Because the data structures are re-used between nodes, a lot of defensive copying is going on in the nodes to make sure cached geometry is not changed.

By using immutable geometry, this can be avoided, and we can multi-thread the code more easily.

1. Create a node, called "alpha"
2. Create a node with the "alpha" node as the prototype.
3. Move the prototype.

If you save the file, "alpha" will be written first, causing the file not to open.

This is only a problem for corevector where we actually use generator / filter as the prototype.

Move focus between panes.

[Cmd + [] & [Cmd + ]]

This functionality is similar to DWM window manager (Linux) or iTerm2 (OS X) for moving between inner-window sections.

Manipulate nodes within the Network Pane.

Arrow Keys (optionally w/ Shift & Alt modifiers to them 10 or .01 grid units)

As mentioned previously, this would mirror both the existing behavior of number sliders in the Parameters/Metadata pane and functionality found within Adobe Creative Suite applications.

Rewind & Play hotkeys.

[Cmd + P] to toggle playing/paused states, [Cmd + R] or [Cmd + Shift + P] to rewind

This would also facilitate a more rapid workflow within NodeBox (when working with animations).

Quickly duplicate nodes with the mouse.

Dragging and Dropping while holding down [Alt]

Another functionality tidbit common to Adobe's Creative Suite. Truly depends on the target audience of the NodeBox software.

In order to select multiple nodes in the network pane, you can drag-select with a mouse. However, this only works when starting the drag in the top left corner of the selection. Starting the drag-selection in anywhere else (for example, clicking and moving the mouse cursor towards the top right) does nothing.

• Nodebox version: 2.0.981
• OSX 10.6.8

The corevector.ndbx file no longer contains references to the handles.

The nodes are fundamentally unfinished. I would leave them out for now, possibly adding them later if the API and implementation are fixed somewhat.

Create a tool that can take a screenshot of the NodeBox window with a certain file.

The icons are all in white, so the network view types should have dark(ish) colors.

The menu item in >Help>Getting Started leads to http://beta.nodebox.net/documentation/getting-started/
And it should lead to http://beta.nodebox.net/documentation/tutorial/getting-started.html

Some way of operating require different ports. For example, there are many ways to sort geometry, with different types of port. (seed is only useful for random sort, while offset is only useful for shift sort).

Design a Parameter object that invokes a function that creates and deletes Ports from a Node object. Drop connections to ports that no longer exist, and maintain existing connections.

Also figure out if we always use the same function, and what happens to ports (are they only hidden temporarily? Are the parameters passed as well?)

Parameters cannot be connected like Ports can.

The wave node exists, but the parameters are a bit weird.

Hello,

I'm following the Data Visualization using Data Stamping tutorial using NodeBox 2.2.1 on Windows XP.

In certain places I cannot use stamp as it returns always the default value.

Steps to reproduce:

1. follow the tutorial
2. at step seven, don't hardcode the 14 value in the Points value of line1 but try using stamp("data_row_count", 1)
3. an error occurs: nodebox.node.ProcessingError: Error occurred while updating parameter <Parameter line1.points (int)>: Parameter points: value 1 is too small. (minimum=2.0)Caused by:
   java.lang.IllegalArgumentException: Parameter points: value 1 is too small. (minimum=2.0)

Looks like stamp connot find a value for "data_row_count" and uses the default value.

Strange things:

• if I deselect Toggle Expression while stamp("data_row_count", 1) is set, the Points value is set to 14. So, in a way, it works.
• it works as expected if I put stamp("data_row_count", 1) as Text value of a textpath node

Tell me if you need additional details.

Cheers,
Giacomo

Steps to reproduce:

1. Create an Ellipse node
2. Click on "Toggle expression" for parameter "width"
3. Enter the expression "stamp("foobar", 50)" and press ENTER
   An ellipse is displayed with height 100 and width 50
4. Click on "Toggle expression" for parameter "width" again.
   Parameter "width" shows 100 again.
   BUT: the ellipse is still displayed with height 100 and width 50.

Repro Steps:

1. Launch NodeBox 2.2.1 on OS X (Lion) 10.7.2
2. Create a "Align" node
   • Create a New Node ([Cmd+Shift+N])
   • Press [Enter]
3. Repeat step 2 until a new node is created on top of an existing node
4. Observer node placement in the Network pane

Actual Results:

A node can be place directly in the same position as a previous node, overlapping & obscuring it.

Expected Results:

New nodes are at least placed away from existing nodes for clarity. And at most, placed adjacent, or near, to recently created nodes to facilitate easier connection using the mouse.

