* [ios, macos] Import headers, not implementation files
* [core] Added accessors for various expression parameters
Added missing parameter accessors to various expression operator classes, as well as a method on InterpolatorBase and Step that enumerates the stops and their values.
* [ios, macos] Silenced warning in test of error condition
* [ios, macos] Made MGLSphericalPosition boxable
* [ios, macos] Implemented array enumeration during conversion
* [ios, macos] Temporarily ignore heatmap layer type
* [ios, macos] Migrated MGLSymbolStyleLayer.text to NSExpression
MGLSymbolStyleLayer.text is now of type NSExpression instead of MGLStyleValue, as a first step toward migrating the entire layer API from style values to expressions.
Implemented conversions from NSExpression to JSON arrays and vice versa. The most common NSExpression functions are now converted into style expressions, but not all of the most common style expression operators are supported yet.
* [ios, macos] Implemented string coercion
* [ios, macos] Color literals
* [ios, macos] Null constant expressions
* [ios, macos] Convert dictionary literals
* [ios, macos] Interpolation expressions
* [ios, macos] to-boolean, to-number, get from object
* [ios, macos] Variable expressions
Implemented custom expression functions for assigning and referring to variables within the context of an expression. Variables are assigned via a “context dictionary” and applied to an subexpression that is given as another argument to the same expression. Also implemented built-in variable expressions for zoom level and heatmap density.
* [ios, macos] Convert colors, offsets, padding in expressions to JSON objects
* [ios, macos] Expression-based style property getters
Implemented a conversion from mbgl::style::PropertyValues to Objective-C JSON objects, which are then converted to NSExpressions.
* [ios, macos] Consolidated property value–expression conversion in MGLStyleValueTransformer
* [ios, macos] Predicate and expression guide
Extracted documentation about predicates from a documentation comment in MGLVectorStyleLayer.h to a new jazzy guide. Added details about NSExpression support as well. Began updating the “For Style Authors” guide to reflect the transition from style values to expressions.
* [ios, macos] Updated style authoring guide
Updated the Information for Style Authors guide to discuss expressions instead of style functions. Included a table mapping style specification expression operators to NSExpression syntaxes.
* [ios, macos] Migrated codegen templates to expressions
* [ios, macos] Applied expression changes via codegen
Ran make darwin-style-code.
* [macos] Migrated macosapp to expressions
* [ios, macos] Updated style function guide
This guide needs to be thoroughly rewritten, but for now the example code has been migrated to expressions.
* [ios, macos] Eviscerated style function tests
* [ios, macos] Updated changelogs
* [ios] Migrated iosapp to expressions
* [ios, macos] Exposed JSON conversion methods publicly
* [ios, macos] Removed MGLStyleValue, MGLStyleFunction
This adds two new convenience initializers to MGLShapeSource:
-initWithIdentifier:features:options: takes an array of shape objects
that conform to MGLFeature, inserts them in a shape collection feature
and creates a source with that shape. -initWithIdentifier:shapes:options
does the same but with concrete MGLShape objects that get added to
a shape collection.
Throw an exception if an shape source is created with the features
initializer but is sent an array of features that contains something
that is not actually an object that conforms to the feature protocol.
Updates to geojson data guide
Qualify APIs that take arrays of shapes that are features
* [ios, macos] Audited source headers for nullability
* [macos] Made MGLTileSet public
* [ios, macos] Replaced MGLTileSet with MGLTileSource
MGLRasterSource and MGLVectorSource now share a common abstract superclass, MGLTileSource. MGLTileSet has been removed. MGLTileSource is modeled after mbgl::style::RasterSource and mbgl::style::VectorSource. It has initializers that incorporate the parameters of MGLTileSet’s initializers, but it lacks getters for everything but the attribution string. MGLTileSet’s properties have been converted into options that can be passed into MGLTileSource’s initializers in a dictionary.
Properly implement rawSource as a covariant property so that it doesn’t end up getting autosynthesized as a shadow ivar. This prevents concrete subclasses of MGLSource from setting _rawSource directly but getting a different value out of self.rawSource.
Marked -[MGLSource init] as unavailable and ensured that concrete subclasses of MGLSource have the right set of initializers marked as designated initializers.
Documentation comments for each concrete source class identify the corresponding source type in the style specification. Clarified the purpose of MGLTileSetScheme, now known as MGLTileCoordinateSystem.
* [ios, macos] Clarified tile size interpretation
Sticking to a default value of 256 for mapbox: URLs, but other URLs get the standard 512 value.
* [ios, macos] rawSource is always set
* [ios, macos] Cleaned up MGLShapeSource initialization
rawSource is never nil, so there’s no need for a -commonInit method. Extracted -geoJSONOptions from MGLShapeSource into a standalone function for easier testing.
* [ios, macos] Synchronized headers in project
Realphabetized headers in groups. Added headers missing from one project or the other.
* [ios, macos] Added MGLShape methods to (de)serialize GeoJSON data
Added a class initializer and instance method to MGLShape that deserialize and serialize the shape as GeoJSON data, respectively. The new initializer handles parsing errors gracefully.
Removed methods specific to GeoJSON data from MGLShapeSource, in an effort to reduce parallel state. Developers are now expected to go through the new MGLShape initializer to get an MGLShape representation. Alternatively, a local file URL can be passed into the other MGLShapeSource initializer.
* [ios, macos] Typo in assertion message
* [ios, macos] Simplified GeoJSON serialization
Every MGLShape now knows its most specific mbgl::GeoJSON representation.
* [ios, macos] Reremoved MGLFeaturePrivate
mbgl::GeoJSON, which is a variant, allows a single GeoJSON representation method to traffic in whatever type is needed for a particular shape class. This change removes some hidden private protocols, which are a bug waiting to happen.
* [ios, macos] Fixed covariant rawLayer property
Properly implement rawLayer as a covariant property so that it doesn’t end up getting autosynthesized as a shadow ivar. This prevents concrete subclasses of MGLStyleLayer from setting _rawLayer directly but getting a different value out of self.rawLayer.
* [ios, macos] Use MGLAttributionInfo for source attribution
Made MGLAttributionInfo public. Replaced MGLTileSource’s attribution property with an attributionInfos property set to an array of MGLAttributionInfo objects. Added an MGLTileSourceOption for specifying an array of MGLAttributionInfo objects instead of an HTML string (either is acceptable when creating an MGLTileSource).
* [ios, macos] Corrected method references in documentation
This checks the kind of MGLShape passed into the source and, if it
is a feature, it mbgl feature objects to pass to core. This keeps the
feature id and attributes data intact. If the shape is a
`MGLShapeCollectionFeature` it creates an `mbgl::FeatureCollection`
object (also to keep feature properties). If the shape is not any
sort of feature, it passes along just the geometry.
This also uses the MGLFeatureFromMBGLFeature converter for the case where
GeoJSON data passed in to a source contains a single feature. The
converter has logic to keep the id and attributes properties intact.
Before, these properties were lost because only geometry conversion
was done.
Finally, logic to handle (and associated tests) of nested shape
collection features is removed since that is not supported by
the GeoJSON spec or the core implementation.
