when

Run on every visit after the condition qualifies for a finite positive time in seconds. False resets timing; changing time preserves the true interval. Monotonic gaps, holds and skipped branches count. Nonblocking; no checks are scheduled. Use if for immediate conditions and nest once for one-time runtime-section work.

Syntax

when(condition, time=seconds):

Available in

• Executable DCode bodies

Native C++

Uses fixed retained timer state; repeated qualification does not sleep, schedule work or allocate.

Example

when(condition, time=0.5):
    -- body
