<swarley> anyone want to tell me how to do an array of strings pointing to arrays of strings in sqlite?
<epochwolf> the same as you would with any sql database?
<swarley> no idea how to in any sql
* epochwolf blinks…
<epochwolf> no clue where to start explaining that, :/
<swarley> in ruby i have {"Hello World" => {"how" => 1, "other" => 43}}
<swarley> i want to try to make a database where i can use a similar structure
<swarley> if possible
<swarley> i guess i could make multiple tables
<cout> yep.
<epochwolf> that's a start
<swarley> can table names be multiword?
<fowl> o.o
<swarley> i dont think they can
<fowl> you mean "table a" i dont think so
<epochwolf> swarley: multiword?
<fowl> table_a would work though
<oooPaul> Do you want to represent the hash as a set of table rows, or do you just want to store the hash IN a database column?
<oooPaul> The ever-important-but-never-asked question is... Why do you want to do this? :)
mikeric has joined #ruby
<heftig> making a tree structure is quite easy, just needs ID and ParentID columns
<swarley> i have this working with a hash, but i'd like to use a database instead
<swarley> since the hash would get very large with a decent size text
<swarley> (its a markov chain text generator)
<heftig> oh, i wrote one of those
<heftig> uses hashes and saves them using Marshal
<oooPaul> If you just want to save a hash in a row, you can use serialize.
<oooPaul> (if you're using ActiveRecord, that is)
<Nisstyre> heftig: not as easy as in languages that allow algebraic data types
<Nisstyre> :)
<swarley> i've been playing with a few different storing algorithms, and i think this is the one im going to stick with. So now i need to find a good way to keep it from using 9000000000gb of ram

<seanstickle> banistergalaxy: hey, you have the down low on all the pry magic, right?
<banistergalaxy> seanstickle: Yeah
<seanstickle> banistergalaxy: how do I go about embedding pry into a Ruby script, so that I can do a bunch of stuff, and them drop the user into a pry session?
<banistergalaxy> seanstickle: just put `binding.pry` at the point u want to call it, that's to use it as a debugger, it'll display surrounding context from the point it's called
johnmilton has joined #ruby
<banistergalaxy> seanstickle: alternatively if u dont want to use it as a debugger just put `Pry.start` and it'll start a session at top-level (and not show surrounding context when it starts)
superguenter has joined #ruby
<banistergalaxy> seanstickle: or Pry.start(your_obj) to start it in the context of the specified object
<seanstickle> That is some perfect awesomeness.

sacarlson has joined #ruby
<banistergalaxy> seanstickle: oh ok cool, probably best to use `binding.pry` then, so u get access to any locals
libertyp1ime has joined #ruby
<arubin> banistergalaxy: Would you care to elaborate a bit on your previous explanation? Code similar to that in C would work fine and not because C is creating a closure.
<arubin> banistergalaxy: I am more than willing to read an in depth explanation.
<banistergalaxy> arubin: but in C the 'b' would be a global variable
Sailias has joined #ruby
<banistergalaxy> arubin: whereas it's not creating a global in ruby, it's just a top-level local
<arubin> What is the difference between "global" and "top-level"?
<banistergalaxy> arubin: a global is visible everywhere, a local is only visible at top level
<arubin> I realize that there is a difference in Ruby.
libertyp1ime has joined #ruby
rboyd has joined #ruby
<arubin> Let me approach this from a different angle.
<arubin> When I start the REPL what context or namespace am I in?
nvez has joined #ruby
<MasterBob> I'm confused on how to access data I captured in a regexp using ()
<banistergalaxy> arubin: TOPLEVEL_BINDING
<banistergalaxy> arubin: or a binding built on toplevel
<oooPaul> MasterBob, you mean using $1, $2, etc?
<MasterBob> Yeah.
<oooPaul> Just reference them. :)
<banistergalaxy> arubin: look, basically a 'def' creates a new scope, all locals that were present prior to the 'def' no longer are accessible inside the 'def'
<MasterBob> oooPaul: just $1 ? or is it regexp.$1 ?
<oooPaul> "foobar" =~ /(fo+)/; foo = $1
<oooPaul> Nope, they're globs.
<oooPaul> Just $1, $2, etc.
libertyp1ime has joined #ruby
<banistergalaxy> arubin: C doesn't have this issue cos it's impossible to define a function in C outside of "top level" and all variables defined at "top leveL" are global
<MasterBob> oooPaul: using named_captures will return a hash of all the captured items, yes?
<oooPaul> Not sure, never heard of it
libertyp1ime has joined #ruby
<oooPaul> Looks like it, though.

