Hellion Forge

**Version 1.4.7** — Privacy-first chat plugin for FINAL FANTASY XIV / Dalamud, built on [Chat 2](https://github.com/Infiziert90/ChatTwo) (EUPL-1.2). Hellion Chat is a privacy-first plugin built on the Chat 2 foundation. The majority of the engine comes from Chat 2 (message store, channel logic, hook system), and most keyboard shortcuts continue to work as you'd expect. What changes: stricter privacy defaults out of the box, custom slash commands under `/hellionchat`, no web interface, and as of v1.1.0, a theme engine as a step toward a distinct UI look and feel. The data-handling focus is on GDPR/EU, US, and JP regulations, as far as practically applicable for a chat plugin: per-channel retention periods, granular filters, and self-service data export. A full breakdown is available in [`PRIVACY.md`](PRIVACY.md). This is a standalone repository, licensed under EUPL-1.2. With v1.0.0 the standalone cut is complete: own namespace `HellionChat.*`, own IPC channels, own source tree structure. Distribution via custom repo. Active upstream sync ended with the v1.4.x cycle: Chat 2 is undergoing a fundamental rework and cherry-picks are no longer portable. From here, Hellion Chat continues as an independent codebase — background and attribution in [`docs/UPSTREAM_SYNC.md`](docs/UPSTREAM_SYNC.md). ## Acknowledgements Hellion Chat is built on [Chat 2](https://github.com/Infiziert90/ChatTwo) by **[Infiziert90 (Infi)](https://github.com/Infiziert90)** and **[Anna](https://github.com/anna-is-cute)**, who maintained the plugin for years before I ever saw the source code. The entire core architecture, the message store, the channel logic, the hook system, and much more all come from them. If Hellion Chat helps you, the credit for that belongs in large part to Infi and Anna. A full acknowledgement is in [NOTICE.md](NOTICE.md). Hellion Chat is developed under **Hellion Forge**, the specialized modding and plugin branch of [Hellion Online Media](https://hellion-media.de). --- ## Tech Stack | Category | Technology | | ------------ | --------------------------------------------------- | | Platform | Dalamud Plugin (API Level 15) | | Language | C# 13 / .NET 10 (`net10.0-windows`) | | Build | Dalamud.NET.Sdk 15.0.0, DalamudPackager 15.0.0 | | UI | Dear ImGui (Dalamud bindings) | | Database | SQLite (Microsoft.Data.Sqlite, MessagePack storage) | | Localization | ResX (HellionStrings.resx, .de.resx; PR-based) | | Font | Exo 2 (SIL Open Font License 1.1, bundled) | | Toolchain | dotnet 10 SDK, VS Code with C# Dev Kit | | Deployment | GitHub Releases + custom repo (`repo.json`) | --- ## Features ### Privacy / Compliance - **Channel whitelist** for database persistence with privacy-first defaults. Out of the box, only your own conversations are stored (tells, party, FC, linkshells, cross-world linkshells, alliance, ExtraChat). Public chat, NPC dialogue, system spam, and battle logs are discarded at the storage layer. - **Per-channel retention periods** with a daily background cleanup. Tells: 365 days, own conversation channels: 90 days, global default: 30 days. The default is OFF — the plugin deletes nothing without explicit consent. - **Retroactive cleanup** with preview and Ctrl+Shift confirmation. Applies the current whitelist to an existing database, runs in the background, and calls VACUUM afterward. - **Export** to Markdown, JSON, or CSV via the Dalamud file dialog (GDPR Art. 15 right of access). Filter by channel, date range, or sender substring. - **Full privacy overview** in [`PRIVACY.md`](PRIVACY.md) and third-party components in [`docs/THIRD_PARTY_NOTICES.md`](docs/THIRD_PARTY_NOTICES.md): what is stored, which two outbound calls exist (BetterTTV opt-out, Square Enix Lodestone font), an explicit no-telemetry statement, and the mapping of GDPR rights (Art. 15/17/18/20/21) to concrete plugin functions. ### Onboarding - **First-run wizard** with three profiles (Privacy-First, Relaxed, Full History) and a GDPR notice for the "Full History" option. - **Configuration migration** seeds privacy defaults for existing users and shows a notification on the first plugin start after an update. With v1.0.0, users on config version 12 or older also receive a one-time tab layout reset; the old tab configuration is backed up as `pluginConfigs/HellionChat.json.pre-v13-backup`. - **Layout migration from Chat 2** moves configuration and database to `pluginConfigs/HellionChat/` without data loss. Handles locked files gracefully (warns the user if Chat 2 is still loaded). - **Migrate3 recovery** heals partially migrated databases from old Chat 2 installations. ### Look & Feel - **Bilingual UI** (English and German) with live language switching. Hellion-specific strings are in `HellionStrings..resx`. - **Hellion HUD theme** with cyan-teal accents, slate-violet tabs, and amber highlights for active states. - **Chat color presets** (v0.6.0) with seven built-in bundles in Settings → Appearance → Chat Colors: Classic (Chat 2 default), High Contrast, Pastel, Dark Mode Tuned, Hellion (brand), plus bonus moods Night Blue and Indigo Violet. One-click apply, battle channels remain untouched. - **Window opacity slider** for combat-friendly transparency. - **Bundled Hellion font** (Exo 2, OFL-1.1) as an optional default instead of the system font. - **Hellion logo** bundled in the plugin and displayed in the Dalamud plugin list. #### Custom Themes (v1.1.0) HellionChat ships a theme engine with ten built-in themes (Hellion Arctic, Hellion Spectrum, Chat 2 Classic, Event Horizon, Crystal Nocturne, Mint Grove, Night Blue, Indigo Violet, Forge Merchantman, Synthwave Sunset) and a JSON-based authoring format for custom themes. Schema and step-by-step guide in [`docs/THEME-AUTHORING.md`](docs/THEME-AUTHORING.md). Hellion Spectrum is Deuteranopia/Protanopia-safe (red-green color blindness) based on the Wong/Okabe-Ito palette. #### Plugin Integrations (v1.3.0) - **Honorific custom titles in the chat header.** When the Honorific plugin is active and a custom title is set, it is displayed in the chat header above the message log. Auto-detect with silent fallback: without Honorific the slot is invisible. Toggle in Settings → Integrations → Honorific. First cycle of a multi-stage plugin integration roadmap (context menu, NotificationMaster, RP status, ExtraChat, and XIVIM to follow). ### Pop-Out Convenience (v0.6.0) - **Input bar in pop-out windows** as a global opt-in in Settings → Windows → Window Frame. When active, every pop-out window has a compact input at the bottom with a channel-colored icon button and text field. No more switching back to the main window for a quick reply. - **Per-pop-out independent text buffer and history cursor.** Changing channels in a pop-out works globally like in the main window (FFXIV channel API), but half-typed input doesn't collide between the main window and pop-outs. - **Shared input history** across all windows via singleton service. Up/Down arrow keys navigate the same list of the last 30 entries everywhere. ### Stability - BetterTTV cache crash fix (null key handling). - Font atlas build fallback for missing system fonts. - Defensive wrapping of all migration operations. ### What's missing compared to Chat 2 The web interface was removed in Hellion Chat 0.2.0. It serves a different use case than the focus of this fork — remote access to chat from a second device — which conflicts directly with the privacy-first premise: a chat plugin that starts a local HTTP server is too large an attack surface for my threat model. So it's gone. If you want the full Chat 2 feature set, the upstream plugin serves you better. Hellion Chat is deliberately the slimmer fork. --- ## Architecture ```text HellionChat/ ├── Privacy/ │ └── PrivacyDefaults.cs # Whitelist sets, per-channel retention table ├── Export/ │ └── MessageExporter.cs # Markdown / JSON / CSV serializer ├── Resources/ │ ├── HellionStrings.resx # Hellion-specific UI strings (EN) │ ├── HellionStrings.de.resx # German translation │ ├── HellionStrings.Designer.cs # Hand-maintained accessor │ ├── ChatColourPresets.cs # Seven built-in color presets (v0.6.0) │ ├── HellionFont.ttf # Exo 2 variable font │ ├── HellionFont-OFL.txt # OFL-1.1 license text (bundled with font) │ └── Language*.resx # Upstream localization (Crowdin) ├── Ui/ │ ├── FirstRunWizard.cs # Three-profile onboarding │ ├── HellionStyle.cs # ImGui theme push (local and global) │ └── SettingsTabs/ │ └── Privacy.cs # Privacy tab (filters, retention, cleanup, export) ├── Ipc/ # IPC channels, migrated to HellionChat.* in v1.0.0 ├── ChatTwoConflictDetector.cs # Blocks plugin load if upstream Chat 2 is active ├── images/ │ └── icon.png # Hellion logo (256×256) ├── HellionChat.csproj # SDK Dalamud.NET.Sdk/15.0.0 └── HellionChat.yaml # Plugin manifest (DalamudPackager source) ``` ### Rules - **Code namespace is `HellionChat.