## What it is
Almond is a Scala kernel for Jupyter, formerly known as jupyter-scala. It wraps the Ammonite Scala REPL with Jupyter integration, offering Spark support, plotting library integration, and libraries for writing custom Jupyter kernels in Scala.

## Use cases
- run Scala code in Jupyter notebooks
- use Spark from a Jupyter notebook
- get an interactive Scala REPL with dependency handling
- write custom Jupyter kernels in Scala
- plot data from Scala notebooks with plotly or Vegas
- try Scala in the browser or via Docker

## When to choose
- you want to do Scala-based data science or big data work in Jupyter
- you want Ammonite features like magic imports and pretty-printing in notebooks
- you need to prototype Spark jobs interactively
- you want to build a Jupyter kernel for another JVM language

## When to avoid
- you need a JVM-free environment since a JVM is required
- you only need Python notebooks
- you need a kernel for a non-JVM language without writing custom kernel code

## Facets
- artifact type: library
- maturity: active
- function: interpreter, sdk
- domain: data-science, programming-languages, big-data
- platform: jvm, cross-platform
- tags: scala, jupyter-kernel, repl, spark, ammonite, notebooks, docker
