Xeppelin Contest Watcher

Xeppelin Contest Watcher

Xeppelin is a contest watcher software that keeps track of file modifications during a contest and creates visualizations of your activity.

Installation

pip install xeppelin

Workflow

1. Prior to the contest, create a new contest directory. Let's say it's called icpc-wf.
2. Run xeppelin start icpc-wf to start watching the directory.
3. Start the contest by writing a template file. Xeppelin team uses template.cpp.
4. When solving a problem, create a new file with the problem letter. For example, if you're solving problem A, create a file named A.cpp.
5. When you compile the code, use -o flag to specify the problem letter. For example, g++ A.cpp -o A.
6. After the contest, run xeppelin stop icpc-wf to stop watching the directory.
7. Looking through your submissions, you can see the time of each successful submission. Add them manually to the log file with xeppelin log icpc-wf "A solved 1:30".
8. Run xeppelin show icpc-wf to see the visualization and get the image on your disk.

Commands

• Start Watching: xeppelin start <contest_name> Starts watching the current directory for file modifications and logs them to <contest_name>.log.

• Stop Watching: xeppelin stop <contest_name> Stops watching for the specified contest.

• Show Visualization: xeppelin show <contest_name> [--duration MINUTES] [--freeze TIME] Displays a visualization of the activities logged for the specified contest.

  Options:

  • --duration MINUTES: Sets the maximum time (in minutes) to show on the visualization axis (default: 300)
  • --freeze TIME: Adds a freeze period indicator starting at specified time (format: HH:MM or minutes)

  Examples:

  xeppelin show icpc-wf --duration 240
  xeppelin show icpc-wf --freeze 4:00
  xeppelin show icpc-wf --duration 240 --freeze 180
  

• Log Submissions: xeppelin log-submissions <contest_name> <submission_info> Adds additional submission information to the log file for the specified contest. Usually should be used to log the time of the submission. Example:

  xeppelin log-submissions test "A solved 1:30"
  

• Help: xeppelin --help xeppelin <command> --help Shows help information about Xeppelin commands and their options.

Format

All problems are coded in files named A.cpp, B.cpp, etc. The compiled binary is named A, B, etc. Some additional files for the contest (stress-testing, additional solutions, etc.) are also allowed, if their filename starts with letter that matches the problem letter.

Requirements

• inotify-tools for file watching.
• Python packages: pandas, matplotlib, numpy.
• Verified to work on Ubuntu and WSL2.

sudo apt install inotify-tools

pip install pandas matplotlib numpy
