Mason::Plugin::DollarDot - Allow $. as substitution for $self-> and in
Hello, <% $.name %>. Today is <% $.date %>.
# Set the date
# or, if combined with LvalueAttributes
$.date = scalar(localtime);
This plugin substitutes "$. identifier
" in all Perl code inside components, so
that $. can be used when referring to attributes and calling methods. The
actual regex is
s/ \$\.([^\W\d]\w*) / \$self->$1 /gx;
In Mason 2, components have to write "$self->" a lot to refer to
attributes that were simple scalars in Mason 1. This eases the transition
pain. $. was chosen because of its similar use in Perl 6.
This plugin falls under the heading of gratuitous source filtering, which the
author generally agrees is Evil. That said, this is a very limited filter, and
seems unlikely to break any legitimate Perl syntax other than use of the $.
special variable (input line number).
Will not interpolate as expected inside double quotes:
"My name is $.name" # nope
instead you have to do
"My name is " . $.name
