markup

A markup language with xml's extensibility with better looking syntax

Why?

I wanted to add highlight to specific lines on a code block. Markdown doesnt' support this and it isn't easy to extend the grammar. So i designed this language.

Syntax

code-block(highlights: [1, 3..5], lang: "ts") {
    "
        function add(a: number, b: number) {
            return a + b;
        }
        const result = add(1, 2);
        console.log(result);
    "
    p { "a js snippet" }
}

code-block defines a node. You pass your arguments between parentheses. All the arguments must be named. If you don't have any arguments you can omit the parentheses. [1, 3..5] defines a list that contains number 3 and range 3..5. The second number in range sytax is optional so you can define an open-ended range like 0... String literals uses " and are also a node, so you can pass them as children to other nodes.

Note

There are still things i need to do like a trait for transforming the AST to something other mediums can understand. Another thing is escape sequences to string literals.
