semhl.nvim

This is a re-implementation of semantic-highlight.vim in lua targeting neovim, using tree-sitter instead of the hardcoded list. And most important of all randomly generated colors with much bigger color space, never will symbols collide with the same colors.

Every identifier is a different color, an idea popularized by Evan Brooks' blog post.

setup

With Lazy, currently setup function only accept list of file types to enable plugin for.

{
  'hantianjz/semhl.nvim',
  opts    = {
    filetypes = { "c", "cpp", "h", "python", "lua", "typescript", "java" },
    max_file_size = 100 * 1024
  }
}

TODO

• Support custom tree-sitter query
• Clean up the way plugin is loaded and unloaded
• Allow changing highlight priority
• High color generation configurable
• Generate colors based on background colors
• Check for color collision with highlight next that is close in edit distance
