;;; bookmark.el --- Saved files and directories on my filesystem -*- lexical-binding: t -*-
|
|
;; Author: William Carroll <wpcarro@gmail.com>
|
|
|
|
;;; Commentary:
|
|
;; After enjoying and relying on Emacs's builtin `jump-to-register' command, I'd
|
|
;; like to recreate this functionality with a few extensions.
|
|
;;
|
|
;; Everything herein will mimmick my previous KBDs for `jump-to-register', which
|
|
;; were <leader>-j-<register-kbd>. If the `bookmark-path' is a file, Emacs will
|
|
;; open a buffer with that file. If the `bookmark-path' is a directory, Emacs
|
|
;; will open an ivy window searching that directory.
|
|
|
|
;;; Code:
|
|
|
|
(require 'f)
|
|
(require 'buffer)
|
|
(require 'list)
|
|
(require 'string)
