# go-ramda

Functional ramda (<https://ramdajs.com>) methods implement in Go

This package supports limited functions of ramda which are used ofter

## Functions

*The following functions are supported ramda func with some changes which is supported by go*

| function      | purpose                                                                               |

| DropLast      | returns removes sets of elements upto given value index from the last on given array  |
| Append        | appends given elements into give first array argument                                 |

*Following functions are type assertion functions which assert interface to go types*

| function      | purpose                                                                               |
| ------------- | ------------------------------------------------------------------------------------- |
| String        | assert to string type also converts string convertable values int, float64 and etc types into string     |
| Integer       | assert to int from interface  |
| Integer32     | assert to int32 from interface                             |
| Integer64     | assert to int64 from interface |
| Float64       | assert to float64 from interface |
| IntSlice      | assert to []int from interface |
| StringSlice   | assert to []string from interface |
| Typify        | returns given data if type of first arg and second arg other wise returns 2nd default value of 2nd argument type |

# Examples

*And(bool, bool...)*
This function will return bool value true or false
will return true If give all arguments are true.

```
  And(true, false, false) ==> false
  And(true, false, true) ==> false
  And(true, true, true, true, true) ==> true
```

*Or(bool, bool...)*
This function will return bool value true or false
Or will return true if give arguments atleast one argument is true.

```
  Or(true, false, false) ==> false
  Or(true, false, true) ==> false
  Or(true, true, true, true, true) ==> true
```

*Not(bool)*
This function will return bool value true or false
Not will return true if give argument is false.

```
user := User{
  Student: &UserStudent{
    Name: "Ambika",
    Address: Address{
      Street: "123 Car street",
    },
  },
  }
  Not(true) ==> false
  Not(false) ==> true
  Not(HasPath([]string{"Student", "Name"}, )) ==> false
```

*IfElse(bool, interface{}, interface{}) interface{}*
This function will return interface that can be any type based on 2nd and 3rd argument
If the given bool argument is true then will return 2nd argument otherwise will return 3rd argument.
arguments:
  - bool -> decider argument based on this return first or second argument
  - interface{} -> if section value this can be any type of value
  - interface{} -> if section value this can be any type of value

```
user := User{
  Student: &UserStudent{
    Name: "Ambika",
    Address: Address{
      Street: "123 Car street",
    },
  },
  }
  a := 5
  b := 6
  IfElse(a > b, a, b) ==> 6
  IfElse(IsEmpty(user.Student.Name), "Student-Name", user.Student.Name) ==> Ambika
  IfElse(HasPath([]string{"Student", "Name"}, user)) ==> false
```
_Note: response is interface so we need to do type assertion_

*Path([]string, interface{}) interface{}*
  This function will return any value on the given path in the 2rd argument data.
  If the given data is not have that path or traversable then will return nil.
arguments:
  - []string -> array of key string field name, path value to travers into the given object value, To indexing on slice next to the slice key field should be number string so we can index value on array.
  - interface{} -> object value to be search given path. can be Struct/Map/Slice that can be traversable

```
user := User{
  Student: &UserStudent{
    Name: "Ambika",
    Address: Address{
      Street: "123 Car street",
    },
  },
  Subjects: []Subject{
    {
      Name: "tamil",
      Total: 100,
      MarkSplit: MarkSplit{
        Theory: 80,
        Practical: 20,
      },
    },
    {
      Name: "chemistry",
      Total: 200,
      MarkSplit: MarkSplit{
        Theory: 60,
        Practical: 40,
      },
    },
  },
  }

Path([]string{"Student", "Name"}, user) ==> Ambika
  Path([]string{"Student", "FirstName"}, user) ==> nil
  String(Path([]string{"Student", "Subjects", "2", "Name"}, user)) ==> "chemistry"

a := "path"
  Path([]string{"A"}, a) ==> nil
```
_Note: response is interface so we need to do type assertion_

*PathOr(interface{}, []string, interface{}) interface{}*
This function will return any value on the given path in the 3rd argument data.
If the given data is not have that path or traversable then will return 1st argument value.
arguments:
  - interface{} -> default value argument this can be any type of value
  - []string -> array of key string field name, path value to travers into the given object value, To indexing on slice next to the slice key field should be number string so we can index value on array.
  - interface{} -> object value to be search given path. can be Struct/Map/Slice that can be traversable

```
// refer the user on example of Path function
PathOr("Student-Name", []string{"Student", "Name"}, user) ==> Ambika
PathOr("-", []string{"Student", "FirstName"}, user) ==> "-"
String(PathOr("unknown", []string{"Student", "Subjects", "2", "Name"}, user)) ==> "chemistry"
Int(PathOr(0, []string{"Student", "Subjects", "1", "MarkSplit", "Theory"}, user)) ==> 80

a := "path"
PathOr("", []string{"A"}, a) ==> ""

```
