Application architecture

External assets

A number of assets used in the app come from other repositories, and should be periodically updated. Because updating these items can be a lengthy process it is performed manually rather than at build time:

• iD presets database (https://github.com/openstreetmap/id-tagging-schema)
• iD presets icons (https://github.com/ideditor/temaki, https://github.com/mapbox/maki)
• Name Suggestion Index (https://github.com/osmlab/name-suggestion-index)
• NSI brand imagery (pulled from Facebook/Twitter/Wikipedia)
• StreetComplete quest filters (https://github.com/streetcomplete/StreetComplete)
• Weblate translations (https://hosted.weblate.org/projects/go-map/app)

Updating external assets

cd src
(cd presets && ./update.sh)			# fetches latest presets.json, etc. files and NSI
(cd presets && ./getBrandIcons.py)		# downloads images from various websites and converts them to PNG as necessary
(cd presets && ./uploadBrandIcons.sh)	# uploads imagery to gomaposm.com where they can be downloaded on demand at runtime (password required)
(cd POI-Icons && ./update.sh)			# fetches Maki/Temaki icons 
(cd xliff && ./update.sh)				# downloads latest translations from Weblate (API token required). The output is very noisy and can be ignored

Formatting

In order to have a consistent code style, please make sure to install SwiftFormat and run it on a regular basis. Consider setting up a pre-commit Git hook, as described here.

Assets

The Go Map!! app icon was created by @Binnette.

Presets and translation

Go Map!! is using iD presets, so you can improve translations by improving translations of iD presets.
