in reply to Perl 5 Optimizing Compiler

Welcome Will_the_Chill,

From my observations, Perl gets better with each new version, and if you use Perl's strengths, you can leave many 'off-the-shelf' 'C' programs in the dust.

But, I would love to see a Perl compiler, but not for speed or concealing the code from hackers, but for code security, revision control and simplicity of deployment. ( and probably a few more. )

Before Perl, I used 'C' and 'uxbasic', a 'compiler' that mimicked the Z80 based 'oasis/theos' basic from the '80s but could run on most AIX/Unix systems. It could be run from source (BASIC), from an interpreter compiled code (BASICOBJ), and from pseudo compiled code (BASICCOM). As a developer you tested with the first 2 modes and then shipped the final version as the pseudo compiled code (think bytecode). And guess what, if the run time version of 'uxbasic' was installed, the code you shipped worked.

Now I'm not comparing this '80s code to Perl, but that concept of distributing code would improve the user experience with Perl. Why?

Since the '80s, I have sold and supported software for companies, the majority of which have 10 to 100 employees. They also have 1 or more people who have used Perl to print "Hello World". Since I started shipping Perl modules, I've had some of the funniest (maybe tragic) updates to my software. For example:

  • One site removed the rounding on invoices to make it faster. Why? "...don't need it for 2 decimal places..." So after 400+ invoices are incorrect, the president calls and says '...your lousy software screwed up, everyone told me to go with a 'C' or 'VB' or ... solution... FIX IT"
  • One site changed one screen, and then removed 'use strict' so the code would compile.
  • Another changed the copyright notice, and it stopped working. The 'expert' couldn't find the problem, and wanted us to fix it.

If you work in an environment where you control everything, then you wouldn't understand the 'user' frustrations from 'brilliant' coders.

So why can't Perl have a '-Compile' like the '-cw' compiler flags that produces a bitecode that can be shipped and run. Every one knows that someone that wants to get the code can, but the casual 'expert' would be deterred by '...It looks like 'C' to me!'

Thank you

    If you don't want "customers" diddling the code, you can use PerlApp/CavaPackager/PAR (with filters, crypto/whitespace, even used to be a B::Bytecode filter )

There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

        You're wrong CountZero and rude.
