Match any character(s) at least once.

Source: R/rules.R

This expression is almost identical to rx_anything() with one major exception, a + is used instead of a *. This means rx_something() expects something whereas anything() expects anything including... nothing!

rx_something(.data = NULL, mode = "greedy")

Arguments

.data

Expression to append, typically pulled from the pipe %>%
mode

Matching mode (greedy (default) orlazy). Lazy matching stops after the first match, greedy continues searching until end of the string and then back-tracks to the last match.
