Org-transclusion

Transclusion is the ability to include content from one file into another by reference. Org-transclusion is an Org Mode version of it. It lets you insert a copy of text content via a file link or ID link within an Org file. It is my take on the idea by John Kitchin.

When I start writing a long-form material, I want to begin with looking through my notes and assemble relevant ones to form a basis of the first draft quickly. As I organise my notes in a repository, I also want to avoid having multiple copies of notes flying around.

Transclusion helps me do this.

I am dabbling in the Zettelkasten method with using Org-roam to feed my ideas into the repository. As such, although Org-transclusion is a standalone package, I would like to keep workflow seamless between Org-roam and Org-transclusion.

Installation

This package is not available on MELPA or ELPA. Manual installation is required.

Download or clone this repo, put all the .el files in it into your load-path, and put something like this in your init file.

(with-eval-after-load 'org
  (add-to-list  'load-path "path/to/org-transclusion/")
  (require 'org-transclusion)
  (define-key global-map (kbd "<f12>") #'org-transclusion-add)
  (define-key global-map (kbd "C-n t") #'org-transclusion-mode))

It is important that you get all the .el files ready, not just org-transclusion.el. As at the time of this writing, the live-sync feature is contained in text-clone.el (also available in this repo) and some new features and extensions are made available as separate .el files. You will need to have all the .el files to use Org-transclusion as a package.

If you use Doom and packages such as Straight, etc. to install files from GitHub repositories, you can do something like this below (it’s an example using Doom’s package! macro).

;; In ~/.doom.d/package.el
(package! org-transclusion
  :recipe (:host github
           :repo "nobiot/org-transclusion"
           :branch "main"
           :files ("*.el")))

For Doom, add use-package! to load the package by adding something like this in the code excerpt below in your config.el.

As of v0.2.0, some commands are defined with autoload. This means that adding some properties such as :defer lets you lazy-load the org-transclusion package. Please consult Doom’s documentation for further instruction (I don’t use Doom, but I have lightly tested this snippet). There are other ways to configure Doom; also refer to comments in issue #79 (thank you, @Ma-Nu-El).

;; In ~/.doom.d/config.el
(use-package! org-transclusion
  :defer
  :after org
  :init
  (map!
   :map global-map "<f12>" #'org-transclusion-add
   :leader
   :prefix "n"
   :desc "Org Transclusion Mode" "t" #'org-transclusion-mode))

Getting Started

The basic idea of Org-transclusion is simple: insert a copy of text content via a file link or ID link within an Org file. This is an Org Mode version of transclusion.

To transclude content via a reference, use one of the following commands:

org-transclusion-make-from-link
org-transclusion-add
org-transclusion-add-all

For example, if you have an ID link in your Org file like this:

[[id:20210501T171427.051019][Bertrand Russell]]

Put your cursor somewhere on this link and call M-x org-transclusion-make-from-link. That inserts a “transclusion” keyword like this in the next empty line:

#+transclude: [[id:20210501T171427.051019][Bertrand Russell]]

Put your cursor somewhere on this keyword line and call M-x org-transclusion-add, and you will see the content the ID points to be copied over, replacing the transclude keyword.

The transcluded text is read-only but you can copy it and export it as normal text. Org-transclusion remembers where it has transcluded the text from (its source buffer). You can call a number of useful commands with a single letter (by default).

For example, you can press o to open the source buffer of the transclusion at point, or O (capital “o”) to move to it. Press g to refresh the transclusion. Press e to start live-sync edit. For more detail, inspect the documentation of each command.

This single-letter-context-menu is defined in org-transclusion-map. The default keybindings are shown below. Adapt them to your liking, especially if you use vim keybindings with Evil Mode, etc.

key             binding
---             -------

C-c             Prefix Command
TAB             org-cycle
D               org-transclusion-demote-subtree
O               org-transclusion-move-to-source
P               org-transclusion-promote-subtree
d               org-transclusion-remove
e               org-transclusion-live-sync-start
g               org-transclusion-refresh
o               org-transclusion-open-source

C-c C-c         org-ctrl-c-ctrl-c

This should get you started with Org-transclusion. There are more options and customizing options available for you to fine-tune the text contents you transclude. More about them in README below.

