Hi all,

I have a manifest that look like this

case $provider {
'package' : {
package {'mypackage' :
ensure => latest,
}
}
'source' : {
exec {'install procedure' :
}
}

$test = get_test_path()

file {'myconf' :
content => templates('mod/myconf'),
}

Within mycon template I have a variable 'test' that depending if the
package was installed from source of from the package will have a different
path.
Issue is that the function get_test_path() seems to be done at compile
time, so the first time I run it will always result in an erroneous answer.
After a second run it will be fine.

Does any one can provide guidance on how I could make it work at the first
run ?

Thank you,

    *Specification* : my manifest look more like this

    class myclass ($provider = 'package') {
    case $provider {
    'package' : {
    package {'mypackage' :
    ensure => latest,
    }
    }
    'source' : {
    exec {'install procedure' :
    }
    }
    }

    define myclass::mydefine() {
    $test = get_test_path()

    file {'myconf' :
    content => templates('mod/myconf'),

    What you should do instead is set the path based on the value of
    $myclass::provider.

    if $myclass::provider == 'package' {

    You should set the path based on the value of $myclass::provider:

    if $myclass::provider == 'package' {
    test = '/path/a'
    }
    else {
    test = '/path/b'
    }

    Thanks, I don't know why I tried to make it hard when it could be simple.

    To answer the question posed by the thread subject, no, it is not possible
    to make puppet functions be evaluated by the puppet agent during catalog
    application. They are always evaluated by the master during catalog
    compilation.

    Any dynamic behavior you want to happen on the agent side must be performed
    by your resources. Often you don't actually need agent-side dynamism
    beyond what Puppet already provides, but when you do, you generally need
    either to use an Exec resource, or to write a custom provider for an
    existing resource type, or to write a whole custom type / provider pair.
