[sage-support] Problem with sagetex and fancyhdr
Hi, I have been trying to use SageTeX in a document where I also use the
fancyhdr package, and I am not able to put Sage computations in the header
(or the footer). A minimal example follows.
\documentclass{article}
\usepackage{sagetex}
\usepackage{fancyhdr}
\begin{document}
\begin{sagesilent}
n = 1
\end{sagesilent}
\fancyhead[R]{$\sage{n}$}
\title
{$\sage{n}$}
\maketitle
\thispagestyle{fancy}
\end{document}
After pdflatex, and running sage on the .sagetex.sage file, I get the
following error:
Processing Sage code for test02.tex...
Code block (line 7) begin...end
Inline formula 0 (line 14)
Sage processing complete. Run LaTeX on test02.tex again.
Inline formula 1 (line 17)
Error in Sage code on line 17 of test02.tex! Traceback follows.
Traceback (most recent call last):
File "test02.sagetex.sage.py", line 24, in
_st_.inline(_sage_const_1 , latex(n))
File "/usr/lib/python2.7/dist-packages/sagetex.py", line 121, in inline
'}{{%\n' + s.rstrip() + '}{}{}{}{}}\n')
ValueError: I/O operation on closed file
Running Sage on test02.sage failed! Fix test02.tex and try again.
Traceback (most recent call last):
File "test02.sagetex.sage.py", line 26, in
_st_.goboom(_sage_const_17 )
File "/usr/lib/python2.7/dist-packages/sagetex.py", line 264, in goboom
os.remove(self.filename + '.sagetex.sout.tmp')
OSError: [Errno 2] No such file or directory: 'test02.sagetex.sout.tmp'
As you can see, "inline formula 0" was generated properly and the
processing ended there; that line (14) is the \maketitle. On the other
hand, inline formula 1 was not resolved because the file was already closed
(note the "Sage processing complete" before); the line 17 where it arose is
the \end{document}. After the second pdflatex, the Sage result appears
correctly in the title but "??" appears instead in the header, and I get
the:
LaTeX Warning: Reference `@sageinline1' on page 1 undefined on input line
17.
Any suggestions on how to combine these two packages is very welcome, or at
least an explanation of this behaviour (why did Sage think that there was
nothing else to do after formula 0???). I cannot think of a workaround,
other than avoiding fancyhdr and searching for smart LaTeX to be able to
put things into place.
Thanks!

Re: [sage-support] How to search a usage of a specific function?
Hello,
To show the description of a function, you can type the name of the
function followed by a question mark ("Mod?" in your case) and press
Enter. If you want to show the source of the function, you can do the
same thing with two question marks instead ("Mod??").
