问题
I want to get the content of DataWindow from PBL (PowerBuilder Library) file and edit it in place. The idea is to read the pbl file, and access individual DataWindows to modify source code. Somehow, I have managed to do the first part with PblReader .NET library using IronPython. It allows me to read PBL files, and access DataWindow source code. However it doesn't support modifications. I would like to know if anyone have an idea for editing PBL files?
回答1:
A PowerBuilder application can load a DataWindow from a PBL (doesn't have to be in the library path), modify it, and save it back to the PBL. I've written a couple of tools that do that. PowerBuilder will allow you to modify the DataWindow according to its object model using the modify
method. I don't know why anyone would want to reinvent all of this. I recall seeing Python bindings for PB somewhere. You could get the DW syntax from PB, call out to Python, then save it back in PB. But you'd have to do all the parsing in Python, whereas PB already understands the DW. Finally I'm surprised Terry didn't plug PBL Peeper. You could use PBL Peeper to export the DataWindows, massage them to your hearts's content in Python. then import them back into PB.
