Red programming language This page was last updated: 05/12/2018
I've been looking at this language and I have to say that it IS the future. It puts all of the over bloated resource hungry programming environments to shame.
Red is a single exe, less than one meg in size and needs no dependencies. Red is definitely the way programming should be .... See my Red Apps.
Very similar and inspired by the excellent 'Rebol' scripting language, Red seems to deliver everything a developer needs. You write one script and it runs on/compiles to every platform .... An App developers dream. Though still in its early stages of development, I would say it is already a powerful programming tool. I love it.
 I must congratulate the brilliant 'Nenad Rakocevic' and his devoted team of developers. The amount of work and the dedication needed to get Red to where it is now is awesome. I must also convey the highest regard and respect to these programming guru's ....
Get the Red Language
Go to the Red site: http://www.red-lang.org/p/download.html and download the last stable build. The site has plenty of instructions and tips.
I use Windows, so will show how to get started in Windows .... So: 'Create a new folder' call it 'Redthings' .... now copy the red-063.exe to your 'Redthings' folder. there are a few ways to interpret and/or compile Red scripts .... but for now all you need is a text editor .... Any text editor will do, but lets make things easy .... If you go to: http://www.mikeparr.info/redlang.html and move down to 'Try Ride for Windows' then click on 'you can download it here ' .... then unzip into your 'Redthings' folder and away you go.
Alternatively you could try my simple 'Red' editor with built in interpret and compile options, No setup needed, just unzip and go .... Simple, No Nonsense .... Write, Interpret and Compile ..... Get it here:
Check out the examples below and See my Red 'Beginners Reference Guide' for more.
Also typing 'what' at the Red console prompt will give you a list of all Functions.
