It reproduces some of [[https://roamresearch.com/][Roam Research's]] [fn:roam] key features within [[https://orgmode.org/][Org-mode]]. Org-roam allows for effortless non-hierarchical note-taking: with Org-roam, notes flow naturally, making note-taking fun and easy. Org-roam augments the Org-mode syntax, and will work for anyone already using Org-mode for their personal wiki. Org-roam leverages the mature ecosystem around Org-mode. For example, it has first-class support for [[https://github.com/jkitchin/org-ref][org-ref]] for citation management, and is able to piggyback off Org's excellent LaTeX and source-block evaluation capabilities. Org-roam provides these benefits over other tooling: - *Privacy and Security:* Your personal wiki belongs only to you, entirely offline and in your control. Encrypt your notes with GPG. - *Longevity of Plain Text:* Unlike web solutions like Roam Research, the notes are first and foremost plain Org-mode files -- Org-roam simply builds an auxiliary database to give the personal wiki superpowers. Having your notes in plain-text is crucial for the longevity of your wiki. Never have to worry about proprietary web solutions being taken down. The notes are still functional even if Org-roam ceases to exist. - *Free and Open Source:* Org-roam is free and open-source, which means that if you feel unhappy with any part of Org-roam, you may choose to extend Org-roam, or open a pull request. - *Leverage the Org-mode ecosystem:* Over the decades, Emacs and Org-mode has developed into a mature system for plain-text organization. Building upon Org-mode already puts Org-roam light-years ahead of many other solutions. - *Built on Emacs:* Emacs is also a fantastic interface for editing text, and Org-roam inherits many of the powerful text-navigation and editing packages available to Emacs. * Target Audience Org-roam is a tool that will appear unfriendly to anyone unfamiliar with Emacs and Org-mode, but it is also extremely powerful to those willing to put effort inn mastering the intricacies. Org-roam stands on the shoulders on giants. Emacs was first created in 1976, and remains the tool of choice for many for editing text and designing textual interfaces. The malleability of Emacs allowed the creation of Org-mode, an all-purpose plain-text system for maintaining TODO lists, planning projects, and authoring documents. Both of these tools are incredibly vast and require significant time investment to master. Org-roam assumes only basic familiarity with these tools. It is not difficult to get up and running with basic text-editing functionality, but one will only fully appreciate the power of building Roam functionality into Emacs and Org-mode when the usage of these tools become more advanced. One key advantage to Org-roam is that building on top of Emacs gives it malleability. This is especially important for note-taking workflows. It is our belief that note-taking workflows are extremely personal, and there is no one tool that's perfect for you. Org-mode and Org-roam allows you to discover what works for you, and build that perfect tool for yourself. If you are new to the software, and choose to take this leap of faith, I hope you find yourself equally entranced as Neal Stephenson was. #+BEGIN_QUOTE Emacs outshines all other editing software in approximately the same way that the noonday sun does the stars. It is not just bigger and brighter; it simply makes everything else vanish. – Neal Stephenson, In the Beginning was the Command Line (1998) #+END_QUOTE * A Brief Introduction to the Zettelkasten Method Org-roam provides utilities for maintaining a digital slip-box. This section aims to provide a brief introduction to the "slip-box", or "Zettelkasten" method. By providing some background on the method, we hope that the design decisions of Org-roam will become clear, and that will aid in using Org-roam appropriately. In this section we will introduce terms commonly used within the Zettelkasten community and the Org-roam forums. The Zettelkasten is a personal tool for thinking and writing. It places heavy emphasis on connecting ideas, building up a web of thought. Hence, it is well suited for knowledge workers and intellectual tasks, such as conducting research. The Zettelkasten can act as a research partner, where conversations with it may produce new and surprising lines of thought. This method is attributed to German sociologist Niklas Luhmann, who using the method had produced volumes of written works. Luhmann's slip-box was simply a box of cards. These cards are small -- often only large enough to fit a single concept. The size limitation encourages ideas to be broken down into individual concepts. These ideas are explicitly linked together. The breakdown of ideas encourages tangential exploration of ideas, increasing the surface for thought. Making linking explicit between notes also encourages one to think about the connections between concepts. At the corner of each note, Luhmann ascribed each note with an ordered ID, allowing him to link and jump between notes. In Org-roam, we simply use hyperlinks. Org-roam is the slip-box, digitalized in Org-mode. Every zettel (card) is a plain-text, Org-mode file. In the same way one would maintain a paper slip-box, Org-roam makes it easy to create new zettels, pre-filling boilerplate content using a powerful templating system. ** Fleeting notes A slip-box requires a method for quickly capturing ideas. These are called *fleeting notes*: they are simple reminders of information or ideas that will need to be processed later on, or trashed. This is typically accomplished using ~org-capture~ (see info:org#Capture), or using Org-roam's daily notes functionality (see [[*Daily-notes][Daily-notes]]). This provides a central inbox for collecting thoughts, to be processed later into permanent notes. ** Permanent notes Permanent notes are further split into two categories: *literature notes* and *concept notes*. Literature notes can be brief annotations on a particular source (e.g. book, website or paper), that you'd like to access later on. Concept notes require much more care in authoring: they need to be self-explanatory and detailed. Org-roam's templating system supports the addition of different templates to facilitate the creation of these notes. * Installation Org-roam can be installed using Emacs' package manager or manually from its development repository. ** Installing from MELPA Org-roam is available from Melpa and Melpa-Stable. If you