A package to make sense of
my life org-journal records.
The package adds the
org-journal: link type to Org Mode. When placed in an org-journal file, the link serves as a “tag” that references one or many paragraphs of the journal or the entire section. These tags are aggregated in the database that can be queried in various ways.
Journal files, by their very nature, are weakly structured. A single journal note can reference multiple entities (or none) and can itself be composed of multiple parts that have in common only the date and time when they were written. Needless to say, it’s hard to find anything in such records.
This package attempts to improve the accessibility of the journal by:
- Taking advantage of temporal data, e.g. allowing to query entries in some date range.
- Allowing to extract (and reference) only certain parts of a particular journal entry.
- Compensating weak structure by with more advanced query engine.
For instance, when I’m writing down the progress on a job project, I can leave a tag like
job.<project-name> in the paragraph(s) related to that project. Later, I can query only those paragraphs that are referenced by this particular tag. The query results can then be narrowed, for instance, to include the word “backend”, or extended with some other tag.
If no tag matches the subject matter, the journal can be queried with a regular expression, e.g. by searching some regex within a specific time frame. Subsequent searches are also significantly faster than the built-in
org-journal search functionality due to the to caching mechanism.
The package is available on MELPA. Install it however you normally install packages, my preferred way is
To add an inline tag, you can manually create a link of the following format:
M-x org-journal-tags-insert-tag to insert a tag with a completion interface. The description is not aggregated and thus optional. Also,
<tag-name> cannot contain
The link will reference the current Org Mode paragraph. If you want to reference more paragraphs, you can set the number of paragraphs like this:
M-x org-journal-tags-link-get-region-at-point to select the referenced region of the buffer.
To add a tag to the entire section, run
M-x org-journal-tags-prop-set, which will create or update the
Tags property in the property drawer of the current time section. This command features a notmuch-like UI, i.e. completing read for multiple entries, where
+<tag> adds a tag and
-<tag> deletes a tag.
If you decide to rename a tag, there’s
Tag kind is a predefined class of tag with some extra functionality. The link format fo such tags is as follows:
<kind> is omitted, a tag is considered “normal”.
C-u M-x org-journal-tags-insert-tag will first prompt for the tag kind and then for the tag itself from the set of already used tags of that kind.
C-u C-u M-x org-journal-tags-insert-tag will also first prompt for the tag kind, but then will try to invoke the kind-specific tag selection logic, if such is available. For instance, the
contact kind will prompt the
For now, the only available tag kind is org-contacts.
In addition to tags, the package also aggregates inline timestamps, i.e. timestamps that are left in the text like this:
This is a text. This is a text with <2022-04-07 Thu> a timestamp. This is a text again.
A timestamp will reference just the current paragraph.
Other forms of timestamps (
DEADLINE, etc.) are not supported at the moment, because this functionality is implemented well enough by org-agenda.
The envisioned use case for this functionality to leave references for the future to be seen at a particular date.
The package stores tags and references to these tags in a database.
org-journal-tags-autosync-mode enables synchronizing the database at the moment of saving of the org-journal buffer. You can also run the synchronization manually:
M-x org-journal-tags-process-bufferto process the current buffer.
M-x org-journal-tags-db-syncto sync changed org-journal files in the filesystem.
The same mode enables saving the database on killing Emacs, but you can always run
M-x org-journal-tags-db-save manually.
M-x org-journal-tags-db-unload saves and unloads the database from the memory,
M-x org-journal-tags-db-reset creates a new database.
(I replaced tag names with “X” just for the screenshot)
M-x org-journal-tags-status opens the status buffer with some statistics about the journal and tags. Press
? to see the available keybindings.
RET on a tag name in the “All tags” section should open a query buffer set to return all references for this tag.
s in the status buffer or running
M-x org-journal-tags-transient-query opens a transient.el buffer with query settings.
The options are as follows:
- Include tags filters the references so that each reference had at least one of these tags.
- Exclude tags filters the references so that each reference didn’t have any of these tags.
- Include children includes child tags to the previous two lists.
- Tag location can filter only section tags on inline tags.
- Start date and End date filter the references by date.
- Filter timestamps filters the references so that they include a timestamp.
- Timestamp start date and Timestamp end date filter timestamps by their date.
- Regex filter the references by a regular expression. It can be a string or rx expression (it just has to start with
(rxin this case).
- Narrow to regex makes it so that each reference had only paragraphs that have a regex match.
- Sort sorts the result in ascending order. It’s descending by default.
e executes the query. Journal files are cached, so subsequent queries within one session are much faster.
After the query completes, the package opens the results buffer. Press
? to see the available keybindings there.
RET opens the corresponding org-journal entry.
s opens the query constructor buffer. If opened from inside the query results, the query constructor has 4 additional options:
|old ∪ new
|Add records of the new query to the displayed records
|old ∩ new
|Leave only those records that are both displayed and in the new query
|Difference from current
|old \ new
|Exclude records of the new query from the displayed records
|Difference to current
|new \ old
|Exclude displayed records from ones of the new query
Thus it is possible to make any query that can be described as a sequence of such set operations.
org-journal provides a hook to automatically add information to the journal entries.
It can be used to automatically assign tags, for instance, based on hostname. Here’s an excerpt from my configuration:
(defun my/set-journal-header ()
(org-journal-tags-prop-apply-delta :add (list (format "host.%s" (system-name))))
(when (boundp 'my/loc-tag)
(org-journal-tags-prop-apply-delta :add (list my/loc-tag))))
There are two ways how org-journal can be encrypted:
- With org-crypt, by setting
- With epa, by setting
Both ways are supported by this package (I use the first). The decryption of entries takes some time, but this is alleviated by caching.
The cache is stored in the
org-journal-tags--files-cache variable, so in principle, someone could come to your computer and inspect the value of this variable (who would ever do that?). If that’s an issue, you can do something like:
(run-with-idle-timer (* 60 15) t #'org-journal-tags-cache-reset)
To clear the cache on Emacs being idle after 15 minutes.
Also, as said above,
org-journal-tags uses its own database, which is more like persistent cache for tags and references. You can encrypt it as well with epa by adding
.gpg to the
(setq org-journal-tags-db-file (concat user-emacs-directory "var/org-journal-tags/index.gpg"))
The database is also stored in memory in
org-journal-tags-db variable, so once again, someone could inspect the value of the variable or just run
To avoid that, you can manually run
M-x org-journal-tags-db-unload or add it to
(run-with-idle-timer (* 60 15) t #'org-journal-tags-db-unload)
If you have everything set up correctly, encrypting a file shouldn’t ask for a passphrase, so this function can be run automatically.
This package provides an API for doing queries from the Lisp code.
The central function there
org-journal-tags-query, which has an interface corresponding to the flags in the query constructor. Take a look at its docstring for more info.
Also, you can use some of the following operations on the set of journal references:
org-journal-tags--query-merge-refs- merge intersecting references within one set
org-journal-tags--query-sort-refs- order references by date
org-journal-tags--string-extract-refs- collect strings corresponding to references
This package turned out to be almost as long and complex as org-journal itself, and it also introduces some new dependencies. Hence I decided it would be better off as a separate package.
Also, I want to list some sources of inspiration. The database logic is heavily inspired by elfeed. The UI with Emacs widgets for tags &
completing-read-multiple and the tagging system in general is inspired by notmuch. Finally, transient.el and magit-section are the UI packages that made this one possible, or at least much easier to implement.
