================================== Frequently Asked Questions (FAQ) ================================== .. contents:: How do I protect the gallery with a password? --------------------------------------------- Sigal simply generates HTML pages, there is no server process that could handle a password protection. So the password has to be handled in your web server (Apache, Nginx, etc). A complete treatise on webserver configuration is beyond the scope of this document, but, for example, you may get started with Apache with the `official documentation `_. Here is an example Apache configuration, assuming your gallery was built in ``/var/www/sigal/_build``:: AuthType Basic AuthName "Restricted Content" AuthUserFile /etc/apache2/htpasswd Require valid-user You will then need to create username/password combinations in the ``/etc/apache2/htpasswd`` using the `htpasswd command `_. How do I protect only *some* folders of the gallery with a password? -------------------------------------------------------------------- This is more complicated than the above. Assuming you want to protect only the ``foo/`` subdirectory, the following will unfortunately not do what you expect:: AuthType Basic AuthName "Restricted Content" AuthUserFile /etc/apache2/htpasswd Require valid-user It *will* protect the folder with a password, but, because of the thumbnails shown on the main page, the web browser will prompt the user for a password on the parent directory as well, which will confuse users and is probably not what you want. The trick is then to whitelist the thumbnail files. Here we'll assume you will name the thumbnail files ``public.jpg`` and then configure those files to be visible even in the private section, like so:: AuthType Basic AuthName "Restricted Content" AuthUserFile /etc/apache2/htpasswd Require valid-user Satisfy any Then just make sure, through the album information mechanism, that the right image is chosen as a thumbnail for that album, for example, in ``foo/index.md``:: Title: Private section Thumbnail: public.jpg Et voilĂ ! You now have a hybrid private/public gallery. This is not recommended for highly sensitive pictures; because other parts of Sigal may (eventually?) leak information about filenames, thumbnails or even contents without your knowledge in the future. But it's a good simple way to add basic snooping protection over certain areas with minimal configuration. How to regenerate the gallery when something changes ? ------------------------------------------------------ It can be convenient to build continuously the gallery when adding or removing pictures in the albums, however Sigal does not provide currently a buitin "autoreload" feature. This can be achieved with external tool like `peat `_, `entr `_, and probably many others. For instance, with peat:: peat --dynamic 'find pictures/' 'sigal build' will watch changes inside the ``pictures/`` directory and rebuild the gallery in this case.
