sagetex 3.0 is not python 3 compatible

Building Sage for python3 failed with

where is the source of sagetex.py ?

[chapoton]

humm... it seems that sagetex.py is generated somehow from sagetex.dtx

The sources are in ​https://github.com/dandrake/sagetex

[aapitzsch]

To fix this issue we probably have to wait for #22499.

The line causing the error is ​https://github.com/dandrake/sagetex/blob/master/py-and-sty.dtx#L964

[chapoton]

see ​https://github.com/dandrake/sagetex/pull/11/files

I have tried to write an email to Dan Drake, but I only managed to guess his email.

[chapoton]

I got an answer from Dan Drake, saying that he is willing to transfer the ownership of sagetex github repository to the sagemath group.

[chapoton]

sagetex is now part of the sagemath group in github:

​https://github.com/sagemath/sagetex

People from this group, please merge there the pull requests #5 and #11

sagetex is now part of the sagemath group in github:

​https://github.com/sagemath/sagetexhttps://github.com/sagemath/sagetex

People from this group, please merge there the pull requests #5 and #11

These have been merged, so should depend on #22499 (new package).

Sagetex does not run correctly when using Sage built with Python 3. I mean, sagetex now builds, but it does not work:

$ ./sage example.sagetex.sage 
  File "example.sagetex.sage.py", line 248
    print 'SageTeX paused on example.tex line 365'
                                                 ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print('SageTeX paused on example.tex line 365')?

All of the print statements need to be updated.

There is also an error when building sagetex with Python 3 which doesn't seem to stop the installation, but it breaks using it:

      File "/Users/palmieri/Desktop/Sage_stuff/sage_builds/PYTHON3/sage-8.4.beta6/local/lib/python3.6/site-packages/sagetex.py", line 181
        exec preparse(splitup[i][2]) in globals, locals
                    ^
    SyntaxError: invalid syntax

[chapoton]

I made a pull request on github, for the print problem only

[kcrisman]

There is now a new release of SageTeX at #27024 which hopefully fixes most of this.

[kcrisman]

Was this ever on #15530 or a related ticket, by the way?

[dimpase]

I think this is fixed by #27024

[dimpase]

Replying to kcrisman:

Was this ever on #15530 or a related ticket, by the way?

just added it there

[kcrisman]

Nice.

Presuming these are all correctly reviewed as either duplicate, invalid, or wontfix.
