JavacTo - translate java source to D

[Patrick via Digitalmars-d-announce]

Hello,

I'm pleased to announce a new java prototype application that is 
designed to translate java source into D source. Or any other 
language that support package, class, interface, and enum 
constructs and provides a built in memory garbage collection. 
Supporting D with JavacTo was my first choice!


JavacTo available at:
https://sourceforge.net/projects/javacto/

Please see the "How To use JavacTo.pdf" part of the download 
package for more information.


This tool is designed to explore the challenges faced in 
translating from one language to another. For example what type 
of code is suitable for auto-translation and what code will 
required complete rewrite? What level of automation can be 
expected? What java packages should be translated and what 
packages can be skipped? Are helper classes a good approach in 
bridging java to other language specific features? These are just 
a few questions that I've been working on as I've been writing 
this tool.


I think JavacTo is a good starting point for people who are 
interested in this topic.


IMHO moving java opensource projects to D has the potential to be 
an incredible win for the D language/community.

New version of JavacTo available.

[Patrick via Digitalmars-d-announce]

Please to announce: 

A new version of JavacTo available for download. Version 1.1
https://sourceforge.net/projects/javacto/


Features:
* Updated JavacToD visitor. Almost 100% parsing success with 
dscanner and JDK package subset (see results below).


* Updated JavacToJava visitor.

* Source and Target Text pane mouse click integration with List 
and Tree views. Click in a text pane and the list and tree view 
will update with the related visitor node. Very cool.


* New search capabilities. Text and Tree.Kind search.

* Support for command line translation (non-UI, very fast).

* Target highlighting is now automatic (matches java source 
highlighting). No need to add code to highlight. In fact, 
manually highlighting code is discouraged.


* Process dialog when reading large .zip/.jar files.

* Other UI enhancements.


Results with dscanner:
Package  Total files   Failed
java.util   362 15
java.math   8   1
java.net78  0
java.nio126 1
java.io 83  0
java.lang   219 4

Success is attributed to dscanner providing no output when 
parsing a file.


Failures are all attributed error output from:
* Java’s hybrid enum definition. (Which I believe will take a D 
enum and custom class to implement.)

* Java’s lambda method definition.

Successful parsing with dscanner I believe is a major milestone 
for JavacTo. This suggests a good percentage of java code can be 
automatically translated to D. Clearly this is not a definitive 
statement just yet, but an encouraging move in the right 
direction. Dscanner can now be used to format the JavacToD 
generated code for code review. And  critique the quality 
of the code generated (or worse, the quality of the java code :).


It’s clear the next step is to successfully compile the code. 
With effort working towards a successful compile, there's no 
doubt more changes are in store for the JavacToD visitor code. In 
addition, I’m anticipating some hand editing of the generated 
code will be required while other code will be thrown out. 
Perhaps helper code will be warranted as well. In any case, we'll 
see where the compiler takes us as we work towards a weighted 
balance of auto-generated code to hand editing.  Anyway, to be 
clear, the current objective (hope) is to create a D library 
based on java JDK subset listed above (or something close to it). 
This library can then be used as the bases for translating other 
open source java projects to D.


So… more work to be done.

It's the end of an era. Symantec bought my company, Zortech, 
and now is bought in return. The D community, and myself 
personally, owe a debt of gratitude to Symantec.


Thank you, Symantec!



For those who haven't see Symantec C++ product before, behold

Just above "VERSION 7" you'll see the golden ticket! "SYMANTEC

Oh, and its still in its shrink wrap :)