As your next step, I recommend the section on filtering Org elements per transclusion, which shows features that give you the power to control what part of the source to transclude in the way you like and let you experiment on the fly.

Usage

Org-transclusion mode, activate, and deactivate

Org-transclusion is a local minor mode; however, you do not need to explicitly call org-transclusion-mode. The minor mode is intended to be just a convenient wrapper to let you easily toggle between activate and deactivate.

As you saw in the Getting Started section above, calling org-transclusion-add or org-transclusion-add-all is enough to add transclusions in your current buffer.

The minor mode is automatically turned on locally for your current buffer through one of these commands. All it does is to call org-transclusion-activate to activate hooks and some other variables. Their main purpose is to keep files in the filesystem clear of the transcluded content.

Turn off the minor mode or use org-transclusion-deactivate; you will remove all the transclusions in the current buffer and clear the hooks and other setup variables.

If you prefer, you can use org-transclusion-mode as your entry command for transclusion. When customizable variable org-transclusion-add-all-on-activate is non-nil (it is t by default), turning on the minor mode calls the org-transclusion-add-all command to attempt to add all transclusions automatically in the current buffer.

You can control whether or not transclusions are to be added automatically per transclude keyword. By default, org-transclusion-add-all (it is also used by org-transclusion-mode) will work on every transclude keyword in the buffer. Add :disable-auto property to a keyword as shown in the example below; add-all skips transclude keywords with it.

#+transclude: [[file:path/to/file.org]] :disable-auto

You can override the :disable-auto property by manually calling org-transclusion-add at point.

Org links supported

Transclusion has been tested to work for the following types of links:

File link for an entire org file/buffer; e.g. [[file:~/org/file.org][My Org Notes]]
File link with ::*heading
File link with ::#custom-id
File link with ::name for blocks (e.g. blocked quotations), tables, and links
File link with ::dedicated-target; this is intended for linking to a paragraph. See below.
ID link id:uuid
File link for non-org files (tested with .txt and .md); for these, the whole buffer gets transcluded

Note search-options ::/regex/ and ::number do not work as intentended.

For transcluding a specific paragraph, there are two main ways: Org Mode’s dedicated-target and :only-contents property.

For dedicated targets, the target paragraph must be identifiable by a dedicated target with a <<paragraph-id>>:

Lorem ipsum dolor sit amet, consectetur adipiscing elit.
Suspendisse ac velit fermentum, sodales nunc in,
tincidunt quam. <<paragraph-id>>

It is generally assumed that the paragraph-id is placed after its content, but it is not an absolute requirement; it can be in the beginning (before the content) or in the middle of it.

For the :only-contents property, refer to sub-section Filtering Org elements per transclusion.

Controlling levels of headlines in transclusions

You can specify a different level of transcluded headlines than that of the source Org file.

Use the :level property with a value of single digit number from 1 to 9 like this example below.

#+transclude: [[file:path/to/file.org::*Headline]] :level 2

The top level of the transcluded headline will set to the value of :level property – in this example, level 2 regardless of that in the source. When the headline contains sub-headlines, they will be all automatically promoted or demoted to align according to how many levels the top of the subtree will move.

When you transclude an entire Org file, it may contain multiple subtrees. In such cases, the top-most level among the subtrees will be set according to the :level property; the rest of headlines in the buffer will align accordingly.

Filtering Org elements per transclusion

You can control what elements to include in many different ways with using various filters. The filters work in two layers: customizable variable and properties per transclude keyword.

The following two customizable variables are applicable to all transclusions globally. You can think of them as the global default.

org-transclusion-exclude-elements: This customizable variable globally defines the exclusion filter for elements. It is a list of symbols; the acceptable values can be seen by inspecting org-element-all-elements. The default is to exclude property-drawer.
Refer also to the sub-section on this user option.
org-transclusion-include-first-section: This customizing variable globally defines whether or not to include the first section of the source Org file. The first section is the part before the first headline – that’s the section that typically contains #+title, #+author, and so on. Many people also write notes in it without adding any headlines. Note that this user option’s default is now t (changed from nil as users seem to spend time to “correct” this issue). Turn it to t if you wish to transclude the content from the first section of your Org files. If you wish to exclude the “meta data” defined by #+title and others, exclude keyword as described in this section – these meta data are defined with using the keyword element of Org Mode.
Refer also to the sub-section on this user option.

