* [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
* [ios, macos] Made MGLMapView.style property nullable
MGLMapView’s style property is now nullable (optional in Swift). The property is set to nil while the style loads and in the event that the style has failed to load.
* [ios, macos] Switch to delegate method
* [macos] Create MGLMapView programmatically for layer tests
When MGLMapView is created via a nib, -initWithCoder: is called, causing styleURL to be set to nil, in turn causing the default Streets style to be loaded, fooling MGLStyleLayerTests into thinking one-line has been loaded. Instead, create MGLMapView programmatically, passing the intended style URL into the initializer, preventing Streets from being loaded.
* [ios, macos] Removed extraneous code fences
* [ios] Streamlined example delimiters
Use test method names as names of example blocks and test method documentation comments as front matter for examples. Set off example blocks using a syntax similar to playground markup syntax. Avoid hard-coding indentation levels. Trigger Xcode build error when an error occurs in the script.
* [ios] Removed platform-specific code from examples
* [ios] Fixed logic error
The comment said 200 while the code said 1,500.
* [ios] Formalize build phase input
* [ios] Insert examples into original source documentation
Rewrote the example code insertion script to work on the original source files and overwrite any existing code examples on the same symbols. The script uses SourceKitten to find the documentation comment for the symbol named by the test method.
Replaced the Run Script build phase that runs the example code insertion script with a make rule that runs the same script. Inlined skeleton examples minus the contents of the code blocks.
* [ios] Fixed syntax error
* [ios] Ran ios-add-examples-to-docs
* [ios] Avoid touching unchanged headers
* [ios] Refactored example insertion script
* [ios] Point jazzy at original sources
* [ios] Invoke SourceKitten only once
* [ios] Look for methods as well as properties
* [ios] Thoroughly search for code blocks in doc comments
Refactored the example code insertion script to index test methods by their names, then recursively search the SourceKitten output for documentation comments that contain Swift code blocks, replacing each code block with the associated test method body.
* [ios, macos] Enabled example insertion for macOS
The example code insertion script is now platform-agnostic.
* [ios, macos] Fixed documentation example tests
Set the map view’s style to a minimal local JSON file. Wait for the style to finish loading before running each test. Corrected CGVector type.
* [ios, macos] Dry run mode
The output of this mode isn’t a good indicator of whether any files would’ve needed to be changed, because the presence of a conditional compilation block in one of the test methods means this script would always change and revert the corresponding comment.
* [ios] Fixed test failure
The iOS implementation of MGLMapView tries to show the Streets style by default even if no access token has been set. Avoid a race condition and frequent test failure by specifying the minimal style on initialization.
* [ios, macos] Ensure SourceKitten is installed before inserting example code
* [ios, macos] Tear down map view after each test
Keep map views from previous tests from hanging around, potentially obscuring the result of a subsequent test. Set the access token to a bogus token upfront for all style layer tests. Unified MGLStyle usage within MGLStyleTests.
* [ios, macos] Reinsert examples after generating runtime styling headers
