how can I call ruby function basename in puppet

Question

I'd like to call function File.basename which is available in Ruby. Is it possible in puppet?

Something like:

$filename = basename($download_url)

Ruby functions are not directly available in Puppet, but you can use inline_template:

$filename = inline_template('<%= File.basename(download_url) %>')

Thanks! I still find puppet syntax quite confusing... it's not ruby :) – Tombart Mar 10 '13 at 16:22
No, you're thinking of Chef, Which Is Ruby. – Tom O'Connor Mar 10 '13 at 16:41
@TomO'Connor Not anymore, Chef 11 uses Erlang. – Gergo Erdosi Mar 10 '13 at 16:46
Eugh. That *is* sickening. – Tom O'Connor Mar 10 '13 at 16:48

meanwhile it is possible to use the puppetlabs-stdlib which provides a basename() function.

Returns the basename of a path (optionally stripping an extension).

basename('/path/to/a/file.ext') returns 'file.ext'
basename('relative/path/file.ext') returns 'file.ext'
basename('/path/to/a/file.ext', '.ext') returns 'file'

Yes, the function seems to be available since `puppetlabs-stdlib 4.6.0` – Tombart Sep 26 '16 at 21:36

No, you can not call arbitrary Ruby functions in a Puppet manifest, but you can do so in Puppet templates which use ERB. Have a look at the inline_template function, which might be useful for your use case.
