as part of our application i need to build component that will output code in php and asp that have the same functionality ( and maybe latter jsp ) . how can i design this kind of component to be generic as possible ?
You need to be able to create a parse tree out of all input languages.
For each output language, you will need to create a set of tree transforming grammar.
You may also require a runtime library to help translate routines that are not available in your output language.
