The second file below will result in a "</w> Syntax Error" as shown at This has been a problem since 2018.11. The files render correctly with 2018.9. The problem seems to be the comment line in the first file. Removing it causes the second file to render correctly.

Note it still remains broken with 2019.4. Thx.

The error shown on the command line is

Thanks for the feedback.

This should be fixed in last beta

Tell us if it's not working for you!
commented Apr 20, 2019 by rd27 (460 points)
Yes, that fixed it. Thanks!

Actually, I found another case. The following works correctly in 1.2018.9, but gives the "</w> Syntax Error" in 1.2019.5beta17 and 1.2019.4.

We are currently moving to a new preprocessor implementation (see )
So we do not want to spend to much time on some code that will be soon removed.

Since this new one is going to be the default one, would it be possible that you use it for now (you just have to add !preprocessorV2 at the begining of your diagrams).
Your example indeed seems to work with the V2 preprocessor.

And this way, you could beta-test the new preprocessor.

What do you think about it ?
commented Apr 24, 2019 by rd27 (460 points)
Adding it does handle that case.

One challenge in using I have found though is if  !preprocessorV2 is in an included file I get a red Syntax Error. So I forced to switch to !includesub in many places I was using !include.

I also can't seem to add !preprocessorV2 as a default config in the IDEA plugin -

fyi that "default config in the IDEA plugin" goes to net.sourceforge.plantuml.SourceStringReader as 'List<String> config' param

This !preprocessorV2 is really a temporary thing.
So in last beta we have enable the new preprocessor by default.
This way, you can test it directly. Thanks!

FYI, With 1.2019.5 adding !preprocessorV2 via --config seems to cause a Syntax Error (while adding it in the *.puml fine does not). Not sure how long you plan !preprocessorV2 to be around.
