We are using slim framework and swagger-php to dynamically generate the swagger documentation. We now have some special methods in the API that should not be publicly documentated. (/doc now) Is there any way I can have a second documentation url (/doc2) where I can get the secret methods and params documentated? (without having to make the documentation by hand, just using the annotations in the php code). Thanks.
As per the latest version of swagger-php you can indicate a list of files and/or directories to exclude from scanning when building the documentation.
See the scan function's docblock on github for details.
A solution to your problem is to separate the public and private methods into different files. Then create two documentation generation methods/functions each excluding the other's files.
Example:
$privateOptions = array(
'exclude' => array('app/api/public')
);
$privateDoc = Swagger\scan("app/", $privateOptions);
...
$publicOptions = array(
'exclude' => array('app/api/private')
);
$publicDoc = Swagger\scan("app/", $publicOptions);
Note: This example is indicative and not tested, you can also exclude filenames.
