but gosh the error checking really rubs me the wrong way
10:48

it seems that lot of the practical code just returns the error up in the call stack

until it's handled in fewer places

so not sure how it's exactly better than exceptions, but i'm biased

Given I have 32 bits, how do I convert that BitArray of 32 to a Int32?

15:54
<

jeromegn: there's no way, maybe we could provide access to the internal buffer
15:56
<
jeromegn >
well, I created a BitArray like:
15:56
<
jeromegn >
> require “bit_array”; ba = BitArray.new(32); ba.toggle(2); puts (pointerof(ba) as Int32*).value
15:56

hmm, can’t remember the bot syntax
15:57
<
jeromegn >
but I have no idea if that’s correct
15:57
<
jeromegn >
for some reason I was expecting 4!
15:58
<
jeromegn >
(I’m comparing with the MongoDB Ruby Driver to see how they send a BitArray through the socket for the MongoDB Wire Protocol)
15:58
<
smarr >
asterite: ok, thanks
15:58
<
jeromegn >
there’s a flag that’s sort of like an enum but must be sent as a Int32 representing a BitVector (BitArray).

one of the things I'm used in ruby is trying to get a hash or an array item and if it does not exist get nil

I know you can set a default value when creating hashes
21:33
<
BlaXpirit >
jfontan, ok
21:34
<
jfontan >
but reading json I don't see a way to do it
21:34
<
jfontan >
should I start checking the key explicitly?
21:34
<
jhass >
jfontan: append a ?, foo["bar"]?
21:34
<
BlaXpirit >
that took so long to parse
21:34
<
BlaXpirit >
basically foo["bar"]? is the code to do it
21:35
<
BlaXpirit >
instead of foo["bar"]
21:35
<
jhass >
like foo["bar"] calls the method named [], it calls the method called []?
21:35
<
jfontan >
so it's better to check
