Subject: compiler for structure-shy language

Reminder: we continue with the Demeter Seminar today at 4pm in 149 CN:

About the message below:
XSLT is an example of a structure-shy language for writing translators
for XML documents. It supports features like "from A to B"
and "from A bypassing X to Y".
I was also thinking that it would be useful to write a compiler
with a similar goal as the XSLT/XML compiler for
programs that are written in Java and DJ. The idea would be to find
statements like
new TraversalGraph("from Customer through LastName to edu.neu.ccs.demeter.Ident",
Main.cg). fetch(aCustomer)
and to replace them by (for example):
aCustomer.getHRData().getName().getLastName().getIdent()
The goal is to improve performance.

>The Sun[tm] XSLT Compiler is a Java[tm]-based tool that creates fast
>and lightweight Java class files for transforming XML files according
>to an input XSL file. The XSLT Compiler works by parsing an input XSL
>file and then creating a Java class file that performs the
>transformation instructions specified within the XSL file. After this
>one-time compilation, the output Java class, or translet, can be used
>repeatedly to transform XML files appropriate for the XSL file. The
>benefits of this process are that the translet is faster and smaller
>than traditional transformation engines. In this talk I will discuss
>a few of the main design decisions we faced during the development of
>the XSLT Compiler. The first part of the talk will include a brief
>introduction to XML and XSLT. The second part of the presentation will
>be devoted to some architectural aspects of the XSLT compiler. Time
>permitting, I will present a demo of translets "in action" running on
>a Palm Pilot.
