FUNCTIONS

detect_getopt_long_subcommand_script(%args) -> [status, msg, result, meta]

Detect whether a file is a Getopt::Long::Subcommand-based CLI script.

The criteria are:

• the file must exist and readable;

• (optional, if include_noexec is false) file must have its executable mode bit set;

• content must start with a shebang #!;

• either: must be perl script (shebang line contains 'perl') and must contain something like use Getopt::Long::Subcommand;

This function is not exported.

Arguments ('*' denotes required arguments):

• filename => str

  Path to file to be checked.

• include_noexec => bool (default: 1)

  Include scripts that do not have +x mode bit set.

• string => buf

  Path to file to be checked.

  Either file or string must be specified.

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 (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