haven't used Emacs' package manager before, you may familiarize yourself with it by reading the documentation in the Emacs manual, see info:emacs#Packages. Then, add one of the archives to =package-archives=: - To use Melpa: #+BEGIN_SRC emacs-lisp (require 'package) (add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/") t) #+END_SRC - To use Melpa-Stable: #+BEGIN_SRC emacs-lisp (require 'package) (add-to-list 'package-archives '("melpa-stable" . "http://stable.melpa.org/packages/") t) #+END_SRC Org-roam also depends on a recent version of Org, which can be obtained in Org's package repository (see info:org#Installation). To use Org's ELPA archive: #+BEGIN_SRC emacs-lisp (add-to-list 'package-archives '("org" . "https://orgmode.org/elpa/") t) #+END_SRC Once you have added your preferred archive, you need to update the local package list using: #+BEGIN_EXAMPLE M-x package-refresh-contents RET #+END_EXAMPLE Once you have done that, you can install Org-roam and its dependencies using: #+BEGIN_EXAMPLE M-x package-install RET org-roam RET #+END_EXAMPLE Now see [[*Post-Installation Tasks][Post-Installation Tasks]]. ** Installing from Apt Users of Debian 11 or later or Ubuntu 20.10 or later can simply install Org-roam using Apt: #+BEGIN_SRC bash apt-get install elpa-org-roam #+END_SRC Org-roam will then be autoloaded into Emacs. ** Installing from the Git Repository You may install Org-roam directly from the repository on [[https://github.com/org-roam/org-roam][GitHub]] if you like. This will give you access to the latest version hours or days before it appears on MELPA, and months (or more) before it is added to the Debian or Ubuntu repositories. This will also give you access to various developmental branches that may be available. Note, however, that development version, and especially any feature branches, may not always be in working order. You'll need to be prepared to do some debugging, or to manually roll-back to working versions, if you install from GitHub. Installing from GitHub requires that you clone the repository: #+begin_src bash git clone https://github.com/org-roam/org-roam.git /path/to/org/roam #+end_src where ~./path/to/org/roam~ is the location you will store your copy of the code. Next, you need to add this location to your load path, and ~require~ the Org-roam library. Add the following code to your ~.emacs~: #+begin_src elisp (add-to-list 'load-path "/path/to/org/roam") (require 'org-roam) #+end_src You now have Org-roam installed. However, you don't necessarily have the dependencies that it requires. These include: - dash - f - s - org - emacsql - emacsql-sqlite3 You can install this manually as well, or get the latest version from MELPA. You may wish to use [[https://github.com/jwiegley/use-package][use-package]], [[https://github.com/raxod502/straight.el][straight.el]] to help manage this. If you would like to install the manual for access from Emacs' built-in Info system, you'll need to compile the .texi source file, and install it in an appropriate location. To compile the .texi source file, from a terminal navigate to the ~/doc~ subdirectory of the Org-roam repository, and run the following: #+begin_src bash make infodir=/path/to/my/info/files install-info #+end_src Where ~/path/to/my/info/files~ is the location where you keep info files. This target directory needs to be stored in the variable `Info-default-directory-list`. If you aren't using one of the default info locations, you can configure this with the following in your ~.emacs~ file: #+begin_src elisp (require 'info) (add-to-list 'Info-default-directory-list "/path/to/my/info/files") #+end_src You can also use one of the default locations, such as: - /usr/local/share/info/ - /usr/share/info/ - /usr/local/share/info/ If you do this, you'll need to make sure you have write-access to that location, or run the above ~make~ command as root. Now that the info file is ready, you need to add it to the corresponding ~dir~ file: #+begin_src bash install-info /path/to/my/info/files/org-roam.info /path/to/my/info/files/dir #+end_src ** Post-Installation Tasks Org-roam requires ~sqlite3~ to be located on ~exec-path~. Please ensure that ~sqlite3~ is installed appropriately on your operating system. You can verify that this is the case by executing: #+BEGIN_SRC emacs-lisp (executable-find "sqlite3") #+END_SRC If you have ~sqlite3~ installed, and ~executable-find~ still reports ~nil~, then it is likely that the path to the executable is not a member of the Emacs variable ~exec-path~. You may rectify this by manually adding the path within your Emacs configuration: #+BEGIN_SRC emacs-lisp (add-to-list 'exec-path "path/to/sqlite3") #+END_SRC * Getting Started ** The Org-roam Node We first begin with some terminology we'll use throughout the manual. We term the basic denomination in Org-roam a node. We define a node as follows: #+begin_quote A node is any headline or top level file with an ID. #+end_quote For example, with this example file content: #+begin_src org :PROPERTIES: :ID: foo :END: ,#+title: Foo ,* Bar :PROPERTIES: :ID: bar :END: #+end_src We create two nodes: 1. A file node "Foo" with id ~foo~. 2. A headline node "Bar" with id ~bar~. Headlines without IDs will not be considered Org-roam nodes. Org IDs can be added to files or headlines via the interactive command ~M-x org-id-get-create~. ** Links between Nodes We link between nodes using Org's standard ID link (e.g. ~id:foo~). While only ID links will be considered during the computation of links between nodes, Org-roam caches all other links in the documents for external use. ** Setting up Org-roam Org-roam's primary capability comes from its aggressive caching: it crawls all files within ~org-roam-directory~, keeping a cache of all its links and nodes, and making sure that the cache is consistent. To first start using Org-roam, one needs to pick a location to store the Org-roam files. The directory that will contain your notes is specified by the variable ~org-roam-directory~. Org-roam searches recursively within ~org-roam-directory~ for notes. This variable needs to be set before any calls to Org-roam functions. For this tutorial, create an empty directory, and set ~org-roam-directory~: #+BEGIN_SRC emacs-lisp (make-directory "~/org-roam") (setq org-roam-directory "~/org-roam") #+END_SRC Next, we need to setup Org-roam to maintain cache consistency. This is achieved by running ~M-x org-roam-setup~. To ensure that Org-roam is available on startup, one can place this in