NAME

       MooseX::Declare::Context - Per-keyword declaration context

VERSION

       version 0.43

DESCRIPTION

       This is not a subclass of Devel::Declare::Context::Simple, but it will delegate all
       default methods and extend it with some attributes and methods of its own.

       A context object will be instantiated for every keyword that is handled by
       MooseX::Declare. If handlers want to communicate with other handlers (for example handlers
       that will only be setup inside a namespace block) it must do this via the generated code.

       In addition to all the methods documented here, all methods from
       Devel::Declare::Context::Simple are available and will be delegated to an internally
       stored instance of it.

ATTRIBUTES

   caller_file
       A required "Str" containing the file the keyword was encountered in.

   preamble_code_parts
       An "ArrayRef" of "CodePart"s that will be used as preamble. A preamble in this context
       means the beginning of the generated code.

   scope_code_parts
       These parts will come before the actual body and after the "preamble_code_parts". It is an
       "ArrayRef" of "CodePart"s.

   cleanup_code_parts
       An "ArrayRef" of "CodePart"s that will not be directly inserted into the code, but instead
       be installed in a handler that will run at the end of the scope so you can do namespace
       cleanups and such.

   stack
       An "ArrayRef" that contains the stack of handlers. A keyword that was only setup inside a
       scoped block will have the blockhandler be put in the stack.

METHODS

   add_preamble_code_parts(CodePart @parts)
         Object->add_preamble_code_parts (CodeRef @parts)

       See "add_cleanup_code_parts".

   add_scope_code_parts(CodePart @parts)
         Object->add_scope_code_parts    (CodeRef @parts)

       See "add_cleanup_code_parts".

   add_cleanup_code_parts(CodePart @parts)
         Object->add_cleanup_code_parts  (CodeRef @parts)

       For these three methods please look at the corresponding *_code_parts attribute in the
       list above. These methods are merely convenience methods that allow adding entries to the
       code part containers.

   inject_code_parts_here
         True Object->inject_code_parts_here (CodePart @parts)

       Will inject the passed "CodePart"s at the current position in the code.

   peek_next_char
         Str Object->peek_next_char ()

       Will return the next char without stripping it from the stream.

   inject_code_parts
         Object->inject_code_parts (
             Bool    :$inject_cleanup_code_parts,
             CodeRef :$missing_block_handler
         )

       This will inject the code parts from the attributes above at the current position. The
       preamble and scope code parts will be inserted first. Then then call to the cleanup code
       will be injected, unless the options contain a key named "inject_cleanup_code_parts" with
       a false value.

       The "inject_if_block" method will be called if the next char is a "{" indicating a
       following block.

       If it is not a block, but a semi-colon is found and the options contained a
       "missing_block_handler" key was passed, it will be called as method on the context object
       with the code to inject and the options as arguments. All options that are not recognized
       are passed through to the "missing_block_handler". You are well advised to prefix option
       names in your extensions.

TYPES

   BlockCodePart
       An "ArrayRef" with at least one element that stringifies to either "BEGIN" or "END". The
       other parts will be stringified and used as the body for the generated block. An example
       would be this compiletime role composition:

         ['BEGIN', 'with q{ MyRole }']

   CodePart
       A part of code represented by either a "Str" or a "BlockCodePart".
