Unified Scripting in Studio

Python scripting is now unified, enabling better solutions.

Pervasive Python Across All Valentina Products

With Valentina Release 14, Paradigma Software introduced unified JavaScript and Python engines in Valentina Reports, ValentinaDB Stored Procedures and Valentina Forms. Previously, different products used different engines which lead to some inconsistencies in how scripts were executed. Now, with a unified engine, the behavior is consistent and reliable across all parts.

The Python engine is now integrated with various aspects of Valentina Studio, including Forms and Scripts, Valentina Reports, and even the ValentinaDB engine itself. This enables a more powerful development experience by allowing you to leverage Python for various tasks.

Valentina Studio PRO	Valentina Server	Valentina Reports	Valentina Forms
Visual Designer & Scripting: Reports Visual Designer & Scripting: Forms Test Stored Procedures Locally	Python Stored Procedures Python User Defined Functions Reports Server ValentinaDB Server	Python for Scripting Reports ADK for Xojo	Python for Scripting

Omegabundle for Xojo 2024 includes all of these tools: Valentina Studio PRO, Valentina Server Unlimited, Valentina Reports ADK for Xojo and ValentinaDB for Xojo.

Integrate Python Modules

Valentina Studio offers comprehensive Python integration for your scripts, including module support for:

built-in modules
third-party modules
custom modules

Valentina Studio's Python integration expands its capabilities by allowing you to utilize modules installed within virtual environments (venv). These isolated environments, created using tools like venv, keep project-specific dependencies separate from the system-wide Python installation. Valentina Studio can access modules installed within activated venv environments, enabling you to leverage specific libraries for your scripts without affecting other projects or the global Python environment. This ensures clean and organized development by allowing you to manage project dependencies independently.

Built-in Modules	Third Party Modules	Custom Modules
You can directly utilize built-in Python modules for various functionalities, such as sys. import sys As of Omegabundle for Xojo 2024, the number of built in Python modules is 164. Open the complete list of modules	Install and use of third-party libraries. This grants access to specialized tools beyond the built-in modules. An example of the installation of the Numpy library: pip install numpy After the installation you can start using a module, make sure to provide a path to the modules folder: import sys if '/path/to/site-packages/' not in sys.path: sys.path.append('/path/to/site-packages/') import numpy as np a = np.array([6, 7, 8]) The sys.path variable persists for the duration of the application’s runtime. Therefore, if you load modules from various locations, it is essential to ensure that the location of the current script is placed at the beginning of the list.	You can develop custom Python modules for improved code organization and reusability. This combined approach allows you to leverage the vast Python ecosystem and create powerful, tailored scripts within Valentina Studio.

After the installation you can start using a module, make sure to provide a path to the modules folder:

import sys
if '/path/to/site-packages/' not in sys.path:
    sys.path.append('/path/to/site-packages/')
 
import numpy as np
a = np.array([6, 7, 8])

The sys.path variable persists for the duration of the application’s runtime. Therefore, if you load modules from various locations, it is essential to ensure that the location of the current script is placed at the beginning of the list.

This combined approach allows you to leverage the vast Python ecosystem and create powerful, tailored scripts within Valentina Studio.

Due to a Windows-specific implementation detail where binary packages depend on a Python DLL, and Python is built-in in VKernel, the dependency is not satisfied, and the package can't be loaded. Other platforms are not affected.

Signal-Slots for Python

Signal-slots for objects in Valentina Forms and Valentina Reports can be scripted with Python.
