Changelog

0.9.8 (Sep 25, 2009)

• Added support for serverside-callbacks to widgets.
• Added resource-aggregation support that allows deliver a single resource file to reduce request-load.
• Added render_filter to apply filtering to rendered resource-links. This can adapt output to various doc-styles, or replace links with CDN-locations.
• Introduced “variants” for resources that allow to select normal, minified, packed or debug variants of JS and CSS files.
• Added require_once-protection of JS-files that puts guards against multiple inclusion around them so that loaded sub-pages via AJAX don’t reload a library.
• Fixed #45: Python 2.4 support.
• Fixed #30: recursive js_function calls get quoted badly.

0.9.7 (Jun 19, 2008)

• Fixed mayhem created by undiscussed and poorly tested changes introduced in the previous release. Closes TW’s #42 and tw,forms’ #32, #39. Thanks go to anthonyt for submitting a patch (#29) which solved the issue although it hasn’t been applied due to a refactor in an attempt to solve the root cause.

0.9.6 (Jun 4, 2008)

• Fix to render widgets with non-binary attributes properly (checked=”checked” vs. checked=”True”).
• Fix to allow mutiple forms to display validation errors on a single page.
• Added Argspec cache which provides about a 5% boost in speed.
• Added Ability for toscawidgets to choose a template engine based on the default engine provided by the framework.
• Fix to initialization so that params using properties may be set properly.

0.9.5 (unreleased)

0.9.4 (Dec 8, 2008)

• Fix to tw.core.util.unflatten_args() by Philip Charlesworth from #28
• Bumped up Simplejson requirement to > 2.x and updated TWEncoder for compatibility with it.

0.9.3 (Aug 17, 2008)

• Added support for TurboGears?-1.5/CherryPy-3.1, thanks to Dag Brattli.

• tw.api.make_middleware() no longer stacks the RegistryManager by default since ususally TW is stacked above a RegistryManager in a larger app.

  Warning

  This might break your app if you’re not using a RegistryManager in your wsgi pipeline. If this is the case you’ll notice because TW will complain from a ‘paste.registry’ missing key from environ, if this is the case you can fix it by passing stack_registry = True as a keyword argument to tw.api.make_middleware() when configuring TW’s middleware.

• Fixed a big which caused resources to be injected twice when calling tw.api.inject_resources() twice.

• Greatly simplified tw.core.resource_injector.injector_middleware() thanks to WebOb.

• Optimized tw.api.Widget.update_params() logic.

  Warning

  There’s a slight change in behaviour but it will probably not affect anyone: callable parameters passed to Widget.display() are no longer called automatically since it makes no sense to do so and incurrs in a performance penalty.

• Added a headbottom location where tw.api.Resource instances can be injected.

0.9.2 (Jun 8, 2008)

• Template engine plugins are now loaded lazily.
• The v=modfied_time query string argument is no longer appended to resources since this method is not reliable with zipped eggs and causes some trouble. As a plus requests should now be faster since there are no disk hits for this reason.
• The CP filter in mods.tg now handles staic file serving instead of registering directories with CP’s static filter so resources from zipped eggs work properly.
• Implemented a setuptools commands to copy all static reosurces from a series of distributions into a direcory where a fast web-server can serve them. Optionally, if YUICompressor is installed, it can compress CSS and JS in the destination directory.
• Removed dependency from Paste, changed to lighter WebOb.
• TW’s middleware can now serve static resources from zipped eggs.
• feeder.py is no longer included.
• js_function arguments can now include other js_calls and js_callbacks at any level of nesting.
• repetitions and template caches are now LRUCaches to set an upper limit on memory usage.

0.9.1 (Jun, 1 2008)

• made inject_resources default in middleware since else dynamic js calls wont be included

0.9 (Jun, 1 2008)

• retrieve_css and retrieve_javascript have been deprecated and now return empty lists so resources are not included twice in TG1.
• tw.mods.tg now injects resources with resource injector
• JSLink and CSSLink now allow to override link to specify external resources. (Closes #7)
• Removed hard dependency from PasteScript.
• ToscaWidgets no longer has any external dependency with C extensions since dependencies on RuleDispatch and PyProtocols have been dropped
• display, render, adapt_value and retrieve_resources are no longer generic functions but are still exported so they can be easily extended with PEAK-Rules if neccesary
• Removed un-needed dependency from decorator module.

0.8.7 (unreleased)

• WidgetRepeaters don’t have a max_repetitions limitiation anymore since repetitions are now generated dynamically. Thanks to Paul Johnston.

0.8.6.1 (May, 29 2008)

• Fixed a bug introduced in display machinery rewrite which caused render to return Streams and ElementStreams on some circumstances.

0.8.6 (May, 29 2008)

• Removed use of RuleDispatch but left the requirement in order not to break backwards compatibility. Use of TW’s generic functions will issue DeprecationWarnings. Please fix your code ASAP (use peak.rules if absolutely need gfs) since deprecated code will be removed in 0.9.
• fixed memory leak caused by function closures passed to the template context when using genshi.
• injector_middleware now properly handles wrapped apps that use the write func returned by start_response
• Docs are finally hitting the repository!
• tw.core.resource_injector.inject_resources() has changed it’s signature making resources an optional parameter and switched places with html.

