ANN: PyEnchant 1.2.0
by Ryan Kelly 18 Sep '07

18 Sep '07

Hi All, I'm pleased to announce the release of PyEnchant version 1.2.0. This version includes some important updates in the underlying enchant library, and implements basic "filters" to allow skipping of email addresses, WikiWords, URLs, etc during a spellchecking session. Cheers, Ryan About: ------ Enchant (http://www.abisource.com/enchant/) is the spellchecking package behind the AbiWord word processor, is being considered for inclusion in the KDE office suite, and is proposed as a FreeDesktop.org standard. It's completely cross-platform because it wraps the native spellchecking engine to provide a uniform interface. PyEnchant brings this simple, powerful and flexible spellchecking engine to Python: http://pyenchant.sourceforge.net/ It also provides extended functionality including classes for tokenizing text and iterating over the spelling errors in it, as well as a ready-to-use text interface and wxPython dialog. Current Version: 1.2.0 Licence: LGPL with exemptions, as per Enchant itself ChangeLog for 1.2.0: -------------------- * Implemented "filters" that allow tokenization to skip common word forms such as URLs, WikiWords, email addresses etc. * Now ships with enchant-1.3.0, meaning: * PWLs can return a useful list of suggestions rather than the empty list * Hunspell replaces MySpell as the default Windows backend * Tokenization doesnt split words at non-alpha characters by default * GtkSpellCheckerDialog contributed by Fredrik Corneliusson * Removed deprecated functionality: * Dict.add_to_personal * All registry handling functionality from enchant.utils * enchant.utils.SpellChecker (use enchant.checker.SpellChecker) * Removed PyPWL, as native enchant PWLs can now suggest corrections -- Ryan Kelly http://www.rfk.id.au | This message is digitally signed.

Python 3000 released as 3.0a1
by Guido van Rossum 31 Aug '07

31 Aug '07

[Bcc: python-list(a)python.org] The first Python 3000 release is out -- Python 3.0a1. Be the first one on your block to download it! http://python.org/download/releases/3.0/ Excerpts: Python 3000 (a.k.a. "Py3k", and released as Python 3.0) is a new version of the language that is incompatible with the 2.x line of releases. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features have finally been removed. This is an ongoing project; the cleanup isn't expected to be complete until 2008. In particular there are plans to reorganize the standard library namespace. The release plan is to have a series of alpha releases in 2007, beta releases in 2008, and a final release in August 2008. The alpha releases are primarily aimed at developers who want a sneak peek at the new langauge, especially those folks who plan to port their code to Python 3000. The hope is that by the time of the final release, many 3rd party packages will already be available in a 3.0-compatible form. More links: * Online docs: http://docs.python.org/dev/3.0/ * What's new: http://docs.python.org/dev/3.0/whatsnew/3.0.html * Source tar ball: http://python.org/ftp/python/3.0/Python-3.0a1.tgz * Windows MSI installer: http://python.org/ftp/python/3.0/python-3.0a1.msi * PEP 3000: http://python.org/dev/peps/pep-3000/ * Issue tracker: http://bugs.python.org/ * Py3k dev list: http://mail.python.org/mailman/listinfo/python-3000/ * Conversion tool for Python 2.x code: http://svn.python.org/view/sandbox/trunk/2to3/ -- --Guido van Rossum (home page: http://www.python.org/~guido/)

