I am currently using Textmate to create Markdown documents, but it requires me to press CtrlOptionCmd + P everytime I want to 'update' the Markdown output window. Essentially I am using it like a word processor.

Is there a Markdown editor for Mac OS X which supports wysiwig/live update of the content? Perhaps Textmate already does this?

Searching the same for Linux, still this question is very useful (there are some portable programs listed here) –  Dacav May 7 '12 at 14:58

If you want to use TextMate, change your file's language association to 'HTML'. In the Preview window there is a drawer that offers the option pipe the text through 'Markdown.pl'. (See screenshot).

The alternative I use for Makrdown is not an officially released app but personally I use markdownlive by Jonathan 'Wolf' Rentzsch. It's open source available on GitHub and will require you to compile it using Xcode. It also allows you to copy the Generated HTML (what I like to use it for quite a bit).

I tried markdownlive. It works, but like you said its in development and is quite primitive in the way of syntax colouring. I will try you other method soon. –  Brock Woolf Aug 12 '10 at 6:54

you do not have to set your file type to html. if you use the markdown bundle, you just need to remove the key equivalent activation of preview in the bundle settings. then textmate's show web preview in the window menu will give you a live preview. –  yanokwa Apr 25 '11 at 19:08
    
What about multimarkdown? –  Kirk Strobeck Aug 19 '11 at 16:21

You don't have to build MarkdownLive yourself: github.com/rentzsch/markdownlive/downloads –  Matt Ball Feb 16 '12 at 18:21
    
+1 For @yanokwa's comment. I particularly like this fork of the markdown plugin, which nicely preserves things like indentation for unordered lists: github.com/fletcher/markdown.tmbundle –  user72923 Nov 4 '12 at 22:30

There is also "Mou", a live editor for Mac OS X (Lion). It's still in beta, but works great! http://mouapp.com/

When current available Markdown editors are almost all for general writers, Mou is different: It's for web developers. Syntax highlighting, live preview, fullscreen mode, auto save, powerful actions, auto pair, incremental search, custom themes, HTML export, enhanced CJK characters support.

Mou looks great, but requires Lion. –  Thilo Dec 15 '11 at 9:53

Mac only, Marked provides markdown and multi-markdown preview for any text editor. The preview is updated when you save the text file.

MarkdownPad is for Windows, but provides live preview.

ReText is available for other platforms and offers a live preview of rendered Markdown:

ReText is a simple text editor for Markdown syntax. It is written in Python using Qt libraries, able to run on any platforms (Linux and BSD are officially supported)

Although not officially supported, there are Windows installation instructions as well; however, I had to make a few modifications to get them to work (the complete set with my corrections is shown below):

Installation

  1. Install Python27
  2. Install PyQT precompiled for PyQt-Py2.7-x86-gpl-4.8.3-1.exe PyQt-Py2.7-x86-gpl-4.8.4-1.exe
  3. Install easy_install setuptools-0.6c11.win32-py2.7.exe
  4. Update your My Computer's Environmental Variables. Click Start, right-click My Computer and select Properties, select the Advanced tab, then click Environment Variables.
  5. Under System Variables, click New. Under variable name enter PYTHONPATH. Under Variable value enter C:\Python27\Lib\;C:\Python27\Lib\site-packages\
  6. Select the System Variable PATH click Edit. Update the PATH variable value by adding C:\Python27;C:\Python27\Lib\site-packages\PyQt4\bin; to the front of the existing entries so that it reads like PATH=C:\Python27;C:\Python27\Lib\site-packages\PyQt4\bin;...
  7. Install additional Python libraries. Select Start then Run, type cmd then cd \python27\scripts. Enter:
    • easy_install Pygments
    • easy_install ElementTree
    • easy_install Markdown
    • easy_install gdata
  8. Download and unpack current ReText (ATM 0.8.1)
  9. Download and unpack ReText icons
  10. Place the unpacked icons into the ReText\icons folder
  11. Navigate to the retext.py file (probably at c:\retext). Right-click drag-and-drop retext.py and select Create shortcuts here.
  12. Right-click on the shortcut to adjust the properties.
  13. Change target to "C:\Python27\python.exe" retext.py and Run to minimized.
  14. Change the icon (which will require you to make an .ico file from one of the .png files unzipped above into the ReText/icons directory, which can be done here
  15. Change the shortcut name on the general tab if desired.

For those who want to get Marked (which I really can recommend) and still have Snow Leopard (10.6), there is a free Snow Leopard only download available through the FAQ (marked.tenderapp.com/kb/documentation/…): assets.markedapp.com/MarkedSL.zip –  Simon Lehmann Jun 6 '12 at 9:54
    
better to list each of these as separate answers –  Zac Thompson May 21 '13 at 23:40

MarkdownLive does exactly what you want, free and open source.

Download the release through GitHub, or version 1.7.1 from here.

BBEdit does this out of the box: set the current document type to be Markdown, open Preview in BBEdit, and type away. The preview window auto-updates, showing your text just the way you want it.

See page 277 of the BBEdit User Manual for details.

Emacs markdown mode gives you a live preview as you write, and also a full HTML/Browser preview with C-c C-p.

The recently revived Smultron can do that as well without pressing any keys:

  1. Set the "Preview Parser" to "Markdown" in the advanced preferences under "Really Advanced".
  2. Then open the preview window with "Tools" / "Preview". Voilà.

vim-instant-markdown is a vim plugin that shows near-instant updates in your system default web browser. It even works in MacVim, though I had to fiddle with $PATH a little.

Do you mind sharing what you did to your $PATH? –  Eric Hu Apr 11 '13 at 3:58

Windows users can use Resophnotes to write their text in Markdown and use the "HTML" icon to preview the marked up text then export the html formatted text.
