# See http://editorconfig.org to read about the EditorConfig format.
# - In theory automatically supported by VS2017+ and most common IDE or text editors.
# - In practice VS2019-VS2022 stills don't trim trailing whitespaces correctly :(
# - Suggest installing this to trim whitespaces:
# GitHub https://github.com/madskristensen/TrailingWhitespace
# VS2019 https://marketplace.visualstudio.com/items?itemName=MadsKristensen.TrailingWhitespaceVisualizer
# VS2022 https://marketplace.visualstudio.com/items?itemName=MadsKristensen.TrailingWhitespace64
# (in spite of its name doesn't only visualize but also trims)
# - Alternative for older VS2010 to VS2015: https://marketplace.visualstudio.com/items?itemName=EditorConfigTeam.EditorConfig
# top-most EditorConfig file
root = true