When losing focus (eg minimising, then maximising) the current file appears to be closed (all of the panes are empty).

• Linux 2.6.32-22-generic 36-Ubuntu
• Sun Java(TM) SE Runtime Environment (build 1.6.0_19-b04)
• Nodebox 2.0 snapshot

Repro Steps:

1. Launch NodeBox 2.2.1 on OS X (Lion) 10.7.2
2. Create a "Compound" node
   • Create a new node ([Cmd+Shift+N])
   • Begin typing "Comp"
   • Press [Enter]
3. Create a "Rect" node
   • Create a New Node ([Cmd+Shift+N])
   • Begin typing "Rect"
   • Press [Enter]
4. Click & drag from the output port of the "rect1" to the input port of the "compound1"
5. Observe labels on contextual menu which appears

Actual Results:

The context menu reads:

shape
shapeB

Expected Results:

As with the "Place" node, the labels read:

Shape
Compound

or

Shape A
Shape B

Tried to download files from http://alpha.nodebox.net/download/ (I'm on Windows OS) and for both nodebox-3.0a12-setup.exe or nodebox-3.0a13-setup.exe i get file not found. Not available yet for windows ?

Repro Steps:

1. Launch NodeBox 2.2.1 on OS X (Lion) 10.7.2
2. Create a "Textpath" node
   • Create a New Node ([Cmd+Shift+N])
   • Begin typing "Textp"
   • Press [Enter]
3. Click within the "Text" textField within the Parameters/Metadata pane
4. Press [Tab] 3 times

Actual Results:

The selection traverses over the "Font" and "Center" parameters then disappears, skipping the "Size" parameter after "Font" and "X," "Y," "Width," etc. after "Align."

Expected Results:

The selection lands on draggable selector for the skipped fields before moving to the next, allowing for keyboard input using the up, down, left and right arrow keys. Color field would logically still be skipped. When the selection reaches the last last parameter of the pane, the selection advances to the fist selectable element in the next sequential pane (the most recent node within the "Network" pane, in the default pane arrangement). [Shift+Tab] allows the selection to advance in reverse. This would facility a more rapid workflow within NodeBox.

Tried both the downloadable installer and building from git master branch (as of 2012-06-11). Is the code pane not yet supported, or is this a bug?

Aggregates on one (?) column and sums / averages the other, numeric columns.

• Aggregation methods: sum, avg, ?

Repro Steps:

1. Launch NodeBox 2.2.1 on OS X (Lion) 10.7.2
2. Click the "(>) Play" button below the Source pane
3. Click the "(|<) Rewind" button adjacent
4. Observe the frame count timer to the right

Actual Results:

The frame count timer resets when the "Rewind" button is clicked while animation is playing.

Expected Results:

Animation can be rewound while continuing play to facilite repeated observation of the beginning of an animation. This would also facility a more rapid workflow within NodeBox.

Avira message upon download of nodebox 2.2.1:

'A virus or unwanted program 'ADWARE/Adware.Gen' was found in file 'C:\Users\Susan\AppData...\nodebox-2.2.1-setup.exe'

Repro Steps:

1. Launch NodeBox 2.2.1 on OS X (Lion) 10.7.2
2. Create a "Compound" node
   • Create a New Node ([Cmd+Shift+N])
   • Begin typing "Comp"
   • Press [Enter]

Actual Results:

I am unable to make more than one connection to the input of the Group node.
Attempting to make a second connection merely replaces the existing one.

(I assume Group is the new name for Merge.)

Because "switch" doesn't look at the content of the list, this could fit in the generic list module.

The problem is that if data can only be represented as data (e.g. CSV), the default view is the ugly last resort viewer. In this case, we want to switch to the data panel immediately and disable the viewer option.

But we can look at it differently. If we make the viewer / data into a menu, we can have many options. We can have multiple visualisers for color, for example. If there's only option available, like in the CSV case, we can choose it automatically and disable the menu.

Repro Steps:

1. Launch NodeBox 2.2.1 on OS X (Lion) 10.7.2
2. Create a "Copy" node
   • Create a New Node ([Cmd+Shift+N])
   • Begin typing "cop"
   • Press [Enter]
3. Select the "Order" dropdown menu in Parameters/Metadata pane
4. Begin typing "Sca"

Actual Results:

The cursor on the contextual menu that appears does not seek a menu items matching the typed value (eg. "Scale Rot Trans" or "Scale Trans Rot" in response to the typed "Sca").

