You mainly asked about property settings, this goes a little beyond that to consider loading a definitions file as well—and isn't much help for Windows—but I thought I'd share in case it's useful:
I've resorted to using a wrapper script saved as ~/bin/scala
, to set config properties and load some utility functions:
#!/bin/sh
# The scala REPL doesn't have any config file, so this wrapper serves to set
# some property values and load an init file of utilities when run without
# arguments to enter REPL mode.
#
# If there are arguments, just assume we're running a .scala file in script
# mode, a class or jar, etc., and execute normally.
SCALA=${SCALA:-/usr/local/bin/scala}
if [ "$#" -eq 0 ] && [ -r ~/.config/scala/replinit.scala ]; then
exec "$SCALA" -i ~/.config/scala/replinit.scala -Dscala.color
else
exec "$SCALA" "$@"
fi
If you sometimes use Ammonite REPL, as another answer suggests, the utility definitions can be shared by load
ing them from ~/.ammonite/predef.scala
:
try load.exec(ammonite.ops.home/".config"/'scala/"replinit.scala")
catch { case _: Exception => println("=== replrc not loaded! ===") }
I'm not sure about a way to load the init file for sbt console
automatically, though—Seth Tisue's comment about the initialize
setting is helpful for properties, but using a :load
command in a value for initialCommands in console
doesn't appear to work.
