0.5.0 - 2026-07-16

Release Notes

Driven by the ranks-301-500 audit (ry 0.4.0 on the top-500 CRAN packages).
Minor bump: RY050's dispatch semantics, RY097's collapse criteria, and the
new binding/quoting/narrowing rules intentionally change reported
diagnostics between versions.

Performance

• Pipe-chain inference was exponential: each %>%/|> stage re-inferred
  its entire left-hand side inside the desugared call, so a 20-stage chain
  took ~14 s and longer chains never finished. The inferred LHS type is
  now reused. gt (289 R files, previously unscannable) checks in ~2.4 s.
• The required-parameter force-flow analysis walked each if branch twice
  (once for "forces", once for "falls through"), which is exponential on
  long else if dispatcher chains. Both facts are now computed in one
  pass. lavaan and stargazer (previously >60 min, never completed) check
  in ~2.3 s and ~0.8 s.

Fixed

• assign("name", value, envir = ...), makeActiveBinding(), and
  delayedAssign() with a literal name now create package-level bindings
  (any nesting depth under R/). Removes whole-package RY010 cascades in
  clock (204 -> 0), rJava, otel, parallelly, and others. .packageName
  is bound in every package namespace.
• A string-literal assignment target ("Math.foo" <- function(...)) now
  binds, aliases, and establishes S3 dispatch context (.Generic,
  .Method) exactly like an identifier target (chron 35 -> 10).
• alist() arguments are quoted, never resolved as variables, and the
  call returns a list (Deriv 111 -> 8, ade4 RY010 42 -> 2).
• A union whose members are all functions is callable; RY070 no longer
  fires on f <- if (p) function(...) ... else function(...) followed by
  f(...). Argument checks report only findings that hold for every
  member signature. NULL/function unions still report RY070.
• RY097 (not-R-source) now also collapses files that mostly parse as R
  but are riddled with parse errors (>= 5 errors and >= 15% of top-level
  statements): Ratfor, GAUSS, and markdown-table files under inst/
  (pacman 270 -> 27, plm 136 -> 36 total).
• is.list()/is.function()/is.environment()/is.data.frame() guards
  narrow a parameter whose type came only from its default, so
  f <- function(x = FALSE) if (is.list(x)) x$field no longer reports
  RY061 (visNetwork 34 -> 5 RY061).
• Assignments nested inside call arguments of if/while conditions
  (if (grepl(p, ti <- text[i]))) now bind in the enclosing scope
  (litedown 27 -> 10).
• RY033's message no longer claims R compares "byte values"; R coerces
  the numeric operand to character and compares lexicographically.
• The typeshed ships registered-but-unexported base S3 methods (e.g.
  stats:::print.anova), so RY050 no longer reports them missing
  (spatial, Cairo). RY050 also honors <generic>.default as a valid
  dispatch fallback: coef(glm_fit) no longer reports a missing
  coef.glm. Consequently RY050 can no longer fire for generics that
  have a .default method (such as print) — dispatch always succeeds
  for them.

Removed

• RY095 (negation-comparison-precedence) is retired. The rule assumed C
  operator precedence, but R gives unary ! lower precedence than
  comparison operators: !x == y parses as !(x == y), so every flagged
  site was correct code and the suggested rewrite was a semantic no-op.
  The rule number will not be reused.

Fixed

• RY096 no longer fires in functions whose formals include ...:
  there, hasArg(name) legitimately tests for a dots-supplied argument
  (if (hasArg(b)) list(...)$b). All 84 corpus hits were this idiom.
  The rule now only flags the provable case — a hasArg() naming a
  non-formal in a function without ... is always FALSE.

Corrections to 0.4.0 release notes

• The scales !length(x) == 1 guards cited as newly found bugs were not
  bugs; they parse as length(x) != 1 and behave as intended. The same
  applies to RY095 reports in rpart, mice, quantreg, spdep, and mlflow.
