Full description


Org-transclusion lets you insert a copy of text content via a file link or ID link within an Org file. It lets you have the same content present in different buffers at the same time without copy-and-pasting it. Edit the source of the content, and you can refresh the transcluded copies to the up-to-date state. Org-transclusion keeps your files clear of the transcluded copies, leaving only the links to the original content.

A complete user manual is available online or Emacs in-system as an Info node `(org-transclusion)': (C-h i and find the Org-transclusion node).

For installation and minimum configuration, refer to Installation below or the user manual: online or Info node `(org-transclusion)Installation'

Getting Started in the user manual will get you started in 5 minutes: online or Info node `(org-transclusion)Getting Started'.

For customization, refer to the customization group `org-transclusion' or user manual: online or Info node `(org-transclusion)Customizing'.

1 Example Use Cases & Main Features

Here are some real use cases that users have shared with the author, including his own.

Book writing
You have a collection of notes. You can quickly transclude paragraphs and sections from your notes and put together a draft. As transclusions are links, it's easy to re-organize them into different sequences to see which way works the best.
Academic writing
You have a collection of quotes and notes from your research and literature review. Transclude relevant elements of quotes and notes into different papers. You can keep your collection as the central repository of your research.
Technical writing
You write technical documents for software. Transclude relevant lines of code into the document. As the code is only transcluded, you can keep the document up-to-date as the code evolves.
Project status reports
You work on multiple projects at the same time and need to report to different project managers. Transclude relevant parts of your work notes and logs into respective project reports. You can keep a single collection of your work notes and logs.

Main Features:

  • Insert a copy of text content via a file link or ID link into an Org file
  • Work with any text file such as program source code, plain text, Markdown, or other Org files
  • Keep the file system clear of the copies of text content – Org-transclusion tries hard to save only the links to the file system
  • For Org files, use different headline levels from the source Org file
  • For Org files, use filters to include only relevant elements (e.g. filter out properties in the transclusions)
  • For program source and plain text files, transclude a certain lines or dynamically specify the from/to lines to keep the transclusion always up-to-date with the evolving source files
  • For program source files, transclude parts or whole code directly into Org's source block to leverage the rich Org features including noweb style syntax
  • Extend Org-transclusion with its extension framework

2 Installation

This package is available on:

  • GNU ELPA (releases only; equivalent to MELPA-Stable)
  • GNU-devel ELPA (unreleased development branch; equivalent to MELPA)

GNU ELPA should be already set up in your Emacs by default. If you wish to add GNU-devel ELPA, simply add its URL to package-archives like this:

(add-to-list 'package-archives
	     '("gnu-devel" . "") :append)

Refresh the archive with M-x package-refresh-contents RET and you can do M-x package-install RET org-transclusion to install it. Alternatively, you can use package-list-packages.

After installation, you can start using Org-transclusion with no additional configuration. Below are some example keybindings that can be put into your Emacs configuration.

(define-key global-map (kbd "<f12>") #'org-transclusion-add)
(define-key global-map (kbd "C-n t") #'org-transclusion-mode)

For Doom users, you would need to do something like this below to install the package and configure the keybindings.

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

* Current

  - Fix: #131. For non-Org files, now the transcluded text respects the indent
         level of the #+transclude keyword.  This does not affect Org files.

* Version 1.2.0

  - Feature ::

    - add: org-transclusion-after-add-hook

  - Fix ::

    - fix: org-transclusion-map now inherits org-mode-map (thanks to ag91 [1])
    - fix: reverting 252ec675; shouldn't remove the extra space at the end of
           transclusions from Org
    - fix: #115 allow adding #+name, etc. before #+transclude keyword
           (don't remove affiliated keywords when org-transclusoin-remove)

* Version 1.1.1

  - Fix ::

    - Fix rare but destructive issue where buffer text content could be deleted
      by removing a transclusion.  This could happen by killing a second Emacs
      instance (batch or online) or buffer, while the first Emacs keeps
      transclusions added

  - Other:

    - User Manual now refers to v1.1.x

* Version 1.1.0

  - Change ::

    - add:inhibit-read-only: fix:Org export errors with read-only
      With this, noweb expansion works now (limitation removed)

  - Fix ::

    - fix:#105 org-element--cache issue for Org v9.6
      Remove use of silent-modificaiton & inhibit-modification-hook
    - fix:add-all not to stop with error in one trasclusion
    - fix:Remove extra space/line added to Org elements transcluded

  - Other ::
    - README, Info doc user manual, online user manual
* Version 1.0.1

  - Add .elpaignore
  - Bump up version only to enable ELPA; no functional changes

* Version 1.0.0

  - Initial version available on ELPA (

  - 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

† Changes before Version 1.0.0 are in CHANGELOG file.
