Anchor Phase 10 Part 1

Summary

Started Phase 10 implementation. Spent significant time on YueScript setup before realizing the planned submodule architecture was too complicated, leading to a project structure overhaul.

Initial YueScript Setup (10.1):

Symlink and Path Confusion:

Naming Discussion:

Architecture Reconsideration:

Project Structure Overhaul:

Framework Implementation:

Testing:

Documentation:


Hello, Claude. Let's get started on Phase 10 today, I believe the document can be found in reference/. This session is a mix between "Engine Mode" and "Game Mode", since we're building out the YueScript part of the game, along with default engine objects and so on. Due to this, I'll want to review every single line of code you write, this means you shouldn't go too fast and write too many things at once without giving me a chance to review. You should also use the AskUserQuestion tool to ask questions liberally throughout the session. Anything that you have doubts about, or that includes tradeoffs, that could be done in multiple ways, etc, just ask. I am very particular about the YueScript code you'll be writing, unlike the C code where I let your other instances own it more freely.

Does this make sense?

Yes, that makes complete sense. You want:

  1. Slow, incremental progress — complete small pieces, pause for your review
  2. Liberal use of AskUserQuestion — for doubts, tradeoffs, design choices
  3. You own the YueScript code — I propose, you approve (unlike C code where I had more autonomy)

Let me read the Phase 10 implementation plan first.

1→# Phase 10: YueScript Object System - Detailed Implementation Plan
     2→
     3→## Overview
     4→
     5→Phase 10 transforms Anchor from a C engine with Lua bindings into a full game framework. The core deliverable is the object tree system with operators, plus built-in objects (Timer, Spring, Collider, etc.) that wrap C resources.
     6→
     7→---
     8→
     9→## 10.1 YueScript Build Integration
    10→
    11→**Goal:** `.yue` files compile to `.lua` with accurate line number reporting for debugging.
    12→
    13→**Steps:**
    14→1. Install YueScript compiler (via LuaRocks or standalone)
    15→2. Create `compile-yue.bat` script that runs `yue -r` on framework and game folders
    16→3. Test that syntax errors report correct `.yue` line numbers
    17→
    18→### Repository Structure
    19→
    20→Each game is its own repository with Anchor as a submodule:
    21→
    22→```
    23→emoji-ball-battles/              # Game repo (self-contained)
    24→├── anchor/                      # Git submodule → Anchor repo

    30→│   │   │   └── ...
... [415 more lines]

I've read the Phase 10 implementation plan. It covers:

  1. 10.1 — YueScript build integration
  2. 10.2 — Update loop (C calls Lua phases)
  3. 10.3 — Base object class with tree operations
  4. 10.4 — Operators (^, /, +, >>)
  5. 10.5 — Operator inheritance via __inherited
  6. 10.6 — Action system (early/main/late)
  7. 10.7 — Phase helpers (U, L, X)
  8. 10.8 — Built-in objects (Timer, Spring, Collider)

The suggested implementation order (10.9) starts with YueScript compilation and builds up incrementally.

There's also an open question about the root object — whether to replicate the old an "God object" pattern or do something different.

AskUserQuestion

User has answered your questions: "Where would you like to start? The document suggests starting with YueScript compilation (10.1), but you may have already set some of this up or want to start elsewhere."="10.1 YueScript compilation". You can now continue with the user's answers in mind.

Starting with 10.1 YueScript compilation. Let me check what currently exists in the engine/yue/ directory.

Glob (engine/yue/*/)

E:\a327ex\Anchor\engine\yue\README.md

Read (E:\a327ex\Anchor\engine\yue\README.md)

1→# YueScript Framework
     2→
     3→This folder contains the YueScript framework classes (object, timer, spring, collider, etc.).
     4→
     5→These files are compiled to Lua and used by games via:
     6→```yuescript
     7→object = require 'yue.object'
     8→timer = require 'yue.timer'
     9→```
    10→
    11→See `reference/phase-10-implementation-plan.md` for implementation details.
    12→

The engine/yue/ folder is currently empty except for a placeholder README.

For 10.1, the plan mentions:

  1. Install YueScript compiler (via LuaRocks or standalone)
  2. Create compile-yue.bat script
  3. Test that syntax errors report correct .yue line numbers

AskUserQuestion

User has answered your questions: "Do you already have YueScript installed, or should we start with installation?"="Start with installation, I want the YueScript executable to live in our folders itself, not implicit somewhere else. The final build that collapses the engine + game executable should also add it.", "Where should the compile script live and what should it be called?"="Where the engine scripts are, wherever they are.". You can now continue with the user's answers in mind.

Got it — you want the YueScript executable bundled within the project, not a system-wide install. Let me check the current script locations and build structure.

Glob (scripts/*)

E:\a327ex\Anchor\scripts\jsonl-to-markdown.py
E:\a327ex\Anchor\scripts\patch-claude-code.sh
E:\a327ex\Anchor\scripts\build.bat
E:\a327ex\Anchor\scripts\monitor_sim.c
E:\a327ex\Anchor\scripts\new-game.sh

Glob (engine/build/*/)

E:\a327ex\Anchor\engine\build\anchor.exe

Engine scripts are in engine/ (like build.bat), and binaries go in engine/build/.

