I started to work on a CLI client for Friendica named friclicli. At the moment I'm working on the foundation of the client: A C library (called libfriclient) with functions representing Friendica API routes (one function per route). The client will use a curses interface (probably ncurses). To make requests to the Friendica API the libcurl library will be used. JSON data will be processed using the cJSON library.
The source code repository is here: https://gitlab.com/ncc1988/friclicli
The client will be programmed in C and licensed under the GPLv3+.
