Swift tip for #adventofcode day 13

Paste the input into your source code, add a comma at the end of each non-empty line, conform your Message type to ExpressibleByIntegerLiteral and ExpressibleByArrayLiteral, and let the compiler do the parsing.

[Rob Mayoff @rmayoff]

enum Message: ExpressibleByIntegerLiteral, ExpressibleByArrayLiteral {
case value(Int)
indirect case list([Message])

init(integerLiteral: Int) {
self = .value(integerLiteral)
}

init(arrayLiteral: Self...) {
self = .list(arrayLiteral)
}
}

#adventofcode 2022 day 6 in Swift:

print(
input.indices
.map { input[..<$0] }
.first { Set($0.suffix(4)).count == 4 }!
.count,

input.indices
.map { input[..<$0] }
.first { Set($0.suffix(14)).count == 14 }!
.count
)

Swift tip: don't take the intersection of a Set and a String

you may get the wrong answer

@krzyzanowskim @chriseidhof content and other are children, the parent created by the overlay modifier is ModifiedContent<C, _OverlayModifier<O>> (where C is the type of content and O is the type of other)

@danluu Was it not Carl Sagan who said “If you wish to pass sqllogictest from scratch, you must first invent the universe”?

[Rob Mayoff @rmayoff]

@krzyzanowskim probably you meant crave but idk for sure

[Rob Mayoff @rmayoff]

@hillelogram Other examples of this principle:

- LucasArts point&click adventures for 8 and 16-bit micros were built on in Unix on a VAX, including using a custom language (SCUMM) implemented with lex & yacc
- SNES Donkey Kong Country's sprites were 3D-prerendered on SGI workstations

who called it retrocomputing and not restoration hardware

@jckarter a computer programmer used to be disparagingly called a ‘punchcard’ but the modern insult is ‘presskey’
