Just a heads-up: There's been a fair amount of activity on Demangle.cpp since December, and talk of "new mangling". Maybe preparation for Swift 4?

Sigh. I was just about to integrate your great Swift-based demangle code into my Swift logging module, now I fear that could soon be a wasted investment.

(But I still think it's marvelous that you did this work.)

Hi Matt,
Is CwlDemangle supports Swift 3?

For example this symbol:

"_T0s14StringProtocolP10FoundationSS5IndexVADRtzrlE10componentsSaySSGqd__11separatedBy_tsAARd__lF"

demangles into this when you call SwiftSymbol.print() on it:

"(extension in Foundation):Swift.StringProtocol<>.components(separatedBy: A\u{1}) -> Swift.Array<Swift.String>"

If you just dump this string as part of a json serialization process, then it will be invalid json and cannot be parsed by other json deserializers.

In swift you would represent the U+0001 char as "\u{1}". You can see a list of unicode characters here: https://en.wikipedia.org/wiki/List_of_Unicode_characters

Hello

We are using your demangle swift code in our project to print stack traces in a little bit more readable way.

Unfortunately this mangled name is crashing Demangle.swifton printing its name, after calling SwiftName.description with following string passed to demangleSwiftName to create SwiftName instance in the first place:

_TFFFFC9Le_Figaro11DataManagerP33_4BF0F705F2DC93973E68326EF6A0FFBA16getSingleArticleFTGSqSS_13articleSourceGSqSS_10articleUrlGSqSS_17completionHandlerGSqFT_T__12errorHandlerGSqFGSqPs5Error__T___T_U_FGSqP__T_U_FCSo22NSManagedObjectContextT_U_FT6resultGSqP__5errorGSqPS1____T_

as string parameter.

Swift 3.0, Xcode 8.0

It would be nice to be able to include this as an external dependency using swift package manager.

this is a greate job by translate it form c++ to swift!
I want demangle swift symbols in server, my server code is java [\sad],I do not good at java develop.do you know anywhere has java implement?

Sorry for the very weird question 😅

Is there a way to go back to the mangled version?

If for instance if I have a function:

Mangled:

$s6Module3FooC3bar3bazSayAA3BarVGSi_tF

Demangled:

Module.Foo.bar(baz: Swift.Int) -> Swift.Array<Module.Bar>

And if I want a specific part mangled back. For example for Swift.Int:

$sSiN

I'm not looking for anyone to fix this for me. I'm happy to implement it myself 🙃 .
Would just like some idea of how to change the code to accommodate.

My idea so far was to keep track of the area in the mangled string for a specific node in the AST and just store that, in the SwiftSymbol Object. But we still need to resolve how to mangle the module name back: i.e. how do I go from Swift.Array<Module.Bar> to $s[...]6Module3Bar[...]?
