- Can I write more complex expressions in an interpolation? Can I do
something like "The sum is ${$a + $b}", and if that is the case, is it
possible to have any expression interpolated (including nested strings
with interpolation)?
Nope! Thanks for reminding me about this, I remember trying to make
Puppet do this and being disappointed.
I just tested on puppet 2.7.14...
puppet apply -e '$x = 1 $y =2 $b="x${$x+$y}x" notice($b)'
notice: Scope(Class[main]): x3x
notice: Finished catalog run in 0.01 seconds
And
puppet apply -e '$x = 1 $y =2 $b="x${"abc${$x+$y}abc"}x" notice($b)'
notice: Scope(Class[main]): xabc3abcx
notice: Finished catalog run in 0.01 seconds
So - seems to work just fine - at least simple, complex things :)
