-:mod:`multifile` --- Support for files containing distinct parts
-================================================================
-
-.. module:: multifile
- :synopsis: Support for reading files which contain distinct parts, such as some MIME data.
- :deprecated:
-.. sectionauthor:: Eric S. Raymond <esr@snark.thyrsus.com>
-
-
-.. deprecated:: 2.5
- The :mod:`email` package should be used in preference to the :mod:`multifile`
- module. This module is present only to maintain backward compatibility.
-
-The :class:`MultiFile` object enables you to treat sections of a text file as
-file-like input objects, with ``''`` being returned by :meth:`readline` when a
-given delimiter pattern is encountered. The defaults of this class are designed
-to make it useful for parsing MIME multipart messages, but by subclassing it and
-overriding methods it can be easily adapted for more general use.
-
-
-.. class:: MultiFile(fp[, seekable])
-
- Create a multi-file. You must instantiate this class with an input object
- argument for the :class:`MultiFile` instance to get lines from, such as a file
- object returned by :func:`open`.
-
- :class:`MultiFile` only ever looks at the input object's :meth:`readline`,
- :meth:`seek` and :meth:`tell` methods, and the latter two are only needed if you
- want random access to the individual MIME parts. To use :class:`MultiFile` on a
- non-seekable stream object, set the optional *seekable* argument to false; this
- will prevent using the input object's :meth:`seek` and :meth:`tell` methods.
-
-It will be useful to know that in :class:`MultiFile`'s view of the world, text
-is composed of three kinds of lines: data, section-dividers, and end-markers.
-MultiFile is designed to support parsing of messages that may have multiple
-nested message parts, each with its own pattern for section-divider and
-end-marker lines.
-
-
-.. seealso::
-
- Module :mod:`email`
- Comprehensive email handling package; supersedes the :mod:`multifile` module.

-MultiFile Objects
------------------
-
-A :class:`MultiFile` instance has the following methods:
-
-
-.. method:: MultiFile.readline(str)
-
- Read a line. If the line is data (not a section-divider or end-marker or real
- EOF) return it. If the line matches the most-recently-stacked boundary, return
- ``''`` and set ``self.last`` to 1 or 0 according as the match is or is not an
- end-marker. If the line matches any other stacked boundary, raise an error. On
- encountering end-of-file on the underlying stream object, the method raises
- :exc:`Error` unless all boundaries have been popped.
-
-
-.. method:: MultiFile.readlines(str)
-
- Return all lines remaining in this part as a list of strings.
-
-
-.. method:: MultiFile.read()
-
- Read all lines, up to the next section. Return them as a single (multiline)
- string. Note that this doesn't take a size argument!
-
-
-.. method:: MultiFile.seek(pos[, whence])
-
- Seek. Seek indices are relative to the start of the current section. The *pos*
- and *whence* arguments are interpreted as for a file seek.
-
-
-.. method:: MultiFile.tell()
-
- Return the file position relative to the start of the current section.
-
-
-.. method:: MultiFile.next()
-
- Skip lines to the next section (that is, read lines until a section-divider or
- end-marker has been consumed). Return true if there is such a section, false if
- an end-marker is seen. Re-enable the most-recently-pushed boundary.
-
-
-.. method:: MultiFile.is_data(str)
-
- Return true if *str* is data and false if it might be a section boundary. As
- written, it tests for a prefix other than ``'-``\ ``-'`` at start of line (which
- all MIME boundaries have) but it is declared so it can be overridden in derived
- classes.
-
- Note that this test is used intended as a fast guard for the real boundary
- tests; if it always returns false it will merely slow processing, not cause it
- to fail.
-
-
-.. method:: MultiFile.push(str)
-
- Push a boundary string. When a decorated version of this boundary is found as
- an input line, it will be interpreted as a section-divider or end-marker
- (depending on the decoration, see :rfc:`2045`). All subsequent reads will
- return the empty string to indicate end-of-file, until a call to :meth:`pop`
- removes the boundary a or :meth:`next` call reenables it.
-
- It is possible to push more than one boundary. Encountering the
- most-recently-pushed boundary will return EOF; encountering any other
- boundary will raise an error.
-
-
-.. method:: MultiFile.pop()
-
- Pop a section boundary. This boundary will no longer be interpreted as EOF.
-
-
-.. method:: MultiFile.section_divider(str)
-
- Turn a boundary into a section-divider line. By default, this method
- prepends ``'--'`` (which MIME section boundaries have) but it is declared so
- it can be overridden in derived classes. This method need not append LF or
- CR-LF, as comparison with the result ignores trailing whitespace.
-
-
-.. method:: MultiFile.end_marker(str)
-
- Turn a boundary string into an end-marker line. By default, this method
- prepends ``'--'`` and appends ``'--'`` (like a MIME-multipart end-of-message
- marker) but it is declared so it can be overridden in derived classes. This
- method need not append LF or CR-LF, as comparison with the result ignores
- trailing whitespace.
-
-Finally, :class:`MultiFile` instances have two public instance variables:
-
-
-.. attribute:: MultiFile.level
-
- Nesting depth of the current part.
-
-
-.. attribute:: MultiFile.last
-
- True if the last end-of-file was for an end-of-message marker.
