Added tests for indented inline sections.
Added tests for Windows-style newlines.
2011-03-04: v1.1.0
Implicit iterators.
A single period (`.`) may now be used as a name in Interpolation tags,
which represents the top of stack (cast as a String).
Dotted names.
Names containing one or more periods should be resolved as chained
properties; naïvely, this is like nesting section tags, but with some
built-in scoping protections.
2011-03-02: v1.0.1
Clarifying a point in the README about version compliance.
Adding high-level documentation to each spec file.
2011-02-28: v1.0.0
Initial Release
The repository at https://github.com/mustache/spec is the formal standard for
Mustache. It defines both normal usage and edge-case behavior for libraries
parsing the Mustache templating language (or a superset thereof).
The specification is developed as a series of YAML files, under the `specs`
directory.
Versioning
----------
This specification is being [semantically versioned](http://semver.org).
Roughly described, major version changes will always represent backwards
incompatible changes, minor version changes will always represent new language
features and will be backwards compatible, and patch ('tiny') version changes
will always be bug fixes. For the purposes of semantic versioning, the public
API is the contents of the `specs` directory and the algorithm for testing
against it.
Mustache implementations SHOULD report the most recent version of the spec
(major and minor version numbers). If an implementation has support for any
optional modules, they SHOULD indicate so with a remark attached to the
version number (e.g. "vX.Y, including lambdas" or "v.X.Y+λ"). It is
RECOMMENDED that implementations not supporting at least v1.0.0 of this spec
refer to themselves as "Mustache-like", or "Mustache-inspired".
Alternate Formats
-----------------
Since YAML is a reasonably complex format that not every language has good
tools for working with, we also provide JSON versions of the specs on a
best-effort basis.
These should be identical to the YAML specifications, but if you find the need
to regenerate them, they can be trivially rebuilt by invoking `rake build`.
It is also worth noting that some specifications (notably, the lambda module)
rely on YAML "tags" to denote special types of data (e.g. source code). Since
JSON offers no way to denote this, a special key ("`__tag__`") is injected
with the name of the tag as its value. See `TESTING.md` for more information
about handling tagged data.
Optional Modules
----------------
Specification files beginning with a tilde (`~`) describe optional modules.
At present, the only module being described as optional is regarding support
for lambdas. As a guideline, a module may be a candidate for optionality
when:
* It does not affect the core syntax of the language.
* It does not significantly affect the output of rendered templates.
* It concerns implementation language features or data types that are not
common to or core in every targeted language.
* The lack of support by an implementation does not diminish the usage of
Mustache in the target language.
As an example, the lambda module is primarily concerned with the handling of a
particular data type (code). This is a type of data that may be difficult to
support in some languages, and users of those languages will not see the lack
as an 'inconsistency' between implementations.
Support for specific pragmas or syntax extensions, however, are best managed
outside this core specification, as adjunct specifications.
Implementors are strongly encouraged to support any and all modules they are
reasonably capable of supporting.
require 'json'
require 'yaml'
# Our custom YAML tags must retain their magic.
%w[ code ].each do |tag|
YAML::add_builtin_type(tag) { |_,val| val.merge(:__tag__ => tag) }
end
desc 'Build all alternate versions of the specs.'
multitask :build => [ 'build:json' ]
namespace :build do
note = 'Do not edit this file; changes belong in the appropriate YAML file.'
desc 'Build JSON versions of the specs.'
task :json do
rm(Dir['specs/*.json'], :verbose => false)
Dir.glob('specs/*.yml').each do |filename|
json_file = filename.gsub('.yml', '.json')
File.open(json_file, 'w') do |file|
doc = YAML.load_file(filename)
file << doc.merge(:__ATTN__ => note).to_json()
end
end
end
end
Testing your Mustache implementation against this specification should be
relatively simple. If you have a readily available testing framework on your
platform, your task may be even simpler.
In general, the process for each `.yml` file is as follows:
1. Use a YAML parser to load the file.
2. For each test in the 'tests' array:
1. Ensure that each element of the 'partials' hash (if it exists) is
stored in a place where the interpreter will look for it.
2. If your implementation will not support lambdas, feel free to skip over
the optional '~lambdas.yml' file.
2.1. If your implementation will support lambdas, ensure that each member of
'data' tagged with '!code' is properly processed into a language-
specific lambda reference.
* e.g. Given this YAML data hash:
`{ x: !code { ruby: 'proc { "x" }', perl: 'sub { "x" }' } }`
a Ruby-based Mustache implementation would process it such that it
was equivalent to this Ruby hash:
`{ 'x' => proc { "x" } }`
* If your implementation language does not currently have lambda
examples in the spec, feel free to implement them and send a pull
request.
* The JSON version of the spec represents these tagged values as a hash
with a '`__tag__`' key of 'code'.
3. Render the template (stored in the 'template' key) with the given 'data'
hash.
4. Compare the results of your rendering against the 'expected' value; any
differences should be reported, along with any useful debugging
information.
* Of note, the 'desc' key contains a rough one-line description of the
behavior being tested -- this is most useful in conjunction with the
file name and test 'name'.

