When you are tired of a white screen and like a night mode, click on the little moon and turn on the night view of HedgeDoc.
The editor view, which is in night mode by default, can also be toggled between night and day view using the the little sun.
You can upload an image simply by clicking on the upload button .
Alternatively, you can drag-n-drop an image into the editor. Even pasting images is possible!
This will automatically upload the image to imgur, Amazon S3, Minio or the local filesystem (depending on the instance’s configuration), nothing to worry about.
If you want to share an editable note, just copy the URL.
If you want to share a read-only note, simply press the publish button and copy the URL.
Currently, you can save to Dropbox (depending on the instance’s configuration) or save a Markdown , HTML or raw HTML file locally.
Similarly to the save feature, you can also import a Markdown file from Dropbox (depending on the instance’s configuration), or import content from your clipboard , which can parse some HTML.
It is possible to change the access permission of a note through the little button on the top right of the view.
There are four possible options:
Owner read/write | Signed-in read | Signed-in write | Guest read | Guest write | |
---|---|---|---|---|---|
Freely | ✔ | ✔ | ✔ | ✔ | ✔ |
Editable | ✔ | ✔ | ✔ | ✔ | ✖ |
Limited | ✔ | ✔ | ✔ | ✖ | ✖ |
Locked | ✔ | ✔ | ✖ | ✔ | ✖ |
Protected | ✔ | ✔ | ✖ | ✖ | ✖ |
Private | ✔ | ✖ | ✖ | ✖ | ✖ |
Only the owner of the note can change the note’s permissions.
Notes can be embedded as follows:
<iframe width="100%" height="500" src="https://demo.hedgedoc.org/features" frameborder="0"></iframe>
You can use a special syntax to organize your note into slides.
After that, you can use the Slide Mode to make a presentation.
Visit the above link for details.
To switch the editor into slide mode, set the document type to slide
.
You can look at the bottom right section of the view area, there is a ToC button .
Pressing that button will show you a current Table of Contents, and will highlight which section you’re at.
ToCs support up to three header levels.
Every header will automatically add a permalink on the right side.
You can hover and click to anchor on it.
You can look in the bottom right section of the editor area, there you’ll find a button with SUBLIME
on it.
When you click it, you can select 3 editor modes, which will also define your shortcut keys:
This editor provides full auto-complete hints in markdown.
:
to show hints.```
, followed by another character to show syntax highlighting suggestions.#
to show hint.[]
to show hint.{}
to show hint.!
to show hint.The first level 1 heading (e.g. # Title
) will be used as the note title.
Tags can be specified with YAML metadata at the start of the note. Those tags will show in your history.
---
tags: features, cool, updated

You can provide advanced note information to set the browser behavior (visit above link for details):
Use the syntax [TOC]
to embed a table of contents into your note.
You can type any emoji like this
See full emoji list here.
We support many programming languages, use the auto complete function to see the entire list.
var s = "JavaScript syntax highlighting";
alert(s);
function $initHighlight(block, cls) {
try {
if (cls.search(/\bno\-highlight\b/) != -1)
return process(block, true, 0x0F) +
' class=""';
} catch (e) {
/* handle exception */
}
for (var i = 0 / 2; i < classes.length; i++) {
if (checkCondition(classes[i]) === undefined)
return /\d+[\s/]/g;
}
}
If you want line numbers, type =
after specifying the code block languagues.
Also, you can specify the start line number.
Like below, the line number starts from 101:
var s = "JavaScript syntax highlighting";
alert(s);
function $initHighlight(block, cls) {
try {
if (cls.search(/\bno\-highlight\b/) != -1)
return process(block, true, 0x0F) +
' class=""';
} catch (e) {
/* handle exception */
}
for (var i = 0 / 2; i < classes.length; i++) {
if (checkCondition(classes[i]) === undefined)
return /\d+[\s/]/g;
}
}
Or you might want to continue the previous code block’s line number, use =+
:
var s = "JavaScript syntax highlighting";
alert(s);
Somtimes you have a super long text without breaks. It’s time to use !
to wrap your code:
When you’re a carpenter making a beautiful chest of drawers, you’re not going to use a piece of plywood on the back.
Using the syntax below to specifiy your name, time and color to vary the blockquotes.

It converts “HTML”, but keeps intact partial entries like “xxxHTMLyyy” and so on.
When changes are made to a note previous versions of the note are stored as Revisions
, if you ever need to return to a previous save you can find all the note revisions by going to Menu
-> Revision
.
The note history on the left displays each revision with a timestamp allowing you to quickly select a revision for the desired date and time. Selecting a revision on the left will display the revised note to the right, the revision will display the changes made with colorization to indicate additions/removals.
In addition to browsing the revisions, you can download a selected note revision or revert the current note to the selected revision.
