2.2.0

PluginBlueprint 2.2.0 lets you group nodes into subgraphs and adds a constant for single characters.

New

• Subgraphs. Select some nodes and choose Convert to subgraph from a node's menu, or add graph → Subgraph from search. A subgraph keeps its nodes on their own canvas: double-click it to open it, and use ‹ Back to return. Subgraph Input and Subgraph Output nodes inside become the pins on the outside, and subgraphs can contain other subgraphs. Your plugin works exactly the same as before you grouped the nodes. Problems, Find, undo and build errors all reach nodes inside subgraphs. See Subgraphs.
• Char constant. Double-click a char input, such as the & in ChatColor.translateAlternateColorCodes, to create a Char constant and type the character. Before, a char input needed a Number constant set to the character's code.

Changed

• Importing a snippet now shows the Java code warning for Java code nodes inside subgraphs too.

Projects saved with 2.0 and 2.1 open and build the same as before. Once a project uses subgraphs, open it with 2.2.0 or newer: 2.1.0 warns that it was saved by a newer version, and saving it there would remove the subgraphs' contents.

PluginBlueprint is free and open source. If it helps you, you can pay what you want.
