# Changelog
## 2.2.1
### Breaking
- [#2054](https://github.com/org-roam/org-roam/pull/2054) node: simplify default `org-roam-node-display-template`.
This was done so completions work fine by default on all completion systems. To restore the tabular vertical completion interface, set this in your configuration:
```emacs-lisp
(setq org-roam-node-display-template
(concat "${title:*} "
(propertize "${tags:10}" 'face 'org-tag)))
```
## 1.2.4 (TBD)

## Installation
Down below you will find basic installation instructions for how to quickly
install `org-roam` using various environments for various purposes. For more
detailed information, please read the [manual][docs].
### Using `package.el`
<details>
<summary>Toggle instructions</summary>
You can install `org-roam` from [MELPA](https://melpa.org/) or [MELPA
Stable](https://stable.melpa.org/) using `package.el`:
You can install `org-roam` using `package.el`:
```
M-x package-install RET org-roam RET
```
</details>
### Using `straight.el`
<details>
<summary>Toggle instructions</summary>
Installation from MELPA or MELPA Stable using `straight.el`:
```emacs-lisp
(straight-use-package 'org-roam)
```
Or with `use-package`:
Here's a sample configuration with `use-package`:
```emacs-lisp
(use-package org-roam
:straight t
...)
:ensure t
:custom
(org-roam-directory (file-truename "/path/to/org-files/"))
:bind (("C-c n l" . org-roam-buffer-toggle)
("C-c n f" . org-roam-node-find)
("C-c n g" . org-roam-graph)
("C-c n i" . org-roam-node-insert)
("C-c n c" . org-roam-capture)
;; Dailies
("C-c n j" . org-roam-dailies-capture-today))
:config
(org-roam-setup)
;; If using org-roam-protocol
(require 'org-roam-protocol))
```
If you need to install the package directly from the source repository, instead
of from MELPA, the next sample shows how to do so:
The `file-truename` function is only necessary when you use symbolic links
inside `org-roam-directory`: Org-roam does not resolve symbolic links.
```emacs-lisp
(use-package org-roam
:straight (:host github :repo "org-roam/org-roam"
:files (:defaults "extensions/*"))
...)
```
If you plan to use your own local fork for the development and contribution, the
next sample will get you there:
```emacs-lisp
(use-package org-roam
:straight (:local-repo "/path/to/org-roam-fork"
:files (:defaults "extensions/*")
:build (:not compile))
...)
```
</details>
### Using Doom Emacs
<details>
<summary>Toggle instructions</summary>
Doom's `:lang org` module comes with support for `org-roam`, but it's not
enabled by default. To activate it pass `+roam2` flag to `org` module in your
`$DOOMDIR/init.el` (e.g. `(org +roam2)`), save the file and run `doom sync -u`
in your shell.
To provide better stability, Doom pins the package to a specific commit. If you
need to unpin it *(not recommended doing that, request Doom to bump the package
instead)* use the next in your `packages.el`:
```emacs-lisp
(unpin! org-roam)
```
If for some reasons you want to use a different recipe for `org-roam`, you can
use the next form in your `packages.el` to install the package from a recipe
repository (e.g. MELPA):
```emacs-lisp
(package! org-roam)
```
You can pass `:pin "commit hash"` to pin the package to a specific commit.
With the next sample you can install the package directly from the source
repository:
```emacs-lisp
(package! org-roam
:recipe (:host github :repo "org-roam/org-roam"
:files (:defaults "extensions/*")))
```
And if you plan to use your own local fork for the development or contribution,
the next sample will get you there:
```emacs-lisp
(package! org-roam
:recipe (:local-repo "/path/to/org-roam-fork"
:files (:defaults "extensions/*")
:build (:not compile)))
```
</details>
### Without a package manager
<details>
<summary>Toggle instructions</summary>
To install the package without using a package manager you have the next two
options:
1. Install the package by cloning it with `git` from the source repository.
2. Or install the package by downloading the latest [release
version](https://github.com/org-roam/org-roam/releases).
In both of the cases you will need to ensure that you have all the required
dependencies. These include:
- dash
- f
- s
- org (9.4 is the minimal required version!)
- emacsql
- emacsql-sqlite
- magit-section
- filenotify-recursive
After installing the package, you will need to properly setup `load-path` to the
package:
``` emacs-lisp
(add-to-list 'load-path "/path/to/org-roam/")
(add-to-list 'load-path "/path/to-org-roam/extensions/")
```
After which you should be able to resolve `(require 'org-roam)` call without any
problems.
Org-roam also comes with `.texi` files to integrate with Emacs' built-in Info
system. Read the manual to find more details for how to install them manually.
</details>
## Configuration
Here's a very basic sample for configuration of `org-roam` using `use-package`:
```emacs-lisp
(use-package org-roam
:ensure t
:custom
(org-roam-directory (file-truename "/path/to/org-files/"))
:bind (("C-c n l" . org-roam-buffer-toggle)
("C-c n f" . org-roam-node-find)
("C-c n g" . org-roam-graph)
("C-c n i" . org-roam-node-insert)
("C-c n c" . org-roam-capture)
;; Dailies
("C-c n j" . org-roam-dailies-capture-today))
:config
;; If you're using a vertical completion framework, you might want a more informative completion interface
(setq org-roam-node-display-template (concat "${title:*} " (propertize "${tags:10}" 'face 'org-tag)))
(org-roam-db-autosync-mode)
;; If using org-roam-protocol
(require 'org-roam-protocol))
```
Note that the `file-truename` function is only necessary when you use symbolic
link to `org-roam-directory`. Org-roam won't automatically resolve symbolic link
to the directory.
## Getting Started
[David Wilson](https://github.com/daviwil) of [System
Crafters](https://www.youtube.com/c/SystemCrafters) has produced an introductory
video that covers the basic commands:
[![Getting Started with Org Roam - Build a Second Brain in Emacs](https://img.youtube.com/vi/AyhPmypHDEw/0.jpg)](https://www.youtube.com/watch?v=AyhPmypHDEw)
Org-roam requires sqlite to function. Org-roam optionally uses Graphviz for
graph-related functionality. It is recommended to install PCRE-enabled ripgrep
for better performance and extended functionality.

