GRMustache

GRMustache is an Objective-C implementation of the Mustache logic-less template engine, for MacOS 10.6+, iPhoneOS 3.0, iOS 4.0, and iOS 5.0.

It supports the regular Mustache syntax, the Mustache specification v1.1.2, except for whitespace management (more on that below), and language extensions brought by Handlebars.js.

Full features list:

HTML-escaped variable tags: {{name}}
Unescaped variable tags: {{{name}}} and {{&name}}
Sections (boolean, enumerable, inverted, lambdas): {{#name}}...{{/name}}
partials (and recursive partials): {{>name}}
delimiter changes: {{=<% %>=}}
comments: {{!...}}
"dotted names": {{foo.bar}}
"implicit iterator": {{.}}
"extended paths" of Handlebars.js: {{../foo/bar}}

Note that:

GRMustache does not honor the whitespace management rules of the Mustache specification v1.1.2: each character of your templates will be rendered as is.
The default rendering of GRMustache is compatible with Handlebars.js. This means that support for "extended paths" such as {{../foo/bar}} is enabled by default. In order to use the "dotted names" of Mustache v1.1.2, such as {{foo.bar}}, you will have to ask for them explicitely.

Embedding in your XCode project

GRMustache ships as a static library and a header file, and only depends on the Foundation.framework.

The GRMustache.h header file is located into the /include folder at the root of the GRMustache repository. Add it to your project.

You'll have next to choose a static library among those located in the /lib folder:

libGRMustache1-ios3.a
libGRMustache1-ios4.a
libGRMustache1-macosx10.6.a

libGRMustache1-ios3.a targets iOS3+, and include both device and simulator architectures (i386 armv6 armv7). This means that this single static library allows you to run GRMustache on both simulator and iOS devices.

libGRMustache1-ios4.a targets iOS4+, and include both device and simulator architectures (i386 armv6 armv7). On top of all the APIs provided by libGRMustache1-ios3.a, you'll find blocks and NSURL* APIs in this version of the lib.

libGRMustache1-macosx10.6.a targets MaxOSX 10.6+. It includes both 32 and 64 bits architectures (i386 x86_64), and the full set of GRMustache APIs.

Versioning and backward compatibility

Until GRMustache hits version 2, there is no risk upgrading GRMustache in your project: you will get bugfixes and improvements without changing a line of your code.

You may well get deprecation warnings, but these are only warnings. Support for deprecated APIs will only be removed in the next major version.

This is because GRMustache versioning policy complies to the one defined by the Apache APR.

Advanced topics

This README file provides with basic GRMustache documentation. Check out the wiki for discussions on some more advanced topics.

Simple example

#import "GRMustache.h"

NSDictionary *object = [NSDictionary dictionaryWithObject:@"Mom" forKey:@"name"];
[GRMustacheTemplate renderObject:object fromString:@"Hi {{name}}!" error:nil];
// returns @"Hi Mom!"

Rendering methods

The main rendering methods provided by the GRMustacheTemplate class are:

// Renders the provided templateString.
+ (NSString *)renderObject:(id)object
                fromString:(NSString *)templateString
                     error:(NSError **)outError;

// Renders the template loaded from a url. (from MacOS 10.6 and iOS 4.0)
+ (NSString *)renderObject:(id)object
         fromContentsOfURL:(NSURL *)url
                     error:(NSError **)outError;

// Renders the template loaded from a path.
+ (NSString *)renderObject:(id)object
        fromContentsOfFile:(NSString *)path
                     error:(NSError **)outError;

// Renders the template loaded from a bundle resource of extension "mustache".
+ (NSString *)renderObject:(id)object
              fromResource:(NSString *)name
                    bundle:(NSBundle *)bundle
                     error:(NSError **)outError;

// Renders the template loaded from a bundle resource of provided extension.
+ (NSString *)renderObject:(id)object
              fromResource:(NSString *)name
             withExtension:(NSString *)ext
                    bundle:(NSBundle *)bundle
                     error:(NSError **)outError;

All those methods perform a rendering that is compatible with Handlebars.js and its "extended paths", such as {{../foo/bar}} (see below).

