At Replit, they've made it easier to support any project configuration possible by providing intelligent code completion and documentation for all `.replit` files. They used Taplo, an LSP server for TOML files, to achieve this, generating a JSON Schema from their existing Go codebase that includes descriptions for each field. To document the `Command` type, they developed a custom schema generator function that produces a JSON Schema with descriptions for all fields, including those used in different contexts. Additionally, Replit has introduced a new Nix module called "replit" that provides LSP configuration for the `.replit` file and is loaded automatically in every Repl. This change aims to make editing the `.replit` file a more seamless experience.