- For Windows:
One of the easiest ways to install a C compiler in Windows is to use [[https://www.msys2.org/][MSYS2]] as at the time of this writing:
There are various ways to install one, depending on how you have installed
Emacs. If you use Emacs within a Cygwin or MinGW environment, then you should
install a compiler using their respective package manager.

1. Use the installer in the official website and install MSYS2
2. Run MSYS2
3. In the command-line tool, type the following and answer "Y" to proceed:

4. On Windows, add ~C:\msys64\usr\bin~ (command =where gcc= in MSYS2 terminal
can tell you the correct path) to ~PATH~ in your environmental variables
Note that you do not need to manually set the PATH for MSYS2; the
installer automatically takes care of it for you.
5. Launch Emacs and call ~M-x org-roam-db-autosync-mode~ (launch Emacs after
defining the path, so that Emacs can recognize it)

** Creating and Linking Nodes
** Customizing Node Caching
By default, all nodes (any headline or file with an ID) are cached by Org-roam.
There are instances where you may want to have headlines with ID, but not have
them cached by Org-roam.
To exclude a headline from the Org-roam database, set the ~ROAM_EXCLUDE~
property to a non-nil value. For example:
#+begin_src org
,* Foo
:PROPERTIES:
:ID: foo
:ROAM_EXCLUDE: t
:END:
#+end_src
One can also set ~org-roam-db-node-include-function~. For example, to exclude
all headlines with the ~ATTACH~ tag from the Org-roam database, one can set:
#+begin_src org
(setq org-roam-db-node-include-function
(lambda ()
(not (member "ATTACH" (org-get-tags)))))

brought through the node creation process.
One can also conveniently insert links via the completion-at-point functions
Org-roam provides (see [[*Completion][Completion]]).
** Customizing Node Completions
Node selection is achieved via the ~completing-read~ interface, typically
through `org-roam-node-read`. The presentation of these nodes are governed by
~org-roam-node-display-template~.
- Variable: org-roam-node-display-template
Configures display formatting for Org-roam node.
Patterns of form "${field-name:length}" are interpolated based
on the current node.
Each "field-name" is replaced with the return value of each
corresponding accessor function for org-roam-node, e.g.
"${title}" will be interpolated by the result of
org-roam-node-title. You can also define custom accessors using
cl-defmethod. For example, you can define:
(cl-defmethod org-roam-node-my-title ((node org-roam-node))
(concat "My " (org-roam-node-title node)))
and then reference it here or in the capture templates as
"${my-title}".
"length" is an optional specifier and declares how many
characters can be used to display the value of the corresponding
field. If it's not specified, the field will be inserted as is,
i.e. it won't be aligned nor trimmed. If it's an integer, the
field will be aligned accordingly and all the exceeding
characters will be trimmed out. If it's "*", the field will use
as many characters as possible and will be aligned accordingly.
A closure can also be assigned to this variable in which case the
closure is evaluated and the return value is used as the
template. The closure must evaluate to a valid template string.
If you're using a vertical completion framework, such as Ivy and Selectrum,
Org-roam supports the generation of an aligned, tabular completion interface.
For example, to include a column for tags up to 10 character widths wide, one
can set ~org-roam-node-display-template~ as such:
#+begin_src emacs-lisp
(setq org-roam-node-display-template
(concat "${title:*} "
(propertize "${tags:10}" 'face 'org-tag)))

