FUNCTIONS

depak

Usage:

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

Pack your dependencies onto your script file.

This function is not exported.

Arguments ('*' denotes required arguments):

  • allow_xs => array[str]

  • args => array[str]

    Script arguments.

    Will be used when running your script, e.g. when trace_method is fatpacker or require. For example, if your script requires three arguments: --foo, 2, "bar baz" then you can either use:

     % depak script output --args --foo --args 2 --args "bar baz"

    or:

     % depak script output --args-json '["--foo",2,"bar baz"]'
  • debug_keep_tempdir => bool

    Keep temporary directory for debugging.

  • exclude_core => bool (default: 1)

    Whether to exclude core modules.

  • exclude_dist => array[str]

    Exclude all modules of dist.

    Just like the exclude option, but will exclude module as well as other modules from the same distribution. Module name must be the main module of the distribution. Will determine other modules from the .packlist file.

  • exclude_list => str

    Exclude modules from a list in a file.

  • exclude_module => array[str]

    Modules to exclude.

    When you don't want to include a module, specify it here.

  • exclude_pattern => array[str]

    Regex patterns of modules to exclude.

    When you don't want to include a pattern of modules, specify it here.

  • exclude_prereq => array[str]

    This option can be used to express that script will depend on a specified module, instead of including it packed. The prereq-ed module, as well as other modules in the same distribution, as well as its prereqs and so on recursively, will be excluded from packing as well.

    This option can be used to express dependency to an XS module, since XS modules cannot be packed.

    To query dependencies, a local CPAN index is used for querying speed. Thus, this option requires that lcpan is installed and a fairly recent lcpan index is available.

  • include_dir => array[str]

    Include extra modules under directories.

  • include_dist => array[str]

    Include all modules of dist.

    Just like the include option, but will include module as well as other modules from the same distribution. Module name must be the main module of the distribution. Will determine other modules from the .packlist file.

  • include_list => str

    Include extra modules from a list in a file.

  • include_module => array[str]

    Include extra modules.

    When the tracing process fails to include a required module, you can add it here.

  • include_prereq => array[str]

    This option can be used to include a module, as well as other modules in the same distribution as that module, as well as the distribution's recursive dependencies, for packing. Dependencies will be searched using a local CPAN index. This is a convenient alternative to tracing a module. So you might want to use this option together with setting trace_method to none.

    This option requires that lcpan is installed and a fairly recent lcpan index is available.

  • input_file => str (default: "-")

    Path to input file (script to be packed).

    - (or if unspecified) means to take from standard input (internally, a temporary file will be created to handle this).

  • multiple_runs => array[hash]

    Pass to tracepm.

  • output_file => str (default: "-")

    Path to output file.

    - (or if unspecified) means to output to stdout.

  • overwrite => bool (default: 0)

    Whether to overwrite output if previously exists.

  • pack_method => str (default: "fatpack")

    Packing method to use.

    Either fatpack (the default) or datapack. Fatpack puts packed modules inside Perl variables and load them via require hook. Datapack puts packed modules in DATA section. For more details about each method, please consult Module::FatPack and Module::DataPack.

    One thing to remember is, with datapack, your script cannot load modules during compile-time (use): all modules must be loaded during run-time (require) when data section is already available. Also, your script currently cannot contain data section of its own.

  • perl_version => str

    Perl version to target, defaults to current running version.

    This is for determining which modules are considered core and should be skipped by default (when exclude_core option is enabled). Different perl versions have different sets of core modules as well as different versions of the modules.

  • put_hook_at_the_end => bool

    Prefer modules from other sources (filesystem) first.

    Normally, the fatpack or datapack require hook will be put at the front of @INC. If this option is set to true, the require hook will be put at the end. This means Perl will search modules from the regular sources (filesystem) first. This is useful for example if you want your application to use the possibly newer version of modules on the filesystem before using the packed version as the fallback when some modules are not installed.

  • shebang => str (default: "/usr/bin/perl")

    Set shebang line/path.

  • skip_not_found => bool

    Instead of dying, skip when module to add is not found.

    This option is useful when you use include_prereq, because modules without its own .pm files will also be included (CPAN indexes packages, including those that do not have their own .pm files).

    By default, this option is turned off unless when you use include_prereq where this option is by default turned on. You can of course override the default by explicitly specify this option.

  • squish => bool (default: 0)

    Whether to squish included modules using Perl::Squish.

  • strip => bool (default: 0)

    Whether to strip included modules using Perl::Strip.

  • 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.

  • test => bool

    Test the resulting output.

    Testing is done by running the resulting packed script with perl. To test, at least one test case is required (see --test-case-json). Test cases specify what arguments to give to program, what exit code we expect, and what the output should contain.

  • test_cases => array[hash]

    Example case:

     {"args":["--help"], "exit_code":0, "perl_args":["-Mlib::core::only"], "output_like":"Usage:"}
  • trace_extra_opts => hash

    Pass more options to `App::tracepm`.

  • trace_method => str (default: "fatpacker")

    Which method to use to trace dependencies.

    The default is fatpacker, which is the same as what fatpack trace does. Different tracing methods have different pro's and con's, one method might detect required modules that another method does not, and vice versa. There are several methods available, please see App::tracepm for more details.

    A special value of none is also provided. If this is selected, then depak will not perform any tracing. Usually used in conjunction with --include-from.

  • use => array[str]

    Additional modules to "use".

    Will be passed to the tracer. Will currently only affect the fatpacker and require methods (because those methods actually run your script).

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 information.

Return value: (any)
