Versions are synced with Sigil releases. A missing entry indicates no changes for that version.

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.10.2] - 2026-09-21

Added

  • The mouse wheel. (mouse-wheel) answers the wheel's vertical travel since the last frame and (mouse-wheel-x) the horizontal, in GLFW's units (a notch is 1.0 on most mice; vertical + is away from the user), summed over the frame from GLFW's scroll callback and cleared with the other per-frame input. Without a window both answer 0.0. Wanted by Crash The Stack's tracker (the wheel scrolls the pattern; David, 2026-09-21).

[0.10.1] - 2026-09-20

Added

  • The rest of the keyboard. key-down?, key-pressed? and key-released? now know f1..f25, page-up/page-down, home/end, insert/delete, right-shift/right-ctrl/right-alt, caps-lock, the punctuation row (comma period slash semicolon apostrophe minus equal left-bracket right-bracket backslash grave, or the character itself as a symbol) and the keypad (kp-0..kp-9, kp-enter, kp-add, kp-subtract). The 0.10.0 names are unchanged. Wanted by Crash The Stack's tracker, whose FastTracker key model needs the function keys, paging and the punctuation row natively.
  • (key-code key): the GLFW key code a symbol names, or #f for a name that is no key; needs no window, so a program can check a binding before it is used and the symbol table is testable (test/test-keys.sgl).

[0.10.0] - 2026-09-20

The package is now sigil-desktop, and the window is GLFW instead of sokol_app.

Changed

  • Native Wayland on Linux. GLFW 3.5.1 is vendored as source under vendor/glfw (no local patches, VENDOR.md has the pin and inventory). One binary runs as a Wayland client or under X11, picked at startup; SIGIL_DESKTOP_PLATFORM=wayland|x11 forces it. Under sokol_app the Linux window was always X11 (XWayland on a Wayland desktop).
  • No platform libraries linked. GLFW loads libwayland-client, libxkbcommon, libX11 and friends, libEGL and libGL at run time; the Linux link-flags are empty (were -lX11 -lXi -lXcursor). A game's NEEDED list loses those three.
  • Framebuffer pixels follow the output scale. On a Wayland output at scale 2 a window asked for at 800x600 has a 1600x1200 framebuffer; frame-width/frame-height report it and mouse-x/mouse-y are in the same pixels. Fractional scales work. A program with hard-coded pixel coordinates should lay out from frame-width and frame-height. On X11 nothing changes.
  • The library is (sigil desktop). (sigil app) remains as a re-export for this release only.
  • app-run raises app-run: could not open a window (exit 1) when no display platform or GL context is available; sokol_app aborted.
  • (quit-requested?) answers #t inside the frame the close button was pressed in, not only in cleanup.
  • The frame clock restarts after the init procedure, so a long asset load is not the first frame's delta time.
  • GL 4.3 core is requested on Linux and Windows and 4.1 on macOS, as before; the window has no default icon (sokol_app drew one).

Added

  • include/sigil-desktop.h: sigil_desktop_framebuffer_size, sigil_desktop_gl_get_proc_address, sigil_desktop_platform, the C surface sigil-graphics builds its swapchain and GL loader on.
  • src/c/dl-search.c: a dlopen that finds runtime libraries in Guix and Nix profile directories (SIGIL_LIBRARY_PATH, $GUIX_ENVIRONMENT/lib, nix-shell inputs, $NIX_LD_LIBRARY_PATH, the user and system profiles), with test/dl-search-test.sh.
  • guix/run-wayland.scm, guix/run-x11.scm, guix/build.scm.
  • SIGIL_DESKTOP_VERBOSE=1 for startup, resize and library-resolution diagnostics.

Removed

  • vendor/sokol (sokol_app, sokol_time, sokol_log) and the sapp_* symbols. sigil-graphics 0.11.4 no longer links them.

Requires

  • Sigil 0.20+ as before. Building on Guix needs the X11 and Wayland headers in guix/build.scm (libx11, libxcursor, libxrandr, libxinerama, libxi, libxext, xorgproto, wayland, libxkbcommon).

Upgrade notes

  • Relock at the new URL. The Codeberg repository is sigil/sigil-desktop since 2026-09-20 (renamed in place, the old URL redirects): write (from-git url: "codeberg:sigil/sigil-desktop" version: "^0.10.0") on your own window dependency line. The transitional form the tag notes describe, (from-git url: "codeberg:sigil/sigil-app" name: "sigil-desktop" ...), still works through the redirect; a line with neither the new URL nor name: beside a sigil-graphics 0.11.4 installs the repository twice (sigil-app 0.9 beside sigil-desktop 0.10, two window stacks, a duplicate slog_func at link time), because sigil-build keys a dependency by the name it derives from the URL.
  • Delete the consumer's build/ once (a stale sokol-app.o otherwise stays in the old archive), then rename (sigil app) imports to (sigil desktop) before 0.11.

[0.9.0] - 2026-06-25

Changed

  • Raised the toolchain requirement to Sigil 0.17. The package now declares sigil: "^0.17" and pins sigil-stdlib to ^0.17. Sigil 0.17 makes the package-level sigil: field mandatory and derives the native codegen runtime (sigil-lib) from it, so building under the 0.17 compiler requires this bump. This is a minor release because consumers caret-pinning sigil-app must move to the 0.17 line.

Requires

  • Sigil 0.17+ (sigil-stdlib / sigil-lib 0.17 line).

[0.8.4] - 2026-04-24

Fixed

  • link-flags: now uses (lambda (ctx) (case (target-os ctx) ...)) instead of a host-based (case (host-os) ...) expression. The host-based form evaluated at package-load time on the host, so Linux link flags (-lX11 -lXi -lXcursor) leaked into Windows cross-compile builds; sigil build --config windows-amd64 from a Linux host would fail at the final link against zig's MinGW sysroot. The procedural form re-evaluates at link time with the target triple. Branches themselves are unchanged (linux: -lX11 -lXi -lXcursor; darwin: -framework Cocoa -framework QuartzCore; windows: -lkernel32 -luser32 -lshell32 -lgdi32).

Requires

  • sigil-build 0.14.0+ (for the target-os / target-arch helpers and the procedural-link-flags dispatch in collect-native-link-flags).

[0.7.0] - 2026-03-01

Added

  • Added procedure specifications with inline (: ...) syntax, optional runtime checking via sigil-checks feature, and predicate combinators (any-of, maybe, list-of, none-of).
  • Added procedure specs and docstrings to all exported procedures.
  • Added procedure specs and docstrings to all exported procedures.

[0.5.0] - 2026-02-17

Added

  • Added test harness generation and build support for packages with native dependencies. Improved native package handling, added c-flags field to library struct. Fixed stdlib inclusion in bundles with custom native runtimes, directory structure preservation in compile-c-sources, and absolute sigil-lib include path resolution.
  • Added test coverage.
  • Added test coverage.

Fixed

  • Fixed random seed initialization crash caused by flonum-to-bignum promotion in modulo. Fixed status command crash when displaying projected versions for packages without changes.

Other

  • New packages split from sigil-studio. Font and image modules moved to (sigil graphics *) namespace.
