A minimum working example comparing concurrency syntax in Java, C++, Rust, Python, Go and Erlang.
IMPORTANT NOTE: The code implements a toy-stopwatch for didactic reason of syntax comparison between these programming languages using built-ins as much as possible. To achieve this, the stopwatch is not meant to be accurate or address thread-safety when scaled (especially Java and Python case).
- Maximum 3 threads or processes:
- counter - fast counting time base for the timer,
- refresh - console printout stopwatch format HH:MM:SS:Ms by converting counts from counter,
- read_input - (typically main thread/process) reading user console inputs
- <r> reset count
- <q> quit,
- counter thread/process must run uninterrupted by signaling from refresh thread/process,
- only allowed to use built-in blocking time counting calls (e.g sleep),
- not allowed to make system time checking calls,
- accuracy of keeping time is of little interest (primary purpose is syntax comparison).
- minimum dependencies,
- minimum lines of code.
