This release is mostly bug fixes, but there are a couple of new features you might care out.
There are three new datasets, fruit
, words
and sentences
, to help you practice your regular expression skills:
More functions work with boundary()
: str_detect()
and str_subset()
can detect boundaries, and str_extract()
and str_extract_all()
pull out the components between boundaries. This is particularly useful if you want to extract logical constructs like words or sentences.
x <- "This is harder than you might expect, e.g. punctuation!"
x %>% str_extract_all(boundary("word")) %>% .[[1]]
#> [1] "This" "is" "harder" "than" "you"
#> [6] "might" "expect" "e.g" "punctuation"
x %>% str_extract(boundary("sentence"))
#> [1] "This is harder than you might expect, e.g. punctuation!"
str_view()
and str_view_all()
create HTML widgets that display regular expression matches. This is particularly useful for teaching.
