RIGAL

Rigal is compiler construction language developed at the University of Latvia, Institute of Mathematics and Computer Science in 1987. The main data structures are atoms, lists and labelled trees. The control structures are based on advanced pattern matching. All phases of compilation, including parsing, optimization and code generation, can be programmed in this language in short and readable form.

This repository includes RIGAL to C compiler, examples, detailed language description and user guide.

Prerequisites

sudo apt-get install build-essential gcc-multilib csh

Build

This will build RIGAL executables and put them into bin/ directory

cd src
make

After build the folder with executables (bin/) contains the following executables:

rc - checks and compiles RIGAL file

ic - interprets intermediate RIGAL code

v - viewer for RIGAL data saved in file

rig_lint - RIGAL Lint (data type checker)

Install on Debian/Ubuntu Linux as package

sudo dpkg -i distr/rigal_4.45.1_amd64.deb

Install (manually, from source)

To install you may compile and add the folder with executables (bin) to the $PATH environment variable

cd src
make
export PATH="<rigal-path>/bin:$PATH