<uris> hi, ruby newbie here, trying to use rest-client gem : http://rubydoc.info/gems/rest-client/frames
<banistergalaxy> arubin: if u want to access b inside your method then rename it $b
<uris> but i get an error saying it cant find rest_client
<uris> i followed the example in the docs
<banistergalaxy> arubin: or you can force a method to be a closure by using define_singleton_method instead of 'def'
<MasterBob> So then should I used named_capture or names if I want to get all the captures?
<uris> i already installed rest-client: gem install rest-client
<banistergalaxy> define_singleton_method(:hello) { puts b }
<uris> and checked that it was indeed installed gem specification rest-client
<arubin> banistergalaxy: Sure. I am just trying to understand what Ruby is doing more than anything.
mneorr has joined #ruby
sohocoke has joined #ruby
mneorr has joined #ruby
<banistergalaxy> arubin: there are some strucutres in ruby that always create new scopes (causing extant locals to vanish), these are: def, class, and so on

<arubin> banistergalaxy: I think that I understand that much now. I am more curious where b actually is.

<shevy> Pxk ruby gtk
<undersc0re> >:
<undersc0re> shevy: NO
<undersc0re> ruby-gtk2 binding suck
<undersc0re> Tk or Qt
<shevy> undersc0re what do you suggest
<Pxk> okey so i need, ruby, then i need a visual interface, then i need install an exe converter,
<undersc0re> I personally prefer Tk for the simplicity
<shevy> undersc0re have you ever written in ruby-qt???
<undersc0re> shevy: ya
<Pxk> there is not any lenague with just downloading the programer be able to generate a visual program ? exe one
<undersc0re> the bindings aren't nearly as bad as the GTK2 bindings
<shevy> what is "lenague"
mneorr has joined #ruby
<undersc0re> lenague must be some type of foreign word
<shevy> and a "programer" what is that
<Pxk> amsn is programed with tk-gtk and it's cr*p, worst program ever, works very bad
<undersc0re> wtf is "tk-gtk"
<shevy> what is "cr*p"
<Pxk> language*
<shevy> Pxk, you need a new keyboard
<Pxk> cr*p = crap
<undersc0re> or, to spell stuff correctly
<shevy> ah the keyboard works better now
<fowl> chill out
<fowl> he already said he doesnt speak english
<undersc0re> yeah, i dunno what cr*p is
<fowl> talk about ruby you turds
<undersc0re> fowl: but he is right now!
<Pxk> i do speak english but is not my native lang, i try my best,
<shevy> :D
<Pxk> what about python or delphi ? they are more easy to programe a simple GUI for an easy ttask ?
<shevy> I think it must be the keyboard
<shevy> ttttttask!
<undersc0re> Pxk: you should like
<undersc0re> not learn Delphi
<uid0> is there a parameter I'm missing ?
<shevy> they like delphi because you build component programs
<undersc0re> uid0: What do you mean?
<Pxk> but Delphi can be exported to exe or its like perl?

<undersc0re> shevy: this is like the 4th time he's said that

<undersc0re> He hasn't sad anything helpful
<shevy> Pxk, see. You should pick a language that you know you will be using for a longer while.
<undersc0re> s/sad/said/
<shevy> Whether it is delphi/perl/python/ruby does not matter. There is no silver bullet to solve all your problems in one day either.
<shevy> But choose wisely.
<undersc0re> ^Exactly
<Pxk> i dont like programing shevy, i am just looking for some lightweight "all in one" compiler that allow me to create a visual exe quick and easy for an easy task, just generate a txt file with some numbers depending on the info selected
<shevy> ok, pick delphi
<shevy> you also won't like it but that's ok since you don't like programming anyway
<fowl> uid0: is there a parameter I'm missing?
<shevy> lol
<Pxk> i just like php, css, and so on
<Pxk> i hate java
<Pxk> and object based programing
<shevy> hey
<shevy> I thought you dont like programming
<shevy> why do you like php???
<Pxk> i just like it when i understand it i guess,
<fowl> Pxk: if you hate object oriented programming ruby's not your language
<Pxk> then ruby out of the list,
<Pxk> i read somewhere it was very easy
<shevy> you read wrong
<shevy> ruby requires thinking powers
<shevy> php does not
<shevy> delphi even less so
<Pxk> delphi is easier than php you mean?
<shevy> I find php very hard
<uid0> is there a parameter I'm missing ?
<Pxk> seriously?
<fowl> uid0: is there a parameter I'm missing?
cmasseraf has joined #ruby

