Hello All,
I would to ask you if somebody has experience or can give direction in a
new project I have.
I have a meta language description (in xml) from which I should generate
code on different
languages. In my case, lisp and tcl.
You need to provide more information of your description to get some
specific hints. The other day a had a xml file containing a business
object model with hierarchy and relations. Then I wrote a code
generator to build a module with Python classes for each business
item. The code generator created properties for lazily resolving
relations modelled via ids in the database and stuff like that. This
was very straightforeward using a simple print statements like the
following:
print "class %s(object):\n" % class_name
print " def __init__(self, %s)" % constr_arg
...
Cheers,
Jan
In fact in xml I have something like that:
A metafunction in fact kind of
<metfunc name=call_back_do_stuff_function>
<parameter>x</parameter>
<parameter>y</parameter>
</metafunc>
I have to generate the call_back_do_stuff_function(x,y) in lisp and tcl
according to a catalog of specs
of what this function must do generically.
I can do prints for each metafunctio I read but my concern is is there
std libs to help to have good design
and methodology. Is it interesting to use command module of something
like that, is interesting to use
a parser like pylex or pyparsing? I have 50 metafunctions in catalog for
now.
In fact, my point is to have a great extensive design methodology.
Strategy pattern would suit?
Other patterns? std modules?
Lots of question here!
Regards
Karim
Any idea in term of design, examples, links will be appreciated!
Kind Regards
Karim
