How does it work?
MagNumDB is a database that contains about 300,000 items. These items are constants, names, values
all extracted from more than 4,000 header files (.h, .hxx, .hpp, .idl, etc.) provided by standard Windows and Visual Studio SDKs.
Some values have been extracted from the very special uuid.lib file that contains the value of thousands of guids and property keys, not present anywhere else in header files.
To build this database, we have written a powerful C/C++ parser named C2P5 (for C/CPP/PreProcessor/Parser), tailored specifically for this task.
C2P5 is capable of preprocessing, parsing and partially evaluating all header files as if they were included in a one big virtual project (that of course, does not compile). It currently supports the following preprocessor and C/C++ constructs:
The parser remembers dynamic preprocessor definitions (#if, #ifdef, etc.) that are conditions for constants definitions and expression computation.
All parsed items are saved in the database, as well as the associated conditions.
There may be more than one item corresponding to a given name, if there are differences in their associated conditions.
C2P5 supports the following types of constants, regardless of the way they are defined in source files:
C2P5 and this MagNumDB web site are written in C# and use a Lucene database as a full-text search engine.
C2P5 uses a custom ANTLR4cs C grammar for expression parsing, not for preprocessor parsing.
Frequently Asked Questions
Some important points to note:
Here are some example or custom queries:
title:wm_user returns the WM_USER Windows message item, not all items that reference the WM_USER token.
title:wm_u* returns all items (Windows messages probably) whose name starts with WM_U*.
value:1024 AND title:wm_* returns all items (Windows messages probably) whose name starts with WM_U* and value is 1024. Note AND must be UPPERCASE for Lucene's to understand it as an AND operator.
value:"00000002-0000-0000-C000-000000000046" returns the IMalloc IID guid value.
