Links in PDF

[ramnathv]

I saw a couple of students raise the issue of links not being clickable in the pdf version. I am investigating how to modify the print css so that links are clickable (I am not even sure if it is possible).

In the mean-time a quick fix is to include the following css in assets/css/custom.css

@media print {
  a:after {
   content: " (" attr(href) ")";
   font-size: 10px;
  }
}

This would print the link along with the title in the pdf print version so that users can copy-paste the link. This is sub-optimal, but a viable solution at this stage.

Here is some code to update all your custom.css files in one go. You need to run this from the root directory.

files_ = list.files(pattern = 'custom.css', recursive = TRUE)
extra_css = '@media print {
  a:after {
   content: " (" attr(href) ")";
   font-size: 10px;
  }
}'

lapply(files_, function(f){
  content = slidify:::read_file(f, warn = F)
  content = paste(content, extra_css, collapse = '\n')
  cat(content, file = f)
})

The pdf files will have to be printed manually from chrome. I am investigating an automated routed to achieve that and will keep you posted if I succeed :-)

A simpler solution is to print the slides using Safari which retains the html links.

I'll try to fix this this afternoon and resubmit the pdf files. Hopefully that will fix the problem. Thanks for all your support during this process!

Jeff, the links on Coursera (served from cloudfront) have not updated. Just wanted to give you a heads up.
