Feature request: ability to prefer all functions in package

[rossellhayes]

Certain packages, like tidylog and wisegroup, are designed to mask multiple functions in another package. If these packages are used with conflicted, the user will have to include numerous calls to conflict_prefer() to avoid errors. An alternative is to provide a function, e.g. conflict_always_prefer(), that allows the user to prefer all functions exported from a package.

One way to implement this would be:

conflict_always_prefer <- function(winner, losers = NULL, quiet = FALSE) {
  invisible(
    lapply(getNamespaceExports(winner), conflict_prefer, winner, losers, quiet)
  )
}

# For example
conflict_always_prefer(winner = "tidylog", losers = c("dplyr", "tidyr"))

This is also the case for vroom and readr. I'd like to conflict_prefer() the here::here() function over lubridate::here() yet not have to specify every vroom::col_*() function.

What about an additional regex = FALSE argument to conflict_prefer, we could do conflict_prefer(".*", "tidylog", regex = TRUE) to prefer all tidylog functions, or conflict_prefer("^col_.*", "vroom", regex = TRUE) to prefer all vroom::col_*() functions.

I think this is an excellent solution!

Implemented as conflict_prefer_all() and conflict_prefer_matching().