* Customizing Node Caching
** How to cache
:PROPERTIES:
:ID: 280bfca8-83f3-4371-bc3a-25478d25129c
:END:
Org-roam uses a sqlite database to perform caching, but there are multiple Emacs
libraries that can be used. The default used by Org-roam is ~emacs-sqlite~.
Below the pros and cons of each package is used:
[[https://github.com/skeeto/emacsql][**emacs-sqlite**]]
The default option used by Org-roam. This library is the most mature and
well-supported and is imported by default in Org-roam.
One downside of using ~emacs-sqlite~ is that using it requires compilation and
can cause issues in some environments (especially Windows). If you have issues
producing the customized binary required by ~emacs-sqlite~, consider using
~emacs-sqlite3~.
[[https://github.com/cireu/emacsql-sqlite3][**emacs-sqlite3**]]
~emacs-sqlite3~ uses the official sqlite3 binary that can be obtained from your
system's package manager. This is useful if you have issues producing the
~sqlite3~ binary required by the other packages. However, it is not recommended
because it has some compatibility issues with Emacs, but should work for most
regular cases. See [[https://nullprogram.com/blog/2014/02/06/][Chris Wellon's blog post]] for more information.
To use ~emacsql-sqlite3~, ensure that the package is installed, and set:
#+begin_src emacs-lisp
(setq org-roam-database-connector 'sqlite3)
#+end_src
[[https://github.com/emacscollective/emacsql-libsqlite3/][**emacsql-libsqlite3**]]
~emacs-libsqlite3~ is a relatively young package which uses an Emacs module that
exposes parts of the SQLite C API to Emacs Lisp, instead of using subprocess as
~emacsql-sqlite~ does. It is expected to be a more performant drop-in
replacement for ~emacs-sqlite~.
At the moment it is experimental and does not work well with the SQL query load
required by Org-roam, but you may still try it by ensuring the package is
installed and setting:
#+begin_src emacs-lisp
(setq org-roam-database-connector 'libsqlite3)
#+end_src
** What to cache
By default, all nodes (any headline or file with an ID) are cached by Org-roam.
There are instances where you may want to have headlines with ID, but not have
them cached by Org-roam.
To exclude a headline from the Org-roam database, set the ~ROAM_EXCLUDE~
property to a non-nil value. For example:
#+begin_src org
,* Foo
:PROPERTIES:
:ID: foo
:ROAM_EXCLUDE: t
:END:
#+end_src
One can also set ~org-roam-db-node-include-function~. For example, to exclude
all headlines with the ~ATTACH~ tag from the Org-roam database, one can set:
#+begin_src org
(setq org-roam-db-node-include-function
(lambda ()
(not (member "ATTACH" (org-get-tags)))))
#+end_src
Org-roam relied on the obtained Org AST for the buffer to parse links. However,
links appearing in some places (e.g. within property drawers) are not considered
by the Org AST to be links. Therefore, Org-roam takes special care of
additionally trying to process these links. Use
~org-roam-db-extra-links-elements~ to specify which additional Org AST element
types to consider.
- Variable: org-roam-db-extra-links-elements
The list of Org element types to include for parsing by Org-roam.
By default, when parsing Org's AST, links within keywords and
property drawers are not parsed as links. Sometimes however, it
is desirable to parse and cache these links (e.g. hiding links in
a property drawer).
Additionally, one may want to ignore certain keys from being excluded within
property drawers. For example, we would not want ~ROAM_REFS~ links to be
self-referential. Hence, to exclude specific keys, we use
~org-roam-db-extra-links-exclude-keys~.
- Variable: org-roam-db-extra-links-exclude-keys
Keys to ignore when mapping over links.
The car of the association list is the Org element type (e.g. keyword). The
cdr is a list of case-insensitive strings to exclude from being treated as
links.
** When to cache
By default, Org-roam is eager in caching: each time an Org-roam file is modified
and saved, it updates the database for the corresponding file. This keeps the
database up-to-date, causing the least surprise when using the interactive
commands.
However, depending on how large your Org files are, database updating can be a
slow operation. You can disable the automatic updating of the database by
setting ~org-roam-db-update-on-save~ to ~nil~.
- Variable: org-roam-db-update-on-save
If t, update the Org-roam database upon saving the file. Disable this if your
files are large and updating the database is slow.

