# OwnLang
|
||||
|
||||
OwnLang - dynamic functional programming language. Available for PC, Android and Java ME devices.
|
||||
OwnLang - dynamic functional programming language inspired by Scala and Python. Available for PC, Android and Java ME devices.
|
||||
|
||||
## Key features
|
||||
|
||||
#### Function values
|
||||
|
||||
Functions are values, so we can store them to variables for operating.
|
||||
|
||||
```scala
|
||||
operations = {
|
||||
"+" : def(a,b) = a+b,
|
||||
"-" : def(a,b) = a-b,
|
||||
"*" : def(a,b) = a*b,
|
||||
"/" : ::division
|
||||
}
|
||||
def division(v1, v2) {
|
||||
if (v2 == 0) return "error"
|
||||
return v1 / v2
|
||||
}
|
||||
|
||||
for operation : operations {
|
||||
println operation(2, 3)
|
||||
}
|
||||
```
|
||||
|
||||
#### Pattern Matching
|
||||
|
||||
Pattern matching with value pattern, tuple pattern, list pattern and optional condition.
|
||||
|
||||
```scala
|
||||
def factorial(n) = match n {
|
||||
case 0: 1
|
||||
case n if n < 0: 0
|
||||
case _: n * factorial(n - 1)
|
||||
}
|
||||
|
||||
def fizzbuzz(limit = 100) {
|
||||
for i = 1, i <= limit, i++ {
|
||||
println match [i % 3 == 0, i % 5 == 0] {
|
||||
case (true, false): "Fizz"
|
||||
case (false, true): "Buzz"
|
||||
case (true, true): "FizzBuzz"
|
||||
case _: i
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Functional data operations
|
||||
|
||||
Operate data in functional style.
|
||||
|
||||
```scala
|
||||
use "std"
|
||||
use "functional"
|
||||
|
||||
nums = [1,2,3,4,5,6,7,8,9,10]
|
||||
nums = filter(nums, def(x) = x % 2 == 0)
|
||||
// Squares of even numbers
|
||||
squares = map(nums, def(x) = x * x)
|
||||
foreach(squares, ::echo)
|
||||
// Sum of squares
|
||||
sum = reduce(squares, 0, def(x, y) = x + y)
|
||||
println "Sum: " + sum
|
||||
```
|
||||
|
||||
#### Operator overloading
|
||||
|
||||
Why not?
|
||||
|
||||
```scala
|
||||
use "std"
|
||||
use "types"
|
||||
use "math"
|
||||
|
||||
def `..`(a, b) = range(a, b - 1)
|
||||
def `**`(a, b) = int(pow(a, b))
|
||||
for y : 1 .. 10 {
|
||||
println sprintf("2 ^ %d = %d", y, 2 ** y)
|
||||
}
|
||||
```
|
||||
|
||||
#### Network module
|
||||
|
||||
Easy async HTTP requests with `http` module.
|
||||
|
||||
```scala
|
||||
use "std"
|
||||
use "http"
|
||||
use "functional"
|
||||
|
||||
// GET request
|
||||
http("https://api.github.com/events", def(r) {
|
||||
use "json"
|
||||
events = jsondecode(r)
|
||||
})
|
||||
|
||||
// POST request
|
||||
http("http://jsonplaceholder.typicode.com/users", "POST", {
|
||||
"name": "OwnLang",
|
||||
"versionCode": 10
|
||||
}, ::echo)
|
||||
|
||||
// PATCH request
|
||||
http("http://jsonplaceholder.typicode.com/users/2", "PATCH", {"name": "Patched Name"}, ::patch_callback)
|
||||
|
||||
def patch_callback(v) {
|
||||
println v
|
||||
}
|
||||
```