overview: |
Interpolation tags are used to integrate dynamic content into the template.
The tag's content MUST be a non-whitespace character sequence NOT containing
the current closing delimiter.
This tag's content names the data to replace the tag. A single period (`.`)
indicates that the item currently sitting atop the context stack should be
used; otherwise, name resolution is as follows:
1) Split the name on periods; the first part is the name to resolve, any
remaining parts should be retained.
2) Walk the context stack from top to bottom, finding the first context
that is a) a hash containing the name as a key OR b) an object responding
to a method with the given name.
3) If the context is a hash, the data is the value associated with the
name.
4) If the context is an object, the data is the value returned by the
method with the given name.

overview: |
Inverted Section tags and End Section tags are used in combination to wrap a
section of the template.
These tags' content MUST be a non-whitespace character sequence NOT
containing the current closing delimiter; each Inverted Section tag MUST be
followed by an End Section tag with the same content within the same
section.
This tag's content names the data to replace the tag. Name resolution is as
follows:
1) Split the name on periods; the first part is the name to resolve, any
remaining parts should be retained.
2) Walk the context stack from top to bottom, finding the first context
that is a) a hash containing the name as a key OR b) an object responding
to a method with the given name.
3) If the context is a hash, the data is the value associated with the
name.
4) If the context is an object and the method with the given name has an
arity of 1, the method SHOULD be called with a String containing the
unprocessed contents of the sections; the data is the value returned.
5) Otherwise, the data is the value returned by calling the method with
the given name.
6) If any name parts were retained in step 1, each should be resolved
against a context stack containing only the result from the former
resolution. If any part fails resolution, the result should be considered
falsey, and should interpolate as the empty string.
If the data is not of a list type, it is coerced into a list as follows: if
the data is truthy (e.g. `!!data == true`), use a single-element list
containing the data, otherwise use an empty list.
This section MUST NOT be rendered unless the data list is empty.
Inverted Section and End Section tags SHOULD be treated as standalone when
appropriate.

Partial tags are used to expand an external template into the current
template.
The tag's content MUST be a non-whitespace character sequence NOT containing
the current closing delimiter.
This tag's content names the partial to inject. Set Delimiter tags MUST NOT
affect the parsing of a partial. The partial MUST be rendered against the
context stack local to the tag. If the named partial cannot be found, the
empty string SHOULD be used instead, as in interpolations.
Partial tags SHOULD be treated as standalone when appropriate. If this tag
is used standalone, any whitespace preceding the tag should treated as
indentation, and prepended to each line of the partial before rendering.

overview: |
Section tags and End Section tags are used in combination to wrap a section
of the template for iteration
These tags' content MUST be a non-whitespace character sequence NOT
containing the current closing delimiter; each Section tag MUST be followed
by an End Section tag with the same content within the same section.
This tag's content names the data to replace the tag. Name resolution is as
follows:
1) Split the name on periods; the first part is the name to resolve, any
remaining parts should be retained.
2) Walk the context stack from top to bottom, finding the first context
that is a) a hash containing the name as a key OR b) an object responding
to a method with the given name.
3) If the context is a hash, the data is the value associated with the
name.
4) If the context is an object and the method with the given name has an
arity of 1, the method SHOULD be called with a String containing the
unprocessed contents of the sections; the data is the value returned.
5) Otherwise, the data is the value returned by calling the method with
the given name.
6) If any name parts were retained in step 1, each should be resolved
against a context stack containing only the result from the former
resolution. If any part fails resolution, the result should be considered
falsey, and should interpolate as the empty string.
If the data is not of a list type, it is coerced into a list as follows: if
the data is truthy (e.g. `!!data == true`), use a single-element list
containing the data, otherwise use an empty list.
For each element in the data list, the element MUST be pushed onto the
context stack, the section MUST be rendered, and the element MUST be popped
off the context stack.
Section and End Section tags SHOULD be treated as standalone when
appropriate.

overview: |
Lambdas are a special-cased data type for use in interpolations and
sections.
When used as the data value for an Interpolation tag, the lambda MUST be
treatable as an arity 0 function, and invoked as such. The returned value
MUST be rendered against the default delimiters, then interpolated in place
of the lambda.
When used as the data value for a Section tag, the lambda MUST be treatable
as an arity 1 function, and invoked as such (passing a String containing the
unprocessed section contents). The returned value MUST be rendered against
the current delimiters, then interpolated in place of the section.