their Emacs configuration: #+begin_src emacs-lisp (require 'org-roam) (org-roam-setup) #+end_src To build the cache manually, one can run ~M-x org-roam-db-build-cache~. Cache builds may take a while the first time, but is often instantaneous in subsequent runs because it only reprocesses modified files. ** TODO Creating New Notes Let us now create our first node. Call ~M-x org-roam-find-file~. This shows a list of titles for nodes that reside in ~org-roam-directory~. It should show nothing right now, since there are no notes in the directory. Entering the title of the note you wish to create, and pressing ~RET~ should begin the note creation process. This process uses ~org-capture~'s templating system, and can be customized (see [[*The Templating System][The Templating System]]). Using the default template, pressing ~C-c C-c~ finishes the note capture. For experienced ~org-capture~ users, the behavior of ~M-x org-roam-find-file~ may seem unfamiliar: after finishing a capture with ~C-c C-c~, you are returned not to the original buffer from which you called ~M-x org-roam-find-file~, but to a buffer pointing to the note you just created. For the usual ~org-capture~ behavior you can call ~M-x org-roam-capture~ instead of ~M-x org-roam-find-file~. Org-roam makes it easy to create notes, and link them together. To link notes together, we call ~M-x org-roam-insert~. This brings up a prompt with a list of title for existing notes. Selecting an existing entry will create and insert a link to the current file. Entering a non-existent title will create a new note with that title. Good usage of Org-roam requires liberally linking files: this facilitates building up a dense graph of inter-connected notes. Org-roam provides an interface to view backlinks. It shows backlinks for the currently active Org-roam note, along with some surrounding context. To toggle the visibility of this buffer, call ~M-x org-roam~. For a visual representation of the notes and their connections, Org-roam also provides graphing capabilities, using Graphviz. It generates graphs with notes as nodes, and links between them as edges. The generated graph can be used to navigate to the files, but this requires some additional setup (see [[*Roam Protocol][Roam Protocol]]). * TODO Node Properties ** TODO Standard Org properties ** TODO Aliases ** TODO Refs Refs are unique identifiers for files. For example, a note for a website may contain a ref: #+BEGIN_SRC org #+title: Google #+roam_key: https://www.google.com/ #+END_SRC These keys allow references to the key to show up in the backlinks buffer. For instance, with the example above, if another file then links to https://www.google.com, that will show up as a “Ref Backlink”. These keys also come in useful for when taking website notes, using the ~roam-ref~ protocol (see [[*Roam Protocol][Roam Protocol]]). [[https://github.com/jkitchin/org-ref][org-ref]] citation keys can also be used as refs: #+BEGIN_SRC org #+title: Neural Ordinary Differential Equations #+roam_key: cite:chen18_neural_ordin_differ_equat #+END_SRC #+CAPTION: org-ref-citelink [[file:images/org-ref-citelink.png]] You may assign multiple refs to a single file, for example when you want multiple papers in a series to share the same note, or an article has a citation key and a URL at the same time. * TODO The Org-roam Buffer * TODO Styling Org-roam * TODO Completion * TODO Encryption * TODO Org-roam protocol * TODO Diagnosing and Repair * TODO Building Extensions ** TODO Public Interface Database (for developers) - querying: (org-roam-db-query) - updating full database: (org-roam-db-sync) - update current file: (org-roam-db-update-file) - remove file from database: (org-roam-db-clear-file) Nodes: - List all nodes - Read a node in from completion - Get node at point Links: - Get backlinks for node Tags: - Add tag to node - delete tag for node - Get tags for node Aliases: - Add alias to node - Delete alias for node - Get aliases for node Ref: - Add ref to node Capture: Navigation: - Find or create a node - * TODO The Org-mode Ecosystem * TODO Frequently Asked Questions * The Templating System Rather than creating blank files on ~org-roam-insert~ and ~org-roam-find-file~, it may be desirable to prefill the file with templated content. This may include: - Time of creation - File it was created from - Clipboard content - Any other data you may want to input manually This requires a complex template insertion system. Fortunately, Org ships with a powerful one: ~org-capture~ (see info:org#capture). However, org-capture was not designed for such use. Org-roam abuses ~org-capture~, extending its syntax and capabilities. To first understand how org-roam's templating system works, it may be useful to look into basic usage of ~org-capture~. For these reasons, Org-roam capture templates are not compatible with regular ~org-capture~. Hence, Org-roam's templates can be customized by instead modifying the variable ~org-roam-capture-templates~. Just like ~org-capture-templates~, ~org-roam-capture-templates~ can contain multiple templates. If ~org-roam-capture-templates~ only contains one template, there will be no prompt for template selection. ** Template Walkthrough To demonstrate the additions made to org-capture templates. Here, we walkthrough the default template, reproduced below. #+BEGIN_SRC emacs-lisp ("d" "default" plain (function org-roam--capture-get-point) "%?" :file-name "%<%Y%m%d%H%M%S>-${slug}" :head "#+title: ${title}\n" :unnarrowed t) #+END_SRC 1. The template has short key ~"d"~. If you have only one template, org-roam automatically chooses this template for you. 2. The template is given a description of ~"default"~. 3. ~plain~ text is inserted. Other options include Org headings via ~entry~. 4. ~(function org-roam--capture-get-point)~ should not be changed. 5. ~"%?"~ is the template inserted on each call to ~org-roam-capture--capture~. This template means don't insert any content, but place the cursor here. 6. ~:file-name~ is the file-name template for a new note, if it doesn't yet exist. This creates a file at path that looks like ~/path/to/org-roam-directory/20200213032037-foo.org~. This template also allows you to specify if you want the note to go into a subdirectory. For example, the template ~private/${slug}~ will create notes in ~/path/to/org-roam-directory/private~. 7. ~:head~ contains the initial template to be inserted (once only), at the beginning of the file. Here, the title global attribute is inserted. 