Extended attributes for Python is a Python module that can manipulate extended attributes in filesystems that support them.

Extended Python Debugger is a complete debugger for Python than the stock pdb.py debugger.

It supports a "restart" command and stack traces that show fewer ?s and give better information for exec statements.

Stepping/nexting skips over method/function "defs". It tries to follow gdbs command set unless there is good reason not to.

Text::MacroScript is a macro pre-processor with embedded perl capability.

SYNOPSIS

use Text::MacroScript ;

# new() for macro processing

my $Macro = Text::MacroScript->new ;
while( ) {
print $Macro->expand( $_ ) if $_ ;
}

# Canonical use (the filename improves error messages):
my $Macro = Text::MacroScript->new ;
while( ) {
print $Macro->expand( $_, $ARGV ) if $_ ;
}

# new() for embedded macro processing

my $Macro = Text::MacroScript->new( -embedded => 1 ) ;
# Delimiters default to
# or
my $Macro = Text::MacroScript->new( -opendelim => [[, -closedelim => ]] ) ;
while( ) {
print $Macro->expand_delimited( $_, $ARGV ) if $_ ;
}

# Create a macro object and create initial macros/scripts from the file(s)
# given:
my $Macro = Text::MacroScript->new(
-file => [ local.macro, ~/.macro/global.macro ]
) ;

# Create a macro object and create initial macros/scripts from the
# definition(s) given:
my $Macro = Text::MacroScript->new(
-macro => [
[ MAX_INT => 32767 ],
],
-script => [
[ DHM2S =>
[
my $s = (#0*24*60*60)+(#1*60*60)+(#2*60) ;
"#0 days, #1 hrs, #2 mins = $s secs"
],
],
-variable => [ *MARKER* => 0 ],
) ;

# We may of course use any combination of the options.

my $Macro = Text::MacroScript->new( -comment => 1 ) ; # Create the %%[] macro.

# define()

$Macro->define( -macro, $macroname, $macrobody ) ;

$Macro->define( -script, $scriptname, $scriptbody ) ;

$Macro->define( -variable, $variablename, $variablebody ) ;

# undefine()

$Macro->undefine( -macro, $macroname ) ;

$Macro->undefine( -script, $scriptname ) ;

$Macro->undefine( -variable, $variablename ) ;

# undefine_all()

$Macro->undefine( -macro ) ;

$Macro->undefine( -script ) ;

$Macro->undefine( -variable ) ;

# list()

@macros = $Macro->list( -macro ) ;
@macros = $Macro->list( -macro, -namesonly ) ;

@scripts = $Macro->list( -script ) ;
@scripts = $Macro->list( -script, -namesonly ) ;

@variables = $Macro->list( -variable ) ;
@variables = $Macro->list( -variable, -namesonly ) ;

# load_file() - always treats the contents as within delimiters if we are
# doing embedded processing.

$Macro->load_file( $filename ) ;

# expand_file() - calls expand_embedded() if we are doing embedded
# processing otherwise calls expand().

$Macro->expand_file( $filename ) ;
@expanded = $Macro->expand_file( $filename ) ;


# expand()

$expanded = $Macro->expand( $unexpanded ) ;
$expanded = $Macro->expand( $unexpanded, $filename ) ;

# expand_embedded()

$expanded = $Macro->expand_embedded( $unexpanded ) ;
$expanded = $Macro->expand_embedded( $unexpanded, $filename ) ;

This bundle also includes the macro and macrodir scripts which allows us to expand macros without having to use/understand Text::MacroScript.pm, although you will have to learn the handful of macro commands available and which are documented here and in macro. macro provides more documentation on the embedded approach.

The macroutil.pl library supplied provides some functions which you may choose to use in HTML work for example.

SPYCE is a server-side language that supports simple and efficient Python-based dynamic HTML generation, otherwise called Python Server Pages (PSP).

Those who are familiar with JSP, PHP, or ASP and like Python, should have a look at Spyce. Its modular design makes it very flexible and extensible. Spyce - Python Server Pages can also be used as a command-line utility for static text pre-processing or as a web-server proxy.

The supported adapters are:

* Fast CGI:The default Spyce integration with Apache is acheived via FastCGI, a CGI-like interface that is relatively fast, because it does not incur the large process startup overhead on each request.

* mod_python: If you really must have the fastest Spyce implementation (see the performance numbers), it is currently through an Apache module called mod_python. Spyce has been tested with mod_python version 2.7.6 (and version 3.0.3 with apache 2.0.37). You can try to find some mod_python rpms here, but in general one must compile mod_python from sources. The reason for this is because mod_python links with the Python library it finds on your system at compile time. Thus, even if you have the correct Python version installed on your system, mod_python will be using the Python library version on the system where it was compiled. Also, note that mod_python (or rather Apache) needs a Python that has been compiled without threading, so you may need to recompile Python as well for this reason. The process is not very difficult (just the usual: ./configure; make; make install dance), but hopefully someone will suggest a better route in time. In any case, make sure you can first get mod_python running on your system, if that is that is your chosen Apache integration route.

* Web server: Another fast alternative is to serve Spyce files via a proxy. This involves running Spyce in web-server mode, and configuring the main web server to forward the appropriate requests. The built-in Spyce web server can also be used to serve requests directly, but this is highly discouraged for production environments.

* CGI: Failing these alternatives you can always process requests via regular CGI, but this alternative is the slowest option and is intended primarily for those who do not have much control over their web environments.

* Command line: Lastly, one can use Spyce as a command-line tool for pre-processing Spyce pages and creating static HTML files.

Thousand Parsec Python Text client works with any computer which has Python and the python network library installed. This client can only be checked out of CVS at the moment.

Thousand Parsec is a framework for turn based space empire building games.

Some examples of games which Thousand Parsec draws ideas from are, Stars!, VGA Planets, Master of Orion and Galactic Civilizations. These games are often called 4 Xs from the main phases found in the games, eXplore, eXpand, eXploit and eXterminate. If you havent heard of them, other games which are a bit similar include, Civilisation, Heros of Might and Magic and Starcraft.

Thousand Parsec includes everything you need to play any of the currently running games,
set up your own game using already designed games, and building your own space empire building game.

Gst-Python provides Python bindings for the GStreamer project. These bindings provide access to almost all of the GStreamer C API through an object oriented Python API.

CORBA-Python is a package supplies the following tools : idl2py : IDL compiler to Python.

idl2pyemb : IDL compiler to Python embedded with C idl2pyext : IDL compiler to Python extension with C idl2pycli : RPC-GIOP client stub generator idl2pysrv : RPC-GIOP server skeleton generator
