back together
• str: the string to operate on

Here's an example for converting any casing to "colon case" (which is used in products like Redis for key naming):

val str = "UpperCamel";
def lowerCase = (_: String).toLowerCase
val convertedStr = Encase.convert(lowerCase, lowerCase, ":", str);
// = "upper:camel"
