[Wikidata-bugs] [Maniphest] [Commented On] T244046: Consider creating a Wikibase Property type for patterns

  A specific data/property type for regular expressions or patterns would:
  
  - ensure that the stored regular expressions or patterns are syntactically 
correct, in a similar way that quantity-type properties ensure that their 
statements are not paragraphs, something from which all implementations, tools 
and reusers would benefit;
  - introduce a specific input (interface) control in Wikibase (not 
WikibaseQualityConstraints) that could make pattern editing more friendly: 
monospaced text, warnings, colored brackets, and all the amazing features that 
the developers want to implement. :-)
  
  This does not solve the low-level security issues of each implementation 
(e.g., avoid running the regular expression "'; DROP TABLE important_things;").

  > Some technical issues … that are related to the lack of ability to manage 
regular expressions are described on T176312 
, T214378 
, T236150 
 and T240884 
.
  
  How would any of these be affected by a separate data type for regular 
expressions / patterns? The problem is the same: we still need to evaluate 
user-specified (untrusted) regular expressions safely; I don’t see what a 
separate data type would change here.
