Tobia, any update on progress of script compilation?

It seems, given the current state of non-compiled scripts (see bug
discussion: <[perl #127330] [SLOW] 10_000 lines with ｢say ‘a’;｣ take
16 seconds to run>), a compilation capability would give Perl 6
advocacy a boost while other optimizations mentioned by Liz in the bug
discussion continue.

Could auto-compilation be an option (and an auto-recompile based on
the source script's hash)?

Thanks.

Cheers!

A large part of Perl 6 is written in Perl 6.  This currently consists of about 
28000 lines of code.  This code is pre-compiled, so that it can be loaded in 
just over .1 second.

This pre-compilation is a normal part of the install process of *any* module if 
you’re using either rakudobrew or panda.

The compiled version differs by VM backend.  If JVM is the backend, the 
compiled version is stored as a standard .jar.  On MoarVM, it has the extension 
.moarvm, and has its own version.

The compiled version is also, one can say, “statically linked” as it were to 
the version of Rakudo that compiled it.  So if you upgrade rakudo, new compiled 
versions need to be created.  This is also part of rakudobrew and the panda 
rebootstrap process.


Hope this answers your question.

I found some discussion of such a capability on the Perl Mongers' site but
haven't found anything official yet in the Synopses.

But I did find there an option that might do something related:
--output-format (which is implementation defined).  However, I do not see
that option in Rakudo Perl 6.

We precompile modules using a command line option like in: 'perl6
--target=mbc --output=foo.pm.moarvm'.
Though, since this is for modules, only this incantation will work:
'perl6 -I. -Mfoo -e1'

We are working on creating executables such as 'foo.exe' from a given
Perl 6 script, though I expect that this takes a few months before this
feature lands.
These executable would contain the Perl 6 interpreter, and the
precompiled script in one file.

Thanks Liz and Tobias!
