notebook questions

[John Cremona]

Some questions about Sage cloud notebooks (i.e. .sagews):

1. Is it possible to download just the input? When I download a
worksheet I get lines like

73b7ed58-0f7f-46f8-b581-e5eb9eec4da9so︠

appearing all over the place and it is tedious to edit them out. I
thought of using the "toggle output" before downloading, but that
toggle button does nothing.

2. In old-style Sage notebooks it was possible to have blocks of
explanatory text between cells. The closest I found with sagews is to
have a block tagged with %md but the result looks stupid since the
output repeats the input. The result is certainly not good enough to
use as a demo.

3. There is a Help button at the top of a worksheet but all it does is
enter something like help() in the worksheet itself. What use is
that?

4. I tried to see if I could open up some help in a second tab, but
opening a new tab just creates a copy of the old tab which doesn't
seem useful.

Those are markers for the input and output cells - which doesn't answer your
question.

Use %hide also (own line, maybe first?), and/or use the code-folding arrows ihn
the left margin.

No. You could use `grep -v` to remove all the input/output cell
markers though. They are delimited by two unicode characters.

You can hide the input using the toggle to the left. Or you can do
%md(hide=True).

That is not what the button does for me.

When I click the help menu, I get a dropdown menu with numerous
options. When I click the help *button* I get sent to
https://github.com/sagemathinc/smc/wiki/sagews

Exactly what web browser and OS are you using?

I don't understand this question.

No.  You could use `grep -v` to remove all the input/output cell
markers though.  They are delimited by two unicode characters.

OK, that would be a little faster than using emacs as I did.  I  suggest that it might be useful as an option to download input cells (perhaps with text cells prefixed by comment symbols).
 
In case anyone wonders why I want to do that, it's because I am using a free SMC account and some of the computations I want to do are time-consuming -- and I have plenty of powerful computers which run Sage.

%md(hide=True).

Thanks, that's perfect.

 Exactly what web browser and OS are you using?

Firefox on Suse enterprise, and/or chrome on ubuntu (I forget which one I was using when I posted).

(1) There's a help button near the top right of the screen next to my name and "About", and with an icon looking like a doctor's bag (?).  When I right click on that to open in a new tab I just get a copy of the same tab I was on.  If I just click on it I get a dialogue box offering to post a support question.
 
(2) There's a Help button in the sagews screen next to Mode and under the green Run button.  That does opo up a little menu of options.  The first one "General Help" has the effect I said, to insert "help()" into the worksheet.  The  next one also inserts some command into the worksheet.  I was expecting to *see* some help!

I don't understand this question.

I tried to explain more above (when I right-clicked).

​What about the following idea: next to the "save" ​button, there is a download dropdown button. One option is "PDF", which basically does what printing is now … and another option is "Sage": this option would convert the sagews file to a plain ".sage" file, for those cells which are in sage mode. I guess that would solve what you try to do.

This is the buttonbar. It's main purpose is -- or rather will be -- to give you some shortcuts for frequently used commands.

The button you're looking for is highlighted in blue and above that bar. It's pointing to https://github.com/sagemathinc/smc/wiki/sagews

there isn't much more help than that.

Tabs are an area where the sagemathcloud development philosophy is in conflict with the modern browser paradigm.  I am frequently frustrated by sagemathcloud's lack of support for right-clicking and opening in a new tab, and usually work around it by opening multiple tabs in my browser first and then navigating to slightly different spots within the same project.  I would definitely do so if I wanted to paste specific code or messages from a project into the support message box (support messages happen to persist when you close them, but that's not an interface behavior I'd expect or trust).

Thanks, Harald!

Yes, that would be perfect. Perhaps also on the separate download
page, for each sagews file listed there could be optoins as to what
format the user wants.

You probably cannot believe that I did not see that -- but in my
defense, having 3 different buttons on the page all labelled "Help" is
a little confusing, though it is my fault for having noticed only 2 of
the 3, especially as the one I missed was the one which answered my
questions (almost)!
