# Lantern
**Lantern** is a [stack based](https://en.wikipedia.org/wiki/Stack-oriented_programming), [interpreted](https://en.wikipedia.org/wiki/Interpreter_(computing)) programming language written in **C**.
The goal of the project is creating a fast, bloatless and powerful programming tool
that can be used for multiple purposes.
The language has **access to the underlying memory structure** and in general
is desinged to be easily used as a [low level programming language](https://en.wikipedia.org/wiki/Low-level_programming_language) too.
Lantern is, due to the stackbased paradigm of the language it is written in
[reverse polish notation](https://en.wikipedia.org/wiki/Reverse_Polish_notation).
wich sets it apart from a lot languages that work with AST or other structures.
## Feature list

## Building
### Linux
#### Requirements
- GCC Compiler
- Make command
```console
mkdir bin
make
```
### Windows
#### Requirements
- GCC Compiler
```console
mkdir bin
build.bat
```
## Example Usage
### A implentation of the [FizzBuzz problem](https://de.wikipedia.org/wiki/Fizz_buzz)
```bash
0 = counter
while counter 10000 < run
counter 3 % 0 == counter 5 % 0 == and if
"fizzbuzz" println
elif counter 3 % 0 == then
"fizz" println
elif counter 5 % 0 == then
"buzz" println
end
counter println
counter 1 + = counter
end
```
## Inspiration
- [Forth](https://de.wikipedia.org/wiki/Forth_(Programmiersprache)), a stack based, imperative programming language
- [Python](https://de.wikipedia.org/wiki/Python_(Programmiersprache)), a easy to used, interpreted programming language
- [C](https://de.wikipedia.org/wiki/C_(Programmiersprache)), a statically typed, low level programming language
