The ICPC Tools are a set of tools to support running programming contests. For the latest downloads, please go to the ICPC Tools website.

Each of the ICPC tools can be used individually, or together in any combination. They are all designed to support the REST-based Contest API as defined by the Competitive Learning Initiative (CLI). Some features require extensions to the specification, and those are described here.

These tools were built to support the International Collegiate Programming Contest (ICPC) World Finals and have been used there for many years, but the intention is that they are usable for local and regional contests as well.

The ICPC Tools are built to work with any Contest Control System (CCS) that supports the REST-based Contest API.

To be more specific, the only part of the Contest API that is strictly required is the event feed and any file references that the feed refers to. If your CCS correctly supports the event feed, then all of the ICPC Tools will work even if the rest of the API is not implemented. The one exception to this is the CDS' and contest utility support for comparing scoreboards - to compare a scoreboard, the CCS must have one, of course!

The CDS also retains support for the deprecated XML Event Feed, Mirror. If your CCS supports this feed as specified then the tools should still work with a CDS in the middle, albeit with some missing function.

The most popular CCSs that have been tested and successfully used at multiple contests with the ICPC Tools are listed here:

The ICPC Tools are developed, tested, and maintained by a group of ICPC volunteers. Bug reports, feature requests, and even just knowing what worked or didn't for your contest are always appreciated. Pull requests are also welcome, but if you want to implement a big feature it might be best to first create an issue to discuss it.

To become a committer you must have a history of high quality bug reports, PRs, and be approved by the ICPC Tools team.

You can use Eclipse to develop and debug the ICPC Tools. We will add information on how to run and debug later.

See the IntelliJ IDEA specific documentation.

A Docker image is provided to run the CDS without having to install it yourself.

The basic way to run it, is to run

docker run --name cds --rm -it  -p 8080:8080 -p 8443:8443 -e CCS_URL=https://www.domjudge.org/demoweb/api/contests/nwerc18 -e CCS_USER=admin -e CCS_PASSWORD=admin ghcr.io/icpctools/cds:2.2.407

Replace https://www.domjudge.org/demoweb/api/contests/nwerc18 with your CCS contest API URL, CCS_USER with a user with admin privileges to the CCS URL, CCS_PASSWORD with the password for the given user and 2.2.407 with the version of the CDS you want to run.

Now you can access the CDS at https://localhost:8443/.

Note: this will use default credentials for all users, so it is recommended to change them. This can be done using environment variables or overwriting the users.xml file.

• ADMIN_PASSWORD: the password for the user with admin privileges.
• PRESADMIN_PASSWORD: the password for the user with presentation admin privileges.
• BLUE_PASSWORD: the password for the user with blue privileges.
• BALLOON_PASSWORD: the password for the user with balloon privileges.
• PUBLIC_PASSWORD: the password for the user with public privileges.
• PRESENTATION_PASSWORD: the password for the user with presentation privileges.
• MYICPC_PASSWORD: the password for the user with MyICPC privileges.
• LIVE_PASSWORD: the password for the user with Live privileges.
• CCS_URL: the URL to a CCS contest.
• CCS_USER: the user that has admin access to CCS_URL.
• CCS_PASSWORD: the password for CCS_USER.

• If you want to supply your own users.xml, mount a file at /opt/wlp/usr/servers/cds/users.xml.
• If you want to supply your own cdsConfig.xml, mount a file at /opt/wlp/usr/servers/cds/config/cdsConfig.xml.

The contest data directory is located at /contest so you can mount that as a volume if you want to store the data or use team photos, organization logos, banners or any other files.

All of the tools are provided under the included license and are "Free as in Beer". We welcome you to use and enjoy them, but if you ever run into anyone who has contributed to them - Tim, John, Nicky, Sam, Troy, etc. we would greatly appreciate it if you'd buy us a beer, a stroopwafel, or some other suitable token!