[ANN] Bazaar 0.90 and user survey
by James Westby 28 Aug '07

28 Aug '07

I am happy to announce the release of Bazaar 0.90. This release provides over 50 changes, including: * 10 bugfixes * 25 user visible improvements * 20+ enhancements to internals. Some of the highlights include pyrex implementations of some performance critical functions, algorithm changes giving performance improvements to merging and merge directive generation, a send command which will make contributing changes back easier and connection sharing to reduce the number of connections that must be made to a remote location in some situations. As noted above this release includes optional pyrex implementations of some performance critical functions. In order to use these you need to compile them before installing. If you are running from source then it is recommended to use 'make' to build and install Bazaar. 'make' will take care of compiling the extensions for you. If you use 'python setup.py install' then the extensions will also be compiled for you as well. Note that you will need the python headers installed in order to compile the extensions against them. On some Linux distributions that may involve installing an extra package (commonly called python-dev or python-devel). If you would like to help us improve Bazaar by telling us about yourself and what we could do better, please register and complete the online survey here: http://www.surveymonkey.com/s.aspx?sm=L94RvLswhKdktrxiHWiX3g_3d_3d. Tarballs: http://bazaar-vcs.org/releases/src/bzr-0.90.tar.gz and GPG signature: http://bazaar-vcs.org/releases/src/bzr-0.90.tar.gz.sig (signed with B577FE13) I've attached a summary of the changes in 0.90 since 0.18, based on NEWS. Since the release candidate there has been one important regression fixed involving URLs using the bzr:// protocol. Many thanks to all the contributors to this release! Thanks, James Westby - 0.90 Release Manager bzr 0.90 2007-08-28 BUGFIXES: * Fix ''bzr info bzr://host/'' and other operations on ''bzr://' URLs with an implicit port. We were incorrectly raising PathNotChild due to inconsistent treatment of the ''_port'' attribute on the Transport object. (John Arbash Meinel, Andrew Bennetts, #133965) * ``bzr init`` should connect to the remote location one time only. We have been connecting several times because we forget to pass around the Transport object. This modifies ``BzrDir.create_branch_convenience``, so that we can give it the Transport we already have. (John Arbash Meinel, Vincent Ladeuil, #111702) * Get rid of sftp connection cache (get rid of the FTP one too). (Vincent Ladeuil, #43731) * bzr branch {local|remote} remote don't try to create a working tree anymore. (Vincent Ladeuil, #112173) * All identified multiple connections for a single bzr command have been fixed. See bzrlib/tests/commands directory. (Vincent Ladeuil) * ``bzr rm`` now does not insist on ``--force`` to delete files that have been renamed but not otherwise modified. (Marius Kruger, #111664) * ``bzr selftest --bench`` no longer emits deprecation warnings (Lukáš Lalinský) * ``bzr status`` now honours FILE parameters for conflict lists (Aaron Bentley, #127606) * ``bzr checkout`` now honours -r when reconstituting a working tree. It also honours -r 0. (Aaron Bentley, #127708) * ``bzr add *`` no more fails on Windows if working tree contains non-ascii file names. (Kuno Meyer, #127361) * allow ``easy_install bzr`` runs without fatal errors. (Alexander Belchenko, #125521) * Graph._filter_candidate_lca does not raise KeyError if a candidate is eliminated just before it would normally be examined. (Aaron Bentley) * SMTP connection failures produce a nice message, not a traceback. (Aaron Bentley) IMPROVEMENTS: * Documentation is now organized into multiple directories with a level added for different languages or locales. Added the Mini Tutorial and Quick Start Summary (en) documents from the Wiki, improving the content and readability of the former. Formatted NEWS as Release Notes complete with a Table of Conents, one heading per release. Moved the Developer Guide into the main document catalog and provided a link from the developer document catalog back to the main one. (Ian Clatworthy, Sabin Iacob, Alexander Belchenko) * Don't show "dots" progress indicators when run non-interactively, such as from cron. (Martin Pool) * ``info`` now formats locations more nicely and lists "submit" and "public" branches (Aaron Bentley) * New ``pack`` command that will trigger database compression within the repository (Robert Collins) * Implement ``_KnitIndex._load_data`` in a pyrex extension. The pyrex version is approximately 2-3x faster at parsing a ``.kndx`` file. Which yields a measurable improvement for commands which have to read from the repository, such as a 1s => 0.75s improvement in ``bzr diff`` when there are changes to be shown. (John Arbash Meinel) * Merge is now faster. Depending on the scenario, it can be more than 2x faster. (Aaron Bentley) * Give a clearer warning, and allow ``python setup.py install`` to succeed even if pyrex is not available. (John Arbash Meinel) * ``DirState._read_dirblocks`` now has an optional Pyrex implementation. This improves the speed of any command that has to read the entire DirState. (``diff``, ``status``, etc, improve by about 10%). ``bisect_dirblocks`` has also been improved, which helps all ``_get_entry`` type calls (whenever we are searching for a particular entry in the in-memory DirState). (John Arbash Meinel) * ``bzr pull`` and ``bzr push`` no longer do a complete walk of the branch revision history for ui display unless -v is supplied. (Robert Collins) * ``bzr log -rA..B`` output shifted to the left margin if the log only contains merge revisions. (Kent Gibson) * The ``plugins`` command is now public with improved help. (Ian Clatworthy) * New bundle and merge directive formats are faster to generate, and more robust against email mangling. New `send` command replaces `bundle-revisions` and `merge-directive`. (Aaron Bentley) * Annotate merge now works when there are local changes. (Aaron Bentley) * Commit now only shows the progress in terms of directories instead of entries. (Ian Clatworthy) * Fix ``KnitRepository.get_revision_graph`` to not request the graph 2 times. This makes ``get_revision_graph`` 2x faster. (John Arbash Meinel) * Fix ``VersionedFile.get_graph()`` to avoid using ``set.difference_update(other)``, which has bad scaling when ``other`` is large. This improves ``VF.get_graph([version_id])`` for a 12.5k graph from 2.9s down to 200ms. (John Arbash Meinel) * The ``--lsprof-file`` option now generates output for KCacheGrind if the file