I understand the interest, but I don't think it fits into the core framework because it amounts to quite a bit of extra processing for a very specific niche interest (don't worry, I'm totally picky about my code & names too). The problem is that we need to take a route and match it to an actual filename, and "mycontroller/mymethod" could be millions of different manifestations of "mYcOnTrollEr/MyMEthod" since there's no telling where the words split apart. So the fallback is a filesystem search like "foreach ($files as $name) { if strtolower($name) == strtolower($controller))... }" but that's a filesystem read on every autoroute which is a performance hit.
If you really want it you can extend Router\Router yourself. There relevant code is around line 530:
PHP Code:
/**
* Attempts to match a URI path against Controllers and directories
* found in APPPATH/Controllers, to find a matching route.
*
* @param string $uri
*/
public function autoRoute(string $uri)
{
$segments = explode('/', $uri);
$segments = $this->validateRequest($segments);
// If we don't have any segments left - try the default controller;
// WARNING: Directories get shifted out of the segments array.
if (empty($segments))
{
$this->setDefaultController();
}
// If not empty, then the first segment should be the controller
else
{
$this->controller = ucfirst(array_shift($segments));
}
Notice this last part -------^^^^ that simply sets the controller to "ucfirst() of the first segment".
For kebab-case also notice the Router property translateURIDashes - it swaps dashes for underscores but could also be modified.
