Features

Introduction

HedgeDoc is a real-time, multi-platform collaborative markdown note editor.
This means that you can write notes with other people on your desktop, tablet or even on the phone.
You can sign-in via multiple auth providers like Facebook, Twitter, GitHub and many more on the homepage.

If you experience any issues, feel free to report it on GitHub.
Or meet us on Matrix for dev-talk and interactive help.
Thank you very much!

Night Mode

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.

Image Upload

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. :tada:

Share Notes

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.

Save a Note

Currently, you can save to Dropbox (depending on the instance's configuration) or save a Markdown , HTML or raw HTML file locally.

Import Notes

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. :smiley:

Permissions

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.

Slide Mode

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.

View

Autogenerated Table of Contents

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.

Permalink

Every header will automatically add a permalink on the right side.
You can hover and click to anchor on it.

Edit

Editor Modes

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:

Sublime (default)
Emacs
Vim

This editor provides full auto-complete hints in markdown.

Emojis: type : to show hints.
Code blocks: type ```, followed by another character to show syntax highlighting suggestions.
Headers: type # to show hint.
Referrals: type [] to show hint.
Externals: type {} to show hint.
Images: type ! to show hint.

Title

The first level 1 heading (e.g. # Title) will be used as the note title.

YAML Metadata

You can provide advanced note information to set the browser behavior (visit above link for details):

robots: set web robots meta
lang: set browser language
dir: set text direction
breaks: set to use line breaks
GA: set to use Google Analytics
disqus: set to use Disqus
slideOptions: setup slide mode options

Use the syntax [TOC] to embed a table of contents into your note.

[TOC]

Emoji

You can type any emoji like this :smile: :smiley: :cry: :wink:

See full emoji list here.

ToDo List

Code Block

We support many programming languages, use the auto complete function to see the entire list.

```javascript=
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:

```javascript=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 =+:

```javascript=+
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.

Blockquote Tags

Using the syntax below to specifiy your name, time and color to vary the blockquotes.
[name=ChengHan Wu] [time=Sun, Jun 28, 2015 9:59 PM] [color=#907bf7]
Even support nested blockquotes!
[name=Max Mustermann] [time=Sun, Jun 28, 2015 9:47 PM] [color=red]

MathJax

You can render LaTeX mathematical expressions using MathJax, as on math.stackexchange.com:

The Gamma function satisfying $\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$ is via the Euler integral

$$
x = {-b \pm \sqrt{b^2-4ac} \over 2a}.
$$

$$
\Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,.
$$

More information about LaTeX mathematical expressions here.

Diagrams

UML Sequence Diagrams

You can render sequence diagrams like this:

Alice->Bob: Hello Bob, how are you?
Note right of Bob: Bob thinks
Bob-->Alice: I am good thanks!
Note left of Alice: Alice responds
Alice->Bob: Where have you been?

More information about sequence diagrams syntax here.

Flow Charts

Flow charts can be specified like this:

st=>start: Start
e=>end: End
op=>operation: My Operation
op2=>operation: lalala
cond=>condition: Yes or No?

st->op->op2->cond
cond(yes)->e
cond(no)->op2

More information about flow charts syntax here.

Graphviz

digraph hierarchy {
  nodesep=1.0 // Increases the separation between nodes

  node [color=Red,fontname=Courier,shape=box] // All nodes will this shape and colour
  edge [color=Blue, style=dashed] // All the lines look like this

  Headteacher->{Deputy1 Deputy2 BusinessManager}
  Deputy1->{Teacher1 Teacher2}
  BusinessManager->ITManager
  {rank=same;ITManager Teacher1 Teacher2} // Put them on the same level
}

Blockquotes

Blockquotes can also be nested...
...by using additional greater-than signs right next to each other...
...or with spaces between arrows.

Lists

Unordered

Create a list by starting a line with +, -, or *
Sub-lists are made by indenting 2 spaces:
Marker character change forces new list start:
- Ac tristique libero volutpat at
- Facilisis in pretium nisl aliquet
- Nulla volutpat aliquam velit
Very easy!

Ordered

Lorem ipsum dolor sit amet
Consectetur adipiscing elit
Aenean commodo ligula eget dolor
You can use sequential numbers...
...or keep all the numbers as 1.
Aenean massa
Cum sociis natoque penatibus
Magnis dis parturient montes
Nascetur ridiculus mus
Donec quam felis

Start numbering with offset:

Images

Minion

With a title:
Stormtroopocat

Like links, images also have a footnote style syntax with a reference later in the document defining the URL location:
![Dojocat][dojoref]

[dojoref]: octodex.github.com/images/dojocat.jpg "The Dojocat"

Show the image with given size:
Minion

Footnotes

Footnote 1 link[^first].
Footnote 2 link[^second].
Inline footnote^[Text of inline footnote] definition.
Duplicated footnote reference[^second].

[^first]: Footnote can have markup
and multiple paragraphs.
[^second]: Footnote text.

Definition Lists

Term 1

: Definition 1
with lazy continuation.

Term 2 with inline markup

: Definition 2

    { some code, part of Definition 2 }

Third paragraph of definition 2.

Compact style:

Term 1
~ Definition 1

Term 2
~ Definition 2a
~ Definition 2b

Abbreviations

This is an HTML abbreviation example.
It converts "HTML", but keeps intact partial entries like "xxxHTMLyyy" and so on.

*[HTML]: Hyper Text Markup Language

Revisions

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.

Here we go, let's start

Is this any good?
