roperators 1.4.0

New features

• f() — string interpolation (“f-strings”): f("Hi {name}, you have {n} messages").
• %else% — inline fallback for an expression that might error: read.csv(path) %else% data.frame().
• %+-% — tolerance-interval constructor that composes with the between operators: x %><% (5 %+-% 0.5).
• %/0% — safe division that returns NA instead of Inf/NaN on divide-by-zero.
• %~% — case- and whitespace-insensitive string equality (the string counterpart to %~=%).
• as.percent() — format a proportion as a percentage string.

Bug fixes

• is.bad_for_calcs() now correctly flags Inf/-Inf as bad for calculations. Previously infinities slipped through, which also affected the comparison operators (%==%, %>=%, …) that rely on it.
• is.R_x64() now calls is.os_unx() correctly (it previously referenced the function without calling it).
• seq_around() now accepts ordinary numeric values for n; it previously errored unless n was given as an explicit integer (e.g. 5L).
• The between operators (%><%, %>=<%) now handle reversed bounds, so 5 %><% c(10, 1) behaves the same as 5 %><% c(1, 10).
• %na<-% now also accepts a replacement vector with one entry per missing value (filled in order), in addition to a scalar or a full-length vector.
• Removed a stray duplicate (and subtly broken) internal definition of is.bad_for_calcs().

Improvements

• as.class() is now vector-safe and no longer builds and parses code from a string internally.
• is.http_available() uses requireNamespace() instead of the much slower installed.packages().
• get_system_python(), is_rda_file(), and is_rds_file() are now exported (they were documented in earlier versions but never actually exported).

Documentation, tests & infrastructure

• Documentation overhaul for clarity and consistency: tightened every help page, fixed typos throughout, and added missing \value documentation and runnable examples.
• %rlike% and %perl% now have their own help page (“SQL-style pattern matching”) instead of being grouped under the logical operators.
• Rewritten, comprehensive vignette and a README.Rmd so the README’s output is always real.
• Added a full testthat test suite covering the operators and helpers, a BugReports URL, a pkgdown site configuration, and GitHub Actions for R-CMD-check and pkgdown deployment.
