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.

Comment by Martin Siegrist on June 1, 2016 at 7:43am: I'm not a programmer unfortunately, so I hope someone creates a keyboard activated slider for a future GH version

Comment by Andrew Heumann on June 1, 2016 at 6:57am: (you can edit that script to tell it what keys to listen to. right now it works for F7 and F8)

Comment by Andrew Heumann on June 1, 2016 at 6:56am: At least use events like this:

KeyListener.gh

:D

Comment by Martin Siegrist on June 1, 2016 at 6:47am: hahahahaha

Comment by Andrew Heumann on June 1, 2016 at 6:39am: ahhhh timers are the devil

Comment by Martin Siegrist on June 1, 2016 at 6:35am: Then I did this.

Comment by Andrew Heumann on June 1, 2016 at 6:29am: Never mind got it working. Still don't like it very much :-p

That pop-up winform is a nasty hack...

Comment by Andrew Heumann on June 1, 2016 at 6:27am: eh... I just don't really like that. keyboard and mouse events get nasty real fast. I'd rather not mess with it in MetaHopper. I couldn't even get that GameTools example working. ¯\_(ツ)_/¯

Comment by Martin Siegrist on May 31, 2016 at 6:10am: Sometimes it would be useful to have the option to control a slider through the keyboard. Lets say '-' key moves the value down, '+' key moves the value up. Any idea how to achieve that? Firefly has the 'Is key pressed' component, but it seems a bit complicated...
