Changelog

1.0.7

:released: Thu Jul 13 2017

.. change:: :tags: bug

Changed the &quot;print&quot; in the mako-render command to
sys.stdout.write(), avoiding the extra newline at the end
of the template output.  Pull request courtesy
Yves Chevallier.

.. changelog::

1.0.6

:released: Wed Nov 9 2016

.. change:: :tags: feature

 Added new parameter :paramref:`.Template.include_error_handler` .
 This works like :paramref:`.Template.error_handler` but indicates the
 handler should take place when this template is included within another
 template via the ``&lt;%include&gt;`` tag.  Pull request courtesy
 Huayi Zhang.

.. changelog::

1.0.5

:released: Wed Nov 2 2016

.. change:: :tags: bug

 Updated the Sphinx documentation builder to work with recent
 versions of Sphinx.

.. changelog::

1.0.4

:released: Thu Mar 10 2016

.. change:: :tags: feature, test

 The default test runner is now py.test.  Running &quot;python setup.py test&quot;
 will make use of py.test instead of nose.  nose still works as a test
 runner as well, however.

.. change:: :tags: bug, lexer :pullreq: github:19

 Major improvements to lexing of intricate Python sections which may
 contain complex backslash sequences, as well as support for the bitwise
 operator (e.g. pipe symbol) inside of expression sections distinct
 from the Mako &quot;filter&quot; operator, provided the operator is enclosed
 within parentheses or brackets.  Pull request courtesy Daniel Martin.

.. change:: :tags: feature :pullreq: bitbucket:16

 Added new method :meth:`.Template.list_defs`.   Pull request courtesy
 Jonathan Vanasco.

.. changelog::

1.0.3

:released: Tue Oct 27 2015

.. change:: :tags: bug, babel :pullreq: bitbucket:21

 Fixed an issue where the Babel plugin would not handle a translation
 symbol that contained non-ascii characters.  Pull request courtesy
 Roman Imankulov.

.. changelog::

1.0.2

:released: Wed Aug 26 2015

.. change:: :tags: bug, installation :tickets: 249

 The &quot;universal wheel&quot; marker is removed from setup.cfg, because
 our setup.py currently makes use of conditional dependencies.
 In :ticket:`249`, the discussion is ongoing on how to correct our
 setup.cfg / setup.py fully so that we can handle the per-version
 dependency changes while still maintaining optimal wheel settings,
 so this issue is not yet fully resolved.

.. change:: :tags: bug, py3k :tickets: 250

 Repair some calls within the ast module that no longer work on Python3.5;
 additionally replace the use of ``inspect.getargspec()`` under
 Python 3 (seems to be called from the TG plugin) to avoid deprecation
 warnings.

.. change:: :tags: bug :pullreq: bitbucket:18

 Update the Lingua translation extraction plugin to correctly
 handle templates mixing Python control statements (such as if,
 for and while) with template fragments. Pull request courtesy
 Laurent Daverio.

.. change:: :tags: feature :tickets: 236

 Added ``STOP_RENDERING`` keyword for returning/exiting from a
 template early, which is a synonym for an empty string ``&quot;&quot;``.
 Previously, the docs suggested a bare
 ``return``, but this could cause ``None`` to appear in the
 rendered template result.

 .. seealso::

   :ref:`syntax_exiting_early`

.. changelog::

1.0.1

:released: Thu Jan 22 2015

.. change:: :tags: feature :pullreq: bitbucket:9

 Added support for Lingua, a translation extraction system as an
 alternative to Babel.  Pull request courtesy Wichert Akkerman.

.. change:: :tags: bug, py3k :pullreq: bitbucket:11

 Modernized the examples/wsgi/run_wsgi.py file for Py3k.
 Pull requset courtesy Cody Taylor.

.. changelog::

1.0.0

:released: Sun Jun 8 2014

.. change:: :tags: bug, py2k :pullreq: bitbucket:8

 Improved the error re-raise operation when a custom
 :paramref:`.Template.error_handler` is used that does not handle
 the exception; the original stack trace etc. is now preserved.
 Pull request courtesy Manfred Haltner.

.. change:: :tags: bug, py2k, filters :pullreq: bitbucket:7

 Added an html_escape filter that works in &quot;non unicode&quot; mode.
 Previously, when using ``disable_unicode=True``, the ``u`` filter
 would fail to handle non-ASCII bytes properly.  Pull request
 courtesy George Xie.

.. change:: :tags: general

 Compatibility changes; in order to modernize the codebase, Mako
 is now dropping support for Python 2.4 and Python 2.5 altogether.
 The source base is now targeted at Python 2.6 and forwards.

.. change:: :tags: feature

 Template modules now generate a JSON &quot;metadata&quot; structure at the bottom
 of the source file which includes parseable information about the
 templates&#39; source file, encoding etc. as well as a mapping of module
 source lines to template lines, thus replacing the &quot; SOURCE LINE&quot;
 markers throughout the source code.  The structure also indicates those
 lines that are explicitly not part of the template&#39;s source; the goal
 here is to allow better integration with coverage and other tools.

.. change:: :tags: bug, py3k

 Fixed bug in ``decode.&lt;encoding&gt;`` filter where a non-string object
 would not be correctly interpreted in Python 3.

.. change:: :tags: bug, py3k :tickets: 227

 Fixed bug in Python parsing logic which would fail on Python 3
 when a &quot;try/except&quot; targeted a tuple of exception types, rather
 than a single exception.

.. change:: :tags: feature :pullreq: bitbucket:5

 mako-render is now implemented as a setuptools entrypoint script;
 a standalone mako.cmd.cmdline() callable is now available, and the
 system also uses argparse now instead of optparse.  Pull request
 courtesy Derek Harland.

