this may be trivial or simply impossible, but I would like to allow the date of a blogdown "talk" to be determined by a R expression. The way I thought about it something like that
# Some R code to define a variable 't0', which is a string to contain the start date in
# a format that `blogdown` will like for the yaml field 'date'
---
title: My title here
date: '`r t0`'
### Other yaml variables
---
I assumed that that would work, but instead, I get an error
Quitting from lines X-XX ()
Error in eval(parse_only(code), envir = envir) : object 't0' not found
Looks like the R code is not "ported" onto the yaml? (I have managed in blogdown to use the !expr SOME_R_INLINE_EXPRESSION to add a variable to the yaml, but in this case it just doesn't seem to work...).
Am I missing something obvious?
Thanks Gianluca
