Quera-Bundle is a set of python scripts to facilitate the use of the Quera project, including converting the Quera results file into CSV files and plotting them, setting the default languages for the assignments, and a simple test case generator for the assignments.
Quera is a technology company that aims to create a community of developers, educate them, and help them find the perfect job. Its online judge system is the sequel of Sharif-Judge --a free and open-source online judge for C, C++, Java, and Python programming courses-- developed by Mohammad Javad Naderi in 2014. Thereafter, it has been used as a main platform by most of the Persian-Language universities to automate the evaluation of programming assignments. These days, Quera is hosting lots of contests and challenges in Iran.
You can use the pip program to install the dependencies on your own. They are all listed in the requirements.txt file.
To use this method, you would proceed as:
pip install -r requirements.txt
To make Firefox work with Python selenium, you need to install the geckodriver. The geckodriver driver will start the real firefox browser and supports Javascript.
CentOS/Fedora users should install tkinter:
yum install python3-tkinter
When we set an assignment, we should set the acceptable languages for each problem manually. When you copy a set of problems from [Quera Question's Bank], it is really annoying to set the wanted languages one by one. The qbsetlang makes this process automatica.
The script needs the user and password to login into http://quera.ir in order to open the assignment. Each assignment has a specific URL: https://quera.org/course/assignments/<number>/problems. The <number> should be passed to the script.
python qbsetlang <number> -u <username> -p <password>
It will open the assignment with the PySelenium and gets the languages from the user for the first problem and then applies it to the other problems.
The number of assignemt.
The username/password of quera to login.
The program saves the chosen languages into
config.yamlfile and then reuses it afterward without any question. To reconfigure the desired languages, the--configoption should be used. It also saves theusernameandpasswordinto the config file, thususerandpassare mandatory for the first run.
The
passwordwould be encrypted by a universally unique identifier generated byuuidmodule. By this option, a user-defined string will be used for encryption/decryption instead of the default.
By default, a
tkinterwindow is used to get the desired languages. With this option, the script will use the terminal to get them.

The qbgentest makes the in and out folders containing the test cases and their solutions in an acceptable format for Quera. It gets the name of the solution program as the input of TestCase class constructor and it assumes that the name contains a number that will be used in the name of input and output folders, respectively in{num} and out{num}. Then the created object would be called with the input including the \n to separate each line of the input.
If you run the Makefile in shell, it will run the qbgentest.
Running the following command packs all test case folders in zip files for uploading to Quera.
$ make zip
At first, download the assignments' grades via quera in XLSX format. Then, just run the qbcompmark in the folder containing those files. It will create a CSV file that includes all marks from all assignments and their sum. It also plots the summation for each student in a single graph depicting their attempts during the semester.
