Note-taking app with Markdown & code snippets (Web app or OS X) [duplicate]

Question

Besides Quiver, is there any other OS X or Web-based note-taking app that has:

• Full Markdown support, including the ability to write and render code snippets.
• List view to browse the notes.
• Does have the usual stuff like tags & search.

(Quiver by the way supports code snippets, but it's doesn't use the Markdown syntax for that, so sadly it's not good for me.)

Answer 1

You could look at doing your note taking using iPython/Jupyter Notebooks.

• Full Markdown Support in several flavours
• MathJax for equations.
• HTML support
• Not quite WYSIWYG but as soon as you move on to the next cell the cell that you have been working on is rendered.
• Embed local or remote files
• Code snippets in hundreds of programming languages with full syntax highlighting
• Can also embed data from the web
• Can generate charts, (including based on live web data)
• Code only cells can also be executed and the resulting output displayed in multiple programming languages, (depending what you have installed), including python (default), Julia, R, Bash, Haskell, Ruby, Perl.
• Save to ipython notebooks and export to Markdown, HTML, reST or pdf.
• Automatically saves your work in progress every few minutes
• Allows reverting to specific checkpoint.
• Free - gratis & open source
• Runs on multiple platforms including OS-X, Windows, Linux

Answer 2

Markdown Notes would be a good contender here. It has markdown, code highlighting and live preview, among other things.

There's a live demo on the front page.
