# Parsing
 | 
				
			||||
 | 
				
			||||
Your parser passed all tests, including the hidden ones, congratulations!  Nice catch on the multiline string, which is a missing piece in the ChocoPy specification. Looking forward to your next project.
 | 
				
			||||
 | 
				
			||||
# Testing
 | 
				
			||||
 | 
				
			||||
Good work in the challenging cases in `good.py` like nested functions and class methods, and in `bad.py` like statements in class definition.
 | 
				
			||||
 | 
				
			||||
It looks like you haven't added your own tests besides those in `good.py` and `bad.py`. We recommend pinning down more of your functionality with short, targeted tests in the future.
 | 
				
			||||
 | 
				
			||||
# Process
 | 
				
			||||
 | 
				
			||||
We generally recommend using pull requests over directly pushing into the master branch, especially when you want to work in parallel. As the project becomes more complex, you may appreciate the benefits of a more structured SDLC process.
 | 
				
			||||
 | 
				
			||||
# Code
 | 
				
			||||
 | 
				
			||||
Your code is clean and readable, with consistent naming convention and proper amount of comments. Well done.

# Tests for PA1: ChocoPy Parser
 | 
				
			||||
 | 
				
			||||
Clone a student repository:
 | 
				
			||||
```
 | 
				
			||||
TEAM="team"
 | 
				
			||||
git clone --branch=pa1final \
 | 
				
			||||
    https://github.com/nyu-compiler-construction/pa1-chocopy-parser-${TEAM}
 | 
				
			||||
```
 | 
				
			||||
 | 
				
			||||
Build it:
 | 
				
			||||
```
 | 
				
			||||
cd pa1-chocopy-parser-${TEAM}
 | 
				
			||||
mvn clean package
 | 
				
			||||
```
 | 
				
			||||
   
 | 
				
			||||
Clone the tests _into_ the student repository:
 | 
				
			||||
```
 | 
				
			||||
git clone https://github.com/nyu-compiler-construction/pa1-tests
 | 
				
			||||
```
 | 
				
			||||
 | 
				
			||||
Run the tests:
 | 
				
			||||
```
 | 
				
			||||
./pa1-tests/run-tests.sh 
 | 
				
			||||
```

 | 
				
			||||
 *
 | 
				
			||||
 * The rules provided below parse expressions of the form <INT> + <INT> + ... 
 | 
				
			||||
 * You can re-use these rules or edit them as you wish. The start rule
 | 
				
			||||
 * should return a node of type Program.
 | 
				
			||||
 *
 | 
				
			||||
 * Tips: Production rules are usually followed by action code that will be
 | 
				
			||||
 * copied to the generated parser to be executed immediately after a reduce
 | 
				
			||||
 * operation; that is, when a production rule has been matched. You can name
 | 
				
			||||
 * a nonterminal or terminal symbol in a production rule using the colon
 | 
				
			||||
 * notation, e.g. expr_stmt ::= expr:e, to get the AST node for the matched
 | 
				
			||||
 * expression. In the action code, `e` will be a variable of whatever type
 | 
				
			||||
 * has been declared for the corresponding nonterminal, such as `Expr`.
 | 
				
			||||
 * Therefore, you can construct an AST Node of type `ExprStmt` with `e` in the
 | 
				
			||||
 * constructor: `new ExprStmt(exleft, exright, e)`
 | 
				
			||||
 *
 | 
				
			||||
 * The variables `exleft` and `exright` are automatically generated by CUP
 | 
				
			||||
 * and contain Location objects for the start and end of the expression `e`.
 | 
				
			||||
 * You can collect start and line number info for AST nodes by taking the
 | 
				
			||||
 * location of the left end of the leftmost symbol in a rule and the
 | 
				
			||||
 * location of the right end of the rightmost symbol. The auto-generated
 | 
				
			||||
 * variables have names `<sym>xleft` and `<sym>xright`, where <sym> is the
 | 
				
			||||
 * name given to the symbol using the colon notation.
 | 
				
			||||
 *
 | 
				
			||||
 * When you have nonterminals that are lists of things, e.g. List<Stmt> or
 | 
				
			||||
 * List<Declaration>, it is helpful to get the leftmost and rightmost
 | 
				
			||||
 * source location from within this list; we have provided some utility
 | 
				
			||||
 * functions below to do just that.
