Rail

A straightforward programming language.

Rail is an experimental concatenative programming language. It is under wild development and zero stability between versions is guaranteed.

$ rail i
rail 0.17.0
> 1 1 + print
2
> [ 1 + ] "inc" def
> [ dup print ] "p" def
> 1 [ p inc ] 2 times print
1
2
3
> [ [ false ] [ "bye" ] [ true ] [ "hi" ] ] opt print
"hi"

Installation

For now...

$ cargo install rail-lang

Usage

Currently you'll need to check out at least the rail-src directory of this repository, and execute rail in the same directory. (Or run with rail --no-stdlib ETC)
