SANKLAk : A python Compiler

Abstract

SANKLAK is a compiler for statically typed subset of python programming language. The lexer and the parser for this compiler is written using Flex and Bison utility while the semantic actions, helper functions and linkages are implemented in C++.

Running Instructions

Generating dot output

All the source codes are present in the src directory. Running the Makefile generate the executable python. When provided with an input python program, the following commands will generate an output dot file in the src/ directory:

$ cd src
$ make
$ ./python -i test.py -o output.dot

Following command line arguments are supported by the executable:

Usage: ./python [options]     

Commands:
----------
-h, --help 					             Show help page
-i, --input <input_file_name> 			 Give input file
-o, --output <output_file_name>			 Redirect dot file to output file
-v, --verbose 					         Outputs the entire derivation in command line

The input python program can also be passed directly without the -i or --input flag. By default, the generated output file is named file.dot.

Generating the AST graph

Further, to generate svg/png/pdf graph of the AST tree, run the following command:

$ dot -T<svg/png/pdf> output.dot -o AST.<svg/png/pdf>

---

A successful execution example can be:

$ cd src
$ make
$ ./python test.py
$ dot -Tpdf file.dot -o AST.pdf
$ make clean
