List of requirements for using kulala.

Optional Requirements

To make things a lot easier, you can put this lua snippet somewhere in your configuration:

vim.filetype.add({
  extension = {
    ['http'] = 'http',
  },
})

This will make Neovim recognize files with the .http extension as HTTP files.

Kulala.nvim comes with a parser compiled with the latest version of treesitter.

If you have Neovim 0.10.x, you might get an error ABI version mismatch for kulala_http.so: supported between 13 and 14, found 15.

You need to install tree-sitter CLI and recompile the parser:

1. Delete the existing parser at nvim-treesitter/parser/kulala_http
2. Install the tree-sitter CLI (if not installed already):
   • from distribution repositories
   • or from https://github.com/tree-sitter/tree-sitter/tree/master/crates/cli
3. Recompile the parser:
   • Open a http file in Neovim (this will load Kulala)
   • Run :TSInstallFromGrammar kulala_http
