Is there a global option to adjust the default setting of tibbles that displays only 10 rows?

Question

I often use tibbles and am quite satisfied with them. The only recurring issue that bothers me is having to constantly add print(n = ...) every time I want to view more than 10 rows. I'm aware that I could convert them to data frames using as.data.frame(), but I'd prefer to set a global print option, such as print(n=100), for all tibbles until I decide to change it.

So far, what I've been doing is

using print(n=....)

library(dplyr)

mtcars %>% 
  as_tibble() %>% 
  print(n=20)

or using as.data.frame()

mtcars %>% 
  as_tibble() %>% 
  as.data.frame()

or with a custom function (similar to data.table feature)

tar_head_tail <- function(data, nh = 15, nt = 15) {
  library(dplyr)
  library(crayon)
  
  x <- data %>%
    as.data.frame() %>%
    tibble::rownames_to_column("row_number") %>%
    head(n = nh)
  
  y <- data %>%
    as.data.frame() %>%
    tibble::rownames_to_column("row_number") %>%
    tail(n = nt)
  
  head_tail <- bind_rows(x, y) %>%
    tibble::column_to_rownames("row_number")
  
  # Apply color
  cat(green("Head:\n"))
  print(x)
  cat(red("\nTail:\n"))
  print(y)
  
  return(invisible(head_tail))
}

iris %>% 
  tar_head_tail()

How can we set a global print (such as print(n=20)) option for all tibbles until we decide to change it?

Update: What I expect:

When I do:

mtcars %>% 
  as_tibble()

it should show after setting global print(n=20):

# ℹ 12 more rows

I want to avoid the additional line of print(n=....), or print() etc...

dplyr and other tidyverse packages import pillar for formatting printed output. The docs list various options to control how tibbles are printed.

For rows:

pillar.print_max: Maximum number of rows printed, default: 20. Set to Inf to always print all rows.

pillar.print_min: Number of rows printed if the table has more than print_max rows, default: 10.

options(pillar.print_min = 100)

mtcars |>
    dplyr::as_tibble()
# prints all 32 rows of mtcars

iris |>
    dplyr::as_tibble()
# prints the first 100 rows of iris
