### Install Tree-sitter Grammars with Combobulate

Source: https://github.com/mickeynp/combobulate/blob/master/README.rst

This Elisp code defines a function to install specified tree-sitter grammars if they are absent. It includes a list of grammars with their respective GitHub repository URLs and versions, ensuring compatibility with Combobulate and Emacs.

```elisp
(use-package treesit
  :mode (("\.tsx\'" . tsx-ts-mode))
  :preface
  (defun mp-setup-install-grammars ()
    "Install Tree-sitter grammars if they are absent."
    (interactive)
    (dolist (grammar
             ;; Note the version numbers. These are the versions that
             ;; are known to work with Combobulate *and* Emacs.
             '((css . ("https://github.com/tree-sitter/tree-sitter-css" "v0.20.0"))
               (go . ("https://github.com/tree-sitter/tree-sitter-go" "v0.20.0"))
               (html . ("https://github.com/tree-sitter/tree-sitter-html" "v0.20.1"))
               (javascript . ("https://github.com/tree-sitter/tree-sitter-javascript" "v0.20.1" "src"))
               (json . ("https://github.com/tree-sitter/tree-sitter-json" "v0.20.2"))
               (markdown . ("https://github.com/ikatyang/tree-sitter-markdown" "v0.7.1"))
               (python . ("https://github.com/tree-sitter/tree-sitter-python" "v0.20.4"))
               (rust . ("https://github.com/tree-sitter/tree-sitter-rust" "v0.21.2"))
               (toml . ("https://github.com/tree-sitter/tree-sitter-toml" "v0.5.1"))
               (tsx . ("https://github.com/tree-sitter/tree-sitter-typescript" "v0.20.3" "tsx/src"))
               (typescript . ("https://github.com/tree-sitter/tree-sitter-typescript" "v0.20.3" "typescript/src"))
               (yaml . ("https://github.com/ikatyang/tree-sitter-yaml" "v0.5.0"))
               (ocaml . ("https://github.com/tree-sitter/tree-sitter-ocaml" "v0.24.2" "grammars/ocaml/src"))
               ))
      (treesit-install-grammar (car grammar) (cadr grammar) (caddr grammar))))))

### Load Custom Elisp File

Source: https://github.com/mickeynp/combobulate/blob/master/README.rst

This is an example of how to load a custom Elisp file, such as the tuareg-treesit bridge, into your Emacs configuration.

```elisp
(load "path-to-tuareg-treesit.el")
```

### Install and Configure Combobulate

Source: https://github.com/mickeynp/combobulate/blob/master/README.rst

This snippet shows a basic Emacs Lisp configuration for Combobulate. It includes setting a custom key prefix and enabling Combobulate mode for programming modes. Ensure you update the `:load-path` to your local checkout of Combobulate.

```elisp
(use-package combobulate
   :custom
   ;; You can customize Combobulate's key prefix here.
   ;; Note that you may have to restart Emacs for this to take effect!
   (combobulate-key-prefix "C-c o")
   :hook ((prog-mode . combobulate-mode))
   ;; Amend this to the directory where you keep Combobulate's source
   ;; code.
   :load-path ("path-to-git-checkout-of-combobulate"))
```

### Configure Tuareg Mode with Tree-sitter Bridge

Source: https://github.com/mickeynp/combobulate/blob/master/README.rst

This Elisp code configures Emacs to use the tree-sitter parser for OCaml within the tuareg-mode. It ensures the parser is created when needed and assumes OCaml grammars are already installed.

```elisp
(require 'tuareg)
(require 'treesit)

(defun tuareg-treesit-bridge-create-parser ()
  "Create a Tree-sitter parser in the current Tuareg buffer if absent.
   Assumes the OCaml Tree-sitter grammars are already installed by the user."
  (when (and (derived-mode-p 'tuareg-mode)
             (fboundp 'treesit-available-p) 
             (treesit-available-p)
             (treesit-language-available-p 'ocaml))
    (unless (treesit-parser-list)
      (treesit-parser-create
       (if (and buffer-file-name (string-match-p "\.mli\'" buffer-file-name))
           'ocaml-interface
         'ocaml)))))

(add-hook 'tuareg-mode-hook #'tuareg-treesit-bridge-create-parser)

(provide 'tuareg-treesit)
;;; tuareg-treesit.el ends here
```
