Basic string manipulation in puppet

[Aaron Nicoli]

Hi all,

Been searching the net for a few hours now.
I have a basic operation I wish to perform but, cannot find examples
close enough to what I'm after to implement it myself.

This is what I want to do:

$version = '10.2.0'

I want to manipulate the string to make a new var ($cutversion), equal
just 102.

For example in perl (since I know it):

$version = '10.2.0';
if ($version =~ /^(\d+)\.(\d+).*$/) {
$cutversion = $1 . $2;
}

Any help?

Thanks,
Aaron.

There are not that many string manipulating functions in puppet itself
but you can always build your own [1] or have a look at the puppet-std
[2]

However your problem can be solved with the build-in function regsubst
which can be found in the function reference [3]

This should work (while untested)

$cutversion = regsubst($version, '^(\d+)\.(\d+).*$', '\1\2')

Does this help?
