The most common use of Mason is to generate dynamic web content.
Poet is a web framework designed specifically to work with Mason. Given an
HTTP request, Poet generates a corresponding Mason request, and uses the output
from Mason to form the HTTP response. Poet takes care of the web development
details that are outside of Masons domain, such as server integration and
configuration. Poet::Manual::Tutorial shows how to
set up a Poet/Mason site in great detail.
Mason can also be used in the popular web frameworks Catalyst and
Dancer, as a drop-in replacement for their default template engines.
See Catalyst::View::Mason2 and
Mason can be used to generate any kind of dynamic content. I have personally
used it to generate Apache configuration files, emails, and C++ code.
To use Mason from a script or library, use the Mason::Interp API:
my $interp = Mason->new(
comp_root => /path/to/comps,
data_dir => /path/to/data,
my $output = $interp->run( /request/path, foo => 5 )->output();
If you want to process a directory with a mix of Mason templates and static
files, check out Any::Template::ProcessDir.
To try out Mason syntax from the command line, use the mason script:
2 + 2 = <% 2+2 %>
2 + 2 = 4
