<trapped> is there any way to obtain the client's address from an HTTP::Request?
<BlaXpirit> trapped, you mean your own address?
<BlaXpirit> and local/global?
<jhass> Netfeed: just make an alias for now, alias SomeNumber = Int8|Int32|Int64|UInt8|UInt32|UInt64|Float32|Float64
<trapped> BlaXpirit: no, the client's address
<jhass> trapped: with or without reverse proxy in front?
<trapped> either
<trapped> considering nginx set X-Forwarded-For afaik
<trapped> thanks
<jhass> the socket's peer address doesn't seem to be exposed atm

<BlaXpirit> hmm... is the C-style formatting mini-language beneficial for Crystal
<BlaXpirit> i mean, %d and %s have exactly the same effect as far as i see
<BlaXpirit> >> "%3d" % "5"
<DeBot> BlaXpirit: # => " 5" - http://carc.in/#/r/bu2
<jhass> it probably should raise if passed a string, yeah
kyrylo has joined #crystal-lang
<BlaXpirit> are there some formatting options that can be combined with #{} interpolation?
<jhass> I'm not sure I get your question but I think the answer is no
<BlaXpirit> well, i can just wish it used Python's way
<jhass> (you might want to clarify you question)
<BlaXpirit> Python has this string formatting
<BlaXpirit> "{:3d} {named:3d}".format(x, named=y)
<BlaXpirit> which is equivalent to "%3s %3s" % (x, y)
<BlaXpirit> i find it quite good
<BlaXpirit> sorry, i meant "{:3} {named:3}".format(x, named=y)
<jhass> >> "%3d %{foo}" % 5, {"foo": "bar"}
<DeBot> jhass: Syntax error in eval:4: unexpected token: NEWLINE - http://carc.in/#/r/bu3
<jhass> meh
<jhass> >> "%3d %{foo}" % {5, {"foo": "bar"}}
<DeBot> jhass: # => " 5 bar" - http://carc.in/#/r/bu4
<jhass> we got these recently
<BlaXpirit> these "d" suffixes are kinda irrelevant
<jhass> don't think you can combine them with formatters yet I guess
<jhass> >> "%3d %{foo}10s" % {5, {"foo": "bar"}}
<DeBot> jhass: # => " 5 bar10s" - http://carc.in/#/r/bu5
<BlaXpirit> and what's nicest is each type can define its own formatting options
<jhass> >> "%3d %10{foo}s" % {5, {"foo": "bar"}}
<DeBot> jhass: ArgumentError: malformed format string - %'{' - more at http://carc.in/#/r/bu6
<jhass> >> "%3d %<foo>10s" % {5, {"foo": "bar"}}
<DeBot> jhass: # => " 5 bar" - http://carc.in/#/r/bu7
<jhass> >> "%5d" % "foo"
<DeBot> jhass: ArgumentError: invalid Int32: foo - more at http://carc.in/#/r/bu8
<jhass> there's your diff
<jhass> it does call .to_i on the arg for you
<BlaXpirit> ooh

<crystal-gh> [crystal] bjmllr opened pull request #1221: typeof: add type flattening example (gh-pages...doc-typeof) http://git.io/vsItM
<BlaXpirit> so I made a Deque class that has a subset of Array's API but, of course, with optimal access to both ends, not just the right one
<BlaXpirit> and to very quicky test it without writing a lot of boilerplate,
<BlaXpirit> i want to execute the same things on a Deque and Array and check for equality after every step
<BlaXpirit> so uh something like this works https://bpaste.net/show/67ad8bd36937
<BlaXpirit> but it's kinda ugly and i don't know how to do it without globals / inside `describe`
<BlaXpirit> the reason i'm doing this is there are very many things that can go wrong with the implementation details
<BlaXpirit> i even considered fuzzing, but instead i just wanna write a sequence of actions that trips up all the potential problematic tests
<BlaXpirit> problematic places*
<BlaXpirit> and in addition to that i'll just write normal simple tests of methods
<jhass> make a class?
<BlaXpirit> jhass, u mean this pattern is ok but i just wrap it in a class?
<jhass> pretty much, stdlib spec doesn't allow for much more

<ddfreyne_> Ah man, I love Crystal's stack-allocated structs. Been replacing some classes with structs and arrays with tuples, and performance went way up.
<BlaXpirit> :>
<ddfreyne_> + lldb and set a breakpoint at __crystal_malloc and you can eliminate all heap allocations.
