Creating a new recipe with ddev recipe-create badly fails with File "components.composer.json" cannot be found in the current directory

Hah, whoops. Thanks for that.

ddev recipe-create isn't meant to be used by consumers of Drupal CMS, though; it's just for internal development. Self-assigning to fix this.

I'm just gonna remove them.

Oh, one other thing:

referring to this official instructions

Those instructions are not official! Nothing in the wiki constitutes official documentation. I'll update it to explicitly say that.

So long, scripts! Merged into 1.x.

Ok... got it,
But @phenaproxima as for the officiality of that wiki page, well
note that there is still a clear link to that in the Readme.md file itself (https://git.drupalcode.org/project/drupal_cms/-/blob/1.x/README.md?ref_t...)

another question, sorry @phenaproxima
as you just removed what looked an practical tool for easily generate a Drupal Recipe,
is it out there any handy way / tool, or even instructions on how to to easily generate a Drupal Recipe, from a working Drupal site?
I couldn't find any, so far ...
Only this looks aiming to that goal: https://www.drupal.org/project/recipe_generator →
but it also looks pretty outdated and not supporting Drupal 11.

It was not, and never was, a practical tool to generate a recipe. It was only meant to be a convenience layer to add a new recipe stub to Drupal CMS itself. As I said -- it was for contributors. It wasn't well documented, because it was, well, internal! :)

It doesn't generate a "recipe", per se - all it did is generate is a composer.json file (if you read the script from the git history, you'll see that for yourself). Recipes themselves still need to be constructed by hand. I'm not aware of any tool to generate a recipe from an extant Drupal site, but I know a lot of people are interested in that. I suspect it's on the Recipes Initiative's roadmap, probably phase 3.

Thanks @phenaproxima for your clarifications .... and all your time!