.. change:: :tags: feature :pullreq: bitbucket:4

 The mako-render script will now catch exceptions and run them
 into the text error handler, and exit with a non-zero exit code.
 Pull request courtesy Derek Harland.

.. change:: :tags: bug :pullreq: bitbucket:2

 A rework of the mako-render script allows the script to run
 correctly when given a file pathname that is outside of the current
 directory, e.g. ``mako-render ../some_template.mako``.  In this case,
 the &quot;template root&quot; defaults to the directory in which the template
 is located, instead of &quot;.&quot;.  The script also accepts a new argument
 ``--template-dir`` which can be specified multiple times to establish
 template lookup directories.  Standard input for templates also works
 now too.  Pull request courtesy Derek Harland.

.. change:: :tags: feature, py3k :pullreq: github:7

 Support is added for Python 3 &quot;keyword only&quot; arguments, as used in
 defs.  Pull request courtesy Eevee.

0.9

.. changelog::

0.9.1

:released: Thu Dec 26 2013

.. change:: :tags: bug :tickets: 225

 Fixed bug in Babel plugin where translator comments
 would be lost if intervening text nodes were encountered.
 Fix courtesy Ned Batchelder.

.. change:: :tags: bug :tickets:

 Fixed TGPlugin.render method to support unicode template
 names in Py2K - courtesy Vladimir Magamedov.

.. change:: :tags: bug :tickets:

 Fixed an AST issue that was preventing correct operation
 under alpha versions of Python 3.4.  Pullreq courtesy Zer0-.

.. change:: :tags: bug :tickets:

 Changed the format of the &quot;source encoding&quot; header output
 by the code generator to use the format `` -*- coding:%s -*-``
 instead of `` -*- encoding:%s -*-``; the former is more common
 and compatible with emacs.  Courtesy Martin Geisler.

.. change:: :tags: bug :tickets: 224

 Fixed issue where an old lexer rule prevented a template line
 which looked like &quot;*&quot; from being correctly parsed.

.. changelog::

0.9.0

:released: Tue Aug 27 2013

.. change:: :tags: bug :tickets: 219

 The Context.locals_() method becomes a private underscored
 method, as this method has a specific internal use. The purpose
 of Context.kwargs has been clarified, in that it only delivers
 top level keyword arguments originally passed to template.render().

.. change:: :tags: bug :tickets:

 Fixed the babel plugin to properly interpret ${} sections
 inside of a &quot;call&quot; tag, i.e. &lt;%self:some_tag attr=&quot;${_(&#39;foo&#39;)}&quot;/&gt;.
 Code that&#39;s subject to babel escapes in here needs to be
 specified as a Python expression, not a literal.  This change
 is backwards incompatible vs. code that is relying upon a _(&#39;&#39;)
 translation to be working within a call tag.

.. change:: :tags: bug :tickets: 187

 The Babel plugin has been repaired to work on Python 3.

.. change:: :tags: bug :tickets: 207

 Using &lt;%namespace import=&quot;*&quot; module=&quot;somemodule&quot;/&gt; now
 skips over module elements that are not explcitly callable,
 avoiding TypeError when trying to produce partials.

.. change:: :tags: bug :tickets: 190

 Fixed Py3K bug where a &quot;lambda&quot; expression was not
 interpreted correctly within a template tag; also
 fixed in Py2.4.

0.8

.. changelog::

0.8.1

:released: Fri May 24 2013

.. change:: :tags: bug :tickets: 216

 Changed setup.py to skip installing markupsafe
 if Python version is &lt; 2.6 or is between 3.0 and
 less than 3.3, as Markupsafe now only supports 2.6-&gt;2.X,
 3.3-&gt;3.X.

.. change:: :tags: bug :tickets: 214

 Fixed regression where &quot;entity&quot; filter wasn&#39;t
 converted for py3k properly (added tests.)

.. change:: :tags: bug :tickets: 212

 Fixed bug where mako-render script wasn&#39;t
 compatible with Py3k.

.. change:: :tags: bug :tickets: 213

 Cleaned up all the various deprecation/
 file warnings when running the tests under
 various Pythons with warnings turned on.

.. changelog::

0.8.0

:released: Wed Apr 10 2013

.. change:: :tags: feature :tickets:

 Performance improvement to the
 &quot;legacy&quot; HTML escape feature, used for XML
 escaping and when markupsafe isn&#39;t present,
 courtesy George Xie.

.. change:: :tags: bug :tickets: 209

 Fixed bug whereby an exception in Python 3
 against a module compiled to the filesystem would
 fail trying to produce a RichTraceback due to the
 content being in bytes.

.. change:: :tags: bug :tickets: 208

 Change default for compile()-&gt;reserved_names
 from tuple to frozenset, as this is expected to be
 a set by default.

.. change:: :tags: feature :tickets:

 Code has been reworked to support Python 2.4-&gt;
 Python 3.xx in place.  2to3 no longer needed.

.. change:: :tags: feature :tickets:

 Added lexer_cls argument to Template,
 TemplateLookup, allows alternate Lexer classes
 to be used.

.. change:: :tags: feature :tickets:

 Added future_imports parameter to Template
 and TemplateLookup, renders the __future__ header
 with desired capabilities at the top of the generated
 template module.  Courtesy Ben Trofatter.

0.7

.. changelog::

0.7.3

:released: Wed Nov 7 2012

.. change:: :tags: bug :tickets:

 legacy_html_escape function, used when
 Markupsafe isn&#39;t installed, was using an inline-compiled
 regexp which causes major slowdowns on Python 3.3;
 is now precompiled.

.. change:: :tags: bug :tickets: 201

 AST supporting now supports tuple-packed
 function arguments inside pure-python def
 or lambda expressions.

.. change:: :tags: bug :tickets:

 Fixed Py3K bug in the Babel extension.

