The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Perl #include (hack)

Asked by tomaugerdotcom in Perl Programming Language

I'm revivifying legacy code but don't have time to refactor it, so I'm looking for a hack. Current code is one single (huge) script using strict that declares all its "global" variables using "my". I am unwilling at this point to change this.

I need a way to modularize the code, while maintaining the lexical scope to the main:: namespace.

In short, I want a pre-compile "include" as opposed to a runtime "require" or a compile-time "use", because those all do not have visibility into the main namespace, or at least AFAIK.

I thought I could get there with do "$file" or eval "cat $file" but the do form still doesn't see my main:: namespace variables and the eval "cat $file" simply fails silently and I don't know why.

I realize that this is a hack, and you will be inclined to say "use packages, proper namespaces and modules" but I don't have time.

I'm sure there's a way to simply include code from an external file as though it were directly injected into the current script. What am I missing? Ozo - I'm expecting you to weigh in here :)
