README
LDPL in Rust
LDPL is a powerful compiled programming language designed from the ground up to be excessively expressive, readable, fast and easy to learn. It mimics plain English, in the likeness of the good parts of older programming languages like COBOL, with the desire that it can be understood by anybody. LDPL was designed to run on Unix systems, including AMD-64 Linux, macOS, ARMv8 Linux, Android Termux and both Intel and PowerPC OS X (tested from Tiger 10.4 onwards). It even supports UTF-8 out of the box.
— The Official LDPL Repository
This is an experimental LDPL 4.4 compiler written in Rust. Like the official compiler, LDPL code is translated to C++ code and then compiled into a standalone binary. Generated code should be 100% compatible with the official compiler, meaning LDPL-RS should work just fine with regular LDPL extensions.
Building It
LDPL-RS requires make, cargo, and Rust to build, and a C++ compiler to use.
Once you've got all that, building is a breeze:
git clone git://github.com/xvxx/ldpl-rs
cd ldpl-rs
make
If that works, you've successfully built an ldpl-rs binary that you
can use to compile any of the official LDPL examples:
git clone -b 4.4 git://github.com/lartu/ldpl
./ldpl-rs ldpl/examples/99bottles.ldpl
You can also use the "run" command to build and run a file in one go:
./ldpl-rs run ldpl/examples/99bottles.ldpl
99 bottles of beer on the wall...
To take it with you, just copy ldpl-rs to /usr/local/bin or
something else in your $PATH.
Status
This project is in its infancy, but can compile simple LDPL programs. It supports all LDPL 4.4 statements, including C++ extensions, and can compile and run all the examples that shipped with LDPL 4.4. It can also compile Gild and ldpl-todo.
It passes 11 of 12 of the official LDPL tests.
However, these features are currently unsupported (but coming soon):
- nested collections (NUMBER LIST LIST LIST)
- OF syntax (LIST OF NUMBERS)
To run the tests, clone this project (instructions above) and run:
make test
