(new to 5.0) @export fails to export if there is another #' before the function/object

[ttriche]

This is new. I can work around it by removing said formatting, but it seems rather brittle and flaky.

[hadley]

Could you please provide a reproducible example?

[ttriche]

sure, see ttriche/roxpkg , specifically hello.R and goodbye.R

The comment about @export spanning more than one line seems to be new(ish) and wasn't getting thrown previously (in the package I was working on earlier), just mysteriously not exporting anything.

[hadley]

Could you please include a reproducible example inline?

[ttriche]

How? The problem occurs when I run devtools::document() or
roxygen2::roxygenise() from within the package root.

That's also how I was most easily able to reproduce the problem. I'm not
sure how to provide an inline example of an error that seems to occur in a
context-dependent fashion. If there's a trailing #' after #' @export, the
function isn't exported. This behavior is new. That's all I'm saying.

The repo that I threw up demonstrates it in the simplest way I could think
of.

Copy and paste the code from your repo into this issue. Or at least paste a link to the file within the repo.

In the past, there was no difference between the following re: NAMESPACE. Now, there is.

#' Hi, I'm exported!
#'
#' @param txt       what to say
#'
#' @export
hello <- function(txt = "world") {
    cat("Hello, ", txt, "\n")
}

#' Hi, I'm not exported!
#'
#' @param txt       what to say
#'
#' @export
#'
goodbye <- function(txt = "world") {
    cat("Goodbye, ", txt, "\n")
}

Thanks - that's helpful. The fewer links I need to follow, the faster I can fix the problem - in future, it would also be helpful if you include the text of the error message. That makes it even faster for me to track down.

[ttriche]

Thanks!

@hadley @klutometis This is still not working for me. I have to move #' @export above another roxygen2 tag to make it work. From a fresh session details below.

Intriguingly, the bug is itself buggy. That is, it doesn't reproduce consistently. For example

file1.R
#' @title ...
... blah blah ...
#' @export
foo <- function(a,b,c) {<some function>} # works fine

file2.R
#' @title ...
... blah blah ...
#' @export
foo2 <- function(a,b,c) {<some function>} # doesn't work, but 

file2.R
#' @title ...
... blah blah ...
#' @export
#' <any other roxygen tag, such as examples or reference>
foo <- function(a,b,c) {<some function>} # works fine

Observing the same behavior as "I have to move #' @export above another roxygen2 tag to make it work." with current version 6.1.0.9000.

@zkurtz commenting on closed issues usually will not get you very far. Can you please open a new issue with a reproducible example? Or some of the examples above fail for you?
