Quartus II TCL: Analyze vhd files in a directory using quartus_map executable

Hello,

I would like to analyze specific vhd files in a directory, not all of the design files (as part of an incremental compilation flow).

I tried to use --analyze_file option of the quartus_map executable but it seems not to like a list as argument.

  
  ...
  set filename_list 
  if {} {
   ...
  } else {
   ...
  }

So i tried a foreach loop to execute the module for each file, it's working but it's redundant and slow.

Is there a better way to do it please?
