Description (last modified by was)

This came up on the mailing list: it would be nice if sage -t worksheet.sws worked.

Also, it would be nice to have a button when using notebook that would launch sage -t on it and display the result.

Separate, but also nice, would be "worksheet-ify" command that took a series of doctests and made a nice worksheet out of it.

(NOTE -- I rethought this in the last paragraph below, but didn't delete the stuff above, in case it is useful still.)

How I would implement this:

 sage -t foo.sws


  1. extract foo.sws into a temporary directory. Try to use builtin library calls instead of calling tar on the command line, if possible. Note that foo.sws is a .tar.bz2
  1. Ignore everything not in {{}}'s. I'm using {{ instead of triple {'s to avoid trac's wiki preformat mode.
  1. Create a file For each chunk of code
    input lines
    output lines

insert into the file lines:

sage: sage.server.notebook.cell.eval_for_testing(r"""input lines
input lines...""")
output lines

since I think how the notebook works is best simulated by using the sage0 pexpect interface (that's what the notebook really uses).

  1. Doctest using sage -t and let normal doctest report the results. Possibly postprocess the print sage0.eval(r""" wrapper crap out of the result.

The above plan has the advantage that it reduces things to the existing python doctest framework instead of trying to write another doctest system. One disadvantage is that using sage0 means that two Python processes are spawned instead of 1.

The function sage.server.notebook.cell.eval_for_testing has not been written. It would make a blank directory, call sage0.eval -- just like the notebook does -- then apply all transformations the notebook does on output.

Actually, writing the above makes me think that this problem is harder than I thought when I started writing this comment! The problem is the output is potentially very complicated, since it can be a bunch of sagexxx.png files, html, etc. Maybe a better approach is to completely use the notebook codebase -- as is done in all the notebook doctesting -- to run a *copy* of the whole worksheet (a sort of evaluate all) -- then simply compare the original's output to the copy's.

After #12415, this just needs to add a parser for .sws files in sage.doctest.sources analogous to PythonSource, RestSource and TexSource.

  • Milestone changed from sage-feature to sage-duplicate/invalid/wontfix
  • Status changed from new to needs_review

With no progress on it and with sws planned for retirement together with SageNB, I think we should close it.

yes, let us close that
