    This document describes version 0.182 of Module::FatPack (from Perl
    distribution Module-FatPack), released on 2020-01-03.


     fatpack_modules(%args) -> [status, msg, payload, meta]

    Generate source code that contains fatpacked modules.

    This routine provides the same core technique employed by
    "App::FatPacker" (which is putting modules' source code inside Perl
    variables and loading them on-demand via require hook) without all the
    other stuffs. All you need is supply the names of modules (or the
    modules' source code themselves) and you'll get the output in a file or

    This function is not exported by default, but exportable.

    Arguments ('*' denotes required arguments):

    *   add_begin_block => *bool*

        Surround the code inside BEGIN { }.

    *   assume_strict => *bool* (default: 0)

        Assume code runs under stricture.

    *   line_prefix => *str*

    *   module_names => *array[str]*

        Module names to search.

    *   module_srcs => *hash*

        Module source codes (a hash, keys are module names).

    *   output => *str*

        Output filename.

    *   overwrite => *bool* (default: 0)

        Whether to overwrite output if previously exists.

    *   pm => *bool*

        Make code suitable to put inside .pm file instead of script.

        This setting adjusts the code so it is suitable to put one or
        several instances of the code inside one or more .pm files. Also
        sets default for --line-prefix '#' --no-add-begin-block

    *   postamble => *str*

        Perl source code to add after the fatpack code.

    *   preamble => *str*

        Perl source code to add before the fatpack code.

    *   put_hook_at_the_end => *bool*

        Put the require hook at the end of @INC using "push" instead of at
        the front using "unshift".

    *   stripper => *bool* (default: 0)

        Whether to strip included modules using Perl::Stripper.

    *   stripper_comment => *bool* (default: 1)

        Set strip_comment=1 (strip comments) in Perl::Stripper.

    *   stripper_log => *bool* (default: 0)

        Set strip_log=1 (strip log statements) in Perl::Stripper.

    *   stripper_maintain_linum => *bool* (default: 0)

        Set maintain_linum=1 in Perl::Stripper.

    *   stripper_pod => *bool* (default: 1)

        Set strip_pod=1 (strip POD) in Perl::Stripper.

    *   stripper_ws => *bool* (default: 1)

        Set strip_ws=1 (strip whitespace) in Perl::Stripper.

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra

    Return value: (any)

    App::FatPacker, the original implementation.

    App::depak for more options e.g. use various tracing methods, etc.

    fatpack-modules, CLI for "fatpack_modules"

    Module::DataPack, which implements an alternative technique to
    fatpacking called datapacking. The modules are embedded not in a
    variable in Perl code (which still needs to be parsed by perl), but
    instead in the __DATA__ section (whch does not need to be parsed by
    perl). A script with lots of modules to embed can benefit from
    datapacking technique and lower its startup overhead.