8. ~:unnarrowed t~ tells org-capture to show the contents for the whole file, rather than narrowing to just the entry. Other options you may want to learn about include ~:immediate-finish~. ** Org-roam Template Expansion Org-roam's template definitions also extend org-capture's template syntax, to allow prefilling of strings. We have seen a glimpse of this in [[*Template Walkthrough][Template Walkthrough]]. In org-roam templates, the ~${var}~ syntax allows for the expansion of variables, stored in ~org-roam-capture--info~. For example, during ~org-roam-insert~, the user is prompted for a title. Upon entering a non-existent title, the ~title~ key in ~org-roam-capture--info~ is set to the provided title. ~${title}~ is then expanded into the provided title during the org-capture process. Any variables that do not contain strings, are prompted for values using ~completing-read~. After doing this expansion, the org-capture's template expansion system is used to fill up the rest of the template. You may read up more on this on [[https://orgmode.org/manual/Template-expansion.html#Template-expansion][org-capture's documentation page]]. To illustrate this dual expansion process, take for example the template string: ~"%<%Y%m%d%H%M%S>-${title}"~, with the title ~"Foo"~. The template is first expanded into ~%<%Y%m%d%H%M%S>-Foo~. Then org-capture expands ~%<%Y%m%d%H%M%S>~ with timestamp: e.g. ~20200213032037-Foo~. All of the flexibility afforded by Emacs and Org-mode are available. For example, if you want to encode a UTC timestamp in the filename, you can take advantage of org-mode's ~%(EXP)~ template expansion to call ~format-time-string~ directly to provide its third argument to specify UTC. #+BEGIN_SRC emacs-lisp ("d" "default" plain (function org-roam--capture-get-point) "%?" :file-name "%(format-time-string \"%Y-%m-%d--%H-%M-%SZ--${slug}\" (current-time) t)" :head "#+title: ${title}\n" :unnarrowed t) #+END_SRC * Concepts and Configuration The number of configuration options is deliberately kept small, to keep the Org-roam codebase manageable. However, we attempt to accommodate as many usage styles as possible. All of Org-roam's customization options can be viewed via ~M-x customize-group org-roam~. ** Directories and Files This section concerns the placement and creation of files. - Variable: org-roam-directory This is the default path to Org-roam files. All Org files, at any level of nesting, are considered part of the Org-roam. - Variable: org-roam-db-location Location of the Org-roam database. If this is non-nil, the Org-roam sqlite database is saved here. It is the user’s responsibility to set this correctly, especially when used with multiple Org-roam instances. - Variable: org-roam-file-exclude-regexp Files matching this regular expression are excluded from the Org-roam. ** The Org-roam Buffer The Org-roam buffer displays backlinks for the currently active Org-roam note. - User Option: org-roam-buffer The name of the org-roam buffer. Defaults to ~*org-roam*~. - User Option: org-roam-buffer-position The position of the Org-roam buffer side window. Valid values are ~'left~, ~'right~, ~'top~, ~'bottom~. - User Option: org-roam-buffer-width Width of ~org-roam-buffer~. Has an effect only if ~org-roam-buffer-position~ is ~'left~ or ~'right~. - User Option: org-roam-buffer-height Height of ~org-roam-buffer~. Has an effect only if ~org-roam-buffer-position~ is ~'top~ or ~'bottom~. - User Option: org-roam-buffer-window-parameters Additional window parameters for the org-roam-buffer side window. For example one can prevent the window from being deleted when calling ~delete-other-windows~, by setting it with the following: ~(setq org-roam-buffer-window-parameters '((no-delete-other-windows . t)))~ ** Org-roam Files Org-roam files are created and prefilled using Org-roam's templating system. The templating system is customizable (see [[*The Templating System][The Templating System]]). ** Org-roam Faces Org-roam introduces several faces to distinguish links within the same buffer. These faces are enabled by default in Org-roam notes. - User Option: org-roam-link-use-custom-faces When ~t~, use custom faces only inside Org-roam notes. When ~everywhere~, the custom face is applied additionally to non Org-roam notes. When ~nil~, do not use Org-roam's custom faces. The ~org-roam-link~ face is the face applied to links to other Org-roam files. This distinguishes internal links from external links (e.g. external web links). The ~org-roam-link-current~ face corresponds to links to the same file it is in. The ~org-roam-link-invalid~ face is applied to links that are broken. These are links to files or IDs that cannot be found. * Inserting Links The preferred mode of linking is via ~file~ links to files, and ~id~ links for headlines. This maintains the strongest compatibility with Org-mode, ensuring that the links still function without Org-roam, and work well exporting to other backends. ~file~ links can be inserted via ~org-roam-insert~. Links to headlines can be inserted by navigating to the desired headline and calling ~org-store-link~. This will create an ID for the headline if it does not already exist, and populate the Org-roam database. The link can then be inserted via ~org-insert-link~. An alternative mode of insertion is using Org-roam's ~roam~ links. Org-roam registers this link type, and interprets the path as follows: - ~[[roam:title]]~ :: links to an Org-roam file with title or alias "title" - ~[[roam:*headline]]~ :: links to the headline "headline" in the current Org-roam file - ~[[roam:title*headline]]~ :: links to the headline "headline" in the Org-roam file with title or alias "title" - User Option: org-roam-link-title-format To distinguish between org-roam links and regular links, one may choose to use special indicators for Org-roam links. Defaults to ~"%s"~. If your version of Org is at least ~9.2~, consider styling the link differently, by customizing the ~org-roam-link~, and ~org-roam-link-current~ faces. - User Option: org-roam-link-auto-replace When non-nil, ~roam~ links will be replaced with ~file~ or ~id~ links when they are navigated to, and on file save, when a match is found. This is desirable to maintain compatibility with vanilla Org, but resolved links are harder to edit. Defaults to ~t~. * Completions Completions for Org-roam are provided via ~completion-at-point~. Completion suggestions are implemented as separate functions. Org-roam installs all functions in ~org-roam-completion-functions~ to ~completion-at-point-functions~. - Variable: org-roam-completion-functions The list of functions to be used with ~completion-at-point~. - User Option: org-roam-completion-ignore-case When non-nil, the ~roam~ link completions are ignore case. For example, calling ~completion-at-point~ within ~[[roam:fo]]~ will present a completion for a file with title "Foo". Defaults to ~t~. To use the completions from Org-roam with ~company-mode~, prepend ~company-capf~ to variable ~company-backends~. ** Link Completion ~roam~ links support auto-completion via ~completion-at-point~: simply call ~M-x completion-at-point~ within a roam link. That is, where the ~|~ character represents the cursor: - ~[[|]]~: completes for a file title - ~[[roam:]]~: completes for a file title - ~[[*|]]~: completes for a headline within this file - ~[[foo*|]]~: completes a headline within the file with title "foo" - ~[[roam:foo*|]]~ completes a headline within the file with title "foo" Completions account for the current input. For example, for ~[[f|]]~, the completions (by default) only show for files with titles that start with "f". - Function: org-roam-link-complete-at-point Do appropriate completion for the link at point. *** Link Completions Everywhere Org-roam is able to provide completions from the current word at point, enabling as-you-type link completions. However, this is disabled by default: the author believes that linking should be a deliberate action and linking should be performed with great care. Setting ~org-roam-completion-everywhere~ to ~t~ will enable word-at-point completions. - User Option: org-roam-completion-everywhere If non-nil, provide completions from the current word at point. That is, in the scenario ~this is a sent|~, calling ~completion-at-point~ will show completions for titles that begin with "sent". ** Tag Completion Org-roam facilitates the insertion of existing tags via ~completion-at-point~. That is, suppose you have notes with tags "foo", and "bar". Now, in a note, if you're on a line beginning with ~#+roam_tags:~, completions for these will appear as-you-type if they match. This functionality is implemented in ~org-roam-complete-tags-at-point~. * Navigating Around ** Index File As your collection grows, you might want to create an index where you keep links to your main files. In Org-roam, you can define the path to your index file by setting ~org-roam-index-file~. - Variable: org-roam-index-file Path to the Org-roam index file. The path can be a string or a function. If it is a string, it should be the path (absolute or relative to ~org-roam-directory~) to the index file. If it is is a function, the function should return the path to the index file. Otherwise, the index is assumed to be a note in ~org-roam-index~ whose title is ~"Index"~. - Function: org-roam-find-index Opens the Index file in the current ~org-roam-directory~. * Encryption One may wish to keep private, encrypted files. Org-roam supports encryption (via GPG), which can be enabled for all new files by setting ~org-roam-encrypt-files~ to ~t~. When enabled, new files are created with the ~.org.gpg~ extension and decryption are handled automatically by EasyPG. Note that Emacs will prompt for a password for encrypted files during cache updates if it requires reading the encrypted file. To reduce the number of password prompts, you may wish to cache the password. - User Option: org-roam-encrypt-files Whether to encrypt new files. If true, create files with .org.gpg extension. * Graphing Org-roam provides graphing capabilities to explore interconnections between notes. This is done by performing SQL queries and generating images using [[https://graphviz.org/][Graphviz]]. The graph can also be navigated: see [[*Roam Protocol][Roam Protocol]]. The entry point to graph creation is ~org-roam-graph~. - Function: org-roam-graph & optional arg file node-query Build and possibly display a graph for FILE from NODE-QUERY. If FILE is nil, default to current buffer’s file name. ARG may be any of the following values: - ~nil~ show the graph. - ~C-u~ show the graph for FILE. - ~C-u N~ show the graph for FILE limiting nodes to N steps. - ~C-u C-u~ build the graph. - ~C-u -~ build the graph for FILE. - ~C-u -N~ build the graph for FILE limiting nodes to N steps. - User Option: org-roam-graph-executable Path to the graphing executable (in this case, Graphviz). Set this if Org-roam is unable to find the Graphviz executable on your system. You may also choose to use ~neato~ in place of ~dot~, which generates a more compact graph layout. - User Option: org-roam-graph-viewer Org-roam defaults to using Firefox (located on PATH) to view the SVG, but you may choose to set it to: 1. A string, which is a path to the program used 2. a function accepting a single argument: the graph file path. ~nil~ uses ~view-file~ to view the graph. If you are using WSL2 and would like to open the graph in Windows, you can use the second option to set the browser and network file path: #+BEGIN_SRC emacs-lisp (setq org-roam-graph-viewer (lambda (file) (let ((org-roam-graph-viewer "/mnt/c/Program Files/Mozilla Firefox/firefox.exe")) (org-roam-graph--open (concat "file://///wsl$/Ubuntu" file))))) #+END_SRC ** Graph Options Graphviz provides many options for customizing the graph output, and Org-roam supports some of them. See https://graphviz.gitlab.io/_pages/doc/info/attrs.html for customizable options. - User Option: org-roam-graph-extra-config Extra options passed to graphviz for the digraph (The "G" attributes). Example: ~'~(("rankdir" . "LR"))~ - User Option: org-roam-graph-node-extra-config Extra options for nodes in the graphviz output (The "N" attributes). Example: ~'(("color" . "skyblue"))~ - User Option: org-roam-graph-edge-extra-config Extra options for edges in the graphviz output (The "E" attributes). Example: ~'(("dir" . "back"))~ - User Option: org-roam-graph-edge-cites-extra-config Extra options for citation edges in the graphviz output. Example: ~'(("color" . "red"))~ ** Excluding Nodes and Edges One may want to exclude certain files to declutter the graph. - User Option: org-roam-graph-exclude-matcher Matcher for excluding nodes from the generated graph. Any nodes and links for file paths matching this string is excluded from the graph. If value is a string, the string is the only matcher. If value is a list, all file paths matching any of the strings are excluded. #+BEGIN_EXAMPLE (setq org-roam-graph-exclude-matcher '("private" "dailies")) #+END_EXAMPLE This setting