*`.** Fully consolidated onto the plugin name since v1.0.0 — no remaining `ChatTwo.*` anywhere in the source tree. - **AssemblyName is `HellionChat`.** Own slot in `pluginConfigs/`, own file manifest, no shared state with Chat 2. Parallel-loading upstream Chat 2 is actively blocked on startup (bilingual conflict message). - **IPC channels are `HellionChat.*`.** Six channels for third-party plugin integration (`Register`, `Available`, `Unregister`, `Invoke`, `GetChatInputState`, `ChatInputStateChanged`). Details in [`docs/IPC.md`](docs/IPC.md). - **Hellion-specific strings in `HellionStrings.*.resx`**, strings carried over from Chat 2 in `Language.*.resx`. The original `Language.*.resx` structure is preserved because the existing translations from the upstream Crowdin community remain valuable. - **No direct access to `Plugin.Interface.UiBuilder.FontAtlas`** outside of `FontManager`. Font fallback and the Hellion font are managed centrally. --- ## Database SQLite, schema inherited from upstream Chat 2 (migration level v3). Hellion extensions live in `Configuration` as fields, not in the DB schema: | Column | Type | Description | | ---------------- | ------- | ---------------------------- | | Id | BLOB | Guid | | Receiver | INTEGER | Receiver ContentId | | ContentId | INTEGER | Sender ContentId | | Date | INTEGER | Unix timestamp (ms) | | ChatType | INTEGER | XivChatType / LogKind | | SourceKind | INTEGER | Player / NPC / Server / etc. | | TargetKind | INTEGER | Player / NPC / Server / etc. | | Sender | BLOB | MessagePack `List` | | Content | BLOB | MessagePack `List` | | SenderSource | BLOB | MessagePack `SeString` | | ContentSource | BLOB | MessagePack `SeString` | | ExtraChatChannel | BLOB | Guid | | Deleted | BOOLEAN | Soft-delete marker | Path: `pluginConfigs/HellionChat/chat-sqlite.db`. WAL mode, Synchronous=NORMAL. --- ## Installation Hellion Chat is distributed via a Dalamud **custom repository**. ### Fresh install (no prior Chat 2) 1. Open Dalamud Settings (`/xlsettings`) → **Experimental**. 2. Add a new entry under **Custom Plugin Repositories**: ```text https://gitea.hellion-forge.cloud/JonKazama-Hellion/HellionChat/raw/branch/main/repo.json ``` 3. **Save**, then go to `/xlplugins` → **All Plugins** → Refresh. 4. Hellion Chat appears in the list — install it like any other plugin. ### Migration from Chat 2 (with existing history) Chat 2 and Hellion Chat share the database file until Hellion Chat moves it to its own path on first start. Order matters: 1. **Disable Chat 2** in `/xlplugins` (do not uninstall, just disable). 2. **Fully close FFXIV** so SQLite releases the file lock. A plugin reload alone is not enough. 3. Restart the game. 4. Add the custom repo as described above. 5. Install Hellion Chat. On first start, the configuration file and the entire database directory are moved into the HellionChat layout. 6. **Verify** under Settings → Privacy → Refresh preview that the message count looks plausible. ### Troubleshooting **Hellion Chat shows 0 messages, even though Chat 2 was active before:** Migration was blocked by a locked file. Close the game and move the files manually: Linux / XIVLauncher Core: ```bash mv ~/.xlcore/pluginConfigs/ChatTwo/chat-sqlite.db \ ~/.xlcore/pluginConfigs/HellionChat/chat-sqlite.db [ -d ~/.xlcore/pluginConfigs/ChatTwo/EmoteCacheV1 ] && \ mv ~/.xlcore/pluginConfigs/ChatTwo/EmoteCacheV1 \ ~/.xlcore/pluginConfigs/HellionChat/ ``` Windows / XIVLauncher: ```powershell Move-Item "$env:AppData\XIVLauncher\pluginConfigs\ChatTwo\chat-sqlite.db" ` "$env:AppData\XIVLauncher\pluginConfigs\HellionChat\chat-sqlite.db" -Force ``` Start the game, enable Hellion Chat, and your history is back. ### Updates Updates appear automatically in the plugin list once a new `vX.Y.Z` tag with a GitHub Release is published. No reinstall needed. --- ## Distribution Hellion Chat is distributed via its own Dalamud custom repository (`repo.json` in the repo root). Pushing a `vX.Y.Z` tag triggers the [`release.yml`](.github/workflows/release.yml) workflow, which attaches the build output (`HellionChat/bin/Release/HellionChat/latest.zip`) along with the matching changelog block from `HellionChat.yaml` to the GitHub Release. Manual recovery path if the auto-trigger is missed: `gh workflow run release.yml -f tag=vX.Y.Z`. An optional submission to the Dalamud main plugin repo (in addition