Functions to maintain a simple personal diary / journal using in Emacs.
Feel free to use, modify and improve the code! — mtvoid, bastibe
org-journal maintains a set of files, depending on the value of
  org-journal-file-type, a file represents a day, week, month or year. When
  org-journal-file-type is set to 'daily, each file represent a day. In case
  org-journal-file-type is set to 'weekly, a file represents a week,
  etc. Convenient bindings allow the creation of journal records in the current
  daily, weekly, monthly or yearly file and search within all records or
  specified time intervals. All records can be browsed and searched from the
  Emacs Calendar for convenience. All entries in a specified TODO state will be
  carried over to the next day, see org-journal-carryover-items. Optionally,
  the journal entry can be encrypted, so can the file, see
  org-journal-enable-encryption and org-journal-encrypt-journal,
  respectively.
Every journal entry must have a CREATED property when using yearly, monthly
  and weekly journal files. This property is added by org-journal-new-entry
  automatically.
An example of a daily file (it will actually look a lot nicer, depending on your org-mode settings):
* Tuesday, 06/04/13 ** 10:28 Company meeting Endless discussions about projects. Not much progress ** 11:33 Work on org-journal For the longest time, I wanted to have a cool diary app on my computer. However, I simply lacked the right tool for that job. After many hours of searching, I finally found PersonalDiary on EmacsWiki. PersonalDiary is a very simple diary system based on the emacs calendar. It works pretty well, but I don't really like that it only uses unstructured text. Thus, I spent the last two hours making that diary use org-mode and represent every entry as an org-mode headline. Very cool! ** 15:33 Work on org-journal Now my journal automatically creates the right headlines (adds the current time stamp if on the current day, does not add a time stamp for any other day). Additionally, it automatically collapses the headlines in the org-file to the right level (shows everything if in view mode, shows only headlines in new-entry-mode). Emacs and elisp are really cool! ** 16:40 Work on org-journal I uploaded my journal mode to marmalade and Github! Awesome! ** TODO teach org-journal how to brew coffee
An example of a weekly/monthly/yearly journal file, see also
  org-journal-file-type.
* Tuesday, 06/04/13 :PROPERTIES: :CREATED: 20130604 :END: ** 10:28 Company meeting ... ** 11:33 Work on org-journal ... ** 15:33 Work on org-journal ... ** 16:40 Work on org-journal ... * Wednesday, 06/05/13 :PROPERTIES: :CREATED: 20130605 :END: ** 10:28 A new day ... ** 11:33 Work is almost over ... ** TODO teach org-journal how to brew coffee
org-journal is available through NonGNU ELPA, MELPA and MELPA Stable. So
  installation should be trivial:
M-x package-install org-journal
Then add (require 'org-journal) to your .emacs.
Note! If you are using org-mode version 9.6 consider customizing the variable org-element-use-cache and setting it to nil to workaround an issue where journal items are not properly carried over to the next day
Doing M-x org-journal-new-entry will immediately create a journal
  directory in the default path (customized using the org-journal-dir
  variable), open or create a file in org-journal-mode, and insert a
  template for a new journal entry.
The same command with a prefix argument (C-u M-x
  org-journal-new-entry) will do everything mentioned while skipping
  entry creation, which is useful for looking at the current journal
  file.
Bindings available in org-journal-mode:
- C-c C-f- go to the next journal file.
- C-c C-b- go to the previous journal file.
- C-c C-j- insert a new entry into the current journal file (creates the file if not present).
- C-c C-s- search the journal for a string.
All journal entries are registered in the Emacs Calendar. To see available journal
  entries do M-x calendar. Bindings available in the calendar-mode:
- j m- mark entries in calendar
- j r- view an entry in a new buffer.
- j d- view an entry but do not switch to it.
- j n- add a new entry into the day’s file (creates the file if not present).
- j s w- search in all entries of the current week.
