Crowlang
========
This project is me experimenting with creating my own programming language.
For this project I am using C++23.
Crow's syntax is somewhat inspired by Swift and Rust.
In this programming language expressions are not statements.
This allows us to write code without any need for semicolons.
One of the main focuses of the language is enforcing safe constructs by not allowing certain expressions as statements.
Here a hello world.
```go
fn main() -> int {
defer {
println("Defer!")
}
println("Hello World!")
}
```
## Dependencies
In order to compile the project you will need to following dependencies:
- C++ compiler with support for C++23.
- [Invoke](https://www.pyinvoke.org/) (Used to invoke CMake and scripts)
- [Cmake](https://cmake.org/) (Main buildsysstem)
- [CLI11](https://github.com/CLIUtils/CLI11) (CLI option parsing library)
- [rang](https://github.com/agauniyal/rang/tree/master) (cross platform terminal coloring library)
- [tabulate](https://github.com/p-ranav/tabulate) (Text table library)
- [Boost](https://www.boost.org/) (Utility libraries for C++)
- [LLVM](https://llvm.org) (LLVM is used for code generation and optimization)
- [libclang](https://clang.llvm.org/doxygen/group__CINDEX.html) (libclang for compiling C++ sources (part of the LLVM project.))
- [cereal](https://uscilab.github.io/cereal/) (Serialization library used for the AST)
- [libassert](https://github.com/jeremy-rifkin/libassert) (Modern assertion library for compile and runtime assertion checking)
- [pybind11]() (Used to generate C++ to Python bindings.)
### Buildsystem
In order to compile the project you will need a couple of dependencies.
First we use invoke to invoke different python scripts, to orchestrate building the project.
In order to install invoke it is best to use pipx.
Which is installed using:
```shell
apt install -y pipx
```
In order to make use of invoke you should install it through `pipx`.
```shell
pipx install invoke
```
The you can invoke the appropriate setup script for your OS by running:
```shell
inv setup
```
If your OS is not supported it is best to checkout `tools/setup` and figure out what dependencies you require.
### Build
After installing the necessary dependencies you can build the compiler by running:
```
inv build --parallel
```
