<BlaXpirit> Hello. What are my options if I would like to distribute binaries compiled with Crystal? Looking mainly for Linux currently.
<BlaXpirit> My main concerns are dynamically linked libraries, all kinds of unexpected dependencies that won't let someone run it on another computer

<waghanza> hi all
<waghanza> new in crystal community
umurgdk has quit [Ping timeout: 260 seconds]
<waghanza> I wonder know how to solve type inference
<waghanza> I have `Error type must be (Nil | String | Float64 | Bool | Int64 | Array(JSON::Type) | Hash(String, JSON::Type)), not (Nil | String | Float32 | Float64 | Bool | Int32 | Int64 | Int8 | Int16 | UInt8 | UInt16 | UInt32 | UInt64 | Array(JSON::Type) | Hash(String, JSON::Type) | Array(MessagePack::Type) | Hash(MessagePack::Type, MessagePack::Type))`
<waghanza> where could I check if type check is forced ?

<asterite> BlaXpirit: that's a good question. I don't have an answer, but we should maybe think of a way to do it. Maybe if the programmer provides static libraries, somehow (option to the compiler) then it can link them statically

<ton31337> it's from an example: http://crystal-lang.org/api/UDPSocket.html
<asterite> Oh, seems the example is outdated, that method doesn't exist anymore
<ton31337> what should I use?
<asterite> Do you need to read an exact number of bytes?
<ton31337> actually I want to read the whole message
<ton31337> no need to limit characters
<asterite> You can use `.gets_to_end`

<plukevdh> having some trouble with recursive alias types
<plukevdh> Couldn't find overloads for these types:
<plukevdh> - Hash(String, HashFormatter::Type)#[]=(key : String, value : Array(String | Float64 | Bool | Int64 | Hash(String, HashFormatter::Type)))
<plukevdh> where HashFormatter::Type is defined as
<plukevdh> alias TerminalTypes = String | Bool | Int64 | Float64
<plukevdh> alias Type = TerminalTypes | Array(Type) | Hash(String, Type)
<plukevdh> i figure the case being complained about is captured by Type
trapped has quit [Ping timeout: 252 seconds]
<plukevdh> its very similar to what JSON::Type is doing
<plukevdh> asterite ^^
<asterite> plukevdh: add `as Type` after `hash_key(k)` and `hash_key(v).not_nil!`

<adam|> Any way to override output of `inspect` at instance level?
<jhass> Since you can't redefine methods of instances in Crystal, no
<jhass> why?
<adam|> Just looking at prettying up some output when inspecting.
<jhass> well, you can redefine inspect on the class and try to detect the correct instances or whatever
