Typ

GoDoc Build Status Coverage Status Go Report Card Mentioned in Awesome Go

Typ is a library providing a powerful interface to impressive user experience with conversion and fetching data from built-in types in Golang

Features

  • Safe conversion along built-in types like as bool, int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64, float32, float64, complex64, complex128, string
  • Null types for all primitive types with supported interfaces: json.Unmarshaler, json.Marshaler, sql.Scanner, driver.Valuer
  • Value retriever for multidimensional unstructured data from interface
  • Conversion functions present via interface (reflection) and native types for better performance
  • Some humanize string conversion functions

Installation

Use go get to install the latest version of the library.

    go get -u github.com/gurukami/typ

Then include package in your application and enjoy.

    import "github.com/gurukami/typ/v2"

Usage

Of(interface{}) conversion from interface value to built-in type

// typ.Of(v interface{}, options ...Option).{Type}(defaultValue ...{Type})
//
// Where {Type} any of 
//      Bool, 
//      Int, Int8, Int16, Int32, Int64, 
//      Uint, Uint8, Uint16, Uint32, Uint64, 
//      Float32, Float, 
//      Complex64, Complex, 
//      String
//
// All methods for conversion returns {Type}Accessor with helpful methods
//
//      V() - value of type
//      Present() - determines whether a value has been set
//      Valid() - determines whether a value has been valid (without error)
//      Err() error - returns underlying error  
//      Set(value {Type}) - saves value into current struct  
//      Clone() {Type}Accessor - returns new instance of current struct with preserved value & error  
//      
//      Scan(value interface{})         | sql.Scanner
//      Value() (driver.Value, error)   | driver.Valuer
//
//      UnmarshalJSON(b []byte) error   | json.Unmarshaler
//      MarshalJSON() ([]byte, error)   | json.Marshaler

// Valid
nv := typ.Of(3.1415926535, typ.FmtByte('g'), typ.Precision(4)).String()
fmt.Printf("Value: %v, Valid: %v, Present: %v, Error: %v\n", nv.V(), nv.Valid(), nv.Present(), nv.Error)
// Output: Value: 3.142, Valid: true, Present: true, Error: <nil>

// Not valid
nv = typ.Of(3.1415926535).Int()
fmt.Printf("Value: %v, Valid: %v, Present: %v, Error: %v\n", nv.V(), nv.Valid(), nv.Present(), nv.Error)
// Output: Value: 3, Valid: false, Present: true, Error: value can't safely convert

Native conversion without reflection when type is know

// For the best performance always use this way if you know about exact type
//
// typ.{FromType}{ToType}(value , [options ...{FromType}{ToType}Option]).V()
// 
// Where {FromType}, {ToType} any of 
//      Bool, 
//      Int, Int8, Int16, Int32, Int64, 
//      Uint, Uint8, Uint16, Uint32, Uint64, 
//      Float32, Float, 
//      Complex64, Complex, 
//      String
//
// All methods for conversion returns {Type}Accessor interface with helpful methods & fields, additional info you can read in example above

// Valid
nv := typ.FloatString(3.1415926535, typ.FloatStringFmtByte('g'), typ.FloatStringPrecision(4))
fmt.Printf("Value: %v, Valid: %v, Present: %v, Error: %v\n", nv.V(), nv.Valid(), nv.Present(), nv.Error)
// Output: Value: 3.142, Valid: true, Present: true, Error: <nil>

// Not valid
nv = typ.FloatInt(3.1415926535)
fmt.Printf("Value: %v, Valid: %v, Present: %v, Error: %v\n", nv.V(), nv.Valid(), nv.Present(), nv.Error)
// Output: Value: 3, Valid: false, Present: true, Error: value can't safely convert

Retrieve multidimensional unstructured data from interface

data := map[int]interface{}{
   0: []interface{}{
      0: map[string]int{
         "0": 42,
      },
   },
}

// Instead of do something like this 
//  data[0].([]interface{})[0].(map[string]int)["0”]
//      and not caught a panic
// use this

// Value exists
nv := typ.Of(data).Get(0, 0, "0").Interface()
fmt.Printf("Value: %v, Valid: %v, Present: %v, Error: %v\n", nv.V(), nv.Valid(), nv.Present(), nv.Error)
// Output: Value: 42, Valid: true, Present: true, Error: <nil>

// Value not exists
nv = typ.Of(data).Get(3, 7, "5").Interface()
fmt.Printf("Value: %v, Valid: %v, Present: %v, Error: %v\n", nv.V(), nv.Valid(), nv.Present(), nv.Error)
// Output: Value: <nil>, Valid: false, Present: false, Error: out of bounds on given data
