<p dir="ltr">I am out of the office today, and will reply in more detail later, but just wanted to quickly add: the example Johannes wrote should work with the current master branch as well as the recent 2.0.0-beta-7.7 release. Specifically, it will work if you "Run Script" since the parameter parsing mechanism etc. is all already in place. It just doesn't work from the Script Editor yet since that tool needs some TLC still. As Johannes says, I am still actively hacking on scripting support.</p>
<p dir="ltr">Also note that you can inject a Context parameter then make a new ImageJ gateway object wrapping it to easily access services the same way the tutorials do. (I forget whether ImageJ gateways are injectable ATM but if not, they will be.)</p>
<p dir="ltr">Anyway, please let us know if you are unable to run such scripts.</p>
<p dir="ltr">Regards,<br>

Yeah, in IJ2 you have to use a context. The static functions of ImageJ 1.x<br>
do not allow you to insulate separate processes from each other. That<br>
leads to surprising results, e.g. when you try to put more than one<br>
ImageJ 1.x applet into the same web page: it simply won't work, ever.<br>

<br>
This is a work in progress right now, under heavy construction.<br>
Eventually, something like this will work:<br>
<br>
-- snip --<br>
# @StatusService status<br>
# @OUTPUT String greeting<br>
<br>
status.showStatus(1, 2, "In progress...")<br>
status.warn("This is a gentle warning")<br>
status.showStatus(2, 2)<br>
<br>
greeting = "Hello, world!"<br>
-- snap --<br>
<br>
In other words, your input and output parameters will be specified using a<br>
syntax similar to ImageJ2 commands' at the top of the script.<br>
<br>
Ciao,<br>
Johannes<br>
