jsmd ensures that you will never have outdated and non-working JavaScript code in your README files.
npm install jsmd
jsmd ensures that you will never have outdated and non-working code in your
README files.
``
Usage: jsmd
Options:
--show display the compiled JS after execution
--help display this help message
--version display the version number
`
Just write your README files in GitHub Flavored Markdown as usual. The only thing that you have
to add is the actual assertions. So here is a small example that will hopefully
illustrate how assertions look:
`js
var fs = require('fs');
fs.unlink('/tmp/this-is-stupid', function(err) {
typeof err; // => 'object'
});
`
In this simple example we expect that the type of err is equal to 'object'.
As simple as that.
In order to verify if everything works properly just supply the desired file to
jsmd and it will verify it for you:
`
$ jsmd README.md
See the examples for more
info.
#### Which code blocks get evaluated
In order jsmd to recognize your JavaScript code elements, you have to specify
them either as "js" or "javascript".
To get JavaScript syntax highlighting, without jsmd running the code, specify the code block as "node".
`node`
var rm_rf = require('rimraf')
rm_rf('/usr/bin')
#### Hidden setup
Sometimes you don't want to put helper code into your readme file, but it's
necessary in order to perform the tests. In this case, you can simply add
special html comments which jsmd will extract and put inside the compiled file.
`
That way, GitHub won't visualize the comment but jsmd will be able to parse it.
jsmd has very simple flow, that looks like this:
* First jsmd will parse and extract all JavaScript code elements
* It will search the code snippets for "assertions". Assertions look like
this Math.min(1, 2) // => 1
* It will compile the JavaScript code with the assertions and it will try to
execute it
* It will report failures if any
`bash`
$ npm install jsmd -g
`bash`
$ npm test
`bash``
$ npm run-script coverage
Special thanks to:
* Doctest.js
* xplain - JavaScript API documentation generator that uses unit tests as examples