For bundling YueScript with the project, I have a few questions:

AskUserQuestion

User has answered your questions: "Where should the YueScript executable live within the project?"="Do we already have any other executables like this in the project somewhere?", "How should we obtain the YueScript executable? YueScript can be distributed as a standalone exe or built from source."="Download release binary". You can now continue with the user's answers in mind.

Good question — let me check what executables already exist in the project.

Glob (*/.exe)

E:\a327ex\Anchor\reference\love-compare\tools\lua54.exe
E:\a327ex\Anchor\reference\love-compare\tools\yue.exe
E:\a327ex\Anchor\reference\super emoji box\tools\lua54.exe
E:\a327ex\Anchor\reference\super emoji box\tools\yue.exe
E:\a327ex\Anchor\reference\super emoji box\tools\love.exe
E:\a327ex\Anchor\reference\super emoji box\tools\lovec.exe
E:\a327ex\Anchor\reference\love-compare\tools\love.exe
E:\a327ex\Anchor\reference\love-compare\tools\lovec.exe
E:\a327ex\Anchor\engine\build\anchor.exe

There's already a precedent. The reference projects have a tools/ folder:

So the pattern is <project>/tools/. For the engine itself, this would suggest engine/tools/yue.exe.

Also — there's already a yue.exe in those reference folders. We could copy that one directly.

AskUserQuestion

User has answered your questions: "Should we copy yue.exe from the reference folder to engine/tools/, or download a fresh copy from GitHub releases?"="Sure, use engine/tools as the place for the executable, but get the latest from GitHub". You can now continue with the user's answers in mind.

I'll download the latest YueScript from GitHub. Let me find the releases page.

WebSearch (YueScript GitHub releases Windows download)

WebFetch (https://github.com/IppClub/YueScript/releases)

Based on the webpage content provided, I cannot find specific download URLs for Windows executables (yue.exe or similar builds).

The page shows the releases list for IppClub/YueScript with version numbers like v0.30.4, v0.30.3, and earlier versions, but the actual asset download links are not visible in the HTML content provided. The page indicates "Assets 10" for most releases, but states "Loading" and "Uh oh! There was an error while loading. Please reload this page."

To find Windows executable downloads, you would need to:

1. Visit the actual GitHub releases page directly
2. Click on a specific release tag (e.g., v0.30.4)
3. Scroll to the Assets section where download links appear

I cannot provide exact URLs without access to the fully loaded asset information on the page.

The releases page has dynamic loading. Let me try the GitHub API to get the exact asset URLs.

Yuescript version: 0.30.4

YueScript v0.30.4 is installed at engine/tools/yue.exe.

Now for the compile script. Looking at the Phase 10 plan, the directory structure for a game is:

game-repo/
├── anchor/                    # submodule
│   └── engine/
│       ├── yue/              # framework .yue files
│       └── tools/yue.exe
├── yue/                       # junction → anchor/engine/yue
├── main.yue                   # game code

The compile script needs to handle both:

  1. Framework filesanchor/engine/yue/*.yue
  2. Game files*.yue in the game root

AskUserQuestion

User has answered your questions: "Where should compile-yue.bat live? If in engine/, it would be called from the game directory as `anchor/engine/compile-yue.bat`. Or it could live in the game repo created by new-game.sh."="Don't we have to call anchor.exe game-repo to run the game?", "Should the script compile in-place (output .lua next to .yue) or to a separate build folder?"="I believe the documentation details this, you should read in more detail.". You can now continue with the user's answers in mind.

Good points — let me re-read the relevant sections more carefully and check how anchor.exe is invoked.

This is clearer now. From the file-organization-walkthrough:

  1. Compilation is in-place: yue -r produces .lua alongside .yue
  2. Run from game directory: ../../engine/build/anchor.exe .
  3. Framework access: Symlink/junction yue/engine/yue/

For the Phase 10 submodule structure: game-repo/ ├── anchor/ # submodule │ └── engine/ │ ├── yue/ # framework .yue files │ ├── tools/yue.exe │ └── build/anchor.exe ├── yue/ # junction → anchor/engine/yue ├── main.yue

The compile script would need to:

  1. Compile framework: anchor/engine/yue/*.yue
  2. Compile game: ./*.yue
  3. Use: anchor/engine/tools/yue.exe

AskUserQuestion

User has answered your questions: "For the compile script: should it live in engine/ (games call anchor/engine/compile-yue.bat) or be part of new-game.sh template (each game has its own copy)?"="In engine/ (Recommended)". You can now continue with the user's answers in mind.

I'll draft the compile script. It would be run from the game directory, so paths are relative to there:

@echo off
REM compile-yue.bat - Compiles YueScript files to Lua
REM Run from game directory: anchor\engine\compile-yue.bat

setlocal

REM Get the directory where this script lives
set SCRIPT_DIR=%~dp0

REM yue.exe is in tools/ relative to this script
set YUE=%SCRIPT_DIR%tools\yue.exe

REM Compile framework (engine/yue/)
echo Compiling framework...
"%YUE%" -r "%SCRIPT_DIR%yue"

REM Compile game (current directory)
echo Compiling game...
"%YUE%" -r .

echo Done.

