C - Stacks, Queues - LIFO, FIFO

Description

Monty 0.98 is a scripting language that is first compiled into Monty byte codes (Just like Python). It relies on a unique stack, with specific instructions to manipulate it. The goal of this project is to create an interpreter for Monty ByteCodes files to manipulate stacks.

List of Files

File Name	Description
monty.h	Declaration of all functions to be used in the program, as well as libriaries and global variables
main.c	Principal function
operations.c	Contains the functions to be used
errors_file.c	Contains all the posibles exits to the program
executer.c	Contains the functions to open and read the file to execute
opcodes.c	Contains the functions to call the functions to be execute
helper_functions.c	Contains the functions like _strcmp and others, to be called in another file
Makefile	Contains the compilation and clear functions
generate_authors.sh	a file with all the names and corresponding emails of individual contributors
bf	A directory that contains some files written in brainfuck
bytecodes	Directory with the tests of the opcode

Usage

Compilation

To compile the program this command has to be executed:

$ make all

This will create a compilation file, its name is montyfile. You can run this file in your terminal with the next command:

$ ./montyfile <file>

Format

Format for user to write in "testfile.m": opcode argument

Examples

$ cat opcodetestfile.m

push 1

push 2

push 3

pall

$ ./montyfile opcodetestfile.m

3

2

1

Allowable opcodes and what they do

Opcode	Functionality
push	Add element to the 'top' of stack and 'end' of queue
pop	Remove element from 'top' of stack and 'end' of queue
pall	Print every member of the structure
pint	Prints the member value at the top of stack
swap	Swaps the order of the 1st and 2nd elements in stack
add	Add top two member values
sub	Subtract the top element from the 2nd top element
div	Divide the 2nd element by the top element
mul	Multiply the top two elements of the stack
mod	The remainder when the 2nd element is divided by the top element
comment	There is the ability to parse comments found in bytecode ->'#'
nop	Opcode should do nothing