.. change:: :tags: bug :tickets:

 Fixed the &quot;filter&quot; attribute of the
 &lt;%text&gt; tag so that it pulls locally specified
 identifiers from the context the same
 way as that of &lt;%block&gt; and &lt;%filter&gt;.

.. change:: :tags: bug :tickets:

 Fixed bug in plugin loader to correctly
 raise exception when non-existent plugin
 is specified.

.. changelog::

0.7.2

:released: Fri Jul 20 2012

.. change:: :tags: bug :tickets: 193

 Fixed regression in 0.7.1 where AST
 parsing for Py2.4 was broken.

.. changelog::

0.7.1

:released: Sun Jul 8 2012

.. change:: :tags: feature :tickets: 146

 Control lines with no bodies will
 now succeed, as &quot;pass&quot; is added for these
 when no statements are otherwise present.
 Courtesy Ben Trofatter

.. change:: :tags: bug :tickets: 192

 Fixed some long-broken scoping behavior
 involving variables declared in defs and such,
 which only became apparent when
 the strict_undefined flag was turned on.

.. change:: :tags: bug :tickets: 191

 Can now use strict_undefined at the
 same time args passed to def() are used
 by other elements of the &lt;%def&gt; tag.

.. changelog::

0.7.0

:released: Fri Mar 30 2012

.. change:: :tags: feature :tickets: 125

 Added new &quot;loop&quot; variable to templates,
 is provided within a % for block to provide
 info about the loop such as index, first/last,
 odd/even, etc.  A migration path is also provided
 for legacy templates via the &quot;enable_loop&quot; argument
 available on Template, TemplateLookup, and &lt;%page&gt;.
 Thanks to Ben Trofatter for all
 the work on this

.. change:: :tags: feature :tickets:

 Added a real check for &quot;reserved&quot;
 names, that is names which are never pulled
 from the context and cannot be passed to
 the template.render() method.  Current names
 are &quot;context&quot;, &quot;loop&quot;, &quot;UNDEFINED&quot;.

.. change:: :tags: feature :tickets: 95

 The html_error_template() will now
 apply Pygments highlighting to the source
 code displayed in the traceback, if Pygments
 if available.  Courtesy Ben Trofatter

.. change:: :tags: feature :tickets: 147

 Added support for context managers,
 i.e. &quot;% with x as e:/ % endwith&quot; support.
 Courtesy Ben Trofatter

.. change:: :tags: feature :tickets: 185

 Added class-level flag to CacheImpl
 &quot;pass_context&quot;; when True, the keyword argument
 &#39;context&#39; will be passed to get_or_create()
 containing the Mako Context object.

.. change:: :tags: bug :tickets: 182

 Fixed some Py3K resource warnings due
 to filehandles being implicitly closed.

.. change:: :tags: bug :tickets: 186

 Fixed endless recursion bug when
 nesting multiple def-calls with content.
 Thanks to Jeff Dairiki.

.. change:: :tags: feature :tickets:

 Added Jinja2 to the example
 benchmark suite, courtesy Vincent FÃ©rotin

Older Versions

.. changelog::

0.6.2

:released: Thu Feb 2 2012

.. change:: :tags: bug :tickets: 86, 20

 The ${{&quot;foo&quot;:&quot;bar&quot;}} parsing issue is fixed!!
 The legendary Eevee has slain the dragon!.  Also fixes quoting issue
 at.

.. changelog::

0.6.1

:released: Sat Jan 28 2012

.. change:: :tags: bug :tickets:

 Added special compatibility for the 0.5.0
 Cache() constructor, which was preventing file
 version checks and not allowing Mako 0.6 to
 recompile the module files.

.. changelog::

0.6.0

:released: Sat Jan 21 2012

.. change:: :tags: feature :tickets:

 Template caching has been converted into a plugin
 system, whereby the usage of Beaker is just the
 default plugin.   Template and TemplateLookup
 now accept a string &quot;cache_impl&quot; parameter which
 refers to the name of a cache plugin, defaulting
 to the name &#39;beaker&#39;.  New plugins can be
 registered as pkg_resources entrypoints under
 the group &quot;mako.cache&quot;, or registered directly
 using mako.cache.register_plugin().  The
 core plugin is the mako.cache.CacheImpl
 class.

.. change:: :tags: feature :tickets:

 Added support for Beaker cache regions
 in templates.   Usage of regions should be considered
 as superseding the very obsolete idea of passing in
 backend options, timeouts, etc. within templates.

.. change:: :tags: feature :tickets:

 The &#39;put&#39; method on Cache is now
 &#39;set&#39;.  &#39;put&#39; is there for backwards compatibility.

.. change:: :tags: feature :tickets:

 The &lt;%def&gt;, &lt;%block&gt; and &lt;%page&gt; tags now accept
 any argument named &quot;cache_*&quot;, and the key
 minus the &quot;cache_&quot; prefix will be passed as keyword
 arguments to the CacheImpl methods.

.. change:: :tags: feature :tickets:

 Template and TemplateLookup now accept an argument
 cache_args, which refers to a dictionary containing
 cache parameters.  The cache_dir, cache_url, cache_type,
 cache_timeout arguments are deprecated (will probably
 never be removed, however) and can be passed
 now as cache_args={&#39;url&#39;:&lt;some url&gt;, &#39;type&#39;:&#39;memcached&#39;,
 &#39;timeout&#39;:50, &#39;dir&#39;:&#39;/path/to/some/directory&#39;}

.. change:: :tags: feature/bug :tickets: 180

 Can now refer to context variables
 within extra arguments to &lt;%block&gt;, &lt;%def&gt;, i.e.
 &lt;%block name=&quot;foo&quot; cache_key=&quot;${somekey}&quot;&gt;.
 Filters can also be used in this way, i.e.
 &lt;%def name=&quot;foo()&quot; filter=&quot;myfilter&quot;&gt;
 then template.render(myfilter=some_callable)

.. change:: :tags: feature :tickets: 178

 Added &quot;--var name=value&quot; option to the mako-render
 script, allows passing of kw to the template from
 the command line.

