Never - Functional Programming Language

Never is a simple functional programming language. Technically it may be classified as syntactically scoped, strongly typed, call by value, functional programming language.

In practise Never offers basic data types, assignment, control flow, arrays, first order functions and some mathematical functions to make it useful to calculate expressions. Also it demonstrates how functions can be compiled, invoked and passed as parameters or results between other functions.

Getting Started

It is easy to download and compile Never language. Just clone repository and make the compiler in a few basic steps. To read more visit readthedocs.io site.

Prerequisites

Never requires basic Linux installation to be built. The following tools and libraries are needed:

gcc
glibc
bison / flex
libmath, libdl and libffi

Installing

Never can be installed in steps:

clone repository
cd never
mkdir build; cd build
cmake ..; make

asm.js wasm

To compile for asm.js or wasm targets use the following commands:

Get the latest sdk: git clone https://github.com/emscripten-core/emsdk.git

cd emsdk
./emsdk install latest
./emsdk activate latest
source ./emsdk_env.sh

Compile to native asm.js

mkdir build && cd build
emcmake cmake .. -DJS_ONLY=ON 
make

Compile to native wasm

mkdir build && cd build
emcmake cmake .. -DWASM_ONLY=ON 
make

Run

Now you should see never.js file in your build directory. You can overwrite ../never.js and open never.html, or modify never.html to load build/never.js file or load the file in JS console and run:

python -m SimpleHTTPServer 8000
# http://localhost:8000/never.html

var never = Module.cwrap('never','number',['string']);
never("func main() -> int { 123 }")
