vfp2py's Introduction

vfp2py

vfp2py is an attempt to create a tool to automatically create python code from foxpro 9 code.

Many but not nearly all commands are currently supported with missing commands to be added as need arises. Conversion can be done on individual prg files or whole projects pjx files.

Features

Translates code comments
Handles preprocessor commands
Support for reading and writing dbf files via Ethan Furman's dbf package
Many functions are inlined in the generated python code.
Many complex functions and commands are available through a runtime - vfpfunc.py
Somewhat functioning gui using PySide

Future work

Add more commands to parser
Improve gui
Rework scoping to facilitate operation of some commands.
Add missing code conversion for some commands currently supported by parser
Add more runtime functions
Put package on pypi for easier install
Speed up parsing

Installation

python -m pip install vfp2py

Usage

    $ vfp2py --help
    usage: vfp2py [-h] [--logging] infile outpath [search [search ...]]
    
    Tool for rewriting Foxpro code in Python
    
    positional arguments:
      infile      file to convert - supported file types are prg, mpr, spr, scx,
                  vcx, or pjx,
      outpath     path to output converted code, will be a filename for all but
                  pjx which will be a directory
      search      directory to search for included files
    
    optional arguments:
      -h, --help  show this help message and exit
      --logging   file to convert

To convert a file simply run vfp2py --logging input_file.prg output_file.py or vfp2py --logging input_project.pjx output_directory

vfp2py's Issues

Runtime errors

Hi again! Was trying to convert a file over and got some errors that spit out. I'm assuming the errors I'm getting are from something I approached incorrectly, but here is the full output for development reference. I've got some files that are 8 thousand lines long of FoxPro so hoping we can get this figured out!

Let me know if there's anything I can do to help!

I'm getting this error when I run `python setup.py test`

ImportError: attempted relative import with no known parent package

I am very new to Python so maybe the error I am getting could look silly and might have an obvious solution but I am struggling to solve it. I downloaded the vfp2py-master zipped file and extracted it in the Python folder in my c drive. Somehow managed to install the setup.py and now I am trying to run vfp2py where I get the below error:
File "C:\Users\DPA524\AppData\Local\Programs\Python\Python37-32\vfp2py-master\vfp2py_main_.py", line 7,
in
from . import vfp2py
ImportError: attempted relative import with no known parent package

Please guide me.
Thank you.

`SET PROCEDURE TO` cannot be parsed

The expression SET PROCEDURE TO cannot be parsed by this library, though Visual FoxPro accepts it.

Relevant part of codebase:

vfp2py/vfp2py/VisualFoxpro9.g4

Line 290 in 4e18f95

| setword=PROCEDURE TO specialExpr (',' specialExpr)* ADDITIVE?

Syntax Error - Possible Missing Grammar Entry?

First, thank you for publishing the project. I haven't quite got it working for what I need just yet, but even so it's already saved me a headache and a half.

I'm getting a syntax error during conversion of this line: CALCULATE MAX(LEN(ALLTRIM(memofile))) TO ln

Looking at a couple of the closed issues, I'm assuming this is due to either not having an entry for CALCULATE in the grammar, (if I'm reading this correctly, it looks to be commented out) or not having an entry for the added TO clause.

I looked at adding it myself, but after a cursory look over the project I'm fairly sure that meddling with any of the source would be well beyond my pay grade. That said, I'm a Python programmer by trade so if you let me know the rough basics of adding the requisite information I'll happily make the updates and submit a PR when I have everything working.

Install Issue

Hi there! I'm currently trying to get this running on mac OS using terminal, Py3, and pip3, I got the following error below but was unsure exactly if this error is more a user error of software error, please let me know, thank you!

Syntax: SET UDFPARMS to VALUE

I'm not sure but this just feels like an issue because I'm on mac or a bad package version.
Thoughts?
