Hello there,
Just wanted to know if class will be able to have parameters ?
Right now i use:
define resolver( $options =''rotate'', $nameserver,
$search='''',$domain='''',$sortlist=''''){
file{ ''/etc/resolv.conf'':
content =>
template(''/var/puppet/templates/System/etc/resolv.conf''),
owner => ''root'',
mode => 644,
alias => ''resolv.conf''
}
}
but it feel like a class to but each site as different nameservers so i
cannot use a class here. Also i am a bit loss in the erb template to say :
if $search is not '''' then print this, else print nothing,
right now it
allways print a DAM BLANK LINE ;-)
anyone knows how to prevent this ? Seems not possible if i look at the
doc but who knows with the fast paced enhancements of puppet :)

Ghislain

The <%= construct won''t print a newline after printing the evaluated value of the code inside the tags, so everything should be OK. If you''re doing something like <% print search %>, then (a) you shouldn''t be doing that, since you''ve got ''<%='', and (b) you can use ''-%>'' as the closing tag to suppress the trailing newline on empty lines. - Matt -- "For once, Microsoft wasn''t exaggerating when they named it the ''Jet Engine'' -- your data''s the seagull." -- Chris Adams

Also i am a bit loss in the erb > template to say :With the new scoped variables, you should be able to get close enough to what you want. E.g., you could have: class nameservice { $nameserver = "..." ... } class resolver { $nameserver = $nameservice::nameserver file { ''/etc/resolv.conf'': ... } } I expect that''s the closest we''re going to get to class parameters, and it''s probably as close as we need to get. -- I think that all good, right thinking people in this country are sick and tired of being told that all good, right thinking people in this country are fed up with being told that all good, right thinking people in this country are fed up with being sick and tired.

Yes, the ''-%>'' construct is what you want here: <% if search != '''' -%> search <%= search %> <% end -%> Check the ERB docs (or list archives) for an explanation of what ''-%>'' is doing for you there. - Matt -- If Alan Turing was alive today, the homosexuality would be OK but he''d be in trouble for codebreaking. -- Martin Bacon

I have reread the docs of erb: http://www.ruby-doc.org/stdlib/libdoc/erb/rdoc/ and i seee nowhere the -%> but i could have missed it. -- Cordialement, Ghislain _______________________________________________ Puppet-users mailing list Puppet-users@madstop.com https://mail.madstop.com/mailman/listinfo/puppet-users
