<workmad3> snkcld: it's still a method call, but yeah, afaik they just return 'self'
kitak has joined #ruby
mercwithamouth has joined #ruby
<snkcld> what i mean to say is, do the to_ whatever functions continue to attempt to process the conversion, even if the type of the object is already the type to be converted to
<Morrolan> Yes. The various classes just implement it by returning self.
<Morrolan> E.g. Integer's definition of #to_i will be 'def to_i; self; end'
krisbulman is now known as [krisbulman]
<Morrolan> There's not really any other way to do it, as those functions *return* an object of the desired type, they can't just do nothing.
benzrf has joined #ruby
<benzrf> so a rack middleware is basically a proxy to your app?
<Hanmac> same goes for the Kernel Functions like String() because they only call to_s and the others
<snkcld> ah, awesome!
<benzrf> nestable proxies?
<snkcld> thanks
<Morrolan> :)
<snkcld> well the actually conversion logic is in c, i would think
<snkcld> ?
<snkcld> atleast for mri ruby
<Morrolan> Probably is, yea.
bradhe has quit [Ping timeout: 252 seconds]
<Morrolan> You could check on ruby-doc.org, it includes the source for each method. :)
<Morrolan> http://ruby-doc.org/core-2.1.0/Integer.html#method-i-to_i - yea, it's C, at least for this class.

<workmad3> benzrf: a rack middleware is something that implements the rack interface but passes on to another rack application
<workmad3> benzrf: to allow you to create a stack
<workmad3> benzrf: so yeah, it's a type of proxy, but that's probably a less useful way to think of it ;)
<benzrf> ok
<benzrf> i guess 'delegate' might be a better word

<chipotle> can someone tell me what's wrong with this code? i'm new to ruby, but it says after completing the input that i have 574 characters in my name, which is not true: http://pastie.org/8670424
<Morrolan> You're adding strings, which will concatenate them.
<Morrolan> Sum them before you call #to_s
shedd has joined #ruby
<Morrolan> >> "5" + "7" + "4"

<Morrolan> Unlike Perl, Ruby won't implicitly convert between types depending on the operation.

<Morrolan> chipotle: Something like "Did you know that your name has " + (first_name.length + middle_name.length + last_name.length).to_s "characters?"
<chipotle> oh i see
<workmad3> I'd probably use string interpolation for that
<Morrolan> Basically, sum them while they are still numbers, then convert the sum to a string.
<Morrolan> Yea, me too. But one step at a time. ;D
<workmad3> :)
<chipotle> i get this: chapter6.rb:18:in `+': no implicit conversion of Fixnum into String (TypeError)
<chipotle> from chapter6.rb:18:in `<main>'
<Morrolan> Now you're probably missing the to_s on the sum.
<Hanmac> workmad3: or String#%
<chipotle> where's the sum, i don't see how to add it?
<Morrolan> Right now you are asking Ruby to do `"Did you know that ..." + 547`, which it has no clue how to do.
<Morrolan> What is your current code?
<f4a244c> decided to go ahead and implement a standards recommendation (informal): https://gist.github.com/jkassemi/8641384 - what's the closest to an informal collection of RFCs we have for stuff as basic as this?

<Morrolan> Oh, you still have the .to_s after first_name.length and middle_name.length
<Morrolan> You'll want to sum the numbers, not two strings and a number.

ghanima has quit [Ping timeout: 252 seconds]
<workmad3> chipotle: 'first_name.length.to_s' turns that number into a string
<pontiki> add the lengths, not the lenghts as strings
<pontiki> sorry, workmad3
<chipotle> so remove the to_s?
<pontiki> ^
<workmad3> pontiki: np, yours was slightly better stated than mine ;)
<chipotle> when i remove the to_s i get this error message: chapter6.rb:18:in `+': no implicit conversion of Fixnum into String (TypeError)
<chipotle> i guess i don't know what you mean by adding the lengths?
<Morrolan> Then you probably removed the wrong .to_s.
<chipotle> does that mean just turn it into a number and not a string?
<Morrolan> Eh, let's start at a more basic level.
<pontiki> after you calc the total length, then that needs tobe stringified
<Morrolan> Oh, pontiki will help, I'm out then. *grins*

<benzrf> returning means saying what the result of the method is
<beginnerrubyist> To display to the screen right?
<beginnerrubyist> Oh ok.
<benzrf> beginnerrubyist: for example, if I say '3 + 4', I don't expect that to print '7'
<benzrf> i expect it to result in 7
<benzrf> similarly in that example, 'foo' should come out to 3, not print 3
<benzrf> same as if I just wrote 3 instead of foo

<chipotle> beginnerrubyist: i have the ebook, yeah
<chipotle> would you like it?
<benzrf> chipotle: that;s because lpthw is different probably
<centrx> beginnerrubyist, the terminal is external to the program. When the program wants to print to the terminal, it sends the data to "stdout"
<beginnerrubyist> Aw, I want a book too.
<benzrf> chipotle: it emphasizes learning to do tasks instead of comprehending the big idea
<centrx> beginnerrubyist, That is what puts does
<benzrf> chipotle: which imo is dumb
<beginnerrubyist> centrx, oh ok. Thanks.
<benzrf> chipotle: from what ive seen of it anyway
<beginnerrubyist> What is stdout
<benzrf> beginnerrubyist: it's like a special file available to programs
<chipotle> once i finish this book, i'll go onto the well grounded rubyist

<centrx> beginnerrubyist, Unix-like systems have three standard "streams", stdout, standard output, stdin, standard input, and stderr, standard error. By default these read and write to the terminal
<SmoothPorcupine> I recommend learning C and seeing what ASM is.