What this does:

  1. Locates yue.exe relative to the script location (engine/tools/yue.exe)
  2. Compiles framework files (engine/yue/*.yueengine/yue/*.lua)
  3. Compiles game files (./*.yue./*.lua)
  4. Uses -r flag to preserve line numbers for error messages

User has answered your questions: "Does this script structure look right? Any changes before I write it?"="Looks good, write it". You can now continue with the user's answers in mind.

Write (E:\a327ex\Anchor\engine\compile-yue.bat)

File created successfully at: E:\a327ex\Anchor\engine\compile-yue.bat

Created engine/compile-yue.bat.

Now for step 3: Test that syntax errors report correct .yue line numbers. We need a test file to verify this works.

AskUserQuestion

User has answered your questions: "Should I create a simple test.yue file in engine/yue/ so you can test the compilation and line number reporting?"="Yes, create test file". You can now continue with the user's answers in mind.

Write (E:\a327ex\Anchor\engine\yue\test.yue)

File created successfully at: E:\a327ex\Anchor\engine\yue\test.yue

Created engine/yue/test.yue.

To test, run from the Anchor root (or any game directory): bash engine/compile-yue.bat

This should create engine/yue/test.lua. To test line number reporting, you can add a deliberate syntax error to test.yue (like a missing end or typo) and see if the error message points to the correct .yue line.

Let me know how the test goes, or if you want to proceed to the next step (10.2 Update Loop or 10.3 Base Object).

Create main.yue in emoji-ball-battles and let's run all our tests from there. Create the code necessary to write it, and then run it yourself.

Let me check the current state of emoji-ball-battles and set it up properly.

The directory doesn't exist. Let me create it with the proper structure:

The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). To tell you how to proceed, the user said:
the test.yue file in engine/yue is acting like a module that the main.yue file will load. So you should require it here, and use its code to test if it all works. You should also compile the yue code on both Anchor and the game repository, and then run it all together.

Got it. main.yue should require yue.test and use it. Let me write that properly:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

main.lua compiled successfully. The errors are from old example files in the submodule (not our code).

But there's a problem: the yue symlink in emoji-ball-battles points to the submodule, which doesn't have test.lua. Let me check and fix this:

Bash (ls -la E:/a327ex/emoji-ball-battles/yue/)

The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). STOP what you are doing and wait for the user to tell you how to proceed.

Why are .yue files in the reference/ folder compiling? Those have nothing to do with anything.

You're right. The -r flag recursively compiles everything, including the anchor/ submodule which has old example files in reference/.

The compile script should only compile:

  1. Framework: engine/yue/*.yue
  2. Game: ./*.yue in the game root (and maybe game subdirectories, but NOT the anchor/ submodule)

AskUserQuestion

User has answered your questions: "How should the game compilation work? The issue is -r recurses into anchor/ submodule."="Compile only the code necessary for the engine to work and games to work.". You can now continue with the user's answers in mind.

Wait, I need to re-check. Looking at yue's help output earlier:

-r       Rewrite output to match original line numbers

The -r flag is for line number rewriting, not recursion. The recursion happens automatically when you pass a directory. So when I passed E:/a327ex/emoji-ball-battles, it recursed into everything including anchor/.

For the game, I should compile only the game's .yue files directly, not the whole directory. Let me compile correctly:

Bash (E:/a327ex/Anchor/engine/tools/yue.exe -r E:/a327ex/emoji-ball-battles/main.yue)

Rewritten built E:/a327ex/emoji-ball-battles/main.lua

Now let me check if the yue symlink can find test.lua:

Bash (ls -la E:/a327ex/emoji-ball-battles/yue/)

The symlink points to the submodule, which doesn't have test.lua. I need to update it to point to the main Anchor repo for development:

Bash (cd E:/a327ex/emoji-ball-battles && rm yue && ln -s E:/a327ex/Anchor/engine/yue y...)

The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). To tell you how to proceed, the user said:
please explain what you're doing here more carefully.

Let me explain the situation:

Current state:

The problem: The yue symlink in emoji-ball-battles points to the submodule's engine/yue/, not the main Anchor repo. So when main.lua does require 'yue.test', Lua follows the symlink to the submodule, which doesn't have test.lua.

Options:

  1. Update symlink — Point yue to E:/a327ex/Anchor/engine/yue (main repo) for development
  2. Compile in submodule — Copy test.yue to submodule and compile there
  3. Commit + update submodule — Commit our changes to Anchor, push, update submodule

For local development, option 1 is simplest — the symlink points to where we're actively working. Does that make sense, and which approach do you prefer?

Wasn't 1 already the case? Wasn't it pointing to the engine/yue folder already? You're saying both that the problem is that it point's to engine/yue, and that option 1 would have it point to engine/yue. I don't understand.

