adddev

Babashka script which adds a devcontainer configuration to a clojure project in current folder.

Usage

Basic usage is via

bb -m behrica.adddev.main

But as the script acts on local folder, it makes more sense to have it installed in some form in your computer, using bbinfor example.

Running the script creates a local folder .devcontainer with a devcontainer.json including Clojure, babashka and lsp.

You can add the following parameters to add support for python or R into the devcontainer. This updates as well deps.edn.

parameter	description
:with-R	adds R and clojisr
:with-python	adds python and clj-libpython and a nrepl start script which runs nrepl in a configured venv

nrepl.sh

When the python support is activated, the script creates as well a nrepl.sh script, which combines the setup of the venv via poetry and the nrepl start via clj in one commmand. This makes sure, that the clojure process starts with the activated venv, which makes libpython-clj automatically find the correct python environment at initialisation.

Using the appropiate poetry and clj commands this could as well be done more manual.

From zero to clojure nrepl including usage of python

With Emacs

Assuming you have

neil
devpod
add-devcontainer installed as adddev with bbin

you can get from "zero" to a clojure + python enabled devcontainer running nrepl (with working python bindings via libpython-clj ) on port 12345 via:

neil new scratch foo
cd foo/
adddev :with-python
chmod +x nrepl.sh
devpod up .
devpod ssh .
./nrepl.sh

As devpod will forward port 12345 to your host, you can do cider-connect to localhost:12345 with Emacs (or any other nrepl based IDE)

All changes of python packages listed in pyproject.toml will be picked-up and sychronized with the used venv when you stop/start nrepl.sh

With VSCode and Codespaces