0.8.5 (Apr, 25 2008)

• PylonsHostFramework no longer adds the extra_vars_func by default which made available Pylons’s SOPs in every widget template namespace since some widgets are rendered outside the Pylons’ app context (ie: resources). The best practice to make thsi symbols available on a per-widget base is to pass them as parameters when rendering or make use of callables to provide params at request time.

0.8.[1,2,3,4] (Apr, 19 2008)

• Fixed various import bugs introduced in 0.8

0.8 (Apr. 19 2008)

• Changed the name of the “toscawidgets” namespace to “tw” and moved all the core stuff to tw.core. Now external widget eggs packages get grafted (via namespace packages) in the “tw” namespace. Example: “from toscawidgets.widgets import forms” now becomes “from tw import forms”

0.3 (Apr. 19 2008)

• Removed lxml dependency for resource injection. Now using simple regular expressions.

0.2 (Jan. 25 2008)

• Configured apydia to generate API docs.
• Links now add a v=%(mtime)d parameter to the URL to help against IEs aggresive cacheing

0.2rc2 (Nov. 19 2007)

• Reworded docs/index.txt

0.2rc1 (Nov. 19 2007)

• Added a Trove classifier to the PasteScript template.
• Various bugs and rough edges have been polished.
• Upated Pylons utilities to play well with version >= 0.9.6.
• Better support for Mako in Pylons projects.
• Changed the interface of the HostFramework (please read http://wiki.pylonshq.com/x/1YGq to see how it is initialized now).
• Added a switch to TGWidgetsMiddleware to use lxml to inject resources in the page.
• Removed use of DecoratorTools in favor of decorator since it handles signature preservation already (no need to reinvent its wheel)
• Refactored rendering behavior of Widget into Renderable base class.
• Changed signature of EngineManager.render and EngineManager.display. WARNING: Custom display rules should be adapted.
• EngineManager._initialize_engine is now deprecated.
• TG apps can now be mounted at different paths than / and TW’s static resources will be served properly. Thanks to Noah Gift for reporting the problem.
• Removed DeprecationWarnings thrown by latest RuleDispatch. Patch from Florent Aide.
• In mod.tg: widgets included at tg.include_widgets are now preloaded on first display so their directories get registered with CherryPy. Thanks to Dennis Muhlestein for the report and a test app.
• Widgets now support children with ids beginning with an underscore.
• Widgets now allow a callable to provide default values.
• js_function now allows now properly generates attribute accesses. Thanks to patch from Claudio S. Martinez.
• PriorityDisambiguated generic function calls are now logged to aid in tracing their execution paths if they’re not properly bundled in the same class/module.
• Widgets now support i18n. The translating function is provided by the HostFramework object at the translator attribute. To translate strings declared at import or initialization time (when translator might not be initialized yet), the lazystring function (adapted form TG) is provided.
• EngineManager.load_engine now accepts a distribution parameter to load an engine from a specific setuptools distribution. WARNING: Former load_engine_from_distribution is deprecated.
• link is now a property of Link which returns it’s computed url. Note that, ATM, it can only be queried precisely during a request.
• displays_on and engine_name can now be passed as arguments to display.
• pre_init and post_init are no longer generic functions. Pre-initialization is now done in __new__ and post-initialization in post_init, a special method called by a wrapper around __init__ after all cooperative inits have ran.
• Using DecoratorTools to create 2.3 compatible decorators that preserve decorated function’s signature and docstrings.
• WidgetRepeater now adjusts it’s repetititions automatically based on the length of value up to a maximun of max_repetitions.
• js_callback now accepts a called js_function as an argument and will create a js function that will make the call passed as argument when invoked.
• python-cjson no longer required. Substituted by simplejson in order to avoid dependence on another C extension module. If python-cjson is installed it will be used instead for performance.
• New IECSSLink and IECSSSource to conditionally include source/links to trick dumb IE.
• Links now allow a pkg_resources.Requirement instance as modname to point to the root of an egg distribution. Thanks to Robin Bryce.

0.1a1 (Jan. 19 2007)

• ToscaWidgets now requires python-cjson for encoding of js_function args.
• toscawidgets.js.js_function has changed semantics. It’s no longer a decorator and no longer lets you adapt values from python to JS manually. It uses cjson.encode to encode given parameters so more “JS-like” parameters must be passed explicitly.
• The tgsample sample app now shows rendering on both kid and genshi templates. The tgsample-genshi sample app has been removed.
• Widget templates now have a display_child function to reduce boiler-plate when displaying childs. It takes care of passing the value and args to child widgets allowing overrides in the template.
• The engine name of the page root widgets are displayed on can now be overriden for a request by setting the toscawidgets.framework.default_view attribute. Frameworks which only instantiate their HostFramework object once for the lifetime of the process should take special care (turbogears).
• Widget now has a “displays_on” read-only property that returns the engine name of the widget/page the widget should display on. This simplifies much display rules.
• toscawidgets.resources.Link no longer accepts modname and filename as positional arguments. Should pass them as kw. args.
• toscawidgets.js_interface has moved to toscawidgets.js.
• MochiKit no longer included in core distribution. Now distributed separately as twMochiKit.
• Fixed dependencies and requirements and setting http://toscawidgets.org/download/ as the main download location for neccesary pre-built binaries. easy_install should be able to do it’s magic properly now.
• Form widgets no longer included in core distribution. Now distributed separately as twForms (former ToscaWidgetsForms)
• First ToscaWidgets public release.
