more detail about `keywords` parameter

Assuming you want to retrieve icons as xcassets-ready files, and icons have defined under Icons / *** already. Then, you need to add icons or Icons (if caseSensitive) to keywords within dtc.config.json . So you can retrieve all icons under that.

*) Spaces in between will be eliminated on generating assets. Then / is treated as a folder on generation.

style

prop name	type	description
color.isEnabled	boolean	set true if you want to extract and generate color xcassets.

Templates

All templates use namespace . You can modify templates as you like once you get your own templates folder created automatically after first command execution. You can specify your own template folder by .env file.

*) If something wrong, deleting OUTPUT_PATH/extracted folder would fix the issue ( OUTPUT_PATH is defined in .env ).
