For single-indexed containers, you can use a generic TDictionary, for instance one of these:
Reminder to self: check out if there is a generic version of [WayBack] A multi index container: TIndexedStore – Martin C Harvey’s Software Pages anywhere.
Edit 20191220 (thanks Thaddy!) article moved to [WayBack] A multi index container: TIndexedStore – Martin C Harvey’s Pages.
For instance as part of:
The original library has source code in a [WayBack] zip file.
Edit 20191220 (thanks Thaddy!) download moved to [WayBack] IndexedStore.zip.

From a long time ago, but recently I needed them again.
Note the .NET side is much much harder Revisited from the .NET side: Why doesn’t WINWORD.EXE quit after Closing the document from Delphi? (via: Stack Overflow).

Reminder to self: split off the user settings from a Delphi .dproj so only the non-user settings get into your version control system.
Some of you are probably already using my DprojNormalizer plugin for Delphi, which tries to reduce the unwanted differences disturbing your version control system. It does this by forcing a dedicat…
So what about them?
DprojSplitterhandles the current build configuration and current platform. In addition these settings are handled, too (found inCommonOptionStrs):
sDebugger_RunParams,
sDebugger_RemoteRunParams,
sDebugger_HostApplication,
sDebugger_RemotePath,
sDebugger_RemoteHost,
sDebugger_EnvVars,
sDebugger_SymTabs,
sDebugger_Launcher,
sDebugger_RemoteLauncher,
sDebugger_IncludeSystemVars,
sDebugger_UseLauncher,
sDebugger_UseRemoteLauncher,
sDebugger_CWD,
sDebugger_RemoteCWD,
sDebugger_RemoteDebug,
sDebugger_DebugSourcePath,
sDebugger_LoadAllSymbols,
sDebugger_LoadUnspecifiedSymbols,
sDebugger_SymbolSourcePath

As I will probably need this one day: [WayBack] How does one convert a Delphi enum to a JSON value, with different specific values? – CHUA Chee Wee – Google+:
eg,
TEnum1 = (test1, test2, test3)
TSomeClass.FEnum := test1;When converted to JSON, I’d like to see maybe
{"Enum": "Value1"}instead oftest1and
test2to"Godzilla",test3to"Tiburon"
The solution is in his repository: github/chuacw/EnumJson:
After initially suggesting to look into [Archive.is] Serializing User Objects – RAD Studio, he based his solution on a set of clever tricks circumventing Delphi compiler limitations and bugs:
TEnumInterceptor<T> from [Archive.is] Data.DBXJSONReflect.TJSONInterceptor and put the conversion logic in thereTEnumInterceptor<T> because of a compiler limitation and bugData.DBXJSONReflect.JSONReflectAttributeLater he extended the solution to include sets in additions to enums: [Archive.is] Persisting enumeration and sets to JSON – Chee Wee’s blog: IT solutions for Singapore and companies worldwide (via [Archive.is] Made my JSON interceptor demo public. Now you can save your enum and sets to JSON, with customized output to boot! – CHUA Chee Wee – Google+)
Clever!
Hopefully this got Lars Fosdal some ideas to solve [WayBack] JSON in Berlin – Can I persuade TJSon to treat “params” as it was a string and not an object for the TJsonRPC class? – Lars Fosdal – Google+
Enums with Delphi and their mapping is a repeating topic, see for instance [WayBack] What’s the easiest (ie., least coding) way to map an enum to a const string and vice versa? (Can attributes be used on enum values yet?) eg., type TMyColor… – David Schwartz – Google+
It shows how much the Delphi language is in need of language enhancements as right now there are way too many open source libraries struggling with the same issues each working around them or providing solutions in slightly different way.
Three things immediately come to mind:
Some examples of libraries providing enumeration support:
TEnum class with static methodsTEnumeration class with static methodsEnum.Wrapper unit with various records mimicing .NET behaviour based on David’s workSome more thoughts from a different perspective: [WayBack] What’s New in Edge Rails: Active Record enums

Good to know this as the Structure View sometimes lets me down: modify the PageIndex position as it is less stable than the Object Treeview in Delphi 7 and below.

Reminder to self to check out when [Archive.is] FormatSettings global variable of type [WayBack] TFormatSettings was deprecated as it was only documented as of Delphi 2010 but available much much earlier.
