replace Built-in Macro Function and *None*

[Soriano.Joaquim]

Hi everyone!!!
I'm learning imagej Macro programming and need help with an issue regarding the Built-in Macro Function: replace(string, old, new).
Whenever I want to replace a string containing "*None*", it wouldn't work.
Does anybody know what's going on?
I send you an example.

string0 = "red=*None* green=*None* blue=*None* gray=*None*";
print("string0:"+string0);
string1 = replace(string0, "red=*None*", "red=Ejemplo.tif-Red");
print("string1: "+string1);

Thank you very much in advance.

You need to check the Regular Expressions link in the IJ site associated with
"replace".

This seems to work:

string0 = "red=*None* green=*None* blue=*None* gray=*None*";
print("string0:"+string0);
string1 = replace(string0, "red=\\*None\\*", "red=Ejemplo.tif-Red");
print("string1: "+string1);

Cheers

Hello Joaquim,

You need to scape asterisks by using "\\*".

Your code will be something like this:

> string0 = "red=*None* green=*None* blue=*None* gray=*None*";
> print("string0:"+string0);
> string1 = replace(string0, "red=\\*None\\*", "red=Ejemplo.tif-Red");
> print("string1: "+string1);

You will obtain the following as output:

string0:red=*None* green=*None* blue=*None* gray=*None*
string1: red=Ejemplo.tif-Red green=*None* blue=*None* gray=*None*

Hope that helps!

Sincerely,

Juanjo.
