Module: sage.server.notebook.worksheet
A Worksheet.
A worksheet is embedded in a webpage that is served by the Sage server. It is a linearly-ordered collections of numbered cells, where a cell is a single input/output block.
The worksheet module is responsible for running calculations in a worksheet, spawning Sage processes that do all of the actual work and are controlled via pexpect, and reporting on results of calculations. The state of the cells in a worksheet is stored on the filesystem (not in the notebook pickle sobj).

Module-level Functions
s) |
Return everything after the first whitespace in the string s. Returns the empty string if there is nothing after the first whitespace.
Input:
t) |
t) |
s) |
Input:
text) |
Input: a block of wiki-like marked up text Output:
text) |
text) |
text) |
Output: Everything in text up to the first {{{.
s) |
cell_id, completions) |
aString) |
Given a string s that defines an input block of code, if the first line begins in "sage:" (or "»>"), strip out all lines that don't begin in either "sage:" (or "»>") or "...", and remove all "sage:" (or "»>") and "..." from the beginning of the remaining lines.
TESTS:
sage: test1 = sage.server.notebook.worksheet.__internal_test1 sage: test1 == sage.server.notebook.worksheet.ignore_prompts_and_output(test1) True
sage: test2 = sage.server.notebook.worksheet.__internal_test2 sage: sage.server.notebook.worksheet.ignore_prompts_and_output(test2) '2 + 2\n'
server, ulimit) |
Set the module-scope variable _a_sage to an initialized sage server.
Input:
The _a_sage variable is initially set to None:
sage: sage.server.notebook.worksheet._a_sage
We call init_sage_prestart and now _a_sage is a Sage instance:
sage: sage.server.notebook.worksheet.init_sage_prestart(None,None) sage: sage.server.notebook.worksheet._a_sage Sage
server, ulimit) |
Return one copy of a Sage compute process that has initialization code run.
Input:
sage: S = sage.server.notebook.worksheet.initialized_sage(None,None) sage: S Sage
v) |
Return smallest nonnegative integer not in v.
server, ulimit) |
Return a Sage interface that has been initialized.
Input:
If the global variable multisession is true, each call to one_prestarted_sage returns a new Sage compute instance. Otherwise it always returns the same instance.
sage: sage.server.notebook.worksheet.one_prestarted_sage(None,None) Sage sage: sage.server.notebook.worksheet.multisession=False sage: sage.server.notebook.worksheet.one_prestarted_sage(None,None) is sage.server.notebook.worksheet._a_sage True sage: sage.server.notebook.worksheet.multisession=True
s) |
The point of this function is to allow for searches like this:
"ws 7" foo bar Modular '"the" end'
i.e., where search terms can be in quotes and the different quote types can be mixed.
Input:
name, owner) |
Return the relative directory name of this worksheet with given name and owner.
Input:
sage: sage.server.notebook.worksheet.worksheet_filename('Example worksheet 3', 'sage10') 'sage10/Example_worksheet_3' sage: sage.server.notebook.worksheet.worksheet_filename('Example#%\&! work\sheet 3', 'sage10') 'sage10/Example_____work_sheet_3'
Class: Worksheet
self, name, dirname, notebook_worksheet_directory, system, owner, [docbrowser=False], [pretty_print=False], [auto_publish=False]) |
Create and initialize a new worksheet.

Input: search is a string that describes a search query, i.e., a space-separated collections of words.
Output: True if the search is satisfied by self, i.e., all the words appear in the text version of self.
self, user) |
Set his worksheet to be active for the given user.
Input:
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('Active Test', 'admin') sage: W.move_to_archive('admin') sage: W.is_active('admin') False sage: W.set_active('admin') sage: W.is_active('admin') True
self) |
Sets the worksheet to be published automatically when the worksheet is saved if the worksheet isn't already set to this otherwise it is set not to.
self, v) |
Set the list of collaborators to those listed in the list v of strings.
Input:
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: nb.add_user('sage','sage','sage@sagemath.org',force=True) sage: nb.add_user('hilbert','sage','sage@sagemath.org',force=True) sage: W = nb.create_new_worksheet('test1', 'admin') sage: W.set_collaborators(['sage', 'admin', 'hilbert', 'sage'])
Note that repeats are not added multiple times and admin - the owner - isn't added:
sage: W.collaborators() ['hilbert', 'sage']
self, filename) |
Set the worksheet filename (actually directory).
Input:
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('A Test Worksheet', 'admin') sage: W.filename() 'admin/0' sage: W.set_filename('admin/10') sage: W.filename() 'admin/10'

Set this worksheet filename (actually directory) by getting
the owner from the pre-stored owner via self.owner()
.
Input:
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('A Test Worksheet', 'admin') sage: W.filename() 'admin/0' sage: W.set_filename_without_owner('5') sage: W.filename() 'admin/5'

