#pragma mark in Swift?
(20 answers)
Closed 8 years ago.
I want to organize my code by sections. usually I used #pragma mark - Section Name
but when I try to do so in a .swift file it doesn't work.
So my question is if I can somehow enable it and if not what is the way to organize my code in sections in a .swift file?
Use something like that:
// MARK: - UITableViewDataSource
Or use extensions: I love the way how UITableViewDataSource delegate is implemented in this answer

I have some struct Animal. I want to implement some methods on Vec<Animal>. I believe the correct way to do this is to create a new wrapper object called Animals. What is the correct object to make this wrapper, though? A struct? An enum? Something else?

Little bit confused with this code.
var _ QueryAppender = (*selectQuery)(nil)
I found this code in pg-go
repository and don't know why QueryAppender declared that way. Please explain me what is the use cases when I should declare variables that way.
This doesn't do anything at runtime, but unless the *selectQuery type satisfies the interface QueryAppender, compilation will fail. It's a kind of static assertion.

Difference between http.Handle and http.HandleFunc?
(4 answers)
Closed 5 years ago.
I'm trying to understand the differences between Handle and HandleFunc.
Other than the differences, when would you use one over the other when building a Go web app?
https://golang.org/pkg/net/http/#Handle
You'd use whichever one fits your handler implementation. If you've implemented your handler as a function, you'd use HandleFunc; if you've implemented it as a type with a ServeHTTP method, you'd use Handle.

I am working on some code that has paths that look like this:
"pack://application:,,,/FOO.Bar.Baz;component/Gorp/bazzle.xaml"
What do the 3 commas mean, and what is this path referencing?
Typically they are placeholders for parameters that were not supplied. It usually means ... "use the default values" for those parameters.
