IsMacro

[jj2007]

I thought that was simple: checking if e.g. printf is already defined or not. Any better ideas than what is posted below?

Code Select Expand

include \masm32\include\masm32rt.inc

IsMacro macro NewMac
  echo
  echo testing NewMac
  ifndef NewMac
% echo @CatStr(<## Line >, %@Line, <: NewMac not yet defined ##>)
  else
% echo @CatStr(<## Line >, %@Line, <: NewMac ALREADY DEFINED - Masm32 macro? ##>)
  endif
  tmp$ CATSTR <NewMac>, <(0)>
  is=0
  % FORC c$, tmp$
ifidn <c$>, <(>
is=2
endif
  ENDM
  if is
% echo @CatStr(<## Line >, %@Line, <: NewMac not yet defined ##>)
  else
% echo @CatStr(<## Line >, %@Line, <: NewMac ALREADY DEFINED - Masm32 macro? ##>)
  endif
ENDM

.code

start:
IsMacro printf
IsMacro Printf
IsMacro print
IsMacro Print
exit

end start

Output:
testing printf
## Line 28: printf ALREADY DEFINED - Masm32 macro? ##
## Line 28: printf ALREADY DEFINED - Masm32 macro? ##

testing Printf
## Line 29: Printf not yet defined ##
## Line 29: Printf not yet defined ##

testing print
## Line 30: print ALREADY DEFINED - Masm32 macro? ##
## Line 30: print not yet defined ##

testing Print
## Line 31: Print not yet defined ##
## Line 31: Print not yet defined ##
