The response of http://www.plantuml.com/plantuml/uml to the script below is a blank page. No error message; just the blank page.
https://www.planttext.com/ answers quickly with an "empty" diagram. No warning or anything.
On my local PlantUML-installation it's processed in no time and outputs a correct svg-file.
Clicking the link returns of course an error. "MATLAB cannot link to this file or URL:
file:///h:/m/PiaRepos/m2uml/abcdefghij1234567890"
There seems to be an upper limit of the length of the string enclosed by [[ ]] - 180 characters or something like that. Or the limit might apply to the total line length.
Switching back to the user interface and an error message, "line length exceeds 200 characters something", would be nice.
