RUSE Userspace System Extensions
This is a fun demo/POC of using Clojure + Linux FUSE (Filesystem in Userspace).
Currently I have a sample that maps some RESTful API data to a local
file mount. This then allows the user to run all their native file
level commands (ls, grep, feh) on the directory.
I also have a working implementation of mounting a Postgres database as a file system.
Next up, may do the same for MySQL.
This requires lein:
After it is installed and 'lein' is in your $PATH, just run (in project root):
lein deps
Try this command, you'll be able to browse a directory sourced from the RESTful API from the response of images at: https://dog.ceo/api/breed/dane-great/images
This would be a great way to view/edit CRUD documents over other RESTful endpoints, or even to display database records for editing in a user's favorite editor.
mkdir /tmp/dog-pics && lein run dog /tmp/dog-pics
Then in another terminal:
cd /tmp/dog-pics
ls
cd dane
feh dane-0.jpg # Use your CLI image editor of choice
or if you prefer a more GUI based approach, just open your thumbnailer capable file explorer (or use these two small tools to do it):
sudo pacman -S raw-thumbnailer pcmanfm
cd /tpm/dog-pics
pcmanfm .
Create (or update) a ~/.ruserc file, by copying the repo template one from conf/default-rc.edn, then plugin your own database credentials.
Now, run it via:
mkdir /tmp/my-db ; lein run pg /tmp/my-db
