Magic variables: If you define one of these variables in your local scope, you can add information to tracebacks that happen in that context. This allows applications to add all sorts of extra information about the context of the error, including URLs, environmental variables, users, hostnames, etc. These are the variables we look for: ``__traceback_supplement__``: You can define this locally or globally (unlike all the other variables, which must be defined locally). ``__traceback_supplement__`` is a tuple of ``(factory, arg1, arg2...)``. When there is an exception, ``factory(arg1, arg2, ...)`` is called, and the resulting object is inspected for supplemental information. ``__traceback_info__``: This information is added to the traceback, usually fairly literally. ``__traceback_hide__``: If set and true, this indicates that the frame should be hidden from abbreviated tracebacks. This way you can hide some of the complexity of the larger framework and let the user focus on their own errors. By setting it to ``'before'``, all frames before this one will be thrown away. By setting it to ``'after'`` then all frames after this will be thrown away until ``'reset'`` is found. In each case the frame where it is set is included, unless you append ``'_and_this'`` to the value (e.g., ``'before_and_this'``). Note that formatters will ignore this entirely if the frame that contains the error wouldn't normally be shown according to these rules. ``__traceback_reporter__``: This should be a reporter object (see the reporter module), or a list/tuple of reporter objects. All reporters found this way will be given the exception, innermost first. ``__traceback_decorator__``: This object (defined in a local or global scope) will get the result of this function (the CollectedException defined below). It may modify this object in place, or return an entirely new object. This gives the object the ability to manipulate the traceback arbitrarily. The actually interpretation of these values is largely up to the reporters and formatters. ``collect_exception(*sys.exc_info())`` will return an object with several attributes: ``frames``: A list of frames ``exception_formatted``: The formatted exception, generally a full traceback ``exception_type``: The type of the exception, like ``ValueError`` ``exception_value``: The string value of the exception, like ``'x not in list'`` ``identification_code``: A hash of the exception data meant to identify the general exception, so that it shares this code with other exceptions that derive from the same problem. The code is a hash of all the module names and function names in the traceback, plus exception_type. This should be shown to users so they can refer to the exception later. (@@: should it include a portion that allows identification of the specific instance of the exception as well?) The list of frames goes innermost first. Each frame has these attributes; some values may be None if they could not be determined. ``modname``: the name of the module ``filename``: the filename of the module ``lineno``: the line of the error ``revision``: the contents of __version__ or __revision__ ``name``: the function name ``supplement``: an object created from ``__traceback_supplement__`` ``supplement_exception``: a simple traceback of any exception ``__traceback_supplement__`` created ``traceback_info``: the str() of any ``__traceback_info__`` variable found in the local scope (@@: should it str()-ify it or not?) ``traceback_hide``: the value of any ``__traceback_hide__`` variable ``traceback_log``: the value of any ``__traceback_log__`` variable ``__traceback_supplement__`` is thrown away, but a fixed set of attributes are captured; each of these attributes is optional. ``object``: the name of the object being visited ``source_url``: the original URL requested ``line``: the line of source being executed (for interpreters, like ZPT) ``column``: the column of source being executed ``expression``: the expression being evaluated (also for interpreters) ``warnings``: a list of (string) warnings to be displayed ``getInfo``: a function/method that takes no arguments, and returns a string describing any extra information ``extraData``: a function/method that takes no arguments, and returns a dictionary. The contents of this dictionary will not be displayed in the context of the traceback, but globally for the exception. Results will be grouped by the keys in the dictionaries (which also serve as titles). The keys can also be tuples of (importance, title); in this case the importance should be ``important`` (shows up at top), ``normal`` (shows up somewhere; unspecified), ``supplemental`` (shows up at bottom), or ``extra`` (shows up hidden or not at all). These are used to create an object with attributes of the same names (``getInfo`` becomes a string attribute, not a method). ``__traceback_supplement__`` implementations should be careful to