With DSL configuration format we introduce support for computable values for properties. It is now possible to set value which is result of a computation, ie. concatenation of a strings or very simple mathematical expression. We currently support only following mathematical operations:
- add
- subtract
- multiply
- divide
Example of setting environment variable related path and computed timeout.
bean {
# setting path to `some-subdirectory` of user home directory
path = prop('user.home') + '/some-subdirectory/'
# setting timeout to 5 minutes (setting value in milliseconds)
timeout = 5L * 60 * 1000
# previously it would need to be configured in following way:
# timeout = 300000L
}
Warning
For properties which accepts lists it is not allowed to set value using computed values with comma separated values like value1,value2 wrapped in [], ie.
property = [ env('some-variable') + ',other-value' ]. It needs to be set in following way property = env('some-variable') + ',other-value'.
