Flat Assembler 1.67.29 (Default branch)
11-16-2008
The flat assembler is a fast and efficient self-assembling 80x86 assembler for DOS, Windows, and Linux operating systems. It supports all 8086-80486/Pentium instructions with MMX, SSE, SSE2, SSE3, and 3DNow! extensions and x86-64 (both AMD64 and EM64T) instructions. It can produce output in binary, MZ, PE, COFF, or ELF format. It includes the powerful but easy-to-use macroinstruction support, and does multiple passes to optimize the instruction codes for size. The flat assembler is entirely written in assembly language. License: BSD License (revised) Changes:|

Config::MVP::Assembler(3pm) User Contributed Perl Documentation Config::MVP::Assembler(3pm) NAME
Config::MVP::Assembler - multivalue-property config-loading state machine VERSION
version 2.200002 DESCRIPTION
First, you should probably read the example of using Config::MVP. If you already know how it works, keep going. Config::MVP::Assembler is a helper for constructing a Config::MVP::Sequence object. It's a very simple state machine that lets you signal what kind of events you've encountered while reading configuration. ATTRIBUTES
sequence_class This attribute stores the name of the class to be used for the assembler's sequence. It defaults to Config::MVP::Sequence. section_class This attribute stores the name of the class to be used for sections created by the assembler. It defaults to Config::MVP::Section. sequence This is the sequence that the assembler is assembling. It defaults to a new instance of the assembler's "sequence_class". METHODS
begin_section $assembler->begin_section($package_moniker, $name); $assembler->begin_section($package_moniker); $assembler->begin_section( $package ); This method tells the assembler that it should begin work on a new section with the given identifier. If it is already working on a section, an error will be raised. See "change_section" for a method to begin a new section, ending the current one if needed. The package moniker is expanded by the "expand_package" method. The name, if not given, defaults to the package moniker. These data are used to create a new section and the section is added to the end of the sequence. If the package argument is a reference, it is used as the literal value for the package, and no expansion is performed. If it is a reference to undef, a section with no package is created. end_section $assembler->end_section; This ends the current section. If there is no current section, an exception is raised. change_section $assembler->change_section($package_moniker, $name); $assembler->change_section($package_moniker); This method calls "begin_section", first calling "end_section" if needed. add_value $assembler->add_value( $name => $value ); This method tells the assembler that it has encountered a named value and should add it to the current section. If there is no current section, an exception is raised. (If this is not the first time we've seen the name in the section and it's not a multivalue property, the section class will raise an exception on its own.) expand_package This method is passed a short identifier for a package and is expected to return the full name of the module to load and package to interrogate. By default it simply returns the name it was passed, meaning that package names must be given whole to the "change_section" method. current_section This returns the section object onto which the assembler is currently adding values. If no section has yet been created, this method will return false. TYPICAL USE
my $assembler = Config::MVP::Assembler->new; # Maybe you want a starting section: my $starting_section = $assembler->section_class->new({ name => '_' }); $assembler->sequence->add_section($section_starting); # We'll add some values, which will go to the starting section: $assembler->add_value(x => 10); $assembler->add_value(y => 20); # Change to a new section... $assembler->change_section($moniker); # ...and add values to that section. $assembler->add_value(x => 100); $assembler->add_value(y => 200); The code above creates an assembler and populates it step by step. In the end, to get values, you could do something like this: my @output; for my $section ($assembler->sequence->sections) { push @output, [ $section->name, $section->package, $section->payload ]; } When changing sections, the given section "moniker" is used for the new section name. The result of passing that moniker to the assembler's "expand_package" method is used as the section's package name. (By default, this method does nothing.) The new section's "multivalue_args" and "aliases" are determined by calling the "mvp_multivalue_args" and "mvp_aliases" methods on the package. AUTHOR
