An ICPC-style programming contest system.

Built on top of:

• CodeIgniter
• Bootstrap
• Moe Contest Environment

Testimonial

I needed a judging system for programming contest and spent days and nights on looking for one. Then I found Regrader - one of the best programming contest management systems on the internet. It's an open source project and extremely easy to install!

What I loved about the system is its flexibility and user-friendliness. With just a few clicks you are able to make a fully custom design of your Regrader page, suiting your needs. Moreover the system itself is stable and reliable.

Do what I did - try Regrader, you won't regret it!

Installation Guide

1. Install dependencies

Regrader requires these packages. Please install them.

• PHP >= 5.6
• MySQL

2. Download Regrader

Download a copy of the latest Regrader: https://github.com/fushar/regrader/releases/download/v3.0.0/regrader-v3.0.0.tar.gz

3. Configure Regrader

Create an InnoDB database in your MySQL database server.

Then, make a copy of .env from .env.example:

$ cp .env.example .env

And edit each entry of .env based on your system configuration:

• ENCRYPTION_KEY denotes the encryption key that will be used by CodeIgniter. It is advisable that the string consists of 32 random characters.
• DB_HOSTNAME denotes the hostname of the database server.
• DB_USERNAME and DB_PASSWORD denotes the user credentials of the database.
• DB_NAME denotes the database name that will be used by Regrader.
• CPP_CHECKER_COMPILER_PATH denotes the C++ compiler path that will be used to compile checker source code (e.g., /usr/bin/g++). If you don't wish to use checker at all, leave it empty.

Finally, make sure your php.ini file has date.timezone option set.

4. Install Regrader

Open Regrader in your browser, and perform the installation steps as instructed. If at any step the system cannot install at some specified directories, please add write permission on them.

5. Run the grader engine

Execute run_grader.sh script on your host:

./run_grader.sh

Configuring the System

1. Change admin password

Open Manage->Users. Edit admin user and change the password to something else.

2. Configure programming languages

Open Manage->Languages. There will be 4 programming languages set up by default: Pascal, Java, C++, and C. For each language you want to actually use, you have to at least edit its compile command as necessary depending where you install the compiler.

3. Configure additional options

Open Manage->Options and configure additional properties of the system.

• Website, Top, & Bottom Names To be shown in the header.
• Left, Right 1, Right 2 Logo Filenames To be shown in the header. If set, the logo files must be uploaded in Manage->Files.
• Items per Page The number of rows in a table. Used in the list of users, problems, submissions, etc.

Using the System

After installation, you can log in and add users, contests, problems, etc. The interface should be quite intuitive to use :)

Miscellaneous

Solution checker

You can set up a solution checker for your problems. This is useful for problems that can have multiple solutions. The template for a checker can be found here: https://github.com/fushar/regrader/blob/develop/examples/checker.cpp.

Internationalization

Regrader currently supports English and Indonesian. To change the language to Indonesian, open application/config/config.php and change the value of $config['language'] into 'indonesian'.

Institution logos

You can show institution logos beside the contestant names in the scoreboard. The scoreboard will look very nice. Just upload X.jpg in Manage->Files as the logo for institution X. Then, tick the option Show Institution Logos in the corresponding contest's setting.

Public files

You can use Manage->Files to upload public files, for example, for inserting images in problem statements.

Public raw scoreboard

Besides the usual public scoreboard, you can also generate public scoreboard that is separated from the system. This is useful for hiding the contest URL address from the public and in order to minimize traffic and external attack.

• Download the public raw scoreboard HTML file from the admin scoreboard menu.
• Copy the assets/ directory.
• Publish both in a separate address.

Of course, to achieve a semi-live scoreboard, you have to do the above steps periodically, possibly using a script.

Got any weird errors?

Here are common suggestions that should solve most possible errors:

• Make sure that you have set up compile commands in programming languages you want to use.
• Make sure that your server has execute permission on moe/obj/box/box.
• Make sure that your test case output files have '\n' as the line ending.
• Make sure that your test case files have extensions.
• Make sure that run_grader.sh is running.