In addition to the global user options above, you can fine-tune the default exclusion filter per transclusion. Add following properties to transclusions you wish to apply additional filters.

:only-contents: This property lets you exclude titles of headlines when you transclude a subtree (headline); you transclude only the contents. When the subtree contains sub-headlines, all the contents will be transcluded.
Add :only-contents without any value like this example:

#+transclude: [[file:path/to/file.org]] :only-contents

:exclude-elements: This property lets you add elements to exclude per transclusion on top of the variable org-transclusion-exclude-elements defines. You cannot remove the ones defined by it; thus, it is intended that you use the customizable variable as your global default and fine-tune it by the property per transclusion.
Add :exclude-elements with a list of elements (each one as defined by org-element-all-elements) separated by a space inside double quotation marks like this example:

#+transclude: [[file:path/to/file.org]] :exclude-elements "drawer keyword"

Combining `:only-contents` and `:exclude-elements`

You can combine :only-contents and :exclude-elements to control how you transclude a subtree. Refer to the example screen shots below (the colored labels are added to the images for illustration purposes and not part of the Emacs buffers).

Figure 1. Left. Three transclusions with different properties; Right. Source to be transcluded

Figure 2. Left. Only the root-level headline is transcluded

Figure 3. Left. Content of the entire subtree, including sub-headlines, is transcluded

Figure 3. Left. Combined; only the content of top-level headline is transcluded

Notes on excluding the headline element

If you add headline as a list of elements to exclude, you exclude sub-headlines within your subtrees. You will still transclude the contents of the top-most level of the subtrees.

If you are transcluding only one subtree, this should be intuitive. If you transclude a whole buffer, you might be transcluding multiple subtrees. In some cases, this can be a little anti-intuitive. In the following examples, you will be transcluding three subtrees – even though the first headline levels are lower than the third one, the first two are still the top-most level of their own respective subtrees.

** Headline 1
   Content of Headline 1
** Headline 2
   Content of Headline 2
* Headline 3
  Content of Headline

Live-sync edit

Experimental. You can start live-sync edit by pressing e (by default) on a text element you want to edit. This will put a colored overlay on top of the region being live-synced and brings up another buffer that visits the source file of the transclusion. The source buffer will also have a corresponding overlay to the region being edited and live-synced.

If you have other windows open, they will be temporarily hidden – Org-transclusion will remembers your current window layout and attempts to recover it when you exit live-sync edit.

In the live-sync edit region, you can freely type to edit the transclusion or source regions; they will sync simultaneously.

Once done with editing, press C-c C-c to exit live-sync edit. The key is bound to org-transclusion-live-sync-exit. It will turn off the live sync edit but keep the transclusion on.

In the live-sync edit region, the normal yank command (C-y) is replaced with a special command org-transclusion-live-sync-paste. This command lets the pasted text inherit the text-properties of the transcluded region correctly; the normal yank does not have this feature and thus causes some inconvenience in live-sync edit. If you use vim keybindings (e.g. evil-mode), it is advised that you review the default keybindings. You can customize the local keybindings for the live-sync region by org-transclusion-live-sync-map.

Note: that during live-sync edit, file’s content gets saved to the filesystem as is – i.e. the transcluded text will be saved instead of the #+transclude: keyword. If you kill buffer or quit Emacs, other hooks will still remove the transclusion to keep the file clear of the transcluded copy, leaving only the keyword in the file system.

key                   binding
---                   -------

C-c                   Prefix Command
C-y                   org-transclusion-live-sync-paste

C-c C-c               org-transclusion-live-sync-exit

*Also inherits ‘org-mode-map’

Transclude source file into src-block

You can transclude a source file into an Org’s src block. Use the :src property and specify the language you would like to use like this:

#+transclude: [[file:../../test/python-1.py]] :src python

The content you specify in the link gets wrapped into a src-block with the language like this:

#+begin_src python
[... content of python-1.py]
#+end_src

Use :rest property to define additional properties you would like to add for the src-block. The double quotation marks are mandatory for the :rest property.