In order to process the "dotted names" of Mustache v1.1.2, such as {{foo.bar}}, you have to ask for it explicitely:

The recommended way is to call, prior to any rendering, the following method:

[GRMustache setDefaultTemplateOptions:GRMustacheTemplateOptionMustacheSpecCompatibility];
[GRMustacheTemplate renderObject:...]   // will use Mustache v1.1.2 rendering

Since GRMustache 2 will stop using Handlebars as its default behavior, think of this line as something similar to Python's from __future__ import ... (see PEP 236). When GRMustache hits version 2, it will be easier for you to migrate.

You may also take the explicit and more verbose path, and provide the GRMustacheTemplateOptionMustacheSpecCompatibility option to methods below.

enum {
    // default, with support for extended paths of Handlebars.js
    GRMustacheTemplateOptionNone = 0,
    
    // support for the dotted names of Mustache v1.1.2
    GRMustacheTemplateOptionMustacheSpecCompatibility = 0x01,
};

typedef NSUInteger GRMustacheTemplateOptions;

// Renders the provided templateString.
+ (NSString *)renderObject:(id)object
                fromString:(NSString *)templateString
                   options:(GRMustacheTemplateOptions)options
                     error:(NSError **)outError;

// Renders the template loaded from a url. (from MacOS 10.6 and iOS 4.0)
+ (NSString *)renderObject:(id)object
         fromContentsOfURL:(NSURL *)url
                   options:(GRMustacheTemplateOptions)options
                     error:(NSError **)outError;

// Renders the template loaded from a path.
+ (NSString *)renderObject:(id)object
        fromContentsOfFile:(NSString *)path
                   options:(GRMustacheTemplateOptions)options
                     error:(NSError **)outError;

// Renders the template loaded from a bundle resource of extension "mustache".
+ (NSString *)renderObject:(id)object
              fromResource:(NSString *)name
                    bundle:(NSBundle *)bundle
                   options:(GRMustacheTemplateOptions)options
                     error:(NSError **)outError;

// Renders the template loaded from a bundle resource of provided extension.
+ (NSString *)renderObject:(id)object
              fromResource:(NSString *)name
             withExtension:(NSString *)ext
                    bundle:(NSBundle *)bundle
                   options:(GRMustacheTemplateOptions)options
                     error:(NSError **)outError;

Errors

GRMustache methods may return errors whose domain is GRMustacheErrorDomain.

extern NSString* const GRMustacheErrorDomain;

Their error codes may be interpreted with the GRMustacheErrorCode enumeration:

typedef enum {
	GRMustacheErrorCodeParseError,
	GRMustacheErrorCodeTemplateNotFound,
} GRMustacheErrorCode;

Compiling templates

If you are planning to render the same template multiple times, it is more efficient to parse it once, with the compiling methods of the GRMustacheTemplate class:

// Parses the templateString.
+ (id)parseString:(NSString *)templateString
            error:(NSError **)outError;

// Loads and parses the template from url. (from MacOS 10.6 and iOS 4.0)
+ (id)parseContentsOfURL:(NSURL *)url
                   error:(NSError **)outError;

// Loads and parses the template from path.
+ (id)parseContentsOfFile:(NSString *)path
                    error:(NSError **)outError;

// Loads and parses the template from a bundle resource of extension "mustache".
+ (id)parseResource:(NSString *)name
             bundle:(NSBundle *)bundle
              error:(NSError **)outError;

// Loads and parses the template from a bundle resource of provided extension.
+ (id)parseResource:(NSString *)name
      withExtension:(NSString *)ext
             bundle:(NSBundle *)bundle
              error:(NSError **)outError;

Those methods return GRMustacheTemplate instances, which render objects with the following method:

- (NSString *)renderObject:(id)object;

For instance:

// Compile template
GRMustacheTemplate *template = [GRMustacheTemplate parseString:@"Hi {{name}}!" error:nil];
// @"Hi Mom!"
[template renderObject:[NSDictionary dictionaryWithObject:@"Mom" forKey:@"name"]];
// @"Hi Dad!"
[template renderObject:[NSDictionary dictionaryWithObject:@"Dad" forKey:@"name"]];
// @"Hi !"
[template renderObject:nil];
// @"Hi !", shortcut to renderObject:nil
[template render];

All those methods return templates that are compatible with Handlebars.js and its "extended paths", such as {{../foo/bar}} (see below).

