From 7d69299c9f0bd3b3df6dc0c46f00a94f65fe3cfa Mon Sep 17 00:00:00 2001 From: heAdz0r Date: Sun, 15 Feb 2026 23:03:29 +0300 Subject: [PATCH] fix(grep): accept -n flag for grep/rg compatibility `rtk grep -n "pattern" path` failed with "unexpected argument '-n'" because clap didn't recognize -n before the positional arguments. Users naturally place -n before the pattern (muscle memory from grep/rg). The flag is a no-op since grep_cmd::run() already passes -n to ripgrep unconditionally, but clap must accept it. Adds -n/--line-numbers as an explicit bool field to the Grep command and ignores it in the match arm. Test added in grep_cmd::tests.
