`hasFun("modifyRange")` returns `FALSE`

[howardbaik]

rstudioapi::hasFun("modifyRange") returns FALSE for some reason and I'm not sure why. It looks like modifyRange() is an exported function from the rstudioapi package. I looked at the help file for hasFun() and it implies that modifyRange() does not exist in the "rstudio package namespace".

This question stems from encountering an error in an addin from the golem package. I tried to insert ns() using the addin and got this message: Your version of RStudio does not support modifyRange. This message is ultimately caused by hasFun <- rstudioapi::hasFun(fun) returning FALSE.

I'm using rstudioapi version 0.17.1 and RStudio version 2024.12.1.

This is because rstudioapi::modifyRange() actually calls an API function insertText instead; it unfortunately deviates from the typical pattern of RStudio API functions. Which is to say -- I think this is an RStudio bug, and we should add that API for completeness.

This will be fixed in the next release of RStudio, For now, I'd recommend testing the version of RStudio to see if the modifyRange API is available, rather than using hasFun(). Thanks for the report!

Thanks for the prompt reply.

Just to clarify, are you suggesting something along the lines of

is_modifyRange_available <- function() {
  if (!rstudioapi::isAvailable()) return(FALSE)

  version_info <- rstudioapi::versionInfo()
  required_version <- package_version("XXX")  # XXX = next release of RStudio

  return(!is.null(version_info$version) &&
         version_info$version >= required_version)
}

I would like to incorporate this function into the golem package.

Also, when will be next release of RStudio be? Thanks!

[kevinushey]

Yeah, that's right.

Also, when will be next release of RStudio be? Thanks!

I don't think we have a set date yet, but likely within the next couple of months.
