A programming language composed entirely of whitespace.
Nope, I'm not kidding...
NOTE: I am aware that a language called Whitespace (created by Edwin Brady) with a similar concept exists already. I created this as a personal experiment and for fun, I'm not trying to copy the existing Whitespace language, and there are significant differences in syntax and how programs are actually written.
Whitespace is a programming language composed entirely of two characters; space and tab.
The number of spaces you type consecutively correspond to a value. The amount of tabs you type consecutively correspond to an action.
For a full guide of how to write a program in Whitespace, please view the specification.md file. An example "Hello world!" program is provided under helloworld.ws.
$ git clone https://github.com/Romejanic/Whitespace.git
$ cd Whitespace
$ java -jar Whitespace.jar helloworld.wsYou can optionally run Whitespace in a debug mode which will print each step of the program and the value of the current address in memory.
To access this debug, run the program with the --log-actions flag before the file name. This will create a new file called PROGRAMFILE.actions.log (e.g. helloworld.ws.actions.log), with a list of completed actions during execution.
On Windows: Run build.bat
On Mac/Linux: Run build.sh
This will compile the source, place the resulting class files into bin/, and then create a runnable Whitespace.jar.
