    How does SourceTree and Github Desktop compare?

    Declared: TEnum = (plough, foo, bar, wtf) Test order: [wtf, plough, bar, foo] Looping an Enum Set 1 wtf 5 plough 9 foo 14 bar Looping an Enum Array 1 wtf 5 plough 14 bar 9 foo Press Enter: You are right, @Stefan Glienke -I am so logging off now 😄
  4. Lars Fosdal
    Wow, I didn't notice that! And it is not related to declaration order, nor ordinal value. That is a bit disturbing.
  5. Lars Fosdal
    The inconsistent behavior between the two variations of enumerated types is another pitfall, I guess.
  6. Lars Fosdal
    Or pitfall 😛
  7. Lars Fosdal
    Off-topic - I actually do reverse for in loops with a custom enumerator which starts on top and decrements instead.

    @Uwe Raabe Are you saying that for ix := Low(Array) to High(Array) do begin v := Array[ix]; is predictable - while for v in Array is not predictable ?
  9. Lars Fosdal
    I wonder how it behaves if I have a set enumerated type with hard coded ordinal values? Edit Change the declaration to TEnum = (plough = 5, foo = 9, bar = 14, wtf = 1); Now the set behaves just like the array.
  10. Lars Fosdal
    Except it is rare to see a TList or any other object structure "hardcoded" in plain sight, while arrays of simple types are not hard to read nor uncommon.
  11. Lars Fosdal
    For a list or any other object enumeration interface, I'd agree - but for an open array or a TArray?
  12. Lars Fosdal
    It is pretty quick to miss that "detail". They look the same, so unless you really pay attention to the type element type - there is little to tell you that you are looking at a set and not a list.

    Code that looks correct, and appear to compile alright, but which doesn't execute well. Can you spot the error? See my blog post for a link to a SCCE. var Handler: THandlerClass; hType: THandlers; begin Broker.Clear; for hType in [foo, bar] do begin case hType of foo: Handler := TFoo.Create; bar: Handler := TBar.Create; end; Broker.AddHandler(Handler.OnHandle); end; end; https://larsfosdal.blog/2019/02/08/delphi-pitfalls-of-anonymous-methods-and-capture/

    Pitfalls of Anonymous methods and capture

    Lars Fosdal replied to Lars Fosdal's topic in RTL and Delphi Object Pascal

    Close, its a Self-Contained Compilable Example, sometimes also called a SSCCE, i.e. a Short SCCE. I'll rewrite the article for better readability.

    Is this related to databases?

    Pitfalls of Anonymous methods and capture

    Lars Fosdal replied to Lars Fosdal's topic in RTL and Delphi Object Pascal

    There is one, but you "wasn't about to download some project from a file sharing site" (i.e. a zip file with source code from Google Drive)

    @David Heffernan If you added me to your Ignore list here on DP, I would be totally fine with that.

    Lars Fosdal replied to Lars Fosdal's topic in RTL and Delphi Object Pascal

    Which is why my post specifically pointed out that there is a link to the SCCE in the blog post?

    Pitfalls of Anonymous methods and capture

    Lars Fosdal replied to Lars Fosdal's topic in RTL and Delphi Object Pascal

    Yes, the examples leak. I didn't want to clutter it up with too much housekeeping code. Thank you, Uwe, for enlightening me on variable vs value capture. IMO, the compiler could need a hint or warning if a variable capture happens in a loop, because it is really easy to overlook. I use a number of variations on this to do dependency injection. It really helps with avoiding pulling too much project specific code into general code and keep the libraries isolated from each other. This code in particular is part of a web server that (now correctly) supports a configurable collection of JsonRPC protocol handlers. The web server knows nothing about Json, and the protocol handlers knows almost nothing about http.

    Anybody else see the same?

    10.2 Tokyo unable to report issues from within the IDE

    Lars Fosdal replied to Lars Fosdal's topic in General Help

    What do we know about the state of 10.3 Rio in this context?
  22. Lars Fosdal
    Does anyone know if there are existing libs out there that can extract this across all FMX platforms? - Current user - Device name
  23. Lars Fosdal

    Cross-platform discovery of device name and user name?

    Lars Fosdal replied to Lars Fosdal's topic in Cross-platform

    https://developer.android.com/training/id-auth/identify Would this be usable to get some sort of username / identity? Perhaps there is something similar on iOS as well?

    Request for advice: FireMonkey and Frames

    Lars Fosdal replied to Lars Fosdal's topic in Cross-platform

    So basically just like for VCL. Nice.

    Request for advice: FireMonkey and Frames

    Lars Fosdal replied to Lars Fosdal's topic in Cross-platform

    @Rollo62 Can you exemplify how you "load via runtime into TRectangles" ? In my current app, I want to instantiate the frame onto a TTabItem.