to the custom repo) is on the [roadmap](docs/ROADMAP.md). --- ## Project Status **Version 1.4.7** — Backlog cleanup and the first user-visible feature bundle since v1.4.5. TempTell tabs can now be pinned via right-click; pinned tabs survive relog, keep their conversation history (loaded on demand from the message store), and stay bound to the same `/tell` partner. A hard cap of 5 pinned tabs lives in a pool separate from the 15-tab auto-tell pool, so the total ceiling is 20 tabs. The sidebar groups pinned tabs into their own section with its own divider header. Honorific glow outlines now render when the title carries a Glow colour — opt-in via **Settings → Integrations → Render glow outlines (Honorific)**, default off, so v1.4.6 visuals stay untouched for users who don't care and the per-frame DrawList overhead is skipped on low-end hardware. Honorific gradient (Color3 / GradientColourSet / Wave / Pulse) is parsed and stashed for a later cycle, but currently renders as the primary colour. Sidebar width is configurable in **Theme & Layout** between 44 and 160 px; default stays icon-only so existing users see no layout change. `Configuration.UpdateFrom` now preserves the runtime `CurrentChannel` across the persistent-tab merge, and `TabSwitched` deep-clones the seeded channel — together they fix a Settings-Save regression where the chat input could pop back to `/tell ` after touching settings while on a Party or Linkshell tab. Internal items: `IPluginLogProxy` indirection over Dalamud's `IPluginLog` routes all ~91 `Plugin.Log` call sites through a testable proxy, closing the test-isolation gap F12.1 left in v1.4.6 (`MessageStore.Migrate0` now runs in xUnit without loading `Dalamud.dll`). `Util/ImGuiUtil.cs`'s `DrawArrows` IconButton id gets explicit parentheses on the increment. Migration v16 → v17 is additive (new `Tab.IsPinned` flag, default false). Eighth sub-patch of the v1.4.x polish sweep series (as of 2026-05-13). Hellion Chat is a standalone plugin, no longer a fork in the repository sense. Fully completed: - Privacy filters (whitelist, retention, retroactive cleanup, export) - First-run wizard with three profiles - Plugin identity: own `HellionChat` slot, layout migration from Chat 2, Migrate3 recovery - Bilingual UI (EN and DE) with live language switching - Hellion theme, Hellion logo, bundled Exo 2 font - Custom repo pipeline with automated GitHub Release distribution - Slash commands consolidated to the `/hellionchat` family - Web interface removed (v0.2.0) - Audit hardening (path traversal, retention race, DbViewer consistency) - About tab in Hellion branding, localized EN and DE, with license and disclaimer - AI disclosure documented (see [`docs/AI_DISCLOSURE.md`](docs/AI_DISCLOSURE.md)) - Standalone cut: namespace `HellionChat.*`, IPC channels `HellionChat.*`, source tree restructure, conflict detection against upstream Chat 2, SQLite CVE hardening (3.50.3) - Theme engine with ten built-in themes plus JSON authoring format (engine v1.1.0, catalog extended in v1.2.3, including CVD-safe Hellion Spectrum; Synthwave Sunset in v1.4.1) - ABGR cache on theme records: `HellionStyle.PushGlobal` reads pre-computed ABGR instead of converting RGBA→ABGR per slot per frame (v1.4.1, ~13% render-time recovery) In progress: incremental modernization of UI look and feel beyond the theme engine. What's planned next and what's on the long-term list is in [`docs/ROADMAP.md`](docs/ROADMAP.md). Concrete scheduled items are also tracked in the [Gitea issue tracker](https://gitea.hellion-forge.cloud/JonKazama-Hellion/HellionChat/issues) under the `roadmap` label. ### On Release Cadence Anyone looking at the repo for the first time will notice a lot of releases and a high commit count in a short time. Both are deliberate. The full reasoning — four factors behind it — is in [`docs/LEARNING-JOURNEY.md`](docs/LEARNING-JOURNEY.md), section "How I release this fast". --- ## Community & Support - **Hellion Forge Discord** (community for HellionChat and other Hellion Online Media plugins and tools): [discord.gg/X9V7Kcv5gR](https://discord.gg/X9V7Kcv5gR) - Bug reports and feature requests: [Gitea Issues](https://gitea.hellion-forge.cloud/JonKazama-Hellion/HellionChat/issues) - Discord DM: `@j.j_kazama` - Further contact options (security, privacy, quick questions): see [SUPPORT.md](SUPPORT.md) --- ## License EUPL-1.2 (same license as upstream Chat 2).
