Installing Almond (Jupyter Scala) kernel

Scala Kernel Instructions for MacOS

Note: These instructions are over 3 years old. Please consult the Scala docs and the Almond docs for up-to-date instructions.

1. Download Scala https://www.scala-lang.org/download/

   • check Java version (java -version)
   • Install Scala sbt brew install sbt@1

     You can use $SBT_OPTS to pass additional JVM options to sbt.
     Project specific options should be placed in .sbtopts in the root of your project.
     Global settings should be placed in /usr/local/etc/sbtopts
     

2. Install coursier

   brew install --HEAD coursier/formulas/coursier

3. Install almond

   • git clone https://github.com/willingc/almond.git

   • edit project/plugin.sbt

     • add addSbtPlugin("io.get-coursier" % "sbt-coursier" % "1.1.0-SNAPSHOT")

   • bootstrap install

     coursier bootstrap \
     →     -i user -I user:sh.almond:scala-kernel-api_$SCALA_VERSION:$ALMOND_VERSION \
     →     sh.almond:scala-kernel_$SCALA_VERSION:$ALMOND_VERSION \
     →     -o almond
     

   • ./almond --install

Question, is step three correct? I think the file is named plugins.sbt not plugin.sbt. Please verify whether the doc above has a typo or which I need both files.

Also wrt step 3, where should the line be added in that file? beginning or end or doesn't matter.
Here is what was already in the file after I cloned the repo

addSbtPlugin("com.geirsson" % "sbt-ci-release" % "1.2.2")
addSbtCoursier

Also, wrt step 3, the bootstrap install step doesn't say where to run the courier command? home directory? or inside the cloned repo.

@jimka2001 I would consult the Almond docs. This gist is over 3 years old, and I haven't used Scala in about the same time. Good luck!
