how to (automatically) convert many .sws to .ipynb?

edit

For a folder with a bunch of .sws files and taking advantage of what has been said above, one can make a bash shell script command, something like:

for file in *sws; do sage -sws2rst "$file" "${file%.sws}.rst"; done

and the same for rst to ipynb

for file in *rst; do sage -rst2ipynb "$file" "${file%.rst}.ipynb"; done

These is done in the folder with many .sws files.

In macOS 10.12.6 Beta with SageMath version 7.6, Release Date: 2017-03-25 the shell script worked. The conversion is note perfect!

You can transform .sws into .rst with the command:

sage -sws2rst file.sws file.rst

Then, once trac ticket 21514 will be merged (hopefully in the next official version of Sage), you will be able to transform .rst into .ipynb with

    sage -rst2ipynb file.rst file.ipynb

Then you should be able to loop with the find shell command.

I wrote a script to take a download_worksheets.zip file from the current directory and write the converted .ipynb files to the directory converted. It also prints the name of the temporary directory containing sagenb storage heirarchy. This directory needs to be deleted after the process is over. It would be nice if the script can be suitably modified to work with command line arguments and possibly with a directory of files rather than a .zip file.

import os
import zipfile
oldwd=os.getcwd()
zip_file=zipfile.ZipFile(oldwd+'/download_worksheets.zip')
ipd=oldwd+'/converted'
os.mkdir(ipd)

import tempfile
wd=tempfile.mkdtemp()
os.chdir(wd)
print(wd)

from sagenb.notebook.notebook import load_notebook
from sagenb_export.actions import action_print, action_convert_ipynb
from sagenb_export.sagenb_reader import NotebookSageNB

nb=load_notebook(wd+'/sage_notebook')
nb.create_default_users('totallysecret')

for fl in zip_file.namelist():
    zip_file.extract(fl)
    ws = nb.import_worksheet(fl,'admin')
    os.unlink(fl)

nb.save()

for fl in zip_file.namelist():
    nfl=fl[:-4]
    sagenb=NotebookSageNB.find(wd,nfl)
    action_convert_ipynb(sagenb,ipd+'/'+nfl+'.ipynb')