.. change:: :tags: feature :tickets: 181

 Added module_writer argument to Template,
 TemplateLookup, allows a callable to be passed which
 takes over the writing of the template&#39;s module source
 file, so that special environment-specific steps
 can be taken.

.. change:: :tags: bug :tickets: 142

 The exception message in the html_error_template
 is now escaped with the HTML filter.

.. change:: :tags: bug :tickets: 173

 Added &quot;white-space:pre&quot; style to html_error_template()
 for code blocks so that indentation is preserved

.. change:: :tags: bug :tickets: 175

 The &quot;benchmark&quot; example is now Python 3 compatible
 (even though several of those old template libs aren&#39;t
 available on Py3K, so YMMV)

.. changelog::

0.5.0

:released: Wed Sep 28 2011

.. change:: :tags: :tickets: 174

 A Template is explicitly disallowed
 from having a url that normalizes to relative outside
 of the root.   That is, if the Lookup is based
 at /home/mytemplates, an include that would place
 the ultimate template at
 /home/mytemplates/../some_other_directory,
 i.e. outside of /home/mytemplates,
 is disallowed.   This usage was never intended
 despite the lack of an explicit check.
 The main issue this causes
 is that module files can be written outside
 of the module root (or raise an error, if file perms aren&#39;t
 set up), and can also lead to the same template being
 cached in the lookup under multiple, relative roots.
 TemplateLookup instead has always supported multiple
 file roots for this purpose.

.. changelog::

0.4.2

:released: Fri Aug 5 2011

.. change:: :tags: :tickets: 170

 Fixed bug regarding &lt;%call&gt;/def calls w/ content
 whereby the identity of the &quot;caller&quot; callable
 inside the &lt;%def&gt; would be corrupted by the
 presence of another &lt;%call&gt; in the same block.

.. change:: :tags: :tickets: 169

 Fixed the babel plugin to accommodate &lt;%block&gt;

.. changelog::

0.4.1

:released: Wed Apr 6 2011

.. change:: :tags: :tickets: 164

 New tag: &lt;%block&gt;.  A variant on &lt;%def&gt; that
 evaluates its contents in-place.
 Can be named or anonymous,
 the named version is intended for inheritance
 layouts where any given section can be
 surrounded by the &lt;%block&gt; tag in order for
 it to become overrideable by inheriting
 templates, without the need to specify a
 top-level &lt;%def&gt; plus explicit call.
 Modified scoping and argument rules as well as a
 more strictly enforced usage scheme make it ideal
 for this purpose without at all replacing most
 other things that defs are still good for.
 Lots of new docs.

.. change:: :tags: :tickets: 165

 a slight adjustment to the &quot;highlight&quot; logic
 for generating template bound stacktraces.
 Will stick to known template source lines
 without any extra guessing.

.. changelog::

0.4.0

:released: Sun Mar 6 2011

.. change:: :tags: :tickets:

 A 20% speedup for a basic two-page
 inheritance setup rendering
 a table of escaped data
 (see http://techspot.zzzeek.org/2010/11/19/quick-mako-vs.-jinja-speed-test/).
 A few configurational changes which
 affect those in the I-don&#39;t-do-unicode
 camp should be noted below.

.. change:: :tags: :tickets:

 The FastEncodingBuffer is now used
 by default instead of cStringIO or StringIO,
 regardless of whether output_encoding
 is set to None or not.  FEB is faster than
 both.  Only StringIO allows bytestrings
 of unknown encoding to pass right
 through, however - while it is of course
 not recommended to send bytestrings of unknown
 encoding to the output stream, this
 mode of usage can be re-enabled by
 setting the flag bytestring_passthrough
 to True.

.. change:: :tags: :tickets:

 disable_unicode mode requires that
 output_encoding be set to None - it also
 forces the bytestring_passthrough flag
 to True.

.. change:: :tags: :tickets: 156

 the &lt;%namespace&gt; tag raises an error
 if the &#39;template&#39; and &#39;module&#39; attributes
 are specified at the same time in
 one tag.  A different class is used
 for each case which allows a reduction in
 runtime conditional logic and function
 call overhead.

.. change:: :tags: :tickets: 159

 the keys() in the Context, as well as
 it&#39;s internal _data dictionary, now
 include just what was specified to
 render() as well as Mako builtins
 &#39;caller&#39;, &#39;capture&#39;.  The contents
 of __builtin__ are no longer copied.
 Thanks to Daniel Lopez for pointing
 this out.

.. changelog::

0.3.6

:released: Sat Nov 13 2010

.. change:: :tags: :tickets: 126

 Documentation is on Sphinx.

.. change:: :tags: :tickets: 154

 Beaker is now part of &quot;extras&quot; in
 setup.py instead of &quot;install_requires&quot;.
 This to produce a lighter weight install
 for those who don&#39;t use the caching
 as well as to conform to Pyramid
 deployment practices.

.. change:: :tags: :tickets: 153

 The Beaker import (or attempt thereof)
 is delayed until actually needed;
 this to remove the performance penalty
 from startup, particularly for
 &quot;single execution&quot; environments
 such as shell scripts.

.. change:: :tags: :tickets: 155

 Patch to lexer to not generate an empty
 &#39;&#39; write in the case of backslash-ended
 lines.

.. change:: :tags: :tickets: 148

 Fixed missing **extra collection in
 setup.py which prevented setup.py
 from running 2to3 on install.

.. change:: :tags: :tickets:

 New flag on Template, TemplateLookup -
 strict_undefined=True, will cause
 variables not found in the context to
 raise a NameError immediately, instead of
 defaulting to the UNDEFINED value.

