do blocks establish scope?

I guess?
<bnagy>
blocks have a block local scope
<bnagy>
but they can see all the locals in the scope in which they're defined
<bnagy>
which is a thing known as a closure, they 'close' over all the locals in their binding
<fwchld>
ok so if we had block { variable1 block2{ foo }} can block2 see variable 1

yes

When you verify a signed bit of data, it returns that bit of data - don't think that would work if signing did a hash

The OpenSSL::RSA module doesn't have the option of signing, just encrypting

it might assume that you implement sign by hashing and then encrypting the plain text

hi popl
<babilen>
certainty: So, "foo-bar-baz" is not a valid symbol (by nature of being a string) and foo-bar-baz is also not a valid symbol (due to it contianing -) ?
pwh has joined #ruby
<tobiasvl>
yep
<popl>
Hi apeiros.
<certainty>
babilen: correct
<certainty>
babilen: you can make it a symbol though.

Are you in a hurry to get those tests? I am just wondering. I do not plan to flake on it but I work from 16:00 to 01:00 and am usually pretty tired when I get home.
<apeiros>
:"foo-bar-baz" is a symbol
<apeiros>
foo-bar-baz is the expression foo.-(bar.-(baz))
predator117 has joined #ruby
<babilen>
certainty: Okay, and the program that uses this datastructure is likely to specifically expect symbols there and is not working with strings?

babilen: yeah I would assume it.
tkuchiki_ has quit [Read error: Connection reset by peer]
<tobiasvl>
so just use {:foo-bar-baz => something } instead
<babilen>
certainty: So there is no way to, well, somehow escape the string "foo-bar-baz" to turn it into a proper symbol?
<certainty>
{ :"foo-bar" => something }
<tobiasvl>
uh
<tobiasvl>
yeah that
<tobiasvl>
mine obviously doesn't work either
<babilen>

no, sorry. :"foo-bar-baz"
griffindy has joined #ruby

:foo-bar is not valid because it'd be (:foo).-(bar)

<apeiros>

<workmad3>
babilen: Vagrantfile is plain ruby because ruby is quite a nice configuration language in many situations
<babilen>
apeiros: I used '{ :"foo-bar-baz": salt.minion_pub }' which I know learned is wrong as this seems to require me to use => in lieu of : to separate "keys" from "values" (no idea what its called in Ruby)

babilen: it's called keys and values ;)

ianfleeton has quit [Remote host closed the connection]

with :"foo" symbols, you must use =>, not :
<apeiros>

<certainty>
babilen: we have special literal syntax for the case where the keys in a hash are symbols
<babilen>
apeiros: I can assure you that I wasn't aware of that. How come both "=>" and ":" are used? Is that simply a historic artifact?
<apeiros>
foo: can only be used with symbols that don't need quoting.
<popl>
literally
pigzzcanfly has joined #ruby
<apeiros>
babilen: {foo: bar} is newer
<apeiros>
reason for it is that it's shorter than :foo => bar, which is a very often used construct in method calls.
<certainty>
my theory is that it's this way to have a backwards compatible way to introduce proper keyword arguments
<certainty>
dunno if that's true
<apeiros>
yes
<workmad3>
babilen: key: value is a newer syntax (1.9) which, iirc, is basically there as a stepping stone towards keyword args (introduced in 2.0)
<apeiros>
that was the idea. IMO it backfired.

I really tried to figure this out by myself, but the sheer fact that http://www.ruby-doc.org/core-2.1.1/Hash.html uses "=>" while I encountered ":" lead me to believe that I am dealing with a different datastructure.

you'd have to duplicate checks, which is worse than a simple nested if

Using exceptions for flow control is awful, but a reasonable and known design pattern. But your exceptions have to be exactly correct for that. (obviously) Stuffing stings into them is like trying to use them as GOTO
