that is a lie btw nobody is productive in c++

what the gently caress is even the point of c++

it feels like some sort of programmer dick measuring contest that got really out of hand

there are two important axioms of c++:
1. every language feature the committee can think of shall be included
2. the runtime cost of any language feature shall be as minimal as possible, preferably zero
the rest of the language follows

c++ is not poorly thought out, it is very well thought out in great detail by experts, but it sucks because of those goals

As an example: The reason we're getting co_yield and not yield as a keyword is because Solaris has a system call named "yield". Additionally, many agricultural businesses have code where "yield" is a variable name

Or they could add a reserved word _Yield (every symbol starting with an underscore followed by a capital letter or another underscore is reserved for the language impl) from the namespace they actually do own and then add a header called <coroutine> (header names with no period in them are reserved) that #defines it to yield, but I guess that would be the smart thing to do

Jabor: Jul 16, 2010; #1 Loser at SpaceChem

just make it a keyword that stops being a keyword if there is some other thing named "yield" in scope

you already need to know what names are in scope to parse the language correctly, so it's not a huge burden

if your language is already definitely parseable then it's a horrible idea yeah

but you already need to know what names are in scope and what they represent in order to figure out what

I'm trying to grep a string

"[info] 17.21.0-11-38poopbutt-SNAPSHOT"

i'm doing

code:

sbt project version | grep "\[info]\"

and there are no matches

doing

code:

sbt project version | grep "[info]" # or grep \[info\]

does character matches on i, n, f, and o

i want to match all of "[info]" including the brackets

wtf is going on?? i've had a bit to drink but this seems totally wrong

30 TO 50 FERAL HOG: Mar 2, 2005

so im bad at sql sserver

code:

DECLARE @return int

	SELECT  TOP 1
			@return = PIN + 1
	FROM    [dbo].[Product] OuterSearch
	WHERE   [OuterSearch].[Category_ID] = @ID
			AND
			NOT EXISTS
			(
			SELECT  NULL
			FROM    [dbo].[Product] InnerSearch 
			WHERE   [InnerSearch].[Category_ID] = @ID
					AND
					[InnerSearch].[PIN] = [OuterSearch].[PIN] + 1
			)
	ORDER BY
			PIN

	RETURN ISNULL(@return, 1)

basically im trying to find the first "gap" in the PIN column for a given Category ID, it works great except if the first available PIN is 1

so for example

[1, 2, 3, 5, 6, 7, 8]

will return 4, which is correct

[] (no results)

will return 1 thanks to the "ISNULL(@return, 1)", which is correct

and

[2, 3, 4, 5, 6, 7, 8]

will return 9, which is wrong. it should return a 1

could someone please tell me exactly in what way i am an idiot?

gonadic io: Feb 16, 2011; >>=

quick terrible programmer question: i'm working with a db that defines a (read-only) date as 3 ints (year, month, day). I cannot change this fact.

i would like to define inequalities on this type that don't require complex functions that gently caress with indexing/optimisers like 'concat', or 'date' to actual parse. i would like to just do inequalities on the ints.

I am assuming that all dates are valid i.e. month is never above 12, and none of the fields are 0 or below.

What I have, that works is (in scala):

code:

    case class Date(year: Int, month: Int, day: Int)
    
    def lt(a: Date, b: Date): Boolean = 
        a.year < b.year || 
            (a.year == b.year &&
                (a.month < b.month ||
                    (a.month == b.month && a.day < b.day) ))

But I can't figure out a way to simplify this, is there a way or am I going to have to copy/paste this into every query?

i don't mind it, the shell is fine and the language has warts but it's still way nicer than bash scripting. what don't you like about it?

not looking at your code but from your test cases your sql returns the smallest pin+1 where pin is in your set and pin+1 isnt so you should probably add a 0

can you not do (a.year, a.month, a.day) < (b.year, b.month, b.day)? that should work in MySQL

alternatively you could compare a.year*366+a.month*31+a.day

nope, that's correct. use your language's datetime instead of creating your own. alternatively, convert to a datetime in your proc before returning.
