Marvin ee3f30e502 docs: update sidebar and documentation to include greg hooks registry
- Added new items to the sidebar for 'greg-hooks-and-events' and 'greg-hooks-registry' under the Framework and Reference categories, respectively.
- Enhanced the documentation layout by including references to the greg hooks registry in various guides and topics, improving accessibility to hook-related information.
- Updated descriptions in the documentation to clarify the purpose and usage of the greg hooks and their registry.

This commit aims to improve the visibility and usability of the greg hooks registry within the documentation.

FMF hook and event naming

Target format

All new public hook and event identifiers should follow:

FMF.<Domain>.<EventOrHook>
  • FMF — Fixed prefix (Greg Mod Framework / gregFramework hook namespace).
  • <Domain> — Uppercase domain from the approved domain list. Describes where the signal belongs in the game (player, rack, server, economy, …).
  • <EventOrHook>PascalCase segment(s), usually OnSomething for events or a verb phrase for commands.

Examples (illustrative): FMF.RACK.CableSpinnerColorResolved, FMF.PLAYER.InputPoll, FMF.NETWORK.Cable.OnConnected.

Approved domain segments

Domains are closed by default. Add a new domain only via changelog + maintainer review.

Domain Scope
GAMEPLAY Rules, scoring, simulation beats not covered elsewhere
PLAYER Local player input, camera, UI focus
EMPLOYEE NPC staff, hiring, schedules
CUSTOMER Contracts, SLA, satisfaction
SERVER In-game server racks, VMs, power
RACK Physical rack placement, mounting
NETWORK Cables, switches, traffic
STORE Shop cart, checkout
WORLD Rooms, expansion, walls
UI HUD overlays, menus (when not PLAYER)
SAVE Save/load lifecycle
FRAMEWORK Loader, bridge, diagnostics

Runtime IL2CPP (MelonLoader): greg.*

Harmony patches in gregFramework emit stable greg.<DOMAIN>.<Action> strings via GregHookName / GregEventDispatcher. That surface is documented in greg hooks registry (IL2CPP) (greg_hooks.json, regeneration, overlap with hand-written HarmonyPatches). It is separate from the FMF.* / FFM.* documentation constants below.

Legacy: FFM.* strings in code

The runtime currently maps numeric event IDs to FFM.* string constants in FrikaMF/HookNames.cs (e.g. FFM.Economy.Balance.OnChanged). That is legacy naming (four segments after FFM).

Policy

  • New documentation and greenfield APIs should use FMF.<Domain>.* as above.
  • When touching HookNames.cs, prefer aligning new entries to FMF.*; otherwise keep FFM.* until a planned major version bump documents a rename map.
  • The generated hook catalog lists what the code emits today (including FFM.*).

Cross-language stubs (documentation)

For each canonical hook, the wiki may add non-normative snippets:

Language Convention
C# FMF.Domain.OnSomething.Subscribe(...) or string literal
Lua FMF.Domain.OnSomething:subscribe(...)
Rust fmf::domain::on_something::subscribe(...)
Python fmf.domain.on_something.subscribe(...)
TypeScript FMF.Domain.OnSomething.subscribe(...)

Bindings are not auto-generated for all languages; stubs are for contributor clarity.
