# FlowLang
[](https://github.com/luizgabriel/FlowLang/actions/workflows/rust.yml)
[WIP] A ~statically typed~, functional programming language.
## Example Syntax:
### Function Definition & Application
```hs
square x = x * x
hypotenuse x y = sqrt (square x + square y)
hypotenuse 3 4
```
### Operator Functions Definitions & Application
```hs
(**) x y = hypotenuse x y
3 + (5 ** 6) / 2
```
### Piping & Composing Operators
```hs
add5 = (+) 5
times2 = (*) 2
7 |> times2 |> add5
add5_and_times2 = add5 >> times2
add5_and_times2 10
```
### If Expressions
```hs
max x y = if x > y then x else y
min x y = if x < y then x else y
max 5 -7
min 6.8 2.7
```
### Lambda Expressions
```hs
add1 = x -> x + 1
add1 5
```
### Import Modules
Loads module from `./examples/math.fw`
```hs
import examples::math
eq_root1 1.0 3.0 2.0
```
### Recursive Functions
```hs
fib n = if n < 1 then 1 else fib (n - 1) + fib (n - 2)
```
### Block Expressions
The last statement is the return value.
```hs
x = {
a = 1;
b = 2;
a + b
}
some_function x y = {
a = x * x;
b = y * y;
a + b
}
```
## Getting Started
Install the **Rust** programming language:
> [https://www.rust-lang.org/pt-BR/learn/get-started](https://www.rust-lang.org/pt-BR/learn/get-started)
Clone this repository:
```
git clone git@github.com:luizgabriel/FlowLang.git
cd FlowLang
```
Run the REPL (Read Evaluate Parse Loop) with:
```sh
cargo run -p repl -q
```
