Possible to call a javascript script or function (w/ arguments) from a macro?

[lechristophe]

Hi,

I'd like to know if it is possible to call some javascript from a macro in
ImageJ. What I want to do is call the javascript, passing some arguments to
it (like a filepath), let it run, and return to the macro for further
processing. How should I proceed ?

Thanks for your help,

Christophe

Hi Christophe,

Did you see the eval("script", javascript) method?

Hi Curtis,

I have seen it, but how to pass an argument to the script? Plus, I'd prefer
to keep the javascript as a separate file because it is used outside the
macro too.

Thanks,

Christophe

Hi Christophe,

You could pass args using string concatenation; e.g.:

    eval("script", "print(" + myVariable + ")");

OK, apparently the "runMacro" command can run JavaScript, too:

    runMacro("/Users/curtis/Desktop/hi.js");

Where the contents of that file are:

    IJ.showMessage("Hello!");

I figured that out by trying it with Plugins > Macros > Run with the Macro
Recorder active.

Regards,
Curtis

You can call a JavaScript file and pass it an argument using the runMacro(path,arg) macro function. For example, the macro

     rtn = runMacro("test.js", "string argument");
     print("return="+rtn);

outputs

    arg=string argument
    return=this is the return value

when the file "test.js" (assumed to be in the Image/macros folder) contains

    print("arg="+getArgument());
    "this is the return value";

The JavaScript code retrieves the argument by calling getArgument() and the value of the last expression evaluated ("this is the return value") is returned to the calling macro.

Thanks Wayne, that is exactly what I was looking for!

Hi Wayne and all the ImageJers,

The runMacro(path, argument) command works fine to call a javascript via
its path from a macro. I'm now trying to do the same from a javascript,
i.e. calling a javascript (as a file with its path) from a javascript.

I used the following method which works with a js file on a Mac (OSX 10.9,
Java 1.6) :
IJ.runMacroFile(path, argument);

but on a PC (XP, Java 1.6), the argument isn't passed to the second
javascript and I get an error about the string litteral not being
terminated (in french, so I'm not sure about my translation).

What do I do wrong? Is there a better way to call a javascript as a file
from another javascript properly?

Thanks for your help,

Christophe

Dear Wayne,

After fiddling with Fiji installs to be sure that I have exactly the same
Fiji on both machines (with ImageJ 1.48t), I can confirm that the error
happens on PC and not on Mac (both with Java 1.6, the _24 bundled with Fiji
on the PC and the _65 on OSX).

On the mac the runMacroFile() command works ok, and on the PC I get:
Error: unterminated string literal (<Unknown source>#1) in <Unknown source>
at line number 1
and it looks like the argument isn't passed to the target javascript.

Thanks for your help,

Christophe
