#1393 — Easy way to read clipboard?

The Paste[] command will paste the current contents of the clipboard
into a cell.  In theory, one can then access the contents of a cell by
executing front-end commands in the kernel, but I'd prefer something
more direct.

Say that I want to set the variable Foo to the current contents of the
Clipboard, which holds the number 100.  I'd like to be able to execute
something like Foo = ReadClipboard[] and have Foo set to the integer
value 100.

Any suggestions?

You can obtain the clipboard in the form of a notebook expression:

NotebookGet[ClipboardNotebook[]]

This is a bit messy however, because in general, the contents of the 
clipboard under Mathematica, may contain several cells, including text 
cells, and formatting information. If you knew that the clipboard should 
only contain a certain type of thing - say a number, or an expression, 
you could write code to extract it from the notebook expression, but to 
make it robust, you would have to decide what to do with all the other 
things that might be in the clipboard - such as:

  foo[

NotebookGet[ClipboardNotebook[]]

is the basis for what you want. It will return a Notebook expression,
that may contain anything, so needs to be analyzed.

In the simplest case, where you assume that the clipboard contains
syntactically correct text, eg "100" then this will work...

foo = First[Cases[NotebookGet[ClipboardNotebook[]], Cell[text_,
___] :> ToExpression[text], Infinity]]

NotebookGet@ClipboardNotebook[]

or any other notebook manipulation commands on ClipboardNotebook[]
