flexlibs is a library for accessing FieldWorks Language Explorer (FLEx) [1] projects.

flexlibs handles the necessary initialisation of the FLEx engine, and provides a class (FLExProject) for opening a FLEx project and working with its contents.

For the GUI application that runs Python scripts/plugins on FLEx databases see FLExTools [2], which is built on flexlibs.

Requirements

Python 3.8 - 3.13.

Python for .NET [3] version 3.0.3+.

FieldWorks Language Explorer 9.0.17 - 9.3.1.

32-bit vs 64-bit

The Python architecture must match that of FieldWorks. I.e. Install 32-bit Python for 32-bit Fieldworks, and 64-bit Python for 64-bit Fieldworks.

Installation

Run: pip install flexlibs

Usage
