mako-inheritance / CHANGES

- fixed propagation of 'caller' such that nested %def calls
  within a <%call> tag's argument list propigates 'caller'
  to the %call function itself (propigates to the inner
  calls too, this is a slight side effect which previously
  existed anyway)
- fixed bug where local.get_namespace() could put an 
  incorrect "self" in the current context
- fixed another namespace bug where the namespace functions
  did not have access to the correct context containing
  their 'self' and 'parent'
- filters.Decode filter can also accept a non-basestring
object and will call str() + unicode() on it [ticket:47]
- comments can be placed at the end of control lines,
i.e. if foo: # a comment, [ticket:53], thanks to 
Paul Colomiets
- fixed expressions and page tag arguments and with embedded
newlines in CRLF templates, follow up to [ticket:16], thanks
Eric Woroshow
- added an IOError catch for source file not found in RichTraceback
exception reporter [ticket:51]

- variable names declared in render methods by internal 
codegen prefixed by "__M_" to prevent name collisions
with user code
- added a Babel ( extractor entry
point, allowing extraction of gettext messages directly from
mako templates via Babel [ticket:45]
- fix to turbogears plugin to work with dot-separated names
(i.e. load_template('')).  also takes file extension
as a keyword argument (default is 'mak').
- more tg fix:  fixed [ticket:35], allowing string-based
templates with tgplugin even if non-compatible args were sent

- one small fix to the unit tests to support python 2.3
- a slight hack to how detects Beaker's memcached, 
works around unexplained import behavior observed on some 
python 2.3 installations

- caching is now supplied directly by Beaker, which has 
  all of MyghtyUtils merged into it now.  The latest Beaker
  (0.7.1) also fixes a bug related to how Mako was using the 
  cache API.
- fix to module_directory path generation when the path is "./"
- TGPlugin passes options to string-based templates [ticket:35]
- added an explicit stack frame step to template runtime, which
  allows much simpler and hopefully bug-free tracking of 'caller',
  fixes #28
- if plain Python defs are used with <%call>, a decorator
  @runtime.supports_callable exists to ensure that the "caller"
  stack is properly handled for the def.
- fix to RichTraceback and exception reporting to get template
  source code as a unicode object #37
- html_error_template includes options "full=True", "css=True"
  which control generation of HTML tags, CSS [ticket:39]
- added the 'encoding_errors' parameter to Template/TemplateLookup
  for specifying the error handler associated with encoding to
  'output_encoding' [ticket:40]
- the Template returned by html_error_template now defaults to
  encoding_errors='htmlentityreplace' [ticket:37]
- control lines, i.e. % lines, support backslashes to continue long
  lines (#32)
- fixed codegen bug when defining <%def> within <%call> within <%call>
- leading utf-8 BOM in template files is honored according to pep-0263
- AST expression generation - added in just about everything 
  expression-wise from the AST module  [ticket:26]
- AST parsing, properly detects imports of the form "import"
- fix to lexing of <%docs> tag nested in other tags
- fix to context-arguments inside of <%include> tag which broke 
during 0.1.4 [ticket:29]
- added "n" filter, disables *all* filters normally applied to an expression
via <%page> or default_filters (but not those within the filter)
- added buffer_filters argument, defines filters applied to the return value
of buffered/cached/filtered %defs, after all filters defined with the %def
itself have been applied.  allows the creation of default expression filters
that let the output of return-valued %defs "opt out" of that filtering
via passing special attributes or objects.
- got defs-within-defs to be cacheable
- fixes to code parsing/whitespace adjusting where plain python comments
  may contain quote characters [ticket:23]
- fix to variable scoping for identifiers only referenced within
- added a path normalization step to lookup so URIs like
  "/foo/bar/../etc/../foo" pre-process the ".." tokens before checking
  the filesystem
- fixed/improved "caller" semantics so that undefined caller is
  "UNDEFINED", propigates __nonzero__ method so it evaulates to False if
  not present, True otherwise. this way you can say % if caller:\n
  ${caller.body()}\n% endif
- <%include> has an "args" attribute that can pass arguments to the
  called template (keyword arguments only, must be declared in that
  page's <%page> tag.)
- <%include> plus arguments is also programmatically available via
  self.include_file(<filename>, **kwargs)
- further escaping added for multibyte expressions in %def, %call
  attributes [ticket:24]

- ***Small Syntax Change*** - the single line comment character is now
*two* hash signs, i.e. "## this is a comment".  This avoids a common
collection with CSS selectors. 
- the magic "coding" comment (i.e. # coding:utf-8) will still work with
either one "#" sign or two for now; two is preferred going forward, i.e.
## coding:<someencoding>. 
- new multiline comment form: "<%doc> a comment </%doc>"
- UNDEFINED evaluates to False
- improvement to scoping of "caller" variable when using <%call> tag
- added lexer error for unclosed control-line (%) line
- added "preprocessor" argument to Template, TemplateLookup - is a single
  callable or list of callables which will be applied to the template text
  before lexing.  given the text as an argument, returns the new text.
- added mako.ext.preprocessors package, contains one preprocessor so far:
  'convert_comments', which will convert single # comments to the new ##
- fix to parsing of code/expression blocks to insure that non-ascii
  characters, combined with a template that indicates a non-standard
  encoding, are expanded into backslash-escaped glyphs before being AST
  parsed [ticket:11]
- all template lexing converts the template to unicode first, to
  immediately catch any encoding issues and ensure internal unicode
- added module_filename argument to Template to allow specification of a
  specific module file
- added modulename_callable to TemplateLookup to allow a function to
  determine module filenames (takes filename, uri arguments). used for
- added optional input_encoding flag to Template, to allow sending a
  unicode() object with no magic encoding comment
- "expression_filter" argument in <%page> applies only to expressions
- added "default_filters" argument to Template, TemplateLookup. applies only
  to expressions, gets prepended to "expression_filter" arg from <%page>.
  defaults to ["unicode"], so that all expressions get stringified into u''
  by default (this is what Mako already does). By setting to [], expressions
  are passed through raw.
- added "imports" argument to Template, TemplateLookup. so you can predefine
  a list of import statements at the top of the template. can be used in
  conjunction with default_filters.
- support for CRLF templates...whoops ! welcome to all the windows users.
- small fix to local variable propigation for locals that are conditionally
- got "top level" def calls to work, i.e. template.get_def("somedef").render()

- buffet plugin supports string-based templates, allows ToscaWidgets to work
- AST parsing fixes: fixed TryExcept identifier parsing
- removed textmate tmbundle from contrib and into separate SVN location;
  windows users cant handle those files, setuptools not very good at
  "pruning" certain directories
- fix so that "cache_timeout" parameter is propigated
- fix to expression filters so that string conversion (actually unicode)
  properly occurs before filtering
- better error message when a lookup is attempted with a template that has no
- implemented "module" attribute for namespace
- fix to code generation to correctly track multiple defs with the same name
- "directories" can be passed to TemplateLookup as a scalar in which case it
  gets converted to a list [ticket:9]


Initial release.
