WARNING!! THIS LANGUAGE IS IN DEVELOPMENT (AND FOR LEARNING PURPOSES). ANYTHING CAN CHANGE AT ANY MOMENT.

🖐 SLAP stands for "SLow And Powerless." And I hope to make it "Powerful" someday.<br>

SLAP is a dynamically- and strongly-typed, object-oriented programming language. Its syntax is a member of the C family with a bit of difference.

Example

As of March 2022, you can write pretty decent, small programs in SLAP.

Note: The SLAP-to-JS transpiler is in progress (see compiler branch).

Installation

On Linux/macOS, you may be able to run the following commands to install SLAP.

$ git clone https://github.com/bichanna/slap.git
$ cd slap
$ chmod +x ./build.sh 
$ ./build.sh         # The SLAP Vim highlighter automatically gets installed

For Windows, I haven't written bat version of build.sh, so you have to manually compile the source code.

$ nimble build --multimethods:on -d:release

Then, mark it as an executable file if necessary, and try running slap --version.

$ slap --version
SLAP 0.0.3

You may want to test current SLAP you just built before running your programs.

$ nimble test
