<dzv> STDOUT.sync = true
<jhass> maybe we should make it the default?
<dzv> the current behavior is similar similar to stdio i think. buffering is line by default if the output is a tty, otherwise full buffering
<dzv> if i remember correctly
<dzv> i have little to no opinion on the matter. buffering does increase performance some, especially with very small writes. you could probably change the default from line buffered to no buffer when stdout is a tty
<dzv> that MAY effect the performance of some curses programs that manage the output buffer manually
<jhass> mh, yeah that might be a good idea. I'd rather have curses programs turn it off manually than the common case turn it on manually
<dzv> no buffer may also effect the performance of data spewing programs that do lots of small writes. i think those are the most common in unix
<jhass> but in those cases you usually pipe the data somewhere, no?
<dzv> normally, except by accident or tee
<dzv> honestly i don't think it matters much as long as it's buffered when not a tty
<jhass> yeah
<dzv> jhass: thoughts on https://github.com/manastech/crystal/pull/1428 and how that starts to solve problems mentioned in https://github.com/manastech/crystal/issues/835 ?
<jhass> I'm afraid I'm really not into the plans for the IO design
Ven has joined #crystal-lang
<dzv> you mean splitting them in to different interfaces?
<dzv> or you don't care?
<BlaXpirit> in every case that i'm aware of, stdout is buffered
<BlaXpirit> as much trouble as it causes, seems like it's worth it
<jhass> dzv: I mean in general, I think asterite & waj have some general ideas for the stdlib IO design but I'm not in their heads ;)
<dzv> it's always newline buffered. the tty checks were for something else
<dzv> jhass: like what?
<dzv> how do i get in their heads?
<jhass> it's an idiom. It means I don't know what their plans are and can't predict them either

<vegai> hmm, does to_s really require a parameter for an io typo
<vegai> typo=>type :P
kgadek has joined #crystal-lang
<willl> vegai: yes and no. Object has a #to_s with no parameters that calls the #to_s(io : IO) that you define on your classes https://github.com/manastech/crystal/blob/master/src/object.cr#L79-L95
<vegai> ok
<vegai> does ruby does it like this too?
<willl> no, it just uses the first #to_s it finds as it goes up the method lookup chain
<vegai> it seems sorta magical how it works in crystal
<vegai> if I have an object f whose to_s is "io.puts("Foo")"
<vegai> and I call puts f
<vegai> meh, perhaps I'll just check the code if I care enough why it works
Ven has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]

<apt-get_> hey
<apt-get_> I wanted to know, is there an equivalent for the fileutils lib on crystal?
<apt-get_> I wanted to test a quick project with Fileutils::mkdir_p
<apt-get_> but it doesn't recognise the lib
<jhass> apt-get_: iirc we got mkdir_p on File
<jhass> or Dir
<jhass> http://crystal-lang.org/api/Dir.html#mkdir_p%28path%2Cmode%3D%3Cspanclass%3D%22n%22%3E511%3C%2Fspan%3E%29-class-method
<jhass> yup
<apt-get_> jhass: thanks
<apt-get_> also, how is `raise` supposed to be used?
<apt-get_> it just showed me a "wrong number of arguments" exception
havenwood has joined #crystal-lang
<jhass> apt-get_: pass it an exception instance, raise ArgumentError.new("meh")
<apt-get_> oh
<apt-get_> ok
<apt-get_> jhass: probably last time I'm gonna bother you
<apt-get_> what's with this error? Why should I give a pointer for the File#file? method
<jhass> your dir variable may be a Bool
<jhass> make sure it's a string only
<apt-get_> jhass: it's wrapped up in a "unless dir == false" condition
<jhass> #== is a method call so crystal can't infer anything from that
<jhass> make that if dir.is_a? String
<jhass> or set dir to a String or nil and just if dir
<apt-get_> jhass: yeah, seems like so
<thor77> does anyoe have some ideas for porting tail to crystal?
kgadek has quit [Ping timeout: 264 seconds]
<jhass> File.foreach and count lines?
<jhass> mmh, guess you'll have to read it into memory once
<apt-get_> jhass: foreach doesn't work I think
<apt-get_> Error in ./file-converter.cr:21: undefined method 'foreach' for File:Class
<jhass> or read twice, counting \n's and remembering offsets
<apt-get_> I had to replace it with File.read.each_line
<jhass> oh
<jhass> well, that's not better than File.read_lines
<jhass> ah, there we go http://crystal-lang.org/api/File.html#each_line%28filename%2C%26block%29-class-method
<jhass> File.each_line is a thing
Ven has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<apt-get_> also, what's the equivalent of `equal?` ?
<thor77> https://github.com/flori/file-tail/ maybe i can just take this implementation and convert it
<jhass> apt-get_: I can never remember what that one is, object identity?
<apt-get_> yeah jhass
<jhass> mmh, I guess you can compare the #object_id's for now
<apt-get_> in ./file-converter.cr:56: undefined method 'gsub' for (Int32 -> Void) (compile-time type is (String | (Int32 -> Void)))
<apt-get_> this happens even if I wrap the variable into a `x.is_a? String`
<apt-get_> uh
<apt-get_> I mean if I wrap the line
<jhass> ?code
<DeBot> jhass: Nothing known about code.
<jhass> ?code=We can't help you without your code, please post it to https://gist.github.com
<DeBot> jhass: Set code.
sadin has quit [Remote host closed the connection]
<jhass> team[:team] is a method call, the return value may change between invocations
<jhass> assign it to a local variable, then resolve the union on it
Ven has joined #crystal-lang
<apt-get_> okay
<jhass> alternatively try to use something that doesn't create so many unions. For example we got the record macro which is similar to Ruby's Struct.new
<jhass> >> record Foo, team, callback; foo = Foo.new("foo", -> { puts "hi"); foo.team.gsub("o", "e")
<DeBot> jhass: Syntax error in eval:4: unexpected token: ) - http://carc.in/#/r/enf
<jhass> >> record Foo, team, callback; foo = Foo.new("foo", -> { puts "hi" }); foo.team.gsub("o", "e")
<DeBot> jhass: # => "fee" - http://carc.in/#/r/eng
<jhass> asterite: got my pm btw?
<jhass> oh, signed off already -.-
<apt-get_> I'm wondering how to check if an index isn't out of bounds in an array
<apt-get_> before trying to check that index
<apt-get_> oh
<apt-get_> array.size
<thor77> whats the best way to count the lines of a file?
<thor77> just some loop with File.each_line?
Ven has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<thor77> but i think it's not that efficient for tailing (doing it every second)
<thor77> maybe i should monitor File.size and if it changed, count lines
<jhass> File.read(...).count("\n") I guess
<jhass> the most efficient way would be to read through it bytewise and compare, but should be good enough
<buggs> is count memchr?
<jhass> no, I don#t think memchr handles UTF-8? ;)
<buggs> then he might want to use a byte representation
<jhass> besides String#count's argument is interpreted the same way (well, close, might not handle all cases yet) as Ruby's
<apt-get_> is the --cross-compile option working?
<apt-get_> it just gives me undefined constant Stat
<jhass> depends on the target
Ven has joined #crystal-lang
<jhass> what do you want to cross compile to?

