NAME
    Setup::File::TextFragment - Insert/delete text fragment in a file (with
    undo support)

VERSION
    This document describes version 0.06 of Setup::File::TextFragment (from
    Perl distribution Setup-File-TextFragment), released on 2017-07-10.

FUNCTIONS
  setup_text_fragment
    Usage:

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

    Insert/delete text fragment in a file (with undo support).

    On do, will insert fragment to file (or delete, if "should_exist" is set
    to false). On undo, will restore old file.

    Unfixable state: file does not exist or not a regular file (directory
    and symlink included).

    Fixed state: file exists, fragment already exists and with the same
    content (if "should_exist" is true) or fragment already does not exist
    (if "should_exist" is false).

    Fixable state: file exists, fragment doesn't exist or payload is not the
    same (if "should_exist" is true) or fragment still exists (if
    "should_exist" is false).

    This function is not exported by default, but exportable.

    This function is idempotent (repeated invocations with same arguments
    has the same effect as single invocation). This function supports
    transactions.

    Arguments ('*' denotes required arguments):

    *   attrs => *hash*

        Fragment attributes (only for inserting new fragment), passed to
        Text::Fragment.
