Generates invalid C-code about spag

[rrozansk]

Hello @gvanem, it looks like you are trying to use the parser generation flag (-p) which is not yet supported as described in the README. See here: https://github.com/rrozansk/SPaG#status. As for '_NULL', it is a special definition that may not be present in all compilers. Finally, if you need a compiler generator to build the scanner/parser, may i suggest something like 'Flex/Lex' or 'Yacc/Bison' as an alternative to SPaG as these are more reliable battle tested programs which may offer much more extensive features, help, and support.

Can you name one compiler that does not have NULL? You add a #include <stdio.h> and NULL is almost always defined to 0.

I know these tools. But (except for the awful .json files) it seemed your tool looked more compact.

Hey @gvanem, I cannot name any C compilers without NULL, but that is not what I am stating. Rather, that '_NULL' is not necessarily the same as 'NULL'. The former is an implementation detail and not portable. The latter is what should be used as it is what is actually defined in the stdio.h header file as you described.

As for the JSON files, I concur that they could be in a better format. This way was chosen for simplicity as it makes parsing the input easier as python natively support JSON.

Lastly, I would like to say that this project has mostly gone stale since I have not had any time to work on it in quite a while. If you are up to the task and the compactness of the tool appeals to you then you can certainly feel free to contribute and it would be very much appreciated!

Yes, off-course not. I meant that one cannot use NULL in an enum-list like you did.
Hence _NULL (or JSON_NULL in this case) should be used.
Closing this now.