- j s m- search in all entries of the current month.
- j s y- search in all entries of the current year.
- j s f- search in all entries of all time.
- j s F- search in all entries in the future.
- [- go to previous day with journal entries.
- ]- go to next day with journal entries.
The following variables can be customized through M-x customize, or configured programmatically in your .init.el.
See below for an example.
Customization options related to journal directory and files:
- org-journal-dir- the journal path.
- org-journal-file-format- format string for journal file names (may contain directories relative to- org-journal-dir).
- org-journal-find-file- a function to use when opening a journal file. By default it opens a window using- find-file-other-window. Set this to- find-fileif you don’t want org-journal to split your window.
- org-extend-today-until- a number that indicates the hour of your end of the day. If you create a new entry with- org-journal-new-entryearlier than this time, the journal entry will go into the previous day’s journal.
- org-journal-file-type- the journal file type either ‘daily (default), ‘weekly, ‘monthly or ‘yearly. Also see the customizable variables- org-journal-start-on-weekdayfor changing the start of the week for weekly journals (defaults to Monday). Keep in mind changing- org-journal-start-on-weekdaywon’t work for existing weekly journal files.
Customization options related to the journal file contents:
- org-journal-date-format- date format- org-journaluses when showing a date within a journal and search results page. It can also be a function, which return value will than be inserted.
- org-journal-date-prefix- this string will prefix the date at the top of a journal file.
- org-journal-time-format- a timestamp format that will prefix every entry within a daily journal file.
- org-journal-time-prefix- a string that will prefix every entry within a daily journal file.
- org-journal-file-header- a string that will be inserted at the top of every new journal file. If a string, it will be passed to `format-time-string` along the time value of the new journal entry. It can also be a function expecting a time value.- (defun org-journal-file-header-func (time) "Custom function to create journal header." (concat (pcase org-journal-file-type (`daily "#+TITLE: Daily Journal\n#+STARTUP: showeverything") (`weekly "#+TITLE: Weekly Journal\n#+STARTUP: folded") (`monthly "#+TITLE: Monthly Journal\n#+STARTUP: folded") (`yearly "#+TITLE: Yearly Journal\n#+STARTUP: folded")))) (setq org-journal-file-header 'org-journal-file-header-func)
- org-journal-hide-entries-p- a boolean (defaults to- true) that will hide previous journal entries if true. Can be set to- nilto show previous entries.
Customization options related to org-journal itself:
- org-journal-mode-hook- List of functions to run when- org-journal-modeis loaded. By default this is set to- '(turn-on-visual-line-mode org-journal-default-enable-encryption).
A very basic example of customization.
(setq org-journal-dir "~/org/journal/") (setq org-journal-date-format "%A, %d %B %Y") (require 'org-journal)
For users of use-package, this setup could look like the following:
(use-package org-journal
  :ensure t
  :defer t
  :init
  ;; Change default prefix key; needs to be set before loading org-journal
  (setq org-journal-prefix-key "C-c j ")
  :config
  (setq org-journal-dir "~/org/journal/"
        org-journal-date-format "%A, %d %B %Y"))
org-journal has two searching options: the usual org-mode agenda search and the
  built-in plain text search. The former can become slow with bigger journals, so the
  built-in search is a recommended option.
To use the agenda search, you can add all journal entries to your org-agenda by adding
  org-journal-dir to org-agenda-files and setting org-agenda-file-regexp to include
  files matching your org-journal-file-pattern.
;; When =org-journal-file-pattern= has the default value, this would be the regex.
(setq org-agenda-file-regexp "\\`\\\([^.].*\\.org\\\|[0-9]\\\{8\\\}\\\(\\.gpg\\\)?\\\)\\'")
(add-to-list 'org-agenda-files org-journal-dir)
However, this can become very slow if you have many journal entries. As a compromize,
  you can set org-journal-enable-agenda-integration to t, which automatically adds the
  current and all future journal entries to the agenda. This is enough to get an overview
  over current and future tasks.