* The Org-roam Buffer

other notes (backlinks, reference links, unlinked references etc.). There are
two main commands to use here:

* Citations
Since version 9.5, Org has first-class support for citations. Org-roam supports
the caching of both these in-built citations (of form ~[cite:@key]~) and [[https://github.com/jkitchin/org-ref][org-ref]]
citations (of form cite:key).
Org-roam attempts to load both the ~org-ref~ and ~org-cite~ package when
indexing files, so no further setup from the user is required for citation
support.
** Using the Cached Information
It is common to use take reference notes for academic papers. To designate the
node to be the canonical node for the academic paper, we can use its unique
citation key:
#+begin_src org

** How to migrate from Org-roam v1?
* Migrating from Org-roam v1
Those coming from Org-roam v1 will do well treating v2 as entirely new software.
V2 has a smaller core and fewer moving parts, while retaining the bulk of its
functionality. It is recommended to read the documentation above about nodes.
It is still desirable to migrate notes collected in v1 to v2.
To migrate your v1 notes to v2, use =M-x org-roam-migrate-wizard=.
[[https://d12frosted.io/posts/2021-06-11-path-to-org-roam-v2.html][This blog post]]
provides a good overview of what's new in v2 and how to migrate.
It is still desirable to migrate notes collected in v1 to v2. To migrate your v1
notes to v2, you may use the migration script provided in [[https://gist.github.com/jethrokuan/02f41028fb4a6f81787dc420fb99b6e4][this gist]], or [[https://gist.github.com/jethrokuan/02f41028fb4a6f81787dc420fb99b6e4#gistcomment-3737019][this
gist]], the latter being better tested. [[https://d12frosted.io/posts/2021-06-11-path-to-org-roam-v2.html][This blog post]] provides a good overview of
what's new in v2 and how to migrate.
Essentially, to migrate notes from v1 to v2, one must:
Simply put, to migrate notes from v1 to v2, one must:

1. Add IDs to all existing notes. These are located in top-level property
drawers (Although note that in v2, not all files need to have IDs)
2. Update the Org-roam database to conform to the new schema.
3. Replace ~#+ROAM_KEY~ into the ~ROAM_REFS~ property
4. Replace ~#+ROAM_ALIAS~ into the ~ROAM_ALIASES~ property
5. Move ~#+ROAM_TAGS~ into the ~#+FILETAGS~ property for file-level nodes,
and the ~ROAM_TAGS~ property for headline nodes
5. Move ~#+ROAM_TAGS~ into the ~#+FILETAGS~ property for file-level nodes, and
the ~ROAM_TAGS~ property for headline nodes
6. Replace existing file links with ID links.
** How do I publish my notes with an Internet-friendly graph?
The default graph builder creates a graph with an [[https://orgmode.org/worg/org-contrib/org-protocol.html][org-protocol]]
handler which is convenient when you're working locally but
inconvenient when you want to publish your notes for remote access.
Likewise, it defaults to displaying the graph in Emacs which has the
exact same caveats. This problem is solvable in the following way
using org-mode's native [[https://orgmode.org/manual/Publishing.html][publishing]] capability:
1. configure org-mode to publish your org-roam notes as a project.
2. create a function that overrides the default org-protocol link
creation function(=org-roam-default-link-builder=).
3. create a hook that's called at the end of graph creation to copy
the generated graph to the appropriate place.
The example code below is used to publish to a local directory where a
separate shell script copies the files to the remote site.
*** Configure org-mode for publishing
This has two steps:
1. Setting of a /roam/ project that publishes your notes.
2. Configuring the /sitemap.html/ generation.
3. Setting up =org-publish= to generate the graph.
This will require code like the following:
#+begin_src emacs-lisp
(defun roam-sitemap (title list)
(concat "#+OPTIONS: ^:nil author:nil html-postamble:nil\n"
"#+SETUPFILE: ./simple_inline.theme\n"
"#+TITLE: " title "\n\n"
(org-list-to-org list) "\nfile:sitemap.svg"))
(setq my-publish-time 0) ; see the next section for context
(defun roam-publication-wrapper (plist filename pubdir)
(org-roam-graph)
(org-html-publish-to-html plist filename pubdir)
(setq my-publish-time (cadr (current-time))))
(setq org-publish-project-alist
'(("roam"
:base-directory "~/roam"
:auto-sitemap t
:sitemap-function roam-sitemap
:sitemap-title "Roam notes"
:publishing-function roam-publication-wrapper
:publishing-directory "~/roam-export"
:section-number nil
:table-of-contents nil
:style "<link rel=\"stylesheet\" href=\"../other/mystyle.cs\" type=\"text/css\">")))
#+end_src
*** Overriding the default link creation function
The code below will generate a link to the generated html file instead
of the default org-protocol link.
#+begin_src emacs-lisp
(defun org-roam-custom-link-builder (node)
(let ((file (org-roam-node-file node)))
(concat (file-name-base file) ".html")))
(setq org-roam-graph-link-builder 'org-roam-custom-link-builder)
#+end_src
*** Copying the generated file to the export directory
The default behavior of =org-roam-graph= is to generate the graph and
display it in Emacs. There is an =org-roam-graph-generation-hook=
available that provides access to the file names so they can be copied
to the publishing directory. Example code follows:
#+begin_src emacs-lisp
(add-hook 'org-roam-graph-generation-hook
(lambda (dot svg) (if (< (- (cadr (current-time)) my-publish-time) 5)
(progn (copy-file svg "~/roam-export/sitemap.svg" 't)
(kill-buffer (file-name-nondirectory svg))
(setq my-publish-time 0)))))
#+end_src
** I'm seeing this "Selecting deleted buffer" error. What do I do?
The "selecting deleted buffer" error usually occurs when you don't have a
working ~emacsql-sqlite~ executable. Org-roam relies on this executable to
function properly, and doesn't catch this error. This issue is most commonly
seen on Windows setups. You can browse through the various GitHub issues posted
about this [[https://github.com/org-roam/org-roam/issues?q=is%3Aissue+selecting+deleted][here]].
To fix this, you can try the following:
1. If on Windows, try replacing your system binary with [[https://github.com/nobiot/emacsql-sqlite.exe][this one]] that has been proven
to work
2. Use the ~emacsql-sqlite3~ option rather than compiling your own emacsql
binary (see [[id:280bfca8-83f3-4371-bc3a-25478d25129c][How to cache]]).

