dotnet/roslyn

The .NET Compiler Platform ("Roslyn") provides open-source C# and Visual Basic compilers with rich code analysis APIs.

@bernd5

no they are from roslyn - that is right

timiil

@timiil

so , how can i write some anti human reading CodeFix rule ?

Bernd Baumanns

@bernd5

CodeFix is more than you need - a CodeFix adds some VS integration code

timiil

@timiil

oh, sounds bad. sounds that related by IDE, but not dotnet CLR

Bernd Baumanns

@bernd5

you could write a simple console app which loads the original source and produces "obfuscated" source which is than compiled to IL via the normal build pipeline

Yes, CodeFixes are IDE related - but what you want is not IDE related

timiil

@timiil

thanks for your kindly reply, a lot of knowlege knowed toninght and i should keep learning more

Bernd Baumanns

@bernd5

When you write your obfuscator you have to care about e.g. nameof() and reflection

because those names would change, too.

If you need further help - please ask.

timiil

@timiil

sure , very thanks :)

Yair Halberstadt

@YairHalberstadt

@timiil most obfuscators work with raw IL. They already exist so not sure why you would roll your own

timiil

@timiil

one reason is , IL changing this very hacking, and the opensource solution is so few amount.

Yair Halberstadt

@YairHalberstadt

Modifying IL is much safer, since it's easier to know what's safe to change and what's not.

Bernd Baumanns

@bernd5

yes - on IL level getting all semantics is quite complicated

but renaming locals would be very simple for example

Yair Halberstadt

@YairHalberstadt

For example you might rename an internal method named GetEnumerator and break a foreach.

timiil

@timiil

the second reason is , i think we have the source code, so if we use some skillful rewrite rule onto the sourcecode, and then build from roslyn, that sounds is very ...Nature

Bernd Baumanns

@bernd5

@timiil should the produced assembly be usable by other assemblies?

timiil

@timiil

who is behind 'dotnet build' ?? is 'MSBuild' or 'roslyn'

Bernd Baumanns

@bernd5

both 😃

MSBuild calls roslyn

timiil

@timiil

@timiil should the produced assembly be usable by other assemblies?

yes, that is exectly what i thinking on.

Bernd Baumanns

@bernd5

Than GetEnumerator would break not only on source level - but on IL level, too.

timiil

@timiil

and as we know, we even have opensource dotnet decomplier

Bernd Baumanns

@bernd5

You mean ILSpy?

timiil

@timiil

so , the pluzzle may be , decomplie -> rewrite source text -> complie on the air -> use it ?

Bernd Baumanns

@bernd5

not really

decompiling is quite hard

timiil

@timiil

https://github.com/icsharpcode/ILSpy

yes , sir

Bernd Baumanns

@bernd5

Some symbols can't be represented as regular csharp code

timiil

@timiil

yes , your are right. that maybe not 100% perfect

Bernd Baumanns

@bernd5

you loose (some) data after compilation

timiil

@timiil

@bernd5 i found https://github.com/JosefPihrt/Roslynator may be fun for CodeFix testing in command line

@frozenprakash

does anyone know where is the proposal for Property extension in C#?
Presently we only have function extension

Like string.CountNew rather than string.CountNew()

CyrusNajmabadi

@CyrusNajmabadi

Currently, it's rolled into:

dotnet/csharplang#5497

Chandraprakash

@frozenprakash

Wow, Thanks for the link man

CyrusNajmabadi

@CyrusNajmabadi

sure :)

timiil

@timiil

how about the 'left assigment expression attribute' ?? any one have the same idea ?

var btnYes = ControlFactory.Create<Button>();          //the method has know that the assigment expr is 'btnYes' so give it to  the Name porperty

CyrusNajmabadi

@CyrusNajmabadi

timiil

@timiil

the 'Caller Expression Attribute' give us the expr in the argument; i am looking for a way to know what is the 'Left Assigment Variable Name'

CyrusNajmabadi

@CyrusNajmabadi

yeah, there's nothing for that

also, it doesn't really feel like a well-formed operation

consider something as basic as: Foo(ControlFactory.Create<Button>())

there's no 'left assignment variable name'

timiil

@timiil

can we just 'home made' an attribute for this ? any idea or suggestion ?
