with the
default system application.
What is a personal wiki/ desktop wiki?
It is a digital notebook or a note taking app integrated with desktop. Some examples are Zim Wiki, Microsoft OneNote and Tomboy (software).
What org-wiki is not
- It is not a server wiki like Mediawiki (Wikipedia Engine) or Dokuwiki. So it has no administrative panel and user account and so on. Despite it not be a server wiki, it can serve org pages (*.org files) exported html with Python3 web server help in read-only mode.
Why org-wiki?
Server wikis are hard to manage and install for a single user and requires installation of a web server like Apache, PHP and a database server like MySql or PostgresSQL.
Desktop wikis like org-wiki, Zim, OneNote and Tomboy are easier to install and manage than server wikis and has less memory requirements.
The problems of many wikis are the lack of a good text editor, extensibility and desktop integration. Org-wiki solves that by putting the Wiki inside the most awesome text editor: Emacs and everything is just one keybinding or one command away. Another advantage is the org-mode format and Emacs integration that provides fast editing, fast refactoring, headline folding, fast table manipulation, export to many formats like html, pdf and so on, Latex equations and literate programming in many languages like C, C , Python, R and so on.
You can see Org-mode Screencasts and reviews here:
- (1) Browsing Index: M-x org-wiki/index
- (2) M-x org-wiki/helm - Select a wiki page by name.
- (3) M-x org-wiki/insert Insert a link to wiki page at cursor position.
- (4) - M-x org-wiki/asset-insert Insert a link to a asset file that when clicked opens it with default system application.
See video: M-x org-wiki/asset-insert
- (5) - Org-wiki exported to HTML
You can view a sample wiki exported to html here:
- Sample org-wiki exported to html
- This sample wiki is available at sandbox/wiki
- 1. Command
M-x org-wiki-index
Open the wiki index page (file index.org)
- 2. Command
M-x org-wiki-helm
Open a helm menu to select the wiki page to be opened.
- 3.
M-x org-wiki- [tab]
provides easy completion and discoverability to org-wiki commands.
- 4.
M-x org-wiki-dired
Open the org-wiki directory showing only the wiki pages (*.org files).
- 5.
M-x org-wiki-dired-all
Open the org-wiki directory showing all files.
- 6.
M-x org-wiki-search-pattern
Search for all wiki page that contains a pattern. (string or regex pattern).
Example: The command M-x org-wiki/search-patern - System.Windows
will search all
files that contains “System.Windows string”.
Now org wiki supports multiple wikis or root directories, but only one wiki can be used at a time. So, to switch wiki type:
M-x org-wiki-switch-root
To create a page do:
- 1. M-x org-wiki-index - It goes to the Org-wiki index page (index.org).
- 2. Then run
M-x org-wiki-insert-new
and a page name like ‘CNC - Computer Numerical Control’
It will insert a hyperlink at point like:
[[wiki:CNC - Computer Numerical Control][CNC - Computer Numerical Control]]
- 3. Then click at the link or enter C-x C-o at the link to open it.
Run M-x org-wiki-new
and enter the page name, for instance ‘Unix System Calls’,
it will create the file ‘Unix System Calls.org’ in the root directory
and open it for editing.
The advantage of creating a page using ‘way 1’ is that it inserts a link to the new created page before opening it, therefore making easier to categorize and navigate the pages.
The navigation can be done by running
M-x org-wiki-index
It will open the index page which contains hyperlinks to other wiki pages.
or
M-x org-wiki-helm
that will show a helm combobox menu where the user view all pages and search a page by typing its name.
or
M-x org-wiki-helm-frame
to open a page in another frame (Emacs terminology for GUI window).
Evaluate this code in the scratch buffer that will install all
dependencies and this package. The scratch buffer can be evaluated
with M-x eval-buffer
.
(let ((url "https://raw.githubusercontent.com/caiorss/org-wiki/master/org-wiki.el"))
(with-current-buffer (url-retrieve-synchronously url)
(goto-char (point-min))
(re-search-forward "^$")
(delete-region (point) (point-min))
(kill-whole-line)
(package-install-from-buffer)))
Just copy this piece of code to scratch buffer and eveluate the buffer
with M-x eval-buffer
. It is assumed that el-get is already installed.
