Changelog

2026-09-12 — WebAssembly examples

Wasm plugins

  • Added four WebAssembly info providers, one per language, each with an xfetch-plugin.json manifest and capabilities declared explicitly:
    • wasm-crypto — Rust core module quoting BTC/ETH/... through the allowlisted HTTP host call.
    • wasm-ip-geo — Python component (componentize-py) showing public IP, location, network and timezone from ipapi.co.
    • wasm-pacman — Go core module counting repository vs AUR packages via allowlisted pacman exec, using the Go wasm host bridge (//go:wasmimport///go:wasmexport).
    • wasm-proc — freestanding C core module (no wasi-libc) reading load average, uptime and memory from a read-only /proc preopen.
  • Added scripts/ci-wasm.sh: local CI that builds every example with whichever toolchains are installed.
  • Fixed the broken swap glyph in the animate-logo layout_dots_full.jsonc preset (U+FFFD replaced with nf-md-swap_horizontal).

2026-08-19

Timeout Standard

  • All plugins now wrap their work in with_timeout with an own runtime budget (2–25 s); on timeout they respond with fallback lines or exit gracefully, so a hung plugin can never hang xfetch.
  • A plugin without a runtime limit is rejected — enforced by CI (ci/unix.sh, ci/windows.ps1, running on Linux, macOS and Windows). PRs must pass CI.
  • Requires xfetch-plugin-api with with_timeout (see the api repo).

Plugins (as of 2026-08-19)

  • animate-logo — logo animation for the daemon
  • chocolatey — count of packages installed via Chocolatey (Windows)
  • display-resolution — screen resolution
  • docker — container stats
  • github-stats — GitHub profile statistics
  • music-player — MPD/Spotify status
  • temperature — CPU/thermal zone temperatures
  • theme-detection — GTK theme detection
  • theme-manager — theme registry management
  • timezone — local time and UTC offset
  • user-info — user, host and groups
  • weather — weather via wttr.in

Each plugin has its own CHANGELOG with its specific budget and changes.
