ANN: EmPy 3.3.2 released (Python 3.x compatibility)

[Erik Max Francis]

Summary

     A powerful and robust templating system for Python.


Overview

     EmPy is a system for embedding Python expressions and statements
     in template text; it takes an EmPy source file, processes it, and
     produces output.  This is accomplished via expansions, which are
     special signals to the EmPy system and are set off by a special
     prefix (by default the at sign, '@').  EmPy can expand arbitrary
     Python expressions and statements in this way, as well as a
     variety of special forms.  Textual data not explicitly delimited
     in this way is sent unaffected to the output, allowing Python to
     be used in effect as a markup language.  Also supported are
     callbacks via hooks, recording and playback via diversions, and
     dynamic, chainable filters.  The system is highly configurable via
     command line options and embedded commands.

     Expressions are embedded in text with the '@(...)' notation;
     variations include conditional expressions with '@(...?...!...)'
     and the ability to handle thrown exceptions with '@(...$...)'.  As
     a shortcut, simple variables and expressions can be abbreviated as
     '@variable', '@object.attribute', '@function(arguments)',
     '@sequence' [index], and combinations.  Full-fledged statements
     are embedded with '@{...}'.  Control flow in terms of conditional
     or repeated expansion is available with '@[...]'.  A '@' followed
     by a whitespace character (including a newline) expands to
     nothing, allowing string concatenations and line continuations.
     Comments are indicated with '@#' and consume the rest of the line,
     up to and including the trailing newline.  '@%' indicate
     "significators," which are special forms of variable assignment
     intended to specify per-file identification information in a
     format which is easy to parse externally.  Context name and line
     number changes can be done with '@?' and '@!' respectively.
     '@<...>' markups are customizeable by the user and can be used for
     any desired purpose.  Escape sequences analogous to those in C can
     be specified with '@\...', and finally a '@@' sequence expands to
     a single literal at sign.
