before_chapter_script also needs to be run by preview_chapter about bookdown

[cderv]

Hi @mbojan ,

This is an old issue and not suitable to ask for something like that 4 years later. Moreover, yes this is supposed to work.
Please open a new issue and provide some more information (a reproducible example would be great) so that we can look into it.

Thank you !

This still isn't working for me - I have

knitr::opts_chunk$set(
  comment = "#>",
  collapse = TRUE,
  cache = TRUE
)

but the chunks aren't getting the style I want (or cached)

[hadley]

Also this now seems to be running in the main directory (instead of _book) so the chapter number is incorrect, and I get intermediate outputs in the root dir

Hmm, I cannot reproduce it with your r4ds repo. The _common.R script is inserted before chapters as expected. Intermediate outputs are also moved to _book. *_files/ and *_cache/ are not moved, though, but that is intentional (I guess I could move them if you want).

[hadley]

Hmmm, now it looks ok for me too. Maybe I was looking at a cached version?

I did expect the _files/ and _cache/ to go in _book too. Can you explain why they're not moved automatically?

[yihui]

I was simply waiting for you to complain about it :)

For the merge-and-knit approach, these are only two directories, so this does not bother me too much. I know it will be messy for the knit-and-merge approach, and apparently you do not like it, so I'll move them. The Rmd's are compiled in the root directory, and the outputs are moved to _book later. If I move _cache to _book, I'll have to move it back to the root directory the next time I compile an Rmd (then move it to _book again).

@yihui , is this resolved? I believe I ran into the same problem. I have new_session: true in _bookdown.yml and the before_chapter_script is not executed when previewing a chapter in RStudio (with the "Knit" button).

You are right @cderv , apologies. New issue incoming.
