Hi,
This is my first post on this mailing list. so let's start by a little
presentation. I'm a French young researcher (aka 'postdoc'), working on the
definition of mechanisms to support separation of concerns approaches.
I'm currently using ANTLR & StringTemplate to implement a translator associated
to a prototype. By the way, these two tools are impressive (I previously only
work with ANTLR for another project).
However, I'm encountering a (big) issue. The translator I'm designing must
support the definition of a "require" mechanism. A source file "x" must be able
to require the content of another source file "y".
The translator first start by building an AST, and then a tree grammar visit
the AST and use the appropriate templates. My first idea is to implement
something like the following snippet in the grammar:
require: 'require' fileName=STRING ';' {
build the AST associated to $fileName;
insert its content inside the current
one;
}
however, I have no idea on how to implement the second actions, that is,
including the content of another AST into this one. I'm not even sure this is
the right solution to my problem :'(. Is preprocessing a better solution?
Any ideas?
Cheers,
