Meld

A minimal example of creating a (mostly) working FUSE filesystem using Clojure. NOTE: I have only tested this with OSX, and it assumes you have already installed libfuse.

Trying it out

Create an empty directory at /tmp/meld to serve as your mount point, put these files in a directory called meld, then:

uce vs lit-element

A very simple comparison table between these two libraries.

	uce	lit-element
version	1.11.9	2.4.0
license	ISC (simplified MIT)	BSD-3-Clause License
language	JS w/ TS definition	TS w/ JS transpilation
size ^{_{( brotli )}}	9437b ES5 / 6811b ES2015+	8634b ES5 / 6708b ES2015+

Spike

I looked into the state of GraalVM and Clojure and wrote some small work-related scripts.

GraalVM Build Tools

Downloaded GraalVM and set $GRAALVM_HOME
Found two main libraries for building GraalVM CLIs - https://github.com/luchiniatwork/cambada#packaging-as-a-native-image and https://github.com/taylorwood/clj.native-image (or https://github.com/taylorwood/lein-native-image for the lein equivalent). I chose clj.native-image as it seemed more focused on doing one thing well.
First tried its template example which was easy to follow.
Then added a graalvm build to one of our small cli tools
Found it to be pretty straightforward except for a stdout flushing issue that was trivial to fix
