If you already know [Forth](http://www.forth.org/), [Factor](http://factorcode.org/) or [Joy](http://www.kevinalbrecht.com/code/joy-mirror/), or if you ever used an [RPN](https://en.wikipedia.org/wiki/Reverse_Polish_notation) calculator, then min will look somewhat familiar to you. If not, well, here's how a short min program looks like: ; This is a comment (1 2 3 4 5) (dup *) map This program returns a list containing the square values of the first five integer numbers: (1 4 9 16 25) Let's see how it works: 1. First a list containing the first five integer is pushed on the stack. 2. Then, another list containing two symbols (`dup` and `*`) is pushed on the stack. This constitutes a quoted program which, when executed duplicates (`dup`) the first element on the stack and then multiplies (`*`) the two elements together. 3. Finally, the symbol `map` is pushed on the stack. Map takes a list of elements and a quoted program and applies the program to each element. Note that: * There are no variable assignments. * elements are pushed on the stack one by one. * Parentheses are grouped together one or more elements, so that they are treated as a single element and they are not evaluated immediately. * Symbols can be used to perform operations on the whole stack. Unlike more traditional programming languages, in a concatenative programming language there is no inherent need of variables or named parameters, as symbols acts as stack operators that consume elements that are placed in order on top of a stack. ### Downloads * [macOS (x64)]({{$download}}v{{$version}}/{{$github}}_v{{$version}}_macosx_x64.zip) * [Linux (x64)]({{$download}}v{{$version}}/{{$github}}_v{{$version}}_linux_x64.zip) * [Windows (x64)]({{$download}}v{{$version}}/{{$github}}_v{{$version}}_windows_x64.zip) |
