Eberban is a logical constructed language aimed to satisfy the following goals :

• being simple : the Eberban grammar allows manipulating predicates with particles in a way that is close to the higher-order logic it translates into, while abstracting away the verbosity of explicitely providing variables as arguments of predicates.
• being regular : valid sentences are syntaxicaly unambiguous. Most grammar rules rely on particles which are organised in families, each starting with a unique prefix. Many additional patterns are shared between particles and predicate words to help learning groups of related words.
• being expressive : the grammar and core vocabulary focus on providing a simple framework, on top of which can be built abstractions, complex concepts and tools. Since those are built into Eberban itself, users can create their own tools and abstractions to express entirely new concepts.

Eberban take inspirations from Lojban and other logical languages, but try novel approaches to satisfy the above goals.

Most resources are hosted on GitHub pages, such as :

• parsers, which transform text into a tree structure, that can also be visualized as nested boxes.
• a dictionnary allowing to search words and their definitions.
• learning resources to discover the language grammar and concepts.

To build the dictionary and parser locally, you must have NodeJS and NPM installed. Open a terminal in the node folder and run once the following command:

npm i

After every change in the node folder or in the dictionary, run the following command to build:

npm run build

To open the web pages in your browser you need to run an HTTP server in the root folder, for exemple using miniserve. You can then browse the local web site at http://127.0.0.1:8080/index.html .

To add a new word in the dictionary, you must edit dictionary/en.yaml and create a new entry for your word. You should set the id field to INSERT_WORD_ID, and then run the command npm run ids in the node folder so that INSERT_WORD_ID is automatically replaced with a random unique ID.

Books are made using mdbook and a few extensions which are written in [Rust]. First install Rust then run the following commands to install the required binaries:

cargo install mdbook
cargo install mdbook-linkcheck
cargo install mdbook-regex-replacer

You can then open a terminal in the book folder (in which book.toml is located) and run mdbook serve. This will run a web server that will reflect changes that you make in the .md files.
