I seem to be having some trouble calling methods in irb, I've created a class called Quarterback, initalized a new instance called "Andrew Luck" and have defined a method named "Audible" that prints out "WIDE EIGHTY", but when I try to call this method I get "undefined method `audible' for Quarterback:class". Any ideas what I'm slipping up on?

so, why does string interpolation allow for (almost) any kind of delimitter but regexes require / ? Just curious

they don't

I found and awesome weird dude that apparently does same languages. And the stuff is same like with C. So the focus now is how to digest a file/string efficiently.

Likely, reading it now already. elomatreb Would like to extend Digest with another algo, so need to be able to consume strings and files. And need that efficiently.
<A124>
How would / should I process the files? Send string with filename or other way? Searching gave zero resutlts so far.

dsea: just don't want to perturb the rails-h8rs in #ruby :D

like: FOO = 'Hello World!'

I don't mean frozen encoding

I mean: # frozen_string_literal: true

is this functionally equivalent to doing:

hi rubyists

I've just realized something I hadn't expected: ruby is difficult
<zacts>
but it's really a nice kind of difficulty
firstdayonthejob has joined #ruby
<elomatreb>
Are you sure you don't mean *programming* is difficult?
<zacts>
elomatreb: I think I must
<zacts>
:-P
blackmesa has joined #ruby
<zacts>
I'm being 1/2 silly though
<shevy>
zacts yeah, well, I would not say difficult because ruby is in many ways very linear the moment you "think ruby", but I would say that it is a complex language if you look at all it has to offer
<zacts>
shevy: indeed, I think that's what I meant also
leea has joined #ruby
<elomatreb>
Is there any language that is not complex?
<zacts>
Ruby offers a lot, and a lot of gems / libraries
ghr has joined #ruby
<zacts>
elomatreb: probably the closest would be pure lambda calculus or (scheme)?
<zacts>
but then you get complexity in the simplicity of it sometimes
<zacts>
some things become too terse to describe
<zacts>
I mean
<elomatreb>
(No expert, so take what I say with grains of salt) The complexity in these systems is having to do everything yourself

verbose not terse

s/terse/verbose/ for my first sentence mentioning it
<zacts>
indeed. so perhaps there is complexity in any system
<zacts>
but Perl5 makes me afraid, very afraid, in comparison to Ruby... oh well. :-P

elomatreb probably just different layers of complexity
<shevy>
like php versus haskell!
<shevy>
I went, for the most part, from perl to php to ruby
marr has joined #ruby
<elomatreb>
PHP to Ruby seems to be really common, I wonder why :)
<shevy>
I'd probably say that back in ... 2001 or so, php was the simplest of these three
<shevy>
I found PHP to be very lacking as a whole
<zacts>
one thing I love is the Ruby community
<zacts>
it's very welcoming, and also Ruby is well documented
<zacts>
and not just syntax, but design and semantics too
<elomatreb>
PHP, like javascript, is just not fun if you're used to the comfort of a well-designed standard library
<shevy>
I remember that my first project in ruby was an IRC bot. It was my last project in PHP and I failed. In ruby, a few weeks and it was working, with a bit of help from others in how to get select() to work in ruby (it was both a bot and a client at the same time)
<zacts>
I mean how to program ruby
ghr has joined #ruby
<shevy>
dunno I still think the documentation in ruby is not very good
<shevy>
but ruby as language is much prettier than both php and perl
<elomatreb>
To be fair, Ruby has undergone a lot less change than PHP. Old PHP versions look nothing like what we write today
kevr has quit [Ping timeout: 272 seconds]
<zacts>
Yeah, I'm referring to tutorial books, not to the Rubyspecs
<zacts>
on how to program Ruby
<zacts>
perldoc is probably nicer than the doc for the core language
<zacts>
or at least more comprehensive?
burgestrand has joined #ruby
<elomatreb>
Both Perl and Ruby have to be very well documented, simply because the "there is more than one way to do it"-pattern would cause chaos otherwise
<shevy>
that's a fair point, more complexity requires more explanation
<shevy>
have you seen those haskell monad tutorials

Java would be a good example. You can usually work with third-party code without opening a documentation website, because the language limitations combined with a few doc comments explain everything

hmm how do I match a whitespace character ?
ghr has quit [Ping timeout: 240 seconds]
<pontiki>
hk238: in a regexp?
karapetyan has quit [Remote host closed the connection]
<hk238>
or more specifically I'm editing a sublime syntax definitions file, and I'm trying to match a whitespace, problem is if I do `\ ` backslash and whitespace, then the file doesnt work, and if I do `\s` then it matches all whitespaces I think
karapetyan has joined #ruby
<elomatreb>
just a space matches a space, unless you set the x modifier
<hk238>
pontiki how would I do it with regexp? :o
<pontiki>
oh, you're not talking about ruby
<elomatreb>
If you're using backslashes, are you sure you're not using regular expressions?
<hk238>
it's a ruby regexp, but for some reaso nin thisthing it doesnt work if it ends in a space, so it's problematic
<hk238>
(or at least it's claiming to be ruby)
<pontiki>
sublime text doesn't use ruby
<elomatreb>
ST usually is Python
alfiemax has quit [Ping timeout: 252 seconds]
<hk238>
oh
Tachikomas has quit [Remote host closed the connection]
<hk238>
on the off chance that it actually is ruby,
SilverKey has quit [Quit: Halted.]
<elomatreb>
But "simple" regular expressions are usually the same across languages, as they're all inspired by Perl
<hk238>
if for some reason sublime wouldnt process a match correctly when it ends in a `\ ` that is a backslash, and a literal space, how would I match whitespace differently?
<elomatreb>
Have you escaped your backslash in the regex?
<hk238>
nope

it seems to work now, well, the at least there's no error, the syntax definition doesnt work, but I think that's not about the regular expression so it should be a different issue..

