I have a hash of key:value pairs that is to be printed. All of the keys are Strings of varying length, and for readability, I would like the output to be formatted in two columns.
<% @foo.each do |bar| %>
<%= bar['key'] %> <%= bar['value'] %>
<% end %>
Is it possible to accomplish this, either through a setting in my recipe or on the template itself?
On the non-printing tags (i.e. <% %>
) you can use -
to trim whitespace. <%-
will remove whitespace before the tag and -%>
will remove whitespace after the tag. If you do <%- @foo.each do |bar| -%>
and <%- end -%>
it will remove the blank lines entirely. How you do the padding for the printing lines, look at the Ruby methods ljust
and rjust
.
