GRMustache Release Notes

You can compare the performances of GRMustache versions at https://github.com/groue/GRMustacheBenchmark.

v5.0.0

Performance improvements, and fix for flaws in the GRMustacheDelegate API.

Besides the removal of already deprecated methods, the changes introduced in this version are very unlikely to introduce incompatibilities in your code:

  • Dropped support for iOS3.
  • Before v5.0.0, template delegates could know that the value Arthur was provided by the key name when the tag {{name}} is rendered. Delegates are now only provided with the value.
  • Before v5.0.0, a tag containing a filter expression like {{uppercase(name)}} would have a template delegate invoked with the raw Arthur value, not the filter result: ARTHUR. In v5.0.0, delegate callbacks are given always given the value GRMustache is about to render.

Removed APIs:

@interface GRMustacheInvocation : NSObject
// Removed without deprecation warning
@property (nonatomic, readonly) NSString *key;
@end

@interface GRMustacheSection: NSObject
// Deprecated in v4.3.0
@property (nonatomic, retain, readonly) id renderingContext;
@end

@interface GRMustacheTemplate: NSObject
// Deprecated in v4.3.0
- (NSString *)renderObjects:(id)object, ...;
@end

// Removed without deprecation warning
GRMustacheInterpretationFilterArgument // was part of the GRMustacheInterpretation enum.

@protocol GRMustacheTemplateDelegate<NSObject>
// Deprecated in v4.1.0
- (void)template:(GRMustacheTemplate *)template willRenderReturnValueOfInvocation:(GRMustacheInvocation *)invocation;
- (void)template:(GRMustacheTemplate *)template didRenderReturnValueOfInvocation:(GRMustacheInvocation *)invocation;
@end

v4.3.4

Restored compatibility with iOS3 and OSX6 (thanks @Bertrand).

v4.3.3

Fix a memory leak.

v4.3.2

Bugfix: Avoid the default valueForKey: implementation of Fundation collection classes like NSArray, NSSet and NSOrderedSet, which would return another collection. Fixes issue #21.

v4.3.1

Bugfix: this release restores the delegate callbacks while rendering alternate template strings in helpers.

v4.3.0

Filters

Filters allow you to process values before they are rendered, and supersede "section delegates" as the preferred way to filter values. The number formatting and array indexes.md sample codes have been updated accordingly.

New APIs:

@interface GRMustacheSection: NSObject
- (NSString *)renderTemplateString:(NSString *)string error:(NSError **)outError;
@end

@interface GRMustacheTemplate: NSObject
+ (NSString *)renderObject:(id)object withFilters:(id)filters fromString:(NSString *)templateString error:(NSError **)outError;
+ (NSString *)renderObject:(id)object withFilters:(id)filters fromContentsOfFile:(NSString *)path error:(NSError **)outError;
+ (NSString *)renderObject:(id)object withFilters:(id)filters fromContentsOfURL:(NSURL *)url error:(NSError **)outError;
+ (NSString *)renderObject:(id)object withFilters:(id)filters fromResource:(NSString *)name bundle:(NSBundle *)bundle error:(NSError **)outError;
+ (NSString *)renderObject:(id)object withFilters:(id)filters fromResource:(NSString *)name withExtension:(NSString *)ext bundle:(NSBundle *)bundle error:(NSError **)outError;
- (NSString *)renderObject:(id)object withFilters:(id)filters;
- (NSString *)renderObjectsInArray:(NSArray *)objects;
- (NSString *)renderObjectsInArray:(NSArray *)objects withFilters:(id)filters;
@end

Deprecated APIs:

@interface GRMustacheSection: NSObject
// Use renderTemplateString:error: instead.
@property (nonatomic, retain, readonly) id renderingContext;
@end

@interface GRMustacheTemplate: NSObject
// Use renderObjectsInArray: instead.
- (NSString *)renderObjects:(id)object, ...;
@end

v4.2.0

Section delegates

When an object that is attached to a Mustache section conforms to the GRMustacheDelegate protocol, it can observe and alter the rendering of the inner content of the section, just like the template's delegate.

This provides you with a better way to encapsulate behaviors that, with previous versions of GRMustache, would bloat the one and only delegate of a template.

Section delegates are used in the number formatting sample code, where the NSNumberFormatter class is given the opportunity to render formatted numbers.

v4.1.1

Total inline documentation

Headers contain documentation for every exposed API.

