Enable LVPROJ to specify VI search path.
- A "path" may override or be composited with the path specified in its parent environment (the IDE or another project).
- A "path element" may be a directory or file, or a recognized LabVIEW type (lvproj, lvclass, lvlib, virtual folder, etc.) that can be resolved to a working environment directory or file.
- A "path element" that resolves to a directory may be searched at just the top-level or it may be recursively searched.
If no project search path is specified, default to current VI resolution behavior.
If a project search path is specified, resolve VIs by name within the scope of that path. If resolution fails and parent scope is available (composition rather than override), search the parent scope too.
Straw use
Given ProductA dependent on, but not containing CommonLib. When CommonLib moves for arbitrary reasons, the developer shouldn't have to (tediously) reconnect each individual component referenced. It should suffice to modify ProjectA's VI search path to reflect CommonLib's unique and perhaps relative path location. Perhaps, the "Find the VI" dialog should sport an option to modify the VI search path as an alternative to specifying the precise VI.
If I'm revising a product to use Library 2, I want to be able to checkout the product based on Library 1 and then re-point the project search path to pick up VIs from Library 2. A VI should resolve in the scope (possibly upward recursive) of the project search path. If that fails, then it should prompt--relative or absolute pathing within the VI should have no precedence when project search path is specified.
Available in LabVIEW NXG 1.0. A project will only link to libraries based on installed packages, or components that are currently added to the project.
