Converts an app atom to its expected module prefix string.

Examples

iex> CodeStory.Modules.camelize_app_name(:my_app)
"MyApp"

@spec detect() :: [module()]

Detects user-defined modules from the current Mix project.

Returns a list of modules whose top-level namespace matches the app name from Mix.Project.config()[:app], including the app's Web namespace (e.g. :my_app matches MyApp.* and MyAppWeb.*, the conventional Phoenix split).

@spec ecto_repos([module()]) :: [module()]

Filters the given modules to those that are Ecto repos.

Detection is runtime duck-typing — a repo is any module exporting __adapter__/0 (which use Ecto.Repo defines). CodeStory has no compile-time dependency on Ecto.

Code.ensure_loaded?/1 is required: function_exported?/3 returns false for a merely-loadable-but-unloaded module and will not load it, and detection can run before the tracer forces modules to load.
