simple-mini-pascal-compiler

mini (very mini) pascal compiler written using flex, bison, c and MIPS

###Instructions

• install flex and bison if you haven't already (Google search "install flex and bison" if you are having trouble)
• run make
• using the test files run ./project3.2 /optionalpath/nameoftestfile.pas
• the output of this will tell you if your file is syntactically correct and will generate a "nameoftestfile.s" file
• once this file is generated you can run it in Mars to execute your code!

###Dependencies

Instructions on how to download the first two can be found relatively easily online

• flex
• bison
• mars
  • open the *.s file and hit f3 to assemble the code then f5 to run it

Note: In Ubuntu, flex and bison can be installed using apt-get
$sudo apt-get update
$sudo apt-get upgrade
$sudo apt-get install flex bison

###Disclaimer Keep in mind that the functionality is very limited. Simple statments such as if...then...else with basic integer relation operators, addition, multiplication, and division are all accepted in the current version. It's best to assume that all other functionality is unsupported.

######TODO Currently it does not support while loops.
Nesting if...then...else logic not been tested.
String and character manipulation is unsupported (or at least untested).
...and much more...