In order to process the "dotted names" of Mustache v1.1.2, such as {{foo.bar}}, you have to ask for it explicitely. See "Rendering methods" above.

Context objects

You will provide a rendering method with a context object.

Mustache tag names are looked for in the context object, through the standard Key-Value Coding method valueForKey:.

The most obvious objects which support KVC are dictionaries. You may also provide with any other object:

@interface Person: NSObject
+ (id)personWithName:(NSString *)name;
- (NSString *)name;
@end

// returns @"Hi Mom!"
[GRMustacheTemplate renderObject:[Person personWithName:@"Mom"]
                      fromString:@"Hi {{name}}!"
                           error:nil];

A KVC key miss can raise a NSUndefinedKeyException. GRMustache catches those exceptions:

// doesn't raise, and returns @"Hi !"
[GRMustacheTemplate renderObject:[Person personWithName:@"Mom"]
                      fromString:@"Hi {{XXX}}!"
                           error:nil];

Those exceptions are part of the regular rendering of a template. Yet, when debugging your project, they may become an annoyance. Check the Avoid the NSUndefinedKeyException attack wiki page.

Tag types

We'll now cover all mustache tag types, and how they are rendered.

But let's give some definitions first:

GRMustache considers enumerable all objects conforming to the NSFastEnumeration protocol, but NSDictionary. The most obvious enumerable is NSArray.
GRMustache considers false KVC key misses, and the following values: nil, [NSNull null], [NSNumber numberWithBool:NO], kCFBooleanFalse, and the empty string @"".

The topic of booleans is not trivial. Check the Booleans wiki page.

Comments `{{!...}}`

Comments tags are not rendered.

Variable tags `{{name}}`

Such a tag is rendered according to the value for key name in the context.

If the value is false, the tag is not rendered.

Otherwise, it is rendered with the regular string description of the value, HTML escaped.

Unescaped variable tags `{{{name}}}` and `{{&name}}`

Such a tag is rendered according to the value for key name in the context.

If the value is false, the tag is not rendered.

Otherwise, it is rendered with the regular string description of the value, without HTML escaping.

Sections `{{#name}}...{{/name}}`

Sections are rendered differently, depending on the value for key name in the context:

False sections

If the value is false, the section is not rendered.

The topic of booleans is not trivial. Check the Booleans wiki page.

Enumerable sections

If the value is enumerable, the text between the {{#name}} and {{/name}} tags is rendered once for each item in the enumerable.

Each item becomes the context while being rendered. This is how you iterate over a collection of objects:

My shopping list:
{{#items}}
- {{name}}
{{/items}}

When a key is missed at the item level, it is looked for in the enclosing context.

Lambda sections

Read below "Lambdas", which covers in detail how GRMustache allows you to provide custom code for rendering sections.

Other sections

Otherwise - if the value is not enumerable, false, or lambda - the content of the section is rendered once.

The value becomes the context while being rendered. This is how you traverse an object hierarchy:

{{#me}}
  {{#mother}}
    {{#father}}
      My mother's father was named {{name}}.
    {{/father}}
  {{/mother}}
{{/me}}

When a key is missed, it is looked for in the enclosing context. This is the base mechanism for templates like:

{{! If there is a title, render it in a <h1> tag }}
{{#title}}
  <h1>{{title}}</h1>
{{/title}}

Inverted sections `{{^name}}...{{/name}}`

Such a section is rendered when the {{#name}}...{{/name}} section would not: in the case of false values, or empty enumerables.

Partials `{{>partial_name}}`

A {{>partial_name}} tag is rendered as a partial loaded from the file system.

Partials must have the same extension as their including template.

Recursive partials are possible. Just avoid infinite loops in your context objects.

Depending on the method which has been used to create the original template, partials will be looked for in different places :

In the main bundle:
- renderObject:fromString:error:
- parseString:error:
In the specified bundle:
- renderObject:fromResource:bundle:error:
- renderObject:fromResource:withExtension:bundle:error:
- parseResource:bundle:error:
- parseResource:withExtension:bundle:error:
Relatively to the URL of the including template:
- renderObject:fromContentsOfURL:error:
- parseContentsOfURL:error:
Relatively to the path of the including template:
- renderObject:fromContentsOfFile:error:
- parseContentsOfFile:error:

The "Template loaders" section below will show you more partial loading GRMustache features.

