Can I ask you to start a new topic for this? It’s going to be hard to find specific bug reports and discussions in this post later.

It’s not yet possible to display the user-assigned name of components. I haven’t found a solution yet to this problem I like. I want to avoid vertical text as that’s much harder to read, so the GH1 approach doesn’t work. Whether the icon automatically disappears when you assign a custom name, or whether that remains an option is yet to be seen.
So they’re easier to hit? So many UI decisions have been made in the spur of the moment and are liable to change still. Those pop-up forms were much smaller a few months ago so having huge elements on them wasn’t an issue. Those days are gone now and it’s only going to get worse, so those bug buttons will probably be shrunk sometime soon.
It’s a cat. Cat’s are exceedingly random, which is why I picked that.

I wrote an entire icon display pipeline from scratch because nothing out there did what I really needed. One of the features of this code is that it understands special colours and resolves them only at draw-time. Although you cannot do this yet, it is in principle possible to assign different colours to those special colour codes, so if you don’t like the orange or the blue, that can be changed at runtime without having to reload, let alone redesign the icons themselves.
Replacing the hard-coded colour fallbacks for the Cyan and Yellow to Grape and Lime results in this:
… or just grey:

The cat we had when I was child was very predictable, especially when treats came into play. 
Epic! Love the toned down grey “theme”.
So for meta-data, name:value = key:value = immutable:mutable?
If so, then every new key created would have to be a new type?
Does that mean user-generated keys in Rhino can put used as inputs to GH2, but once inside GH2 the key itself cannot be renamed, but the values can be changed?
Slightly more general question: GH2 is written in C#, an imperative/object-oriented paradigm, but the actual GH2 (and all node-based programming?) scripts are replicating a functional paradigm, so is your approach to make the components act like pure functions as much as possible? (I’m not a programmer, so maybe I’m completely misunderstanding this.)
On macOS, there seems to be a bug, where sporadically the components from the Vector, Curve, and Surface tabs/categories don’t all load.
Hi do you know where does custom preview component in grasshopper2?and how does we displaying render brep mesh curve,… by material and color?
Yes, in the Data tab/category under Meta look for the Assign Display Color component. I don’t know if assigning a material is possible yet, but there’s also a Assign Display Diffuse component, which lets you set the diffuse material colour.

Hi David & team, Congrats on this awesome milestone and thanks for your clarity on communications and expectations for all of us.
I’ll start playing with this soon, one thing I was hoping for and I’d like to know: how much is part of your GH2 architecture, is a fluid segmentation/separation of:
- input geometry (if any)
- GH UX canvas (PC/client device/website)
- computing environment (your PC/other PCs/AWS instances)
- Output (pre/post baking to any/multiple places -your PC/client device/website, other software such us Blender, Unreal, Revit…)
I know your team has been working on all the foundation and pluming for all those things to happen. It would be great to now see you all building a welcoming home for all this where we can enjoy doing our work in).
Best,
Gustavo
Oh I’m here for the bugs. Is there a topic for debugging yet?
Do you prefer a topic per bug or one called GH2 bugs?
A topic per bug is much better than a single topic for many bugs.
Very nice.
Since gh files can’t open in Grasshopper 2 i think people will continue use Grasshopper 1.
Will Grasshopper 2 replace Grasshopper 1 or it will be available as second option?
@DavidRutten congrats on the first release of GH2, I can’t wait to get my head into the new possiblities.
Not quite as excited about rewriting my 6800 component def of KaroroCAD from scratch to work in GH2, but I’m sure there will be a lot I can refactor in the process.
Cheers

There is no replacement going on. We will continue to support and add new features to Grasshopper 1. You should also be able to run both Grasshopper 1 and Grasshopper 2 at the same time. You have to remember that this is the first alpha of GH2 and we expect it to take quite a while before we hit a point where we would consider it a stable official release.

When this happens, can you run the G2PluginViewer and see if you can find any error messages there, or whether the components missing in the tabs are in fact available in that viewer?
Very nice to see that ins’t an April fool
What is meant by ‘immutable’ in this case is that once a blob of meta data has been created, it cannot be changed. Not structurally (i.e. remove or add values to it), nor change any of the contained values. So if you add a new named value to an existing meta data blob, what you get a new blob containing all the old values plus that new value.
That bit is usually obscured in the UI, but it does mean that all the values inside the data must also be of only immutable types. So it’s not possible to store a Rhino curve or brep in meta-data, as those objects can be changed. To get around that limitation it is possible to store text and byte-arrays in meta-data, so a curve could be serialised to JSON or XML or an OpenNURBS chunk and included. It would then have to be deserialised when you want to get it out, which introduces overhead that wouldn’t exist if the meta data had been mutable.
On the other hand, a single meta datum can be shared amongst thousands of values, which again reduces memory overhead.

I haven’t done any work yet on rendering and materials. There’s no custom display component yet either, but as @diff-arch pointed out you can assign meta data to values which may affect their display colour, point symbol, dash pattern and so on. Also note that all previewable components and parameters have some very basic preview colour overrides in their pop-up options.

Yeah you’re better off waiting a few months before you even start to consider converting production files.
There are a lot of file-management features planned for GH2 which aren’t done yet.
