` directive.
* Improve error reporting when accessing an attribute in a Python expression
raises an `AttributeError` (ticket #191).
* The `Markup` class now supports mappings for right hand of the `%` (modulo)
operator in the same way the Python string classes do, except that the
substituted values are escape. Also, the special constructor which took
positional arguments that would be substituted was removed. Thus the
`Markup` class now supports the same arguments as that of its `unicode`
base class (ticket #211).
* The `Template` class and its subclasses, as well as the interpolation API,
now take an `filepath` parameter instead of `basedir` (ticket #207).
* The `XHTMLSerializer` now has a `drop_xml_decl` option that defaults to
`True`. Setting it to `False` will cause any XML decl in the serialized
stream to be included in the output as it would for XML serialization.
* Add support for a protocol that would allow interoperability of different
Python packages that generate and/or consume markup, based on the special
`__html__()` method (ticket #202).
Version 0.4.4
http://svn.edgewall.org/repos/genshi/tags/0.4.4/
(Aug 14, 2007, from branches/stable/0.4.x)
* Fixed augmented assignment to local variables in Python code blocks.
* Fixed handling of nested function and class definitions in Python code
blocks.
* Includes were not raising `TemplateNotFound` exceptions even when no
fallback has been specified. That has been corrected.
* The template loader now raises a `TemplateNotFound` error when a previously
cached template is removed or renamed, where it previously was passing up
an `OSError`.
* The Genshi I18n filter can be configured to only extract messages found in
`gettext` function calls, ignoring any text nodes and attribute values
(ticket #138).
Version 0.4.3
http://svn.edgewall.org/repos/genshi/tags/0.4.3/
(Jul 17 2007, from branches/stable/0.4.x)
* The I18n filter no longer extracts or translates literal strings in
attribute values that also contain expressions.
* Added `loader_callback` option to plugin interface, which allows specifying
a callback function that the template loader should invoke whenever a new
template is loaded (ticket #130). Note that the value for this option can
not be specified as a string, only as an actual function object, which means
it is not available for use through configuration files.
* The I18n filter now extracts messages from gettext functions even inside
ignored tags (ticket #132).
* The HTML sanitizer now strips any CSS comments in style attributes, which
could previously be used to hide malicious property values.
* The HTML sanitizer now also removes any HTML comments encountered, as those
may be used to hide malicious payloads targetting a certain "innovative"
browser that goes and interprets the content of specially prepared comments.
* Attribute access in template expressions no longer silently ignores
exceptions other than `AttributeError` raised in the attribute accessor.
Version 0.4.2
http://svn.edgewall.org/repos/genshi/tags/0.4.2/
(Jun 20 2007, from branches/stable/0.4.x)
* The `doctype` parameter of the markup serializers now also accepts the "name"
of the doctype as string, in addition to the `(name, pubid, sysid)` tuple.
* The I18n filter was not replacing the original attributes with the
translation, but instead adding a second attribute with the same name.
* `TextTemplate` can now handle unicode source (ticket #125).
* A `` processing instruction containing trailing whitespace no
longer causes a syntax error (ticket #127).
* The I18n filter now skips the content of elements that have an `xml:lang`
attribute with a fixed string value. Basically, `xml:lang` can now be used
as a flag to mark specific sections as not needing localization.
* Added plugin for message extraction via Babel (http://babel.edgewall.org/).
Version 0.4.1
http://svn.edgewall.org/repos/genshi/tags/0.4.1/
(May 21 2007, from branches/stable/0.4.x)
* Fix incorrect reference to translation function in the I18N filter.
* The `ET()` function now correctly handles attributes with a namespace.
* XML declarations are now processed internally, as well as written to the
output when XML serialization is used (ticket #111).
* Added the functions `encode()` and `get_serializer()` to the `genshi.output`
module, which provide a lower-level API to the functionality previously only
available through `Stream.render()` and `Stream.serialize()`.
* The `DocType` class now has a `get(name)` function that returns a `DOCTYPE`
tuple for a given string.
* Added frameset variants to the `DocType` constants for HTML 4.01 and XHTML
1.0.
* Improved I18n extraction for pluralizable messages: for any translation
function with multiple string arguments (such as ``ngettext``), a single
item with a tuple of strings is yielded, instead an item for each string
argument.
* The `HTMLFormFiller` stream filter no longer alters form elements for which
the data element contains no corresponding item.
* Code in `` processing instructions no longer gets the special
treatment as Python code in template expressions, i.e. item and attribute
access are no longer interchangeable (which was broken in a number of ways
anyway, see ticket #113). This change does not affect expressions.
* Numerous fixes for the execution of Python code in `` processing
instructions (tickets #113 and #114).
* The `py:def` (and `#def`) directive now supports "star args" (i.e. `*args`
and `**kwargs`) in the function declaration (ticket #116).
Version 0.4
http://svn.edgewall.org/repos/genshi/tags/0.4.0/
(Apr 16 2007, from branches/stable/0.4.x)
* New example applications for CherryPy and web.py.
* The template loader now uses a LRU cache to limit the number of cached
templates to a configurable maximum. Also, a race condition in the template
loader was fixed by adding locking.