Implicit iterator, dotted names and extended paths

Implicit iterator

The dot "." stands for the current context itself. This dot key can be useful when iterating a list of scalar objects. For instance, the following context:

context = [NSDictionary dictionaryWithObject:[NSArray arrayWithObjects: @"beer", @"ham", nil]
                                      forKey:@"item"];

renders:

<ul><li>beer</li><li>ham</li></ul>

when applied to the template:

<ul>{{#item}}<li>{{.}}</li>{{/item}}</ul>

Extended paths

GRMustache supports extended paths introduced by Handlebars.js. Paths are made up of typical expressions and / characters. Expressions allow you to not only display data from the current context, but to display data from contexts that are descendents and ancestors of the current context.

To display data from descendent contexts, use the / character. So, for example, if your context were structured like:

context = [NSDictionary dictionaryWithObjectsAndKeys:
           [Person personWithName:@"Alan"], @"person",
           [Company companyWithName:@"Acme"], @"company",
           nil];

you could display the person's name from the top-level context with the following expression:

{{person/name}}

Similarly, if already traversed into the person object you could still display the company's name with an expression like ``{{../company/name}}`, so:

{{#person}}{{name}} - {{../company/name}}{{/person}}

would render:

Alan - Acme

Dotted names

GRMustache supports the dotted names of Mustache v1.1.2. Dotted names are made up of typical names and . characters. Expressions allow you to not only display data from the current context, but to display data from contexts that are descendents of the current context.

To display data from descendent contexts, use the . character. So, for example, if your context were structured like:

context = [NSDictionary dictionaryWithObjectsAndKeys:
           [Person personWithName:@"Alan"], @"person",
           nil];

you could display the person's name from the top-level context with the following expression:

{{person.name}}

You have to explicitely ask for the Mustache spec compatibility in order to use dotted names. See "Rendering methods" above.

Lambdas

Mustache lambdas allow you to execute custom code when rendering a mustache section such as:

{{#name}}...{{/name}}

GRMustache provides you with two ways in order to define your lambdas. The first one requires some selectors to be implemented, the second uses Objective-C blocks.

For the purpose of demonstration, we'll implement a lambda that translates, via NSLocalizedString, the content of the section: one will expect {{#localize}}Delete{{/localize}} to output Effacer when the locale is French.

Implementing lambdas with methods

If the context used for mustache rendering implements the localizeSection:withContext: selector (generally, a method whose name is the name of the section, to which you append Section:withContext:), then this method will be called when rendering the section.

The choice of the class that should implement this selector is up to you, as long as it can be reached when rendering the template, just as regular values.

For instance, let's focus on the following template snippet:

{{#cart}}
    {{#items}}
        {{quantity}} × {{name}}
        {{#localize}}Delete{{/localize}}
    {{/items}}
{{/cart}}

When the localize section is rendered, the context contains an item object, an items collection, a cart object, plus any surrounding objects.

If the item object implements the localizeSection:withContext: selector, then its implementation will be called. Otherwise, the selector will be looked up in the items collection. Since this collection is likely an NSArray instance, the lookup will continue with the cart and its surrounding context, until some object is found that implements the localizeSection:withContext: selector.

In order to have a reusable localize lambda, we'll isolate it in a specific class, MustacheHelper, and make sure this helper is provided to GRMustache when rendering our template.

Let's first declare our helper class:

@interface MustacheHelper: NSObject

Since our helper doesn't carry any state, let's declare our localizeSection:withContext: selector as a class method:

    + (NSString *)localizeSection:(GRMustacheSection *)section withContext:(id)context;
@end

The literal inner content

Now up to the first implementation. The section argument is a GRMustacheSection object, which represents the section being rendered: {{#localize}}Delete{{/localize}}.

This section object has a templateString property, which returns the literal inner content of the section. It will return @"Delete" in our specific example. This looks like a perfect argument for NSLocalizedString:

@implementation MustacheHelper
+ (NSString *)localizeSection:(GRMustacheSection *)section withContext:(id)context
{
    return NSLocalizedString(section.templateString, nil);
}
@end

So far, so good, this would work as expected.

