# ToyLang
[](https://github.com/maxbarsukov/toylang/actions/workflows/main.yml)
[](https://codecov.io/gh/maxbarsukov/toylang)
***ToyLang*** is interpreted high-level fully OOP language with *Python-like* syntax and dynamic typing.
> Complex is better than complicated.
As a multi-paradigm language, ***ToyLang*** supports object-oriented and imperative programming styles both.
- As in Python, blocks of code are delimited **by** their **indentation**.
- Classes are declared with the `class` keyword.
- Methods can be defined anywhere using the `def` keyword.
- If a method takes no arguments, *parenthesis can be skipped*, like in
**Ruby**.
- The *last value evaluated in a method is its return value*.
- ***Everything is an object***.
## Installation
$ gem install toylang
## Usage
Run REPL:
```bash
toylang
```
or run file:
```bash
toylang your_code.tlg
```
## Examples of code
```python
# comment
println("Hello World")
"Hello World".println # Hello World
println(2 + 2 ** 5) # 34
def hello(name):
"Hi, " + name + "!"
hello("Max").println # => Hi, Max!
a = 23
b = a + 2
println(b) # => 25
Hey = 5 # constant
if (2 > 1):
println("Yeah!")
else:
println("Something goes bad!")
if (false):
print("Won't be printed")
```
Cycles:
```python
a = 0
while (a != 3):
println(a)
a = a + 1
# => 0 1 2
```
OOP:
```python
# class defination
class Klass:
def my_method:
true
# object creating
k = Klass.new
k.my_method.print # => true
# monkey patching
class Number:
def ten:
10
1.ten.println # => 10
class Number:
def ten:
11
1.ten.println # => 11
# inheritance
class Animal:
def is_a_human:
false
def say:
"..."
class Dog < Animal:
def say:
"Bark!"
dog = Dog.new
animal = Animal.new
println(animal.say) # ...
println(dog.say) # Bark!
println(dog.is_a_human) # false
```
