Text window name?

[Gabriel Landini]

Hi,
I am curious about this:
Below is the SineCosineTable2.txt macro from the IJ site, why does one have to
surround the title in "[ ]" to create the table and print to it, but use the
same string without "[ ]" to test whether it is open?

-------8<--------
  requires("1.38m");
  title1 = "Sine/Cosine Table";
  title2 = "["+title1+"]";
  f = title2;
  if (isOpen(title1))
     print(f, "\\Clear");
  else
     run("New... ", "name="+title2+" type=Table width=250 height=600");
  print(f, "\\Headings:n\tSine\tCosine");
  for (n=0; n<=2*PI; n += 0.1)
     print(f, n + "\t" + sin(n) + "\t" + cos(n));
-------8<--------

Thanks,

Gabriel

Hi Gabriel,

The name of the window is "Sine/Cosine Table" without the brackets.
But when passing a plugin argument string, you must place brackets
around argument values with spaces -- otherwise it would be
interpreted (in this case) as "name=Sine/Cosine" with "Table" as an
enabled boolean parameter. For print, according to the macro language
documentation, multiple arguments with commas are just concatenated
with a space between each, meaning you would have the same problem of
ambiguous window titling if brackets were not used. None of this is an
issue for window titles with no spaces.

I agree in theory, but not in practice :-)
Not sure if this is a bug, then:

This does not work in linux (it prints to the Log window instead):

//======================
f1 = "Test";
f2 = "["+f1+"]";

// --- to a table window
if(!isOpen(f1)){
  run("New... ", "name="+f1+" type=Table width=300 height=400");
  print(f1, "\\Headings:Filed1\tField2\tField3");
}
x=1;
y=2;
z=3;
print(f1,x+"\t"+y+"\t"+z);
//======================

But this does work (i.e. it prints to the Test table):
The difference is the [ ] in the table creation and the print statements. They
are both strings without spaces.

//======================
f1 = "Test";
f2 = "["+f1+"]";

// --- to a table window
if(!isOpen(f1)){
  run("New... ", "name="+f2+" type=Table width=300 height=400");
  print(f2, "\\Headings:Filed1\tField2\tField3");
}

x=1;
y=2;
z=3;

print(f2,x+"\t"+y+"\t"+z);
//======================

Cheers,

Hi Gabriel,

Ah, I should have read the macro documentation more thoroughly. From
the web site:

"Starting with ImageJ 1.38m, the second argument to print(arg1, arg2)
is appended to a text window or table if the first argument is a
window title in brackets."

So the situation with print is a special case. If the first argument
is something in brackets, it is interpreted as a file. Otherwise, it
is merely concatenated.

Note that your working macro still works if you change the f2 to f1 in
the "run" command (because "Test" contains no spaces).

I was not sure of why of this. It seems a bit convoluted, but perhaps there is
no other way of indicating what the argument means?

Thanks again,
