;;
;; Fast, character-based search library in Rust
;;
;; Inspired by flx for Emacs, uses the same basic algorithm.
;;

;;; Code:

(require 'cl-lib)
(require 'subr-x)

(defconst flxy--bin-dir
  (concat (file-name-directory load-file-name) "bin/")
  "Pre-built binaries directory path.")

(defconst flxy--dyn-name "flxy_core"
  "Dynamic module name.")

;;
;; (@* "Externals" )
;;

(declare-function flxy-core-score "flxy-core")

;;
;; (@* "Aliases" )
;;

(defalias 'flxy-score #'flxy-core-score)

;;
;; (@* "Bootstrap" )
;;

;;;###autoload
(defun flxy-load-dyn ()
  "Load dynamic module."
  (interactive)
  (unless (featurep 'flxy-core)
    (let* ((dyn-name (cl-case system-type
                       ((windows-nt ms-dos cygwin) (concat flxy--dyn-name ".dll"))
                       (`darwin (concat "lib" flxy--dyn-name ".dylib"))
                       (t (concat "lib" flxy--dyn-name ".so"))))
           (dyn-path (concat flxy--bin-dir dyn-name)))
      (module-load dyn-path)
      (message "[INFO] Successfully load dynamic module, `%s`" dyn-name))))
