Python Assembler

Information

The purpose of this project was to create a python assembler in C language. We had produced 3/4 deliverables, with test functions.

First Part

The purpose of the first part was to create a regular expression analyzer with the Extended Backus-Naur Form language, to see if an expression is matching with a regular expression.

Second Part

The main purpose of this part was to create a lexer in order to analyze the syntax of an assembly file. Here is an exemple for this python file :

s=0foriinrange(5):
s+=s+1print("\n")

# Start pyc-objdump output.set version_pyvm 62211.set flags0x00000040.set filename "5.py".set name "<module>".set stack_size 4.set arg_count 0.interned"s""range""i""<module>".consts051"\n"	None.names"s""range""i".text.line 1	LOAD_CONST 0	# 0	STORE_NAME 0	# "s".line 3	SETUP_LOOP label_2	LOAD_NAME 1	# "range"	LOAD_CONST 1	# 5	CALL_FUNCTION 1	GET_ITER label_0:	FOR_ITER label_1	STORE_NAME 2	# "i".line 4	LOAD_NAME 0	# "s"	LOAD_NAME 0	# "s"	LOAD_CONST 2	# 1	BINARY_ADD 	INPLACE_ADD 	STORE_NAME 0	# "s"	JUMP_ABSOLUTE label_0label_1:	POP_BLOCK .line 6label_2:	LOAD_CONST 3	# "\n"	PRINT_ITEM 	PRINT_NEWLINE 	LOAD_CONST 4	# None	RETURN_VALUE # Disassembled Wed Oct 1815:52:062023

Here the syntax is true.

Third Part

The purpose of this part was to create a parser which can create a py_obj of our assembly python file in order to analyze the grammar of our code.
