[Getdp] How to add new commands to GetDP ?

[Christophe Geuzaine]

Dear Guillaume,

What kind of commands do you want to add? If you only want to add a new function (say, like "XYZ[]"), you don't actually have to modify the parser: you can simply create your new function (see e.g. Legacy/F_Coord.cpp) and add the name in Interface/ProDefines.h.

The same holds for simple resolution operations and other common constructs: see Interface/ProDefines.h.

For more exotic commands, you will indeed have to modify the flex/bison parser. Once you have made a modification, you have to rebuild the C++ version with "make parser".

Hope this helps,

Christophe

To be more precise, I am looking for some explanations on how to expend the vocabulary of the scanner and parser so that my own functions can be  recognized just as the built-in one. I have no previous experience with Flex and Bison, that is why I found myself struggling to understand what happens in the “ProParser” files. I would really appreciate your advice,
