I'm trying to create an (ideally) all-in-one cross platform tile based map/sprite/image editor for a game engine, since the current official one is Windows only and doesn't play nicely with WINE/Mono. Instead of building one from scratch, I figured it might be easier to create an extension for Visual Studio Code, but side panes don't seem to be interactive, and I'm having trouble getting it to open an electron window.
Is this possible, or should I just build it from scratch with electron?
That won't work. Visual Studio Code is a code editor, which supports extensions that can either add functionality to the IDE itself or provide HTML content to show in an own pane. This is not enough (and not made) for a full featured editor-in-editor scenario (interaction is limited).
I've built an extension which has a graphical view of a graph (see the last image) using D3.js, with limited interaction capabilities (you can select/drag a node and pan/zoom with the mouse).
Better is probably to go level down and start with Electron (on which vscode is based). This would allow you to write any desktop application that can be written in HTML/JS.
I am using Visual Studio Code in Mac to do web programming.
I see we could use shift+cmd+v to launch a preview and cmd+k v to launch a preview in a separate window.
But once we modify code and save it, does anyone know how to reload and update the preview (by shortcut by preference)? Additionally, is it possible to automate the updates?
Moreover, I have opened the Debug panel, once I click on the green button, it lets me Select Environment:
Does anyone know which one I should choose to debug client side HTML+JavaScript programs?
1.) The "Preview" you mention is for Markdown files. Its not supposed to render a proper HTML preview, that's why it doesn't work or refresh. As soon as you use it with Markdown files, it updates / refreshes as you type.
But there are a couple of HTML preview extensions in the marketplace, just search for "HTML Preview" and you should be able to find some.
2.) None of those options in your screenshot, VSCode does not ship with a client side debugger by default.
But you can install Debugger for Chrome which uses Chromes debugging protocol. Detailed instructions on how to use it are in the extensions README.

Is there a way to display .md files offline so we know what it will look like once it's uploaded in Github? I'm referring to showing the README.md file as it would come out in Github, and not as for editing purposes.
Needs to work on Mac and Windows since I use both.
There are a few Chrome plug-ins that work well. I've been using Markdown Preview Plus.
After install, enable "Allow access to file URLs" in Extensions (menu > More tools > Extensions or enter URL chrome://extensions/ instead).
Then drag-n-drop a Markdown file onto Chrome and use your favorite editor to edit.
I wrote Grip a while ago to do exactly this. It renders exactly like it does on GitHub and provides several additional options too:
In addition to READMEs, Grip can renders GitHub comments and issues
Click through local links to render other .md files
An API to use in your own projects
Export to an HTML file
Install with pip:
pip install grip
Then go to the directory that contains your README file and run:
grip
Pass -h for additional help and options.
Here's a screenshot of Grip rendering Grip's README:
Check it out here.
Atom by Github. Gives you a side by side preview.
Visual Studio Code - the new editor by Microsoft also provides very good support for markdown editing.
You can download it from here.
The editor provides good support to toggle between the markdown code and the preview mode.
It also provides reasonably good intellisense support for all the markdown syntax.
The editor is free for use and is also cross platform (works on Linux, Windows and Mac).
For more details you can check on their website
Late to the party, but have a look at MarkdownPad.
See Python-Markdown-Editor
It is based on :
Python-Markdown
Pygments (code block syntax highlighting)
CodeMirror (javascript code editor)
Bottle
Install with pip :
$ pip install markdown-editor
It features when-you-type preview, code highlight, fenced code blocks, github style
it can be used by commandline :
$ markdown_edit
$ markdown_edit README.md
$ markdown_edit -f readme.html README.md
I created this to build a tool for sending code reviews, it is easily extensible, by importing it as a module you can add custom actions.
I just installed https://github.com/ypocat/gfms. It does a very good job rendering github flavored markdown. It detects changes in your markdown, so you just put your browser and editor side-by-side. It is Node.js, so it should work fine on any platform.
If you have Node.js is installed, the installation is simple:
sudo npm install -g gfms
gfms --port 9999 (in your project directory)
http://localhost:9999/ (open with any browser)
I found a way to view it in PHP. After doing some more snooping I found 2 solutions for offline and online viewing of .md files:
Offline: https://github.com/WolfieZero/Markdown-Viewer-PHP
Online: http://daringfireball.net/projects/markdown/dingus
I recommend the offline version so you can do your editing even while you're doing your business on the throne. :)
There are people who does not use Google Chrome. There is a Firefox add-on called Markdown Viewer which is able to read Markdown files offline.
pandoc is a nice Text-To-Text conversion tool that solves the problem of offline visualization of your Markdown. Just issue:
pandoc -f markdown -t html README.md > README.html
have you tried ReText? It is a nice desktop Markdown editor
I found MarkView Google Chrome extension pretty useful, actually it's working like a charm:
MarkView is a Chrome extention for editing and viewing markdown file with an outline view, support multiple table format styles, code block syntax highlight and Github Flavored Markdown.
