Is there a ULP dirty flag?

 

Just as a final note, below is my modification to check to see if a file

is writeable:

 

    //

    // A separate instance of Eagle will be invoked from the command line

    // to produce gerber files.  As such, it does not have access to objects

    // in this process's memory space and can only read from the disk.

    //

    // Therefore, it is imperative to make sure this board is saved

    before allowing

    // this program to continue.

    //

    string file;

    if(argv[1] != "saved") {

         // Get the file name out of the board.

         board(B) {

             file = B.name;

         }

 

         // Is it writable?

         if (system("test -w " + file) == 0) {

             // If so, save it.

             exit("write;\nrun camprep saved;\n");

         } else {

             // If not, give the user a chance to change his mind.

             if (dlgMessageBox("!<b>" + file + "</b>"

                 + "<p>The board file is not writable."

                 + "<p>CAM files will be built from last saved version.",

                 "&Continue", "&Abort") != 0) {

                 exit(0);

             }

         }

    }

 

Thanks for your input.

You could try this. - Run it from a board

It less graceful but it does the job.

You attempt to open your board file in 'append' mode and the OS protests

(Win in my case).

string MyFile;

if(board) board(B) {MyFile = B.name;

fileerror();

output(MyFile,"aF"){}

if (fileerror()){

     dlgMessageBox(";I tried to open the board file in append mode.\nI

assume the file is read only or locked\n\nThe ULP will exit");

   exit(1);

     }

else dlgMessageBox("Hooray!\nI can write to the file "); exit(0);     

}
