Using JSON files in Macros

[Kirmse, Robert]

Dear ImageJ List,
I have a question regarding the use of JSON files.

I would like to use a JSON file for storing settings/parameter for a macro.
However I am not sure how to use the variable in the actual macro once I read it.

So the way I tried to set it up is the following


javascript file that reads the JSON with.

...
function read JSON() {
var settings = JSON.parse(IJ.openAsString("pathToFile\\inputs.json"));
"some more code"
return(settings)
}

--------------------
and then my actual IJM file
"some code"

javacode = File.openAsString("pathToFile\\JSON_Read2.js");
settings= eval("script",javacode);


that only give the message "object array" in the log file, when I try to access settings.
I tried storing the retrieved JSON content in different variables that i tried to return but was not successfull.

I am wondering if there is an elegant way to actually get the JSON content and make them
available for the imageJ macro.

Thank you in advance for any hints

Best
Rob

Hi Rob,

Have you considered using a full-featured scripting language such as
JavaScript, Groovy, etc.? Then you would not have to work around
limitations of the ImageJ macro language. For details, see this page:

It could also help move the discussion forward if you can describe _why_
you want to do this. What are you trying to accomplish?

Regards,
Curtis

Hi Curtis
Thank yes I have considered this and for new projects I will definitely do this.

However I was also using existing macros that I would like to avoid re-implementing in another scripting language.

As to the why - the macros I am using are supposed to run in a batch/headless mode and the input parameters are supplied
through JSON files. This is in a broader environment that is why the json files are a fixed parameter at this point.

Thanks
Best
Rob
