Systems630-Project1

Dependencies

• TypeScript version 1.1.0.1
• Browserify (npm install browserify)
• NodeJS for testing
• Python 2.7.8 for compiling tests
  • python2.7 should be in $PATH

Tested on: Google Chrome 38.0.2125.104 (64-bit)

Features

Supports a subset of Python 2.7.8 bytecode:

• Functions (including keyword and default arguments)
• Condition statements (if and comparisons of integers and booleans)
• The four numeric types: Integer (32 and 64 bit), Long (arbitrary precision), Float and Complex.
  • Certain operations are unsupported, e.g. powers for complex numbers
• Output via printing
  • Spaces are not automatically inserted between elements
• NOTE: This interpreter forces true division. That is, 5 / 2 == 2.5. To force floor division, use the \\ operator à la Python 3.
• Most unary and binary op codes are defined, along with those necessary for loading and storing objects and executing functions.

Usage

Running the Interpreter

• Compile the main JavaScript driver:

$ make main

• Load main.html in your browser of choice
• Click on "Choose File" and upload a .pyc file
• Click "Process File". The output should appear in the Output area.

Running Tests

• Compile the test.js file and the Python tests with Make
• Run the test.js file in node

$ make test
$ node test.js

• Alternatively, follow the "Running the Interpreter" steps and load one of the *test.pyc files from the examples/ directory.

Adding More Tests

• Write the test: testExample.py
• Save it somewhere in the examples/ directory
• Add a new test to test.ts that gives a description for the test and a path to the .pyc file:

test("This is a sample test", "examples/path/to/testExample.pyc");

• Make should be able to automatically compile the test file
