I don't see the need in CreateLegacy/CreateExtended constructors as far as backward compatibility is maintained (it is the case as far as I understand). Just commit your Create constructors refactoring and document the changes (and update release notes). -- Best regards, Maxim Ganetsky mailto:gan...@narod.ru -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

This syntax is extended only for now, in a year it will be perceived as pretty much standard, so such constructor division (Create/CreateExtended/CreateLegacy) will itself be considered a quirk. ;) Anyway, we can consider it as an advanced feature which requires users to study deeper.

Now there is CreateLegacy() to make it easy and intuitive to use. The same way a new CreateExtended() would make the new syntax easier to use. Such a constructor is handy and intuitive especially when code completion is used. A user sees alternative constructor names right away. A sign of an intuitive well designed API is that you can select methods and properties etc. with code completion by their names without referring much to documentation. At least you then get an idea of what to search from the documentation.

You totally lost me here. IMHO there is no need for CreateExtende or similar new constructor. THis is what we currently have. TMask: constructor Create(const aMask: String; aCaseSensitive: Boolean; aOpcodesAllowed: TMaskOpCodes); virtual; overload; TMaskWindows: constructor Create(const aMask: String; aCaseSensitive: Boolean; aOpcodesAllowed: TMaskOpCodes; aWindowsQuirksAllowed: TWindowsQuirks); TMaskList: constructor Create(const aValue: String; aSeparator: Char=';'; CaseSensitive: Boolean=False; aOpcodesAllowed: TMaskOpCodes=MaskOpCodesDefaultAllowed); TMaskListWindows: constructor Create(const aValue: String; aSeparator: Char=';'; CaseSensitive: Boolean=False; aOpcodesAllowed: TMaskOpCodes=MaskOpCodesDefaultAllowed; aWindowsQuirksAllowed: TWindowsQuirks=WindowsQuirksDefaultAllowed); reintroduce; These __are__ the extended constructors for aal the fancy new/extended stuff. They are called by all the other constructors that only have the old parameters. So we have backwardscompatibility and extended capability just with all constructors named simply Create. -- Bart -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

The "default" constructor is the one with the TMaskOpcodes (/TWindowsQuirks) parameters. To be even more backwards compatible, mocRange should be disabled as well. I'm a bit reluctant to do so, as having ranges is quite an improvement over the old implementation (which had only sets). Possible problem is the '-' inside a range: this would be no problem in old code, but can raise exceptions in the new code. -- Bart -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

The Create constructors would then behave like CreateLegacy now. The extended syntax would have another constructor. I was pondering this same topic in an earlier post.
