QUESTION
The macro below works if tuple defined in-place but not if it's defined via type-name.
...ANSWER

QUESTION
I want to define a type using struct in typed/racket. For example :
...ANSWER
Answered 2021-Mar-24 at 12:08The idiomatic way is to use an Option
type, which you can find in the docs here.
Note that this essentially amounts to using #f
as your "null" version of the value. Racket also has the nice property that any value other than #f
is truthy, so we can check for "null-ness" by doing:
QUESTION
I have the following struct defined with the typedef keyword:
...ANSWER
Answered 2021-Mar-11 at 16:56NODE
is not the name of the struct. It's a typedef
, i.e. an alias for the struct. In the first case, the struct is unnamed. In the second case, the struct is named struct n
.
The reason you can't use NODE
inside of the struct is because that name hasn't been defined yet at the time it is used. So you need to use the actual name of the struct (which is defined) in order to create a pointer to it.
Also note that the struct
keyword is required in C when using the struct's name, i.e.:
QUESTION
Unscoped enumeration WORKS with the OR operator where the scoped one does not... WHY and how to work with it?
The enum type type-name is unscoped. Prefer 'enum class' over 'enum' (Enum.3)
...ANSWER
Answered 2021-Feb-19 at 18:36enum eDogType
values are processed as int
values, where enum class eDogType
values are not (they are processed as values of type eDogType
).
So in the first case, the operator | (int, int)
is used, whereas in the second case, the operator | (eDogType, eDogType)
is needed (but not found).
QUESTION
When using the sizeof
I always enclose it in parentheses, as it's a bit easier for me to read, even if I can sometimes omit it, in the first case below
ANSWER
Answered 2021-Feb-10 at 19:23Accepting a typename after sizeof
would not allow all types to be specified in an expression: pointer types (eg: sizeof char * 10
) would create an ambiguity complicating the parse, which currently is quite simple.

QUESTION
I'm writing a utility function to look for elements in containers like so:
...ANSWER
Answered 2021-Jan-25 at 18:18template
typename std::enable_if::value, void>::type
struct In {
QUESTION
I realize this is a pretty basic question, but I just want to confirm that I'm using std::enable_if
correctly because I'm a little uncertain what the "correct" error messages should be when attempting to call a disabled function.
Consider the following program (link), which is expected to not compile:
...ANSWER
Answered 2020-Dec-30 at 17:12std::enable_if_t
is a template that causes substitution to fail if the condition is false. Because of SFINAE this does not cause the program to be ill-formed, when it happens during overload resolution. You are passing it a false value as the default value, so for a call to function()
, without any additionally specified template parameters, overload resolution will fail.
If you change template
part to int Z = 1
then I would expect the code to compile.
More to the second part of the question: Are these other errors expected?
QUESTION
Is it possible to use the type-name (class) as a keyword in the constructor? As similar as possible in the route?
...ANSWER
Answered 2020-Nov-11 at 11:39Unfortunately, no - C# does not have a keyword or other way to avoid having to repeat a type-name (e.g. your class's name) in code. Indeed this is a pain and an annoyance, but there's no way around it (unless you count code-gen or Roslyn extensions, but let's not go there).
BTW, in this particular case (ILogger
), the T
parameter is only used by DI to set the Source
/ SourceContext
internal parameter of the Logger (depending on what Microsoft.Extensions.Logging
sink you're using) and it isn't required for instances, so you don't need to specify it in your field's type.
So you can do this:
QUESTION
Im trying to parse into a struct containing a std::string and std::vector, but I always get a error when using the %-operator of Boost Spirit.
I already tried to isolate the list parsing into a seperate rule (source) and the as<>
-directive from this question
Without the predicate_arguments
rule it works perfectly.
The error is pretty big, some snippets:
...ANSWER
Answered 2020-Jul-02 at 11:57I forgot to import the ast_adapted.h
into my decfile_parser.h
. The error was because the struct of course was not adapted to a Fusion Sequence.
