# Felix
An advanced, statically typed, high performance scripting language with native C++ embedding.
## Features
### Autobuilder
This file:
```
// hello.flx
println$ "Hello World";
```
can be run directly:
```bash
flx hello.flx
```
It __just works__. No makefiles. No compiler switches.
Automatic caching and dependency checking for Felix and C++.
Uses a *flx_pkgconfig* database consisting of a directory
of `*.fpc` files to specify and find libraries and header
files based on in language abstract keys.
### Hyperlight Performance
The aim is to run faster than C.
Underneath Felix generates highly optimised machine
binaries which outperform most interpreters, bytecode compilers,
virtual machines, and sometimes compiled languages including C and C++.
Felix is an aggressive inliner which performs whole program
analysis and high level optimisations such as parallel assignment,
self-tail call elimination.
Felix generates optimised C++ which is then compiled and optimised
again by your system C++ compiler.
Compiler | Ack | Takfp
-------------|--------|-----------
Felix/clang | 3.71 | 6.23
Clang/C++ | 3.95 | 6.29
Felix/gcc | 2.34 | 6.60
Gcc/C++ | 2.25 | 6.25
Ocaml | 2.93 | 8.41
### C and C++ embedding
Felix is a C++ code generator specifically designed so that
all your favourite C and C++ libraries can be embedded
with little or no glue logic:
```
// required header
header vector_h = '#include ';
// C++11 for smart pointers
header memory_h = '#include '
requires package "cplusplus_11"
;
// types
type vector[T] = "::std::shared_ptr<::std::vector1>>"
requires vector_h, memory_h
;
type viterator[T] = "::std::vector1>::iterator"
requires vector_h
;
// constructor
ctor[T] vector[T] : unit = "::std::make_shared<::std::vector1>>()";
// operations
proc push_back[T] : vector[T] * T = "$1->push_back($2);";
proc push_back[T] (v: vector[T]) (elt:T) => push_back(v,elt);
fun stl_begin[T] : vector[T] -> viterator[T] = "$1->begin()";
fun deref[T] : viterator[T] -> T = "*$1";
// example use
var v = vector[int]();
v.push_back 42;
println$ *v.stl_begin;
```
## Getting Started
### Prerequisites
* Python 3
* Ocaml 4.06.1 (only for source build)
* C++ compiler: g++, clang++, or msvc
### Extras (can be installed later)
* SDL2 for graphics
* GNU GMP, GNU GSL
### Build from Source
#### Linux
```
git clone https://github.com/felix-lang/felix.git
cd felix
. buildscript/linuxsetup.sh
make
sudo make install # optional!
```
#### OSX
```
git clone https://github.com/felix-lang/felix.git
cd felix
. buildscript/macosxsetup.sh
make
sudo make install # optional!
```
#### Building with Nix
On platforms supporting Nix, you can set up a build and runtime environment
by running:
```
git clone https://github.com/felix-lang/felix.git
cd felix
nix-shell shell.nix
. buildscript/linuxsetup.sh
make
```
This will do an in place "install" of the Felix binaries. Note that
this should work on OS X with Nix, but needs to be tested.
#### Windows
Follow the instructions on [the Wiki](https://github.com/felix-lang/felix/wiki/Building-Felix-From-Source#windows-10-with-visual-studio-2022).
## Packages
#### Arch Linux
Use provided [PKGBUILD](./src/misc/PKGBUILD) to make an installable package.
It is also available in the [AUR repository](https://aur.archlinux.org/packages/felix/)
```
cd src/misc
makepkg
sudo pacman -U felix-VERSION.pkg.tar.xz
```