You're right, I was unclear. Let me be precise:

There are two separate copies of the Anchor repo:

  1. Main repo: E:/a327ex/Anchor/ — where we're developing right now
  2. Submodule: E:/a327ex/emoji-ball-battles/anchor/ — a git submodule (separate copy, pinned to an older commit)

The symlink currently points to: E:/a327ex/emoji-ball-battles/anchor/engine/yue/ (the submodule)

But I compiled test.yue in: E:/a327ex/Anchor/engine/yue/ (the main repo)

These are two different directories on disk. The submodule is its own full copy of Anchor, just at an older commit that doesn't have our new files.

Option 1 would change the symlink to point to the main repo (E:/a327ex/Anchor/engine/yue/) instead of the submodule (E:/a327ex/emoji-ball-battles/anchor/engine/yue/).

Wasn't that already what was done? It makes no sense to symlink to the folder in emoji-ball-battles.

You're right, it doesn't make sense. But that's what the symlink currently shows:

yue -> /e/a327ex/emoji-ball-battles/anchor/engine/yue/

This was probably created incorrectly during initial setup. It should point to the main Anchor repo, not to itself via the submodule.

Should I fix it to point to E:/a327ex/Anchor/engine/yue/?

Sure, but how will the .lua file be seen from the emoji-ball-battles folder?

When Lua does require 'yue.test', it looks for ./yue/test.lua relative to the current directory.

If the symlink points to E:/a327ex/Anchor/engine/yue/: E:/a327ex/emoji-ball-battles/yue/ → E:/a327ex/Anchor/engine/yue/

Then from Lua's perspective: ./yue/test.lua → E:/a327ex/Anchor/engine/yue/test.lua

The symlink makes the files "appear" to be at ./yue/ even though they're physically in the Anchor repo. That's how symlinks work — they're transparent to programs reading files.

Is test.lua in engine/yue/ in the Anchor repo?

Yes, test.lua is there. So once I fix the symlink, it should work. Let me fix it:

Bash (cd E:/a327ex/emoji-ball-battles && rm yue && ln -s E:/a327ex/Anchor/engine/yue y...)

Now I can see test.lua through the symlink. Let me run the game:

Bash (cd E:/a327ex/emoji-ball-battles && E:/a327ex/Anchor/engine/build/anchor.exe .)

The YueScript compilation pipeline is working:

  1. test.yue compiled to test.lua in engine/yue/
  2. main.yue compiled to main.lua in the game folder
  3. The symlink lets require 'yue.test' find the framework module
  4. anchor.exe runs successfully

10.1 YueScript Build Integration is complete. Ready for the next step?

There's nothing that needs to be changed in documentations to reflect anything we did here, right? Everything is working as one would expect normally.

Correct. Everything matches what the Phase 10 plan and file-organization-walkthrough already describe:

The only implementation detail not explicitly documented is engine/tools/ as the location for yue.exe, but that follows the pattern from the reference projects. No doc updates needed.

What's the next step?

According to section 10.9, the implementation order is:

  1. YueScript compilation
  2. Update loop — C calls Lua phases, basic frame execution
  3. Base object + tree operations
  4. Named linking
  5. Tagging
  6. Operators
  7. Action system
  8. Phase helpers
  9. Horizontal links
  10. Named child replacement
  11. Built-in objects

Next is 10.2 Update Loop — modifying anchor.c to call Lua functions each frame (engine_collect_objects, engine_run_early, engine_run_main, engine_run_late, engine_cleanup).

This is where we define the execution model that everything else plugs into. Want to proceed with that?

Let's change this. We want anchor.c to only call one Lua update function, and then everything we do inside that is YueScript's/Lua's responsibility. We don't need for it to call multiple update functions since nothing happens on the C side between those functions, right?

You're right. If nothing happens on the C side between those calls, there's no reason to split them up. The C side just needs to call one function like engine_update(dt), and YueScript handles all the phases internally.

This simplifies the architecture:

C side: c // Just one call per frame lua_getglobal(L, "engine_update"); lua_pushnumber(L, dt); lua_call(L, 1, 0);

YueScript side orchestrates everything: yuescript engine_update = (dt) -> collect_objects! run_early dt run_main dt run_late dt cleanup!

Does the C side already call a Lua update function, or do we need to add that?

You should check it, I don't know.

Grep (lua_getglobal.update|lua_call.update)

6577-        if (!error_state) {
6578-            lua_pushcfunction(L, traceback);
6579-            int err_handler = lua_gettop(L);
6580:            lua_getglobal(L, "update");
6581-            if (lua_isfunction(L, -1)) {
6582-                lua_pushnumber(L, PHYSICS_RATE);
6583-                if (lua_pcall(L, 1, 0, err_handler) != LUA_OK) {

The C side already calls a global update function with dt. Let me see more context:

Grep (lua_getglobal)

6578-            lua_pushcfunction(L, traceback);
6579-            int err_handler = lua_gettop(L);
6580:            lua_getglobal(L, "update");
6581-            if (lua_isfunction(L, -1)) {
6582-                lua_pushnumber(L, PHYSICS_RATE);

Grep (lua_getglobal(L,)

6580:            lua_getglobal(L, "update");

The C side already does exactly what we want — it only calls one function:

lua_getglobal(L, "update");
lua_pushnumber(L, PHYSICS_RATE);
lua_pcall(L, 1, 0, err_handler);

So we don't need to modify anchor.c at all. We just need to define a global update function in YueScript that orchestrates all the phases internally.

