not displaying several html blocks if condition not met in ruby -


im trying restrict information being shown if data in not available.

in view.rb file, have this

<% if @content != nil %>  <div>    <h3>....</h3>     <% @content[0..3].each |something| %>        <li> .... <li>     <% end %>     <% @content[4..5].each |something| %>        <li> .... <li>     <% end %>     <% @content[5..11].each |something| %>        <li> .... <li>     <% end %>  <div> <% end %>

how ever if content nil, lines content[4..5].each |something| being run , throwing errors obvious reasons.

how multiple blocks of html , ruby code ignored if condition isn't being met?

if code <% content[4..5].each |something| %> executed, @content not nil, there no way ruby wrong that.

but, if empty array or blank string pass test. in order cover wide range of possible "nil-like" values (nil, empty, blank...) use:

<% unless @content.blank? %>

and let me know if helps.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
