generate() function help

[Jakov Sosic]

Hi.

I want to run script which is distributed with my module, but the
problem is I have to then hardcode the path to the script in the
generate function call, for example:

generate("/etc/puppet/environments/${environment}/modules/mymodule/scripts/myscript")

But what If some other site uses other path to their modules, or doesn't
use environments at all? Is it possible somehow to detect the dir in
which the module is installed, so that I can use something like:


generate("$modulepath/scripts/myscript")

See stdlib:

HTH,

I've found that already. But I've decided to write my own function which
returns path to current module directory. If that doesn't succeed then
I'll use get_module_path.

Hm, I'm having problems with writing custom functions...

One question first - is it possible for custom function to generate some
files on a given path on puppet master? I've tried the following:

module Puppet::Parser::Functions
newfunction(:generate_host_keys, :type =>:rvalue) do |args|

Dir.mkdir("/tmp/something", 755)

end
end


But dir isn't created on puppet master on agent run...
