compiler's Introduction

Minipascal compiler

Manuel Felipe Pineda - Carlos Alvaro Gonzales

A minipascal compiler for my compliers course on Universidad Tecnologica de Pereira.

this is a free software project, if you want copy/change/modify for academic purposes, feel free to do it (Remember to give credit and thanks to the creators).

if you want to check the code, you can run any of pascal codes in test dir

to run

python <phase>.py path_to_file.pas

where can be: mpaslexer , mpasparser , semantic

  • Lexer returns a list with all tokens of program
  • Parser generate a .png image which will contains the AST for your progam, this file will be create at "path_to_file.png"
  • Semantic checks your progam and advertises you about the problems

to compile

python mpascal.py path_to_file.pas

compiler's Issues

Recursive definitions.

fun foo(x:int)
fun bar(x:int)
y:int;
begin
y := foo(x)
end;
begin
write(x)
end

Until now this definition is wrong.

If then instruction.

fun foo(x:int):int
begin
if (x > 3) then return 3

    /* Error.  The if-statement returns an int.  However, if we
       make it here, the function returns nothing at all. */
end

Recursive definitions.

fun foo(x:int)
fun bar(x:int)
y:int;
begin
y := foo(x)
end;
begin
write(x)
end