#+transclude: [[file:../../test/python-3.py]]  :src python :rest ":session :results value"

The source block will have the additional properties:

#+begin_src python :session :results value

Transclude range of lines for text and source files

`:lines` property to specify a range of lines

You can specify a range of lines to transclude from a source and text file. Use the :lines property like this.

#+transclude: [[file:../../test/test.txt]] :lines 3-5

The rage is specified by the number “3-5”; in this case, lines from 3 to 5, both lines inclusive.

To transclude a single line, have the the same number in both places (e.g. 10-10, meaning line 10 only).

One of the numbers can be omitted. When the first number is omitted (e.g. -10), it means from the beginning of the file to line 10. Likewise, when the second number is omitted (e.g. 10-), it means from line 10 to the end of file.

You can combine the :lines property with the :src property to transclude only a certain range of source files (Example 1 below).

For Org’s file links, you can use search options specified by the “::” (two colons) notation. When a search finds a line that includes the string, the Org-transclude counts it as the starting line 1 for the :lines property.

Example 1: This transcludes the four lines of the source file from the line that contains string “id-1234” (including that line counted as line 1).

#+transclude: [[file:../../test/python-1.py::id-1234]] :lines 1-4 :src python

Example 2: This transcludes only the single line that contains the line found by the search option for text string “Transcendental Ontology”

#+transclude: [[file:../../test/test.txt::Transcendental Ontology]] :lines 1-1

Note search-options ::/regex/ and ::number do not work as intended.

`:end` property to specify a search term to dynamically look for the end of a range

You can add :end property and specify the search term as its value. Surround the search term with double quotation marks (mandatory).

See Example 3 below. This transclusion will look for id-1234 as the beginning line of the range as specified by the search option ::id-1234 in the link. With the :end property, the search term id-1234 end here defines the end of the range. The search looks for id-123 end here in the body text, and use the line one before the one where the text is find (thus, the transcluded range will not contain id-1234 end here).

You can also combined :lines property with :end property. It will only displace the beginning, and the end part of the range (the second number after the hyphen “-“) is ignored. In the same example, the beginning of the range is the one line after the line where “id-1234” is found; it’s the “second line, or line 2”. Instead of transcluding until the end of the buffer, the end is defined by the :end property.

Example 3:

#+transclude: [[file:../../test/python-1.py::id-1234]] :lines 2- :src python :end "id-1234 end here"

Extensions - Support `org-indent-mode`

Org-transclusion provides a simple extension framework, where you can use customize to selectively add new features. Currently there are two extensions provided. Support for org-indent-mode is an extension, which is inactive by default.

(on by default) org-transclusion-src-lines: Add features for :src and :lines properties to #+transclude. It is meant for non-Org files such as program source and text files
(off by default) org-transclusion-indent-mode: Support org-indent-mode

If you use customize, the features are loaded automatically. Note that it does not “unload” the feature until you relaunch Emacs.

If you do not use customize (e.g. Doom), you may need to explicitly require an extension. For example, to activate org-transclusion-indent-mode, you might need to add something like this in your configuration file.

;; Ensure that load-path to org-transclusion is already added
;; (add-to-list  'load-path "path/to/org-transclusion/")
(add-to-list 'org-transclusion-extensions 'org-transclusion-indent-mode)
(require 'org-transclusion-indent-mode)

Customizing

You can customize settings in the org-transclusion group.

org-transclusion-extensions: Defines extensions to be loaded with org-transclusion.el. If you use customize, the extensions are loaded by it. If you don’t, you likely need to explicitly use require to load them.
org-transclusion-add-all-on-activate: Defines whether or not all the active transclusions (with t) get automatically transcluded on minor mode activation (org-transclusion-mode). This does not affect the manual activation when you directly call org-transclusion-activate
org-transclusion-exclude-elements: See sub-section below
org-transclusion-include-first-section: See sub-section below
org-transclusion-open-source-display-action-list: You can customize the way the org-transclusion-open-source function displays the source buffer for the transclusion. You specify the “action” in the way defined by the built-in display-buffer function. Refer to its in-system documentation (with C-h f) for the accepted values. M-x customize can also guide you with the types of values with the widget.
org-transclusion-mode-lighter: Define the lighter for Org-transclusion minor mode. The default is ” OT”.

