* [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
Mapbox GL Native
A library for embedding interactive, customizable vector maps into native applications on multiple platforms. It takes stylesheets that conform to the Mapbox Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using OpenGL. Mapbox GL JS is the WebGL-based counterpart, designed for use on the Web.
The Mapbox GL ecosystem
This repository hosts the cross-platform Mapbox GL Native library, plus convenient SDKs for several platforms. The cross-platform library comes with a GLFW-based demo application for Ubuntu Linux and macOS. The SDKs target the usual languages on their respective platforms:
| SDK | Languages | Build status |
|---|---|---|
| Mapbox GL Native | C++14 |   |
| Mapbox Maps SDK for Android | Java | |
| Mapbox Maps SDK for iOS | Objective-C or Swift |  |
| Mapbox Maps SDK for macOS | Objective-C, Swift, or AppleScript |  |
| node-mapbox-gl-native | Node.js | |
| Mapbox Qt SDK | C++03 | |
Additional Mapbox GL Native–based libraries for hybrid applications are developed outside of this repository:
| Toolkit | Android | iOS | Developer |
|---|---|---|---|
| React Native (npm) | ✅ | ✅ | Mapbox |
| Apache Cordova (npm) | ✅ | ✅ | Telerik |
| NativeScript (npm) | ✅ | ✅ | Telerik |
| Xamarin | ✅ | ✅ | Xamarin |
If your platform or hybrid application framework isn’t listed here, consider embedding Mapbox GL JS using the standard Web capabilities on your platform.
