Standard Plug-ins

Vnano Standard Plug-ins are a set of official plug-ins providing basic utility features as functions/variables available in Vnano (VCSSL nano) scripts.

How to Get & Use

These standard plug-ins may be bundled with applications (software) on which scripting features in the Vnano are supported. On such applications, features (functions/variables) provided by standard plug-ins are available by default. However, depending with the purpose of the scripting feature of the application, some (or all) of standard plug-ing may not be bundled. See the document of the application for checking which standard plug-ins are available.

Also, if you want to use standard plug-ins on the application (equipped with the script engine of the Vnano) you developed, get source code of plug-ins from the following repository, and compile it.

Development Repository

Vnano Standard Plug-ins are open source software, being developed on the following repository on the GitHub.
