What changed

1. Common print-status footer. Three platform daemon installers each duplicated the same 5-line block at end:

echo "  ✓ Loaded into <platform> ..."
echo "  airc will now auto-start at login + restart on crash."
echo "  Logs:   $scope/daemon.log"
echo "  Status: airc daemon status"

Plus optional platform-specific notes (gh keychain for launchd, linger for systemd, etc).

After: one _daemon_install_done <lead> <scope> [note] helper. All three platforms call it. ~10 lines saved.

2. Trimmed duplicated comment context in _daemon_install_schtasks. Function body had 30+ lines of comment paragraphs explaining the history of why we cd / use bash -c / use Unix-form path / why HKCU not schtasks. That context belongs in commit messages (#200, #202) — keeping it in the source duplicates information and bloats the function. Trimmed to a 4-line summary that points at PR #202 for detail. ~30 lines saved.

Behavior

Unchanged on every platform. Same plist/unit/.bat content rendered, same registration commands, same output text (just printed via the helper). bash -n airc clean.

Pull request overview

Refactors the airc daemon install platform installers to reduce duplication by centralizing the shared “install complete” output into a helper, and trims verbose historical comments in the Windows daemon installer section.

Changes:

• Adds _daemon_install_done helper to print a common “daemon installed” footer.
• Updates launchd/systemd/Windows daemon install functions to call the helper instead of duplicating footer output.
• Replaces long explanatory comment blocks in _daemon_install_schtasks with a shorter summary referencing prior PRs.

The helper’s header comment says the optional trailing note is passed as $2, but the function actually treats $2 as scope and reads the note from $3. Please fix the comment (or the signature) so callers don’t accidentally swap scope/note arguments later.

Suggested change

	# any optional trailing note as $2 (heredoc-style multi-line OK).

printf ' %s\n' "$note" won’t indent multi-line notes as implied by the comment (“heredoc-style multi-line OK”): embedded newlines in $note will print without the leading two spaces on subsequent lines. If multi-line notes are intended, split/loop over lines (or otherwise normalize indentation) before printing.

Suggested change

	local lead="$1" scope="$2" note="${3:-}"
	echo " ✓ $lead"
	echo " airc will now auto-start at login + restart on exit."
	echo " Logs: $scope/daemon.log"
	echo " Status: airc daemon status"
	if [ -n "$note" ]; then echo ""; printf ' %s\n' "$note"; fi
	local lead="$1" scope="$2" note="${3:-}" note_line
	echo " ✓ $lead"
	echo " airc will now auto-start at login + restart on exit."

	if [ -n "$note" ]; then
	echo ""
	while IFS= read -r note_line || [ -n "$note_line" ]; do
	printf ' %s\n' "$note_line"
	done <<< "$note"

PR description says the daemon installer output text is unchanged, but _daemon_install_done standardizes the messaging (e.g., “restart on exit”) and also hard-codes Logs: $scope/daemon.log, which removes previously platform-specific log hints (e.g., systemd’s journalctl --user -u airc -f). Either update the PR description to match, or extend the helper so each platform can preserve its prior user-facing output.

[Copilot]

On Windows, the install output previously included additional actionable paths/commands (daemon.err, launcher path, and airc daemon uninstall). Switching to _daemon_install_done drops that guidance, which is user-visible behavior change (and contradicts the “same output text” claim). Consider passing a Windows-specific note/extra footer lines so users still see where restart events go and how to stop/uninstall.