.. change:: :tags: :tickets:

 The range of Python identifiers that
 are considered &quot;undefined&quot;, meaning they
 are pulled from the context, has been
 trimmed back to not include variables
 declared inside of expressions (i.e. from
 list comprehensions), as well as
 in the argument list of lambdas.  This
 to better support the strict_undefined
 feature.  The change should be
 fully backwards-compatible but involved
 a little bit of tinkering in the AST code,
 which hadn&#39;t really been touched for
 a couple of years, just FYI.

.. changelog::

0.3.5

:released: Sun Oct 24 2010

.. change:: :tags: :tickets: 141

 The &lt;%namespace&gt; tag allows expressions
 for the `file` argument, i.e. with ${}.
 The `context` variable, if needed,
 must be referenced explicitly.

.. change:: :tags: :tickets:

 ${} expressions embedded in tags,
 such as &lt;%foo:bar x=&quot;${...}&quot;&gt;, now
 allow multiline Python expressions.

.. change:: :tags: :tickets:

 Fixed previously non-covered regular
 expression, such that using a ${} expression
 inside of a tag element that doesn&#39;t allow
 them raises a CompileException instead of
 silently failing.

.. change:: :tags: :tickets: 151

 Added a try/except around &quot;import markupsafe&quot;.
 This to support GAE which can&#39;t run markupsafe. No idea whatsoever if the
 install_requires in setup.py also breaks GAE,
 couldn&#39;t get an answer on this.

.. changelog::

0.3.4

:released: Tue Jun 22 2010

.. change:: :tags: :tickets:

 Now using MarkupSafe for HTML escaping,
 i.e. in place of cgi.escape().  Faster
 C-based implementation and also escapes
 single quotes for additional security.
 Supports the __html__ attribute for
 the given expression as well.

 When using &quot;disable_unicode&quot; mode,
 a pure Python HTML escaper function
 is used which also quotes single quotes.

 Note that Pylons by default doesn&#39;t
 use Mako&#39;s filter - check your
 environment.py file.

.. change:: :tags: :tickets: 137

 Fixed call to &quot;unicode.strip&quot; in
 exceptions.text_error_template which
 is not Py3k compatible.

.. changelog::

0.3.3

:released: Mon May 31 2010

.. change:: :tags: :tickets: 135

 Added conditional to RichTraceback
 such that if no traceback is passed
 and sys.exc_info() has been reset,
 the formatter just returns blank
 for the &quot;traceback&quot; portion.

.. change:: :tags: :tickets: 131

 Fixed sometimes incorrect usage of
 exc.__class__.__name__
 in html/text error templates when using
 Python 2.4

.. change:: :tags: :tickets:

 Fixed broken property decorator on
 template.last_modified

.. change:: :tags: :tickets: 132

 Fixed error formatting when a stacktrace
 line contains no line number, as in when
 inside an eval/exec-generated function.

.. change:: :tags: :tickets:

 When a .py is being created, the tempfile
 where the source is stored temporarily is
 now made in the same directory as that of
 the .py file.  This ensures that the two
 files share the same filesystem, thus
 avoiding cross-filesystem synchronization
 issues.  Thanks to Charles Cazabon.

.. changelog::

0.3.2

:released: Thu Mar 11 2010

.. change:: :tags: :tickets: 116

 Calling a def from the top, via
 template.get_def(...).render() now checks the
 argument signature the same way as it did in
 0.2.5, so that TypeError is not raised.

0.3.0

:released: Fri Mar 5 2010

.. change:: :tags: :tickets: 123

 Python 2.3 support is dropped.

.. change:: :tags: :tickets: 119

 Python 3 support is added ! See README.py3k
 for installation and testing notes.

.. change:: :tags: :tickets: 127

 Unit tests now run with nose.

.. change:: :tags: :tickets: 99

 Source code escaping has been simplified.
 In particular, module source files are now
 generated with the Python &quot;magic encoding
 comment&quot;, and source code is passed through
 mostly unescaped, except for that code which
 is regenerated from parsed Python source.
 This fixes usage of unicode in
 &lt;%namespace:defname&gt; tags.

.. change:: :tags: :tickets: 122

 RichTraceback(), html_error_template().render(),
 text_error_template().render() now accept &quot;error&quot;
 and &quot;traceback&quot; as optional arguments, and
 these are now actually used.

.. change:: :tags: :tickets:

 The exception output generated when
 format_exceptions=True will now be as a Python
 unicode if it occurred during render_unicode(),
 or an encoded string if during render().

.. change:: :tags: :tickets: 112

 A percent sign can be emitted as the first
 non-whitespace character on a line by escaping
 it as in &quot;%%&quot;.

.. change:: :tags: :tickets: 94

 Template accepts empty control structure, i.e.
 % if: %endif, etc.

.. change:: :tags: :tickets: 116

 The &lt;%page args&gt; tag can now be used in a base
 inheriting template - the full set of render()
 arguments are passed down through the inherits
 chain.  Undeclared arguments go into **pageargs
 as usual.

.. change:: :tags: :tickets: 109

 defs declared within a &lt;%namespace&gt; section, an
 uncommon feature, have been improved.  The defs
 no longer get doubly-rendered in the body() scope,
 and now allow local variable assignment without
 breakage.

.. change:: :tags: :tickets: 128

 Windows paths are handled correctly if a Template
 is passed only an absolute filename (i.e. with c:
 drive etc.)  and no URI - the URI is converted
 to a forward-slash path and module_directory
 is treated as a windows path.

.. change:: :tags: :tickets: 73

 TemplateLookup raises TopLevelLookupException for
 a given path that is a directory, not a filename,
 instead of passing through to the template to
 generate IOError.

.. changelog:: :version: 0.2.6 :released:

.. change:: :tags: :tickets:

 Fix mako function decorators to preserve the
 original function&#39;s name in all cases. Patch
 from Scott Torborg.

