12:47:57amoxI found only ssleay64.dll
12:48:09amoxWhere can I take the second dll?
12:48:31amoxCould someone help me?
12:49:37Araq_ping dom96
12:49:59Araq_use the 32 bit version for a start
12:50:09Araq_the 64 bit DLLs are broken for some reason iirc
12:50:22dom96hello amox!
12:50:33dom96yeah, usually better to use 32 bit DLLs
12:50:46dom96(make sure to use a 32 bit Nim compiler too though!)
12:53:40dom96Really wish there was a way to get more info about why a DLL load failed.
12:54:00dom96Araq_: I probably asked you about this already, but are there any improvements we could make?
12:55:04yglukhovAraq: regarding 3688. Whats wrong with it?
12:56:07amoxThank you! I'll try 32 bit

13:26:23Araq_yes
13:27:07Araq_we just need to release nimble without SSL support. fuck that bullshit.

15:16:34dom96just '-d:ssl' (not sure about the syntax for .nims

15:17:42dom96amox: Probably not where you should put it :)
15:19:03amoxbut it works
15:20:13dom96Sure, it's just nicer to have a directory somewhere for these DLLs. It just needs to be in your PATH IIRC.
15:20:24dom96or you can put it beside the .exe
15:21:07amoxyes I put it next to exe - it works too
15:23:21amoxbut I have cmd window opened too with GUI (nimx) http://prntscr.com/9me79s Can it be set up to run without cmd?
15:26:01amoxyglukhov is owner but he is away
15:31:27dom96Pass --app:gui to the compiler, might work

21:15:38krux02Araq_: I have a question about types for my development on getType
21:16:46krux02A generic type has in it's PType a member that is generic, all generic parameters, and the actual instanciation of the type.
21:17:19krux02since I return as an AST a bracked expression MyType[int,float]
21:18:01krux02I would like to keep the 'MyType' clean of the concrete instance of MyType[int,float]
21:20:32krux02so that a transformation of MyType[int,float] to MyType[float,int] has no preblems giving me the implementation of that.

21:50:55Araq_the VM shouldn't perform generic instantiations
21:50:58krux02pita? like food?
21:51:13Araq_instead you should generate an new AST and let the compiler do its job
21:51:16mat4hello
21:51:56krux02ok, then it would be better to prevent AST changes
21:52:18Araq_getType() is only for reading types, not for type construction
21:52:28Araq_because type construction is too hard.
21:52:44Araq_people will provoke compiler crashes all over the place
21:52:44krux02ok
21:53:31Araq_IME types are foundamentally harder to deal with than syntax trees and so we need to push people to use simpler alternatives
21:54:09krux02ok, then I should document it, that the result of getType should not be manipulated
21:54:36Araq_yes please
21:54:46mat4Araq_: What are these alternatives ?
21:55:02krux02ok
21:55:10krux02makes my job easier
21:55:11Araq_mat4: construct the type syntactically and let the compiler transform it into a type for you.
21:55:35Araq_it has to do that anyway to check for soundness
21:57:23krux02I am just thinking of what happens, if the result of getType get's used to create a function with that type as an argument
21:57:36mat4hm, I believe this approach should be obvious even the simplest
21:58:49krux02not that I know of any use of that, but I guess, because it can be done, it will be done.

23:39:45Araq_krux02: do you need to know this though?
23:40:38krux02Araq_: I came to the conclusion, that I need two functions, getType, and getTypeImpl
23:40:55Araq_not necessarily
23:41:48krux02yes I saw that the original verison required you to call getType(getType(x)) sometimes
23:42:07krux02but I don't think it feels natural that way
23:42:45krux02I like the distinction like in functions, whar you can call getImpl
23:43:34krux02I think there is semantic difference weather I call getType on an AST node, or I want the implementation of a type
23:43:43Araq_I think I prefer the getType2(whatToDoEnum) version
23:44:06krux02I looked into that, and realized that it doesn't work out
23:44:12Araq_why not?
23:44:54Araq_fyi c.gABC generates an ABC instruction.
23:44:59krux02for example when I want to get the implementation of a type that is contained in another type
23:45:15Araq_why?
23:45:31Araq_you need a way to traverse the type anyway
23:45:38Araq_you cannot special case too much
23:45:39krux02with the distinction in getType and getImpl I can call node.getType.sons[1].getImpl
23:45:50Araq_you need a general getChild operation
23:46:19krux02or in my case
23:46:30Araq_an ABC instruction is an instruction that takes up to 3 registers
23:46:38krux02node.getType2[1].getTypeImpl
23:46:50Araq_ABx would be register A with an immediate value in Bx
23:47:39Araq_the immediate value Bx is 2 bytes, every instruction is 4 bytes long. Except for "extended instructions" where multiple words are used. But these are rare.
23:48:27Araq_add regA, regB, regC would be an ABC instruction with opcode 'add'
23:48:42Araq_and the semantics are regA = regB + regC
23:49:25krux02with node.getType2(getImpl) I would need it to work an both nodes from the typed ast, and on type nodes returned from getType
23:49:47krux02with a distinct getImpl, that one only needs to work in results of getType
23:50:21Araq_what is the difference between a typed AST and type nodes returned from getType?
23:51:17krux02with typed ast, I just mean a general AST that I get in a typed macro
23:51:55*vendethiel quit (Ping timeout: 240 seconds)
23:52:33krux02even though both are represented in an AST form, they are something different to me
23:53:39Araq_but they are not ;-)
23:54:25Araq_if you ever access n directly and not n.typ in your getType2 implementation, it's pretty much always wrong, I think.
23:57:03krux02ok, then it might even work with the enum
23:58:49krux02even though I am not convinced that it is less confusing then the distinct method getTypeImpl
