New screen features available

[Michael Schroeder]

Hi Screen Users,

you probably wonder why the new version of screen is not already
available. Well, it got delayed a bit because of a couple of new
features I've added. The development version is available from
GNU savanna: 

cvs -z3 -d:pserver:address@hidden:/sources/screen co screen

Here are the new features:

- vertical split, complete with resizing

  ^A |   split vertically

  resize [-l] [-h] [-v] <amount>

    -l : resize is local to slice
    -h : resize horizontally
    -v : resize vertically

  amount: 10       resize to size 10
  amount: +10      make 10 bigger
  amount: -10      make 10 smaller
  amount: 10%      make it 10% of all
  amount: =        make all windows equal

- better resize code using weights

  the layout will stay in shape even after heavy resizing

- window groups

  currently a bit ugly to create:
      screen -t <name> //group
  creates a group named <name>

  a group is a subset of windows, ^Aw will only display the
  current group and next/prev will not leave the group.
  Use ^A" to list all windows of the current group (this also
  leaves to group, so that next/prev or a second ^A" will
  show the other windows.

- layouts

  A layout stores the current setup of the display, i.e. all the
  slices and the window assignments.

      layout save Desktop1

  will save the current setup under the name "Desktop1". If you
  detach and reattach later on, the layout will automatically 
  be restored. "Desktop1" will become the current layout.

      layout autosave off

  This turns the autosafe feature off. Layouts are automatically
  saved if autosave is on and the user detachs or switches to
  another layout.

      layout new Desktop2

  Create a new empty layout named "Desktop2".

      layout name "foo"

  Rename the current layout to "foo".

      layout next
      layout prev
      layout load "name"

  Load the next/prev layout / the layout named "name".

      layout attach :last
      layout attach "name"

  Set the layout used when somebody is attaching. Default is ":last",
  this is the layout that was current when the last detach was done.
  
  Besides the restoring of the screen on re-attach, layouts can be
  used to implement a kind of "virtual desktop" in screen. Say
  you put "layout save Desktop1" in your ~/.screenrc. If you
  need a new Desktop, do "^A:layout new Desktop2". You can then
  use "layout next" to switch between both layouts.

So, feedback welcome. You probably have a lot of suggestions and
enhancement requests. Sorry that development is a bit slow at
the moment due to not enough spare time...

Cheers,
  Michael.