(el-get-bundle org-wiki
:url "https://raw.githubusercontent.com/caiorss/org-wiki/master/org-wiki.el"
:description "Emacs' desktop wiki built with org-mode"
:features org-wiki
)
Copy the package to the desired location.
mkdir -p ~/.emacs.d/packages/
cd ~/.emacs.d/packages/
git clone https://github.com/caiorss/org-wiki
mkdir -p ~/org/wiki # Make wiki location.
Make org-wiki directory
M-x make-directory ~/org-wiki
Add to init file ~/.emacs.d/init.el or ~/.emacs
(require 'org-wiki)
Org-wiki can configured programatically by setting the org-wiki custom
varibles or with M-x customize-group org-wiki
.
This new version supports multiples org-wiki directories or multiple
wikis in different directories, but only one wiki can be used at a
time. The current wiki directory can be selected by using te command
M-x org-wiki-switch-root
.
Paths where all org-wiki pages (*.org files) are stored.
;;
;; (setq org-wiki-location "~/org/wiki")
(setq org-wiki-location-list
'(
"~/Documents/wiki" ;; First wiki (root directory) is the default.
"~/Documents/wiki2 "
"~/Documents/wiki3"
))
;; Initialize first org-wiki-directory or default org-wiki
(setq org-wiki-location (car org-wiki-location-list))
The default value of this variable is
'("~/org/wiki")
In Windows it can be:
- Note: backward slash in path \, must be escaped as
;; (setq org-wiki-location "e:/projects/org-wiki-test.emacs")
(setq org-wiki-location-list
'(
"C:\\Users\\john\\Documents\\wiki-main" ;; First wiki is the default.
"F:/storage/wiki2"
"G:\\Documents\\wiki3"
))
If the custom variable org-wiki-default-read-only
is set to true (t)
org-wiki pages are opened in read-only mode. The default value of this
variable is nil (false). It is useful to avoid unintended and
accidental changings an org-wiki page.
The read-only mode can be toggled with M-x toggle-read-only
or C-x C-q.
- Open org-wiki pages in read-only mode.
(setq org-wiki-default-read-only t)
- Open org-wiki pages in non read-only mode.
(setq org-wiki-default-read-only nil) ;; Default value
If the custom variable org-wiki-close-root-switch
(default value
true, t) is set to true, it will close all org-wiki pages of the
current wiki (root path) before switching to another org-wiki
location.
Enable:
(setq org-wiki-close-root-switch t)
Disable
(setq org-wiki-close-root-switch nil)
Org-wiki can serve the pages exported to html with python help.
The variable org-wiki-server-port (default value 8000) sets the default port that Python web server will listen to.
It can be set with:
(setq org-wiki-server-port "8000") ;; 8000 - default value
The variable org-wiki-server-host (default value 0.0.0.0 - all hosts) sets the host that the Python server will listen.
It can be set with:
(setq org-wiki-server-host "0.0.0.0") ;; Listen all hosts (default value)
(setq org-wiki-server-host "127.0.0.1") ;; Listen only localhost
In order to the html export work the path to emacs executable
directory must be in the $PATH variable. In some OS like Windows where
this path is not in $PATH variable it is necessary to set the variable
org-wiki-emacs-path
like:
(setq org-wiki-emacs-path "c:/Users/arch/opt/emacs/bin/runemacs.exe")
Optional: This package provides the command M-x org-wiki-make-menu
that installs a menu on the menu bar.
The menu can be installed permanently by adding the init file:
(org-wiki-make-menu)
The user can set the org-wiki template used to create org-wiki files by changing the custom variable with
M-x customize-variable org-wiki-template
The default template is:
# TITLE: %n
# DESCRIPTION:
# KEYWORDS:
# STARTUP: content
- [[wiki:index][Index]]
- Related:
* %n
where:
- %n is replaced by the page name
- %d is replaced by current date in the format year-month-day
This variable can also be set programatically with:
(setq org-wiki-template
(string-trim
"
# TITLE: %n
# DESCRIPTION:
# KEYWORDS:
# STARTUP: content
# DATE: %d
- [[wiki:index][Index]]
- Related:
* %n
"))
- M-x org-wiki-index to go to index.org
- New pages can be created with
M-x org-wiki-link
that asks for wiki word and inserts at point a hyperlink to the wiki page. - References to existing pages can be inserted with
M-x org-wiki-insert
.

M-x org-wiki-asset-insert-file
- Insert a link to an asset file that can be opened with Emacs at cursor position. This is an ordinary org-mode link.
