chimay / torus Goto Github PK

I am using torus (elpa torus-20190308.1757) with the use-package (more or less) from the README.md
I added :demand, since :bind implies :defer.

This is message shows up upon loading.

I have the following in my emacs.el:

(use-package torus
  :ensure t
  :bind (:map torus-map
	 ("M-p" . torus-previous-location)
	 ("M-n" . torus-next-location))
  :config
  (setq torus-prefix-key "s-,")
  ;; Range 0 -> 3
  (setq torus-optional-bindings 3)
  ;; Created if non existent
  (setq torus-dirname "~/emacs/.emacs.d/torus/")
  (setq torus-load-on-startup t)
  (setq torus-save-on-exit t)
  (setq torus-autoread-file "~/emacs/.emacs.d/torus/last.el")
  (setq torus-autowrite-file torus-autoread-file)
  (setq torus-history-maximum-elements 30)
  (setq torus-maximum-horizontal-split 3)
  (setq torus-maximum-vertical-split 3)
  (torus-init)
  (torus-install-default-bindings))

Torus is installed on the system; however, upon restart I still need to either (find-library torus) and eval-buffer or I need a (require `torus) preceding my use-package line. For every other library in my file (~100 of them) use-package does the trick on its own. Why do I still need require to get torus loaded?

Upon closing emacs (i did not work with it or create a torus), it is not possible to close emacs because of this error:

If you need more information, please tell me. :)

It would be awesome of torus could automatically track changes to the mark ring and global mark ring. That one, one could the torus API to easily move between locations that one has visited :)

Is there some easy way to achieve this? I'm a total emacs noob, and I'm frustrated with how annoying it is to move between locations.

If I need to restart my emacs (e.g. when it freezes), I always come back with no torus, circles, or locations. This seems like a major problem, unless I misunderstand the intended use case of Torus.

Hi,
sorry, it's me again.. ;)

Could you please verify the use-package example from the README.
Afaik, the code in :init is executed before the package is loaded, so to me torus-init does not make sense there.
In my setup, i put torus-init in the :config part, since this is executed after the package is loaded.

Another idea for updating the use-package example (i use different user-emacs-dirs for package testing):

(torus-dirname (concat user-emacs-directory (file-name-as-directory "torus")))
(torus-autoread-file (concat torus-dirname "last.el"))

Cheers!

how to avoid this prompt on every restart of emacs? have the default configuration as in Readme.

update torus-previous-history to torus-history-older
and torus-next-history to torus-history-newer

(global-set-key (kbd "<S-prior>") 'torus-previous-history)
(global-set-key (kbd "<S-next>") 'torus-next-history)

(define-key torus-map (kbd "<next>") 'torus-history-older)
(define-key torus-map (kbd "<prior>") 'torus-history-newer)

When I try to add a second location in the same file with torus-add-location, I see an error like:

Location myNewTestament.org at line 8976 col 0 already exists in circle scriptures

Repeated for any line I move to (the line number updates in the error). The location is not added.

Since there also doesn't seem to be a ready way to update existing locations, this is a real problem.

I'm loving torus so far, but I tend to create two separate circles:

• source files for my project, and
• test files for my project.

Then, I want to quickly cycle between the first and the second circle within two separate windows or frames. (Typically, these are actually under tmux, with the second frame created by emacsclient -c.)

However, I find that when I switch circles, the other frame switches circles as well. I.e. it seems like the active circle is a global-variable. Is there any way to instead make this state per-frame?
