The Whiteboard

Type must be a type provided by the runtime.

wtf .NET?

@Telastyn Code, or it didn't happen.

I can't paste the entire code for this one...

How about the line that's causing the error?

var ctorFn = typeLookup[ctor.EffectiveType].GetConstructor(invoke.Bindings.FunctionDefinition‌.Takes.Where(pp => !pp.IsIdentifier).Select(pp => typeLookup[pp.Parameter.Returns]).ToArray());

which.. totally seems like the sort of line to cause an error.

This translates it as "You can't reflect over a type that hasn't been created yet."

yeah

the message itself isn't very helpful though.

looks like I was trying to get the ctor of something like List<T>

1:30 AM

@Telastyn It does look like that. In the past, I've solved certain problems like this by using an Interface instead of a Class. Interfaces seem more amenable to being passed around and worked on as a T, because they don't have to be instantiated.

? that... doesn't make much sense to me.

Either way, I'm working on getting partial generic specialization working in my compiler. So I was literally trying to get the constructor for a generic type where T was not a concrete type - it was a generic placeholder to something else.

@ivan_pozdeev This question would be closed on Programmers as "too broad" for the same reasons it was here. It's basically asking us to design his entire app for him with almost no information. — Ixrec 31 secs ago

@MichaelT dare I ask what FAIL does?

Welcome on StackOverflow. Well good thoughs, but wrong site. Maybe this in on topic on Programmers, but not here since it is opinion based. — rekire 1 min ago

8:47 PM

@rekire Programmers.SE doesn't do opinion-based questions either, and we have a custom close reason specifically for language/tool/library recommendations like this one. — Ixrec 1 min ago

@rekire That's bad advice, since this question would be immediately closed on Programmers. Programmers.SE is about conceptual questions on software development, not for “soft questions”. Questions like this are explicitly off-topic. As an aside, opinion-based questions are off-topic anywhere in the Stack Exchange network, since these are questions and answer sites, not discussion forums. Good questions elicit objective answers, not opinions. — amon 28 secs ago

was I not harsh enough?

amon

I prefer to drop links to the help/on-topic in cases of blatant ignorance. Also, I had written up such a lovely rant before seing your comment that I didn't want it to go to waste.

That is correct -- during the transition from "failing" to "passing", your concern is having all the tests pass. Afterwards, you worry about the implementation. This question is too general to answer (it would probably be a better fit for programmers Stack Exchange), but basically, start with a the simple cases and work up to more complex ones. What happens when your input file doesn't exist? What happens if the file is empty? What happens if the file contains one letter? The first test might be "I can instantiate this class and get a valid instance"/ — Daniel Mann just now

@amit I feel like there is a lot of overlap between what's considered on-topic at Stack Overflow ("a software algorithm"), Computer Science ("algorithms, models of computation"), and Programmers ("algorithm and data structure concepts"), all quoted from their "on-topic" pages. In my opinion, if you can't tag a question with either a programming language (e.g. C), or environment (e.g. POSIX), then it's better suited for on of the other sites. This question could be answered and proven without writing a single line of code ("programming"). — Jonathon Reinhart 42 secs ago

@JonathonReinhart If I was asking this myself, I would pick Programmers, but I don't think there's any need to migrate this off SO. — Ixrec 48 secs ago

@MichaelT meh. Just because it fits doesn't mean it's a good idea. And even if it is a good idea, seeing code like that would raise my "clever" alarm. This instance of "clever" might be obvious and manageable, but what about the next 50?

Ixrec

@MetaFight is the purpose of FAIL obvious to everyone but me?

@Ixrec nah, I don't get it either.

I assume it's part of the rules of the game.... mixed into the encoding of the deck.

Nick Alexeev

You can lead a programmer to a white board, but you can't make him draw.
Majority of *pure* programmers are graphically challenged, I've noticed.

11:02 PM

what's a pure programmer?

durron597

@MetaFight a JIT virtual machine

all it does is reprogram your code to make it better and nothing else

Nick Alexeev

@MetaFight Pure programmer is a person who have done only coding throughout his career, and not much else. So, for example, a person who is writing code for the last 7 years, but was an optics engineer for the 7 years before that is not a pure programmer.

I could use the term purebred instead of pure.