<SmoothPorcupine> Ruby is very systems level as it is.
<emanu> I don't understand your logic
<SmoothPorcupine> Trying to weasel some random gem into the design process is a bad idea.
<beginnerrubyist> I think I understand now, instance variables are only in classes.
<benzrf> emanu: a shell script by definition is a script in a shell language
<emanu> the goal is to distribute this to people so that they get interested in using it
<benzrf> beginnerrubyist: erm
<benzrf> beginnerrubyist: no, they are variables that are scoped to an object
<emanu> so I'm chosing ruby in the hopes that my install process is like this: "gem install backup-tool"
<emanu> and no more
<benzrf> ...which may be what you meant
<beginnerrubyist> instance variables are accustomed the way they're because each instance of a class may have different instance variable values right?
<benzrf> you mean named?
<beginnerrubyist> benzrf, oh

danshultz has quit [Ping timeout: 272 seconds]
<benzrf> beginnerrubyist: lvars are scoped to each time a method runs
<SmoothPorcupine> emanu: In basic terms, all you're doing is copying files, right?

<cong> beginnerrubyist, you're just confusing yourself so do this https://eval.in/95233
<emanu> smooth: but I need a maintainable repository of osx applications and the files that are safe to symlink for them. These file lists will also likely change with every version of the application, so I need to build in version detection
<emanu> sorry, that was for SmoothPorcupine
<emanu> so it doesn't seem as simple as just copying files
<benzrf> cong: i do not think solving it for them is very helpful
<benzrf> （´＿｀）
<emanu> so I feel the toolset of ruby has some good solutions to this problem
<beginnerrubyist> cong ty, this is the help I need.
<cong> we need to be more helpful.
<SmoothPorcupine> emanu: Regardless of which files get copied, that's basically the final end result operation being performed, yes?
<emanu> SmoothPorcupine: no, it's actually version detection of the application it's backing up first (the harder problem), and then moving the "safe" config files for the version that was detected
<SmoothPorcupine> Right, but that's deciding which files to move.
<SmoothPorcupine> In the end, you still need to move them to have done anything useful.
<emanu> yea, the core problem to solve
<emanu> and then yes, I will move and symlink files
<emanu> but I don't think sh/bash is a good tool for solving the hard problem, no?

<fantasticsid> i want to use define_method to dynamically define a method

Lewix has joined #ruby
<centrx> fantasticsid, define_method takes a block, and the parameters of that block are the parameters of the method
soba has joined #ruby
ev1luti0n has joined #ruby
<centrx> define_method(:my_method) { |arg1, arg2| puts arg1 }
<fantasticsid> right
<ev1luti0n> im very very new ^_^ im trying to deploy an irc bot
<ev1luti0n> seems simple enough
<ev1luti0n> but it's my first time
<fantasticsid> so what if i want to programmatically pass in the name of arg1?
<centrx> I see
<centrx> Interesting
Aryasam has joined #ruby
<centrx> fantasticsid, Well, let's think about this, what is the reason for doing that, can't it be named anything?
<centrx> ev1luti0n, Go on...
<fantasticsid> reason i'm doing this is i want to generate some apis from a specifications programmatically, and for each method i have some required arguments, i want to pass in those required arguments..
<ev1luti0n> do i have to clone this install somewhere specific
yarou has quit [Remote host closed the connection]
<fantasticsid> i will be using the name of the formal arguments in the method definition body..
<fantasticsid> for eg.
<fantasticsid> if i have method_name = :square, arg_name = :x
<ev1luti0n> i was using git bash and it placed it in c:\user\username\bitches
<centrx> fantasticsid, Why does _your_ method have to have the same internal argument name as the API?
<ev1luti0n> is that fine
<centrx> fantasticsid, Is the dynamic method going to be used in an API with keyword arguments?
<fantasticsid> i want to programmatically generate def square(x) puts x.to_s; puts x * x end
<Steve445> anyone use RubyJS or Opal?
octoberry has joined #ruby
<fantasticsid> no, positional
zxq9 has joined #ruby
<fantasticsid> reason is those arguments are required arguments, so i want to generate positional arguments so the API is safer
gnephiak has joined #ruby
<centrx> ev1luti0n, That should be fine
e^0 has joined #ruby
<centrx> fantasticsid, But they can be named anything? If they are positional, no one sees the variable name except the compiler?

niklasb has quit [Ping timeout: 264 seconds]

xcv has quit [Remote host closed the connection]
<fantasticsid> but i still need to refer to those names in my method definition
<fantasticsid> actually the api will have multiple arguments
<fantasticsid> for eg., args_list = [:x, :y]
<centrx> I don't really understand, but you can use class_eval
<fantasticsid> ooh
<ev1luti0n> unable to convert "\x90" from ASCII-8BIT to UTF-8 for lib/1.8/bcrypt_ext.so, ski
<ev1luti0n> pping
<fantasticsid> i'm really new to ruby
<ev1luti0n> that's what happens when i install dependancies
<centrx> ev1luti0n, I think that is just a warning, not a show-stopping error?

