GeoPub

GeoPub is an ActivityPub client developed within the openEngiadina project.

History

GeoPub was started as a very simple JavaScript demonstrator to show how geographic information can be used over the ActivityPub protocol (see branch initial-js-demonstrator).

A second version was developed in ClojureScript (see branch cljs). The ClojureScript version was abandoned due to licensing and reproducability issues (it is hard to use GPL/AGPL for Clojure(Script) projects and Clojure support in Guix/Nix is not so good).

This (the third version) is implemented in OCaml using js_of_ocaml.

Hacking

A development environment can be created with Guix:

guix shell -D -f guix.scm

After this you can run dune build @install which will build GeoPub and place all necessary artifacts into _build/install/default/share/geopub/.

You may want to start a small webserver for local development (e.g. python3 -m http.server --directory _build/install/default/share/geopub/). This works very nicely when running dune in watch mode (dune build @install --watch).

Note that this uses dependencies from Guix. You might have to run guix pull to get the lastest dependencies from Guix. To use a version of Guix that has been tested use: guix time-machine -C channels.scm -- shell -D -f guix.scm.
