What's new in this release?
|
||||
---------------------------
|
||||
|
||||
Ehm, I'll be more complete later. Som highlights: I've completed the
|
||||
Grand Renaming. It's much faster (almost twice for pystone.py -- see
|
||||
Tools/scripts.) There's an assert statement, and a -O option that
|
||||
squeezes SET_LINENO instructions and if __debug__ code. It's much
|
||||
smarter (only on Unix, so far) about the initial value for sys.path.
|
||||
See the usage message (python -h). There's an explicit structure that
|
||||
maintains all per-thread globals.
|
||||
Too much has changed to list it all; I'll be more complete later.
|
||||
|
||||
Unfinished projects: documentation; multiple independent interpreters;
|
||||
better embedding support; more Windows support.
|
||||
The most important changes since Python 1.4 include:
|
||||
|
||||
- Many previously undocumented modules are now documented; some are
|
||||
now officially obsolete or deprecated.
|
||||
|
||||
- It's much faster (almost twice for pystone.py -- see Tools/scripts.)
|
||||
|
||||
- There's an assert statement.
|
||||
|
||||
- There's a -O option that removes SET_LINENO instructions and code
|
||||
prefixed with ``if __debug__: ...''.
|
||||
|
||||
- It's much smarter about the initial value for sys.path; you can
|
||||
control it easier using $PYTHONHOME (see the usage message, e.g. try
|
||||
``python -h'').
|
||||
|
||||
- The Grand Renaming is completed: all linker-visible symbols defined
|
||||
by Python now have a "Py" or "_Py" prefix, and the same is true for
|
||||
most macros and typedefs.
|
||||
|
||||
- The build strategy now uses a single library (libpython1.5.a) which
|
||||
contains everything except for the main() entry point. This makes
|
||||
life much easier for applications that want to embed Python.
|
||||
|
||||
- There is also much better support for embedding Python in
|
||||
applications that use threads.
|
||||
|
||||
- Unfinished projects: documentation; multiple independent
|
||||
interpreters; more Windows support.

--with-readline: You can use the GNU readline library to improve the

interactive user interface. This gives you line editing and

readline is a standard part of your system (it is on Linux),

from its home site:

ftp://slc2.ins.cwru.edu/pub/dist/readline-2.0.tar.gz (or

recommended).

Pass the Python configure script the option

pathname of the directory where you've built the readline

readline library are in the FAQ (file Misc/FAQ).

--with-readline: This option is no longer supported. To use GNU

readline, enable module "readline" in the Modules/Setup file.
