url compared to hyperref

url compared to hyperref

[Marko Schütz]

[-- Attachment #1.1: Type: text/plain, Size: 303 bytes --]

When using hyperref and displaying the resulting PDF in xpdf, I see
links that are active. 

I tried achieving the same with useURL, url and goto, but the
resulting links aren't active in xpdf. I have to use acroread to have
active links.

Is there a compelling reason for this behavior?

Thanks,

Marko

Re: url compared to hyperref

[Sanjoy Mahajan]

Here is an example that I put on the wiki (because I kept forgetting
how to do it and wanted one place to find it again, but I never can
find it quickly there anyway, so now it's in the list archives at
least):

\setupcolors[state=start]
\setupinteraction[state=start,color=middlered]
\useURL [garden][http://contextgarden.net][][Context garden]
\starttext
The \from[garden] is useful.
\stoptext

I just tested it on the live context and it works fine with an active
link in the pdf file.  But it didn't work in the 2006.10.05 beta (the
space in the "Context garden" caused problems).

Maybe your example didn't have \setupinteraction[state=start] ?

Quick test here works fine. Can you post a small example file?

below I attach a LaTeX and a ConTeXt version. In xpdf the LaTeX
version gives me the link that launches urlCommand, whereas the
ConTeXt version presents the url text, but does not make it a link. In
acroread both documents result in links, however they are presented
slightly different.

Thanks,

Marko

Add

\setupinteraction[state=start]

in the beginning of the file.

That is because acroread tries to guess the url from the text.

I tried your recommendation (see attached files), but did not obtain
the desired results.

Re: url compared to hyperref

[Sanjoy Mahajan]

Your demimed ConTeXt source:

==================================
\starttext
\useURL[imara-web-page][http://imara.csail.mit.edu][http://imara.csail.mit.edu]
An interesting project can be found at \url[imara-web-page].
\stoptext
==================================

(by the way, I find it easiest if example tex code is placed inline in
a message, unless it needs attaching due to strange character codes or
whitespace issues, in which case quoted-printable encoding makes it
easier to scan than base64 encoding does.)

>From an earlier message in this thread:

  Here is an example that I put on the wiki (because I kept forgetting
  how to do it and wanted one place to find it again, but I never can
  find it quickly there anyway, so now it's in the list archives at
  least):

  \setupcolors[state=start]
  \setupinteraction[state=start,color=middlered]
  \useURL [garden][http://contextgarden.net][][Context garden]
  \starttext
  The \from[garden] is useful.
  \stoptext

  I just tested it on the live context and it works fine with an active
  link in the pdf file.  But it didn't work in the 2006.10.05 beta (the
  space in the "Context garden" caused problems).

  Maybe your example didn't have \setupinteraction[state=start] ?

Which looks like one of the problems.  For the other, you need to
replace \url with \from, giving:

\setupinteraction[state=start]
\starttext
\useURL[imara-web-page][http://imara.csail.mit.edu][http://imara.csail.mit.edu]
An interesting project can be found at \from[imara-web-page].
\stoptext

which works fine here.  If you want colored links (green by default), add

  \setupcolors[state=start]

And to change the link color, use the color= option to \setupinteraction:

  \setupinteraction[state=start,color=middlered]

thank you very much: the \from did the trick!
