Hello,
Continuing on my experiment with the DSL I imagine...
Client Code:
obj =: bo 'customer' NB. create is now called bo
obj add ('name';'MyName')
=========================================
This should result in :
0) An instance obj of type customer. (I used Bill's version here)
1) an attribute added to the class of obj
2) the attribute instantiated in the specific instance obj.
I tried the following (based on the above recommendations...) for the add
verb -
add =: 4 : 0
attr =. 0{::y
class =. ; {. @ copath x
s =. attr,'_',class,'_'
NB. s =: attr,'_',class,'_ =:', 1{::,y
". s
s =. attr,'__x',' =:', 1{::,y
". s
)
As you can see, I am creating strings and executing them.
Q1: Is there a simpler way to inject names into locales?
Then, I look at the names I have so far created:
conames ''
0 1 2 base customer j jgl2
jijs jprint jproject jregex jscriptdoc jview y
z
names_customer_ ''
names__obj ''
COCREATOR name
name__obj
+------+
|MyName|
+------+
Q2: Why is the names_customer_ empty? Is it because of lazy evaluation of J?
By this I mean that since the attribute is not assigned a value, the
namespace of 'customer' does not record the attribute called 'name'.
Q3: Later, I would like to apply reflection techniques to look into the
objects I have created of the various type (here instances of locatives) -
for this I assumed that I need to introduce the attribute in the class
and assign value to it in the object instance. But, with the issue mentioned
in Q2, I donot know how to proceed.
Thanks for any pointers here,
Yuva
