Handlebars now supports subexpressions.

{{foo (bar 3)}}

Subexpressions are always evaluated as helpers; if
3 were omitted from the above example, bar would be invoked as a
param-less helper, even though a top-levell {{bar}} would be considered
ambiguous.

The return value of a subexpression helper is passed in as a parameter of a
parent subexpression helper, even in string params mode. Their type, as
listed in options.types or options.hashTypes in string params mode, is
"sexpr".

The main conceptual change in the Handlebars code is that there is a new
AST.SexprNode that manages the params/hash passed into a mustache, as well as
the logic that governs whether that mustache is a helper invocation, property
lookup, etc. MustacheNode, which used to manage this stuff, still exists, but
only manages things like white-space stripping and whether the mustache is
escaped or not. So, a MustacheNode has a SexprNode.

The introduction of subexpressions is fully backwards compatible, but a few
things needed to change about the compiled output of a template in order to
support subexpressions. The main one is that the options hash is no longer
stashed in a local options var before being passed to either the helper
being invoked or the
helperMissing fallback. Rather, the options object is inlined in these
cases. This does mean compiled template sizes will be a little bit larger,
even those that don't make use of subexpressions, but shouldn't have any
noticeable impact on performance when actually rendering templates as only
one of these inlined objects will actually get evaluated.

It adds coverage to something that broke during my code reorg, specific to ambiguous block helper invocations only in string mode. Is there a better name or something more meaningful I could put in the description?

This is fine, I wasn't sure that it was related to string mode etc. For my own curiosity, how was the code failing when it broke?

Illegal JS code was generated in the template with stack-1 and stack-2 references showing up because I was missing a few pushStacks in the ambiguous block helper code path.

I think this generally looks awesome. Thanks for doing the work on this! Any thoughts on user-facing documentation for this feature?

Handlebars now supports subexpressions.

    {{foo (bar 3)}}

Subexpressions are always evaluated as helpers; if
`3` were omitted from the above example, `bar`
would be invoked as a param-less helper, even
though a top-levell `{{bar}}` would be considered
ambiguous.

The return value of a subexpression helper is
passed in as a parameter of a parent subexpression
helper, even in string params mode. Their type,
as listed in `options.types` or `options.hashTypes`
in string params mode, is "sexpr".

The main conceptual change in the Handlebars code
is that there is a new AST.SexprNode that manages
the params/hash passed into a mustache, as well
as the logic that governs whether that mustache
is a helper invocation, property lookup, etc.
MustacheNode, which used to manage this stuff,
still exists, but only manages things like
white-space stripping and whether the mustache
is escaped or not. So, a MustacheNode _has_
a SexprNode.

The introduction of subexpressions is fully
backwards compatible, but a few things needed
to change about the compiled output of a template
in order to support subexpressions. The main one
is that the options hash is no longer stashed in
a local `options` var before being passed to
either the helper being invoked or the
`helperMissing` fallback. Rather, the options
object is inlined in these cases. This does
mean compiled template sizes will be a little
bit larger, even those that don't make use of
subexpressions, but shouldn't have any noticeable
impact on performance when actually rendering
templates as only one of these inlined objects
will actually get evaluated.

An impressive bit of work done on this. I was iffy on the use of "logic" within templates in general, but I think this strikes a nice balance.

- Expose escapeExpression on the root object - 980c38c
- Remove nested function eval in blockHelperMissing - 6f22ec1
- Fix compiler program de-duping - 9e3f824

Compatibility notes:
- The default build now outputs a generic UMD wrapper. This should be transparent change but may cause issues in some environments.
- Runtime compatibility breaks in both directions. Ensure that both compiler and client are upgraded to 2.0.0-beta.1 or higher at the same time.
  - `programWithDepth` has been removed an instead an array of context values is passed to fields needing depth lookups.
- `false` values are now printed to output rather than silently dropped
- Lines containing only block statements and whitespace are now removed. This matches the Mustache spec but may cause issues with code that expects whitespace to exist but would not otherwise.
- Partials that are standalone will now indent their rendered content
- `AST.ProgramNode`'s signature has changed.
- Numerious methods/features removed from psuedo-API classes
  - `JavaScriptCompiler.register`
  - `JavaScriptCompiler.replaceStack` no longer supports non-inline replace
  - `Compiler.disassemble`
  - `DECLARE` opcode
  - `strip` opcode
  - `lookup` opcode
  - Content nodes may have their `string` values mutated over time. `original` field provides the unmodified value.
- Removed unused `Handlebars.registerHelper` `inverse` parameter
- `each` helper requires iterator parameter

- Temporarily kill the AWS publish CI step - 8347ee2

Compatibility notes:
- A JSON polyfill is required to run the compiler under IE8 and below. It's recommended that the precompiler be used in lieu of running the compiler on these legacy environments.