Rendering the inner content

Yet the application keeps on evolving, and it appears that the item names should also be localized. The template snippet now reads:

{{#cart}}
    {{#items}}
        {{quantity}} × {{#localize}}{{name}}{{/localize}}
        {{#localize}}Delete{{/localize}}
    {{/items}}
{{/cart}}

Now the strings we have to localize may be:

literal strings from the template: {{#localize}}Delete{{/localize}}
strings coming from cart items : {{#localize}}{{name}}{{/localize}}

Our first MustacheHelper will fail, since it will return NSLocalizedString(@"{{name}}", nil) when localizing item names.

Actually we now need to feed NSLocalizedString with the rendering of the inner content, not the literal inner content.

Fortunately, we have:

the renderObject: method of GRMustacheSection, which renders the content of the receiver with the provided object.
the context parameter, which is the current rendering context, containing a cart item, an item collection, a cart, and any surrouding objects.

[section renderObject:context] is exactly what we need: the inner content rendered in the current context.

Now we can fix our implementation:

@implementation MustacheHelper
+ (NSString *)localizeSection:(GRMustacheSection *)section withContext:(id)context
{
    NSString *renderedContent = [section renderObject:context];
    return NSLocalizedString(renderedContent, nil);
}
@end

Using the helper object

Now that our helper class is well defined, let's use it.

Assuming:

orderConfirmation.mustache is a mustache template resource,
self has a cart property suitable for our template rendering,

Let's first parse the template:

GRMustacheTemplate *template = [GRMustacheTemplate parseResource:@"orderConfirmation" bundle:nil error:NULL];

Let's now render, with two objects: our MustacheHelper class that will provide the localize lambda, and self that will provide the cart:

[template renderObjects:[MustacheHelper class], self, nil];

Implementing lambdas with blocks

Starting MacOS6 and iOS4, blocks are available to the Objective-C language. GRMustache provides a block-based lambda API.

This technique does not involve declaring any special selector. But when asked for the localized key, your context will return a GRMustacheBlockHelper instance, built in the same fashion as the helper methods seen above:

id localize = [GRMustacheBlockHelper helperWithBlock:(^(GRMustacheSection *section, id context) {
    NSString *renderedContent = [section renderObject:context];
    return NSLocalizedString(renderedContent, nil);
}];

See how the block implementation is strictly identical to the lambda method discussed above.

Actually, your only concern is to make sure your values and lambda code can be reached by GRMustache when rendering your templates. Implementing localizeSection:withContext or returning a GRMustacheBlockHelper instance for the localize key is strictly equivalent.

Speaking of the localize key, we need some container object:

id mustacheHelper = [NSDictionary dictionaryWithObject:localize forKey:@"localize"];

And now the rendering is done as usual:

[template renderObjects:mustacheHelper, self, nil];

Usages of lambdas

Lambdas can be used for whatever you may find relevant.

You may implement caching:

// {{#cached}}...{{/cached}}
- (NSString *)cachedSection:(GRMustacheSection *)section withContext:(id)context {
  if (self.cache == nil) { self.cache = [section renderObject:context]; }
  return self.cache;
};

You may render an extended context:

// {{#extended}}...{{/extended}}
+ (NSString *)extendedSection:(GRMustacheSection *)section withContext:(id)context {
  return [section renderObjects:context, ...];
});

You may render a totally different context:

// {{#alternative}}...{{/alternative}}
+ (NSString *)alternativeSection:(GRMustacheSection *)section withContext:(id)context {
  return [section renderObject:[NSDictionary ...]];
});

You may implement debugging sections:

// {{#debug}}...{{/debug}}
+ (NSString *)debugSection:(GRMustacheSection *)section withContext:(id)context {
  NSLog(section.templateString);         // log the unrendered section 
  NSLog([section renderObject:context]); // log the rendered section 
  return nil;                            // don't render anything
});

Template loaders

Fine tuning loading of templates

The GRMustacheTemplateLoader class is able to load templates and their partials from anywhere.

The Implementing your own template loading strategy wiki page will tell you how to subclass GRMustacheTemplateLoader in order to load templates and partials from an NSDictionary.

The GRMustacheTemplateLoader class itself is able to load templates and their partials from anywhere in the file system, and provides more options than the high-level methods already seen.