excludes all files whose path contain "private" or "dailies". * Minibuffer Completion Org-roam allows customization of which minibuffer completion system to use for its interactive commands. The default setting uses Emacs' standard ~completing-read~ mechanism. #+BEGIN_SRC emacs-lisp (setq org-roam-completion-system 'default) #+END_SRC If you have installed Helm or Ivy, and have their modes enabled, under the ~'default~ setting they will be used. In the rare scenario where you use Ivy globally, but prefer [[https://emacs-helm.github.io/helm/][Helm]] for org-roam commands, set: #+BEGIN_SRC emacs-lisp (setq org-roam-completion-system 'helm) #+END_SRC Other options include ~'ido~, and ~'ivy~. * Roam Protocol Org-roam extends ~org-protocol~ with 2 protocols: the ~roam-file~ and ~roam-ref~ protocols. ** Installation To enable Org-roam's protocol extensions, you have to add the following to your init file: #+BEGIN_SRC emacs-lisp (require 'org-roam-protocol) #+END_SRC The instructions for setting up ~org-protocol~ are reproduced below. We will also need to create a desktop application for ~emacsclient~. The instructions for various platforms are shown below. For Linux users, create a desktop application in ~~/.local/share/applications/org-protocol.desktop~: #+begin_example [Desktop Entry] Name=Org-Protocol Exec=emacsclient %u Icon=emacs-icon Type=Application Terminal=false MimeType=x-scheme-handler/org-protocol #+end_example Associate ~org-protocol://~ links with the desktop application by running in your shell: #+BEGIN_SRC bash xdg-mime default org-protocol.desktop x-scheme-handler/org-protocol #+END_SRC To disable the "confirm" prompt in Chrome, you can also make Chrome show a checkbox to tick, so that the ~Org-Protocol Client~ app will be used without confirmation. To do this, run in a shell: #+BEGIN_SRC bash sudo mkdir -p /etc/opt/chrome/policies/managed/ sudo tee /etc/opt/chrome/policies/managed/external_protocol_dialog.json >/dev/null <<'EOF' { "ExternalProtocolDialogShowAlwaysOpenCheckbox": true } EOF sudo chmod 644 /etc/opt/chrome/policies/managed/external_protocol_dialog.json #+END_SRC and then restart Chrome (for example, by navigating to ) to make the new policy take effect. See [[https://www.chromium.org/administrators/linux-quick-start][here]] for more info on the ~/etc/opt/chrome/policies/managed~ directory and [[https://cloud.google.com/docs/chrome-enterprise/policies/?policy=ExternalProtocolDialogShowAlwaysOpenCheckbox][here]] for information on the ~ExternalProtocolDialogShowAlwaysOpenCheckbox~ policy. For MacOS, we need to create our own application. 1. Launch Script Editor 2. Use the following script, paying attention to the path to ~emacsclient~: #+begin_src emacs-lisp on open location this_URL set EC to "/usr/local/bin/emacsclient --no-wait " set filePath to quoted form of this_URL do shell script EC & filePath tell application "Emacs" to activate end open location #+end_src 3. Save the script in ~/Applications/OrgProtocolClient.app~, changing the script type to "Application", rather than "Script". 4. Edit ~/Applications/OrgProtocolClient.app/Contents/Info.plist~, adding the following before the last ~~ tag: #+begin_src text CFBundleURLTypes CFBundleURLName org-protocol handler CFBundleURLSchemes org-protocol #+end_src 5. Save the file, and run the ~OrgProtocolClient.app~ to register the protocol. To disable the "confirm" prompt in Chrome, you can also make Chrome show a checkbox to tick, so that the ~OrgProtocol~ app will be used without confirmation. To do this, run in a shell: #+BEGIN_SRC bash defaults write com.google.Chrome ExternalProtocolDialogShowAlwaysOpenCheckbox -bool true #+END_SRC If you're using [[https://github.com/railwaycat/homebrew-emacsmacport][Emacs Mac Port]], it registered its `Emacs.app` as the default handler for the URL scheme `org-protocol`. To make ~OrgProtocol.app~ the default handler instead, run: #+BEGIN_SRC bash defaults write com.apple.LaunchServices/com.apple.launchservices.secure LSHandlers -array-add \ '{"LSHandlerPreferredVersions" = { "LSHandlerRoleAll" = "-"; }; LSHandlerRoleAll = "org.yourusername.OrgProtocol"; LSHandlerURLScheme = "org-protocol";}' #+END_SRC Then restart your computer. For Windows, create a temporary ~org-protocol.reg~ file: #+BEGIN_SRC text REGEDIT4 [HKEY_CLASSES_ROOT\org-protocol] @="URL:Org Protocol" "URL Protocol"="" [HKEY_CLASSES_ROOT\org-protocol\shell] [HKEY_CLASSES_ROOT\org-protocol\shell\open] [HKEY_CLASSES_ROOT\org-protocol\shell\open\command] @="\"C:\\Windows\\System32\\wsl.exe\" emacsclient \"%1\"" #+END_SRC The above will forward the protocol to WSL. If you run Emacs natively on Windows, replace the last line with: #+BEGIN_SRC text @="\"c:\\path\\to\\emacs\\bin\\emacsclientw.exe\" \"%1\"" #+END_SRC After executing the .reg file, the protocol is registered and you can delete the file. ** The roam-file protocol This is a simple protocol that opens the path specified by the ~file~ key (e.g. ~org-protocol://roam-file?file=/tmp/file.org~). This is used in the generated graph. ** The roam-ref protocol This protocol finds or creates a new note with a given ~roam_key~: [[file:images/roam-ref.gif]] To use this, create the following [[https://en.wikipedia.org/wiki/Bookmarklet][bookmarklet]] in your browser: #+BEGIN_SRC javascript javascript:location.href = 'org-protocol://roam-ref?template=r&ref=' + encodeURIComponent(location.href) + '&title=' + encodeURIComponent(document.title) + '&body=' + encodeURIComponent(window.getSelection()) #+END_SRC or as a keybinding in ~qutebrowser~ in , using the ~config.py~ file (see [[https://github.com/qutebrowser/qutebrowser/blob/master/doc/help/configuring.asciidoc][Configuring qutebrowser]]): #+BEGIN_SRC python config.bind("", "open javascript:location.href='org-protocol://roam-ref?template=r&ref='+encodeURIComponent(location.href)+'&title='+encodeURIComponent(document.title)") #+END_SRC where ~template~ is the template key for a template in ~org-roam-capture-ref-templates~ (see [[*The Templating System][The Templating System]]). These templates should contain a ~#+roam_key: ${ref}~ in it. * Daily-notes Org-roam provides journaling capabilities akin to [[#org-journal][Org-journal]] with ~org-roam-dailies~. ** Configuration For ~org-roam-dailies~ to work, you need to define two variables: - Variable: ~org-roam-dailies-directory~ Path to daily-notes. - Variable: ~org-roam-dailies-capture-templates~ Capture templates for daily-notes in Org-roam. Here is a sane default configuration: #+begin_src emacs-lisp (setq org-roam-dailies-directory "daily/") (setq org-roam-dailies-capture-templates '(("d" "default" entry #'org-roam-capture--get-point "* %?" :file-name "daily/%<%Y-%m-%d>" :head "#+title: %<%Y-%m-%d>\n\n"))) #+end_src Make sure that ~org-roam-dailies-directory~ appears in ~:file-name~ for your notes to be recognized as daily-notes. You can have different templates placing their notes in different directories, but the one in ~org-roam-dailies-directory~ will be considered as the main one in commands. See [[*The Templating System][The Templating System]] for creating new templates. ~org-roam-dailies~ provides an extra ~:olp~ option which allows specifying the outline-path to a heading: #+begin_src emacs-lisp (setq org-roam-dailies-capture-templates '(("l" "lab" entry #'org-roam-capture--get-point "* %?" :file-name "daily/%<%Y-%m-%d>" :head "#+title: %<%Y-%m-%d>\n" :olp ("Lab notes")) ("j" "journal" entry #'org-roam-capture--get-point "* %?" :file-name "daily/%<%Y-%m-%d>" :head "#+title: %<%Y-%m-%d>\n" :olp ("Journal")))) #+end_src The template ~l~ will put its notes under the heading ‘Lab notes’, and the template ~j~ will put its notes under the heading ‘Journal’. ** Capturing and finding daily-notes - Function: ~org-roam-dailies-capture-today~ &optional goto Create an entry in the daily note for today. When ~goto~ is non-nil, go the note without creating an entry. - Function: ~org-roam-dailies-find-today~ Find the daily note for today, creating it if necessary. There are variants of those commands for ~-yesterday~ and ~-tomorrow~: - Function: ~org-roam-dailies-capture-yesterday~ n &optional goto Create an entry in the daily note for yesteday. With numeric argument ~n~, use the daily note ~n~ days in the past. - Function: ~org-roam-dailies-find-yesterday~ With numeric argument N, use the daily-note N days in the future. There are also commands which allow you to use Emacs’s ~calendar~ to find the date - Function: ~org-roam-dailies-capture-date~ Create an entry in the daily note for a date using the calendar. Prefer past dates, unless ~prefer-future~ is non-nil. With a 'C-u' prefix or when ~goto~ is non-nil, go the note without creating an entry. - Function: ~org-roam-dailies-find-date~ Find the daily note for a date using the calendar, creating it if necessary. Prefer past dates, unless ~prefer-future~ is non-nil. ** Navigation You can navigate between daily-notes: - Function: ~org-roam-dailies-find-directory~ Find and open ~org-roam-dailies-directory~. - Function: ~org-roam-dailies-find-previous-note~ When in an daily-note, find the previous one. - Function: ~org-roam-dailies-find-next-note~ When in an daily-note, find the next one. * Diagnosing and Repairing Files Org-roam provides a utility for diagnosing and repairing problematic files via ~org-roam-doctor~. By default, ~org-roam-doctor~ runs the check on the current Org-roam file. To run the check only for all Org-roam files, run ~C-u M-x org-roam-doctor~, but note that this may take some time. - Function: org-roam-doctor &optional this-buffer Perform a check on Org-roam files to ensure cleanliness. If THIS-BUFFER, run the check only for the current buffer. The checks run are defined in ~org-roam-doctor--checkers~. By default, there are checkers for broken links and invalid =#+roam_*= properties. Each checker is an instance of ~org-roam-doctor-checker~. To define a checker, use ~make-org-roam-doctor-checker~. Here is a sample definition: #+BEGIN_SRC emacs-lisp (make-org-roam-doctor-checker :name 'org-roam-doctor-broken-links :description "Fix broken links." :actions '(("d" . ("Unlink" . org-roam-doctor--remove-link)) ("r" . ("Replace link" . org-roam-doctor--replace-link)) ("R" . ("Replace link (keep label)" . org-roam-doctor--replace-link-keep-label)))) #+END_SRC The ~:name~ property is the name of the function run. The function takes in the Org parse tree, and returns a list of ~(point error-message)~. ~:description~ is a short description of what the checker does. ~:actions~ is an alist containing elements of the form ~(char . (prompt . function))~. These actions are defined per checker, to perform autofixes for the errors. For each error detected, ~org-roam-doctor~ will move the point to the current error, and pop-up a help window displaying the error message, as well as the list of actions that can be taken provided in ~:actions~. * Finding Unlinked References Unlinked references are occurrences of strings of text that exactly match the title or alias of an existing note in the Org-roam database. Org-roam provides facilities for discovering these unlinked references, so one may decide whether to convert them into links. To use this feature, simply call ~M-x org-roam-unlinked-references~ from within an Org-roam note. Internally, Org-roam uses [[https://github.com/BurntSushi/ripgrep][ripgrep]] and a clever PCRE regex to find occurrences of the title or aliases of the currently open note in all Org-roam files. Hence, this requires a version of ripgrep that is compiled with PCRE support. #+begin_quote NOTE: Since ripgrep cannot read encrypted files, this function cannot find unlinked references within encrypted files. #+end_quote * Performance Optimization ** TODO Profiling Key Operations ** Garbage Collection During the cache-build process, Org-roam generates a lot of in-memory data-structures (such as the Org file's AST), which are discarded after use. These structures are garbage collected at regular intervals (see [[info:elisp#Garbage Collection][info:elisp#Garbage Collection]]). Org-roam provides the option ~org-roam-db-gc-threshold~ to temporarily change the threshold value for GC to be triggered during these memory-intensive operations. To reduce the number of garbage collection processes, one may set ~org-roam-db-gc-threshold~ to a high value (such as ~most-positive-fixnum~): #+BEGIN_SRC emacs-lisp (setq org-roam-db-gc-threshold most-positive-fixnum) #+END_SRC * _ Copying :PROPERTIES: :COPYING: t :END: #+BEGIN_QUOTE Copyright (C) 2020-2020 Jethro Kuan You can redistribute this document and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

