Project summary

JabRef is a popular open-source bibliography reference manager that helps researchers and academics organize and manage their references efficiently. This project aims to develop three things:

• A Cite As You Write (CAYW) endpoint that can be used as an alternative to Better-BibTeX's CAYW feature for Zotero which can run alongside JabRef or as a part of JabSrv (JabRefs' HTTP-server, which offers an API for working with the bibliographies opened in JabRef).
• A Language Server Protocol (LSP) server that provides different features for editing .bib, .bibtex, .md and .tex files in editors, including VSCode. Which can run inside JabRef or as a standalone server.
• A VSCode extension that integrates with the LSP server to provide a seamless experience for users working with bibliography files in VSCode. The VSCode extension connects to the running LSP server (or can start a standalone version if JabRef isn't running) and provides features such as integrity checks, hover information, jump to definition, select the key in JabRef (when running) or opening the CAYW endpoint.
