!! Bang-Bang operator causes error: Error in enquo(expr) : object 'x' not found about catchr HOT 3 CLOSED

So it looks like we've found ourselves what could be a rlang bug. The issue doesn't seem to be in my code (whew, close one). Check this out and tell me if you get the same type of error:

fn <- function(expr) {
  rlang::enquo(expr)
}
fn({
  t <- "time"
  t2 <- rlang::sym(t)
  rlang::quo(!!t2)
})

It looks like it has something to do with enquo() trying to turn an expression with the bang-bang operator into a quosure. This definitely isn't the behavior I would expect from rlang, so we'd better file an issue with their repo. Unless you'd like to do it yourself, I'll file a bug report with them and see if I can get to the bottom of it.

Thanks for tagging me on the issue, I'm blown away by how Henrik keeps on packing amazing features into his code (to the point where it seems like they're hard to keep track of!). I've actually been looking for a good progress tracker (for a new package I've been working on), so the progressr package seems great to know about as well.

I think the use cases for catchr are being chipped away a little bit as time goes on by future and other packages, but I still plan on maintaining it, especially while people continue to use it. Thanks for bringing this bug to my attention, and feel free to bring up any other problems/improvements you run into!

Can you try installing the dev version (devtools::install_github("burchill/catchr", ref="devel")) and see if this problem still exists for you/if you have any other problems?

If it seems good, I'll release a new version with the fix.

Seems to work fine now! Much gratitude to you for rolling out the fix so quickly and to Lionel for giving guidance on the rlang behavior that was creating the issue!
