How to find if computation is in a notebook or sage prompt ?

asked 2011-02-17 00:37:39 -0500

  • Example of what is needed in sage prompt:

    sage: is_sageprompt()


  • Example of what is needed in a notebook:

In an input cell: is_sagenotebook()

The output cell: True

Can you let us know how this would be useful? One of the things we like to do in Sage is make sure there is *not* a difference, so one can use either method, though things like @interact keep this from being 100% true.

I would like pretty print some results in both notebook and sage prompt. The comand html('

Big Table

') works fine in notebook but not in sage prompt. I will use html(...) in notebook and "print" in sage prompt.

Then using this flag should work fine.

There is an env variable of sorts called EMBEDDED_MODE, I think, which is used internally to tell whether one is in the notebook.

| Sage Version 4.6.2.alpha1, Release Date: 2011-01-20                |
| Type notebook() for the GUI, and license() for information.        |
*                                                                    *
* Warning: this is a prerelease version, and it may be unstable.     *
*                                                                    *
Loading Sage library. Current Mercurial branch is: plotpatches
sage: sage.plot.plot.EMBEDDED_MODE

But in the notebook this will give True.

Nice! It seems to me the natural place for some flag like that would be in notebook.*, which is where I looked for it.