The built-in search is available through the following function: org-journal-search
  (C-c C-s in org-journal-mode). By default, it will ask for the time interval to search
  within (accepting the org-read-date format such as “-1y” or “-1m”) and the string to
  search for. Given a prefix argument (C-u org-journal-search), it will go through the
  whole journal.
The order of the search results (ascending or descending by date) can be customized using
  the org-journal-search-results-order-by variable.
Search is also available through the Emacs Calendar as described in “Basic Usage”.
By default, org-journal will try to carry over previous day TODO-marked
  items whenever a new journal file is created. The older journal entry will be inserted to the current day’s file.
This feature is controlled through the org-journal-carryover-items
  variable. To disable this feature set org-journal-carryover-items to an
  empty string "". Any agenda tags view match string, tags, properties, and
  todo states are allowed. By default this is TODO=”TODO”. Which will
  match TODO items.
The old carryover items in the previous day’s journal are processed by the function assigned to org-journal-handle-old-carryover variable.
  Default is to remove all of them. You can change this behavior by
  assigning a custom fuction to the variable.
  Your function has to take one argument, which is a list of old carryover entries. The list is in form of ((START_POINT (END_POINT . “TEXT”)) … (START_POINT (END_POINT . “TEXT”))); and in ascending order of START_POINT.
For example, you can choose putting a tag on the old carryover entries intead of removing them:
(defun my-old-carryover (old_carryover)
  (save-excursion
    (let ((matcher (cdr (org-make-tags-matcher org-journal-carryover-items))))
      (dolist (entry (reverse old_carryover))
        (save-restriction
          (narrow-to-region (car entry) (cadr entry))
          (goto-char (point-min))
          (org-scan-tags '(lambda ()
                            (org-set-tags ":carried:"))
                         matcher org--matcher-tags-todo-only))))))
(setq org-journal-handle-old-carryover 'my-old-carryover)You can also skip carry over of Drawers through the
  org-journal-skip-carryover-drawers variable. This is specifically
  useful when you want to skip carry over of previous days clocked
  entries when it is under the drawer LOGBOOK. The variable accepts a
  list of drawers names which will be skipped on carry over. Sample
  configuration for skipping LOGBOOK drawer:
(setq org-journal-skip-carryover-drawers (list "LOGBOOK"))The journal entry can be encrypted using org-crypt, to enable it set
  org-journal-enable-encryption to t.
You can also encrypt the journal files itself by setting the variable
  org-journal-encrypt-journal to t. org-journal will always search for
  journal files with the .gpg extension, and highlights them in the calendar,
  etc., regardless of the value of org-journal-encrypt-journal.
  See the info page (info "(epa)Encrypting/decrypting gpg files") for more
  information about gpg encryption in Emacs.
An easy way of keeping track of appointments or future TODOs is to simply create a journal entry in the future. Such entries will automatically get a timestamp and show up in the current day’s journal entry once you reach that day.
- if org-journal-enable-agenda-integrationist, org-journal will automatically add the current and all future journal entries toorg-agenda-files.
There are a few helper functions to deal with such scheduled entries:
- org-journal-new-scheduled-entry- prompts for a date, and creates a new journal entry on that date with its timestamp set to the date. By default, this is a TODO entry. Set the prefix to avoid the TODO.
- org-journal-schedule-view- creates a read-only overview of scheduled entries.
You can export your scheduled entries to an iCalendar file, and subscribe to that file in your calendar application. You need to enable the agenda integration for this to work. I also recommend you set the following values before exporting:
(setq org-journal-enable-agenda-integration t
      org-icalendar-store-UID t
      org-icalendar-include-todo "all"
      org-icalendar-combined-agenda-file "~/path/to/org-journal.ics")With this done, you can export your agenda, including your scheduled entries, with (org-icalendar-combine-agenda-files).
