lys-lib

Non-widget building blocks for the lys family, in pure Go.

Documentation

  • Rendering and GPU: a 2D canvas with CPU and Vulkan renderers, dmabufs, DRM.
  • Wayland: screen capture, virtual input, XKB, protocol bindings.
  • Media: H.264/H.265 hardware encoding, MP4/Matroska muxing, Opus, Vorbis, V4L2.
  • System: a PipeWire video producer, an EIS server, D-Bus helpers, PAM.

Builds with CGO_ENABLED=0. libvulkan, libva and libpam are dlopened at run time where used.

Install

Example

Package v4l2 streams a V4L2 capture node in pure Go (mmap buffers over golang.org/x/sys/unix ioctls), delivering each frame as an RGBA picture letterboxed to a requested aspect, and names the capture nodes a system has.

Package vinput injects pointer, keyboard and touch input into the compositor through zwlr_virtual_pointer_v1, zwp_virtual_keyboard_v1 and lys_virtual_touch_v1, on a private Wayland connection: the input half of a remote-desktop bridge, and of lys-ui's own headless test harness.

Package wltest helps tests run Wayland clients: a private runtime dir, a loopback display for wire-level tests with no compositor, a fake compositor serving linux-dmabuf feedback over one, and, against the headless compositor the test recipes boot, a client that puts solid-colored surfaces on screen for capture tests to find.

Package wmipc is the wire contract of lys-wm's IPC socket: JSON lines, each request answered by a Response, and a watch stream of events.

Package xcursor reads Xcursor files and resolves cursor themes the way libXcursor does: XCURSOR_PATH, theme inheritance and nominal sizes.

Package xdg resolves the XDG base directories and user directories: the base directories themselves, the search paths they form, and an app's own directory under each, all read from an Env.

xkb
Package xkb is a pure-Go implementation of the XKB keyboard model: compiling keymaps from rules, model, layout, variant and options, parsing and serializing keymap text in the xkb_v1 and libxkbcommon v2 formats, tracking modifier, layout and LED state, composing keysym sequences into text, and reading keymaps from an X server.

internal/genkeysyms command
Command genkeysyms writes the xkb package's keysym tables: the names come from libxkbcommon's xkbcommon-keysyms.h, and the canonical names, the Unicode conversions and the case mappings from asking libxkbcommon itself, so the tables are the library's own answers.

registry
Package registry lists the models, layouts, variants and options a ruleset offers, from xkeyboard-config's XML files, the way libxkbregistry does.

x11
Package x11 is a minimal X11 client for xkb.SetupX11: a connection to an X server over its Unix socket, authenticated from the Xauthority file, that carries requests with one reply each.