.. change:: :tags: :tickets: 118

 Support the &lt;%namespacename:defname&gt; syntax in
 the babel extractor.

.. change:: :tags: :tickets: 88

 Further fixes to unicode handling of .py files with the
 html_error_template.

.. changelog::

0.2.5

:released: Mon Sep 7 2009

.. change:: :tags: :tickets:

 Added a &quot;decorator&quot; kw argument to &lt;%def&gt;,
 allows custom decoration functions to wrap
 rendering callables.  Mainly intended for
 custom caching algorithms, not sure what
 other uses there may be (but there may be).
 Examples are in the &quot;filtering&quot; docs.

.. change:: :tags: :tickets: 101

 When Mako creates subdirectories in which
 to store templates, it uses the more
 permissive mode of 0775 instead of 0750,
 helping out with certain multi-process
 scenarios. Note that the mode is always
 subject to the restrictions of the existing
 umask.

.. change:: :tags: :tickets: 104

 Fixed namespace.__getattr__() to raise
 AttributeError on attribute not found
 instead of RuntimeError.

.. change:: :tags: :tickets: 97

 Added last_modified accessor to Template,
 returns the time.time() when the module
 was created.

.. change:: :tags: :tickets: 102

 Fixed lexing support for whitespace
 around &#39;=&#39; sign in defs.

.. change:: :tags: :tickets: 108

 Removed errant &quot;lower()&quot; in the lexer which
 was causing tags to compile with
 case-insensitive names, thus messing up
 custom &lt;%call&gt; names.

.. change:: :tags: :tickets: 110

 added &quot;mako.__version__&quot; attribute to
 the base module.

.. changelog::

0.2.4

:released: Tue Dec 23 2008

.. change:: :tags: :tickets:

 Fixed compatibility with Jython 2.5b1.

.. changelog::

0.2.3

:released: Sun Nov 23 2008

.. change:: :tags: :tickets:

 the &lt;%namespacename:defname&gt; syntax described at
 http://techspot.zzzeek.org/?p=28 has now
 been added as a built in syntax, and is recommended
 as a more modern syntax versus &lt;%call expr=&quot;expression&quot;&gt;.
 The %call tag itself will always remain,
 with &lt;%namespacename:defname&gt; presenting a more HTML-like
 alternative to calling defs, both plain and
 nested.  Many examples of the new syntax are in the
 &quot;Calling a def with embedded content&quot; section
 of the docs.

.. change:: :tags: :tickets:

 added support for Jython 2.5.

.. change:: :tags: :tickets:

 cache module now uses Beaker&#39;s CacheManager
 object directly, so that all cache types are included.
 memcached is available as both &quot;ext:memcached&quot; and
 &quot;memcached&quot;, the latter for backwards compatibility.

.. change:: :tags: :tickets:

 added &quot;cache&quot; accessor to Template, Namespace.
 e.g.  ${local.cache.get(&#39;somekey&#39;)} or
 template.cache.invalidate_body()

.. change:: :tags: :tickets:

 added &quot;cache_enabled=True&quot; flag to Template,
 TemplateLookup.  Setting this to False causes cache
 operations to &quot;pass through&quot; and execute every time;
 this flag should be integrated in Pylons with its own
 cache_enabled configuration setting.

.. change:: :tags: :tickets: 92

 the Cache object now supports invalidate_def(name),
 invalidate_body(), invalidate_closure(name),
 invalidate(key), which will remove the given key
 from the cache, if it exists.  The cache arguments
 (i.e. storage type) are derived from whatever has
 been already persisted for that template.

.. change:: :tags: :tickets:

 For cache changes to work fully, Beaker 1.1 is required.
 1.0.1 and up will work as well with the exception of
 cache expiry.  Note that Beaker 1.1 is **required**
 for applications which use dynamically generated keys,
 since previous versions will permanently store state in memory
 for each individual key, thus consuming all available
 memory for an arbitrarily large number of distinct
 keys.

.. change:: :tags: :tickets: 93

 fixed bug whereby an &lt;%included&gt; template with
 &lt;%page&gt; args named the same as a __builtin__ would not
 honor the default value specified in &lt;%page&gt;

.. change:: :tags: :tickets: 88

 fixed the html_error_template not handling tracebacks from
 normal .py files with a magic encoding comment

.. change:: :tags: :tickets:

 RichTraceback() now accepts an optional traceback object
 to be used in place of sys.exc_info()[2].  html_error_template()
 and text_error_template() accept an optional
 render()-time argument &quot;traceback&quot; which is passed to the
 RichTraceback object.

.. change:: :tags: :tickets:

 added ModuleTemplate class, which allows the construction
 of a Template given a Python module generated by a previous
 Template.   This allows Python modules alone to be used
 as templates with no compilation step.   Source code
 and template source are optional but allow error reporting
 to work correctly.

.. change:: :tags: :tickets: 90

 fixed Python 2.3 compat. in mako.pyparser

.. change:: :tags: :tickets:

 fix Babel 0.9.3 compatibility; stripping comment tags is now
 optional (and enabled by default).

.. changelog::

0.2.2

:released: Mon Jun 23 2008

.. change:: :tags: :tickets: 87

 cached blocks now use the current context when rendering
 an expired section, instead of the original context
 passed in

.. change:: :tags: :tickets:

 fixed a critical issue regarding caching, whereby
 a cached block would raise an error when called within a
 cache-refresh operation that was initiated after the
 initiating template had completed rendering.

.. changelog::

0.2.1

:released: Mon Jun 16 2008

.. change:: :tags: :tickets:

 fixed bug where &#39;output_encoding&#39; parameter would prevent
 render_unicode() from returning a unicode object.

.. change:: :tags: :tickets:

 bumped magic number, which forces template recompile for
 this version (fixes incompatible compile symbols from 0.1
 series).

