From c479e5f527aa5319cad525e0e82467cc3592990b Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Tue, 25 Nov 2025 08:44:31 +0900 Subject: [PATCH] fix(dx): Quick Win 1-3 for better error messages and API simplification MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Quick Win 1: Show available boxes on "Unknown Box type" error - vm.rs, vm_fallback.rs: Display sorted list of available user-defined boxes - Before: "Unknown Box type: Foo" - After: "Unknown Box type: Foo. Available: Bar, Baz, Main" Quick Win 2: Show stderr on child process timeout - child.rs, selfhost_exe.rs: Capture and display stderr (up to 500 chars) - Helps diagnose what went wrong in selfhost compiler child process Quick Win 3: Simplify Stage-B compiler API (SSOT) - compiler_stageb.hako: Add StageBDriverBox.compile() as single entry point - compiler_stageb.hako: Remove StageBMain compatibility wrapper - compiler.hako: Change from `using ... as StageBMain` to direct import - compiler.hako: Call StageBDriverBox.compile() directly Also includes child_env.rs NYASH_MODULES env var for module mapping. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- lang/src/compiler/entry/compiler.hako | 7 +- lang/src/compiler/entry/compiler_stageb.hako | 83 +++++++++++++++++++ src/runner/child_env.rs | 10 +++ .../modes/common_util/selfhost/child.rs | 13 ++- src/runner/modes/common_util/selfhost_exe.rs | 11 +++ src/runner/modes/vm.rs | 27 +++++- src/runner/modes/vm_fallback.rs | 54 ++++++++++-- 7 files changed, 190 insertions(+), 15 deletions(-) diff --git a/lang/src/compiler/entry/compiler.hako b/lang/src/compiler/entry/compiler.hako index 066b88ac..cf4c28d0 100644 --- a/lang/src/compiler/entry/compiler.hako +++ b/lang/src/compiler/entry/compiler.hako @@ -2,7 +2,9 @@ // -
