In the Hops component, is it possible to specify the path to the definition as relative to the current file location? Absolute paths would be a nightmare, e.g. when copying a project to another machine or simply when renaming the containing directory.

In a reply to another question, @AndersDeleuran showed me how to get the path of the current script. That allows the construction of relative paths: [Screenshot of definition importing Hops function via relative path] 2024-04-14_document.gh (10.8 KB) 2024-04-14_function.gh (2.3 KB) Personally, …

Aside from ghenv.Component.OnPingDocument().FilePath you could also use ghenv.LocalScope.ghdoc.Path. Same result, just an alternative. import os if definition: root = os.path.dirname(ghenv.LocalScope.ghdoc.Path) path = os.path.join(root, definition + ".gh")

New version! This one works from within clusters: [Screenshot with updated code that works within clusters] 2024-04-16_document.gh (9.1 KB) [image] Martijn Weiland: Aside from ghenv.Component.OnPingDocument().FilePath you could also use ghenv.LocalScope.ghdoc.Path. Same result, just an alter…

Clear, thanks for letting me know! Up untill now I haven’t had the need of using a cluster. Mostly I resort to ghPython/C# within grasshopper or just writing a plugin if I use something repetitively.

May I ask why you want to use a hops component? Also what rhino version are you using, rhino 8 I assume from the other post?

Yes, Rhino 8. I put a lot of definitions now in Hops. Asides from lack of support for relative paths and another quirk , I enjoy Hops. They allow me to split a complex definition into sub definitions. These Hops functions can be thoroughly tested. By comparison, clusters feel fragile. But they have t…

I see, Perhaps interesting as an alternative (in case caching isn’t a hard requirement), is to write the complex definitions as seperate .gha component. Rhino 8 made it quite a bit easier to write custom components, where you previously had to go to VsCode and use the C# template. This post has an…

In the case above you won’t be required to provide paths either. As it’s just another grasshopper component. The main concern would be ensuring that the user has the right version of plug-in installed to run said definition.

Unfortunately, as I found out yesterday, with clusters, it all blows up when actually renaming the containing directory. See my reply in the thread Hops is missing inside some clusters.
