Asynchronous rsync with Emacs, dired and tramp.
|
||
|
|
======
|
||
|
|
|
||
|
|
[tmtxt-dired-async][1] by [Trần Xuân Trường][2] is an unfortunately lesser known Emacs package which extends dired, the Emacs file manager, to be able to run rsync and other commands (zip, unzip, downloading) asynchronously.
|
||
|
|
|
||
|
|
This means you can copy gigabytes of directories around whilst still happily continuing with all of your other tasks in the Emacs operating system.
|
||
|
|
|
||
|
|
It has a feature where you can add any number of files from different locations into a wait list with `C-c C-a`, and then asynchronously rsync the whole wait list into a final destination directory with `C-c C-v`. This alone is worth the price of admission.
|
||
|
|
|
||
|
|
For example here it is pointlessly rsyncing the arduino 1.9 beta archive to another directory:

|
||
|
|
|
||
|
|
When the process is complete, the window at the bottom will automatically be killed after 5 seconds. Here is a separate session right after the asynchronous unzipping of the above-mentioned arduino archive:

|
|
||
|
|
This package has further increased the utility of my dired configuration.
|
||
|
|
|
||
|
|
I just contributed [a pull request that enables tmtxt-dired-async to rsync to remote tramp-based directories][7], and I immediately used this new functionality to sort a few gigabytes of new photos onto the Linux server.
|
||
|
|
|
||
|
|
To add tmtxt-dired-async to your config, download [tmtxt-async-tasks.el][8] (a required library) and [tmtxt-dired-async.el][9] (check that my PR is in there if you plan to use this with tramp) into your `~/.emacs.d/` and add the following to your config:
|
||
|
|
|
||
|
|
```
|
||
|
|
;; no MELPA packages of this, so we have to do a simple check here
|
||
|
|
(setq dired-async-el (expand-file-name "~/.emacs.d/tmtxt-dired-async.el"))
|
||
|
|
(when (file-exists-p dired-async-el)
|
||
|
|
(load (expand-file-name "~/.emacs.d/tmtxt-async-tasks.el"))
|
||
|
|
(load dired-async-el)
|
||
|
|
(define-key dired-mode-map (kbd "C-c C-r") 'tda/rsync)
|
||
|
|
(define-key dired-mode-map (kbd "C-c C-z") 'tda/zip)
|
||
|
|
(define-key dired-mode-map (kbd "C-c C-u") 'tda/unzip)
|
||
|
|
|
||
|
|
(define-key dired-mode-map (kbd "C-c C-a") 'tda/rsync-multiple-mark-file)
|
||
|
|
(define-key dired-mode-map (kbd "C-c C-e") 'tda/rsync-multiple-empty-list)
|
||
|
|
(define-key dired-mode-map (kbd "C-c C-d") 'tda/rsync-multiple-remove-item)
|
||
|
|
(define-key dired-mode-map (kbd "C-c C-v") 'tda/rsync-multiple)
|
||
|
|
|
||
|
|
(define-key dired-mode-map (kbd "C-c C-s") 'tda/get-files-size)
|
||
|
|
|
||
|
|
(define-key dired-mode-map (kbd "C-c C-q") 'tda/download-to-current-dir))
|
||
|
|
```
|
||
|
|
|

|
|
Enjoy!