* A new filter (genshi.filters.HTMLFormFiller) was added, which can populate
HTML forms based on a dictionary of values.
* The set of permitted tag and attribute names for the HTMLSanitizer can now
be configured per instance.
* The template engine plugin now supports a range of options for
configuration, for example to set the default serialization method, the
default output encoding, or the default DOCTYPE.
* The ElementTree adaptation function `ET()` has moved into the `genshi.input`
module.
* Allow `when` directives to omit the test expression as long as the
associated choose directive does have one. In that case, the when branch is
followed if the expression of the choose directive evaluates to a truth
value.
* Unsuccessful attribute or item lookups now return `Undefined` objects for
nicer error messages.
* Split up the `genshi.template` module into multiple modules inside the new
`genshi.template` package.
* Results of expression evaluation are no longer implicitly called if they
are callable.
* Instances of the `genshi.core.Attrs` class are now immutable (they are
subclasses of `tuple` instead of `list`).
* `MarkupTemplate`s can now be instantiated from markup streams, in addition
to strings and file-like objects (ticket #69).
* Improve handling of incorrectly nested tags in the HTML parser.
* Template includes can now be nested inside fallback content.
* Expressions can now contain dict literals (ticket #37).
* It is now possible to have one or more escaped dollar signs in front of a
full expression (ticket #92).
* The `Markup` class is now available by default in template expressions
(ticket #67).
* The handling of namespace declarations in XML/XHTML output has been improved.
* The `Attrs` class no longer automatically wraps all attribute names in
`QName` objects. This is now the responsibility of whoever is instantiating
`Attrs` objects (for example, stream filters and generators).
* Python code blocks are now supported using the `` processing
instruction (ticket #84).
* The way errors in template expressions are handled can now be configured. The
option `LenientLookup` provides the same forgiving mode used in previous
Genshi versions, while `StrictLookup` raises exceptions when undefined
variables or members are accessed. The lenient mode is still the default in
this version, but that may change in the future. (ticket #88)
* If a variable is not necessarily defined at the top level of the template
data, the new built-in functions `defined(key)` and `value_of(key, default)`
can be used so that the template also works in strict lookup mode. These
functions were previously only available when using Genshi via the template
engine plugin (for compatibility with Kid).
* `style` attributes are no longer allowed by the `HTMLSanitizer` by default.
If they are explicitly added to the set of safe attributes, any unicode
escapes in the attribute value are now handled properly.
* Namespace declarations on conditional elements (for example using a `py:if`
directive`) are no longer moved to the following element when the element
originally carrying the declaration is removed from the stream (ticket #107).
* Added basic built-in support for internationalizing templates by providing
a new `Translator` class that can both extract localizable strings from a
stream, and replace those strings with their localizations at render time.
The code for this was largely taken from previous work done by Matt Good
and David Fraser.
Version 0.3.6
http://svn.edgewall.org/repos/genshi/tags/0.3.6/
(Dec 11 2006, from branches/stable/0.3.x)
* The builder API now accepts streams as children of elements and fragments.
Version 0.3.5
http://svn.edgewall.org/repos/genshi/tags/0.3.5/
(Nov 22 2006, from branches/stable/0.3.x)
* Fix XPath traversal in match templates. Previously, `div/p` would be treated
the same as `div//p`, i.e. it would match all descendants and not just the
immediate children.
* Preserve whitespace in HTML `` elements also when they contain child
elements.
* Match templates no longer match their own output (ticket #77).
* Blank lines before directives in text templates are now preserved as
expected (ticket #62).
Version 0.3.4
http://svn.edgewall.org/repos/genshi/tags/0.3.4/
(Nov 2 2006, from branches/stable/0.3.x)
* The encoding of HTML and XML files, as well as markup and text templates,
can now be specified. Also, the encoding specified in XML declarations is
now respected unless an expiclit encoding is requested.
* Expressions used as arguments for `py:with`, `py:def`, and `py:for`
directives can now contain non-ASCII strings.
Version 0.3.3
http://svn.edgewall.org/repos/genshi/tags/0.3.3/
(Oct 16 2006, from branches/stable/0.3.x)
* Fixed bug introduced in 0.3.2 that broke the parsing of templates which
declare the same namespace more than once in a nested fashion.
* Fixed the parsing of HTML entity references inside attribute values, both
in the `XMLParser` and the `HTMLParser` classes.
* Some changes to usage of absolute vs. relative template paths to ensure that
the filenamed-keyed cache employed by the TemplateLoader doesn't mix up
templates with the same name, but from different subdirectories.
Version 0.3.2
http://svn.edgewall.org/repos/genshi/tags/0.3.2/
(Oct 12 2006, from branches/stable/0.3.x)
* Exceptions from templates now contain the absolute path to the template file
when a search path is used. This enables tracebacks to display the line in
question.
* The template engine plugin now provides three different types: "genshi" and
"genshi-markup" map to markup templates, while "genshi-text" maps to text
templates.
* Fixed the namespace context used by XPath patterns in py:match templates.
The were erroneously using the namespace context of the elements being
matched, where they should rather use the context in which they were
defined.
* The contents of `
