ANN: empy 1.1 -- Embed Python in template text as markup

[Erik Max Francis]

Summary

    empy (formerly Munch) is a system for embedding Python expressions
    and statements in template text (or any other unexecuted content);
    it takes source files, processes them, and produces output.  These
    are done via expansions, which are snippets of Python code delimited
    by character sequences involving a special prefix (by default the at
    sign, '@'), and are substituted in the output with the return
    value (for expressions) or with any in-Python printing to stdout
    that takes place (for both expressions and statements).  If the
    value of an evaluated expression is None, nothing is expanded
    (that is, it acts like the interactive Python interpreter).
    Textual data not explicitly delimited in this way is sent
    unaffected to the output file, allowing Python to be used in
    effect as a markup language.  Explicit expansion, or inclusion of
    other files to be expanded, is possible.  Also supported are
    m4-style diversions, where output can be systematically deferred
    and recalled.

    Expressions are embedded in text with the '@(...)' notation; as a
    shortcut, simple variables and expressions can be abbreviated as
    '@variable', '@object.attribute', '@array' [index],
    '@function(arguments)', or variations.  Full-fledged statements
    are embedded with '@{...}'.  A '@' followed by a whitespace
    character (including a newline) expands to nothing, allowing line
    continuations.  Comments are indicated with '@#' and consume the
    rest of the line, including the trailing newline.  A '@@' sequence
    expands to a single literal at sign.


Getting the software

    The software is available in a tarball here:
    http://www.alcyone.com/pyos/empy/empy-1.0.tar.gz.

    The official URL for this Web site is
    http://www.alcyone.com/pyos/empy/.


What's new

    Added options for fully buffering output (including file opens),
    executing commands through the command line; some documentation
    errors fixed.
