Operators without arguments

Values that the compiler gives to the program.

Every program can use these operators. No import is necessary.

Operator	Arguments	Gives
create_immutable_array	—	[T]
create_immutable_hash	—	[K
current_directory	—	string
error_msg	—	string
install_directory	—	string
M_PI	—	double
poll_keypress	—	string
random	—	double
shell_arg_cnt	—	int
wall_clock_ms	—	double

Target support marks

• ✔Own template
• ✱Default template
• ✕No template

The operator works for a target with an own template and for a target with the default template. The default template is the * entry of the definition: it writes the same code for every target that has no template of its own. A target with no template writes no code, and a program that uses the operator does not compile for that target.

create_immutable_array

(create_immutable_array) → [T]

wall_clock_ms

(wall_clock_ms) → double

Wall-clock milliseconds since the Unix epoch, as a DOUBLE so sub-millisecond fractions are preserved. Used by embedders that want Date.now() / performance.now() to advance (e.g. Octane); the TS engine's default hostNowMs stays frozen for reproducible conformance. Integer-ms casts (duration_cast<milliseconds>, Date.now(), UnixMilli) floor every delta to 1 ms and pin Octane scores to a few discrete buckets — keep the fractional form.
