Nils Knappmeier 088e61812a chore: add eslint-plugin-compat and eslint-plugin-es5
- tests are not compiled with babel and must thus be in
  es5
- we don't use polyfills, so we need to make sure no
  functions aren't used that are not supported by popular browsers. (like Object.assign in Safari and IE11)
- Boths are errors that usually only appear when running
  tests in SauceLabs, which happens only on _after_
  merging a PR.

Robert Jackson 62ed3c25c7 Add Handlebars.parseWithoutProcessing (#1584)
When authoring tooling that parses Handlebars files and emits Handlebars
files, you often want to preserve the **exact** formatting of the input.
The changes in this commit add a new method to the `Handlebars`
namespace: `parseWithoutProcessing`. Unlike, `Handlebars.parse` (which
will mutate the parsed AST to apply whitespace control) this method will
parse the template and return it directly (**without** processing
😉).

For example, parsing the following template:

```hbs
 {{#foo}}
   {{~bar~}} {{baz~}}
 {{/foo}}
```

Using `Handlebars.parse`, the AST returned would have truncated the
following whitespace:

* The whitespace prior to the `{{#foo}}`
* The newline following `{{#foo}}`
* The leading whitespace before `{{~bar~}}`
* The whitespace between `{{~bar~}}` and `{{baz~}}`
* The newline after `{{baz~}}`
* The whitespace prior to the `{{/foo}}`

When `Handlebars.parse` is used from  `Handlebars.precompile` or
`Handlebars.compile`, this whitespace stripping is **very** important
(these behaviors are intentional, and generally lead to better rendered
output).

When the same template is parsed with
`Handlebars.parseWithoutProcessing` none of those modifications to the
AST are made. This enables "codemod tooling" (e.g. `prettier` and
`ember-template-recast`) to preserve the **exact** initial formatting.
Prior to these changes, those tools would have to _manually_ reconstruct
the whitespace that is lost prior to emitting source.

Nils Knappmeier fd2e5c983d fix: non-eager matching raw-block-contents
In 4.4.4 the block-contents was matched with an eager match, which means
that with multiple raw-blocks of the same kind, the block was spanned
over the first ending-tag until the last one.
This commit replaces this by a non-eager match.

antelle cf7545ef5a Added support for iterable objects in {{#each}} helper (#1557)
* Added support for iterable object in {{#each}} helper
Currently {{#each}} helper supports either arrays, or objects,
however nowadays you can define custom iterable objects by overriding
a special method called Symbol.iterator, which results in empty result
being rendered.
* improved a test for iterables in {{#each}} returning empty result
* #each helper: using ES5 instead of generator functions in tests
* #each helper: using ES5 in the helper itself

  HelperMissing-functions in "helpers" and not in "container.hooks".
- Handlebars now accepts precompiled templates of version 7.
- If a precompiled template with version 7 is loaded,

Nils Knappmeier 42841c41a4 fix: disallow access to the constructor in templates to prevent RCE
This commit fixes a Remote Code Execution (RCE) reported by
npm-security. Access to non-enumerable "constructor"-properties
is now prohibited by the compiled template-code, because this
the first step on the way to creating and execution arbitrary
JavaScript code.
The vulnerability affects systems where an attacker is allowed to
inject templates into the Handlebars setup.
Further details of the attack may be disclosed by npm-security.

Nils Knappmeier 79309659e1 Gracefully handle missing uglify-js dependency
closes #1391

uglify-js is an optional dependency and should be treated as such.
This commit gracefully handles MODULE_NOT_FOUND errors while loading
uglify.

- Check for existing uglify-js (and load uglify-js) only if minification
  was activated
- Use "require.resolve" to check if uglify exists. Otherwise, a missing
  dependency of uglify-js would cause the same behavior as missing
  uglify-js. (Only a warning, no error)
- The code to load and run uglify is put into a single for readability
  purposes
- Tests use a mockup Module._resolveFilename to simulate the missing module.
  This function is used by both "require" and "require.resolve", so both
  are mocked equally.

Nils Knappmeier 5b76f041b3 Fix build on Windows
Closes #1233

- Handle path-separators properly. Use "path.sep" instead of "/".
  Or use "require.resolve()" if possible
- Use "execFile" instead of "exec" to run the Handlebars executable.
  This prevents problems due to (missing) shell escaping.
- Use explicit call to "node" in order to run the executable on Windows.
- Add "appveyor"-CI in order to run regular tests on Windows.

Nils Knappmeier 8a836e2272 Handlebars.compile() does not modify "options" anymore
Fixes #1327

- This commit creates a shallow copy of the "options" passed to
  Handlebars.compile() in order to prevent modifications
- Note that "new Handlebars.Compiler().compile(..., options)" still
  modify the options object. This might change in the future, if
  anybody needs a fix for that.

Closes #1341

{{#if @partial-block}}...{{/if}}, the partialBlockWrapper is executed
without "options"-parameter. It should still work in without an error
in such a case.

Nils Knappmeier c8f4b570c1 Fix context-stack when calling block-helpers on null values
Fixes #1319

Original behaviour:
- When a block-helper was called on a null-context, an empty object was used
  as context instead. (#1093)
- The runtime verifies that whether the current context equals the
  last context and adds the current context to the stack, if it is not.
  This is done, so that inside a block-helper, the ".." path can be used
  to go back to the parent element.
- If the helper is called on a "null" element, the context was added, even
  though it shouldn't be, because the "null != {}"

Fix:
- The commit replaces "null" by the identifiable "container.nullContext"
  instead of "{}". "nullContext" is a sealed empty object.
- An additional check in the runtime verifies that the context is
  only added to the stack, if it is not the nullContext.

Backwards compatibility within 4.0.x-versions:
- This commit changes the compiler and compiled templates would not work
  with runtime-versions 4.0.0 - 4.0.6, because of the "nullContext"
  property. That's way, the compiled code reads
  "(container.nullContext || {})" so that the behavior will degrade
  gracefully with older runtime versions: Everything else will work
  fine, but GH-1319 will still be broken, if you use a newer compiler
  with a pre 4.0.7 runtime.

Nils Knappmeier a023cb4dd9 Make "column"-property of Errors enumerable
Fixes #1284

Appearently, there is a use-case of stringifying the error in order to
evaluated its properties on another system. There was a regression
from 4.0.5  to 4.0.6 that the column-property of compilation errors
was not  enumerable anymore in 4.0.6 (due to  commit 20c965c) and
thus was not included in the output of "JSON.stringify".

Lon Ingram ef9e0dc2ab Walk up data frames for nested @partial-block
The root cause of #1218 is that `invokePartial` creates a stack of data frames
for nested partial blocks, but `resolvePartial` always uses the value at top of
the stack without "popping" it. The result is an infinite recursive loop, as
references to `@partial-block` in the partial at the top of the stack resolve to
itself.

So, walk up the stack of data frames when evaluating. This is accomplished by
1) setting the `partial-block` property to `noop` after use and
2) using `_parent['partial-block']` if `partial-block` is `noop`