The_Phoenix has quit [Quit: Leaving.]
<hk238>
actually it is a problem with it, there's no error once escaping the backslash, but it's not matching the whitespace
<pontiki>
i wonder who owns that doc. the link where it says Ruby looks pretty funky
<hk238>
I mean I tried it with `\s` and it matches a whitespace
<pontiki>
\s matches any sort of whitespace
<hk238>
yeah that's the problem :d
daumie has joined #ruby
<hk238>
or I assumed it would be a problem so I didnt try that
<pontiki>
if you only want it to match "space", don't say "whitespace"
<elomatreb>
If you just want to match the regular space, a regular space should work. Unless you ended up with some weird unicode space in your data or regex?

pontiki, i've set out to create a parser for ruby in the same way esprima is for javascript
<pard>
but it is going to be somewhat more demanding
<pontiki>
there's currently a transpiler project that converts ruby to javascript (opals), but if ruby could be parsed in the browser, that might pique someone's interest
<pard>
pontiki, thanks

so would it be worth the effort?

First of all, let me start by saying that I am new to Ruby. I am working through Chris Pine's "Learn to Program" and am trying to write some code to get input from a user (their age, as an integer), and convert that to an approximate number of seconds. My output does not match up with what other converter programs online say it should be, and I cannot figure out why. Here is my source code: http://pastebin.com/34YF8GzH
<bougyman>
I called DateTime.now twice, it would be a little different
<bougyman>
that's the expected, correct behavior
<adaedra>
ah yes, that too.
* adaedra
is a bit tired
<bougyman>
in ruby 1.8 i'm trying to get seconds between one DateTime and another.
<travisxcode>
hxegon: I am expecting 662,695,992 Seconds (using 21 ase the age).
<bougyman>
and it's no big deal, I wrote my own .to_time for 1.8 before
<hxegon>
travisxcode: their age in seconds? (also on line 14 you don't have to do #to_s for age_in_years, because puts automatically calls #to_s on input)
<bougyman>
it's just taht... I was trying it in a one-liner.
<travisxcode>
hxegon: That was my problem! Thank you! I'm looking forward to learning more about programming over the next...well, hopefully the rest of my life!
<hxegon>
travisxcode: it's pretty interesting stuff. Pick up a copy of Practical Object Oriented Design in Ruby, when you get a chance

chignon what the various attr*s do is as you can write in ruby code yourself: attr_reader :foo is the same as: def foo; @foo; end; attr_writer :foo is the same as def foo=(i); @foo = i; end and attr_accessor combines the two into one

.foo is a method call that will work if the object responds to this method; if you used an attr* there then this will have added a method with the name (or with the = variant if you use attr_writer)

these are examples!

@jottr np
<shevy>
your code
<shevy>
foo.bar = 'value' # also a method invocation
<shevy>
if you write this on your own, you would use: def bar=(input1, input2, input3)

but I still don't get the concept of needing @name = assignment in 1 and not in the other
SCHAAP137 has joined #ruby
<chignon>
or rather @instance_variable = parameter in 2nd script and not needing it in the 1st (assume I utilize 2 objects/instances)
<shevy>
you already manually set the values in your own code
<shevy>
like via buddy.name
<shevy>
the object that you pass in responds to .name
<chignon>
@shevy yeah...I have to

same with @what_animal

Dog = Animal.new; Dog.what_animal = "Dog"
roshanavand has joined #ruby
<chignon>
@shevy but @breed = personality ? that's only in my 2nd script
<shevy>
well
<shevy>
why do you redefine class Dog anyway
<shevy>
where did you even get the Dog = Foo.new part
<toretore>
chignon: the code you're working with is very poor quality, if you're getting it directly from some book or tutorial you should stop following it

@toretore ... that code is my own brew if u will. I was p[layign around with code
ghr has joined #ruby
<toretore>
chignon: then you're a few steps ahead of what you should be doing. understand the basics first
<shevy>
but you really really should not redefine the classes you wrote prior to that. there is no need to use Dog = Dog.new as opposed to dog = Dog.new; or better, use the example code I showed above adam = Dog.new('Adam', 'alpha')

I've done `bundler gem --test=rspec currency_utils` to set up the project structure, and added a class inside the module it generated. I'm having trouble exercising the code in irb. uninitialized constant -- it's not loaded.

wsmoak: do you understand how loading files in ruby works?
pawnbox has quit [Ping timeout: 272 seconds]
<toretore>
there is no such thing as "requiring a gem"
<toretore>
you require files; ruby searches for those files in a list of directories, the load path
Xeago__ has quit [Remote host closed the connection]
<wsmoak>
I have a tentative grasp of 'require' and LOAD_PATH, yes
<toretore>
ok, so you have a directory from which you'd like to load some files
<toretore>
these files must then be in the load path
<toretore>
yes, but you're not dealing with a gem, you just want to load a file

the project itself is a gem. If I try to `load 'lib/currency_utils.rb'`in irb , it chokes on the `require "currency_utils/version"`that was generated.
<toretore>
it's not a gem until you package it up as a gem
<toretore>
you just have a bunch of files at this point
ghr has quit [Ping timeout: 240 seconds]
<wsmoak>
correct. how do gem developers deal with this? I'm sure this is a solved problem...
<toretore>
it's not a problem, and it has nothing to do with gems
<toretore>
forget about the gems

you have: some files, in some directories; you want: to load these files; ruby has `load` and `require` which searches for files in the load path
