Load Scala file into interpreter to use functions?
I have some Scala functions defined in a file, not in a class, and I would like to use them i开发者_如何学Cn the Scala interpreter. I know I can say scala filename.scala
to simply run the file and exit the interpreter, but I would like to run the file and then stay in the interpreter so I can do some testing. Can anyone tell me how to simply load a file into the interpreter so I can use the functions defined within it?
type :load /path/to/file
in Scala REPL.
You can get complete list of available commands by typing :help
On occasions, :paste
might be your better friend (than :load
). Here is an example on how to use :paste.
scala> :paste
// Entering paste mode (ctrl-D to finish)
if (true)
print("that was true")
else
print("false")
[Ctrl-D]
// Exiting paste mode, now interpreting.
that was true
One can also use :paste
to load a file using following command :paste [path]
scala> :paste ~/Desktop/repl_seeder.scala
Pasting file ~/Desktop/repl_seeder.scala...
defined object test1
scala> test1.main(Str)
my first scala program
Just reminder, put the complete path. I found problem in Linux by doing like this:
:load ~/fileName.scala
to get rid of error "That file does not exist" I did
:load /complete/path/fileName.scala
