MetaHopper

Information

Welcome to Metahopper - a tool for controlling Grasshopper with Grasshopper :)

This library contains a number of components and commands for querying and manipulating Grasshopper components dynamically. You can retrieve components and objects based on their type, their library, the group they're in, or by selecting them directly - or even get all the objects in a document at once. You can then retrieve information about these components + parameters, the libraries they belong to. You can also manipulate objects directly: enabling/disabling, turning preview on and off, changing the color of groups, the text and size of scribbles, and the shape of sketch objects.

MetaHopper also adds a new menu to the Grasshopper document editor, that wraps up several functions:

BestPracticize Selection lets you pick a group and auto-insert params for all the inputs and outputs coming into/out of the group. This makes for nice, tidy functional groupings that make your Grasshopper code easier to read.

Save Snippet improves on an earlier script I released - it lets you select any group of components + objects and save them as a single user object - without needing to cluster them. This is useful when you want things saved that have internal UI elements - like a graph mapper or slider for instance - that you want to be able to manipulate with the reusable chunk of code you're saving.

Bottleneck Navigator opens up a window that lets you see all the components in your definition, sorted by their "Runtime" - how long it took them to execute. You can click on any item in the list and zoom to it instantly - so that you can find opportunities for optimization in your definition.

Document

Param Info

Gets information about param objects

Assembly Info

Gets information about an assembly

Component Info

Get information about a component object. Retrieve components with Document Info, Get Attached Component, or Get Selected Component.

Document Info

Get information about the GH document and its components

Object Retrieval

Get Groups

Get all groups in the document

Get Connected Objects

Gets all components and params connected to this component

Get Objects of Same Library

Utility

Best Practicizer

Takes a selected group and inserts input and output params at both edges for any data that goes outside the group.

Highlight Objects

Set Object Value

Tries to set the value of an object. What value it sets varies by type - it sets a slider’s numeric value, a panel or scribble’s text contents, etc

Comment by Andrew Heumann on January 28, 2016 at 1:02pm: Hi Martin - the new build with this component is now available from the download link.

Comment by Martin Siegrist on January 28, 2016 at 12:31am: Yes, that's exactly what my friend and I were looking for. Will this be available in the next update of metahopper?

Comment by Andrew Heumann on January 27, 2016 at 10:38pm: made it a little cuter.

Comment by Andrew Heumann on January 27, 2016 at 9:53pm: Hi Martin - something like this?

Comment by Martin Siegrist on January 27, 2016 at 2:07am: It would be great to have a one click possibility in order to enable / disable whatever is inside a group. Your plugin is a great work around but I wish to have this as a standard option in the next GH version. A flip flop button would be even better. Same as the boolean toggle, however one click instead of double click.

Any thoughts?

Comment by Andrew Heumann on January 26, 2016 at 4:00pm: @philip you've given me an idea though - what might work is if I check from each new param both backwards and forewards - if it's mesh going in, and it feeds into another mesh input, chances are it's safe for me to make it a mesh param.

Comment by phillip on January 26, 2016 at 3:54pm: Now I see. Only thought of it "from inside the cluster looking out". Totally clear in that way. Thanks.

Comment by Andrew Heumann on January 26, 2016 at 3:43pm: @phillip - I thought about interpreting the type from the param it comes from. My only frustration with this - mostly in the context of clusters - is that maybe I'm doing some generic operation on geometry, and I'm testing it on meshes - now because the cluster input thinks it only accept meshes, I get an error feeding in surfaces where I wouldn't have if I haven't clustered. With that said, it might be nice to just do it anyway and let the user handle it... especially for those users who live in icon-land instead of text-land :D

Comment by Martin Siegrist on January 26, 2016 at 2:50pm: Thanks, this works now.

Comment by Andrew Heumann on January 26, 2016 at 2:40pm: Good catch Martin - this is now fixed. I've updated this and fixed a couple other bugs in the latest release - available from the link above!
