# CamelCase [![GoDoc](http://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](http://godoc.org/github.com/fatih/camelcase) [![Build Status](http://img.shields.io/travis/fatih/camelcase.svg?style=flat-square)](https://travis-ci.org/fatih/camelcase)
CamelCase is a Golang (Go) package to split the words of a camelcase type
string into a slice of words. It can be used to convert a camelcase word (lower
or upper case) into any type of word.
## Install
```bash
go get github.com/fatih/camelcase
```
## Usage and examples
```go
splitted := camelcase.Split("GolangPackage")
fmt.Println(splitted[0], splitted[1]) // prints: "Golang", "Package"
```
Both lower camel case and upper camel case are supported. For more info please
check: [http://en.wikipedia.org/wiki/CamelCase](http://en.wikipedia.org/wiki/CamelCase)
Below are some example cases:
```
lowercase => ["lowercase"]
Class => ["Class"]
MyClass => ["My", "Class"]
MyC => ["My", "C"]
HTML => ["HTML"]
PDFLoader => ["PDF", "Loader"]
AString => ["A", "String"]
SimpleXMLParser => ["Simple", "XML", "Parser"]
vimRPCPlugin => ["vim", "RPC", "Plugin"]
GL11Version => ["GL", "11", "Version"]
99Bottles => ["99", "Bottles"]
May5 => ["May", "5"]
BFG9000 => ["BFG", "9000"]
```
