From 40f194b2ce0c9f37c9e522cca72abf32be1f4dba Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 26 Jul 2026 16:26:41 +0000 Subject: [PATCH 1/3] refactor: move optional arguments of operators functions behind the ellipsis Insert `...` between the defining arguments and the optional modifiers of 4 functions, following the zoning rules in CONTRIBUTING.md. Legacy positional and abbreviated calls are recovered by the generated ARG_HANDLE blocks (registry: tools/migrations/operators.R) and emit a single soft deprecation for igraph 3.0.0. No defaults change and no arguments are renamed. Functions: complementer, compose, each_edge, keeping_degseq Co-Authored-By: Claude Fable 5 Claude-Session: https://claude.ai/code/session_016M32izVHZPfxAqemAe4BrX --- R/cycles.R | 1 + R/operators.R | 83 +++++++++++++++++++++++++++++++++++- R/rewire.R | 28 ++++++++++++ man/complementer.Rd | 4 +- man/compose.Rd | 3 ++ man/each_edge.Rd | 3 ++ man/keeping_degseq.Rd | 2 + tools/migrations/operators.R | 48 +++++++++++++++++++++ 8 files changed, 170 insertions(+), 2 deletions(-) create mode 100644 tools/migrations/operators.R diff --git a/R/cycles.R b/R/cycles.R index c3d65b5cae0..25356203038 100644 --- a/R/cycles.R +++ b/R/cycles.R @@ -31,6 +31,7 @@ #' a specific cycle. #' #' @param graph The input graph. +#' @inheritParams rlang::args_dots_empty #' @param mode Character constant specifying how to handle directed graphs. #' `out` follows edge directions, `in` follows edges in the reverse direction, #' and `all` ignores edge directions.
