GL style spec, validation, and migration scripts for mapbox-gl-js and mapbox-gl-native.

Install

npm install -g mapbox-gl-style-spec

Provides the utilities:

• gl-style-migrate
• gl-style-format
• gl-style-validate
• gl-style-spritify

Validation

$ gl-style-validate style.json

Will validate the given style JSON and print errors to stdout. Provide a --json flag to get JSON output.

Migrations

This repo contains scripts for migrating GL styles of any version to the latest version (currently v8). Migrate a style like this:

$ gl-style-migrate bright-v7.json > bright-v8.json

To migrate a file in place, you can use the sponge utility from the moreutils package:

$ brew install moreutils
$ gl-style-migrate bright.json | sponge bright.json

Building Sprites

The gl-style-spritify command can build sprite files for use in GL styles. Generate an image sprite by running this script on one or more directories of images.

The first parameter is the basename that gl-style-spritify will use to generate .json, .png, @2x.json and @2x.png files. For example, if you pass bright, bright.json, bright.png, etc will be generated in the currrent directory.

Subsequent parameters are paths to directories which hold images to be included in the sprite.

$ gl-style-spritify bright sprite-assets
