8005-Programming-Language

What the 8005 Microprocessor Instruction Set Looks like

Currently, Panda does not support functionality to compile some code into some of these instructions but this has been provided as a reference

Installation

Installing Panda

To install Panda, perform: npm i 8005-panda-lang -g

Voila! You have successfully installed Panda!

Usage

Running Panda interpreter

• To run the Panda interpreter, perform panda

• To quit the Panda interpreter and retrieve the machine code from your inputted Panda code, perform quit; in the interpreter

Compiling Panda files

• Valid Panda files have the .pan file extension
• To compile a .pan file, perform panda fileName.pan

Details

Baseline Features

• My programming language allows users to use basic declaration statements with addition and subtraction

• My compiler successfully parses the code written in my programming language and prints out all the 8005 machine code

• My programming language is elegant and easy to use

• My programming language allows users to use the print as a number function

The Grammar/Syntax

Keywords

• "new" = Variable Declaration
• "print" = Print as unsigned char
• "printAsChar" = Prints a decimal value as it's ASCII equivalent

Operators

• "=" = Assignment
• "-" = Decrement
• "+" = Increment

Terminals

• " " = Whitespace
• ";" = End of statement

Functions

• "print" = Print

Documentation

HOW TO: Declarations

Samples of valid variable declarations are listed below

new variableName1 = 13;
new variableName2 = variableName1;
new variableName3 = variableName1 + 3;

Restrictions in Panda for declaring variables

• Inability to assign a value to more than 2 values in a binary expression
• Only numerical values

Things to keep in mind when declaring variables in Panda

• Make sure that you don't have variables which exceed over 256 or are under 0 otherwise the code will parse but you will have buggy machine code

• Make sure you don't use floats in your code

• Make sure there is no space between the last part of the statement and semi colon

HOW TO: Assignments

Samples of valid variable assignments are listed below

variableName1 = 13;
variableName2 = variableName1;
variableName3 = variableName1 + 3;

Restrictions in Panda for assignments

• Inability to assign a value to more than 2 values in a binary expression
• Only numerical values

HOW TO: Print as Int

Samples of valid print calls are listed below

print 13;
print variable;

Restrictions in Panda for print

• Inability to print binary expressions
• Only numerical values

Things to keep in mind when printing in Panda

• Make sure that you don't have variables which exceed over 256 or are under 0 otherwise the code will parse but you will have buggy machine code

• Make sure you don't use floats in your code

• Make sure there is no space between the last part of the statement and semi colon

HOW TO: Print Int as Char

Samples of valid printAsChar calls are listed below

printAsChar 65;
printAsChar variable

Restrictions in Panda for printAsChar

• Inability to print binary expressions
• Only numerical values

Things to keep in mind when printing as char in Panda

• Make sure that you don't have variables which exceed over 256 or are under 0 otherwise the code will parse but you will have buggy machine code

• Make sure you don't use floats in your code

• Make sure there is no space between the last part of the statement and semi colon

Final example

test.pan

new i = 13;
print i;

i = i + 60;
printAsChar i;

In your terminal, perform: panda test.pan

We're working on some spectacular things with Panda Lang. Our current focus at the moment is ---Conditionals---
