But do not open them!
Having all the exercises as folders within parent_path makes it possible
to resolve them one by one, if one wants to practice all that is available
with the package.
Run this function only if there are no exercise folder already created in
parent_path: you can use a brand-new folder for instance.
Workflow
Running the function will create the exercise as a new folder in parent_path.
If called from RStudio or Positron, the function will open a new R session in
that IDE.
If not, the user will need to navigate to the path returned by the function,
and launch an R session from there.
The new R session will display messages about what challenge to solve,
and running the tip() function from that new R session will display
additional guiance.
Examples
if (FALSE) { # interactive()
parent_path <- withr::local_tempdir()
path <- create_all_exercises(parent_path = parent_path)
}
