Hello PlantUML team,
With the version V1.2020.20, this is fixed, with this error message :
!$c=1 | 0
^^^^^
Parsing syntax error about |
or
!$c=1 & 0
^^^^^
Parsing syntax error about &
Then old short form: `&`, `|` or `!` are only for old preprocessor.
And the new preprocessing support only `&&` and `||` or `%not()`.
The documentation has been updated accordingly: See new §Boolean expression on Preprocessing page.
Thanks for yours works ,
Regards,
Th.
