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 0.12.0
> 1 1 + .s
2
> [ 1 + ] "inc" def
> 1 .s [ inc .s ] 3 times drop
1
2
3
4
> [ [ false ] [ "goodbye" ] [ true ] [ "hello" ] ] opt .s
"hello"

Installation

$ cargo install rail-lang

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)
