Markscript is a tool for executing JavaScript embedded in Markdown files. It's useful for writing executable documentation, or "literate-style" JavaScript code. You can run Markscript as part of your build process to make sure that your documentation is up-to-date.

npm install markscript

markscript FILES...

This will run Markscript on each of the given files, executing any JavaScript code that is found in a fenced code block. The blocks are executed individually, but every block in a file shares the same global environment. This means that you can do something like this:

var x = 'fan';

and then refer to x in a separate block:

var y = x   'tastisch';

You can also use require and console.log, just like a regular Node script:

require('assert').equal(y, 'fantastisch');

Oh, in case it wasn't obvious -- this README itself an example of executable documentation. This project's tests will fail if the assertion above fails, or if any other errors occur.

After checking out the source, run npm install in the project directory to install the dev dependencies. Use npm test to run the tests, or npm run test-continuous to have them run every time the code changes.

Before submitting a pull request, please run npm run prepublish to make sure that the tests pass and there are no lint warnings. You can do this automatically on every commit by copying bin/pre-commit to the .git/hooks directory in your Git checkout.