We create a worksheet and change the name:
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('A Test Worksheet', 'admin') sage: W.set_name('A renamed worksheet') sage: W.name() 'A renamed worksheet'
self, [check=false]) |
Set whether or not output should be pretty printed by default.
Input:
NOTE: The reason the input is a string and lower case instead of a Python bool is because this gets called indirectory from javascript. (And, Jason Grout wrote this and didn't realize how unpythonic this design is - it should be redone to use True/False.)
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('A Test Worksheet', 'admin') sage: W.set_pretty_print('false') sage: W.pretty_print() False sage: W.set_pretty_print('true') sage: W.pretty_print() True

sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('Publish Test', 'admin') sage: W.set_user_view('admin', sage.server.notebook.worksheet.ARCHIVED) sage: W.user_view('admin') == sage.server.notebook.worksheet.ARCHIVED True
self, W) |
Set the worksheet that was published to get self to W.
Input:
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('Publish Test', 'admin') sage: P = nb.publish_worksheet(W, 'admin') sage: P.worksheet_that_was_published() is W True
We fake things and make it look like P published itself:
sage: P.set_worksheet_that_was_published(P) sage: P.worksheet_that_was_published() is P True
self) |
Return the math software system in which by default all input to the notebook is evaluated.
Output: string
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('A Test Worksheet', 'admin') sage: W.system() 'sage' sage: W.set_system('mathematica') sage: W.system() 'mathematica'
self, user) |
Return True if the user with given name is allowed to edit this worksheet.
Input:
We create a notebook with one worksheet and two users.
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: nb.add_user('sage','sage','sage@sagemath.org',force=True) sage: nb.add_user('william', 'william', 'wstein@sagemath.org', force=True) sage: W = nb.create_new_worksheet('Test', 'sage') sage: W.user_can_edit('sage') True
At first the user 'william' can't edit this worksheet:
sage: W.user_can_edit('william') False
After adding 'william' as a collaborator he can edit the worksheet.
sage: W.add_collaborator('william') sage: W.user_can_edit('william') True
Clean up:
sage: nb.delete()
self, user) |
Return the view that the given user has of this worksheet. If the user currently doesn't have a view set it to ACTIVE and return ACTIVE.
Input:
We create a new worksheet and get the view, which is ACTIVE:
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('Publish Test', 'admin') sage: W.user_view('admin') 1 sage: sage.server.notebook.worksheet.ACTIVE 1
Now for the admin user we move W to the archive:
sage: W.move_to_archive('admin')
The view is now archive.
sage: W.user_view('admin') 0 sage: sage.server.notebook.worksheet.ARCHIVED 0
For any other random viewer the view is set by default to ACTIVE.
sage: W.user_view('foo') 1
self, user, x) |
Return True if the user view of user is x.
Input:
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('Publish Test', 'admin') sage: W.user_view_is('admin', sage.server.notebook.worksheet.ARCHIVED) False sage: W.user_view_is('admin', sage.server.notebook.worksheet.ACTIVE) True
self) |
Return list of viewers of this worksheet.
Output:
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: nb.add_user('sage','sage','sage@sagemath.org',force=True) sage: nb.add_user('hilbert','sage','sage@sagemath.org',force=True) sage: W = nb.create_new_worksheet('test1', 'admin') sage: W.add_viewer('hilbert') sage: W.viewers() ['hilbert'] sage: W.add_viewer('sage') sage: W.viewers() ['hilbert', 'sage']
self, username, threshold) |
Check to see if another user besides username was the last to edit this worksheet during the last threshold seconds. If so, return True and that user name. If not, return False.
Input:
self) |
Return the worksheet that was published to get this worksheet, if this worksheet was published. Otherwise just return this worksheet.
Output: Worksheet
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('Publish Test', 'admin') sage: W.worksheet_that_was_published() is W True
sage: S = nb.publish_worksheet(W, 'admin') sage: S.worksheet_that_was_published() is S False sage: S.worksheet_that_was_published() is W True

self, other) |
We compare two worksheets.
Input:
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W2 = nb.create_new_worksheet('test2', 'admin') sage: W1 = nb.create_new_worksheet('test1', 'admin') sage: cmp(W1, W2) 1 sage: cmp(W2, W1) -1
self) |
The getstate method makes sure that the self.__cells dictionary is not saved in the pickle since it could be huge.
Output: a dictionary; same as self.__dict__ but with some fields deleted.
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('Test Edit Save', 'admin') sage: v = W.__getstate__().keys(); v.sort(); v ['_Worksheet__autopublish', '_Worksheet__collaborators', '_Worksheet__comp_is_running', '_Worksheet__dir', '_Worksheet__docbrowser', '_Worksheet__filename', '_Worksheet__name', '_Worksheet__next_id', '_Worksheet__owner', '_Worksheet__pretty_print', '_Worksheet__queue', '_Worksheet__saved_by_info', '_Worksheet__system', '_Worksheet__viewers']
self) |
Return the number of cells in this worksheet.
Output: int

self) |
Return string representation of this worksheet, which is simply the string representation of the underlying list of cells.
Output: string
sage: nb = sage.server.notebook.notebook.Notebook(tmp_dir()) sage: W = nb.create_new_worksheet('test1', 'admin') sage: W.__repr__() '[Cell 0; in=, out=]' sage: W.edit_save('Sage {{{ 2+3 /// 5 }}} {{{id=10| 2+8 /// 10 }}}') sage: W.__repr__() '[Cell 0; in=2+3, out=5, Cell 10; in=2+8, out=10]'
