When trying to copy code, if the selected text contains the def line, nothing is put on the clipboard. This led me to believe copy/paste was not working because I was trying to copy a script from one screen to another and was using ctrl A to select the whole script.
If this was a purposely included feature, it is a bad one in my opinion.
Where are you seeing this behavior? I can only replicate it on ignition defined def statements.
This is Ctrl + A on a schedule script.
Ctrl + A on a script in my library:
In the new editor in 8.1.18, ctrl+a once will select the "user authored" portion of code, and a second time will select all code including the definition. Both will copy to the clipboard cleanly.
Specifically when copying custom method code from scripts attached the top level (window level, not root)
I have reproduced this many times. Any time the def statement is in the copied text, the copy does not happen. I am going to assume this is the case no matter what the custom method is attached to.
I figured this would be fixed in a future version. Thought I would bring it up just in case. Thanks for the response. Just trying to keep my sanity somewhat intact!
