Ratpoison: Clipboard Stack

This is the second post about the Ratpoison window manager.

 How many times did you found your self keeping snippets of text in a text editor just so you can use them later because your clipboard will be overwrited with the new selection?

Here is a very neat solution using ratpoison: a clipboard stack.

Using xclip, a simple shell script and the appropriate ratpoison key bindings we could accomplish the following:

Note that C-t is the default Ratpoison escape sequence.



With C-t = the clipboard stack is displayed using ratmen so we can select the snippet we want to be the current one.



With C-t # a ratmen menu is displayed so we can perform operations on the stack such as:
  • Push: Push the current selection into the stack
  • Pop: Take the last snippet in the stack as the current selection (so we can paste it with Ctrl+v as usual)
  • Delete: Display the list of snippets in the stack so we can select one to delete it
  • Purge: Completely purge the content of the clipboard stack




We get this functionality using the ratpoison bindings:


    bind numbersign  exec clipboard_stack.sh menu
    bind equal  exec clipboard_stack.sh select


This snippet appears in my .ratpoisonrc file that you can read entirely here

Note that i've used key bindings that corresponds to the default ones that tmux uses for the same task.
 
So now we can push into the stack the selections we know we could use latter and select them from the list wen needed.

The script depends on ratmen , xclip
And you can get it from my Dotfiles

To try it out be sure to define your Ratpoison bindings referencing the right location of the script.
