Move windows\015\012\015\012This snippet adds nine [[grabs]] to move windows on the fly to nine defined views.

Current view\015\012\015\012This snippet works similar to the previous, it adds tags based on the view names. When there is an untagged window (a window with the default tag only) it adds the name of the current view as tag, which effectively moves the window to the current view.\015\012\015\012<pre>{{hide}}<code class="ruby">\015\012on :start do\015\012 # Create missing tags\015\012 views = Subtlext::View.all.map { |v| v.name }\015\012 tags = Subtlext::Tag.all.map { |t| t.name }\015\012\015\012 views.each do |v|\015\012 unless(tags.include?(v))\015\012 t = Subtlext::Tag.new(v)\015\012 t.save\015\012 end\015\012 end\015\012end\015\012\015\012# Assign tags to clients\015\012on :client_create do |c|\015\012 view = Subtlext::View.current\015\012 tags = c.tags.map { |t| t.name }\015\012\015\012 # Add tag to view\015\012 view.tag(view.name) unless(view.tags.include?(view.name))\015\012\015\012 # Exclusive for clients with default tag only\015\012 if(tags.include?("default") and 1 == tags.size)\015\012 c.tags = [ view.name ]\015\012 end\015\012end\015\012</code></pre>\015\012\015\012h2. Scratchpad\015\012\015\012The scratchpad snippet is just a small hack of the tagging. Normally [[subtle]] doesn't allow to create a window without tags, so that it's never visible. This grab just creates a "urxvt":http://software.schmorp.de/pkg/rxvt-unicode.html, strips all [[tagging|tags]] and sets sticky. On the next press it just toggles sticky and blends the window in and out, like a scratchpad.\015\012\015\012<pre>{{hide}}<code class="ruby">grab "A-b" do\015\012 if((c = Subtlext::Client["scratch"]))\015\012 c.toggle_stick\015\012 c.focus\015\012 elsif((c = Subtlext::Subtle.spawn("urxvt -name scratch")))\015\012 c.tags = [] \015\012 c.flags = [ :stick ]\015\012 end\015\012end\015\012</code></pre>\015\012\015\012\015\012 end\015\012end\015\012</code></pre>\015\012\015\012
