Instructions to run

To extract tokens using lexer:

src/parser.py -l <input_file>

To parse a file - Generates the parse tree in "graphs" folder with the same name

src/parser.py -p <input_file>

To clean the temporary files and graph

make clean

Tests

This test file should be used for lexer:

• LexerTest.java

These test files should be used for parser:

• BinaryConverter.java
• Factorial.java
• ObjectVarsAsParameters.java
• SimpleWordCounter.java
• StringExample.java

In case you want to use more complicated testcases, you can use these (provided a 15 MB png file opens on your computer):

• EightQueens.java
• RecursionExampleDirectory.java

Dependencies

• python2 or python3
• pydot
• ply

Acknowledgments:

• We have modified the lexer and parser from https://github.com/musiKk/plyj.
• Graph has been generated using pydot library.
• For scanner and parser, we are using ply (python-lex-yacc).
• The tests have been taken from https://www.cs.utexas.edu/~scottm/cs307/codingSamples.htm.