An online reference, automatically generated from inline documentation by appledoc can be read at http://groue.github.com/GRMustache/Reference/.

v4.1.0

GRMustacheDelegate protocol

A template's delegate is now able to know how a value will be interpreted by GRMustache.

New APIs:

typedef enum {
    GRMustacheInterpretationSection,
    GRMustacheInterpretationVariable,
} GRMustacheInterpretation;

@protocol GRMustacheTemplateDelegate<NSObject>
- (void)template:(GRMustacheTemplate *)template willInterpretReturnValueOfInvocation:(GRMustacheInvocation *)invocation as:(GRMustacheInterpretation)interpretation;
- (void)template:(GRMustacheTemplate *)template didInterpretReturnValueOfInvocation:(GRMustacheInvocation *)invocation as:(GRMustacheInterpretation)interpretation;
@end

Deprecated APIs:

@protocol GRMustacheTemplateDelegate<NSObject>
- (void)template:(GRMustacheTemplate *)template willRenderReturnValueOfInvocation:(GRMustacheInvocation *)invocation;
- (void)template:(GRMustacheTemplate *)template didRenderReturnValueOfInvocation:(GRMustacheInvocation *)invocation;
@end

GRMustacheDelegate is documented in Guides/delegate.md.

GRMustacheTemplateRepositoryDataSource protocol

The return type of -[GRMustacheTemplateRepositoryDataSource templateRepository:templateIDForName:relativeToTemplateID:] as changed from id to id<NSCopying>.

GRMustacheTemplateRepositoryDataSource is documented in Guides/template_repositories.md.

Errors

GRMustache used to output badly formatted errors. They are now easier to read.

v4.0.0

Zero numbers are false

GRMustache now considers all NSNumber instances whose boolValue is NO as false, when considering whether a section should render or not.

Previously, GRMustache used to consider only [NSNumber numberWithBool:NO] as false.

This change lets you extend the mustache language with proxy objects (objects that implement language extensions, and forward other keys to some other object) in GRMustache rendering.

See Guides/sample_code/indexes.md for a discussion on proxy objects.

Total NSUndefinedException swallowing

Whenever GRMustache performs some key lookup and valueForKey: raises a NSUndefinedException, GRMustache swallows it and keep on looking for the key up the context stack.

Previously, GRMustache used to swallow only exceptions that explicitely came from the inquired object, and for the inquired key.

This change lets you extend the mustache language with proxy objects (objects that implement language extensions, and forward other keys to some other object) in GRMustache rendering.

See Guides/sample_code/indexes.md for a discussion on proxy objects.

Support for .name keys

Keys prefixed by a dot prevent GRMustache to look up the context stack.

Beware this feature is not in the mustache specification. If your goal is to design templates that remain compatible with other Mustache implementations, don't use this syntax.

See issue #19 and https://github.com/mustache/spec/issues/10.

v3.0.1

Restored intended architectures: armv6+armv7+i386 for libGRMustache3-iOS, i386+x86_64 for libGRMustache3-MacOS.

v3.0.0

There is no option

Removed APIs:

enum {
    GRMustacheTemplateOptionNone,
    GRMustacheTemplateOptionStrictBoolean

v2.0.0

API simplification

New APIs

enum {
    // New option for processing `BOOL` and `char` properties as numbers
    GRMustacheTemplateOptionStrictBoolean = 1
}

@protocol GRMustacheHelper<NSObject>
@required
// New required method
- (NSString *)renderSection:(GRMustacheSection *)section;
@end

@end

Removed APIs and behaviors

enum {
    // GRMustache is now compliant by default to the Mustache specification:
    GRMustacheTemplateOptionMustacheSpecCompatibility = 1
}

// NSErrors with GRMustacheErrorDomain now store the line number in localizedDescription.
extern NSString* const GRMustacheErrorLine;

@interface GRMustache: NSObject

@end

@interface GRMustacheSection: NSObject
// Replaced by the innerTemplateString property
@property (nonatomic, readonly) NSString *templateString;
// See the new render method
- (NSString *)renderObject:(id)object;
- (NSString *)renderObjects:(id)object, ...;
@end

GRMustache1 used to parse and interpret Handlebars tags such as {{../foo/bar}}. GRMustache2 does no longer parse those tags.

GRMustache1 used to parse and interpret this identifier is tags such as {{this.foo}}. GRMustache2 does no longer parse the this identifier.

GRMustache1 used to look for implementations of the localizeSection:inContext: selector when rendering a {{#localize}}...{{/localize}} section. GRMustache2 relies on the GRMustacheHelper protocol only when rendering Mustache lambda sections.
