This package provides visible, buffer local, bookmarks and the ability to jump forward and backward to the next bookmark.
It was created because I missed the bookmarks from M$ Visual Studio in GNU Emacs. I think they provide an easy way to navigate in a buffer.
- Auto remove bookmark after jump to it by
bm-nextorbm-previous: - Cycle through bookmarks in all open buffers in LIFO order
- Toggle bookmarks. Jump to next/previous bookmark.
- Setting bookmarks based on a regexp. (Useful when searching logfiles.)
- Mouse navigation.
- Annotate bookmarks.
- Different wrapping modes.
- Different bookmarks styles, line-only, fringe-only or both.
- Persistent bookmarks (buffer local), also in non-file buffers (info) and indirect buffers.
- List bookmarks (in all buffers) in a separate buffer.
- Cycle through bookmarks in all open buffers.
To use bm.el, put it in your load-path and add the following to your .emacs
(require 'bm)
or
(autoload 'bm-toggle "bm" "Toggle bookmark in current buffer." t)
(autoload 'bm-next "bm" "Goto bookmark." t)
(autoload 'bm-previous "bm" "Goto previous bookmark." t)
To make it easier to use, assign the commands to some keys.
M$ Visual Studio key setup.
(global-set-key (kbd "<C-f2>") 'bm-toggle)
(global-set-key (kbd "<f2>") 'bm-next)
(global-set-key (kbd "<S-f2>") 'bm-previous)
Click on fringe to toggle bookmarks, and use mouse wheel to move between them.
(global-set-key (kbd "<left-fringe> <mouse-5>") 'bm-next-mouse)
(global-set-key (kbd "<left-fringe> <mouse-4>") 'bm-previous-mouse)
(global-set-key (kbd "<left-fringe> <mouse-1>") 'bm-toggle-mouse)
If you would like the markers on the right fringe instead of the left, add the following line:
(setq bm-marker 'bm-marker-right)
If you would like to cycle bookmark in LIFO order, add the following line:
(setq bm-in-lifo-order t)
If you would like to cycle through bookmarks in all open buffers, add the following line:
(setq bm-cycle-all-buffers t)
If you would like to remove bookmark after jump to it by bm-next or bm-previous:
(setq temporary-bookmark-p t)
or if you want use this feature in your library:
(bm-bookmark-add nil nil t)
Configuring bm.el with use-package
(use-package bm
:ensure t
:demand t
:init
;; restore on load (even before you require bm)
(setq bm-restore-repository-on-load t)
:config
;; Allow cross-buffer 'next'
(setq bm-cycle-all-buffers t)
;; where to store persistant files
(setq bm-repository-file "~/.emacs.d/bm-repository")
;; save bookmarks
(setq-default bm-buffer-persistence t)
;; Loading the repository from file when on start up.
(add-hook' after-init-hook 'bm-repository-load)
;; Restoring bookmarks when on file find.
(add-hook 'find-file-hooks 'bm-buffer-restore)
;; Saving bookmarks
(add-hook 'kill-buffer-hook #'bm-buffer-save)
;; Saving the repository to file when on exit.
;; kill-buffer-hook is not called when Emacs is killed, so we
;; must save all bookmarks first.
(add-hook 'kill-emacs-hook #'(lambda nil
(bm-buffer-save-all)
(bm-repository-save)))
;; The `after-save-hook' is not necessary to use to achieve persistence,
;; but it makes the bookmark data in repository more in sync with the file
;; state.
(add-hook 'after-save-hook #'bm-buffer-save)
;; Restoring bookmarks
(add-hook 'find-file-hooks #'bm-buffer-restore)
(add-hook 'after-revert-hook #'bm-buffer-restore)
;; The `after-revert-hook' is not necessary to use to achieve persistence,
;; but it makes the bookmark data in repository more in sync with the file
;; state. This hook might cause trouble when using packages
;; that automatically reverts the buffer (like vc after a check-in).
;; This can easily be avoided if the package provides a hook that is
;; called before the buffer is reverted (like `vc-before-checkin-hook').
;; Then new bookmarks can be saved before the buffer is reverted.
;; Make sure bookmarks is saved before check-in (and revert-buffer)
(add-hook 'vc-before-checkin-hook #'bm-buffer-save)