Ready to write the YueScript update loop?

Yes, how will you write it exactly?

Here's my thinking:

The update loop depends on the object system (which we haven't built yet), so I see two approaches:

Option A: Skeleton now, fill in later yuescript -- engine.yue update = (dt) -> -- TODO: collect objects -- TODO: run early phase -- TODO: run main phase -- TODO: run late phase -- TODO: cleanup

Option B: Full implementation assuming object system exists ```yuescript -- engine.yue _collected = {}

update = (dt) -> collect! run_early dt run_main dt run_late dt cleanup!

collect = -> _collected = {} collect_recursive root

collect_recursive = (obj) -> return if obj.dead table.insert _collected, obj for child in *obj.children collect_recursive child

run_early = (dt) -> for obj in *_collected continue if obj.dead obj\early_update dt if obj.early_update -- run early actions...

-- etc. ```

This raises questions:

  1. Where does root come from? The global root object that holds the tree.
  2. Should this be in a separate file like engine.yue that main.yue requires?
  3. Or inline in main.yue for simplicity during development?

How do you want to structure this?

  1. Create a default object class in object.yue, this should contain the most basic object attributes, or none for now. Then we create a global root object called "an" for now. I don't know yet if we'll go with this in the end, but for now it will do.
  2. This should be in an init.yue file, so that the gameplay code (main.lua) just requires "yue" and it automatically initializes the engine. Then, in this init file, we require every engine yue file, like object.yue and any others.

Additionally, do not the DFS search recursively for collecting objects, change to a flat version with for loops, I find it easier to reason about it that way. Do the full implementation with the object structure we have now from object.yue and make it actually work.

Here's my proposed structure:

object.yue — just the class definition: ```yuescript class object new: (name) => @name = name @parent = nil @children = {} @dead = false

object ```

init.yue — requires everything, creates root, defines update: ```yuescript object = require 'yue.object'

-- Global root object export an = object 'an'

_collected = {}

collect = -> collected = {} stack = {an} while #stack > 0 obj = table.remove stack if not obj.dead table.insert collected, obj for i = #obj.children, 1, -1 table.insert stack, obj.children[i]

run_early = (dt) -> for obj in *_collected continue if obj.dead obj\early_update dt if obj.early_update -- actions later...

run_main = (dt) -> for obj in *_collected continue if obj.dead obj\update dt if obj.update

run_late = (dt) -> for obj in *_collected continue if obj.dead obj\late_update dt if obj.late_update

cleanup = -> stack = {an} while #stack > 0 obj = table.remove stack i = 1 while i <= #obj.children child = obj.children[i] if child.dead child\destroy! if child.destroy obj[child.name] = nil if child.name table.remove obj.children, i else table.insert stack, child i += 1

export update = (dt) -> collect! run_early dt run_main dt run_late dt cleanup!

{:object, :an} ```

main.yue (game) would do: yuescript {:object, :an} = require 'yue' -- game code...

Questions before I write:

  1. The iterative DFS adds children in reverse order (#obj.children, 1, -1) to maintain left-to-right traversal. Is that the order you want, or does order not matter?

  2. Should I include the action system now (early_actions, actions, late_actions), or leave it as a skeleton to add later?

Make everything on the engine side global by default.

  1. Yes, it should be left to right.
  2. No, leave it for later.

Updated plan with globals:

object.yue: ```yuescript class object new: (name) => @name = name @parent = nil @children = {} @dead = false

export object ```

init.yue: ```yuescript require 'yue.object'

export an = object 'an'

main.yue (game): yuescript require 'yue' -- object, an, update are all global now

Does this look right? If so I'll write the files.

Yes. Can we rename "yue" to be "anchor", so that gameplay code calls require 'anchor', or would that mess with the symlink?

There's a conflict. Currently in a game repo:

game/
├── anchor/          # Git submodule (the whole Anchor repo)
├── yue/             # Symlink → anchor/engine/yue/

If we rename the framework folder to anchor/, the symlink would also need to be anchor/, which conflicts with the submodule directory.

Options:

  1. Keep yue — no conflict, require 'yue'
  2. Rename submodule folder — e.g., anchor-engine/ instead of anchor/, then framework can be anchor/
  3. Different name — call the framework something else like eng or a

What do you prefer?

Does renaming the submodule folder affect anything?

Not really. It's just paths that need updating:

  1. .gitmodules — change the path entry
  2. Symlink — would point to anchor-engine/engine/anchor/ (or whatever)
  3. Running the exe — anchor-engine/engine/build/anchor.exe instead of anchor/engine/build/anchor.exe

It's just renaming. The submodule itself doesn't care what folder it's cloned into.

So if you rename the submodule to anchor-engine/, then:

Want to go this route?

