Here is how to invoke the function 'fqdn_rand(30)' in irb
irb > require 'puppet'
irb > scope => Puppet::Parser::Scope.new_for_test_harness('localhost')
irb>> scope.function_fqnrand([30])
=> "1"
That may not work if your function requires a fully configured system.
If you need that set the breakpoint inside your function, and then
invoke with
puppet apply - i.e. puppet apply -e 'notice fqdn_rand(30)'
A good approach is to start with an rspec test for your function, then
you can invoke that when you want to debug. Look at
spec/unit/parser/functions/fqdn_rand_spec.rb for an example how to test
a function.
Hope that helps

Hallo,
I'm developing a custom function that is exhibiting some odd behavior,
so I would like to debug it.
How do I load it in the ruby shell in a way that lets me execute it?
I have tried the steps on the documentation:
irb(main):001:0> require 'puppet'
=> true
irb(main):002:0> require 'phash2text.rb'
=> true
irb(main):003:0> Puppet::Parser::Functions.function(:hash2text)
=> "function_hash2text"
irb(main):004:0> function_hash2text
NameError: undefined local variable or method
`function_hash2text' for main:Object
from (irb):4
from :0
But how can I actually execute the function?
Thanks,
Andrea
