almond

Edit

Multiple kernels

Several versions of almond can be installed side-by-side. This is useful e.g. to have kernels for several Scala versions, or to test newer / former almond versions.

To install several version of the kernel side-by-side, just ensure the different installed versions have different ids (required) and display names (recommended).

For example, let's install almond for the scala 2.12.7 version,

$ SCALA_VERSION=2.12.7 ALMOND_VERSION=0.2.3-SNAPSHOT
$ coursier bootstrap -r sonatype:snapshots \
    -r jitpack \
    -i user -I user:sh.almond:scala-kernel-api_$SCALA_VERSION:$ALMOND_VERSION \
    sh.almond:scala-kernel_$SCALA_VERSION:$ALMOND_VERSION \
    --sources --default=true \
    -o almond
$ ./almond --install
$ rm -f almond

This installs almond with the default kernel id, scala, and default display name, "Scala".

Now let's also install almond for scala 2.11.12,

$ SCALA_VERSION=2.11.12 ALMOND_VERSION=0.2.3-SNAPSHOT
$ coursier bootstrap -r sonatype:snapshots \
    -r jitpack \
    -i user -I user:sh.almond:scala-kernel-api_$SCALA_VERSION:$ALMOND_VERSION \
    sh.almond:scala-kernel_$SCALA_VERSION:$ALMOND_VERSION \
    --sources --default=true \
    -o almond-scala-2.11
$ ./almond-scala-2.11 --install --id scala211 --display-name "Scala (2.11)"
$ rm -f almond-scala-2.11

--id scala211 ensures this kernel is installed along side the former, in a directory with a different name.

--display-name "Scala (2.11)" ensures users can differentiate both kernels, with the latter appearing in front-ends under the name "Scala (2.11)".
