I am currently working on using json strings as input for my RAP generator tool.
Here I ran into the problem that I had to provide a (very) long json string as an input for a class that is run as a console application.
But also when using a simple json string such as this one (taken from Wikipedia) it is not possible to use cut & paste to work with it in ADT.
… unless you know which settings you have to change for your ABAP editor in ADT.
From the menu choose Window –> Preferences and there ABAP Development –>
Editors –> Source Code Editors or you search for source code editors in the Preferences dialogue.
Here you have to activate the check box Escape text when pasting into a string literal.
When you now use cut and paste and paste a long string, a json string or even an xml string to your source code within the placeholders for a literal
json_string = ''.
all strings will be wrapped automatically
