# This is a light-background theme especically for the Helix editor.
#
# The most important part here is the syntax stuff, but the theme includes UI stuff specifically for Helix, as well.
#
# What I care about is:
#   * Readable syntax, no matter the language
#   * The error messages provided by the LSP
#   * Anything special needed to make the UI non-surprising
#   * Building a minimal definition
#
# I started from a couple important sources:
#   * The [priorities and ideas](https://tonsky.me/blog/syntax-highlighting/) behind the Alabaster Theme (which exists for many editors) by Nikita Prokopov
#   * His [actual repo implementing the theme](https://github.com/tonsky/sublime-scheme-alabaster)
#   * A [theme template](https://github.com/joegm/helix-theme-template) on GitHub provided by joegm

# I don't consider this to be done! I absolutely want feedback. I absolutely will continue to tinker.
