# CamelCase [](http://godoc.org/github.com/fatih/camelcase) [](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.
|
||
|
|
|
||
|
|
## Splitting rules:
|
||
|
|
|
||
|
|
1. If string is not valid UTF-8, return it without splitting as
|
||
|
|
single item array.
|
||
|
|
2. Assign all unicode characters into one of 4 sets: lower case
|
||
|
|
letters, upper case letters, numbers, and all other characters.
|
||
|
|
3. Iterate through characters of string, introducing splits
|
||
|
|
between adjacent characters that belong to different sets.
|
||
|
|
4. Iterate through array of split strings, and if a given string
|
||
|
|
is upper case:
|
||
|
|
* if subsequent string is lower case:
|
||
|
|
* move last character of upper case string to beginning of
|
||
|
|
lower case string
|
||
|
|
|
||
|
|

## Usage and examples
|
||
|
|
|
||
|
|
```go
|
||
|
|
splitted := camelcase.Split("GolangPackage")
|
||
|
|
|
||
|
|
fmt.Println(splitted[0], splitted[1]) // prints: "Golang", "Package"
|
||
|
|
```
|
||
|
|
|
