- Update .gitmodules URL from manaflow-ai/ghostty to Jesssullivan/ghostty - Submodule at 90a26469 with GHOSTTY_PLATFORM_LINUX in embedded.zig (Jesssullivan/ghostty#1) and #undef linux macro fix (#2) - Update docs/ghostty-fork.md: document patch #8 (linux Platform variant) and switch header from manaflow-ai to Jesssullivan
12 Zig source files implementing the full M5a Terminal MVP scope: Sprint 1 - Foundation: - main.zig: GtkApplication + libghostty init/wakeup/tick integration - app.zig: Runtime callbacks (action, clipboard, close_surface) - surface.zig: GtkGLArea + GHOSTTY_PLATFORM_LINUX surface creation - c_api.zig: @cImport bindings for GTK4, libadwaita, ghostty.h - config.zig: JSON config parser matching macOS schema (427 lines) - build.zig: Links libghostty.so + GTK4 + libadwaita + OpenGL Sprint 2 - Core UI: - window.zig: AdwApplicationWindow + AdwTabView + AdwTabBar - tab_manager.zig: Workspace list mapped to AdwTabView pages - split_tree.zig: Binary tree split pane model with GtkPaned - workspace.zig: Workspace data model (panels, title, color, status) - sidebar.zig: AdwNavigationSplitView + GtkListBox workspace list Sprint 3 - Platform Integration: - socket.zig: Unix domain socket JSON-RPC server (XDG paths) - session.zig: Session snapshot/restore (autosave 8s, atomic writes) Compiles and links on Ubuntu, Fedora 42, and Arch Linux. Closes #77, #78, #79, #80, #81, #82, #83.
linux-ci.yml: Add libghostty build (-Dapp-runtime=none -Drenderer=opengl) and cmux-linux build steps to all 3 Linux jobs (Ubuntu, Fedora, Arch). Add font/rendering deps (freetype, harfbuzz, fontconfig, libpng, mesa). Add zig build test step for config parser unit tests. fork-ci.yml: Build GhosttyKit.xcframework from source instead of downloading from manaflow-ai/ghostty releases. Uses native target for faster CI builds.
Verify GTK4 + libadwaita runtime libs are present in the NixOS VM. Stepping stone toward full graphical cmux-linux tests (blocked on Nix packaging of the libghostty build chain). Update basic-window-check-gnome TODO to reflect PR #104 progress.
