#+title: Treemacs
#+filetags: emacs-load

#+BEGIN_QUOTE
Treemacs is a file and project explorer similar to NeoTree or vim’s NerdTree, but largely inspired by the Project Explorer in Eclipse. It shows the file system outlines of your projects in a simple tree layout allowing quick navigation and exploration, while also possessing basic file management utilities.
#+END_QUOTE

Treemacs is really cool.

#+BEGIN_SRC emacs-lisp
  (use-package treemacs
    :straight t
    :after (doom-themes)
    :config
#+END_SRC

Read input from a minibuffer not a child frame.

#+BEGIN_SRC emacs-lisp
  (setq treemacs-read-string-input 'from-minibuffer)
#+END_SRC

Load the ~doom-colors~ theme, it looks nicer.

#+BEGIN_SRC emacs-lisp
  (setq doom-themes-treemacs-theme "doom-colors")
  (doom-themes-treemacs-config)
  (treemacs-load-theme 'doom-colors)
#+END_SRC

#+BEGIN_SRC emacs-lisp :exports none
  )
#+END_SRC

* Evil
Treemacs is nice, but [[id:9e101583-0fa5-4df8-beed-7741803bfe5a][evil]] Treemacs is even nicer! Enable Evil compatibility and my custom koy compatibility.

#+BEGIN_SRC emacs-lisp
  (use-package treemacs-evil
    :after (treemacs evil)
    :straight t
    :init
#+END_SRC

We first have to define a new minor mode, ~magic_rb-koy-treemacs-mode~, then hook it onto the existing ~treemacs-mode~

#+BEGIN_SRC emacs-lisp
  (define-minor-mode magic_rb-koy-treemacs-mode
    "Enable koy compatibility for Treemacs."
    :lighter " koy"
    :keymap (make-sparse-keymap)
    (evil-normalize-keymaps))
 (add-hook 'treemacs-mode-hook 'magic_rb-koy-treemacs-mode)
#+END_SRC

Then we actually populate the keymap using [[id:1c6981a5-4371-4657-b4ea-435497a80010][general.el]].

#+BEGIN_SRC emacs-lisp
  :after (general)
  :general
  (:states 'treemacs
           :predicate 'magic_rb-koy-compat-p
           :keymaps 'magic_rb-koy-treemacs-mode-map
           "t" 'ignore
           "r" 'treemacs-previous-line
           "n" 'treemacs-next-line
           "l" 'ignore))
#+END_SRC

* LSP
Integration between Treemacs and [[id:cc668372-8d95-461b-a7c6-3e2b51de3f40][LSP]]. Needs some work still.

#+BEGIN_SRC emacs-lisp
  (use-package lsp-treemacs
    :straight t
    :after (lsp-mode treemacs)
    :config
    (lsp-treemacs-sync-mode 1))
#+END_SRC
