NAME

CodeGen::Protection::Format::HTML - Safely rewrite parts of HTML documents

VERSION

version 0.06

SYNOPSIS

    my $rewrite = CodeGen::Protection::Format::HTML->new(
        protected_code => $text,
    );
    say $rewrite->rewritten;

    my $rewrite = CodeGen::Protection::Format::HTML->new(
        existing_code => $existing_code,
        protected_code => $protected_code,
    );
    say $rewrite->rewritten;

DESCRIPTION

This module allows you to do a safe partial rewrite of documents. If you're familiar with DBIx::Class::Schema::Loader, you probably know the basic concept.

Note that this code is designed for HTML documents and is not very configurable.

In short, we wrap your "protected" (protected_code) HTML code in start and end comments, with checksums for the code:

    #<<< CodeGen::Protection::Format::HTML 0.01. Do not touch any code between this and the end comment. Checksum: fa97a021bd70bf3b9fa3e52f203f2660
    
    # protected HTML goes here

    #>>> CodeGen::Protection::Format::HTML 0.01. Do not touch any code between this and the start comment. Checksum: fa97a021bd70bf3b9fa3e52f203f2660

If existing_code is provided, this module removes the code between the old code's start and end markers and replaces it with the protected_code. If the code between the start and end markers has been altered, it will no longer match the checksums and rewriting the code will fail.
