I''ve got the following template.
<VirtualHost *:80>
DocumentRoot /web/<%= name %>
ServerName <%= name %>.example.com
<% unless server_alias.empty? %><%= server_alias %><% end %>
</VirtualHost>
At times I need to pass an empty variable.
vhosts { ahost:
document_root => "/var/www/html/",
server_alias => "",
}
The problem I''m trying to fix is to stop printing a new line when the
variable is empty. I know very little Ruby/erb but I''ve tried the
line above and an "if empty chomp" and
<% if server_alias.empty? %><%= server_alias -%><% else
%><%server_alias %><% end %>.
Anyone know how to stop the template from printing a blank line when a
variable is empty?
Thanks,
Kent

Try putting your conditional on multiple lines, with the -%> on the lines you don''t want to show up <% unless server_alias.empty? -%> <%= server_alias %> <% end -%> -Andrew On Feb 22, 2008, at 11:02 PM, Kenton Brede wrote:> On 22/02/2008, David Schmitt <david@schmitt.edv-bus.at> wrote: >> -----BEGIN PGP SIGNED MESSAGE----- >> Hash: SHA1 >> >> >> On Friday 22 February 2008, Kenton Brede wrote: >>> I''ve got the following template. >>> >>> <VirtualHost *:80> >>> DocumentRoot /web/<%= name %> >>> ServerName <%= name %>.example.com >>> <% unless server_alias.empty? %><%= server_alias %><% end %> >>> </VirtualHost> >>> >>> >>> At times I need to pass an empty variable. >>> >>> vhosts { ahost: >>> document_root => "/var/www/html/", >>> server_alias => "", >>> } >>> >>> The problem I''m trying to fix is to stop printing a new line when >>> the >>> variable is empty.
