NAME
parl - Binary PAR Loader
SYNOPSIS
(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.
DESCRIPTION
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, the -O
option makes a stand-alone binary executable from a PAR file:
% parl -B -Omyapp myapp.par
% ./myapp # run it anywhere without perl binaries
With the --par-options
flag, generated binaries can act as parl
to pack new binaries:
% ./myapp --par-options -Omyap2 myapp.par # identical to ./myapp
% ./myapp --par-options -Omyap3 myap3.par # now with different PAR
For an explanation of stand-alone executable format, please see par.pl.
