Re: Ioslides inside rmarkdown has no license

Hi Andreas,

I took over the maintenance of the rmarkdown package only recently, and I was not the person who introduced ioslides to the rmarkdown package. That said, it does seem that the ioslides library's license is missing and unclear. I'm not its author, so I cannot add a license to it. I guess it will be difficult to get in touch with its original authors.

I don't quite see the benefits of making a Debian package for rmarkdown. It is an R package, and it is fairly easy to install from CRAN. Those who use R should be able to install it without sudo apt-get, and those who do not use R probably won't care about an R package. On the other hand, I guess a Debian version of rmarkdown that does not have ioslides can be confusing.

Regards,
Yihui

Hi Yihui Xie,

I'm considering packaging rmarkdown for Debian since several just
packaged software would profit from it. For Debian uploads I need to
make sure that each file of the source is available and has a proper
license. When I inspected the code I stumbled upon ioslides. This
project has no license in itself (neither in the code copy inside
rmarkdown) nor upstream[1]. Besides the missing license I also notice
that it contains third party components consisting of compressed
_javascript_ which is considered by Debian as "binary code" since you can
not really change it.

Do you see some means to provide a proper license for all components
of ioslides and specifically the source code of

inst/rmd/ioslides/ioslides-13.5.1/js/polyfills/dataset.min.js
inst/rmd/ioslides/ioslides-13.5.1/js/polyfills/history.min.js

where I failed to find the origin?

If not I might consider striping ioslides from the Debian package at
all by disabling the ioslides_presentation function. As far as I
can see rmarkdown is quite featureful even without this.

What do you think?

Kind regards

Andreas.
