◆ is_valid_script_filename()

bool sequencer::is_valid_script_filename ( const std::string & name )

True when name is a safe bare script filename: ^[A-Za-z0-9_-]+.script$, no separators.

References ok.

◆ load_dynamic_states()

ScriptLoadResult sequencer::load_dynamic_states	(	const fsw::config::Config &	cfg,

		const ScriptLoadContext &	ctx )

Resolve, load and validate every [[states]] entry carrying a script_file.

Never throws and never partially applies: a state either comes back fully usable or fully refused with a reason fit to show an operator.

◆ parseHoldMs()

bool sequencer::parseHoldMs	(	const std::string &	text,
		uint32_t &	out )

inline

Parse a hold duration off the wire, strictly.

Strictly, because the lenient version of this is a hazard: atoi("1e3") returns 1, so a frame asking for a thousand seconds would have quietly run a one-millisecond pulse and the operator would have weighed a mass against a window that never happened. The whole string must be digits.

Rejects: empty, non-digits, a leading sign, trailing junk, anything over kMaxHoldMs, and zero — zero is the "no duration supplied" sentinel everywhere else, so it must never arrive as one.

Parameters

out	written only on success.

Returns: true if text is a usable duration.

◆ kMaxHoldMs

uint32_t sequencer::kMaxHoldMs = 3600000

inlineconstexpr

Hard ceiling on any client-supplied hold, independent of per-state config.

This is not the real limit — each holdable state carries its own, usually far smaller, max. This one exists so a typo or a garbage frame is rejected at the wire before it reaches anything that has to reason about it.

Definition at line 16 of file HoldParse.hpp.

Referenced by main(), and parseHoldMs().

◆ kMaxScriptTimeoutMs

uint32_t sequencer::kMaxScriptTimeoutMs = 600000

inlineconstexpr

Hard ceiling on script_timeout_ms, independent of per-state config.

Same posture as HoldParse's kMaxHoldMs: this is not the real limit — each state carries its own, usually far smaller — it exists so a typo cannot arm a valve-open window measured in hours.
