Bug ID: 152690
Summary: Operator Like handles "!" in character set wrong, when
"!" is not the first in the set
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: difficultyBeginner, easyHack, skillCpp
Severity: normal
Priority: medium
Component: BASIC
Assignee: [email protected]
Reporter: [email protected]
LibreOffice supports Like operator [1], when using Option Compatible or Option
VBASupport.
Consider this code:
Sub TestLike()
MsgBox "!" Like "[.!?]"
MsgBox "^" Like "[.!?]"
End Sub
In MS VBA, it produces "True" first, and then "False".
In LibreOffice, it produces "False" first, and then "True".
This is because character "!" should mean negation, only when it's the first
character in the group; in other positions, it matches itself.
Code pointer: function VBALikeToRegexp in basic/source/runtime/runtime.cxx,
which should only check for "!" immediately after "[", and not in other
positions.