<shevy> uid0: I am missing ur mom
<fowl> uid0: maybe you're missing a parameter
<shevy> uid0: you dont miss a parameter
<fowl> in soviet russia, parameter misses you?
<Pxk> but take a look shevy, you need 3 compilers to generate a visual exe with ruby, php is just notepad and done
<shevy> Pxk wah
<fowl> then use php, there's probably GTK bindings for it
<fowl> in any case please stop talking about non-ruby in here
<fowl> it's not kosher bro
<shevy> Pxk what is the difference with ruby and php?
<Pxk> can i make an exe with php code
<shevy> I think you are looking at the wrong language still
<Pxk> php is not compiled
<shevy> go use delphi, father 20 children and be happy
<shevy> and ruby is compiled?
<uid0> is there a parameter I'm missing ?
<Pxk> is not?
<shevy> where do you get your information Pxk?
<Pxk> i jsut guess it,
<shevy> I mean

<shevy> aaaaah :)

<The_Tick> indeed
<shevy> but admit it

<shevy> it was a simple problem ;P

<The_Tick> and it's more or less for copying files from source to destination
<The_Tick> shevy: i'm typing :)

<The_Tick> oh it does now
<The_Tick> in that second paste, works great
<The_Tick> I'd like to make it dynamic though
<The_Tick> so that I can have pl = pl at some point
<The_Tick> or more like, zh_TW = zh-Hant
<The_Tick> so I'd like to read the right docs for what I need
<The_Tick> but I don't know what I need
<shevy> what is your current code
<shevy> you never link to pastie so far :(
* The_Tick did earlier
<shevy> 100 years ago!
<The_Tick> ya :)
<shevy> value = ENV[name.to_s] <--- I thinkt hat is tainted
<shevy> when it comes from ENV
<shevy> also why do you use so many $
<The_Tick> I don't even know if I need that, I copied it from a build script I already have
<The_Tick> shevy: because I was trying to figure out why it wouldn't work, then figured out I misspelled one
<The_Tick> but honestly I don't know what I'm doing
* The_Tick has no problem admitting that
<shevy> well the $ is not needed in the example there right?
<The_Tick> in theory I could just have typed the path
<The_Tick> but I figured I could start learning ruby
<shevy> that is all nice and not, I am just wondering about the various $, you can remove them all
<shevy> also
<shevy> env_default is not actually used at all?
<The_Tick> no
<The_Tick> it can go
<shevy> I think you probably have not made up your mind yet about what you need :)
<The_Tick> probably true
<The_Tick> I was more figuring out how things work
<shevy> you should also be able to omit "FileUtils." if you do include FileUtils somewhere at the top I think
<The_Tick> I could have 2 $variables (those are variables right?) and tat's it
<shevy> $foo are variables yes
<shevy> but so is
<shevy> foo
<shevy> too
<shevy> :)
<shevy> $foo is just globally available
<The_Tick> wait
<The_Tick> ah ok
<shevy> it will become very annoying when you use several .rb files
<shevy> also it looks ugly. and uses one extra char
milkshakes has joined #ruby
<The_Tick> ok, so a non-global is just foo=bar
<The_Tick> and a global is $foo=bar
<rippa> 1,3,5,7-tetracarbomethoxybicyclo[3.3.1]nonane-2,6-dione
<The_Tick> honestly this is so much better than a makefile :)
<shevy> The_Tick yea
<shevy> well
<shevy> right now it looks 200% uglier than it should be
<The_Tick> well sure
<shevy> and makefiles are so ugly
<shevy> but .m4 is uglier