(defvar org-roam-capture-preface-hook nil
"Hook run when Org-roam tries to determine capture location of the node.
If any hook returns a value (which should be an ID), all hooks
after it are ignored.
With this hook you can hijack controls over the location of the
node for which the capture process is currently running for, or
use to just perform an arbitrary side effect, e.g. modify the
state related to the capture process. See `org-roam-protocol' and
`org-roam-dailies' as examples for what and how this hook is used
for.
If you're trying to perform the hijack, it's mandatory for you to:
1. Set the currently active buffer for editing operations using
`org-capture-target-buffer'.
2. Place the point in this buffer from where the location starts
from (e.g. if it's a file based node it should be the BOB,
otherwise it should be the position from where the heading
based node starts from).
3. Return the ID (as a string) of the capturing node.
If you use this hook for any other purpose, but not the hijack,
it's mandatory that you should return nil as the return value; so
the capture process would be able to setup the capture buffer.
If you need to do something when you capture new nodes, use
`org-roam-capture-new-node-hook' instead of this hook.
WARNING: This hook is primarily designed for the usage by the
extensions and packages, and requires understanding of the
internal capture process. If you don't understand it, you should
learn these internals before using this or use it at your own
risk breaking things.")

package. This is still experimental. When `sqlite3', then use the
`emacsql-sqlite3' library, which uses the official `sqlite3' cli
tool, which is not recommended because it is not suitable to be
used like this, but has the advantage that you likely don't need
a compiler. See https://nullprogram.com/blog/2014/02/06/."

"The value to temporarily set the `gc-cons-threshold' threshold to.
During `org-roam-db-sync', Emacs can pause multiple times to
perform garbage collection because of the large number of
temporary structures generated (e.g. parsed ASTs).
During large, heavy operations like `org-roam-db-sync',
many GC operations happen because of the large number of
temporary structures generated (e.g. parsed ASTs). Temporarily
increasing `gc-cons-threshold' will help reduce the number of GC
operations, at the cost of temporary memory usage.
`gc-cons-threshold' is temporarily set to
`org-roam-db-gc-threshold' during this operation, and increasing
`gc-cons-threshold' will help reduce the number of GC operations,
at the cost of memory usage. Tweaking this value may lead to
better overall performance.
For example, to reduce the number of GCs to the minimum, on
machines with large memory one may set it to
`most-positive-fixnum'."
This defaults to the original value of `gc-cons-threshold', but
tweaking this number may lead to better overall performance. For
example, to reduce the number of GCs, one may set it to a large
value like `most-positive-fixnum'."

If you've gone through the migration steps (if necessary), and
know what you're doing set `org-roam-v2-ack' to `t' to disable
this warning. You can do so by adding:
(setq org-roam-v2-ack t)
