BooML Source Online

Follow-up to BooML SourceForge Project Pending from codeMonkey.Weblog();

The source for BooML is now online. The project is hosted by SourceForge. link

So far I've just got the source into SubVersion. I'm so busy at the moment (too many pies, not enough fingers!) – but I really must get some docs online too.

BooML SourceForge Project Pending

Follow-up to BooML – Language Integrated XML in Boo from codeMonkey.Weblog();

I have submitted a project request to SourceForge for BooML. I hope it is processed faster than Specter was!

BooML – Language Integrated XML in Boo

Creating XML using the .NET XmlWriter object model tends to make your code look awful. I realised that using some mackery I could make Boo support creating XML right in the language. Thus was born "BooML"

Here is a little example.

import System
import System.IO
import System.Xml
import BooML

class Book:
    [property(Title)]
    private _title as string
    [property(Author)]
    private _author as string

def GetBooks():
    return [
        Book(Title: "Foo Bar", Author: "Bob Smith"),
        Book(Title: "Test Title", Author: "Andrew Davey")
    ]    

[XmlLiteral()]
def GetBooksXml(books):
    books:
        for book as Book in books:
            book:
                @id = book.GetHashCode()
                title book.Title
                author book.Author

    
xml = GetBooksXml(GetBooks())
print xml.ToString()

The resulting XML is:

<?xml version="1.0" encoding="utf-8"?>
<books>
  <book id="54267293">
    <title>Foo Bar</title>
    <author>Bob Smith</author>
  </book>
  <book id="18643596">
    <title>Test Title</title>
    <author>Andrew Davey</author>
  </book>
</books>

The magic is in the XmlLiteral AST Attribute. It transforms macros (in the example: books, book, @id, title and author) into XML macros. The XML macros then in turn create the XmlTextWriter calls.

I think this could be a really powerful language enhancement for people doing web development who want to return abitrary XML from methods.

I may start a SourceForge project to open source the development.
