cat(str_quote(x), "\n")
#> 'test' 
# format a set of character values with str_vector()
vec <- c("item1", "item2", "item3")
cat(str_vector(vec)) # single quote (default)
#> 'item1', 'item2', 'item3'
cat(str_vector(vec, qchar = "double")) # double quote
#> "item1", "item2", "item3"
# print post-processing with str_reformat()
txt <- "hello
