What It Does
Native Wayland screen recorder for wlroots-based compositors (sway, labwc, etc.). Captures frames via the wlr-screencopy protocol and encodes to MP4/MKV using system ffmpeg. Supports audio capture with --audio.
Note: Does NOT work on selkies-desktop — use wl-record-pixelflux instead (labwc nested in pixelflux can't deliver screencopy frames).
Usage
# a box composing this candy — the candy list is a child node
my-box:
candy:
base: fedora
my-box-candy:
candy:
- wf-recorder
CLI Usage
# Direct usage (inside container)
wf-recorder -f output.mp4 # Record to MP4
wf-recorder -f output.mp4 --audio # With audio
wf-recorder -f output.mp4 -r 60 # 60fps
# Stop with Ctrl-C
Integration with the record: check verb
Author record: plan steps (the declarative verb served out-of-process by
candy/plugin-record — no host charly check subcommand for it) and run them with
charly check live sway-browser-vnc --filter record. A record: start step with
record_mode: desktop auto-detects wf-recorder; desktop interaction is driven with the
wl:/cdp: verbs (which keep their host subcommands); record: stop + artifact:
copies the .mp4 out:
sway-rec-start:
check: a desktop recording starts
record: start
context: [deploy]
record_name: demo
record_mode: desktop
sway-rec-stop:
check: the desktop recording is captured
record: stop
context: [deploy]
record_name: demo
artifact: demo.mp4
artifact_not_uniform: true

Use when authoring or modifying a charly PLUGIN — a candy with a `plugin:` block that contributes Providers (verbs/kinds/deploy-targets/steps/builders/commands), its own CUE schema, builtin (compiled-in) or external (out-of-tree git repo). Covers the unified Provider model, the per-plugin CUE-schema contract (single source → Go params for dev + schema-over-Describe RPC for runtime), the SDK, and the loader.

The CUE data-validation / configuration CLI (cue), pinned to v0.16.1. Use when working with the cue candy, installing the cue binary into a box or onto a target:local dev host, or running the offline schema-vendoring pipeline that feeds charly's egress validation.

CUE EGRESS validation — validating (and, where it adds value, generating) the config files charly WRITES to a system BEFORE the bytes hit disk. MUST be invoked before working on charly/egress.go, the vendored schemas under candy/plugin-egress/egress-schemas/vendor/, the ValidateEgress / registerVendoredEgressKind path, the offline `task cue:vendor` pipeline, or adding an egress schema for any written artifact (cloud-init, k8s manifests, traefik routes, runtime config, install ledger, systemd/quadlet units, ssh_config, libvirt XML).

Kubernetes cluster-probe declarative check verb — the `kube:` check verb (nodes, pods, ingress, storage class, addon health, apply/delete, and arbitrary resource GETs) served out-of-process by the candy/plugin-kube plugin (vendored client-go; no external kubectl required).
