From 253a2d48083769d934cedd1afcdcd32ce6ebb7af Mon Sep 17 00:00:00 2001 From: srpatcha Date: Sat, 29 Aug 2026 11:02:10 -0700 Subject: [PATCH] feat(cli): refuse packages that cannot resolve, and summarise what the build contained MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two gaps against the MLP developer walk, which runs `ebuild add wifi` and then expects a build that says what it contained. `ebuild add` warned about an unknown package and added it anyway: $ ebuild add wifi [warn] No recipe found for 'wifi' — adding anyway. [ok] Added wifi to build.yaml That trades one clear error now for a confusing one at build time, in a file the developer has since committed. It now refuses, and says what would help: $ ebuild add wifi [error] No recipe for 'wifi'. Available: freertos, littlefs, lwip, mbedtls, zlib To add it anyway: ebuild add wifi --force $ ebuild add lwipp [error] No recipe for 'lwipp'. Did you mean: lwip? `--force` keeps the old behaviour for anyone who genuinely wants an entry ahead of its recipe, and says plainly that it will not resolve. Refusing without an escape hatch would be the other kind of unhelpful. The build then reports what it actually contained: EmbeddedOS Build OK toolchain arm-none-eabi-gcc OK board configuration stm32f4 OK lwip MISS mqtt declared, nothing resolved OK temperature-monitor executable The case worth having is MISS. A package that resolved to no include or library directory contributed nothing, whatever build.yaml says -- the build still succeeds, the feature is simply absent, and until now nothing said so. The summary is rendered through the logger in the tests, so the assertions are on what a developer actually sees rather than on an intermediate structure. 271 tests pass, up from 255; 16 are new here.
