'substr' function

[Jonathan Gazeley]

Another dumb question, but I can't find what I'm looking for. Does
Puppet have a function that's equivalent to the substr() function in
Perl? I want to truncate arbitrary strings to 7 chars but I can't see
how to do this with any of the built-in functions or functions in stdlib.

e.g. substr('hello', 4) returns 'hell'

Thanks,
Jonathan

I assume that you can use the sprintf function (from Puppet core).

sprintf("%20.8s", "string test") #=> " string t”

Apparently it is also possible with regsubst, like this:

regsubst($hostname, '^(.{7})(.*)', '\1')
