hello folks after several people (several > 10) contacted me and said "IMHO 'construct' is a good candidate for stdlib", i thought i should give it a try. of course i'm not saying it should be included right now, but in 6 months time, or such a timeframe (aiming at python 2.6? some 2.5.x release?) a little intro: "Construct" ( http://pyconstruct.sourceforge.net/) is a library for declaratively defining data structures at the bit-level. these constructs can be used to parse raw data into objects, or build objects into raw data. you can see a couple of examples at http://pyconstruct.wikispaces.com/examples being "data structures" they are not limited to simple structures -- they can be linked lists, for example, or an enitre efl32 file, with sections and pointers (included in the distribution). currently i'm writing a parser of ext2 file systems, to allow inspecting file systems without mounting. why include Construct? * the struct module is very nice, but very limited and non-pythonic as well * pure python (no platform/security issues) * lots of people need to parse and build binary data structures, it's not an esoteric library * license: public domain * quite a large user base for such a short time (proves the need of the community) * easy to use and extend (follows the componentization pattern) * declarative: you don't need to write executable code for most cases why not: * the code is (very) young. stable and all, but less than a month on the loose. * new features may still be added / existing ones may be changed in a non-backwards-compatible manner so why am i saying this now, instead of waiting a few months for it to maturet? well, i wanted to get feedback. those of you who have seen/used the library, please tell me what you think: * is it suitable for a standard library? * what more features would you want? * any changes you think are necessary? i'm starting this now, in order to have a mature version in the (near) future. thanks, -tomer -------------- next part -------------- An HTML attachment was scrubbed...
