I have complex nesting include directives. Sometimes the same file included twice. But this leads to errors. What is the best solution for this problem when file contains macroses and when it doesn't?
Currently I use

Code:

if ~defined file_inc
file_inc_fix:
file_inc fix file_inc_fix ;fix requires less memory than equ
;actual code...
end if

when file doesn't contains macroses.

Read the answer to fourth question in the FAQ and the section 2.3.7 of the manual (I feel like deja vu).

As for your particular problem, this macro will include each file only once, but only if the path given for such file is exactly the same each time (it's case sensitive):

Code:

macro includeonce path
{
 file@include equ path
 match head path tail,files@included
 \{ file@include equ \}
 match head path,files@included
 \{ file@include equ \}
 match file, file@include
 \{ include file \}
 files@included equ files@included path
}

PS. Do not overuse FIX directive - it is no longer to widely used, the section 2.3.7 might explain to you, why.

Thanks for this macro idea. It can be improved (if necessary) a little:

Code:

macro includeonce [path]
{
reverse
 file@include equ path 
forward
 match head path tail,files@included 
 \{ file@include equ \} 
 match head path,files@included 
 \{ file@include equ \} 
 match path tail, files@included
 \{ file@include equ \}
 match path,files@included
 \{ file@include equ \}
common
 match file, file@include 
 \{ include file \} 
forward
 files@included equ files@included path 
}

for using as includeone "real path","mirror1","mirror2"
PS When fix disappear from fasm syntax I manually execute "fix fix equ" command for my source files Wink
