reference to local html-file with anchor (hashmark #) via \href

Question

I try to link to my local html-files with \href from hyperref package.

\documentclass{article}
\usepackage{hyperref}
\begin{document}
\href{run:relative_path/filename.html#anchor}{test}
\end{document}

It also works quite well only for the file itself. The anchor is cut off from the link in several pdf viewers such as Evince and Okular.

Interestingly, substituting run: by http://

\href{http://relative_path/filename.html#anchor}{hhh}

offers the anchor in Evince's and Okular's views.

Is there any way to get the run: to also provide the anchor?

Answer 1

If you modify the test to

\pdfcompresslevel=0
\pdfobjcompresslevel=0
\documentclass{article}
\usepackage{hyperref}
\begin{document}
\href{run:relative_path/filename.html#anchor}{test}


\href{http:relative_path2/filename.html#anchor2}{test}
\end{document}

Then you can look at the links hyperref is adding, which are:

/Subtype/Link/A<</F(relative_path/filename.html)/S/Launch/Win<</P(anchor)/F(relative_path/filename.html)
/Subtype/Link/A<</Type/Action/S/URI/URI(http:relative_path2/filename.html#anchor2)

Note that the # fragid syntax is really part of the http: URI scheme. The file: and PDF-specific run: schemes really expect a filename to pass to the local application to open a file on the local system and # is not part of the filename and so hyperref removes it.
