Announce : PLY-3.0
by David Beazley 07 Feb '09

07 Feb '09

February 6, 2009 Announcing : PLY-3.0 (Python Lex-Yacc) http://www.dabeaz.com/ply I'm pleased to announce a significant new update to PLY---a 100% Python implementation of the common parsing tools lex and yacc. PLY-3.0 adds compatibility for Python 2.6 and 3.0, provides some new customization options, and cleans up a lot of internal implementation details. If you are new to PLY, here are a few highlights: - PLY is closely modeled after traditional lex/yacc. If you know how to use these or similar tools in other languages, you will find PLY to be comparable. - PLY provides very extensive error reporting and diagnostic information to assist in parser construction. The original implementation was developed for instructional purposes. As a result, the system tries to identify the most common types of errors made by novice users. - PLY provides full support for empty productions, error recovery, precedence rules, and ambiguous grammars. - Parsing is based on LR-parsing which is fast, memory efficient, better suited to large grammars, and which has a number of nice properties when dealing with syntax errors and other parsing problems. Currently, PLY can build its parsing tables using either SLR or LALR(1) algorithms. More information about PLY can be obtained on the PLY webpage at: http://www.dabeaz.com/ply PLY is freely available and is licensed under the terms of the Lesser GNU Public License (LGPL). Cheers, David Beazley (http://www.dabeaz.com)

MySQLdb-1.2.3 beta 1 released
by Andy Dustman 05 Feb '09

05 Feb '09

After almost two years of not so much going on, I've released MySQLdb-1.2.3 beta 1, the first of a couple of betas before PyCon 2009. Highlights: * Compatible with Python-2.6 (but not yet 3.0) * Fixed some parameter substitution problems * Fixed some build problems on certain platforms * Other stuff I don't remember Eggs are available at the usual place for Python-2.5 and 2.6 on i386, i.e. use ez_install. This is a beta, but it should actually work better than 1.2.2, if you were having problems. Otherwise there are no new features yet. However, It is a test release, so if you do try it, be prepared to report bugs. Patches/tests appreciated. I'm planning a sprint for PyCon 2009 though due to personal commitments, I may only be able to stay for one day. If all the 1.2 bugs are sorted out, I might work more on 1.3 (the current SVN trunk, and future 2.0). http://sourceforge.net/projects/mysql-python/ http://pypi.python.org/pypi/MySQL-python/ http://mysql-python.blogspot.com/ -- Patriotism means to stand by the country.

hcpy: a console-based simple RPN calculator
by someonesdad1＠gmail.com 04 Feb '09

04 Feb '09

I'd like to announce an RPN calculator intended to be used in a console. It is based on two previous versions I wrote over the last 15 years in C and C++. Using python and mpmath (http:// code.google.com/p/mpmath) lets it be pure-python, yet much more powerful than I could write in the same amount of time in C/C++. I use this calculator for simple stuff at my computer every day, but now it has more horsepower than previous versions for when I need that power. It was influenced by the common functions of the HP-42s calculator, still my favorite hand-held calculator. It is intended to be simple-looking and austere. It is easily changeable and extensible and the configuration mechanisms let you make it work the way you want (well, within reason). You probably won't be interested in this calculator unless you're 1) a die-hard RPN user and 2) a command line weenie. It is open source and available at http://code.google.com/p/hcpy. I have added most of the functionality I envisioned, but the existing code is a bit of a hacked-together mess that really needs to be refactored. Still, I would really like some feedback on the tool, so please feel free to submit issues or send me email with any comments. someonesdad1(a)gmail.com

ANN: Gmatch, a tiny matcher of google-like queries
by denis-bz-gg＠t-online.de 02 Feb '09

02 Feb '09

Gmatch is a tiny matcher of google-like query patterns, called "goopat"s: gm = Gmatch( "color: blue - sky size: < 100" ) if gm.match( record ): ... matching_records = [rec for rec in records if gm.match( rec )] A "record" is a dict, or namedtuple, or Dotdict, or anything with record.get( key ) -> value. A "goopat" pattern is made up of the following elements, here with examples: color: a key or field name, followed by a ":" colon blu words made of letters and numbers match anywhere in a field, case-insensitive: blu matches Blue Blur sublunar blue sky match all the words, anywhere in a field, in any order: bluesky sky-blue "frisky ... blues" blue - sky blue but not sky -- put blanks around the "-" blue green - sky cloud blue and green but not sky and not cloud Double quotes are used for: "key.word", "http://a-b-c.net" names containing special characters "sky blue" sky, any amount of white space, then blue " sky blue " an exact word or phrase, not e.g. "frisky blues" r"regular expression" see http://docs.python.org/library/re.html . Gmatch compiles them with re.I case-insensitive and re.X, ignore white space except "\ " and "[ ]" ; Comparing: size: < <= > >= == != compare record.get( "size" ) to a number or string size: < 100 here size must be a number, or a string like "12.3" size: >= "Large" here it must be a string (beware: "Small" > "Large"). size: >= 100 < 200 matches sizes in the range 100 to 200. Notes, ramblings, corner cases ... (REs are pretty fast, ~ 20 Mbytes/sec on my mac ppc with python 2.5.1 .)

ANN: gmpy 1.04 released

Everyone, A new version of gmpy is available. gmpy is a wrapper for the GMP multiple-precision arithmetic library. This version of gmpy also supports the MPIR multiple-precision arithmetic library. gmpy 1.04 is available for download from http://code.google.com/p/gmpy/ There are several new features in this release: - Support for "rich comparisons". - Faster conversion to/from Python longs and other formats. - Fixed conversion of very large numbers to a string (only limited by memory). - Support for pickling. - Support for divexact. - Support for bit_length. - Special helper functions to improve the performance of mpmath, an arbitrary-precision floating point library written in Python, (http:// code.google.com/p/mpmath/). - Support for MPIR, an alternative multiple-precision library based on GMP, (http://mpir.org). - Added fround() to round an mpf value. WARNING! A (possibly) significant change was made to the handling of mpf values. GMP would frequently return more bits in a result than requested. This led to bugs such such as mpf(1.1)*mpf(1) != mpf(1.1) but mpf(1.1) / mpf(1) == mpf(1.1). The results of all floating point calculations are now rounded to the requested precision. mpf calculations may now produce slightly different results but the results are still within the bounds of the requested accuracy. As an alternative, the mpmath library provides consistently rounded floating point arithmetic and support a wide variety of transcendental functions. Comments on provided binaries The 32-bit Windows installers were compiled using MPIR 0.9 RC2 and will automatically recognize the CPU type and use code optimized for that CPU. gmpy 1.04 libraries are also provided for 64-bit Windows and Python 2.6. There is no installer; the appropriate gmpy.pyd must be copied to the site-packages directory. casevh
