From e5ebb30822532cddd7935d69d4d40c19a3b474fb Mon Sep 17 00:00:00 2001 From: Josh Rotenberg Date: Wed, 29 Oct 2025 21:25:49 -0700 Subject: [PATCH] feat: make --config-file take precedence over environment variables When --config-file is explicitly specified, environment variables are now ignored to provide true configuration isolation. This follows CLI best practices where explicit arguments override implicit environment. Changes: - ConnectionManager tracks whether config_path was explicitly provided - create_cloud_client() and create_enterprise_client() skip env var checks when config_path is Some() - ApiCommandParams now includes config_path to preserve it through API command execution - Added debug logging to show when env vars are being ignored Tests: - test_config_file_overrides_env_vars: verifies env vars are ignored when --config-file is specified - test_env_vars_work_without_config_file: verifies env vars still work when --config-file is not specified This provides true configuration isolation for testing and follows the principle of "explicit wins" (CLI args > env vars > defaults).