It is included with GNU Emacs since version 20. ~winner-mode~ can be used as a simple version of browser history for Org-roam. Each click through org-roam links (from both Org files and the backlinks buffer) causes changes in window configuration, which can be undone and redone using ~winner-mode~. To use ~winner-mode~, simply enable it, and bind the appropriate interactive functions: #+BEGIN_SRC emacs-lisp (winner-mode +1) (define-key winner-mode-map (kbd "") #'winner-undo) (define-key winner-mode-map (kbd "") #'winner-redo) #+END_SRC *** Versioning Notes Since Org-roam notes are just plain text, it is trivial to track changes in your notes database using version control systems such as [[https://git-scm.com/][Git]]. Simply initialize ~org-roam-directory~ as a Git repository, and commit your files at regular or appropriate intervals. [[https://magit.vc/][Magit]] is a great interface to Git within Emacs. In addition, it may be useful to observe how a particular note has evolved, by looking at the file history. [[https://gitlab.com/pidu/git-timemachine][Git-timemachine]] allows you to visit historic versions of a tracked Org-roam note. *** Full-text search interface with Deft :PROPERTIES: :CUSTOM_ID: deft :END: [[https://jblevins.org/projects/deft/][Deft]] provides a nice interface for browsing and filtering org-roam notes. #+BEGIN_SRC emacs-lisp (use-package deft :after org :bind ("C-c n d" . deft) :custom (deft-recursive t) (deft-use-filter-string-for-filename t) (deft-default-extension "org") (deft-directory "/path/to/org-roam-files/")) #+END_SRC If the title of the Org file is not the first line, you might not get nice titles. You may choose to patch this to use ~org-roam~'s functionality. Here I'm using [[https://github.com/raxod502/el-patch][el-patch]]: #+BEGIN_SRC emacs-lisp (use-package el-patch :straight (:host github :repo "raxod502/el-patch" :branch "develop")) (eval-when-compile (require 'el-patch)) #+END_SRC The Deft interface can slow down quickly when the number of files get huge. [[https://github.com/hasu/notdeft][Notdeft]] is a fork of Deft that uses an external search engine and indexer. *** Org-journal :PROPERTIES: :CUSTOM_ID: org-journal :END: [[https://github.com/bastibe/org-journal][Org-journal]] provides journaling capabilities to Org-mode. A lot of its functionalities have been incorporated into Org-roam under the name [[*Daily-notes][~org-roam-dailies~]]. It remains a good tool if you want to isolate your verbose journal entries from the ideas you would write on a scratchpad. #+BEGIN_SRC emacs-lisp (use-package org-journal :bind ("C-c n j" . org-journal-new-entry) :custom (org-journal-date-prefix "#+title: ") (org-journal-file-format "%Y-%m-%d.org") (org-journal-dir "/path/to/journal/files/") (org-journal-date-format "%A, %d %B %Y")) #+END_SRC *** Note-taking Add-ons :PROPERTIES: :CUSTOM_ID: note-taking-add-ons :END: These are some plugins that make note-taking in Org-mode more enjoyable. **** Org-download :PROPERTIES: :CUSTOM_ID: org-download :END: [[https://github.com/abo-abo/org-download][Org-download]] lets you screenshot and yank images from the web into your notes: #+CAPTION: org-download [[file:images/org-download.gif]] #+BEGIN_SRC emacs-lisp (use-package org-download :after org :bind (:map org-mode-map (("s-Y" . org-download-screenshot) ("s-y" . org-download-yank)))) #+END_SRC **** mathpix.el :PROPERTIES: :CUSTOM_ID: mathpix.el :END: [[https://github.com/jethrokuan/mathpix.el][mathpix.el]] uses [[https://mathpix.com/][Mathpix's]] API to convert clips into latex equations: #+CAPTION: mathpix [[file:images/mathpix.gif]] #+BEGIN_SRC emacs-lisp (use-package mathpix.el :straight (:host github :repo "jethrokuan/mathpix.el") :custom ((mathpix-app-id "app-id") (mathpix-app-key "app-key")) :bind ("C-x m" . mathpix-screenshot)) #+END_SRC **** Org-noter / Interleave :PROPERTIES: :CUSTOM_ID: org-noter-interleave :END: [[https://github.com/weirdNox/org-noter][Org-noter]] and [[https://github.com/rudolfochrist/interleave][Interleave]] are both projects that allow synchronised annotation of documents (PDF, EPUB etc.) within Org-mode. **** Bibliography :PROPERTIES: :CUSTOM_ID: bibliography :END: [[https://github.com/org-roam/org-roam-bibtex][org-roam-bibtex]] offers tight integration between [[https://github.com/jkitchin/org-ref][org-ref]], [[https://github.com/tmalsburg/helm-bibtex][helm-bibtex]] and ~org-roam~. This helps you manage your bibliographic notes under ~org-roam~. For example, though helm-bibtex provides the ability to visit notes for bibliographic entries, org-roam-bibtex extends it with the ability to visit the file with the right =#+roam_key=. **** Spaced Repetition :PROPERTIES: :CUSTOM_ID: spaced-repetition :END: [[https://www.leonrische.me/fc/index.html][Org-fc]] is a spaced repetition system that scales well with a large number of files. Other alternatives include [[https://orgmode.org/worg/org-contrib/org-drill.html][org-drill]], and [[https://github.com/abo-abo/pamparam][pamparam]]. * FAQ ** How do I have more than one Org-roam directory? Emacs supports directory-local variables, allowing the value of ~org-roam-directory~ to be different in different directories. It does this by checking for a file named ~.dir-locals.el~. To add support for multiple directories, override the ~org-roam-directory~ variable using directory-local variables. This is what ~.dir-locals.el~ may contain: #+BEGIN_SRC emacs-lisp ((nil . ((org-roam-directory . ".") (org-roam-db-location . "./org-roam.db")))) #+END_SRC All files within that directory will be treated as their own separate set of Org-roam files. Remember to run ~org-roam-db-build-cache~ from a file within that directory, at least once. ** How do I migrate from Roam Research? Fabio has produced a command-line tool that converts markdown files exported from Roam Research into Org-roam compatible markdown. More instructions are provided [[https://github.com/fabioberger/roam-migration][in the repository]]. ** How do I create a note whose title already matches one of the candidates? This situation arises when, for example, one would like to create a note titled "bar" when "barricade" already exists. The solution is dependent on the mini-buffer completion framework in use. Here are the solutions: - Ivy :: call ~ivy-immediate-done~, typically bound to ~C-M-j~. Alternatively, set ~ivy-use-selectable-prompt~ to ~t~, so that "bar" is now selectable. - Helm :: Org-roam should provide a selectable "[?] bar" candidate at the top of the candidate list. * Keystroke Index :PROPERTIES: :APPENDIX: t :INDEX: ky :COOKIE_DATA: recursive :END: * Command Index :PROPERTIES: :APPENDIX: t :INDEX: cp :END: * Function Index :PROPERTIES: :APPENDIX: t :INDEX: fn :END: * Variable Index :PROPERTIES: :APPENDIX: t :INDEX: vr :END: * Footnotes [fn:1] Depending on your completion framework, you may need to press TAB to see the list.
