v0.6.4 (2024-05-25)

Release Notes

New features

• New function r_warn() safely show a warning. Note that, a warning can raise
  error when options(warn = 2), so you should not ignore the error from
  r_warn(). The error should be propagated to the R session.

• Savvy now translates Option<T> as an optional argument, i.e., an argument
  with the default value of NULL.

  Example:

  #[savvy]
  fn default_value_vec(x: Option<IntegerSexp>) -> savvy::Result<Sexp> {
      if let Some(x) = x {
          x.iter().sum::<i32>().try_into()
      } else {
          (-1).try_into()
      }
  }

  default_value_vec(1:10)
  #> [1] 55
  
  default_value_vec()
  #> [1] -1

Bug fixes

• r_print!() and r_eprint!() now can print strings containing %.

Breaking Change

• The notation for savvy-cli test is now changed to #[cfg(feature = "savvy-test")] from #[cfg(savvy_test)]. This is to avoid the upcoming
  change in Cargo (ref).