<fowl> whats wrong dir Dir.pwd
<shevy> yeah that is the next thing, Dir.pwd would be shorter

<The_Tick> does that $growl_bezel_display_strings require the $
fcoury has joined #ruby
<The_Tick> or does the #{} indicate that it's a variable and the $ just means that it's the global?
<shevy> the $ annoys me
<The_Tick> heh, so it's not required?
<shevy> #{} will just substitute
<The_Tick> ah ok
<shevy> foo = "Hi there."; puts "Hmm... #{foo}"
<shevy> $foo = "Hi there."; puts "Hmm... #{$foo}"
<rippa> （　´_ゝ`）
<shevy> but you see, the $ is totally useless and ugly here
<shevy> so please kill the $
ziyadb has joined #ruby
<The_Tick> oh those are going
<shevy> with #{} ruby expands the values inside

<shevy> you can also call methods there
<rippa> $foo = "Hi there."; puts "Hmm... #$foo"
<The_Tick> yay
<shevy> def foo
<The_Tick> that's awesome
<rippa> works too
<shevy> return "oki dokie"
<shevy> end
<shevy> puts "hmm... #{foo}"
<shevy> oh true
<banistergalaxy> shevy: what is your opinion of the abbreviaion "okies" for "okay"
<shevy> you can omit the #{} sometimes as rippa showed you
<shevy> banistergalaxy if you are gay, keep on using it
<shevy> english is overrated
<shevy> we must all learn german
<The_Tick> alright, I have to go
<The_Tick> but this gives me a lot to work with
<The_Tick> is there a good book to read on ruby?
<The_Tick> not rails, just ruby
<shevy> The_Tick hmmm... best way to learn is really to just write scripts
<shevy> pickaxe 2 was good
<shevy> the current one I dont like as much as the one before :\
<The_Tick> shevy: ya, that's my plan
<The_Tick> but worth asking usually
<shevy> I feel things got diluted from the switch to ruby 1.9.x

<shevy> ruby 1.8.x I loved

<Geniack> anyone familiar with running watir on different hosts (e.g. linux / windows / osx) ?
<banistergalaxy> A124: just replace it with a method that counts to 10 or something
<A124> banistergalaxy: Ah. Thanks. But I mean the transcoding issue.
<banistergalaxy> no idea

<workmad3> A124: on my machine, 1.9.3-p0 is 0.2s faster than 1.8.7
<workmad3> roughly the same with p125
<A124> QUOTE: banistergalaxy: workmad3: you're convinced it's all lies to impress and make friends /QUOTE .. This was regarding me?
<workmad3> A124: I just wanted to see if the results were reproducible personally :)
<A124> workmad3: So .. it's interesting. I have rvm compiled binaries.. so it's really strange
<workmad3> yeah, I have the same, MBP (late 2008) with 4gb ram, rvm binaries and an SSD
<A124> workmad3: No, no ofence, of course. And you did not also wrote that.
<A124> With this "workload + calls" code I got 0.6 and 1.4 respectively
<blast_hardcheese> Wow. Apparently gem is completely useless without rake; Everything I wanted to install depended on eventmachine, and eventmachine has an undocumented (or at least unenforced) dependency on rake.
<banistergalaxy> blast_hardcheese: Yeah, 'rake' is pretty much a given for ruby and it should come bundled with 1.9+

<A124> workmad3: Do you have any clue why it's slower a lot more for me thatn for you? Also, do you have any tip how to disable external transcoding?
<workmad3> A124: no idea... but I'm also thinking 'at least you're not on jruby, where that same thing took over 6s :) '
<A124> workmad3: :D LoL... Thanks for informing me.
<Tasser> banistergalaxy, ... and ugly ^^

<workmad3> :)
<workmad3> still an interesting result... why is IRB slower in 1.9.3? what extra is it doing?

