Suppose I have a long string and I copy it to the clipboard:

s = "1234567890123456789012345678901234567890123456789012345678901234567890123456789012345";
CopyToClipboard[s]

When I paste the clipboard contents into a text editor I get that string all on a single line.

But when I use

CopyToClipboard[{s}]

I get

{"12345678901234567890123456789012345678901234567890123456789012345678\
90123456789012345"}

How can I avoid the line splitting? I see Options and Streams and TotalWidth in the documentation but I can't make heads or tails of any of it.

(You might wonder why I'm using {s} rather than just s: That seems to be the only way I can get a CDF document to copy anything to the clipboard.)

  • $\begingroup$ Or CopyToClipboard[InputForm@{s}] it depends of what do you want for quotes... $\endgroup$

  • $\begingroup$ @unlikely. Thank you! CopyToClipboard[ToString@{s}] does the trick. And CopyToClipboard["{" <> s <> "}"] does not produce any output to the clipboard in a CDF document. It seems (to me) that in a CDF document only lists can be copied to the clipboard. That leaves the dangling curly brackets to deal with but that's a different question and not so critical for my needs. If you write-up your first comment as an answer I'll gladly accept it. $\endgroup$

    $\begingroup$ In the 10.1.0 Front End this works: SetOptions[$FrontEndSession, {"PageWidth" -> 1000, "ExportTypesetOptions" -> {"PageWidth" -> 1000}}]. I have no idea how this relates to CDF. $\endgroup$

Converting a comment to an answer, in the 10.1.0 Front End this works: 

SetOptions[$FrontEndSession,
  {"PageWidth" -> 1000, "ExportTypesetOptions" -> {"PageWidth" -> 1000}}]

I do not use CDF so I do not know how this relates.

I found that I needed to set both options shown or the copy would still wrap. The value 1000 was purely arbitrary; Infinity may suit your needs better.
