Single-script builder (nosignal.sh) that turns a stock Arch Linux ISO into a fully-offline installer for a themed Hyprland + caelestia (Quickshell) desktop: matching SDDM greeter, Btrfs/Limine bootable snapshots, chwd-style GPU detection, and a curated "os updates" layer (keybind cheatsheet, settings panels, system polish, on-box management skill). See README.md. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# nosignal-keybinds-gen — parse the NoSignal keymap markdown and emit display-ready
|
|
# cheatsheet lines on stdout. The markdown is the SINGLE SOURCE OF TRUTH; the
|
|
# on-screen help (nosignal-keybinds) is always derived from it, so the two cannot
|
|
# drift. Reads every "| keys | action |" table row except the "Source map"
|
|
# section.
|
|
#
|
|
# Panel format: two columns only — key, action — sized so every
|
|
# line fits the fuzzel panel:
|
|
# - no section tag column (visual noise in the popup; the markdown keeps it)
|
|
# - doc-only parentheticals are stripped from actions: provenance notes like
|
|
# "(Omarchy key)", "(was hover-only)" belong in the doc,
|
|
# not the panel. Meaningful ones ("(logout / shutdown / reboot)") stay.
|
|
# - actions are ellipsis-truncated so no line exceeds $NOSIGNAL_KEYS_COLS
|
|
# characters (default 98 — the nosignal-keybinds fuzzel width of 100 minus
|
|
# margin). Keep the two in sync.

# Usage: nosignal-keybinds-gen [path-to-markdown]

# Source resolution order: $1 arg → $NOSIGNAL_KEYMAP_MD → known locations.
