.package(url: "https://github.com/mesqueeb/CaseAnything", from: "0.1.5")

14 case changing functions: camelCase, kebab-case, PascalCase and more...
A simple integration with nano package size. (SMALL footprint!)

I created this package because the other package that change cases do not cover all the 14 possibilities mine does.

import CaseAnything

CaseAnything has different behaviour if the string you pass has spaces or not.

• Without spaces it will split and format on every "part" it can detect
• With spaces it will split and format on every "word" based on those spaces

You can see that most functions by default remove special characters, and some functions keep special characters.

*You can control wether or not to keep or remove special characters like so:

// default:
camelCase("$catDog") == "catDog"
// force keeping special characters:
camelCase("$catDog", keepSpecialCharacters: true) == "$catDog"

// default:
pathCase("$catDog") == "$cat/Dog"
// force removing special characters:
pathCase("$catDog", keepSpecialCharacters: false) == "cat/Dog"

These cases do not change the casing of the words:

• dotNotation
• pathCase
• spaceCase

// default:
dotNotation("$catDog") == "cat.Dog"
// force lower case:
dotNotation("$catDog").toLowerCase() == "cat.dog"

As soon as there is a space in the target string, it will regard the input as a sentence and only split each part at the spaces.

Also note, that multiple sequential spaces are treated as one space.

Instead of removing all special characters, you can opt to keep some special characters.

In the example below we see:

• input: $cat-dog
• desired output: $CatDog

pascalCase("$cat-dog", keepSpecialCharacters: false)
// CatDog   → not what we want

pascalCase("$cat-dog", keepSpecialCharacters: true)
// $Cat-Dog → not what we want

pascalCase("$cat-dog", keep: ["$"])
// $CatDog  → desired output

I have extended regular alphabet with the most common Latin-1 Supplement special characters.

The coolest thing about this library is that it will "convert" special characters into regular alphabet for the cases used as variable names! 😎

// CONVERTS special characters:
camelCase("Çâfé Ågård")    == "cafeAgard"
pascalCase("Çâfé Ågård")   == "CafeAgard"
kebabCase("Çâfé Ågård")    == "cafe-agard"
snakeCase("Çâfé Ågård")    == "cafe_agard"
constantCase("Çâfé Ågård") == "CAFE_AGARD"
trainCase("Çâfé Ågård")    == "Cafe-Agard"
adaCase("Çâfé Ågård")      == "Cafe_Agard"
cobolCase("Çâfé Ågård")    == "CAFE-AGARD"
dotNotation("Çâfé Ågård")  == "Cafe.Agard"

// DOES NOT convert special characters:
spaceCase("Çâfé Ågård")    == "Çâfé Ågård"
pathCase("Çâfé Ågård")     == "Çâfé/Ågård"
lowerCase("Çâfé Ågård")    == "çâfé ågård"
upperCase("Çâfé Ågård")    == "ÇÂFÉ ÅGÅRD"
capitalCase("Çâfé Ågård")  == "Çâfé Ågård"

I have made sure there is great documentation available on hover!

With Better Touch Tool you can set up keyboard shortcuts to convert selected text with JavaScript. This repo provides an easy to install preset that has shortcuts for pascal, kebab and camel case! (thanks to @AndrewKoch) It even supports multi-cursors in VSCode!

Here is an example triggering keyboard shortcuts to convert the selected text to PascalCase; kebab-case; camelCase:

You can download the BTT preset from the source code: CaseAnything.bttpreset.

What keeps my package small, is that literally just uses a regex to separate "words".

// the source code is similar to:
public func splitOnSpecialChars(string: String) -> [String] {
  let splitRegex = try! NSRegularExpression(pattern: "^[a-z]+|[A-Z][a-z]+|[a-z]+|[0-9]+|[A-Z]+(?![a-z])")
  return splitRegex.matches(in: string, range: NSRange(string.startIndex..., in: string))
}

The actual regex used is a little bit more comprehensive and can be found here.
