WWW::Kontent - Highly extensible Perl 6 CMS
Kontent is a web content management system written in Perl 6. It is currently executable in Pugs installations with Parrot available; the storage subsystem included in this installation also requires the Perl 5 interop feature, but an alternate system could be written.
Kontent's basic principle is separation of concerns: whenever possible, the system is separated into swappable components. The webmaster chooses a "supervisor" to interface with their web server and a "store" to hold all pages in the system; individual pages have different "classes" implementing different behaviors; and each page can be displayed with any of several "renderers".
Kontent is simple enough to need only a small amount of configuration, and flexible enough to meet the needs of almost any site. It takes care of the niggling details of web design--tasks like revision control, site templating, and user contributions--leaving only the task of plugging in your own content.
Currently only the CGI supervisor is written, and the only useful store is NarrowDBI. This somewhat simplifies the task of configuring Kontent.
Configuring Kontent takes four steps:
Point your web server at the appropriate supervisor somehow. See test.p6 for information on this.
Edit kontent-config.yaml with the modules you want to be loaded and your store's configuration.
Create the database the store interfaces with.
Create the root node:
pugs -MWWW::Kontent -e 'WWW::Kontent::make_root'
Some day there should be a set of CGI scripts to automate all of this.
WWW::Kontent first loads several core Kontent modules, including WWW::Kontent::Foundation, WWW::Kontent::Exceptions, WWW::Kontent::Request, and WWW::Kontent::Skeleton. It then reads Kontent's configuration file, kontent-config.yaml, from the same directory the supervisor is in. It loads all the modules specified in the
modules configuration group, then curries the specified store's
get_root functions to receive the store configuration, storing the resulting functions in
It also contains two functions,
register_renderer, and the corresponding hashes
%renderers. These are used to register and locate classes and renderers, respectively. Both functions take a string containing the class or renderer's name (like 'kiki') and the class that name refers to.
Plenty, no doubt; this is an early alpha of an incomplete system written in an experimental language with a constantly-changing interpreter. In particular, be on the lookout for intermittent bugs in Perl 5 interop; these usually manifest as an inability to find DBI methods like
Basically, you'd be nuts to try to use this for real right now.
