Bobbin VS Code Extension v0.3.0

Full Changelog: vscode-v0.3.0...vscode-v0.3.0

What's New

Commands System

Dialogue scripts can now trigger game effects through commands — fire-and-forget function calls from dialogue to your game:

extern give_item(name, count)
extern play_sound(name)

You found a treasure chest!
give_item("gold_coin", 50)
play_sound("chest_open")
Take these coins as a reward.

Commands are declared with extern (like host variables) but include parameters. The runtime validates arity at compile time — calling give_item("sword") when it expects 2 arguments produces a clear error.

GDScript Integration

Pass command handlers to Bobbin.create():

var runtime = Bobbin.create(
    "res://dialogue/quest.bobbin",
    {},  # saved_variables
    {"player_name": "Hero", "gold": 100},  # host_state
    {    # commands
        "give_item": func(args): inventory.add(args[0], int(args[1])),
        "play_sound": func(args): AudioManager.play(args[0]),
    }
)

Live Host State

Changes to the host_state dictionary are now immediately visible to the runtime. When a command handler updates host state, subsequent dialogue lines see the new values without explicit sync:

func _on_give_gold(args):
    var amount = int(args[0])
    _host_state["gold"] += amount  # Runtime sees this immediately

give_gold(100)
You now have {gold} gold.  # Shows updated value

Other Changes

• Syntax highlighting for command invocations in Godot editor
• Improved error messages for command-related issues
• Fixed WASM build compatibility with recent Rust toolchain changes

Upgrade Notes

This release is backwards compatible. Existing scripts without commands continue to work unchanged.

Bobbin VS Code Extension v0.2.0

Full Changelog: vscode-v0.1.0...vscode-v0.2.0

New Features

Conditional Syntax Support

Full syntax highlighting and language server support for if/elseif/else blocks:

if gold >= 100
    You can afford the premium item!
elseif gold >= 50
    You can afford the standard item.
else
    You need more gold.

Expression Support Everywhere

• Arithmetic operators: +, -, *, /, %
• Comparison operators: ==, !=, <, <=, >, >=
• Logical operators: and, or, not
• Parentheses for grouping: (a + b) * c

Use expressions in variable assignments:

set total = price * quantity
temp discount = base_price - (base_price * 0.1)

And in string interpolations:

You have {gold} gold. That item costs {price * quantity} gold.
Your balance after purchase: {gold - price}

Enhanced Syntax Highlighting

• Conditional keywords (if, elseif, else)
• Logical operators (and, or, not)
• Comparison and arithmetic operators
• Improved expression highlighting inside {...} interpolations

Improved Diagnostics

The language server now provides better error messages for:

• Invalid expressions
• Type mismatches in conditions
• Malformed conditional blocks

Bug Fixes

• Fixed scanner issue with choices inside if blocks that have else clauses

Bobbin Godot Addon v0.1.0

🎉 Initial Release — A narrative scripting language for branching dialogue and interactive stories in Godot 4.3+

Highlights

Bobbin brings a clean, writer-friendly syntax for creating interactive dialogue in your Godot games. This first release includes a complete runtime, Godot integration, and cross-platform support.

Features

Language

• Dialogue scripting — Simple, indentation-based syntax for writing branching narratives
• Choice sets — Support for player choices with nested branching paths
• Variable system — Three variable scopes:
  • temp — Session-scoped variables (cleared on restart)
  • save — Persistent variables (survive save/load)
  • extern — Read-only variables provided by the host game
• String interpolation — Embed variables in dialogue with {variable_name} syntax
• Assignment statements — Modify variables with the set keyword

Godot Integration

• GDExtension-based — Native performance via Rust and gdext
• ScriptLanguageExtension — Full editor support for .bobbin files
• Simple API — from_string(), advance(), select_choice(), and more
• Custom script icon — Bobbin files are easily identifiable in the editor

Developer Experience

• Rich error messages — Rust-quality diagnostics with source spans and context
• Cross-platform builds — Windows, Linux, macOS, and Web (WASM)
• Comprehensive test suite — Runtime tests and Godot smoke tests