You may instantiate one with the following GRMustacheTemplateLoader class methods:

// Loads templates and partials from a directory, with "mustache" extension, encoded in UTF8 (from MacOS 10.6 and iOS 4.0)
+ (id)templateLoaderWithBaseURL:(NSURL *)url;

// Loads templates and partials from a directory, with provided extension, encoded in UTF8 (from MacOS 10.6 and iOS 4.0)
+ (id)templateLoaderWithBaseURL:(NSURL *)url
                      extension:(NSString *)ext;

// Loads templates and partials from a directory, with provided extension, encoded in provided encoding (from MacOS 10.6 and iOS 4.0)
+ (id)templateLoaderWithBaseURL:(NSURL *)url
                      extension:(NSString *)ext
                       encoding:(NSStringEncoding)encoding;

// Loads templates and partials from a directory, with "mustache" extension, encoded in UTF8
+ (id)templateLoaderWithDirectory:(NSString *)path;

// Loads templates and partials from a directory, with provided extension, encoded in UTF8
+ (id)templateLoaderWithDirectory:(NSString *)path
                        extension:(NSString *)ext;

// Loads templates and partials from a directory, with provided extension, encoded in provided encoding
+ (id)templateLoaderWithDirectory:(NSString *)path
                        extension:(NSString *)ext
                         encoding:(NSStringEncoding)encoding;

// Loads templates and partials from a bundle, with "mustache" extension, encoded in UTF8
+ (id)templateLoaderWithBundle:(NSBundle *)bundle;

// Loads templates and partials from a bundle, with provided extension, encoded in UTF8
+ (id)templateLoaderWithBundle:(NSBundle *)bundle
                     extension:(NSString *)ext;

// Loads templates and partials from a bundle, with provided extension, encoded in provided encoding
+ (id)templateLoaderWithBundle:(NSBundle *)bundle
                     extension:(NSString *)ext
                      encoding:(NSStringEncoding)encoding;

Once you have a GRMustacheTemplateLoader object, you may load a template from its location:

GRMustacheTemplate *template = [loader parseTemplateNamed:@"document" error:nil];

You may also have the loader parse a template string. Only partials would then be loaded from the loader's location:

GRMustacheTemplate *template = [loader parseString:@"..." error:nil];

The rendering is done as usual:

NSString *rendering = [template renderObject:...];

All those template loaders return templates that are compatible with Handlebars.js and its "extended paths", such as {{../foo/bar}} (see below).

In order to process the "dotted names" of Mustache v1.1.2, such as {{foo.bar}}, you have to ask for it explicitely. See "Rendering methods" above.

A less simple example

Let's be totally mad, and display a list of people and their birthdates in a UIWebView embedded in our iOS application.

We'll most certainly have a UIViewController for displaying the web view:

@interface PersonListViewController: UIViewController
@property (nonatomic, retain) NSArray *persons;
@property (nonatomic, retain) IBOutlet UIWebView *webView;
@end

The persons array contains some instances of our Person model:

@interface Person: NSObject
@property (nonatomic, retain) NSString *name;
@property (nonatomic, retain) NSDate *birthdate;
@end

A PersonListViewController instance and its array of persons is a graph of objects that is already perfectly suitable for rendering our template:

PersonListViewController.mustache:

<html>
<body>
<dl>
  {{#persons}}
  <dt>{{name}}</dt>
  <dd>{{localizedBirthdate}}</dd>
  {{/persons}}
</dl>
</body>
</html>

We already see the match between our classes' properties, and the persons and name keys. More on the birthdate vs. localizedBirthdate later.

We should already be able to render most of our template:

@implementation PersonListViewController
- (void)viewWillAppear:(BOOL)animated {
  // Let's use self as the rendering context:
  NSString *html = [GRMustacheTemplate renderObject:self
                                       fromResource:@"PersonListViewController"
                                       bundle:nil
                                       error:nil];
  [self.webView loadHTMLString:html baseURL:nil];
}
@end

Now our {{#persons}} enumerable section and {{name}} variable tag will perfectly render.

What about the {{localizedBirthdate}} tag?

Since we don't want to pollute our nice and clean Person model, let's add a category to it:

@interface Person(GRMustache)
