py2qasm cli tool

[dakk]

Create a cli tool in the qlasskit/tools package called py2qasm that receives a python script (file or stdin) in input and outputs qasm code. The python script should contain at least one qlassf function.

• If not specified by --input-file/-i, read from stdin (-).
• If not specified by --entrypoint/-e, func_name is the last qlassf defined.
• If not specified by --output/-o, output to stdout
• If not specified by --compiler/-c use internal compiler (or tweedledum)
• If not specified by --qasm-version/-q use v3 qasm version

py2qasm -i pyfile [-e func_name] [-c internal] -o qasm_file

Provide also:

• -h\--help for usage
• -v\--version for qlasskit version

Requirements:

• Code should be placed on qlasskit/tools
• Use argparse for argument parsing
• Use qlasskit.tools.utils for getting qlassfs from file / string
• A test case must be provided in test_tools.py
• Keep an eye on issue py2bexp bool expressions exporter #28

Hi, @dakk !
I'd like to work on this issue as a part of unitaryhack.

[dakk]

Hi, wonderful, please go on and let me know if you need anything.

[CRTejaswi]

Hi, @dakk! Can you please share a couple of sample python files to be transpiled?

[dakk]

There is one in the test_tools file linked above. If you need more you can find some example code in test cases and in the docs; let me know if you need something different

I'll start working on this issue

Thank you for the contributions @tomv42 ; I hope you enjoyed working on the qlasskit library: if so, please "star" the project, and tell your quantum friends about qlasskit :)

[tomv42]

This was my first experience in open source and I really enjoyed working on qlasskit. I learned a lot. Also, I've already starred the project :)

Great!

@tomv42 Also, if you have an idea about a quantum algorithm to be implemented in qlasskit, you can propose it on this issue #32 still open for unitary hack.

@tomv42 it doesn't look like you registered for unitaryhack, send me an email at kallie@unitary.fund if you want the bounty.