- `JavaScriptCompiler.compilerInfo` now returns generic objects rather than javascript source.
- AST changes
  - INTEGER -> NUMBER

[Commits](handlebars-lang/handlebars.js@v1.1.0...v1.1.1)

## v1.1.0 - November 3rd, 2013

- [#628](handlebars-lang/handlebars.js#628) - Convert code to ES6 modules ([@kpdecker](https://api.github.com/users/kpdecker))
- [#336](handlebars-lang/handlebars.js#336) - Add whitespace control syntax ([@kpdecker](https://api.github.com/users/kpdecker))
- [#535](handlebars-lang/handlebars.js#535) - Fix for probable JIT error under Safari ([@sorentwo](https://api.github.com/users/sorentwo))
- [#483](handlebars-lang/handlebars.js#483) - Add first and last @ vars to each helper ([@denniskuczynski](https://api.github.com/users/denniskuczynski))
- [#557](handlebars-lang/handlebars.js#557) - `\\{{foo}}` escaping only works in some situations ([@dmarcotte](https://api.github.com/users/dmarcotte))
- [#552](handlebars-lang/handlebars.js#552) - Added BOM removal flag. ([@blessenm](https://api.github.com/users/blessenm))
- [#543](handlebars-lang/handlebars.js#543) - publish passing master builds to s3 ([@fivetanley](https://api.github.com/users/fivetanley))

- [#608](handlebars-lang/handlebars.js#608) - Add `includeZero` flag to `if` conditional
- [#498](handlebars-lang/handlebars.js#498) - `Handlebars.compile` fails on empty string although a single blank works fine
- [#599](handlebars-lang/handlebars.js#599) - lambda helpers only receive options if used with arguments
- [#592](handlebars-lang/handlebars.js#592) - Optimize array and subprogram performance
- [#571](handlebars-lang/handlebars.js#571) - uglify upgrade breaks compatibility with older versions of node
- [#587](handlebars-lang/handlebars.js#587) - Partial inside partial breaks?

Compatibility notes:
- The project now includes separate artifacts for AMD, CommonJS, and global objects.
  - AMD: Users may load the bundled `handlebars.amd.js` or `handlebars.runtime.amd.js` files or load individual modules directly. AMD users should also note that the handlebars object is exposed via the `default` field on the imported object. This [gist](https://gist.github.com/wycats/7417be0dc361a69d5916) provides some discussion of possible compatibility shims.
  - CommonJS/Node: Node loading occurs as normal via `require`
  - Globals: The `handlebars.js` and `handlebars.runtime.js` files should behave in the same manner as the v1.0.12 / 1.0.0 release.
- Build artifacts have been removed from the repository. [npm][npm], [components/handlebars.js][components], [cdnjs][cdnjs], or the [builds page][builds-page] should now be used as the source of built artifacts.
- Context-stored helpers are now always passed the `options` hash. Previously no-argument helpers did not have this argument.

## v1.0.12 / 1.0.0 - May 31 2013

- [#515](handlebars-lang/handlebars.js#515) - Add node require extensions support ([@jjclark1982](https://github.com/jjclark1982))
- [#517](handlebars-lang/handlebars.js#517) - Fix amd precompiler output with directories ([@blessenm](https://github.com/blessenm))
- [#433](handlebars-lang/handlebars.js#433) - Add support for unicode ids
- [#469](handlebars-lang/handlebars.js#469) - Add support for `?` in ids
- [#534](handlebars-lang/handlebars.js#534) - Protect from object prototype modifications
- [#519](handlebars-lang/handlebars.js#519) - Fix partials with . name ([@jamesgorrie](https://github.com/jamesgorrie))
- [#519](handlebars-lang/handlebars.js#519) - Allow ID or strings in partial names
- [#437](handlebars-lang/handlebars.js#437) - Require matching brace counts in escaped expressions
- Merge passed partials and helpers with global namespace values
- Add support for complex ids in @DaTa references
- Docs updates

Compatibility notes:
- The parser is now stricter on `{{{`, requiring that the end token be `}}}`. Templates that do not
  follow this convention should add the additional brace value.
- Code that relies on global the namespace being muted when custom helpers or partials are passed will need to explicitly pass an `undefined` value for any helpers that should not be available.
- The compiler version has changed. Precompiled templates with 1.0.12 or higher must use the 1.0.0 or higher runtime.
