A repository with a hierarchy or modules referencing each other might not be a good idea

Posted by jpluimers on 2018/11/20

When creating a library of libraries where the libraries use parts of the other libraries creates a mess when organised as a repository with subrepositories having other subrepositories.

It might be better to have one big repository containing a suite of functionality. This is why darkThreading became part of darkGlass: [WayBack] Why no git submodules for the libraries it depends on? · Issue #1 · chapmanworld/darkThreading · GitHub:

You might want to maintain that suite as one big versioned repository, with a different means of structuring it than a tree of submodules. That way you can keep the more complex interdependencies between the parts you have now.

Example of the mess: [WayBack] Duplicate submodules with Git – Stack Overflow

Where does my git question go? – Programmers Meta Stack Exchange

Posted by jpluimers on 2018/11/20

StackOverflow / StackExchange is growing too large:

You’ve got a question about git. Its not uncommon, lots of people have questions about git. But where should the question be asked?

Reminder to Self: check if NameOf has been implemented yet

Posted by jpluimers on 2018/11/20

It’s been a wish for a very very long time: to get the name of an identifier as a string in Delphi:

For now the best one can do is either using an Assert and catching the exception (it gets you the unit name, source file name and source line number) in the links below, or using debug symbol information (like a MAP or TDS file) mentioned in the StackOverflow questions above.

C# has had a  [WayBack] nameof for many years now that is evaluated at compile time: [WayBackc# – Is nameof() evaluated at compile-time? – Stack Overflow.

There is a request RAD Studio – RSP-13290: NameOf(T) compiler (magic) function in Quality Portal by Horácio Filho about 3 years ago quotes below.

Since it took the C# team about 3 years after the original [WayBackAdd nameof operator in C# – Visual Studio request, I wonder how fast the Delphi team is.

NameOf .NET-like compiler magic (intrinsic) function would eliminate a lot of hand-written exception messages from several units.

C# 6 introduced nameof operator to obtain the simple (unqualified) string name of a variable, type, or member.

With the current Delphi implementation, after changing variables name we have ot change the related exception message as well. Putting variables name in the code is not a good practise, and is here that NameOf taking place saving tons of lines of code. As the result of NameOf(T) function (if so) is evaluated at compile time (according to the C# implementation – http://stackoverflow.com/a/26573179) we need a help from compiler or it could be achieved using RTTI.

There is a discussion on Google+ community [WayBackhttps://plus.google.com/+StefanGlienke/posts/AsGHSLF4rTX.
The function could be designed as
NameOf(x: Identifier)
following the same (or similar) warranties C# provides.

Using Assert:
