NAME Catalyst::Controller::BindLex - Stash your lexical goodness. SYNOPSIS package MyApp::Controller::Moose; use base qw/Catalyst::Controller::BindLex/; sub bar : Local { my ( $self, $c ) = @_; my $x : Stashed; my %y : Stashed; $x = 100; do_something( $c->stash->{x} ); # 100 $c->forward( "gorch" ); } sub gorch : Private { my ( $self, $c ) = @_; my $x : Stashed; do_something( $x ); # still 100 } sub counter : Local { my ( $self, $c ) = @_; my $count : Session; $c->res->body( "request number " . ++$count ); } DESCRIPTION This plugin lets you put your lexicals on the stash and elsewhere very easily. It uses some funky modules to get it's job done: PadWalker, Array::RefElem, Devel::Caller, Devel::LexAlias and attributes. In some people's opinion this hurts this plugin's reputation ;-). If you use the same name for two variables with the same storage binding attribute they will be aliased to each other, so you can use this for reading as well as writing values across controller subs. This is almost like sharing your lexical scope. WHY ISN'T THIS A PLUGIN? The way attributes are handled this can't be a plugin - the MODIFY_SCALAR_ATTRIBUTES methods and friends need to be in the class where the lexical is attributed, and this is typically a controller. CONFIGURATION You can add attributes to the configaration by mapping attributes to handlers. Handlers are either strings of methods to be called on $c with no arguments, which are expected to return a hash reference (like "stash", "session", etc), or code references invoked with $c, a reference to the variable we're binding, and the name of the variable we're binding, also expected to return a hash reference. DEFAULT ATTRIBUTES Some default attributes are pre-configured: Stash, Stashed Session, Sessioned Flash, Flashed Bind the variable to a key in "stash", "session" or "flash" respetively. The latter two require the use of RECIPES Param To get my $username : Param; add __PACKAGE__->config->{bindlex}{Param} => sub { $_[0]->req->params }; AUTHORS Matt S.
