parl - Binary PAR Loader


(Please see pp for convenient ways to make self-contained executables, scripts or PAR archives from perl programs.)

To use Hello.pm from ./foo.par:

    % parl -A./foo.par -MHello 
    % parl -A./foo -MHello      # the .par part is optional

Same thing, but search foo.par in the @INC;

    % parl -Ifoo.par -MHello 
    % parl -Ifoo -MHello        # ditto

Run test.pl or script/test.pl from foo.par:

    % parl foo.par test.pl      # looks for 'main.pl' by default,
                                # otherwise run 'test.pl' 

To make a self-containing executable containing a PAR file :

    % parl -O./foo foo.par
    % ./foo test.pl             # same as above

To embed the necessary non-core modules and shared objects for PAR's execution (like Zlib, IO, Cwd, etc), use the -b flag:

    % parl -b -O./foo foo.par
    % ./foo test.pl             # runs anywhere with core modules installed

If you also wish to embed core modules along, use the -B flag instead:

    % parl -B -O./foo foo.par
    % ./foo test.pl             # runs anywhere with the perl interpreter

This is particularly useful when making stand-alone binary executables; see pp for details.


This stand-alone command offers roughly the same feature as perl -MPAR, except that it takes the pre-loaded .par files via -Afoo.par instead of -MPAR=foo.par.

You can use it to run .par files:

    # runs script/run.pl in archive, uses its lib/* as libraries
    % parl myapp.par run.pl     # runs run.pl or script/run.pl in myapp.par
    % parl otherapp.pl          # also runs normal perl scripts

However, if the .par archive contains either main.pl or script/main.pl, it is used instead:

    % parl myapp.par run.pl     # runs main.pl, with 'run.pl' as @ARGV

Finally, as an alternative to Perl2exe or PerlApp, the -O option makes a stand-alone binary from a PAR file:

    % parl -B -Omyapp myapp.par
    % ./myapp                   # run it anywhere without perl binaries
    % ./myapp -Omyap2 myapp.par # makes a ./myap2, identical to ./myapp
    % ./myapp -Omyap3 myap3.par # makes another app with different PAR

For an explanation of stand-alone executable format, please see par.pl.
