PyDev 11.0.2 Released
by Fabio Zadrozny 29 Oct '23

29 Oct '23

PyDev 11.0.2 Release Highlights Continuing with the updates to Python 3.12, the new release integrates the latest version of typeshed (so, *from typing import override* is now properly recognized). Also, it's now possible to specify vmargs in the python interpreter (and not just in the launch configuration). For Python 3.11 onwards, *-Xfrozen_modules=off* is now set in the vm arguments by default. About PyDev PyDev is an open-source Python IDE on top of Eclipse for Python (also available for Python on Visual Studio Code). It comes with goodies such as code completion, syntax highlighting, syntax analysis, code analysis, refactor, debug, interactive console, etc. It is also available as a standalone through LiClipse with goodies such as multiple cursors, theming and support for many other languages, such as Django Templates, Jinja2, Html, JavaScript, etc. Links: PyDev: http://pydev.org PyDev Blog: http://pydev.blogspot.com PyDev on VSCode: http://pydev.org/vscode LiClipse: http://www.liclipse.com PyVmMonitor - Python Profiler: http://www.pyvmmonitor.com/ Cheers, Fabio Zadrozny

Python Virtual Shell 0.0b
by christos.jon...＠gmail.com 29 Oct '23

29 Oct '23

An attempt at Python virtual shell that mixes your native shell with Python with the goal of letting you use your regular shell but also use Python as effectively a shell scripting language, as an alternative to your shell's built-in scripting language. This was submitted before, but at a terrible time when the site was undergoing technical difficulties. The difficulties have since been resolved. Python Virtual Shell's homepage is at: https://cjshayward.com/pvsh/ I invite you to explore and improve it! Cordially, C.J.S. Hayward cjsh(a)cjshayward.com https://cjshayward.com <P><A HREF="http://https://cjshayward.com/pvsh/">Python Virtual Shell 0.0b</A> - A tool designed to let you use a regular LUM shell but also use Python as a shell scripting language (29-Sun-03)

SQLObject 3.10.3
by Oleg Broytman 25 Oct '23

25 Oct '23

Hello! I'm pleased to announce version 3.10.3, the 3rd bugfix release of branch 3.10 of SQLObject. What's new in SQLObject ======================= The contributors for this release are Igor Yudytskiy and shuffle (github.com/shuffleyxf). Thanks! Bug fixes --------- * Relaxed aliasing in ``SQLRelatedJoin`` introduced in 3.10.2 - aliasing is required only when the table joins with itself. When there're two tables to join aliasing prevents filtering -- wrong SQL is generated in ``relJoinCol.filter(thisClass.q.column)``. Drivers ------- * Fix(SQLiteConnection): Release connections from threads that are no longer active. This fixes memory leak in multithreaded programs in Windows. ``SQLite`` requires different connections per thread so ``SQLiteConnection`` creates and stores a connection per thread. When a thread finishes its connections should be closed. But if a program doesn't cooperate and doesn't close connections at the end of a thread SQLObject leaks memory as connection objects are stuck in ``SQLiteConnection``. On Linux the leak is negligible as Linux reuses thread IDs so new connections replace old ones and old connections are garbage collected. But Windows doesn't reuse thread IDs so old connections pile and never released. To fix the problem ``SQLiteConnection`` now enumerates threads and releases connections from non-existing threads. * Dropped ``supersqlite``. It seems abandoned. The last version 0.0.78 was released in 2018. Tests ----- * Run tests with Python 3.12. CI -- * GHActions: Ensure ``pip`` only if needed This is to work around a problem in conda with Python 3.7 - it brings in wrong version of ``setuptools`` incompatible with Python 3.7. For a more complete list, please see the news: http://sqlobject.org/News.html What is SQLObject ================= SQLObject is a free and open-source (LGPL) Python object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL/MariaDB (with a number of DB API drivers: ``MySQLdb``, ``mysqlclient``, ``mysql-connector``, ``PyMySQL``, ``mariadb``), PostgreSQL (``psycopg2``, ``PyGreSQL``, partially ``pg8000`` and ``py-postgresql``), SQLite (builtin ``sqlite``, ``pysqlite``); connections to other backends - Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB) - are less debugged). Python 2.7 or 3.4+ is required. Where is SQLObject ================== Site: http://sqlobject.org Download: https://pypi.org/project/SQLObject/3.10.3 News and changes: http://sqlobject.org/News.html StackOverflow: https://stackoverflow.com/questions/tagged/sqlobject Mailing lists: https://sourceforge.net/p/sqlobject/mailman/ Development: http://sqlobject.org/devel/ Developer Guide: http://sqlobject.org/DeveloperGuide.html Example ======= Install:: $ pip install sqlobject Create a simple class that wraps a table:: >>> from sqlobject import * >>> >>> sqlhub.processConnection = connectionForURI('sqlite:/:memory:') >>> >>> class Person(SQLObject): ... fname = StringCol() ... mi = StringCol(length=1, default=None) ... lname = StringCol() ... >>> Person.createTable() Use the object:: >>> p = Person(fname="John", lname="Doe") >>> p <Person 1 fname='John' mi=None lname='Doe'> >>> p.fname 'John' >>> p.mi = 'Q' >>> p2 = Person.get(1) >>> p2 <Person 1 fname='John' mi='Q' lname='Doe'> >>> p is p2 True Queries:: >>> p3 = Person.selectBy(lname="Doe")[0] >>> p3 <Person 1 fname='John' mi='Q' lname='Doe'> >>> pc = Person.select(Person.q.lname=="Doe").count() >>> pc 1 Oleg. -- Oleg Broytman https://phdru.name/ phd(a)phdru.name Programmers don't die, they just GOSUB without RETURN.

TatSu v5.9.0 - PEG parser generator
by Juancarlo Añez 22 Oct '23

22 Oct '23

竜 TatSu is a tool that takes grammars in a variation of EBNF as input, and outputs memoizing (Packrat) PEG parsers in Python. Why use a PEG parser? Because regular languages (those parsable with Python's `re` package) "cannot count". Any input with nested structures or with balancing of demarcations requires more than regular expressions to be parsed. 竜 TatSu can compile a grammar stored in a string into a `tatsu.grammars.Grammar` object that can be used to parse any given input, much like the `re` module does with regular expressions, or it can generate a Python module that implements the parser. On this release: - validate with Python 3.12 (#313 <https://github.com/neogeny/TatSu/pull/313>) - drop support for Python 3.10 (#313 <https://github.com/neogeny/TatSu/pull/313>) - move build configuration to pyproject.toml (#316 <https://github.com/neogeny/TatSu/pull/316> #317 <https://github.com/neogeny/TatSu/pull/317>) - evaluate constant to a Python literal when possible (#304 <https://github.com/neogeny/TatSu/issues/304> #320 <https://github.com/neogeny/TatSu/pull/320>) - fix comments_re and eol_comments_re so they effectively can be None ( #307 <https://github.com/neogeny/TatSu/pull/307> #312 <https://github.com/neogeny/TatSu/issues/312> #314 <https://github.com/neogeny/TatSu/pull/314>) - skip over whitespace and comments before memoizing (#305 <https://github.com/neogeny/TatSu/issues/305> #306 <https://github.com/neogeny/TatSu/pull/306> #309 <https://github.com/neogeny/TatSu/pull/309> #318 <https://github.com/neogeny/TatSu/pull/318>) - verify that () parses to None or is ignored (#308 <https://github.com/neogeny/TatSu/pull/308>) -- Juancarlo Añez mailto:apalala@gmail.com
