In Scala, is it possible to write a script which refers to another script
I am currently looking at using Scala scripts to control the life-cycle of a MySQL database instead of using MS-DOS scripts (I am on Windows XP).
I want to have a configuration script which only holds configuration information, and 1 or more management scripts which use the configuration information to perform various operations such as start, stop, show status, etc .....
Is it possible to write a Scala script which includes/imports/references another Scala script?
I had a look at the -开发者_JAVA百科i option of the scala interpreter, but this launches an interactive session which is not what I want.
According to Scala man, script pre-loading only works for interactive mode.
As a workaround, you can exit the interactive mode after running the script. Here's the code of child.bat
(script that includes another generic one):
::#!
@echo off
call scala -i genetic.bat %0
goto :eof
::!#
def childFunc="child"
println(geneticFunc)
println(childFunc)
exit;
genericFunc
is defined at genetic.bat
The output of child.bat
:
>child.bat
Loading genetic.bat...
...
geneticFunc: java.lang.String
Loading child.bat...
...
childFunc: java.lang.String
generic
child
I'd use Process and call the other Scala script just like any other command.
One option would be to have a script which concatenates two files together and then launches it, something like:
@echo off
type config.scala > temp.scala
type code.scala >> temp.scala
scala temp.scala
del temp.scala
or similar. Then you keep the two seperate as you wished.