<apeiros_> not like that, no. you can use a couple of mechanisms for something similar:

tayy has joined #ruby
tingo has joined #ruby
<apeiros_> depending on what you really want to do: b = :puts; send(b, a)
<apeiros_> again depending on what you really want to do - being able to pass a block to a method solves most of such issues, see how all the Enumerable methods just accept a block to determine the details of how they work

ephemerian has joined #ruby
<banistergalaxy> burgestrand: what does it do
<burgestrand> banistergalaxy: yields to the block given to the current method with a set of parameters to pass to it
<banistergalaxy> burgestrand: different to rb_yield() ? i guess it doesnt wrap the parameters in an array
<burgestrand> banistergalaxy: rb_yield only takes a VALUE, rb_yield_values takes an int n, and then n VALUEs instead
<burgestrand> essentially a variadic rb_yield :)
<banistergalaxy> burgestrand: but i mean, if you have a block: { |x, y| } then rb_yield([1,2]) would be more or less equivalent to rb_yield_values(1, 2)

<LMolr> I'm writing an irc bot plugin (using cinch) to print some text every 10 seconds. So I listen the event :channel and I need to write in every loop iteration a message in the channel. How can I write a message in the channel?

<scalebyte> shadoi: ok il try looking into it thanks
<LMolr> shadoi: can I get the channel object from the :connect event?
stkowski has joined #ruby
<shadoi> scalebyte: it's likely just checking for the presence of each hash value instead of seeing if it's actually a false.

<apeiros_> fowl: yes, there is

<apeiros_> it's called lethargy :(
<fowl> lol
<fowl> apeiros_: the commands like show-method are essential for me
<apeiros_> fowl: I can imagine
<apeiros_> after all, I do .bbedit all the time
Amnesia has joined #ruby
<apeiros_> (opens methods in bbedit)
<workmad3> apeiros_: but in code... it's nice to look at a method call like some_method(something_else.another_method) and be able to just do some_method(p(something_else).another_method)
<apeiros_> workmad3: as said, I have Object#p for that
Ark22 has joined #ruby
<apeiros_> foo(bar.p.baz)
<apeiros_> I've had that for like 5y now…
<workmad3> apeiros_: yeah, good point, that works too :)
<apeiros_> workmad3: it's even easier
<apeiros_> wrapping p() around stuff is often quite annoying
<apeiros_> cursor moving and all…
Ark22 has quit [#ruby]
<apeiros_> .p is at one point, no finger-stretching to () either
<workmad3> apeiros_: for rails, I added in Kernel#ee recently too, which does 'raise obj.inspect'
* apeiros_ is a damn lazy doc
<apeiros_> *dog
<heftig> except "p" is private
<apeiros_> workmad3: hu? why raise?
stephenjudkins has joined #ruby
<apeiros_> heftig: except, not in my irb :-p
<workmad3> apeiros_: gives you an error trace exactly at that point, no need to scroll through the server log
jleitgeb has joined #ruby
<apeiros_> heftig: Kernel#p != Object#p in my irb
<workmad3> apeiros_: and spits it out in the browser rather than the terminal :)
baroquebobcat has joined #ruby
<heftig> foo(bar.tap{|x|p x}.baz)
<apeiros_> workmad3: yes, but why raise? why not just use caller?
<apeiros_> heftig: yeah, I'm sorry, but foo.p.baz *totally* kicks bar.tap { |x| p x }.baz' ass
<apeiros_> and it kicks p(bar).baz' ass still a bit
<workmad3> apeiros_: not quite following...
jamescotterill has joined #ruby
<apeiros_> it's odd, I've had a dir() method once, but it's gone missing from my irb…
<apeiros_> workmad3: raise will interrupt your app, is that intentional? if you just want a debug output…
<workmad3> apeiros_: ah, yeah... the interrupt is intentional :)
<workmad3> apeiros_: the rails stacktrace page gives you a pretty nice stacktrace, and means you only have the one thing you're interested in on the screen
<apeiros_> I added binding.irb_drop quite a while ago for that. (actually irb_drop(binding), the other I stole from pry, but pry came a good 1 or 2y after my irb_drop)
<apeiros_> workmad3: ah, with the folding and all
<apeiros_> I see
<apeiros_> you want the html

