I'm having a problem with Codemirror where the live preview mode is not working for Markdown. I'm basically just trying to achieve the same effect as on SO. As it stands the live preview works for HTML but not Markdown. I've followed several of the demos and tried a few things with no luck and I'm here as a last resort. Here is the relevant code.

  • Optionally depends on the XML mode for properly highlighted inline XML. MIME types defined: text/x-markdown. Parsing/Highlighting Tests: normal, verbose.
  • I have a CodeMirror instance where i do not load all the possible modes upfront, i would like to load them dynamically for the languages that are used in the fenced code blocks in markdown.


Can CodeMirror in Markdown mode be told to show line breaks? Example: Here follows a Markdown line with 2 trailing spaces, which means 'I want a newline here'. And then another line with no trailing.

This extension has been deprecated due to lack of support from the original developer.

CodeMirror is a versatile text editor implemented in JavaScript for the browser. It isspecialized for editing code, and comes with a number of language modes and addons that implement more advanced editingfunctionality.

# Language Modes

This is a list of every mode in the distribution. Each mode lives in a subdirectory of the mode/ directory, andtypically defines a single JavaScript file that implements the mode. Loading such file will make the language availableto CodeMirror, through the mode option. This extension has the autoloading feature of those files, which searches fordefined mode directory and autoloads neccessary files.
