ioslides_presentation ignores the template option

[ignacio82]

I have a presentation with a personalized template

output: 
    ioslides_presentation:
       template: ./templates/mytemplate.html

But rmarkdown is ignoring that option and using the default template

/usr/lib/rstudio-server/bin/pandoc/pandoc /tmp/RtmpP2Yo3D/EdCenter.utf8.md --to html --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash-implicit_figures --output /tmp/RtmpP2Yo3D/file6f62a7095b9.html --smart --email-obfuscation none --variable widescreen --variable transition=0 --css styles/MPR_Ioslides_Styles.css --template /usr/local/lib/R/site-library/rmarkdown/rmd/ioslides/default.html --mathjax --variable ioslides-url=file6f62a7095b9_files/ioslides-13.5.1 
/usr/lib/rstudio-server/bin/pandoc/pandoc /tmp/RtmpP2Yo3D/EdCenter.utf8.md --to ioslides_presentation.lua --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash-implicit_figures --output /tmp/RtmpP2Yo3D/ioslides-output6f66dbcb94b.html 

Is this a bug or am I doing something wrong?

Thanks a lot!

It's because the template is a property of the ioslides_presentation format (and therefore needs to be indented below it rather than at the same level).

@jjallaire it is indented, makes no difference

[jjallaire]

Okay, sorry about the mixup there.

ioslides_presentation doesn't actually support custom templates (it doesn't have a template argument). This is mostly because ioslides is not a format natively supported by pandoc so the built in template has a lot of special sauce.

All of that said, you could workaround this by creating a new format that just calls ioslides_presentation and then modifies the pandoc args to point to your template.

@jjallaire I think http://rmarkdown.rstudio.com/ioslides_presentation_format.html says that ioslide supports template: "You can also replace the underlying pandoc template using the template option:"

If that is incorrect, can you point me in the right direction to create a new format? If I go that route, will I be able to upload the presentation to shinyapps.io ??

Right now what I'm doing is replacing /usr/local/lib/R/site-library/rmarkdown/rmd/ioslides/default.html in my computer with my file. But, that workaround does not work with shinyapps.io nor is very convinient for most users

Thanks!

[jjallaire]

Unfortunately the docs are wrong there (I'll update them).

Here are the docs on creating a custom format: http://rmarkdown.rstudio.com/developer_custom_formats.html

Hopefully you can sort out what you need from there (the resulting template should indeed work on shinyapps.io).

one more question. Can you point me to the ioslide format file? It will probably make sense to use it as my starting point.

Thanks a lot!

[ignacio82]

I was able to use this repository as my starting point and modify ioslides_presentation.R to change the theme. Right now I'm using an absolute path instead of a relative path. That is:

 args <- c(args,
            "--template",
            pandoc_path_arg("/home/ignacio/MySlides/inst/rmd/ioslides/template.html"))

Where MySlides is the package that I created based on this one. Can you tell me how to change that to a relative path?

Thanks a lot!

[jjallaire]

You can use the system.file function as a way of creating a relative path:

system.file("rmd/ioslides/template.html", package="MySlides")

@jjallaire Inside 'skeleton' I have a folder 'images' and inside that folder 'partner.png'. So when I create a rmarkdown using my template that folder and file are automatically created. is there a way of using relative path to that file?

Basically, I'm trying to modify this part of the default.html:

$if(logo)$
    slides > slide:not(.nobackground):before {
      font-size: 12pt;
      content: "";
      position: absolute;
      bottom: 20px;
      left: 60px;
      background: url($logo$) no-repeat 0 50%;
      -webkit-background-size: 30px 30px;
      -moz-background-size: 30px 30px;
      -o-background-size: 30px 30px;
      background-size: 30px 30px;
      padding-left: 40px;
      height: 30px;
      line-height: 1.9;
    }
$endif$

My goal is to have partnet.png in the bottom right corner and $logo$ in the bottom left.

Thanks a lot!

[jjallaire]

Yes, just set the URL to images/partner.png rather than $logo$

It doesn' t work. Can you recommend me a way to debug this? Sorry to be a pain, this is very new to me.

If I do url("$ioslides-url$/images/other.png") for example, the logo changes to other.png but that file is inside the library instead of the project folder, and therefore an user cannot change it by just replacing a file.

[jjallaire]

Sorry I don't have time to debug this right now :-\

I understand, thanks for all the help!

@jjallaire sorry to revive an old thread, i am having the same issue where I would like to set my own template for ioslides_presentation. In your second reply above, you seem to indicate that you can choose a new template by setting the pandoc_args, i.e.,

  temp <- rmarkdown::pandoc_path_arg(system.file("rmd/ioslides/default.html",
                                                 package="mypackage"))
  rmarkdown::ioslides_presentation(pandoc_args = c("--template", temp), ...)

However, the problem is that ioslides_presentation adds its own "--template" to the pandoc call, so now two "--template" options are specified. Is there a way to avoid this without re-writing a new ioslides_presentation?

btw, it would be convenient and simple to modify ioslides_presentation() to allow for a template argument.

[jjallaire]

No, you can't create your own template for ioslides_presentation because that is a custom format written with Lua (it's not a built-in pandoc format).

Closing since the original issue seems to have been resolved. There are a couple of of more issues, but I guess they are unlikely to be addressed in the future. You may try some other packages such as xaringan and revealjs and see if you like them. More info: https://github.com/rstudio/rmarkdown/pull/404#issuecomment-326354500
