[sage-devel] Using Eclipse as an IDE to edit / run Sage scripts

2017-04-17 Thread Maxie Schmidt 
Hello all. 

I'm interested in using Eclipse as an IDE around editing Sage files for 
Windows users who aren't experienced with a command line environment like 
ipython or the Sage shell. My interest in this is as part of a teaching and 
mentoring experience for mathematically-oriented users learning Python for 
the first time. I'm having some trouble motivating them to use Sage more 
frequently on Windows. 

I have found this link 
(https://groups.google.com/forum/#!topic/sage-support/YouA5r68wxc), but it 
still seems incomplete. Does anyone know of a good reference for using Sage 
from within Eclipse, or otherwise have any interest in this topic if I can 
put something together to get this all working? Any other suggestions or 
links to tips for getting these motivated users up and running with Sage 
besides the assignments I have prepared for them at 
https://github.com/maxieds/WXMLTilingsHOWTO/wiki would also be useful to me 
if you have them. 

Thanks. 

Maxie

That's not entirely true.  Have you tried Docker Toolbox?
https://www.docker.com/products/docker-toolbox

It works on Windows 7 and up and was the previous basis for my Windows
installer for Sage, and worked fine.

You can also try the Windows installer but it's currently at Sage 7.4
and is not "official" yet.

Why would any more browser windows need to be launched after one selects a 
sagenb notebook to convert?
I just don't get it.

 I get to the page listing the notebooks to convert, and then, if I 
 click on a notebook, I get a weird page asking for a password or a token.

 Password or token:
  Log in

 Token authentication is enabled. You need to open the notebook server 
 with its first-time login token in the URL, or enable a password in order 
 to gain access. The command:

 jupyter notebook list

 will show you the URLs of running servers with their tokens, which you 
 can copy and paste into your browser. For example:

 Currently running servers:http://localhost:/?token=c8de56fa... :: 
 /Users/you/notebooks

 Or you can paste just the token value into the password field on this 
 page.

 Cookies are required for authenticated access to notebooks.



 What I see above doesn't look as a valid URL, and then WTF is the token 
 I can paste instead?

 I tried c8de56fa, it didn't work. I tried clicking on the URL, it 
 brings me back to the page to choose

 the notebooks...

  Arrgh... Give me my console any time...

Well at least in your case it seems that chrome is detected and launched 
automatically, this is IMHO preferable to a commandline prompt.

 This should work on both Mac 10.11 and 10.12.   For bandwidth reasons I 
 would prefer if those with the ability simply upgrade and build from 
 scratch, but testing this app is also necessary.

 PLEASE TRY THIS and report back if you are at all interested in making 
 sure that Sage 8.0 doesn't come with nasty surprises for long-time sagenb 
 users.  Preliminary testing makes it seem as if we are okay, but it would 
 be very helpful to have feedback about better/more informative messages 
 for 
 end users.

 Note if you haven't downloaded a new one for a while: because it will 
 first have to patch some names to make sure all paths are correct, the 
 first launch will take a LONG time.

Perhaps it's a good idea to provide a prompt at this point, something like 
"Launch the browser? (yes/no)"

Hehe :) Paul was most probably referring to Nils, indeed! But it is legal 
if someone else takes initiatives if he/she is motivated and has some time 
(making a bit of noise around to avoid double work is good too). Moreover 
if what we produce is crap (probably, but that's normal), then experts will 
just say so, and we'll iterate to improve it.

well..  some people would argue that (for your own projects, for team work,

stuff to psychologists, but usually unexplored terrain for technical people 
like us. so keep it up!

In general you should read: http://doc.sagemath.org/html/en/developer/
But if you are familiar with git then you are some steps ahead. 
 
This week i don't have time to do it myself, but the task would be to 
create a ticket with the appropriate fields and description, and CC people 
(always checking for similar tickets).