Customizable filter to exclude certain Org elements

Set customizable variable org-transclusion-exclude-elements to define which elements to be excluded in the transclusion.

The filter works for all supported types of links within an Org file when transcluding an entire Org file, and parts of it (headlines, custom ID, etc.). There is no filter for non-Org files.

It is a list of symbols, and the default is (property-drawer). The accepted values are the ones defined by org-element-all-elements (Org’s standard set of elements; refer to its documentation for an exhaustive list).

You can also fine-tune the exclusion filter per transclusion. Refer to the sub-section on filtering Org elements per transclusion.

Include the section before the first headline (Org file only)

You can include the first section (section before the first headline) of an Org file. It is toggled via customizable variable org-transclusion-include-first-section. Its default value is t. Set it to t (or non-nil) to transclude the first section. It also works when the first section is followed by headlines.

Faces & fringe bitmap

Face for the `#+transclude` keyword

You can set your own face to the #+transclude keyword with using the org-transclusion-keyword face.

Faces for the fringes next to transcluded region and source region

If the fringes that indicate transcluding and source regions are not visible in your system (e.g. Doom), try adding background and/or foreground colors to these custom faces.

org-transclusion-source-fringe
org-transclusion-fringe

Here is an example image from this issue:

To customize a face, it’s probably the easiest to use M-x customize-face. If you want to use Elisp for some reason (e.g. on Doom), something like this below should set faces. Experiment with the colors of your choice. By default, the faces above have no values.

(set-face-attribute
 'org-transclusion-fringe nil
 :foreground "green"
 :background "green")

For colors, where “green” is, you can also use something like “#62c86a” (Emacs calls it “RGB triple”; you can refer to in-system manual Emacs > Colors). You might also like to refer to a list of currently defined faces in your Emacs by list-faces-display.

Other faces:

org-transclusion-source
org-transclusion-source-edit
org-transclusion
org-transclusion-edit

I do not know if bitmap can be customizable after it’s been defined (TBC).

org-transclusion-fringe-bitmap: It is used for the fringe that indicates the transcluded region. It works only in a graphical environment (not in terminal).

Keybindings

org-transclusion-map
org-transclusion-live-sync-map

Tips

Moving from 0.0.x to 0.1.x

GitHub user @lytex has provided a bash script that converts old syntax to the new one in this issue. Thank you.

I’ve made a bash one-liner to migrate from the old syntax to the new one (manages transclude and hlevel -> level), feel free to copy or link it in the docs

Known Limitations

Note this section is still incomplete, far from being exhaustive for “known” limitations.

Org link’s search-options ::/regex/ and ::number do not work as intended.

org-transclusion-live-sync-start does not support all Org elements

For transclusions of Org elements or buffers, live-sync works only on the following elements: center-block, drawer, dynamic-block, latex-environment, paragraph, plain-list, quote-block, special-block, table, and verse-block.

It is known that live-sync does not work for the other elements; namely: comment-block, export-block, example-block, fixed-width, keyword, src-block, and property-drawerd.

More technical reason for this limitation is documented in the docstring of function org-transclusion-live-sync-enclosing-element.

Work is in progress to lift this limitation but I’m still experimenting different ideas.

org-indent-mode may not work well with Org-transclusion

A new extension has been added to support org-indent-mode Refer to this section.

Doom’s customization may interfere with Org-transclusion

Refer to this issue. The symptom is that in your Doom and you get an error message that includes this: “progn: ‘recenter’ing a window that does not display current-buffer.” Adding this in your configuration has been reported to fix the issue:

(advice-remove 'org-link-search '+org--recenter-after-follow-link-a)

It is probably rather drastic a measure. I will appreciate it if you find a less drastic way that works. Thank you.

Org refile does not work “properly” on the transcluded headlines

Refer to issue #20. I don’t intend to support this – refile the source, not the transcluded copy.

Org-transclusion does not support expansion of noweb references when a transcluded source block code has them

Refer to issue #86. You will get “Text-only” error when export tries to expand the noweb references into the source code.

Changelog

Main features and changes only.

