Parsing / reading C-Header files using Java

Question

I have a C-Header file defining a pair of stucts containing multiple char arrays.

I would like to parse these files using Java. Is there a library for reading C-Header files either into a structure, or is there a stream parser that understands C-Header files?

Just for a bigger background (I'm just looking for a C-Header parser, not a solution for this particular problem): I have a text file containing data and a C-Header file explaining the structure. Both of them are a bit dynamic, so I do not want to generate Java class files.

Example:

#define TYPE1
typedef struct type1
{
char name1[10];
char name2[5];
}
#endif

Type2, Type3, etc. similar.

Data structure:

type1ffffffffffaaaaa

Answer 3

As already mentioned, CDT is ideal for this task. But, unlike the one described above, I used it from inside the plugin and was able to use IFiles. Then everything is so convenient. To get "ITranslationUnit", simply do:

ITranslationUnit tu = (ITranslationUnit) CoreModel.getDefault().create(myIFile);
IASTTranslationUnit ias = tu.getAST();

I was looking for a special #define, so I could just:

ppc = ias.getAllPreprocessorStatements();

To get all the pre-processed code statements, each statement in the element array. Absolutely easy.

You can try using ANTLR . To do this, there must already be some existing C grammar .
