A simple prolog breadth first search interpreter

How to use it

Visit: https://askuri.github.io/PrologBFS/wasm/ or build it from source. Suppose your executable is named "prolog_bfs", type "prolog_bfs program_file" and it will run. WebAssembly: run "start_server.sh" and go to http://localhost:8080/

Install Instructions

Prerequisites

Dependencies:

We develop on Ubuntu Linux. If you use windows or another OS, you might need to change the commands accordingly.

Install

#Boost libraries
sudo apt-get install libboost-all-dev
git clone https://github.com/LhKipp/Prolog_BFS.git
cd Prolog_BFS
./build.sh

Building

Run ./build.sh --help for help on how to build the program

Known Limitations

  1. Only integer arithmetic is supported.
  2. Variables / constant names starting with an underscore are not supported. (This implies that a single "_" as a variable name is not supported)
  3. The only supported built in predicates are ==, ==, is/2 and append/3.
  4. The online version has a limit of 500MB memory. For the offline version there is no memory usage check. If an endless program has been supplied, the program won't stop allocating memory. Make sure to kill the program before all memory is exhausted.

Contributors

  • Martin Weber (https://github.com/askuri). Created the web frontend, tested the program, created documentation, updated the build scripts, gave constructive feedback, found some bugs. Big thanks.
