Re: Capture with (moving) attachment?

[Mikhail Skorzhinskii <mskorzhinskiy@eml.cc>]

Hi Tim,

I tried to solve the similar problem and come up with the solution with external script to do this. This is basically only tested in Linux with KDEv5 environment, but could be extended to any other DE or to work solely in emacs.

Anyway, the idea of the solution is to provide an interface to the graphical file manager, so you can select files and just "send them" to org-mode. For this I wrote elisp function that do the attaching on files you provided, then a script that pass arguments to this function via emacslcient and then a module for file manager for menu to appear.

1. Elsip function for the attaching:

(defun org-user/move-to-file-storage (files)
  "Move FILES at my file system to annex/org file storage."
    (save-excursion
      (let ((org-capture-templates org-file-capture-templates)) ;; << don't use org-file-capture-template if you don't want separate capture templates variable for this
        (org-capture))
      ;; Create as many new headings as it need to be created
      (when (> (length files) 1)
        (save-excursion
          (org-clone-subtree-with-time-shift (- (length files) 1) '(4))))
      ;; Edit these headings and attach files to them
      (dolist (file files)
        (when (file-exists-p file)
          ;; Just some sane name should be enough
          (org-edit-headline (concat "File: " (file-name-nondirectory file)))
          ;; Attach file to the storage room
          (org-attach-attach file nil 'mv)
          ;; Edit headline once again with the stored file
          (let* ((attach-dir (org-attach-dir))
                 (files (org-attach-file-list attach-dir))
                 (file (pop files)))
            (org-edit-headline
             (format "[[attachment:%s][%s]]" file (org-get-heading t t t t))))
          ;; Go to the next free heading
          (org-next-visible-heading 1)))
      ;; Make sure that we didn't cancel capture with file that was already moved
      (org-capture-finalize)
      ;; Go to the file if we want to say something about it
      (org-capture-goto-last-stored)
      ;; Save buffer just in case
      (save-buffer)))

Function implementation is very far from ideal, but it is working to some extent. There is a bug with this function: it inserts one empty headline. Should be easy to fix, sorry about that.

2. Define your capture templates

Just like the normal capture templates.

(setq org-file-capture-templates ... )

Now calling this function externally will attach files you provided, save org buffers immediately after and leave the frame open on last attached item. Every attached file will have separate heading. And every heading will be a link to the attached file.

3. Store this script somewhere in your $PATH

#!/bin/bash

# Author: Mikhail Skorzhinskii <mskorzhinskiy@eml.cc>
#
# Description: Attach file to the org-mode file storage

files=

for file in "$@"; do
    files="${files} \"${file}\""
done;

emacsclient -a "" -c -F '((name . "doom-capture"))' \
    -e "(org-user/move-to-file-storage (list ${files}))"

If you save it as "org-attach-files.sh" then you can call it like 

  org-attach-files.sh file1 file2 file3

But make sure to pass absolute paths, as emacs executable will probably operating in different directory. I personally don't care as file manager always call it with full paths. But easy to fix with readlink -e call. (i.e. file=`readlink -e ${file}` before putting it to ${files}.

4. Place this module to .local/share/kservices5/ServiceMenus/emacs.desktop

End name can be anything of course.

[Desktop Entry]
Type=Service
ServiceTypes=KonqPopupMenu/Plugin
MimeType=all/all;
Actions=org-attach-mv;
X-KDE-Priority=TopLevel

[Desktop Action org-attach-mv]
Name=Send to git-annex
Exec=emacs-org-attach-file %U
Icon=cloud-download

This should work in KDE files managers (like Dolphin). Right-click the file and you will have "Send to git annex" menu item.
