From 4ba5a0e6851502bf0b329e3613255f71e65e78d1 Mon Sep 17 00:00:00 2001 From: Leynos Date: Sun, 23 Nov 2025 22:25:41 +0000 Subject: [PATCH 1/4] feat(stdlib/which): add workspace fallback to 'which' command lookup Enhance the 'which' command resolution logic to perform a recursive search of the workspace directory if the PATH environment variable is empty. This ensures that commands can be located within the current workspace when the standard PATH lookup fails. - Added optional CWD override support in WhichResolver and EnvSnapshot to influence environment capturing. - Integrated 'walkdir' crate for recursive directory traversal. - Implemented search_workspace function to find executables recursively in workspace. - Modified lookup behavior to try workspace search upon PATH miss when appropriate. - Updated stdlib registration to pass current workspace root as CWD override. - Improved error handling and tests accordingly.
