Goal

Create a few useful additions to Eclipse CDT. Current target: static code checkers.

a.h:
#ifndef A_H
#define A_H
int foo();
#endif

b.h:
#ifndef A_H
#include "a.h"
#endif

int bar();

Add unit tests for included headers that are in the 'Includes', not part of the 'Source Location' list.

Includes:
- Check if included header is used
- Check if a transitive header include is done (A includes B, B includes C. A needs C, but not B).
Better solution for includes:
- Go over all the types in the file, checking in which file they are defined. Propose 'add include' for the files in which they are defined.
- Go over all the types in the files, checking in which file they are defined. All the files that do not have any types referenced, are marked as not needed.
- The above two checkers can be run, resulting in a 'clean up includes'.
Check if header contains proper internal header guards.
Check if a function returns a local variable.
Check for statically created arrays being compared with NULL: http://stackoverflow.com/questions/3857229/check-if-c-array-is-null
Check for variable declaration within switch statement: http://stackoverflow.com/questions/92396/why-cant-variables-be-declared-in-a-switch-statement

Doxygen in CDT (https://bugs.eclipse.org/bugs/show_bug.cgi?id=180141)
- ContentAssist/Hover: org.eclipse.cdt.ui.text.c.hover.ICEditorTextHover -- ITextHover -- CSourceHover -- AbstractSourceViewerInformationControl
- Automatically format '/**' comments as Doxygen (generating return value and such)
  - DoxygenMultilineAutoEditStrategy
Hiding the top comments if they contain 'Copyright' or 'Disclaimer' statements

Quickfix: move variable into method (for example if only used as input variable for that method):

int a; someFunction(a);

void someFunction(int a) {
    //use a
}

Becomes:
someFunction();

void someFunction() {
    int a;
    //use a
}

char* concatenation should cause a warning if it happens in an array of char*'s. Example:

char* foo[] = { "aaaaaaaaaa", "bbbbbbbbbb" //Give warning here "cccccccccc" };
