Server dies when trying to autocomplete SIUnits package #13

Closed CSchoel closed 5 years ago

CSchoel commented 5 years ago

When I add SIUnits to my code, the Mo|E-Server dies with a StackOverflowError.

MWE:

model Foo
  Modelica.SIunits.Time t;
end Foo;

Error Message:

java.lang.StackOverflowError: null

Should be fixed in 0.7.2. Actually a omc-api error caused by an ambiguous regular expression. We should definitely implement a basic modelica parser. At least for nested expressions, like Arrays or records.

It doesn't crash with a StackOverflow anymore. Some times the parsing takes too long so the Future is killed before its completed.. :see_no_evil:

We do need a parser, not regular expressions!
