# Text and Input Validation in Golang

I've created this helping script for my APIs to deal with user inputs. Just clone the repo and use it in your project.

## Usage:

1. Define the validator

  `

  userInput := validator("blah!blah!blah!")

  `

2. Apply the methods

   `userInput.Required().oneLowerCase().check()`     `// will return true or false` 

## Methods

use `.check()` after all methods to return the `boolean` value, otherwise the method will return `type struct`

| Methods            | Descrption                                                   |

| ------------------ | :----------------------------------------------------------- |

| Required()         | returns `false` if input is empty                            |

| minLength(int)     | returns `false` if input is less than provided minimum value |

| maxLength(int)     | returns `false` if input is greater than provided maximum value |

| isEmail            | return `false` if input is not an email address              |

| oneLowerCase       | return `false` if input value doesn't have at least one lowercase character |

| allLowerCase       | return `false`if input value doesn't have all lowercase characters |

| oneUpperCase       | return `false` if input value doesn't have at least one uppercase character |

| allUpperCase       | return `false` if input value doesn't have all uppercase characters |

| oneNumber          | return `false` if input value doesn't have at least one number character |

| isSpecialCharacter | return `false` if input value doesn't have at least one special character |

## Using Multiple Methods:

I've design the methods in a way that multiple methods can be used in a line.

For example to check for a strong password you can use.

`userInput.minLength(8).oneLowerCase().oneUpperCase().oneNumber().isSpecialCharacter().check()`

The above code will check for the applied methods and will return boolean `false` if any method doesn't validate the password.