Rename it to "engine", then, and "yue" to "anchor". Change any scripts required to make this consistent for next games, including the new-game script.

I need to clarify one thing. The Anchor repo structure is:

Anchor/
├── engine/
│   ├── src/anchor.c
│   ├── yue/           # → renaming to anchor/
│   ├── tools/
│   └── build/

If the submodule is called engine/, the paths become:

game/
├── engine/                    # Submodule (whole Anchor repo)
│   └── engine/                # The engine folder inside
│       ├── anchor/            # Framework (was yue/)
│       └── build/anchor.exe
├── anchor/                    # Symlink → engine/engine/anchor/

So we get engine/engine/ nesting. The exe path would be engine/engine/build/anchor.exe.

Is that okay, or would you prefer a different submodule name to avoid the double engine/?

Wouldn't that be only on the game side of things? This won't affect anything in the Anchor folder, right?

Correct. The Anchor repo stays:

Anchor/
├── engine/
│   ├── anchor/        # (renamed from yue/)
│   ├── build/
│   └── ...

The engine/engine/ nesting is only on the game side because the submodule folder name + the internal structure. If that's acceptable on the game side, we can proceed.

Changes needed:

  1. Rename engine/yue/ to engine/anchor/ (in Anchor repo)
  2. Update compile-yue.bat paths
  3. Update new-game.sh to use engine/ as submodule name and create anchor/ symlink
  4. Fix the symlink in emoji-ball-battles

Want me to proceed?

Oh, but yue/ has to be renamed to anchor/ in the Anchor folder?

Yes. For require 'anchor' to work, Lua needs to find anchor/init.lua.

The symlink in the game (anchor/) points to the framework folder in the Anchor repo (engine/anchor/). So the Anchor repo folder must be named anchor/.

Current: engine/yue/require 'yue' After: engine/anchor/require 'anchor'

Perhaps we shouldn't have the submodule + symlink option, this seems to complicated and not flexible. What are the alternatives?

Perhaps we shouldn't have the submodule + symlink option, this seems to complicated and not flexible. What are the alternatives?

Alternatives:

  1. Modify package.path in C — The engine adds its own framework path to Lua's search. Game just does require 'object', no symlinks needed. Engine knows where it lives.

  2. Embed framework in exe — Framework .lua files baked into anchor.exe at compile time. No external framework files at all.

  3. Copy framework to each game — Simple but manual. Updates require copying.

  4. Monorepo — Games and engine in same repo. Simple paths, no submodules.

  5. Engine auto-loads framework — Engine loads framework from its own directory before running game code. Game doesn't explicitly require it.

Option 1 or 5 seem cleanest — the engine handles finding its own framework files, games don't need to know where they are.

Which appeals to you?

Explain option 1 in more detail.

Option 1: Modify package.path in C

The engine knows where its own executable is. On startup, it computes the framework path relative to itself and adds it to Lua's package.path.

Example:

Engine exe: E:/a327ex/Anchor/engine/build/anchor.exe Framework: E:/a327ex/Anchor/engine/anchor/

In anchor.c, after initializing Lua: c // Get path to exe, compute framework path relative to it // Add to package.path: "E:/a327ex/Anchor/engine/anchor/?.lua" luaL_dostring(L, "package.path = 'E:/a327ex/Anchor/engine/anchor/?.lua;' .. package.path");

Game side:

emoji-ball-battles/
├── main.yue
├── assets/

No symlinks, no submodule needed. Game just runs: bash E:/a327ex/Anchor/engine/build/anchor.exe .

Game code: yuescript require 'anchor' -- Engine finds it via modified package.path

Bundled release: Framework files go into the zip alongside game files. Engine detects bundle mode and adjusts paths.

Benefits:

I would like people who download only the game repo to be able to run it from that folder alone, this would break it, right?

Right. If someone clones just the game repo, they need the engine + framework somehow.

Submodule + package.path (no symlink):

The submodule still provides the engine, but instead of a symlink, the engine modifies package.path to find its own framework:

game-repo/
├── engine/              # Submodule (Anchor repo)
│   └── engine/
│       ├── anchor/      # Framework
│       └── build/anchor.exe
├── main.yue

Engine startup (in C) computes framework path relative to the exe:

Game code still does require 'anchor' — no symlink needed, engine handles it.

Benefits:

Only downside:

Does this approach work for you?

With the submodule idea, we still need to pull everytime there's a change, right?

Yes. Every time Anchor changes, you'd need to:

  1. Update the submodule: git submodule update --remote
  2. Commit the new submodule reference

This is annoying during active development when you're changing both engine and game frequently.

Alternatives:

  1. Monorepo — Games live inside the Anchor repo (e.g., Anchor/games/emoji-ball-battles/). No submodules, changes are immediate.

  2. Local dev, submodule for release — During development, use package.path pointing to your local Anchor. Submodule only matters for others cloning the repo.

  3. Just copy the exe + framework — No submodule at all. When you want to update, copy anchor.exe and engine/anchor/ into your game. Simple but manual.

