Introduction
|
|
|
|
This PEP describes the Python Advanced Library, a collection of
|
|
high-quality and frequently-used third party extension modules.
|
|
|
|
Batteries Included Philosophy
|
|
|
|
The Python source distribution has long maintained the philosophy
|
|
of "batteries included" -- having a rich and versatile standard
|
|
library which is immediately available, without making the user
|
|
download separate packages. This gives the Python language a head
|
|
start in many projects.
|
|
|
|
However, the standard library modules aren't always the best
|
|
choices for a job. Some library modules were quick hacks
|
|
(e.g. calendar, commands), some were designed poorly and are now
|
|
near-impossible to fix (cgi), and some have been rendered obsolete
|
|
by other, more complete modules (binascii offers the same features
|
|
as the binhex, uu, base64 modules). This PEP describes a list of
|
|
third-party modules that make Python more competitive for various
|
|
application domains, forming the Python Advanced Library.
|
|
|
|
The deliverable is a set of scripts that will retrieve, build, and
|
|
install the packages for a particular application domain. The
|
|
Python Package Index now contains enough information to let
|
|
software automatically find packages and download them, so the
|
|
time is ripe to implement this.
|
|
|
|
Currently this document doesn't suggest *removing* modules from
|
|
the standard library that are superseded by a third-party module.
|
|
That's difficult to do because it entails many backward-compatibility
|
|
problems, so it's not worth bothering with now.
|
|
|
|
Please suggest additional domains of interest.
|
|
|
|
|
|
Domain: Web tasks
|
|
|
|
XML parsing: ElementTree + SAX.
|
|
|
|
URL retrieval: libcurl? other possibilities?
|
|
|
|
HTML parsing: mxTidy? HTMLParser?
|
|
|
|
Async network I/O: Twisted
|
|
|
|
RDF parser: ???
|
|
|
|
HTTP serving: ???
|
|
|
|
HTTP cookie processing: ???
|
|
|
|
Web framework: A WSGI gateway, perhaps? Paste?
|
|
|
|
Graphics: PIL, Chaco.
|
|
|
|
|
|
Domain: Scientific Programming
|
|
|

|
|
|
|
|
|
Domain: Application Development

Software covered by the GNU General Public License
|
|
|
|
Some of these third-party modules are covered by the GNU General
|
|
Public License and the GNU Lesser General Public License.
|
|
Providing a script to download and install such packages, or even
|
|
assembling all these packages into a single tarball or CD-ROM,
|
|
shouldn't cause any difficulties with the GPL, under the "mere
|
|
aggregation" clause of the license.
|
|
|
|
|
|
Open Issues
|
|
|
|
What other application domains are important?
|
|
|
|
Should this just be a set of Ubuntu or Debian packages? Compiling
|
|
things such as PyGame can be very complicated and may be too
|
|
difficult to automate.