<fantasticsid> so the question really is, once i have the method lists and required arguments names for each of these methods, how can i programmatically generate all apis like i'm doing here with create_domain..
<centrx> Okay hold on
<ev1luti0n> hey centrx this uses sqlite
<ev1luti0n> DATABASE_URL="c:\ruby200\bitches-master\bitches.sql"
<ev1luti0n> <--

icantbecool has joined #ruby
<ev1luti0n> it's defauled at sqlite:memory
icantbecool has left #ruby [#ruby]
daxroc has joined #ruby
<fantasticsid> maybe i'll just digress and simply collect all positional arguments and keyword arguments, zip them up with the required arguments list into a hash, then merge keyword arguments, and finally pass them to `call`
<fantasticsid> that way seems to be viable

ozgun has joined #ruby
<apeiros> bcz: that command contains already various variables, and you can't figure out how to insert another one? o0
<mikecmpbll> lol :D
<bcz> i want to know how to append variables
<bcz> means #{RECORD_FILENAME+i}?
DouweM has joined #ruby
<apeiros> well, appending is an operation on objects, not variables. assuming RECORD_FILENAME is a String, String#<< would be the append method
shime has joined #ruby
<bcz> and even then its not what i want because i would like to have "wave1.wav" and not "wave.wav1"
<apeiros> you can't do "string"+1, no.
<bcz> okay thanks. ill check that method
frankbutt has joined #ruby
<apeiros> well, separate suffix and filename then
<apeiros> I don't think you want to append, though.
<bcz> good idea. i just need to "combine" all those strings then
frankbutt has left #ruby [#ruby]
<apeiros> otherwise you'll have wave1, wave12, wave123 etc.
<mikecmpbll> i think you're looking for this utility method: `insert_counter_variable_before_file_ext(file, counter)`

<tobiasvl> why are you first checking if key INCLUDES "a", then if it's eql? to "b" or "c"?

<tobiasvl> what is key?
<DouweM> shay-: don't use eql?, just use ==
Advocation has joined #ruby
<shay-> DouweM: thought this is equal?
<shay-> thx
<apeiros> shay-: because precedence
<tobiasvl> shay-: are the keys symbols? if so, don't check against strings

<tobiasvl> shay-: did you see what apeiros wrote?

<shay-> tobiasvl: yes thanks this helps
<shay-> apreiros: but why is it doing so? :/

<Hanmac> solars: where does the IDs come from? from a lib, from you or are they user generated?
<apeiros> e.g. something like alpha = ['_', *'A'..'Z']; id.reverse.each_char.inject(0) { |numeric, char| (numeric + alpha[char])*27 }/27

<shevy> wiku5_ if you only care about basic input, Readline module + Highline gem should bring you far away. you can even make a disco prompt and use tab completion with that! and with Highling, you could disguise password input too through '*' characters. isn't that awesome? :D

<centrx> freeone3000, I would recommend installing a developer-friendly operating system. Mac OS X, Linux, and more are excellent operating systems.
<shevy> sickweezle sounds quite complex!
<centrx> freeone3000, But I assume there is a Ruby installer for Windows somewhere
<sickweezle> shevy: *sigh* Yeah. :(
<shevy> freeone3000 in this case, ruby-installer should allow quick updates
<shevy> I mean, ruby-install
<shevy> stupid name btw :P
<shevy> rubyinstaller is that win-only thingy isn't it?
<sickweezle> shevy: Here I was thinking I was following pretty decent practices for environment control. I may need to significantly rethink that ...
<shevy> sickweezle dunno. sounds pretty insane to me. but I dont use bundler nor rbenv (I guess you meant rbenv? you wrote rvenv). the daemons gem should be trivial though or? gem install daemons

<RubyPanther> He also said if you want to do everything with OOP then Ruby is a better language than Perl. That was the first time I heard of Ruby, in the late 90s. Then he gave a defense of procedural programming.
<RubyPanther> He in no way defended Perl's OOP as being good, just that it made that style of programming available

<Oog> is there a more robust timeout...?
<RubyPanther> Oog: At the extreme end is forking off a process and doing the timeout in the parent
<snkcld> heh. bnagy thanks, compact is perfect
<MrZYX> snkcld: I think that a .map {|i| i if condition }.compact is less flexible and less readable than a .select {|i| condition }.map {|i| i }. nil may be a valid element in the mapped array and for me it just reads backwards otherwise