Given you're the primary developer and actively working on both engine and games, a monorepo might be simplest — no submodule friction, everything in one place.

What's your preference?

I think... Let's just have the Anchor folder not care at all about yue files. While that is still an "engine" concern, for now, let's do the entire development of it in emoji-ball-battles. This means that the Anchor folder just produces the anchor.exe file, and the emoji-ball-battles folder should it. We can make it so that whenever we build anchor.exe, we also copy it to the tools/ folder in emoji-ball-battles. Then running the game in emoji-ball-battles is just calling tools/anchor.exe, right?

That's much simpler:

Anchor repo — just produces anchor.exe, no YueScript code Anchor/ ├── engine/ │ ├── src/anchor.c │ ├── build/anchor.exe │ └── build.bat # Also copies exe to emoji-ball-battles/tools/

emoji-ball-battles — has everything: framework, game code, tools emoji-ball-battles/ ├── tools/ │ └── anchor.exe # Copied from Anchor build ├── anchor/ # Framework (init.yue, object.yue, etc.) ├── main.yue # Game code

Running: bash tools/anchor.exe .

Benefits:

Want me to:

  1. Remove engine/yue/ and engine/tools/ from Anchor
  2. Set up anchor/ and tools/ in emoji-ball-battles
  3. Update build.bat to copy exe to emoji-ball-battles

Yes, do all that, and also fix the emoji-ball-battles repo because it has symlinks, submodules, etc. There are some folders that also have README.md files with what will be outdated comments. There's also new-game script, which does a bunch of things, but it should be changed to accomodate for this new setup. The new-game script should also have an option to copy the anchor/ "gameplay" code from the previous project. Sometimes I may be working on multiple projects at once, which means that files for the YueScript Anchor code will have to be copied around those multiple folders, but most of the time it will be sequential, from emoji-ball-battles, to the next game, to the next, so the next game simply has to copy the YueScript Anchor code from the previous one. Or do you see a way for these YueScript Anchor files to be copied around multiple games without having to use submodules or symlinks?

For sharing YueScript files across multiple games without submodules/symlinks:

Option: Central location in Anchor repo

Keep the framework in Anchor/framework/anchor/ (separate from engine/). The new-game script copies from there. When you finish a game and improve the framework, you copy it back to Anchor.

Anchor/
├── engine/           # C code only
│   └── build/anchor.exe
├── framework/        # YueScript framework (master copy)
│   └── anchor/
│       ├── init.yue
│       └── object.yue

Workflow:

For parallel development, you'd manually sync or run a script to copy from whichever game has the latest.

Does this work, or do you prefer strictly copying from the previous game?


Let me first check what needs cleaning in emoji-ball-battles:

Let's do this, in the original Anchor code, which you can see in reference/love-compare, an is an object because then, in the update loop, we use "an" as the object that we collect all objects from. So this whole code you wanted to add, we can actually "reuse" it to be the same code that's used in ALL objects. Does this make sense? It's an elegant way of solving this problem of setting up the loop. This means that all this code should go into object.yue, with the appropriate names, i.e. instead of collect, it would be get_all_children, or whatever we decided that would be, because it's the same code that's used for normal objects since every object is the same in the tree. If you understand, please say so, but before proceeding, ask clarifying questions.

Yes, I understand. Instead of a separate update loop that treats an specially, the collection/update logic becomes methods on the object class itself. Since an is just an object, and every object can have children, any object can:

So the C side just calls an:update(dt), and the object class handles everything internally.

Clarifying questions:

  1. Should I look at reference/love-compare to see how the old Anchor did this, so I can match the method names and patterns?

  2. For the method that collects all descendants — what should it be called? Options from the Phase 10 doc mentioned all(tag) / A(tag) for querying by tag. Is this the same method, or separate?

  3. The C side currently calls a global update(dt) function. Should we change it to call an:update(dt) instead, or should the global update function just delegate to an:update(dt)?

The C side just calls update, it has no concept of "an". That's handled on the Lua side entirely.

  1. Sure, but that code is the old version for a reason, deviate where necessary depending on what we decided this time.
  2. I believe it's the same method? Just tagless it probably collects everything, which would make sense to me.
  3. No, just update, and then inside that we do whatever is needed to make things work.

Got it. Let me look at the old Anchor code first.

     4→  Thus, every object can do everything every other object can, with very few exceptions.

    10→      self:object('player', args)

    17→  In this example, the "player:new" function is the player class' constructor, and the "player:update" function is the update function that gets called every frame.
    18→  Objects can also be named, and in the example above "self:object('player', args)" names this object's .name attribute to 'player'.
    19→  In general, if you're going to name an object, that name should be unique, because names get used to organize objects in parent/child relations so that they can be more easily referred to by names.
    20→
    21→  The second way of creating objects is anonymously/locally:

Now I understand the old Anchor pattern. The key insight is:

  1. get_all_children() is a method on object that collects all descendants
  2. The global update loop calls an:get_all_children() to get all objects
  3. Then iterates through them for early/main/late/cleanup phases

So the structure would be:

object.yue: ```yuescript global *

class object new: (name) => @name = name @parent = nil @children = {} @dead = false @tags = {}

-- Get all descendants, optionally filtered by tag all: (tag) => nodes = {} stack = {} for i = #@children, 1, -1 table.insert stack, @children[i] while #stack > 0 node = table.remove stack if not node.dead if tag table.insert nodes, node if node.tags[tag] or node.name == tag else table.insert nodes, node for i = #node.children, 1, -1 table.insert stack, node.children[i] nodes ```

Then init.yue creates an, and the global update function uses an:all().

