# Nex Lang
> [!NOTE]
> This project is currently in WIP.
Nex Lang is an experimental (toy) programming language written in C++, that was made as a learning project. The purpose of this language is not to be the fastest or the most functional but to serve as an example of how a programming language is created.
I undertook this project as I was interested in how compilers work, and so far the experience has been rewarding and interesting. Although it was very tempting, I have decided to not continue using LLVM for code generation as I wanted to use this project to get better at reading and writing assembly code. I am trying to build this project entirely from scratch, therefore, most things will be found out through trial and error, so don't expect the implementation to be perfect.
# Example
This simple application showcases some features of Nex Lang.
```nex-lang
# main.nex
#$ multiline
comment $#
# main function
fn main() {
# initialising variables
var foo = 200;
var bar = 600;
# initialise a variable using maths expression
var x = 8 * 1 / 5 + 2;
# infinite loop
set label;
go label;
# exit with variable foo (exit code 200)
esc foo;
}
#$ another
multiline
comment $#
# another function
fn test() {
# return a maths expression
ret 5 + 10 * 2;
}
```
# Info
### Commands
Below, you can see the usage of the nex executable and some options.
```
Nex: Usage: nex -o
--version Displays all version information
-o Specifies the file to dump asm code into
```
### Assembly
Currently, Nex only outputs Intel x64 assembly. You can execute the assembly spat out by Nex using nasm.
*Install commands for Arch Linux:*
```bash
sudo pacman -S nasm
```
To execute the assembly:
```bash
nasm -felf64 out.asm
ld -o out out.o
```
### Extention
`.nex` for obvious reasons.
# Building
#### Linux:
Building Nex on Linux requires you to have CMake, Make, and GCC.
*Install commands for Arch Linux:*
```bash
sudo pacman -S cmake base-devel
```
To build Nex:
```bash
git clone https://github.com/dafiliks/nex-lang
mkdir nex-lang/build
cd nex-lang/build
cmake ..
make
# You can execute Nex with the commands below
cd compiler/src
./nex
```
# Contributing
All contributions are welcome, so feel free to submit issues/pull requests. Coding style doesn't matter as long as naming is clear. Programming is art.
