• Add support for python-style array slices with Jinja compat enabled. Fixes #188; merge of #976.

• Fix call blocks having access to their parent scope. Fixes #906; merge of #994.

• Fix a bug that caused capturing block tags (e.g. set/endset, filter/endfilter) to write to the global buffer rather than capturing their contents. Fixes #914 and #972; merge of #990. Thanks Noah Lange.

3.0.0 (Nov 5 2016)

• Allow including many templates without reaching recursion limits. Merge of #787. Thanks Gleb Khudyakov.

• Execute blocks in a child frame that can't write to its parent. This means that vars set inside blocks will not leak outside of the block, base templates can no longer see vars set in templates that inherit them, and super() can no longer set vars in its calling scope. Fixes the inheritance portion of #561, which fully closes that issue. Thanks legutierr for the report.

• Prevent macros from seeing or affecting their calling scope. Merge of #667.

• Ensure that precompiling on Windows still outputs POSIX-style path separators. Merge of #761.

• Add support for strict type check comparisons (=== and !==). Thanks oughter. Merge of #746.

• Allow full expressions (incl. filters) in import and from tags. Thanks legutierr. Merge of #710.

• OS agnostic file paths in precompile. Merge of #825.

2.4.0 (Mar 10 2016)

• Allow retrieving boolean-false as a global. Thanks Marius Büscher. Merge of #694.

• Don't automatically convert any for-loop that has an include statement into an async loop. Reverts 7d4716f4fd, re-opens #372, fixes #527. Thanks Tom Delmas for the report.

• Switch from Optimist to Yargs for argument-parsing. Thanks Bogdan Chadkin. Merge of #672.

• Prevent includes from writing to their including scope. Merge of #667 (only partially backported to 2.x; macro var visibility not backported).

• Fix handling of dev environment option, to get full tracebacks on errors (including nunjucks internals). Thanks Tobias Petry and Chandrasekhar Ambula V for the report, Aleksandr Motsjonov for draft patch.

• Support using in operator to search in both arrays and objects, and it will throw an error for other data types. Fix #659. Thanks Alex Mayfield for report and test, Ouyang Yadong for fix. Merge of #661.

• Fix whitespace control around nested tags/variables/comments. Thanks Ouyang Yadong. Merge of #631.

v2.3.0 (Jan 6 2016)

• Return null from WebLoader on missing template instead of throwing an error, for consistency with other loaders. This allows WebLoader to support the new ignore missing flag on the include tag. If ignore missing is not set, a generic "template not found" error will still be thrown, just like for any other loader. Ajax errors other than 404 will still cause WebLoader to throw an error directly.

• Add preserve-linebreaks option to striptags filter. Thanks Ivan Kleshnin. Merge of #619.

v2.2.0 (Nov 23 2015)

• Add striptags filter. Thanks Anthony Giniers. Merge of #589.

• Add support for chaining of addGlobal, addFilter, etc. Thanks Rob Graeber. Merge of #537
• Fix error propagation. Thanks Tom Delmas. Merge of #534.
• trimBlocks now also trims windows style line endings. Thanks Magnus Tovslid. Merge of #548
• include now supports an option to suppress errors if the template does not exist. Thanks Mathias Nestler. Merge of #559

• Fix creating WebLoader without opts. Merge of #524.
• Add hasExtension and removeExtension methods to Environment. Merge of #512.

• Add support for keyword arguments for sort filter. Thanks Andres Pardini. Merge of #510

v2.0.0 (Aug 30 2015)

Most of the changes can be summed up in the issues tagged 2.0.

Or you can see all commits.

Most important changes:

• autoescape is now on by default. You need to explicitly pass { autoescape: false } in the options to turn it off.
• watch is off by default. You need to explicitly pass { watch: true } to start the watcher.
• The default filter has changed. It will show the default value only if the argument is undefined. Any other value, even false-y values like false and null, will be returned. You can get back the old behavior by passing true as a 3rd argument to activate the loose-y behavior: foo | default("bar", true). In 2.0 if you don't pass the 3rd argument, a warning will be displayed about this change in behavior. In 2.1 this warning will be removed.
• New filter tag
• Lots of other bug fixes and small features, view the above issue list!

v1.3.4 (Apr 27 2015)

This is an extremely minor release that only adds an .npmignore so that the bench, tests, and docs folders do not get published to npm. Nunjucks should download a lot faster now.