<apeiros_> a graphical debugger for ruby would still be nice…
<workmad3> apeiros_: pretty much, yeah :)
<apeiros_> and it wouldn't even be impossible :-/
<apeiros_> I mean you can attach to a ruby process with gdb
<workmad3> apeiros_: however, I think .ee would be better than ee() now you mention it :)
<apeiros_> I'd probably call it .splode
<apeiros_> just for shits & giggles
kaichanvong has joined #ruby
robcthegeek has joined #ruby
<workmad3> apeiros_: I'm too lazy to type .splode instead of .ee :P
<apeiros_> make a short-cut to it, I'd recommend cmd-ctrl-shift-e
<apeiros_> ;-D
<apeiros_> oh, I knew I had forgotten one - I meant: cmd-opt-ctrl-shift-e

<Azure> An opinion question: what would be the best way to backtrack something, as a command.
savage- has joined #ruby
<Azure> Collection+10?
<Azure> Collection-10?
<Azure> Taking into account that whatever Collection returns is the most current.

<patrick99e99> I have a funky split regex issue.. I am trying to split a string by the first character that is NOT a digit... and so I am doing: "123foobar".split(/[^\d]/) and I get: ["123"] ...
<patrick99e99> what is happening to the foobar?
<patrick99e99> I am expecting ["123", "foobar"]
moeSeth has joined #ruby
tds has joined #ruby
zakwilson has joined #ruby
<davidcelis> it goes away
<davidcelis> because f, o, o, b, a, r all match [^\d]
CoverSlide has joined #ruby
<davidcelis> it splits at every instance, not the first
<davidcelis> > "a-b-c-d-f".split("-")
<davidcelis> => ["a", "b", "c", "d", "f"]
<davidcelis> and removes that character
<davidcelis> so you are left with the digits, and nothing else
<apeiros_> patrick99e99: whats the desired result?
<davidcelis> ["123", "foobar"] apparently
<apeiros_> ["123", "foobar"] ?
<apeiros_> davidcelis: 7 years in this channel taught me not to play the guessing game…
<davidcelis> lol
chson_ has joined #ruby
<apeiros_> btw, split(regex, -1) removes the special cases split normally applies
arnaud_gp has joined #ruby
<apeiros_> so: "123foobar".split(/[^\d]/,-1) # => ["123", "", "", "", "", "", ""]
<apeiros_> those special cases of split threw me off sooo many times… totally annoying IMO.
<davidcelis> ah, that's good to know
<davidcelis> very good to know
<patrick99e99> apeiros_: but--- that still does not return the foobar string.. Why not?
<apeiros_> patrick99e99: davidcelis already explained you
<davidcelis> patrick99e99: like i said, .split REMOVES the match
<apeiros_> patrick99e99: "a-b-c-d-f".split("-") # => ["a", "b", "c", "d", "f"]
<apeiros_> you don't see any '-' in there either, right?
<davidcelis> in this case, any non-digit gets removed from your string
<apeiros_> because you told ruby to split on '-'
<patrick99e99> ahhhhhhhhhhhhhhhhhhhhhhhh... ok then .match is my friend for sure in this case then.
bingomanatee_ has joined #ruby
<apeiros_> and that's *on*, not *before* '-'
<patrick99e99> thank you
<apeiros_> same for your [^\d]
<apeiros_> btw., [^\d] == \D
<patrick99e99> cool
shevy has joined #ruby
<apeiros_> "a-b-c-d-f".split(/(?=-)/) # => ["a", "-b", "-c", "-d", "-f"]
<davidcelis> "123foobar".split(/(?=\D+)/)
<davidcelis> => ["123", "f", "o", "o", "b", "a", "r"]
<davidcelis> lol
<apeiros_> h
<apeiros_> hm
<apeiros_> why's \D+ not greedy there?
<apeiros_> could probably be considered a bug…
<davidcelis> didn't know about ?= though
<apeiros_> look arounds++
<apeiros_> it's got 3 sisters
<apeiros_> but 2 of them don't like variable length :(
<davidcelis> i think i've only used ?:
<davidcelis> where can i read more bout those?
<apeiros_> ?: is not a look-around
<fowl> does anybody know if redef made it into ruby 2.0
<davidcelis> hm
<apeiros_> davidcelis: wikipedia, or in the book 'mastering regular expressions'
<apeiros_> the name + regex should help with google too
<davidcelis> thanks