produce values that are relatively static and unlikely to cause further errors in the reporting system -- any complex introspection should go in ``getInfo()`` and should ultimately return a string. Note that all attributes are optional, and under certain circumstances may be None or may not exist at all -- the collector can only do a best effort, but must avoid creating any exceptions itself. Formatters may want to use ``__traceback_hide__`` as a hint to hide frames that are part of the 'framework' or underlying system. There are a variety of rules about special values for this variables that formatters should be aware of. TODO: More attributes in __traceback_supplement__? Maybe an attribute that gives a list of local variables that should also be collected? Also, attributes that would be explicitly meant for the entire request, not just a single frame. Right now some of the fixed set of attributes (e.g., source_url) are meant for this use, but there's no explicit way for the supplement to indicate new values, e.g., logged-in user, HTTP referrer, environment, etc. Also, the attributes that do exist are Zope/Web oriented. More information on frames? cgitb, for instance, produces extensive information on local variables. There exists the possibility that getting this information may cause side effects, which can make debugging more difficult; but it also provides fodder for post-mortem debugging. However, the collector is not meant to be configurable, but to capture everything it can and let the formatters be configurable. Maybe this would have to be a configuration value, or maybe it could be indicated by another magical variable (which would probably mean 'show all local variables below this frame') """ show_revisions = 0 def __init__(self, limit=None): self.limit = limit def getLimit(self): limit = self.limit if limit is None: limit = getattr(sys, 'tracebacklimit', None) return limit def getRevision(self, globals): if not self.show_revisions: return None revision = globals.get('__revision__', None) if revision is None: #

 * @projectDescription Easy element scrolling using jQuery.
 * Tested with jQuery 1.2.1. On FF 2.0.0.11, IE 6, Opera 9.22 and Safari 3 beta. on Windows.
 *
 * @author Ariel Flesler
 * @version 1.3.3
 *
 * @id jQuery.scrollTo
 * @id jQuery.fn.scrollTo
 * @param {String, Number, DOMElement, jQuery, Object} target Where to scroll the matched elements.
 *	  The different options for target are:
 *		- A number position (will be applied to all axes).
 *		- A string position ('44', '100px', '+=90', etc ) will be applied to all axes
 *		- A jQuery/DOM element ( logically, child of the element to scroll )
 *		- A string selector, that will be relative to the element to scroll ( 'li:eq(2)', etc )
 *		- A hash { top:x, left:y }, x and y can be any kind of number/string like above.
 * @param {Number} duration The OVERALL length of the animation, this argument can be the settings object instead.
 * @param {Object} settings Hash of settings, optional.
 *	 @option {String} axis Which axis must be scrolled, use 'x', 'y', 'xy' or 'yx'.
 *	 @option {Number} duration The OVERALL length of the animation.
 *	 @option {String} easing The easing method for the animation.
 *	 @option {Boolean} margin If true, the margin of the target element will be deducted from the final position.
 *	 @option {Object, Number} offset Add/deduct from the end position. One number for both axes or { top:x, left:y }.
 *	 @option {Object, Number} over Add/deduct the height/width multiplied by 'over', can be { top:x, left:y } when using both axes.
 *	 @option {Boolean} queue If true, and both axis are given, the 2nd axis will only be animated after the first one ends.
 *	 @option {Function} onAfter Function to be called after the scrolling ends. 
 *	 @option {Function} onAfterFirst If queuing is activated, this function will be called after the first scrolling ends.
 * @return {jQuery} Returns the same jQuery object, for chaining.
 *
 * @example $('div').scrollTo( 340 );
 *
 * @example $('div').scrollTo( '+=340px', { axis:'y' } );
 *
 * @example $('div').scrollTo( 'p.paragraph:eq(2)', 500, { easing:'swing', queue:true, axis:'xy' } );
 *
 * @example var second_child = document.getElementById('container').firstChild.nextSibling;
 *			$('#container').scrollTo( second_child, { duration:500, axis:'x', onAfter:function(){
 *				alert('scrolled!!');																   
 *			}});
 *
 * @example $('div').scrollTo( { top: 300, left:'+=200' }, { offset:-20 } );
 *
 * Notes:
 *  - jQuery.scrollTo will make the whole window scroll, it accepts the same arguments as jQuery.fn.scrollTo.
 *	- If you are interested in animated anchor navigation, check http://jquery.com/plugins/project/LocalScroll.
 *	- The options margin, offset and over are ignored, if the target is not a jQuery object or a DOM element.
 *	- The option 'queue' won't be taken into account, if only 1 axis is given.
