VerCompare() [v1.1.36+]

Compares two version strings.

Result := VerCompare(VersionA, VersionB)

Parâmetros

VersionA

The first version string to be compared.

VersionB

The second version string to be compared, optionally prefixed with one of the following operators: <, <=, >, >= or =.

Return Value

If VersionB begins with an operator symbol, this function returns 1 (true) or 0 (false).

Otherwise, this function returns one of the following to indicate the relationship between VersionA and VersionB:

• 0 if VersionA is equal to VersionB
• a positive integer if VersionA is greater than VersionB
• a negative integer if VersionA is less than VersionB

To check for a specific relationship between the two strings, compare the result to 0. Por exemplo:

a_less_than_b := VerCompare(a, b) < 0
a_greater_than_or_equal_to_b := VerCompare(a, b) >= 0

Remarks

Version strings are compared according to the same rules as #Requires.

This function should correctly compare Semantic Versioning 2.0.0 version strings, but the parameters are not required to be valid SemVer strings.

This function can be used in a sort callback.
