ast.last(type)

Returns the last child node of given type.

Parameters:

• {String=} type

Returns:

• {Node} node

Example:

    var node = ast.last()
    node.content = 'panda';

Example:

    var node = ast.last('commentML');
    node.content = 'panda';

ast.map(function)

Calls the function for every node in a tree. Modifies the tree!

    ast.map(function(node) {
        if (node.type === 'commentML') node.content = 'panda';
    });

Test

To run tests:

npm test

This command will build library files from sources and run tests on all files in syntax directories.

Every test has 3 files: source stylesheet, expected AST and expected string compiled back from AST to css.

If some tests fail, you can find information in test logs:

• log/test.log contains all information from stdout;
• log/expected.txt contains only expected text;
• log/result.txt contains only result text.

The last two are made for your convenience: you can use any diff app to see the defference between them.

If you want to test one specific string or get a general idea of how Gonzales works, you can use test/ast.js file.
Simply change the first two strings (css and syntax vars) and run:

node test/single-test.js
