** How to use YARA Language Server?

Install the official YARA-X Language Server (yr-ls) from [[https://github.com/VirusTotal/yara-x][VirusTotal/yara-x]]: #+begin_src bash cargo install yara-x-ls #+end_src

*** Eglot (Emacs 29+)

yara-mode automatically registers yr-ls with eglot. Simply call M-x eglot or add to your init.el: #+begin_src elisp (add-hook 'yara-mode-hook #'eglot-ensure) #+end_src

*** lsp-mode

To use lsp-mode, add the following to your init.el: #+begin_src elisp (with-eval-after-load 'lsp-mode (add-to-list 'lsp-language-id-configuration '(yara-mode . "yara"))

(lsp-register-client (make-lsp-client :new-connection (lsp-stdio-connection '("yr-ls")) :activation-fn (lsp-activate-on-modes 'yara-mode) :server-id 'yara-x-ls)))

(add-hook 'yara-mode-hook #'lsp-deferred) #+end_src
