## How to use

The usage of Enumer is the same as Stringer, so you can refer to the [Stringer docs](https://godoc.org/golang.org/x/tools/cmd/stringer)

# 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.
|
||||
|
||||
## 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
|
||||
|
||||
## 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"]
|
||||
"BöseÜberraschung" => ["Böse", "Überraschung"]
|
||||
"Two spaces" => ["Two", " ", "spaces"]
|
||||
"BadUTF8\xe2\xe2\xa1" => ["BadUTF8\xe2\xe2\xa1"]
