What?

Naylang is the new interpreter, runtime and debugger for a subset of the Grace Programming Language. It’s still a work in progress, but it has some great features already!

How?

To use Naylang, just download the executable for the latest release and start it up in a terminal!

If you’d rather compile it from source click me!

Commands

For now, Naylang accepts three kinds of commands:

• load (or l) <path>: Open the file in <path>, execute it, and show the resulting environment.

• exec(or e) <code>: Execute the code and show the resulting environment.

• print (or p) <expression>: Execute the expression and show the result.

Here’s an example execution of Naylang:

Want to contribute?

Naylang is written entirely in modern C++14.
It uses ANTLR4 for parsing, CMake as a build system and Catch as a testing framework.

If you’d like to contribute to this project, you are more than welcome to.
Feel free to submit an issue,

fork the main repo and submit a pull request with your improvements, or even shoot me an email (blorente@ucm.es) if you want some direction on where to begin.

Compilation instructions

Naylang uses standard out-of-source compilation with CMake.
It requires at least version 3 of CMake and a compiler that supports C++14 (for example, GCC6.x).

When all those dependencies are installed, just download the repo (git clone https://github.com/blorente/naylang) and a simple sequence of commands should suffice to run the tests:

cd /root/of/repo
mkdir
build && cd build  
cmake ..
make -j antlr4cpp antlr4cpp_generation_naylang  
cmake ..  
make -j
cd tests  
chmod +x ./tests  
./tests