.. change:: :tags: :tickets:

 added a few docs for cache options, specifically those that
 help with memcached.

.. changelog::

0.2.0

:released: Tue Jun 3 2008

.. change:: :tags: :tickets:

 Speed improvements (as though we needed them, but people
 contributed and there you go):

.. change:: :tags: :tickets: 77

 added &quot;bytestring passthru&quot; mode, via
 `disable_unicode=True` argument passed to Template or
 TemplateLookup. All unicode-awareness and filtering is
 turned off, and template modules are generated with
 the appropriate magic encoding comment. In this mode,
 template expressions can only receive raw bytestrings
 or Unicode objects which represent straight ASCII, and
 render_unicode() may not be used if multibyte
 characters are present. When enabled, speed
 improvement around 10-20%. (courtesy
 anonymous guest)

.. change:: :tags: :tickets: 76

 inlined the &quot;write&quot; function of Context into a local
 template variable. This affords a 12-30% speedup in
 template render time. (idea courtesy same anonymous
 guest)

.. change:: :tags: :tickets:

 New Features, API changes:

.. change:: :tags: :tickets: 62

 added &quot;attr&quot; accessor to namespaces. Returns
 attributes configured as module level attributes, i.e.
 within &lt;%! %&gt; sections.  i.e.:

  somefile.html
 &lt;%!
     foo = 27
 %&gt;

  some other template
 &lt;%namespace name=&quot;myns&quot; file=&quot;somefile.html&quot;/&gt;
 ${myns.attr.foo}

 The slight backwards incompatibility here is, you
 can&#39;t have namespace defs named &quot;attr&quot; since the
 &quot;attr&quot; descriptor will occlude it.

.. change:: :tags: :tickets: 78

 cache_key argument can now render arguments passed
 directly to the %page or %def, i.e. &lt;%def
 name=&quot;foo(x)&quot; cached=&quot;True&quot; cache_key=&quot;${x}&quot;/&gt;

.. change:: :tags: :tickets:

 some functions on Context are now private:
 _push_buffer(), _pop_buffer(),
 caller_stack._push_frame(), caller_stack._pop_frame().

.. change:: :tags: :tickets: 56, 81

 added a runner script &quot;mako-render&quot; which renders
 standard input as a template to stdout

.. change:: :tags: bugfixes :tickets: 83, 84

 can now use most names from __builtins__ as variable
 names without explicit declaration (i.e. &#39;id&#39;,
 &#39;exception&#39;, &#39;range&#39;, etc.)

.. change:: :tags: bugfixes :tickets: 84

 can also use builtin names as local variable names
 (i.e. dict, locals) (came from fix for)

.. change:: :tags: bugfixes :tickets: 68

 fixed bug in python generation when variable names are
 used with identifiers like &quot;else&quot;, &quot;finally&quot;, etc.
 inside them

.. change:: :tags: bugfixes :tickets: 69

 fixed codegen bug which occurred when using &lt;%page&gt;
 level caching, combined with an expression-based
 cache_key, combined with the usage of &lt;%namespace
 import=&quot;*&quot;/&gt; - fixed lexer exceptions not cleaning up
 temporary files, which could lead to a maximum number
 of file descriptors used in the process

.. change:: :tags: bugfixes :tickets: 71

 fixed issue with inline format_exceptions that was
 producing blank exception pages when an inheriting
 template is present

.. change:: :tags: bugfixes :tickets:

 format_exceptions will apply the encoding options of
 html_error_template() to the buffered output

.. change:: :tags: bugfixes :tickets: 75

 rewrote the &quot;whitespace adjuster&quot; function to work
 with more elaborate combinations of quotes and
 comments

.. changelog::

0.1.10

:released:

.. change:: :tags: :tickets:

 fixed propagation of &#39;caller&#39; such that nested %def calls
 within a &lt;%call&gt; tag&#39;s argument list propigates &#39;caller&#39;
 to the %call function itself (propigates to the inner
 calls too, this is a slight side effect which previously
 existed anyway)

.. change:: :tags: :tickets:

 fixed bug where local.get_namespace() could put an
 incorrect &quot;self&quot; in the current context

.. change:: :tags: :tickets:

 fixed another namespace bug where the namespace functions
 did not have access to the correct context containing
 their &#39;self&#39; and &#39;parent&#39;

.. changelog::

0.1.9

:released:

.. change:: :tags: :tickets: 47

 filters.Decode filter can also accept a non-basestring
 object and will call str() + unicode() on it

.. change:: :tags: :tickets: 53

 comments can be placed at the end of control lines,
 i.e. if foo:  a comment,, thanks to
 Paul Colomiets

.. change:: :tags: :tickets: 16

 fixed expressions and page tag arguments and with embedded
 newlines in CRLF templates, follow up to, thanks
 Eric Woroshow

.. change:: :tags: :tickets: 51

 added an IOError catch for source file not found in RichTraceback
 exception reporter

.. changelog::

0.1.8

:released: Tue Jun 26 2007

.. change:: :tags: :tickets:

 variable names declared in render methods by internal
 codegen prefixed by &quot;__M_&quot; to prevent name collisions
 with user code

.. change:: :tags: :tickets: 45

 added a Babel (http://babel.edgewall.org/) extractor entry
 point, allowing extraction of gettext messages directly from
 mako templates via Babel

.. change:: :tags: :tickets:

 fix to turbogears plugin to work with dot-separated names
 (i.e. load_template(&#39;foo.bar&#39;)).  also takes file extension
 as a keyword argument (default is &#39;mak&#39;).

