ox-latex: Is \uline really right for underlining?

[James Harkins]

org-latex-text-markup-alist is a variable defined in `ox-latex.el'.
Its value is ((bold . "\\textbf{%s}")
 (code . verb)
 (italic . "\\emph{%s}")
 (strike-through . "\\sout{%s}")
 (underline . "\\uline{%s}")
 (verbatim . protectedtexttt))

underline . "\\uline{%s}" -- According to [1],

~~
\uline 
    Underlines text. Requires ulem package. See Formatting.
~~

Is "ulem" one of the LaTeX export default packages? I don't see that it is. 
If not, should org's default underlining command depend on a package that 
is not activated by default?

(There is no reference to -markup- anything in my .emacs, so I'm quite sure 
I haven't customized this variable.)

Yes, it is. See `org-latex-default-packages-alist'.

Ah... I must have customized that at some point.

Drifting off the topic slightly, to a related question. I have a feeling 
that something is a bit off in my installation. If I do M-x customize-group 
<ret> org-export <ret>, I have two links to "Org Export LaTeX":

Org Export LaTeX : Options for exporting Org-mode files to LaTeX.

Org Export LaTeX : Options for exporting Org-mode files to PDF, via LaTeX.

I think this is the source of some of my confusion about these export 
options.

Which one is current? Then I can figure out where the other one is coming 
from and make sure it doesn't get loaded.

Thanks,
hjh

And... I just found why I had customized it. It was because of
hyperref's (idiotic) default behavior of drawing red boxes around
links.

I'm not sure how "ulem" didn't make it into my customized setting.
Maybe "ulem" was added to the default packages list after I made the
customization.

What's the best way to handle that? I really want the "hidelinks"
option for hyperref to be used globally. But, customizing
org-latex-default-packages-alist means that I will miss updates to
that variable in future org versions.

Should I leave org-latex-default-packages-alist alone, and add my own
entry for hyperref into org-latex-packages-alist? (Would there be any
ill effect from having two \usepackage{hyperref} lines in the
preamble, with different options?)

I don’t know for certain if having two \usepackages would have bad
effects, but my vague feeling is that you will be fussed at by the
LaTeX compiler and/or the options specified in the two instances will
not compose in the desired way.

You probably want the \hypersetup command (q.v. in the hyperref manual).
You can add it to the ‘org-latex-classes’.  You probably want something
like the following, slightly modified from the default:

(("article"
  "\\documentclass[11pt]{article}
\[DEFAULT-PACKAGES]
\[PACKAGES]
\hypersetup{hidelinks=true} % <--- the important bit
\[EXTRA]"
("\\section{%s}" . "\\section*{%s}")
  ("\\subsection{%s}" . "\\subsection*{%s}")
  ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
  ("\\paragraph{%s}" . "\\paragraph*{%s}")
  ("\\subparagraph{%s}" . "\\subparagraph*{%s}")))

HTH,