<rhaps0dy> does crystal have two namespaces, one for functoins and one for variables?
<rhaps0dy> else content = content() in a loop doesn't make much sense
<apt-get_> jhass: oh, sorry
<jhass> rhaps0dy: it's like ruby, locals take precedence over methods if there's ambiguity
<apt-get_> windows
<apt-get_> I'm honestly just testing things around
<apt-get_> I have mingw
<jhass> apt-get_: there's no windows support yet
<jhass> ?windows
<DeBot> Windows support is currently developed at https://github.com/xwanderer/crystal/tree/win32/win32
<apt-get_> okay
<thor77> rhaps0dy: i just don't want to parse the file twice, if there are new lines
<thor77> content = content looks confusing to me
<jhass> thor77: could rename the method to read
<thor77> yeah, good idea
<thor77> let's see if i get it to integrate it into the File-class, like to_json does for some other objects
<rhaps0dy> jhass: interesting
<rhaps0dy> so you can have a variable with the same name in kind of a stack of scopes?
<rhaps0dy> if you can define functions inside functions
<jhass> you can't define functions inside functions (nor functions inside methods or methods inside functions)
<travis-ci> manastech/crystal#691f89d (master - Merge pull request #1430 from will/benchmark-ips-interactive): The build passed. https://travis-ci.org/manastech/crystal/builds/79681083
tomchapin has joined #crystal-lang
<rhaps0dy> ah, then there's no stack. better
<jhass> well, there's a callstack, but scope wise there are only closures
<jhass> and method and function definitions do not closure, only blocks & procs do
<rhaps0dy> didn't expect that
<rhaps0dy> you have a different designation for a closure-function and a regular function?
<jhass> yes, the "closure function" is called Proc and is actually an instance of the class Proc and thus anonymous
<jhass> functions are not really used unless you do lowlevel external interfacing, in normal highlevel program you'll only have methods and Procs
<jhass> although toplevel methods are kind off like functions as they do not have a self
<jhass> but maybe I convince Ary to change that sometime :P
<rhaps0dy> I see. Nice way of duplicating implementation of objects and closures with having closures be an object too
<rhaps0dy> wha, toplevel methods?
<rhaps0dy> alright alright
<rhaps0dy> for consistency, self might be the "global scope" ?
<rhaps0dy> not sure you have that
<jhass> yeah we don't really, toplevel stuff is mostly file private
<jhass> in Ruby the toplevel scope is actually an anonymous instance of Object
waj has quit [Remote host closed the connection]
<rhaps0dy> I think that's better in the long run really, no truly global scope.
<jhass> so you're kind implicitly inside a class definition, in ruby
<rhaps0dy> which is different for every file?
<jhass> ah no, in Ruby it's actually shared, though locals are still file private iirc
<rhaps0dy> I see.
tomchapin has quit [Read error: No route to host]
tomchapi_ has joined #crystal-lang
<jhass> btw constant scope is truly global ;)
<jhass> but I have some prospect of getting $global_variables dropped
<rhaps0dy> is $global_variables where constants are stored?
<jhass> no
<jhass> just a type of variable we have
<jhass> local_or_method, @instance, @@class, $global, Constant
<rhaps0dy> so there are "globals", explicityl marked as such
<jhass> yeah, the name of the variable determines its scope

<Papierkorb> When interfacing with C, how do I declare a struct whose size I don't know?
<Papierkorb> I also don't know what's in it, nor is it ever to be new'd or collected in crystal
<Papierkorb> is type TheStruct = Void* good enough?
<jhass> Papierkorb: do you have to allocate it via crystal or is there some sort of struct foo* make_me_foo()
Ven has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<Papierkorb> jhass: the latter
<jhass> then just type or alias it to Void*, yeah
<Papierkorb> How can I print out the address of TheStruct (as in Void*)? Much like printf("%p", the_pointer);

<jhass> mmh
<jhass> can you call .address ?
<jhass> or .inspect ?
<Papierkorb> Ah. jhass, I built the binary and called it manually, it segfaults

<Papierkorb> I actually once wrote a C/C++ parser (based on Clang) which you can feed Lua scripts to generate code. Maybe one could use that to auto generate crystal bindings too
