Lap Timer Software or Script NEEDED!

dezireduser · 04-25-2007, 03:30 PM

Hello everyone,

I'm sorry if this sounds like a stupid question but I've tried searching and haven't been able to find a suitable answer.

Is there a timer software with an unlimited lap feature for linux or as a java applet?
Something like this lap timer.

If not, then what's the quickest way to make a simple script that will record the time whenever a key is pressed.

What I basically want to do is start a timer and then whenever I press the space bar, have:
1. the time elapsed since the last press
2. the time elapsed since the timer was started

recorded into a text file. I want to have this repeated an unlimited number of times.

So, the generated text file should look something like this:

#HH:MM:SS.sss = hours:minutes:seconds.seconds
#ELAPSED----------LAP

00:00:00.000----------00:00:00.000
00:00:00.675----------00:00:00.675
00:00:01.775----------00:00:01.100
00:00:34.000----------00:00:32.225
00:00:37.500----------00:00:03.500
00:21:11.000----------00:20:33.500
00:21:12.000----------00:00:01.000
00:59:59.000----------00:38:47.000
02:00:00.123----------01:00:01.123
02:00:01.453----------00:00:01.453
.
.
.

The way I'm doing this currently is binding an alias to the date command and having the output appended to a text file and then processing and formatting that data. Something that automatically does all this in one step would be great.

Thanks for any help and any pointers!

would something written in java be suitable I think I could code something up fairly easily.

This should do the trick, it'll tell you what to do when you run it. If you want to save the results just redirect it to a file.

Code:

import java.lang.Exception;
import java.text.SimpleDateFormat;
import java.util.Date;

public class LapTimer {

	public static void main(String[] arg){
		long glStart;
		long lapStart;
		char ch = ' ';
		SimpleDateFormat formatter = new SimpleDateFormat("KK:mm:ss:SSS");
		glStart = System.currentTimeMillis();
		lapStart = 0;

		System.out.println("# format is: Hours:Minutes:Seconds:Milliseconds");
		System.out.println("# Elapsed time, Lap Time");
		System.out.println("# press enter to end the current lap");
		System.out.println("# type 'q' and enter to quit");

		do{
			long elapsed,lapTime;

			if(ch != ' '){
				elapsed = System.currentTimeMillis() - glStart;

				if(lapStart == 0){ // if on first lap
					lapTime = elapsed;
				} else {
					lapTime = elapsed - lapStart;
				}
			
				System.out.print(formatter.format(new Date(elapsed)) + "," + formatter.format(new Date(lapTime)));
			
				lapStart = elapsed;
			}
			//ask for new control character

			try{
				ch = (char) System.in.read();
			}catch(Exception ex){
				System.out.println("Oh No!!!!");
			}

		}while(ch != 'q');
		
	}

actually I just tried redirecting it and it doesn't work too well.