Expected Results:

Selecting any item for any node in the Parameters/Metadata pane which is a dropdown menu (the "Copy" node's "Order" parameter or the "Textpath" node's "Font" parameter) allows the user to begin typing to have the nearest matching desired menu item selected. This would facility a more rapid workflow within NodeBox.

If the value of the Copy Stamping Expression is edited directly in the text field, then another node is selected, on selecting the first node again, the new value for the Copy Stamping Expression reverts to the original value before editing. Allow direct editing in the text field? (OS X 10.5.8).

Not a major bug but annoying. [3.0a22 - Windows 7]

(You can still access "New Node" interface by double clicking network background or clicking "New Node" button.)

PS
If these minor annoyance type bugs aren't a concern right now I can just keep them to myself if you like.

Repro Steps:

1. Launch NodeBox 2.2.1 on OS X (Lion) 10.7.2
2. Close the new document by
   • Press [Cmd + W]
   • Selecting File > Close
   • Clicking red (x) button
3. Press [Cmd + N] to create a new document

Actual Results:

[Cmd + N] does not have functionality. However, selecting File > New works.

Expected Results:

Hotkeys/keyboard shortcuts listed in the applications UI function as stated.

Closing & re-opening the application solves this issue.

OS X: 10.7.2
Nodebox version: 2.2.1
Java: 1.6.0_29-b11-402-11M3527

Repro Steps:

1. Launch NodeBox 2.2.1 on OS X (Lion) 10.7.2
2. Create a "Align" node
   • Create a New Node ([Cmd+Shift+N])
   • Press [Enter]
3. Press various arrow keys with the new node selected in the Network pane

Actual Results:

Selected nodes cannot be moved.

Expected Results:

Arrow keys can be used to reposition nodes within the Network pane; a single arrow key press-release moving the selected node 1 point on the pane's grid. Optionally (as with the draggable numbers within the Parameters/Metadata pane discussed here: http://beta.nodebox.net/documentation/using/gui.html) Shift and Alt modifiers to the arrows keys could be used to reposition nodes 10 or .01 positions on the pane's grid. This behavior is common to Adobe creative suite apps such as Photoshop and Illustrator and is functionality professional designers/Adobe product users will appreciate. This would also facility a more rapid workflow within NodeBox.

OS X: 10.7.2

To reproduce:

1. create a "Code" node
2. modify its Python code in the source pane
3. pressing Ctrl+Z does not undo the latest code modifications but the insertion of the "Code" node instead => the Code node vanishes, the code and all its changes are lost

Please extend undo to code modifications, too

Hi, the nodebox app looks interesting, would be nice to have more screenshots on the project's site.

Thanks!

Repro Steps:

1. Launch NodeBox 2.2.1 on OS X (Lion) 10.7.2
2. Hover the mouse over the menu bar > Window > Layout

Actual Results:

No further menus or options appear despite indicative ">" icon on the "Layout" option.

Expected Results:

Several options of alternative (to the default) window pane arrangement(s) appear.

OS X: 10.7.2

Repro Steps:

1. Launch NodeBox 2.2.1 on OS X (Lion) 10.7.2
2. Observe the "(+) New Node" button's "spotlight"

Actual Results:

Even after achieving a familiarity with the NodeBox program, the spotlight continues to appear when creating a new document or opening the application. This functionality appears indicative of an inexperienced user.

Expected Results:

The new node "spotlight" only appears:

• The first several times the application is opened.
• If a newly created document is the first one opened.
• The application has not been used for over a month.

This is a low severity issue as the spotlight is easily dismissed by clicking anywhere within the application.

Hi,

I'm evaluating NodeBox for data visualisation. Using NodeBox 3.0a14 and foliowing this tutorial on the alpha site. I can't find a Datastamp node in the list of available nodes.

Is this an issue of out-of-date documentation, or a missing node?

Thanks.

The list of nodes has increased a lot and the current panel is unworkable. Design a new system for easily creating new nodes, preferably in categories.

IMO we need a more informal/friendly place to throw ideas around and ask questions.

Something like this...

Convert automatically between types.

When you connect a floating-point number to something that takes in an integer (like an "amount" port), you get an error.

NB should automatically convert the float to an int, rounding the number off in the process.

Conversion should work just like a node. They take in lists, and return lists of equal, or different size.

For example, a Geometry object can be converted to something that takes points. The converter node will take in a list of Geometry objects and return a list of Points, ready to be consumed by a node that takes Points.
