multithreading-intepreter

Intepreter that executes SimpleScript programs with multithreading. University project [no.4] for Concurrent Programming (Fall 2017).

Description

Execute programs written in a custom programming language called SimpleScript. Those programs will be run from command line and may have multiple arguments. The intepreter can run multiple programs at the same time using multithreading. Programs with same variable name will have same memory on the system, so the intepreter is responsible to manage common memory.

SimpleScript syntax

Prerequisites

• C
• Make (sudo apt install make)
• GCC (sudo apt install gcc)

How to run

1. On terminal run make to build the executable C program.
2. Start the intepreter with ./hw4b.
3. To run a program enter run inputFile.txt [arg0] [arg1] [argN]
4. Enter list to see every program's status and ID.
5. Enter kill [ID] to stop a program.
6. Enter exit to stop the intepreter.

Input tests

1. init.txt is a dummy program to make sure everything is working. It test if variables are storing value correctly.
2. sum.txt is a program that takes as input N a number and return the sum of every number from 1 up to N.
3. producer.txt and consumer.txt are the the classic multithreading problem of producer/consumer, where the one side add(produce) items(+N values) on a common buffer(variable) and the other side decrease(consume) those items(values).
