#define LASS_STRINGIFY

(

iA

)

LASS_STRINGIFY_IMPL(iA)

convert to string at preprocessor time.

Definition at line 62 of file common_macros.h.

Referenced by lass::num::NumTraits< char >::name().

#define LASS_CONCATENATE	(	iA,
		iB		)	LASS_CONCATENATE_IMPL(iA, iB)

concatenate two words at preprocessor time.

Definition at line 68 of file common_macros.h.

#define LASS_CONCATENATE_3	(	iA,
		iB,
		iC		)	LASS_CONCATENATE_3_IMPL(iA, iB, iC)

concatenate three words at preprocessor time.

Definition at line 74 of file common_macros.h.

#define LASS_BREAK_HERE   __asm__("int3")

user breakpoint

Definition at line 81 of file common_macros.h.

#define LASS_UNIQUENAME

(

iPrefix

)

LASS_CONCATENATE(iPrefix,LASS_LINE)

create a unique name based on a prefix and line number

Definition at line 93 of file common_macros.h.

#define LASS_FILE   __FILE__

current file

Definition at line 102 of file common_macros.h.

#define LASS_LINE   __LINE__

current line (stringified!)

Definition at line 107 of file common_macros.h.

#define LASS_FUNCTION   "??"

current function

Definition at line 118 of file common_macros.h.

#define LASS_EXECUTE_BEFORE_MAIN

(

x

)

LASS_EXECUTE_BEFORE_MAIN_EX(lassDummyName, x)

Executes code before the main has actually begun.

The macro relies on line numbers, so only one LASS_EXECUTE_BEFORE_MAIN per line!

Definition at line 151 of file common_macros.h.

#define LASS_EXECUTE_BEFORE_MAIN_EX	(	iPrefix,
		x		)

Value:

namespace \
    { \
        inline bool LASS_CONCATENATE( LASS_UNIQUENAME(iPrefix),func ) () \
        { \
            x \
            return true; \
        } \
        const bool LASS_CONCATENATE( LASS_UNIQUENAME(iPrefix),var ) = \
            LASS_CONCATENATE( LASS_UNIQUENAME(iPrefix),func ) (); \
    }

Same as LASS_EXECUTE_BEFORE_MAIN but with an additional parameter that let's you specify the used prefix.

Mmmh, let's use this as implementation of LASS_EXECUTE_BEFORE_MAIN :)

Definition at line 157 of file common_macros.h.

#define LASS_NOTE

(

iMessage

)

message(LASS_FILE "(" LASS_STRINGIFY(LASS_LINE) "):\n[LASS BUILD MSG] " iMessage)

pragma for leaving notes in build window

Definition at line 175 of file common_macros.h.

#define LASS_TODO

(

iMessage

)

message(LASS_FILE "(" LASS_STRINGIFY(LASS_LINE) "):\n[LASS BUILD MSG] *** TODO: " iMessage " ***")

pragma for leaving todo notes in build window

Definition at line 182 of file common_macros.h.

#define LASS_FIXME

(

iMessage

)

message(LASS_FILE "(" LASS_STRINGIFY(LASS_LINE) "):\n[LASS BUILD MSG] *** FIXME: " iMessage " ***")

pragma for leaving fixme notes in build window

Definition at line 188 of file common_macros.h.

#define LASS_UNUSED

(

x

)

x

tell the compiler that some variable may stay unused.

Some compilers throw warnings at us if a variable stays unused. Often this is a good thing, but sometimes that's exactly what we want. This macro will attempt to avoid the warning (as long as the compiler suports such an attempt).

  int LASS_UNUSED(foobar) = 0;
