I hope I am going insane and the I'm not seeing the snake about to bite me...

How does one view the code in the demonstration projects that one can download from wolfram.com?

It seems like all of them come down as an 'Authoring Notebook' and I cannot always get the notebook to show a view of the code the author used.

Some of the notebooks have the cells 'docked' and you can view the code by double clicking the cell. Others, do not show the icon on the cell brackets to open their content, but the demonstration still functions.

It appears the code is definitely available by looking at the plain text of the file.

Are authors encouraged to obfuscate the code in their demonstrations? If not please direct me to the snake...

    $\begingroup$ Would you send a link to a particular demonstration, the code of which you have not been able to view? That way, we may see what you are experiencing. BTW, did you mouseover the places where the cell brackets normally appear. They may simply be hidden from view. $\endgroup$

Usually you can scroll down the cdf and find a "Download Source Code" button:

enter image description here

Clicking this button downloads another notebook where the code is explicitly visible.

On other browsers/platforms, you may see this:

screen cap

and if you click on (preview) you'll see this:

screen cap 2

although you can't copy this, because it's a GIF...

In order to see the code in the demonstration files, you simply click on the right bar of the section with the code, and select 'convert to input form'...

Then you can copy the entire code snippet and paste it into your new file, where it will then get syntax formatting & coloring.

  • $\begingroup$ You don't get to see code in a demo file, that is precisely the issue that is discussed. You do not get to see the cell structure to do a Right Click. $\endgroup$
