This release has been tested with Apache ActiveMQ 5.14.5, Apache ActiveMQ Artemis 2.0, OpenMQ 5.1.1 and RabbitMQ 3.6.9.

Starting with this release, the library requires Delphi 2009 or Free Pascal 3.0.2 (or newer), it is not compatible with non-Unicode versions of Delphi. The internal version numbers of all client libraries in the 2017.04 release is 5.0.0.

Regular expressions for missing parameter modifiers

[(;]\s*(\w*)\s*:\s\w*[sS]tring\W

This expression locates most candidates for a missing const modifier for string types.

[(;]\s*(\w*)\s*:\s*([I]\w*|\w*[sS]tring)\W

Same as above, also includes type names beginning with the letter I (coding convention for interface types).

Examples

 // no match
procedure Test(const Arg: string);

 // match
procedure Test(Arg: WideString); 

// no match
procedure Test(const Arg: string; var Arg2: WideString); 

// match
procedure Test(const Arg: string; Arg2: AnsiString); 

Tested with GExperts Grep Search, which does not support multiline expressions.
