Notas sobre la instalación y uso de Scala.
Introducción
De acuerdo a la Wikipedia1,2, «Scala es un lenguaje de programación multi paradigma diseñado para expresar patrones comunes de programación en forma concisa, elegante y con tipos seguros. Integra sutilmente características de lenguajes funcionales y orientados a objetos. La implementación actual se ejecuta en la máquina virtual de Java«, y a primera vista parece similar a Java. Pero, conforme uno va explorando el lenguaje va uno advirtiendo las diferencias y, en ciertos aspectos, algunas similitudes con Python.
Instalación
Scala puede ser instalado en macOS vía Homebrew o a través de Coursier. De acuerdo a la opción seleccionada serán las acciones a seguir en la instalación.
Coursier
Coursier es el administrador de aplicaciones y artefactos de Scala, es el equivalente al pip de Python (aunque quizás sea mucho más apropiado compararlo con conda). Permite instalar aplicaciones de Scala y configurar el entorno de desarrollo. También puede descargar y almacenar en caché artefactos desde la web. Este debe ser instalado primero para proceder con la instalación de Scala. Ahora bien, Coursier mismo puede ser instalado via Homebrew o por via propia.
Vía propia
Conforme se indica en las páginas de la documentación de Scala sobre su instalación, para el caso de macOS uno debe seleccionar la instalación apropiada para un equipo Intel inside o Apple Silicon. Para el caso que aquí se registra, el comando usado fue:
$ cd $HOME/Downloads
$ curl -fL https://github.com/VirtusLab/coursier-m1/releases/latest/download/cs-aarch64-apple-darwin.gz | gzip -d > cs
% Total % Received % Xferd Average Speed Time Time Time Current

$
tras lo que se ejecutó:
$ chmod +x cs
$ ./cs setup
Checking if a JVM is installed
Found a JVM installed under /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home.
Checking if ~/Library/Application Support/Coursier/bin is in PATH
Should we add ~/Library/Application Support/Coursier/bin to your PATH via ~/.profile, ~/.bash_profile? [Y/n] Y
Checking if the standard Scala applications are installed
Installed ammonite
Installed cs
Installed coursier
Installed scala
Installed scalac
Installed scala-cli
Installed sbt
Installed sbtn
Installed scalafmt
$
Y, conviene revisar y anotar (lo destacado en negritas) la adición del script al profile de BASH.
# Scala
# >>> coursier install directory >>>
export PATH="$PATH:/Users/lalo/Library/Application Support/Coursier/bin"
# <<< coursier install directory <<<
Cerrar y abrir la sesón en Terminal para que se tomen los cambios y validar el resultado con:
$ scala --version
Scala code runner version: 1.5.4
Scala version (default): 3.6.2
Vía Homebrew
La instalación de Coursier a través de Homebrew es sencilla para el usuario (como podrá apreciar con el comando resaltado en negritas) pero, podrá observarse que es una tarea compleja para el administrador de paquetes (en la M1 todo esto tomó unos 15 minutos). En este ejemplo, Homebrew mismo identifica elementos que requieren ser actualizados antes y procede con ello. El punto donde inicia con la instalación de Coursier ha sido destacado en anaranjado para fácil identificación.
Hay que destacar lo siguiente:
- La actualización de paquetes y bibliotecas (formulae, taps, casks, etc., de acuerdo a la terminología de Homebrew), como puede leerse, puede sólo recurrir a la descarga de un binario (asumiendo que las referencias a blobs en las rutas impliquen esto), o llevar a cabo la recompilación desde el fuente. Esto suma varios minutos a todo este proceso de instalación.
- Similarmente, prodrá observarse en lo que respecta a la instalación de Coursier, varias compilaciones son llevadas a cabo.
% brew install coursier
==> Auto-updating Homebrew...
Adjust how often this is run with HOMEBREW_AUTO_UPDATE_SECS or disable with
HOMEBREW_NO_AUTO_UPDATE. Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

Desinstalación
De acuerdo a la opción seleccionada en la instalación, dependerá la forma en la que se lleve a cabo la desinstalación.
Coursier
Si la instalación se llevó a cabo mediante Coursier, es mediante Coursier que debe removerse. Los pasos a seguir para una desinstalación completa, es como se muestra a continuación:
$ cs uninstall --all
$ rm -r $HOME/Library/Application\ Support/Coursier
Finalmente, uno debe editar el .bash_profile (o el correspondiente archivo de arranque sel shell que se esté usando) y remover las líneas relacionadas con Scala, que pueden asemejarse por ejemplo a:
# Scala
export PATH="~/Library/Application Support/Coursier/bin":${PATH}
y reiniciar la sesión en Terminal, al menos.