starts with ``callgrind.out``. This matches the default file filtering done by KCacheGrind's Open Dialog. (Ian Clatworthy) * Fix ``bzr update`` to avoid an unnecessary ``branch.get_master_branch`` call, which avoids 1 extra connection to the remote server. (Partial fix for #128076, John Arbash Meinel) * Log errors from the smart server in the trace file, to make debugging test failures (and live failures!) easier. (Andrew Bennetts) * The HTML version of the man page has been superceded by a more comprehensive manual called the Bazaar User Reference. This manual is completed generated from the online help topics. As part of this change, limited reStructuredText is now explicitly supported in help topics and command help with 'unnatural' markup being removed prior to display by the online help or inclusion in the man page. (Ian Clatworthy) * HTML documentation now use files extension *.html (Alexander Belchenko) * The cache of ignore definitions is now cleared in WorkingTree.unlock() so that changes to .bzrignore aren't missed. (#129694, Daniel Watkins) * ``bzr selftest --strict'' fails if there are any missing features or expected test failures. (Daniel Watkins, #111914) * Link to registration survey added to README. (Ian Clatworthy) * Windows standalone installer show link to registration survey when installation finished. (Alexander Belchenko) LIBRARY API BREAKS: * Deprecated dictionary ``bzrlib.option.SHORT_OPTIONS`` removed. Options are now required to provide a help string and it must comply with the style guide by being one or more sentences with an initial capital and final period. (Martin Pool) * KnitIndex.get_parents now returns tuples. (Robert Collins) * Ancient unused ``Repository.text_store`` attribute has been removed. (Robert Collins) * The ``bzrlib.pack`` interface has changed to use tuples of bytestrings rather than just bytestrings, making it easier to represent multiple element names. As this interface was not used by any internal facilities since it was introduced in 0.18 no API compatibility is being preserved. The serialised form of these packs is identical with 0.18 when a single element tuple is in use. (Robert Collins) INTERNALS: * merge now uses ``iter_changes`` to calculate changes, which makes room for future performance increases. It is also more consistent with other operations that perform comparisons, and reduces reliance on Tree.inventory. (Aaron Bentley) * Refactoring of transport classes connected to a remote server. ConnectedTransport is a new class that serves as a basis for all transports needing to connect to a remote server. transport.split_url have been deprecated, use the static method on the object instead. URL tests have been refactored too. (Vincent Ladeuil) * Better connection sharing for ConnectedTransport objects. transport.get_transport() now accepts a 'possible_transports' parameter. If a newly requested transport can share a connection with one of the list, it will. (Vincent Ladeuil) * Most functions now accept ``bzrlib.revision.NULL_REVISION`` to indicate the null revision, and consider using ``None`` for this purpose deprecated. (Aaron Bentley) * New ``index`` module with abstract index functionality. This will be used during the planned changes in the repository layer. Currently the index layer provides a graph aware immutable index, a builder for the same index type to allow creating them, and finally a composer for such indices to allow the use of many indices in a single query. The index performance is not optimised, however the API is stable to allow development on top of the index. (Robert Collins) * ``bzrlib.dirstate.cmp_by_dirs`` can be used to compare two paths by their directory sections. This is equivalent to comparing ``path.split('/')``, only without having to split the paths. This has a Pyrex implementation available. (John Arbash Meinel) * New transport decorator 'unlistable+' which disables the list_dir functionality for testing. * Deprecated ``change_entry`` in transform.py. (Ian Clatworthy) * RevisionTree.get_weave is now deprecated. Tree.plan_merge is now used for performing annotate-merge. (Aaron Bentley) * New EmailMessage class to create email messages. (Adeodato Simó) * Unused functions on the private interface KnitIndex have been removed. (Robert Collins) * New ``knit.KnitGraphIndex`` which provides a ``KnitIndex`` layered on top of a ``index.GraphIndex``. (Robert Collins) * New ``knit.KnitVersionedFile.iter_parents`` method that allows querying the parents of many knit nodes at once, reducing round trips to the underlying index. (Robert Collins) * Graph now has an is_ancestor method, various bits use it. (Aaron Bentley) * The ``-Dhpss`` flag now includes timing information. As well as logging when a new connection is opened. (John Arbash Meinel) * ``bzrlib.pack.ContainerWriter`` now returns an offset, length tuple to callers when inserting data, allowing generation of readv style access during pack creation, without needing a separate pass across the output pack to gather such details. (Robert Collins) * ``bzrlib.pack.make_readv_reader`` allows readv based access to pack files that are stored on a transport. (Robert Collins) * New ``Repository.has_same_location`` method that reports if two repository objects refer to the same repository (although with some risk of false negatives). (Andrew Bennetts) * InterTree.compare now passes require_versioned on correctly. (Marius Kruger) * New methods on Repository - ``start_write_group``, ``commit_write_group``, ``abort_write_group`` and ``is_in_write_group`` - which provide a clean hook point for transactional Repositories - ones where all the data for a fetch or commit needs to be made atomically available in one step. This allows the write lock to remain while making a series of data insertions. (e.g. data conversion). (Robert Collins) * In ``bzrlib.knit`` the internal interface has been altered to use 3-tuples (index, pos, length) rather than two-tuples (pos, length) to describe where data in a knit is, allowing knits to be split into many files. (Robert Collins) * ``bzrlib.knit._KnitData`` split into cache management and physical access with two access classes - ``_PackAccess`` and ``_KnitAccess`` defined. The former provides access into a .pack file, and the latter provides the current production repository form of .knit files. (Robert Collins) TESTING: * Remove selftest ``--clean-output``, ``--numbered-dirs`` and ``--keep-output`` options, which are obsolete now that tests are done within directories in $TMPDIR. (Martin Pool) * The SSH_AUTH_SOCK environment variable is now reset to avoid interaction with any running ssh agents.