.. change:: :tags: :tickets: 35

 more tg fix:  fixed, allowing string-based
 templates with tgplugin even if non-compatible args were sent

.. changelog::

0.1.7

:released: Wed Jun 13 2007

.. change:: :tags: :tickets:

 one small fix to the unit tests to support python 2.3

.. change:: :tags: :tickets:

 a slight hack to how cache.py detects Beaker&#39;s memcached,
 works around unexplained import behavior observed on some
 python 2.3 installations

.. changelog::

0.1.6

:released: Fri May 18 2007

.. change:: :tags: :tickets:

 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.

.. change:: :tags: :tickets: 34

 fix to module_directory path generation when the path is &quot;./&quot;

.. change:: :tags: :tickets: 35

 TGPlugin passes options to string-based templates

.. change:: :tags: :tickets: 28

 added an explicit stack frame step to template runtime, which
 allows much simpler and hopefully bug-free tracking of &#39;caller&#39;,
 fixes

.. change:: :tags: :tickets:

 if plain Python defs are used with &lt;%call&gt;, a decorator
 runtime.supports_callable exists to ensure that the &quot;caller&quot;
 stack is properly handled for the def.

.. change:: :tags: :tickets: 37

 fix to RichTraceback and exception reporting to get template
 source code as a unicode object

.. change:: :tags: :tickets: 39

 html_error_template includes options &quot;full=True&quot;, &quot;css=True&quot;
 which control generation of HTML tags, CSS

.. change:: :tags: :tickets: 40

 added the &#39;encoding_errors&#39; parameter to Template/TemplateLookup
 for specifying the error handler associated with encoding to
 &#39;output_encoding&#39;

.. change:: :tags: :tickets: 37

 the Template returned by html_error_template now defaults to
 output_encoding=sys.getdefaultencoding(),
 encoding_errors=&#39;htmlentityreplace&#39;

.. change:: :tags: :tickets:

 control lines, i.e. % lines, support backslashes to continue long
 lines (32)

 AST expression generation - added in just about everything
 expression-wise from the AST module

.. change:: :tags: :tickets: 27

 AST parsing, properly detects imports of the form &quot;import foo.bar&quot;

.. change:: :tags: :tickets:

 fix to lexing of &lt;%docs&gt; tag nested in other tags

.. change:: :tags: :tickets: 29

 fix to context-arguments inside of &lt;%include&gt; tag which broke
 during 0.1.4

.. change:: :tags: :tickets:

 added &quot;n&quot; filter, disables *all* filters normally applied to an expression
 via &lt;%page&gt; or default_filters (but not those within the filter)

.. change:: :tags: :tickets:

 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 &quot;opt out&quot; of that filtering
 via passing special attributes or objects.

.. changelog::

0.1.4

:released: Sat Mar 10 2007

.. change:: :tags: :tickets:

 got defs-within-defs to be cacheable

 fixes to code parsing/whitespace adjusting where plain python comments
 may contain quote characters

.. change:: :tags: :tickets:

 fix to variable scoping for identifiers only referenced within
 functions

.. change:: :tags: :tickets:

 added a path normalization step to lookup so URIs like
 &quot;/foo/bar/../etc/../foo&quot; pre-process the &quot;..&quot; tokens before checking
 the filesystem

.. change:: :tags: :tickets:

 fixed/improved &quot;caller&quot; semantics so that undefined caller is
 &quot;UNDEFINED&quot;, 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

.. change:: :tags: :tickets:

 &lt;%include&gt; has an &quot;args&quot; attribute that can pass arguments to the
 called template (keyword arguments only, must be declared in that
 page&#39;s &lt;%page&gt; tag.)

.. change:: :tags: :tickets:

 &lt;%include&gt; plus arguments is also programmatically available via
 self.include_file(&lt;filename&gt;, **kwargs)

.. change:: :tags: :tickets: 24

 further escaping added for multibyte expressions in %def, %call
 attributes

.. changelog::

0.1.3

:released: Wed Feb 21 2007

.. change:: :tags: :tickets:

 ***Small Syntax Change*** - the single line comment character is now
 *two* hash signs, i.e. &quot; this is a comment&quot;.  This avoids a common
 collection with CSS selectors.

.. change:: :tags: :tickets:

 the magic &quot;coding&quot; comment (i.e.  coding:utf-8) will still work with
 either one &quot;&quot; sign or two for now; two is preferred going forward, i.e.
  coding:&lt;someencoding&gt;.

 added &quot;preprocessor&quot; 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.

.. change:: :tags: :tickets:

 added mako.ext.preprocessors package, contains one preprocessor so far:
 &#39;convert_comments&#39;, which will convert single  comments to the new 
 format

.. changelog::

0.1.2

:released: Thu Feb 1 2007

.. change:: :tags: :tickets: 11

 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

.. change:: :tags: :tickets:

 all template lexing converts the template to unicode first, to
 immediately catch any encoding issues and ensure internal unicode
 representation.

.. change:: :tags: :tickets:

 added module_filename argument to Template to allow specification of a
 specific module file

.. change:: :tags: :tickets: 14

 added modulename_callable to TemplateLookup to allow a function to
 determine module filenames (takes filename, uri arguments). used for

.. change:: :tags: :tickets:

 added optional input_encoding flag to Template, to allow sending a
 unicode() object with no magic encoding comment

.. change:: :tags: :tickets:

 &quot;expression_filter&quot; argument in &lt;%page&gt; applies only to expressions

.. change:: :tags: "unicode" :tickets:

 added &quot;default_filters&quot; argument to Template, TemplateLookup. applies only
 to expressions, gets prepended to &quot;expression_filter&quot; arg from &lt;%page&gt;.
 defaults to, so that all expressions get stringified into u&#39;&#39;
 by default (this is what Mako already does). By setting to [], expressions
 are passed through raw.

.. change:: :tags: :tickets:

 added &quot;imports&quot; 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.

.. change:: :tags: :tickets:

 small fix to local variable propigation for locals that are conditionally
 declared
