Thank you again John for taking the time again and again to respond - totally appreciated, it's amazing. As a consequence, I took the entire day to try your solution, google frantically, but I failed miserably. I will spare you the details of everything I tried, but here is what i think is my best attempt: .1. Read carefully: https://bookdown.org/yihui/rmarkdown/template-pandoc.html .2. Download default.latex from your website: https://github.com/jgm/pandoc-templates .3. Rename the file to my-template.tex and, as per your email, line 460 just before $body$, add: $if(dayone)$ \mode { \title[\CourseName{} Lecture $lecture-number$]{\CourseName{} \newline \, Lecture $lecture-number$} \date{\DayOne{}\Yr{}} } ### \titlepage $endif$ .4. In my bookdown, add the $dayone$ custom Pandoc variable # Notations {#notations} ## Mathematics $dayone$ ```{r Lecture1Outline, eval = (out_type=="beamer"), echo=FALSE, results='asis'} ``` ```{r Lecture1Slide1, eval = (out_type=="beamer"), echo=FALSE, results='asis'} ``` `r if (out_type=="beamer") "- "` $h = \left(h_{1}, h_{2}, \ldots, h_{n}\right)$ denotes a vector (lowercase) etc. etc... .5. add "template: my-template.tex" to my YAML so that "--template my-template.tex" is being correctly added as an option to Pandoc. OUTCOME: I still get the undesired slide... "... Mathematics 𝑑𝑎𝑦𝑜𝑛𝑒 ..." I check the .rmd file. It has # Notations {#notations} ## Mathematics $dayone$ etc. etc... the .tex file has: \hypertarget{mathematics}{% \subsection{Mathematics}\label{mathematics}} \begin{frame}{Mathematics} \(dayone\) \end{frame} I am so sorry - I feel crummy I could not figure this one out after so many hours and I Thank you in advance for any further help on this issue that has drawn me for nearly 18 months. Many thanks thomas PS: note that I have before_body: beamer_prefix.tex and that works well for setting the initial cover page (syllabus) - the issue is really after, as I used this mode to redefine the elements of the title slide on the fly (day 1, 2, etc of the course) On Tuesday, August 25, 2020 at 12:22:26 PM UTC+8 John MacFarlane wrote: > > If that's what you need, then a custom template could provide it. > Just add this stuff to a custom template, with variables in the > varying parts: > > \mode > { > \title[\CourseName{} Lecture $lecture-number$]{\CourseName{} \newline \, > Lecture $lecture-number$} > \date{\DayOne{}\Yr{}} > } > ### > \titlepage > > $body$ > > "Chevrier, Thomas" writes: > > > First of all, thank you so much for taking the time to reply - really > much > > appreciated, all the more given how busy I see you are, with so many > > awesome improvements. > > I love this "raw beamer" attribute, might make my document a lot more > > readable, yet to try it for other purposes. > > Unfortunately, this suggested solution does not help the issue at stake. > > > > The issue is for the content not to get forced slapped onto a slide. > > To create a new title page, I need the following piece of code: > > \mode > > { > > \title[\CourseName{} Lecture 1]{\CourseName{} \newline \, Lecture 1} > > \date{\DayOne{}\Yr{}} > > } > > ### > > \titlepage > > > > And this {...} code cannot sit inside a frame or a latex error is thrown > (! > > Illegal parameter number in definition of \iterate.). > > After 2.7 - there is no more option for me to write content outside a > frame > > - everything is forced into a frame. > > "raw beamer" attribute does not escape this behavior unfortunately. > > > > Hence my suggestion last night - i don't know if that would be acceptable > > or even useful? > > But i have been thinking that I am perfectly fine with level -2 content > not > > being forced onto slides. > > From what I read, it looks like reveal.js users only need level -1 > content > > slapped onto slides? > > Of course, I'd be happy with any other solution you think is best. > > > > Many thank > > thomas > > > > > > On Tue, Aug 25, 2020 at 4:00 AM John MacFarlane > wrote: > > > >> > >> If you use the raw attribute to mark up content as "raw beamer," > >> as suggested earlier in this thread, it will not appear in > >> reveal.js output.
