stklng is a stack based, minimalistic interpreted programming language
You need the c3 compiler https://github.com/c3lang/c3c
then you can simply run
$ make
or
$ make install
to install it to /usr/bin
so it's on your path
download the release (linux only for now)
afterwards you can run .sl files with
$ path_to_stklng_executable/stklng-linux64 path/to/file.sl
