# NYU Compiler Construction CSCI-GA.2130/Spring 2021: Programming Assignment 2
|
||
|
|
|
||
|
|
This assignment is adapted from https://github.com/cs164berkeley/pa2-chocopy-semantic-analysis with the authors' permission.
|
||
|
|
|
||
|
|
See the PA2 document on Piazza for a detailed specification.
|
||
|
|
|
||
|
|
## Quickstart
|
||
|
|
|
||
|
|
Run the following commands to compile your analyzer and run the tests:
|
||
|
|
```
|
||
|
|
mvn clean package
|
||
|
|
java -cp "chocopy-ref.jar:target/assignment.jar" chocopy.ChocoPy \
|
||
|
|
--pass=.s --test --dir src/test/data/pa2/sample/
|
||
|
|
```
|
||
|
|
|
||
|
|
The dot in `--pass` makes the compiler skip parsing and go straight to semantic analysis.
|
||
|
|
`--pass=.s` uses your (`s` for `student`) analyzer to perform semantic analysis on a preparsed input (in this case, the `.ast` files under `src/test/data/pa2/sample/`).
|
||
|
|
With the starter code, only two tests should pass.
|
||
|
|
Your main objective is to build an analyzer that passes all the provided tests.
|
||
|
|
|
||
|
|
`--pass=.r` uses the reference (`r` for `reference`) analyzer, which should pass all tests.
|
||
|
|
|
||
|
|
In addition to running in test mode with `--test`, you can also observe the actual output of your (or reference) analyzer with:
|
||
|
|
```
|
||
|
|
java -cp "chocopy-ref.jar:target/assignment.jar" chocopy.ChocoPy \
|
||
|
|
--pass=.s src/test/data/pa2/sample/expr_unary.py.ast
|
||
|
|
```
|
||
|
|
|
||
|
|
You can also run both passes on the original `.py` file:
|
||
|
|
```
|
||
|
|
java -cp "chocopy-ref.jar:target/assignment.jar" chocopy.ChocoPy \
|
||
|
|
--pass=rr src/test/data/pa2/sample/expr_unary.py
|
||
|
|
```
|
||
|
|
|
||
|
|
Once you merge your parser code from assignment 1, you should be able to use `--pass=ss`.
