[LaTeX] Problem with Links in headers

[LaTeX] Problem with Links in headers

[Andreas Scherer]

[-- Attachment #1.1: Type: text/plain, Size: 848 bytes --]

What's wrong with the attached MWE? If I try to compile *taocp.md* with *pandoc 
taocp.md -o taocp.pdf*, I receive the error message from LaTeX: 

Error producing PDF.
! File ended while scanning use of \@writefile.
<inserted text>  
               \par  
l.49 \begin{document}


If I delete either non-empty input line, the compilation is successful and 
the links work in the PDF dile.

(*pandoc taocp.md -s -o taocp.html* works fine.)

Not sure.  The way to diagnose this is to use

pandoc -t latex -s

to generate a latex file, then build using pdflatex;
you may get more informative errors this way, and you
can inspect the intermediate tex and see if anything
looks wrong. (You may need to enlist a tex expert for
this.)  If something is wrong in pandoc's latex output,
it can be fixed, but we need to understand the problem
first.  Does anyone have ideas? The latex is produced
below:

\hypertarget{fascicle-1-for-section-1.3-mmix-orig}{%
\paragraph{\texorpdfstring{Fascicle 1 for Section 1.3:
\href{file:///opt/archive/Code\%20For\%20Books/TAoCP\%20(Knuth)/fasc1.ps.gz}{MMIX}
(\href{https://www-cs-faculty.stanford.edu/~knuth/fasc1.ps.gz}{orig})}{Fascicle 1 for Section 1.3: MMIX (orig)}}\label{fascicle-1-for-section-1.3-mmix-orig}}

\href{file:///opt/archive/Code\%20For\%20Books/TAoCP\%20(Knuth)/err1f1.ps.gz}{Errata
for Fascicle 1}
(\href{https://www-cs-faculty.stanford.edu/~knuth/err1f1.ps.gz}{orig}).

> pandoc -t latex -s

I've set up a git environment and inspected the diff's between 'master'
and 'header-line' and 'text-line', resp.

Branch 'text-line' shows that deleting the 'paragraph' line from
'taocp.md' simply removes the related parts from 'taocp.tex' and
'taocp.aux'. It takes a single run through pdflatex to get a complete
PDF file.

Branch 'header-line', however, shows one non-trivial difference in
'taocp.aux', i.e., the 'spaces' have non-escaped percent characters; see
attachment. Running pdflatex twice resolves all references.

It appears that the problem is caused by the space characters in the
'file:///' directory reference. If I replace them with, e.g., '-', the
original TeX code compiles fine. (However, I do _not_ want to rename the
directory structure.)

Trying to escape the spaces in 'taocp.md' fails with both '\ ' and '%20'.

I wonder how deleting the neighboring text line can satisfy pdflatex.

Re: [LaTeX] Problem with Links in headers

[Andreas Scherer]

Finally, I was able to rearrange the full MD document to compile it successfully into PDF and HTML. Moving all '#' sectioning commands one level up seems to satisfy pdflatex. Maybe the 'paragraph' level was too deep (although there were more such items, none followed by 'text').

The final result is in this gist: https://gist.github.com/ascherer/b10e9680436f61bb776adef2c0c353f7
Thanks. Case closed.
