# ERPLAG Compiler, Group 02
This repository contains the toy-compiler created as part of requirements for the course **CS F363: Compiler Construction** at BITS Pilani, Pilani Campus in Spring 2023 under [Dr. Vandana Agarwal](https://universe.bits-pilani.ac.in/pilani/vandana/profile). Our team (**Group 2**) scored the highest among all groups which were part of the course.
> See marks distribution for our team [here](./docs/Marks.pdf)
## Features supported by the language
> [Click here](./docs/language%20specifications.pdf) for language specifications.
- The language `ERPLAG` is a strongly typed language with primitive data types as **integer** and **floating point**.
- It also supports two other data types: **boolean** and **arrays**.
- The language supports arithmetic and boolean expressions.
- The language supports assignment statements, input/output statements, declarative, conditional, iterative, and function call statements.
- The language supports the modular implementation of the functionalities.
- Functions can return multiple values. The function may or may not return a value as well.
- The scope of the variables is static and the variable is visible only in the block where it is declared.
## Dependencies
1. Ensure you have `gcc`, version 5.0 or greater, installed.
> `gcc` version can be checked via `gcc --version` command on terminal.
2. Ensure you have `nasm`, version 2.14.02 or greater, installed
> `nasm` version can be checked via `nasm --version` command on terminal. You can install `nasm` via `sudo apt install nasm`
## Instructions to run
`makefile` has been provided with the code along with some sample test cases.
Run the following commands.
```bash
$ make
// The output to this should be
gcc -c -g driver.c
gcc -c -g parser.c
gcc -c -g lexer.c
gcc -c -g trie.c
gcc -c -g stackADT.c
gcc -c -g Set.c
gcc -c -g ast.c
gcc -c -g symbolTable.c
gcc -c -g intermedCodeGen.c
gcc -c -g codegen.c
gcc -Wall driver.o parser.o trie.o lexer.o Set.o stackADT.o ast.o symbolTable.o intermedCodeGen.o codegen.o -g -o compiler
```
Once all the files have been compiled correctly, run
```bash
$ ./compiler
```
To run the `.asm` file, use this command
```bash
$ nasm -f elf64 -o code.o && gcc -no-pie code.o -o code
$ ./code
```
## Sample `ERPLAG` Code
```
<<>>
start
declare x, y, z:integer;
declare a, b, c:integer;
a:= 5;
b:= 9;
get_value(x);
get_value(y);
z:= x + y*b +(a-b)*y+ a*2 - b*x;
print(z);
end
```
## Sample Output
```
Input: Enter an integer value
2
Input: Enter an integer value
3
Output: 9
```