ANN: SCF released
by hg 26 Aug '07

26 Aug '07

Dear all, I am releasing much of my work including SCF (Cross platform Smart Card library & Tools written in Python) to the GPL license. If interested, go to http://www.SnakeCard.com/Source.html I am moving the doc to doxygen and cleaning up the code, so what you'll see there will change in the course of the next few weeks - basically can only get meaningful info on the classes hierarchy at this stage. I am looking for a free subversion server resource to put the code ... if you know of any. Some of the work there will be windows-only related (GINA, activeX components ... and not coded in Python) and the applets JavaCard and BasicCard ... I'm releasing these during the next few days. Regards,

ANN: PyPE 2.8.6
by Josiah Carlson 26 Aug '07

26 Aug '07

=== What is PyPE? === PyPE (Python Programmers' Editor) was written in order to offer a lightweight but powerful editor for those who think emacs is too much and idle is too little. Syntax highlighting is included out of the box, as is multiple open documents via tabs. Beyond the basic functionality, PyPE offers an expandable source tree, filesystem browser, draggable document list, todo list, filterable function list, find and replace bars (no dialog to find or replace simple strings), recordable and programmable macros, spell checker, reconfigurable menu hotkeys, triggers, find in files, external process shells, and much more. === More Information === If you would like more information about PyPE, including screenshots, where to download the source or windows binaries, bug tracker, contact information, or a somewhat complete listing of PyPE's features, visit PyPE's home on the web: http://pype.sf.net/index.shtml If you have any questions about PyPE, please contact me, Josiah Carlson, aka the author of PyPE, at jcarlson at uci.edu (remember to include "PyPE" in the subject). PyPE 2.8.6 includes the following changes and bugfixes since release 2.8.5: (fixed) a bug with "Wrap Try/Except" as per emailed bug report from Ian York. (added) ability to choose what port PyPE will listen on via --port= . (fixed) workspaces in wxPython 2.8+, patch thanks to Craig Mahaney. (added) explicit exclude dirs for find in files, patch thanks to Craig Mahaney. (added) paste and down mechanism to paste and move the cursor down, patch thanks to Craig Mahaney. (added) delete right mechanism to delete everything from the cursor to the end of the line, patch thanks to Craig Mahaney. (added) delete line mechanism to delete the current line, patch thanks to Craig Mahaney. (added) paste rectangle command for rectangular pasting, patch thanks to Craig Mahaney. (fixed) support for alternate background colors thanks to bug report from Craig Mahaney. (added) macro support to Craig Mahaney's added functionality. (added) implementation for regular expression replacements, possibly to be integrated as part of a 'replace in all open documents' in the future. (added) automatic spellcheck for text and tex documents of up to 200,000 byes in size. Will only spellcheck if the user has enabled "check syntax" in the "Realtime Options". (fixed) issue when trying to save language settings when cursor position is not to be saved. (added) support for \chapter section delimiter in *tex files. (fixed) issue that prevented the highest level source listing from being sorted in the Name and Line sorted source trees. (changed) rather than reading and executing a file for configuration loading, we now use a variant of the 'unrepr()' mechanism with support for True/False. (changed) find/replace bar now uses variant of 'unrepr()' rather than the compiler module directly. (changed) moved parsers.py to plugins and stopped using import * to get its contents.
