# Golang Stringy
|
||||
A Golang string manipulation utility which have many useful functionality like camelcase, snakecase, kebabcase or slugify, custom delimiter, between, and able to uppercase or lowercase them as needed. You can convert camelcase to snakecase or kebabcase, or snakecase to camelcase and kebabcase and vice versa. This package was inspired from PHP [danielstjules/Stringy](https://github.com/danielstjules/Stringy).

## Why?
|
||||
|
||||
Golang has very rich strings core package but some extra helper function and not available and this stringy package is here to fill that void. Plus there are other some packages in golang, that have same functionality but for some extreme cases they fail to provide correct output. This package cross flexibility is it's main advantage. You can convert to camelcase to snakecase or kebabcase or vice versa.
|
||||
|
||||
```go
|
||||
str := New("hello__man how-Are you??")
|
||||
result := str.CamelCase("?","")
|
||||
fmt.Println(result) // HelloManHowAreYou
|
||||
|
||||
snakeStr := str.SnakeCase("?","")
|
||||
fmt.Println(snakeStr.ToLower()) // hello_man_how_are_you
|
||||
|
||||
kebabStr := str.KebabCase("?","")
|
||||
fmt.Println(kebabStr.ToUpper()) // HELLO-MAN-HOW-ARE-YOU
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
``` bash
|
||||
$ go get -u -v github.com/gobeam/Stringy
|
||||
```
|
||||
|
||||
or with dep
|
||||
|
||||
``` bash
|
||||
$ dep ensure -add github.com/gobeam/Stringy
|
||||
```
|
||||
|
||||
|
||||
## Functions
|
||||
|
||||
##### Between(start, end string) StringManipulation
|
||||
|
||||
Between takes two string params start and end which and returns value which is in middle of start and end part of input. You can chain to upper which with make result all uppercase or ToLower which will make result all lower case or Get which will return result as it is.
|
||||
|
||||
```go
|
||||
strBetween := New("HelloMyName")
|
||||
fmt.Println(strBetween.Between("hello", "name").ToUpper()) // MY
|
||||
```
|
||||
|
||||
##### Boolean() bool
|
||||
|
||||
Boolean func returns boolean value of string value like on, off, 0, 1, yes, no returns boolean value of string input. You can chain this function on other function which returns implemented StringManipulation interface.
|
||||
|
||||
```go
|
||||
boolString := New("off")
|
||||
fmt.Println(boolString.Boolean()) // false
|
||||
```
|
||||
|
||||
##### CamelCase(rule ...string) string
|
||||
|
||||
CamelCase is variadic function which takes one Param rule i.e slice of strings and it returns input type string in camel case form and rule helps to omit character you want to omit from string. By default special characters like "_", "-","."," " are treated like word separator and treated accordingly by default and you dont have to worry about it.
|
||||
|
||||
```go
|
||||
camelCase := New("ThisIsOne___messed up string. Can we Really camel-case It ?##")
|
||||
fmt.Println(camelCase.CamelCase("?", "", "#", "")) // ThisIsOneMessedUpStringCanWeReallyCamelCaseIt
|
||||
```
|
||||
look how it omitted ?## from string. If you dont want to omit anything and since it returns plain strings and you cant actually cap all or lower case all camelcase string its not required.
|
||||
|
||||
```go
|
||||
camelCase := New("ThisIsOne___messed up string. Can we Really camel-case It ?##")
|
||||
fmt.Println(camelCase.CamelCase()) // ThisIsOneMessedUpStringCanWeReallyCamelCaseIt?##
|
||||
```
|
||||
|
||||
##### ContainsAll(check ...string) bool
|
||||
|
||||
ContainsAll is variadic function which takes slice of strings as param and checks if they are present in input and returns boolean value accordingly.
|
||||
|
||||
```go
|
||||
contains := New("hello mam how are you??")
|
||||
fmt.Println(contains.ContainsAll("mam", "?")) // true
|
||||
```
|
||||
|
||||
##### Delimited(delimiter string, rule ...string) StringManipulation
|
||||
|
||||
Delimited is variadic function that takes two params delimiter and slice of strings named rule. It joins the string by passed delimeter. Rule param helps to omit character you want to omit from string. By default special characters like "_", "-","."," " are treated like word separator and treated accordingly by default and you dont have to worry about it. If you don't want to omit any character pass empty string.
|
||||
|
||||
```go
|
||||
delimiterString := New("ThisIsOne___messed up string. Can we Really delimeter-case It?")
|
||||
fmt.Println(delimiterString.Delimited("?").Get())
|
||||
```
|
||||
You can chain to upper which with make result all uppercase or ToLower which will make result all lower case or Get which will return result as it is.
|
||||
|
||||
|
||||
##### Get() string
|
||||
|
||||
Get simply returns result and can be chained on function which returns StringManipulation interface view above examples
|
||||
|
||||
|
||||
##### KebabCase(rule ...string) StringManipulation
|
||||
|
||||
KebabCase/slugify is variadic function that takes one Param slice of strings named rule and it returns passed string in kebab case or slugify form. Rule param helps to omit character you want to omit from string. By default special characters like "_", "-","."," " are treated like word separator and treated accordingly by default and you don't have to worry about it. If you don't want to omit any character pass nothing.
|
||||
|
||||
```go
|
||||
str := New("hello__man how-Are you??")
|
||||
kebabStr := str.KebabCase("?","")
|
||||
fmt.Println(kebabStr.ToUpper()) // HELLO-MAN-HOW-ARE-YOU
|
||||
fmt.Println(kebabStr.Get()) // hello-man-how-Are-you
|
||||
```
|
||||
You can chain to upper which with make result all uppercase or ToLower which will make result all lower case or Get which will return result as it is.
|
||||
|
||||
|
||||

|
||||
|
||||
```go
|
||||
lines := New("fòô\r\nbàř\nyolo123")
