Features

Introduction

CodiMD 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.org for dev-talk and interactive help. Thank you very much!

Workspace

Modes

Desktop & Tablet

Edit: See only the editor. View: See only the result. Both: See both in split view.

Mobile

View: See only the result. Edit: See only the editor.

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 CodiMD.

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 camera 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 local filesystem, 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 publish button and copy the URL.

Save a Note:

Currently, you can save to Dropbox or save an .md file locally.

Import Notes:

Similarly to the save feature, you can also import an .md file from Dropbox , or import content from your clipboard , and that can parse some html which might be useful 😃

Permissions:

It is possible to change the access permission to 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.

Embed a Note:

Notes can be embedded as follows:

<iframe width="100%" height="500" src="https://demo.codimd.io/features" frameborder="0"></iframe>

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

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:

sublime (default)
emacs
vim

Shortcut Keys:

The shortcut keys depend on your selected editor mode. By default they are just like Sublime text, which is pretty quick and convenient.

For more information, see here.

For emacs:

For more information, see here.

For vim:

Auto-Complete:

This editor provides full auto-complete hints in markdown.

Emojis: type : to show hints.
Code blocks: type ``` and plus a character to show hint. ```
Headers: type # to show hint.
Referrals: type [] to show hint.
Externals: type {} to show hint.
Images: type ! to show hint.

Title:

This will take the first level 1 header 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

Emoji

You can type any emoji like this 😄 😃 😢 😉

ToDo List:

ToDos
- Buy some salad
- Brush teeth
- Drink some water

Code Block:

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.

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]

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.

UML Diagrams

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?

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

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
Integer molestie lorem at massa
You can use sequential numbers...
...or keep all the numbers as 1.

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.
