This is the core library for Libanius. The purpose of Libanius is to aid learning. Basically it presents "quiz items" to the user, and for each one the user must select the correct answer option. Quiz items are presented at random according to a certain algorithm based on spaced repetition. An item has to be answered correctly several times before it is considered learnt.
The core use is as a vocabulary builder in a new language, but it is designed to be flexible enough to present questions and answers of all types.
The implementation is in Scala. The main target platforms are the Web and Android.

Usually Libanius will be run through an interface such as https://github.com/oranda/libanius-scalajs-react, but a console UI is provided in this project. Get a copy of
git clone, From SBT, type:
Pick the option
com.oranda.libanius.consoleui.RunQuiz and try out a sample quiz.
This has been tested with Scala 2.12.6, Java 8, and sbt 1.1.2.
A better standalone CLI is available at https://github.com/oranda/libanius-cli-zio.
Making Your Own Quizzes
If you need to learn a subject, consider making a quiz for it. You need to write a quiz file. The format is simple. Just study the sample quiz files in the
data/resources folder. Look at the first line. You can see that each question is asked a certain number of times depending on the
numCorrectResponsesRequired parameter, and multiple-choice is used the first x times, where x is set using the
The quiz files in
data/resources have the
.txt extension. If a user exits a quiz before finishing it, the state is saved in a
.qgr file in the
data folder. This will be read on running libanius again. Remember to delete
.qgr files if you want to start from the beginning.
Whenever the user answers a question correctly, it is said that s/he has moved up a "memory level" with respect to that item. The number of memory levels for a quiz is equal to
In any quiz file, quiz items are grouped into "partitions", where each partition corresponds to a memory level. You will observe that in the initial quiz file (
.txt), all quiz items are in the first partition. As the user makes progress, quiz items are moved to other partitions, and you can observe this effect by quitting a quiz and looking at the persisted form, i.e. the
If you learn something using your own quiz file, and feel it is a success, consider submitting it to this project (e.g. via a PR) so that other people may learn too.