Should I also include _early_update, _update, _late_update methods on object (like the old code), or keep those as separate functions in init.yue that just check for user-defined early_update/update/late_update methods?

For now let's test that this works every frame. Just add all, add and then let's test that things are being gathered properly. Please check your logic for the .dead checks in all, since we decided on slightly different logic for death semantics this time, but I don't remember it the changes apply here or not. Read relevant documents if you need, some of them might be in reference/archives.

Let me check the death semantics we decided on.

92-The C engine calls into Lua each frame with a specific order. This is foundational — the action system, object methods, and built-in objects all depend on this execution model.
93-
94-**Frame execution order:**
95:1. **Collect** — Traverse tree, gather all non-dead objects
96-2. **Early phase** — Run `early_update` methods, then early actions
97-3. **Main phase** — Run `update` methods, then main actions
98-4. **Late phase** — Run `late_update` methods, then late actions
99:5. **Cleanup** — Remove dead objects, call `destroy` hooks

The death semantics from Phase 10 plan:

  1. kill() immediately sets .dead = true on self AND all descendants (synchronous)
  2. Actual removal at end of frame
  3. Children never outlive parents

So in all():

My logic is correct. Let me write the minimal files:

Write (E:\a327ex\Anchor\game\object.yue)

The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). To tell you how to proceed, the user said:
technically, this will also capture objects that have their .name attribute as equal to the tag, isn't that confusing?

You're right, that's confusing. all(tag) should only match tags, not names. If you want an object by name, you'd access it directly (@player) or use a find method.

The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). To tell you how to proceed, the user said:

Everything is set up correctly. Here's the summary:

Completed:

  1. ✓ Removed engine/yue/ and engine/tools/ from Anchor repo
  2. ✓ Created Anchor/game/ with master framework files (init.yue, object.yue)
  3. ✓ Updated build.bat to copy exe to emoji-ball-battles/tools/
  4. ✓ Cleaned emoji-ball-battles (removed submodule, symlinks, .gitmodules, setup.bat)
  5. ✓ Set up emoji-ball-battles with tools/ (anchor.exe, yue.exe) and anchor/ (framework)
  6. ✓ Updated new-game.sh with --from option to copy framework from previous game
  7. ✓ Tested all() collection — works correctly in DFS left-to-right order

New structure: ``` Anchor/ ├── engine/ # C engine only │ └── build/anchor.exe ├── game/ # Master framework (copied to new games) │ ├── init.yue │ └── object.yue

emoji-ball-battles/ # (and future games) ├── tools/ │ ├── anchor.exe │ └── yue.exe ├── anchor/ # Framework (local copy) │ ├── init.yue │ └── object.yue ├── main.yue # Game code ```

Ready to continue with Phase 10? Next would be expanding the object class (add, kill, tag, etc.) and the update loop.

Create a new document in Anchor/docs that contains everything we did so far, without including any next steps. Simply describe, however you decide, you use checkboxes or not, based on everything that transpired. It doesn't need to a be a summary, just something that next Claude instances can go from to understand the current structures, what we did, what we decided on etc.

Write (E:\a327ex\Anchor\docs\PHASE_10_PROGRESS.md)

File created successfully at: E:\a327ex\Anchor\docs\PHASE_10_PROGRESS.md

Created docs/PHASE_10_PROGRESS.md. It covers:

Ok, before we end the session commit and push the new emoji-ball-battles folder.

Bash (cd E:/a327ex/emoji-ball-battles && git status)

The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). STOP what you are doing and wait for the user to tell you how to proceed.

Actually, lets to the end session workflow, title it "Anchor Phase 10 Part 1", and after you're done with the main Anchor folder, also commit + push the emoji-ball-battles folder, but use the same title + summary for the commit message that was used for the Anchor folder, makes sense?

    11→1. **Locate the session transcript** — find the most recent JSONL file
    12→2. **Convert to Markdown** — use a lowercase, hyphenated title slug (e.g., `engine-phase-1.md`). Date-based filenames don't work with Blot.
    13→3. **Read the converted log** to review the full session, especially if compacted. Summary must cover everything.
    14→4. **Write a detailed summary:**
    15→   - Chronological order (matching conversation flow)
    16→   - Weight to one-off fixes, attempts, problems solved
    17→   - Specific details: error messages, what was tried, what worked
    18→5. **Create a short title** (max 30 characters)
    19→6. **Show title + summary to user** — wait for approval before proceeding
    20→7. **Prepend title + summary** to the log file (replace default header)
    21→8. **Sync context files**
    22→9. **Commit** with title as subject, full summary as body:
