Tree-sitter Grammar for Mail

Neovim

In Neovim, this can be installed with lewis6991/ts-install.nvim: Treesitter parser manager for Neovim. Add to its opts:

parsers = {
  mail = {
    install_info = {
      url = 'https://github.com/stevenxxiu/tree-sitter-mail',
      branch = 'master',
    },
  },
},

To parse the body, in e.g., Markdown, add to ~/.config/nvim/after/queries/mail/injections.scm:

((body) @injection.content
 (#set! injection.language "markdown"))