You can configure a capture template in order to integrate org-journal with org-capture,
  as in the following example for a daily journal:
(defun org-journal-find-location ()
  ;; Open today's journal, but specify a non-nil prefix argument in order to
  ;; inhibit inserting the heading; org-capture will insert the heading.
  (org-journal-new-entry t)
  (unless (eq org-journal-file-type 'daily)
    (org-narrow-to-subtree))
  (goto-char (point-max)))
(setq org-capture-templates '(("j" "Journal entry" plain (function org-journal-find-location)
                               "** %(format-time-string org-journal-time-format)%^{Title}\n%i%?"
                               :jump-to-captured t :immediate-finish t)))
If you want to do the same to schedule a task for a future date, you can use the following:
(defvar org-journal--date-location-scheduled-time nil)
(defun org-journal-date-location (&optional scheduled-time)
  (let ((scheduled-time (or scheduled-time (org-read-date nil nil nil "Date:"))))
    (setq org-journal--date-location-scheduled-time scheduled-time)
    (org-journal-new-entry t (org-time-string-to-time scheduled-time))
    (unless (eq org-journal-file-type 'daily)
      (org-narrow-to-subtree))
    (goto-char (point-max))))
(setq org-capture-templates '(("j" "Journal entry" plain (function org-journal-date-location)
                               "** TODO %?\n <%(princ org-journal--date-location-scheduled-time)>\n"
                               :jump-to-captured t))
Since version 2.0.0 a cache has been added to speed up calendar
  operations. This should drastically improve the performance when using
  encrypted journal files, see org-journal-encrypt-journal.
The caching functionality can be enabled by settings
  org-journal-enable-cache to t. The cache can be reset by calling
  org-journal-invalidate-cache.
Yes, see org-journal-file-type.
At the moment, this is not possible. But it should be possible to switch the
  value of org-journal-directory using a custom function or directory local
  variables.
Yes you can!
- To use org-journalwith Spacemacs from themasterbranch, you must do this:- git clone https://github.com/borgnix/spacemacs-journal.git ~/.emacs.d/private/journal
- add it to your ~/.spacemacs. You will need to addjournalto the existingdotspacemacs-configuration-layerslist in this file.
 The manual of the journal layer can be found at https://github.com/borgnix/spacemacs-journal 
- If you use Spacemacs from the developbranch you can enableorg-journalby settingorg-enable-org-journal-supporttot, see Spacemacs org-journal support.
Minor modes are supposed to only use key bindings of the form C-c C-?, where ? can be any letter, and to not overwrite major mode bindings. With org-mode already using most interesting keys, collisions are inevitable. This means that some org-journal key bindings will not work as expected in an org-mode buffer, and also that some org-mode key bindings will not work as expected in an org-journal buffer.
When working in an org-mode buffer the following org-journal key bindings are overwritten:
- C-c C-s(- org-journal-search) with- org-schedule
- C-c C-f(- org-journal-open-next-entry) with- org-forward-heading-same-level
- C-c C-b(- org-journal-open-previous-entry) with- org-backward-heading-same-level
- C-c C-j(- org-journal-new-entry) with- org-goto
To workaround this, you can use user bindings of the form C-c ?, where ? can be any letter, to call the org-journal functions. This allows you to have a set of keybindings that work the same in org-mode and org-journal buffers. However, this is Emacs, and if you don’t like a key binding, change it!
Old entries are opened in view-mode, which has convenient key bindings for browsing files. Most notably, you can quickly close view-mode buffers with q, scroll them with the SPC and DEL, or quit view-mode with e.
Yes, you can write a custom function and assign it org-journal-date-format.
Yes, there are two hooks that are run when a journal entry is created.
  Each (org-journal-new-entry) will call org-journal-after-entry-create-hook, and org-journal-after-header-create-hook is called each time the date (the parent headline of each entry) is generated.
