Yocto community, Triggered by the previous email request to yocto@ about best practices for layer organization I'm finally firing off this email for (hopefully) some feedback on an idea we first kicked around, discussed for rough consensus and then decided to implement in the Yocto based GDP project [1]. You can see it as a trial, anything can be changed, but so far so good...
We adopted a somewhat novel (but actually not really unique, see inside) naming convention [2] for all modifications to components that belong to other layers. This convention shows what layers are being modified by the .bbappends by actually naming the layer it is (intending to**) modify. The initiative also aims to highlight and separate .bbappends (modifications) from uniquely added components in our project (new .bb files) in GDP. **Note that we are well aware this does NOT control bitbake behavior (as neither does the recipe-xxx/ directory convention), and is therefore just a guide. If the project is misconfigured, bitbake could do something different than the naming convention implies and it could even be misleading, but at least the *programmer intent* is shown clearly. I think it also makes .bbappends more explicitly visible and might trigger the idea: Do we really need this? Are we really modifying *that* adopted layer, and if so, why? To Russel who wrote the previous request for guidance - feel free to consider, but I won't recommend this directly since it's by no means an agreed best practice in all of the community. I'm rather asking for other experienced OE developers to consider and comment on the idea. For oldtimers it's probably easy to find this odd and just be negative against it since well, "standard practice", inertia, NIH and all that, but I'll stick my neck out anyway because it seems to solve some issues of organization and understanding at least for us (and I'm a sucker for some flamebait ;) If the intro is too formal and long, just look at the final examples. I think you'll get it.
