From 22575aa1db2f032a05d9a2b55baf08adabefbaa9 Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Tue, 25 Nov 2025 07:18:29 +0900 Subject: [PATCH] refactor(selfhost): clean up selfhost.rs - remove duplicates, unify env access MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Changes ### Duplicate code removal - Remove nested double cli_verbose() checks (2 places) - Remove duplicate pre_run_reset_oob_if_strict() calls - Remove duplicate OOB strict check blocks ### Environment variable access unification - All raw std::env::var() calls replaced with config::env functions - Added new config::env functions: - ny_compiler_use_py() - macro_selfhost_pre_expand() - scopebox_enable() - loopform_normalize() - selfhost_inline_force() ### Common helper extraction - maybe_dump_mir_verbose(): MIR dump with verbose check - check_oob_strict_exit(): OOB strict mode check and exit - execute_with_oob_check(): Combined run + OOB check ## Result - Net ~11 lines reduction - Much better code structure and maintainability - Consistent environment variable access through config::env 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/config/env.rs | 127 ++++++++++++++++++++----------------- src/runner/selfhost.rs | 138 +++++++++++++++++------------------------ 2 files changed, 127 insertions(+), 138 deletions(-) diff --git a/src/config/env.rs b/src/config/env.rs index 4b05ca8e..88877888 100644 --- a/src/config/env.rs +++ b/src/config/env.rs @@ -3,6 +3,13 @@ //!