Current

Feature

: :end property and a search term to dynamically define a range of lines to transclude for text and source code block

Change

Now user option org-transclusion-include-first-section’s default value is changed to t. This seems to be more intuitive for more users

Fix

org-transclusion-before-kill now checks if the buffer to be killed contains any transclusion AND it is visting a file before saving. This fixes some issues related to temp buffers, etc.

fix: search options for src-lines extension for :lines, :src, and :end properties

The first headline, when present, is treated as the first headline, thus :exclude-element “headline” affects its sub-headlines; this means that the content of the first headline is transcluded even when with “headline” in the list of excluded elements.

0.1.2

e08df47 * add: live-sync for non-Org text file: So far Non-Org text files could be transcluded but live-sync was not available. This version enables live-sync for them. Only for the whole file at the moment (ability to specify parts of a text file is considered)
a576b34 * add: text-clone library (rename): Live-sync features are now factored out into text-clone as a standalone library (available with text-clone.el also included in this repo). Refactored so that org-transclusion uses (and requires) text-clone.

0.1.1

49f03b1 * feat: current-indentation: Org-transclusion now keeps the original indentation of the keyword. When a transclusion text region is removed, its keyword will be indented as it was
d55fc39 * chg: save-buffer hooks: Instead of blindly deactivate and activate all transclusions with t flag, this variable is meant to provide mechanism to deactivate/activate only the transclusions currently in effect to copy a text content.
64fd182 * add: remove live-sync overlays when deleted: Closes issue #8 Adding a mechanism to remove both of the live-sync overlays (transclusion and source) when transclusion is completely deleted. This solves the problem of a source overlay to be orphaned in such cases.

0.1.0

As described in this version.

Original idea by John Kitchin

https://github.com/alphapapa/transclusion-in-emacs#org-mode

{O} transcluding some org-elements in multiple places [2016-12-09 Fri] John Kitchin asks:

I have an idea for how I could transclude “copies” or links to org-elements in multiple places and keep them up to date. A prototypical example of this is I have a set of org-contacts in one place, and I want to create a new list of people for a committee in a new place made of “copies” of the contact headlines. But I do not really want to duplicate the headlines, and if I modify one, I want it reflected in the other places. I do not want just links to those contacts, because then I can not do things with org-map-entries, and other org-machinery which needs the actual headlines/properties present. Another example might be I want a table in two places, but the contents of them should stay synchronized, ditto for a code block.

This idea was inspired by https://github.com/gregdetre/emacs-freex.

The idea starts with creating (wait for it…) a new link ;) In a document where I want to transclude a headline, I would enter something like:

transclude:some-file.org::*headline title

Then, I would rely on the font-lock system to replace that link with the headline and its contents (via the :activate-func link property), and to put an overlay on it with a bunch of useful properties, including modification hooks that would update the source if I change the the element in this document, and some visual indication that it is transcluded (e.g. light gray background/tooltip).

I would create a kill-buffer hook function that would replace that transcluded content with the original link. A focus-in hook function would make sure the transcluded content is updated when you enter the frame. So when the file is not open, there is just a transclude link indicating what should be put there, and when it is open, the overlay modification hooks and focus hook should ensure everything stays synchronized (as long as external processes are not modifying the contents).

It seems like this could work well for headlines, and named tables, src blocks, and probably any other element that can be addressed by a name/ID.

Text-Clone

text-clone.el is an extension of text-clone functions written as part of GNU Emacs in subr.el. The first adaption to extend text-clone functions to work across buffers was published in StackExchange by the user named Tobias in March 2020. It can be found at https://emacs.stackexchange.com/questions/56201/is-there-an-emacs-package-which-can-mirror-a-region/56202#56202. The text-clone library takes this line of work further.

Notes on pull requests and FSF copy right assignment

I am considering of submitting Org-transclusion for inclusion into the upstream Org Mode at some point, hopefully towards the end of year 2021. This was suggested a while ago in a Reddit discussion.

This means that anyone who is making a substantive code contribution will need to “assign the copyright for your contributions to the FSF so that they can be included in GNU Emacs” (Org Mode website).

I have not started a conversation about it in the Org Mode mailing list nor have I done the formal procedure for the copy right assignment yet. It will be at the discretion of Org Mode’s maintainers to decide on my request for inclusion when I submit it.

Please consider this when you create a pull request for Org-transclusion.

Thank you!
