[Etoys] translation issue in addTranslatedList:

Hi, Korakurider,

This is getting closer, but it still would require changes to all of  
those 25 methods that call #addTranslatedList:, and also would  
spuriously grab literals from many other methods that happen to have  
big literals in them but which have nothing to do with  

I'm still quite willing to append #translatedNoop calls to the array  
literals in the 25 methods, but I think there's perhaps a better way  
that requires writing only one new method and making a one-line  
modification to one other method, and which might be more generally  
useful in the translation regime in any case.

What I suggest is that one implement a method named something like:

     GetTextExporter2 >>  

whose first argument is an index-list and whose second argument is a  
selector, and whose third argument is the categories dictionary  
common to the protocol of all the appendXXX methods in GetTextExporter2.

The one guaranteed use-case of this method would be the addition of  
the following line to the code for GetTextExporter2 >>  

   self appendStringsAtPositions: #(1 3) ofArgsInSendersOf:  
#addTranslatedList: into: categories.

The job of appendStringsAtPositions:ofArgsInSendersOf:into: would be  
to retrieve all senders of the given selector, scan the parse tree of  
each retrieved method, locate every send of the given selector within  
the method node, find out if the argument of the send is an array  
literal, and, if it is, iterate across that array, and for each  
element of it which *itself* is an array, pick off the strings to be  
translated from the index positions requested in the call, and  
integrate them into the ongoing categories structure.

Isn't this feasible?  Or am I missing something?

If we come across other situations where translatable strings are  
buried within elements of complex literal arrays we could then handle  
those calls in the same way.