v1.3.3 (Apr 3 2015)

This is exactly the same as v1.3.1, just fixing a typo in the git version tag.

v1.3.2 (Apr 3 2015)

(no notes)

v1.3.1 (Apr 3 2015)

We added strict mode to all the files, but that broke running nunjucks in the browser. Should work now with this small fix.

v1.3.0 (Apr 3 2015)

• Relative templates: you can now load a template relatively by starting the path with ., like ./foo.html
• FileSystemLoader now takes a noCache option, if true will disable caching entirely
• Additional lstripBlocks and trimBlocks available to clean output automatically
• New selectattr and rejectattr filters
• Small fixes to the watcher
• Several bug fixes

v1.2.0 (Feb 4 2015)

• The special non-line-breaking space is considered whitespace now
• The in operator has a lower precedence now. This is potentially a breaking change, thus the minor version bump. See #336
• import with context now implemented: #319
• async rendering doesn't throw compile errors

v1.1.0 (Sep 30 2014)

User visible changes:

• Fix a bug in urlize that would remove periods
• custom tag syntax (like {% and %}) was made Environment-specific internally. Previously they were global even though you set them through the Environment.
• Remove aggressive optimization that only emitted loop variables when uses. It introduced several bugs and didn't really improve perf.
• Support the regular expression syntax like /foo/g.
• The replace filter can take a regex as the first argument
• The call tag was implemented
• for tags can now take an else clause
• The cycler object now exposes the current item as the current property
• The chokidar library was updated and should fix various issues

Dev changes:

• Test coverage now available via istanbul. Will automatically display after running tests.

v1.0.7 (Aug 15 2014)

Mixed up a few things in the 1.0.6 release, so another small bump. This merges in one thing:

• The length filter will not throw an error is used on an undefined variable. It will return 0 if the variable is undefined.

v1.0.6 (Aug 15 2014)

• Added the addGlobal method to the Environment object
• import/extends/include now can take an arbitrary expression
• fix bugs in set
• improve express integration (allows rendering templates without an extension)

v1.0.5 (May 1 2014)

• Added support for browserify
• Added option to specify template output path when precompiling templates
• Keep version comment in browser minified files
• Speed up SafeString implementation
• Handle null and non-matching cases for word count filter
• Added support for node-webkit
• Other various minor bugfixes

chokidar repo fix - v1.0.4 (Apr 4 2014)

• The chokidar dependency moved repos, and though the git URL should have been forwarded some people were having issues. This fixed the repo and version.

(v1.0.3 is skipped because it was published with a bad URL, quickly fixed with another version bump)

Bug fixes - v1.0.2 (Mar 25 2014)

• Use chokidar for watching file changes. This should fix a lot of problems on OS X machines.
• Always use / in paths when precompiling templates
• Fix bug where async filters hang indefinitely inside if statements
• Extensions now can override autoescaping with an autoescape property
• Other various minor bugfixes

v1.0.1 (Dec 16, 2013)

(no notes)

We've reached 1.0! Better APIs, asynchronous control, and more (Oct 24, 2013)

• An asynchronous API is now available, and async filters, extensions, and loaders is supported. The async API is optional and if you don't do anything async (the default), nothing changes for you. You can read more about this here. (fixes #41)
• Much simpler higher-level API for initiating/configuring nunjucks is available. Read more here.
• An official grunt plugin is available for precompiling templates: grunt-nunjucks
• The browser files have been renamed. nunjucks.js is now the full library with compiler, and nunjucks-slim.js is the small version that only works with precompiled templates
• urlencode filter has been added
• The express integration has been refactored and isn't a kludge anymore. Should avoid some bugs and be more future-proof;
• The order in which variables are lookup up in the context and frame lookup has been reversed. It will now look in the frame first, and then the context. This means that if a for loop introduces a new var, like {% for name in names %}, and if you have name in the context as well, it will properly reference name from the for loop inside the loop. (fixes #122 and #119)

v0.1.10 (Aug 9 2013)

(no notes)

v0.1.9 (May 30 2013)

(no notes)

v0.1.8 - whitespace controls, unpacking, better errors, and more! (Feb 6 2013)

There are lots of cool new features in this release, as well as many critical bug fixes.

