Hello all,
After watching the Symfony slides about the Console, I tried giving a
wirl to finally write some much needed utilities I need when setting
up a project.
Looking at the code and through usage I have come across a possible
enhancement in the Symfony\Components\Console\DialogHelper.
The function askAndValidate, should take an extra parameter where we
can define a default that can be parsed to the closure which will
validate the $value.
A sample situation is the following:
1.) I want to ask my user for a directory destination
2.) I provide a suggestion on question that is displayed
3.) I askAndValidate, using my closure that will validate if I can
create that directory.
4.) In case I can't create the user doesn't type anything and just
presses enter, I can $value to be the one I suggested.
In order to do this, I have:
$docRootFunction = function($doc_root){
if(file_exists($doc_return $doc_root;
}
if(!mkdir($doc_root)){
throw new \Exception("The $doc_root cannot be
created");
}
return $doc_root;
};
