remove sagenb developer docs from the developer manual and tutorials, remove sws stuff

[Dima Pasechnik]

​https://doc.sagemath.org/html/en/developer/index.html#sage-notebook-developer-guide is still present, and should be removed, as we don't have sagenb any more.

Also, remove various sws2bla and bla2sws scripts and related docs

more traces of sws

[John Palmieri]

For the tutorial, I would suggest removing the section _section_notebook completely, and making a change like this:

src/doc/en/tutorial/introduction.rst

@@ -103 +103 @@
 You can use Sage in several ways.
 
 
--  **Notebook graphical interface:** see the section on the
-   Notebook in the reference manual and :ref:`section-notebook` below,
+-  **Notebook graphical interface:** run `sage -n jupyter`; see 
+   `the Jupyter documentation on-line <https://jupyter-notebook.readthedocs.io/en/latest/notebook.html>`_,
 
 -  **Interactive command line:** see :ref:`chapter-interactive_shell`,
 

Unfortunately I don't know to write that in the various languages we offer. If you don't want to do this, I would at least suggest removing "the section on the Notebook in the reference manual", since I don't think that such a section exists.

[Dima Pasechnik]

there are still leftovers of sws format stuff in docs.

[Dima Pasechnik]

OK, I think I managed en/ru/de[plattdeutsch:-)] and for fr/es/pt/jp I inserted a bit of English (pardon...).

Could someone versed enough in these please fix these languages.

The remaining challende is to fix Sage Mac app, which refers to sws files in menus etc. For this we need someone who knows enough Xcode IDE, I gather.

Removal of binaries is best done on top of #21559

Spanish done, thanks to Reimundo.

[David Coudert]

This could be better for french in src/doc/fr/tutorial/introduction.rst

--  **Interface graphique (« notebook ») :** démarrer `sage -n jupyter`; lire 
-   `Jupyter documentation on-line <https://jupyter-notebook.readthedocs.io/en/latest/notebook.html>`_ ;
+-  **Interface graphique (« notebook ») :** démarrer `sage -n jupyter`; lire la
+   `documentation en ligne de Jupyter <https://jupyter-notebook.readthedocs.io/en/latest/notebook.html>`_ ;

But it's true that the current form clearly indicates that the on-line documentation of jupyter is in english.

[Dima Pasechnik]

I'm surprised in fact that Jupyther has no localised docs, but I can't find any, at least nothing official.

[David Coudert]

At least it has a documentation, while today many software have no docs at all (and don't expect proper comments in the code).

rebased over the latest copy of #21559 (and latest 9.2.beta4)

[Dima Pasechnik]

macOS app to be fixed on #30099

[John Palmieri]

When I look at the branch on trac, the last entry is a new file "t", containing

if test x`locale -a | grep C\.UTF-8` != x; then
 export LC_ALL=C.UTF-8;
else
 export LC_ALL=C;
fi

echo $LC_ALL

Is that supposed to be there?

Otherwise, I think we should merge this and fix the remaining languages later.

[John Palmieri]

Good, thanks.

[Samuel Lelièvre]

Sorry I didn't pay attention to this ticket in the past month and only realise now...

I would have suggested to keep the "sws to other formats" converters for a year.

This would give time to migrate legacy worksheets, matching our one-year deprecation period.

Of course, people can always download Sage 9.1, or find it on CoCalc... for a while.

[Dima Pasechnik]

converters are still there.

Only the already broken sws<->rst converters are removed here.
