Object::Declare 0.13

Object::Declare is a Perl module for declarative object constructor. SYNOPSIS use Object::Declare [MyApp::Column, MyApp::Param]; my %objects = declare { param foo => !is global, is immutable, valid_values are qw( more values ); column bar => field1 is value, field2 is some_other_value; }; print $objects{foo}; # a MyApp::Param object print $objects{bar}; # a MyApp::Column object This module exports one function, declare, for building named objects with a declarative syntax, similar to how Jifty::DBI::Schema defines its columns. In list context, declare returns a list of name/object pairs in the order of declaration (allowing duplicates), suitable for putting into a hash. In scalar context, declare returns a hash reference. Using a flexible import interface, one can change exported helper functions names (declarator), words to link labels and values together (copula), and the table of named classes to declare (mapping): use Object::Declare declarator => [declare], # list of declarators copula => { # list of words, or a map is => , # from copula to prefixes for are => , # labels built with that copula } aliases => { # list of label aliases: more => less, # turns "is more" into "is less" # and "more is 1" into "less is 1" }, mapping => { column => MyApp::Column, # class name to call ->new to param => sub { # arbitrary coderef also works bless(@_, MyApp::Param); }, }; After the declarator block finishes execution, all helper functions are removed from the package. Same-named functions (such as &is and &are) that existed before the declarators execution are restored correctly..
