[Dia2code-general] Request fo comment - a simple code preservation implementation

[Leonard W. <le...@ne...>]

Hello,

Here is a preliminary dia2code version that preserve the methods source code.

I've only adapted java and php generators for now.  In order to make it work, 
you must add a @diaoid <oid> tag in the methods comment field.
<oid> must be unique for a method in a class, and may be any string without 
spacing character, eg. you can use method name or a number:
"My method description - @diaoid setList"
"My method description - @diaoid m001"

This should be a temporary constraint as iasked the dia developer team to add 
an oid attribute to methods and attributes in dia XML format. I've included 
for a sample diagram under tests/categories.dia.

I fixed some segfaults, among which a tricky one in parse_diagram.c due to a 
<parent> tag in (i guess recent) dia XML.

I've added an hidden --debug <level> switch to show a few informations about 
the generation process.

Most of the code parsing stuff is in source_parser.c (new file). It is very 
basic for now, a major "Todo" is to interprets comments and quoted strings 
correctly.

As the list may not accept attachements, you can get the tarball 
@ http://lwest.free.fr/dia2code-codepreserve.tgz

I also have a question about dia2ode history: what is the right way to output 
code , as there are so many functions to do that (d2c_printf, emit, 
fprintf....)