Features:
Editing and Viewing markdown file in web page style.
Auto reload local file when file is changed (Post-installation:
select "Allow access to file URLs" option in chrome://extensions/)
Show outline beside the content in scrollable way
Have buttons for GoTop, ViewSource and GoBottom
Support Github Flavored Markdown table styles and code highlight.
Highlight the code area for programming languages(eg. ```ruby)
Support web pages printing with decent outlook(Chrome->File->Print...)
Responsive: when the window size small than 940px, outline section will
automatically hidden; resize bigger than 940px, outline section will display.
MarkView will view all markdown files except those under raw.github.com
because that subdomain only displays the source.
More features have been added to MarkView:
WYSIWYG markdown editor
Themes and Code Styling Selection
Support Footnotes1 ↩
Instant Slides Presentation
Document Custom Styling
Add Theme CSS and Select
Add Code Style and Select

I like the vertical splitter in Downmarker, you can see the changes as you write!
You can use texts as a md viewer and md editor, its lightweight and neat.
Geany has a plugin for markdown which does a fair job, giving you also a Markdown preview in the sidebar. It also runs on Linux, Mac OS X and Windows.
To use it, install geany, then install the package geany-plugin-markdown and select it from the plugin manager.
I just coded up an offline markdown viewer using the node.js file watcher and socket.io, so you point your browser at localhost and run ./markdownviewer /path/to/README.md and it streams it to the browser using websockets.
markdownviewer https://github.com/Hainish/markdownviewer/
There is also StackEdit. It will work both online and offline (it uses your browser local storage).
You can also connect it with Dropbox or Google Drive to see files hosted on the cloud.
If you're a vim person, you can try the vim-preview plugin. Simply install it into your ~/.vim directory with your method of choice. Then you can open a Markdown file with vim and use the command :Preview which will open a new window in your browser and display the end result.
Consider Strapdown.
Strapdown is Javascript-based solution that renders the markdown content in the browser, which makes it great for offline-viewing.
From their own description:
Strapdown.js makes it embarrassingly simple to create elegant Markdown documents. No server-side compilation required.
So rename your .md markdown file to .html, and surround it with:
<xmp theme="united" style="display:none;">
# Markdown content here
…
</xmp>
<script src="http://strapdownjs.com/v/0.2/strapdown.js"></script>
and opening in any browser will show rendered HTML. Added bonus: you can easily change the theme.
One of the simplest resources that works well on MacOSX is the Markdown Quick Look plugin found at InkMark. After installing this on OS X 10.9+, you simply select a markdown file in Finder and tap the space bar. I am not certain if the results are correlated 100% with Github but they are pretty good and make for a tiny unobtrusive offline viewer only solution. Mashable also wrote an article on 78 different tools if you'd like other options.
For MAC I use Marked, for Windows I use Muto-Mark. Both support the GH stylesheet.
An easy solution for most situations: copy/paste the markdown into a viewer in the "cloud." Here are two choices:
Dillinger.io
Dingus
Nothing to install! Cross platform! Cross browser! Always available!
Disadvantages: could be hassle for large files, standard cloud application security issues.
For OS X, Mou is very nice, and it comes with two GitHub CSS themes.
Check out Haroopad. This is a really nice #markdown editor. It is free and available for multiple platforms. I've tried it on Mac OSX.
You can use extension called Markdown Syntax Highlighting for Notepad++. It is available on Github
After installation, new option in the Language dropdown will be appeared
From now I use http://marxi.co/. Marxi.co has online and offline version.
I frequently want portable applications. For this, I found
http://cloose.github.io/CuteMarkEd/ (I have just tried it briefly, and it seems to work fine).
http://markdownpad.com/faq.html#portable
RStudio can handle markdown files and convert them into html and pdf. If you already have it, you can use RStudio (it is an IDE for R programming language). It is free and open source, and works on Windows, Mac and Linux.
Remarkable, certainly a great tool.
Note: Not available for Mac
Features:
Live preview
It's free.
Extremely lightweight
Export to HTML, PDF
Download: https://remarkableapp.github.io/
Edit 2022
I use and love Mark Text now. (https://marktext.app)
You may use Scribefire Next.
It's a Mozilla Firefox browser plugin. Just install the extension and fire up Firefox. Customize your toolbar and place the Scribefire shortcut to it. And since it's a browser plugin, you can use it in Mac, Linux and Windows.
When you want to write in Markdown mode, just click Edit Code from the Scribefire window.
Now to meet your purpose, go to Edit Code mode and copy all the texts and paste it to your .md file and upload.
There is no live preview feature for this, you have to toggle Edit Code and Edit Visually to preview your text.
I'm using it in my Linux Mint box:
Update:
It's year 2014, need to add some other awesome tool here for other readers and researchers. Just recently used Brackets + Markdown Preview Extension.
