Answering my own request for it might be resourceful for someone. I repeat: in a dev process, the goal here is to launch your IDE, open your web browser and start coding, period. For now, I decided to touch the
arangodb.conf file and change:
[database]
directory = /path/to/me/code/databases
uid = owner_of_code_path
[javascript]
app-path = /path/to/me/code/apps
I'm not really satisfied because on future release, this configuration file may need to be updated (erased). Anyway, it serves my purpose for now and maybe, in a couple of days, I will have to involve node deps and switch to an npm script solution that auto publishes code. Maybe an update like: foxx-manager publish command, being issued under a directory containing a manifest.json file, would grab a mount point from that name property and install / update the code while leaving any configuration file untouched, or better a foxx-manager watch will apply the dev-mode behavior + some extra logic to any place of an hard drive.