Full list of changes:

• Whitespace control is implemented. Use {%- and -%} to strip whitespace before/after the block.

• for loops implement Python-style array unpacking. This is a really nice feature which lets you do this:

  {% for x, y, z in [[2, 2, 2], [3, 3, 3]] %} --{{ x }} {{ y }} {{ z }}-- {% endfor %}

  The above would output: --2 2 2----3 3 3--

  You can pass any number of variable names to for and it will destructure each array in the list to the variables.

  This makes the syntax between arrays and objects more consistent. Additionally, it allows us to implement the dictsort filter which sorts an object by keys or values. Technically, it returns an array of 2-value arrays and the unpacking takes care of it. Example:

  {% for k, v in { b: 2, a: 1 } %} --{{ k }}: {{ v }}-- {% endfor %}

  Output: --b: 2----a: 1-- (note: the order could actually be anything because it uses javascript’s for k in obj syntax to iterate, and ordering depends on the js implementation)

  {% for k, v in { b: 2, a: 1} | dictsort %} --{{ k }}: {{ v }}-- {% endfor %}

  Output: --a: 1----b: 2--

  The above output will always be ordered that way. See the documentation for more details.

  Thanks to novocaine for this!

• Much better error handling with at runtime (shows template/line/col information for attempting to call undefined values, etc)

• Fixed a regression which broke the {% raw %} block

• Fix some edge cases with variable lookups

• Fix a regression with loading precompiled templates

• Tweaks to allow usage with YUICompressor

• Use the same error handling as normal when precompiling (shows proper errors)

• Fix template loading on Windows machines

• Fix int/float filters

• Fix regression with super()

v0.1.7 - helpful errors, many bug fixes (Dec 12 2012)

The biggest change in v0.1.7 comes from devoidfury (thanks!) which implements consistent and helpful error messages. The errors are still simply raw text, and not pretty HTML, but they at least contain all the necessary information to track down an error, such as template names, line and column numbers, and the inheritance stack. So if an error happens in a child template, it will print out all the templates that it inherits. In the future, we will most likely display the actual line causing an error.

Full list of changes:

• Consistent and helpful error messages
• Expressions are more consistent now. Previously, there were several places that wouldn’t accept an arbitrary expression that should. For example, you can now do {% include templateNames['foo'] %}, whereas previously you could only give it a simply variable name.
• app.locals is fixed with express 2.5
• Method calls on objects now have correct scope for this. Version 0.1.6 broke this and this was referencing the global scope.
• A check was added to enforce loading of templates within the correct path. Previously you could load a file outside of the template with something like ../../crazyPrivateFile.txt

You can view all the code changes here. Please file an issue if something breaks!

v0.1.6 - undefined handling, bugfixes (Nov 13, 2012)

This is mostly a bugfix release, but there are a few small tweaks based on feedback:

• In some cases, backslashes in the template would not appear in the output. This has been fixed.
• An error is thrown if a filter is not found
• Old versions of express are now supported (2.5.11 was tested)
• References on undefined objects are now suppressed. For example, {{ foo }}, {{ foo.bar }}, {{ foo.bar.baz }} all output nothing if foo is undefined. Previously only the first form would be suppressed, and a cryptic error thrown for the latter 2 references. Note: I believe this is a departure from jinja, which throws errors when referencing undefined objects. I feel that this is a good and non-breaking addition though. (thanks to devoidfury)
• A bug in set where you couldn’t not reference other variables is fixed (thanks chriso and panta)
• Other various small bugfixes

You can view all the code changes here. As always, file an issue if something breaks!

v0.1.5 - macros, keyword arguments, bugfixes (Oct 11 2012)

v0.1.5 has been pushed to npm, and it’s a big one. Please file any issues you find, and I’ll fix them as soon as possible!

• The node data structure has been completely refactored to reduce redundancy and make it easier to add more types in the future.
• Thanks to Brent Hagany, macros now have been implemented. They should act exactly the way jinja2 macros do.
• A calling convention which implements keyword arguments now exists. All keyword args are converted into a hash and passed as the last argument. Macros needed this to implement keyword/default arguments.
• Function and filter calls apply the new keyword argument calling convention
• The “set” block now appropriately only sets a variable for the current scope.
• Many other bugfixes.

I’m watching this release carefully because of the large amount of code that has changed, so please file an issue if you have a problem with it.