Use this file for files supposed to be opened with Emacs such as Python, bash scripts or source codes.
Note: Don’t use this command to insert images,
use M-x org-wiki-insert-image
instead of this.
Example: If the current page is Python and user selects the file pyscript.py it will insert a hyperlink at point as this.
[[file:python/pyscript.py][pyscript.py]]
It will be rendenred as this:
M-x org-wiki-asset-insert-file
- Insert a link to an image file at point.
Example: If the current page is Python and the user selects the file QTScreenshot.png it will insert a hyperlink to this file that will be rendered as an image when current page is exported to html.
[[file:python/QTScreenshot.png][file:python/QTScreenshot.png]]
Insert code block with contents of some asset file as an org-mode block:
Example:
If the current page is ‘Smalltalk programming’ it the user select the file ‘extendingClasses-number1.gst’ it will insert a code block with the file contents and a hyperlink to it at point.
- File: [[file:Smalltalk programming/extendingClasses-number1.gst][file:Smalltalk programming/extendingClasses-number1.gst]]
# BEGIN_SRC text
Number extend [
inv [ 1.0 / ^self
]
neg [ - ^self
]
]
# END_SRC
It would insert a content like this:
Number extend [
inv [ 1.0 / ^self
]
neg [ - ^self
]
]
It will open a helm menu containing the assets files of current page. It will open the selected file with Emacs.
Example: If the current page is ‘Smalltalk programming’ and the user select the file ‘extendingClasses-number1.gst’ it will open the file below with Emacs.
- Smalltalk programming/’extendingClasses-number1.gst
Open a menu to select an asset file of current page and open it with system’s app.

, in the directory org-wiki-backup-location.
To open the backup directory run M-x org-wiki-backup-dir.
The command M-x org-wiki-insert-symbol
allows inserting Greek
letters, math and physics symbols by providing a helm menu where the
user can select or type the name of the symbol to insert it at current
point. It can be used to quickly type equations and formulas and can
be pasted in email, forums, source code and etc.
Examples of symbols of provided:
- α (alpha), β (beta), Σ (upper case sigma), σ (sigma)
- π = 3.1415 -> Circle Area = π.r^2

The command M-x org-wiki-insert-latex
allows writing Latex formulas,
Greek letters and math symbolls quickly. It provides a helm menu where
the user can type, search and insert Latex formulas at point.
Example:
M-x org-wiki-server-toggle
Start/stop static http server at org-wiki directory.
This command actually runs python -m http.server --bind <host> <port>
at the org-wiki directory. So it requires Python installed and
available in the $PATH variable.
Default value:
- host: 0.0.0.0
- port: 8000
To see your current local IP address type M-x ifconfig
. You can
access the static web site by entering the URL:
http://<your local ip address>:8000
- For instance: http://192.168.1.10:8000.
M-x org-wiki-panel
- This command provides a command panel that can execute actions just typing few keys like magit or dired buffer.
M-x org-wiki-make-menu
Shows a menu with org-wiki functions and command reminders.
Org-wiki can create backups of org-wiki snapshots stored in zip files that can be useful to avoid losses or revert to a previous state.
Set the org-wiki-backup directory. The variable org-wiki-backup-location is initially set to nil.
If the backup directory doesn’t exist yet, it is created whenever the user runs any backup command.
Note: It is assumed that the $ zip
command line application is the
$PATH variable.
(setq org-wiki-backup-location "~/Documents/org-wiki-backup")
This command requires the utility clip.jar and Java runtime to be available at the $PATH variable.
The custom variable org-wiki-clip-jar-path
holds the path to
clip.jar utility has the default value: ~/bin/Clip.jar
.
If you wish to install in Clip.jar in a different path set the variable org-wiki-clip-jar-path like this in the init file:
(setq org-wiki-clip-jar-path "~/bin/opt/Clip.jar")
You can download a binary release with:
mkdir ~/bin && cd ~/bin curl -O -L https://github.com/caiorss/clip.jar/blob/build/Clip.jar

- Formulas are displayed faster in Firefox.
- Mathml is the best Mathjax formula rendering.
MathJax Latex rendering is slow in Chrome browser and in its open-source relative Chromium browser. An alternative way to render formulas faster is set MathJax to use mathml rendering, but it is not well supported by all browsers such as Chrome e Internet Explorer.
