I am having trouble installing bundler on Mountain Lion. I started with the CLI then switched to using the RVM GUI and it says it installs yet I cannot access the commands, gem says it isn't installed.

karstensrage: the repository you have there is how an example application using devise could look like, but most likely not something to continue building from
digitalcakestudi has quit [Ping timeout: 246 seconds]
<karstensrage>
not something? or something to continue building from?
<burgestrand>
karstensrage: not something to continue building from, but rather something to look at to see of how you could use devise
<burgestrand>
karstensrage: kind of like a blueprint
<karstensrage>
ok i see
<burgestrand>
karstensrage: for example, it is using a slightly older version of rails than you should use when starting a new application, especially if you are new to rails in general, since the current guide material for rails is for newer versions
<karstensrage>
rails is like the framework, right?
<burgestrand>
it’s not *really* old, but slightly out of date :)
g33k has joined #ruby
<karstensrage>
it says i have ruby 1.8.7 and WEBrick 1.3.1
<karstensrage>
oh
<burgestrand>
karstensrage: yes, rails kind of enforces a structure on how you should write your code, and where you should put your code, in order to help you build web applications faster and in a good way
<karstensrage>
and Rails 3.0.10
guns has quit [Ping timeout: 244 seconds]
<burgestrand>
karstensrage: yes :) that is because of the file named Gemfile in that repository, it tells your application which gems (libraries) and versions you should use when running the application
zz_fbernier has joined #ruby
<karstensrage>
oh i see yes
<karstensrage>
and 3.0.10 is old?
<burgestrand>
karstensrage: together with the Gemfile.lock file, it is the single authorative documentation of what versions that application can use
<burgestrand>
karstensrage: yes, not very old, but we have version 3.2 now, which is the most recent one
zz_fbernier is now known as fbernier
<karstensrage>
gotcha
<burgestrand>
karstensrage: new releases often come with new features, and many guides may use some of these new features, which means that if you follow a new guide with an old version, you might get confused

<karstensrage>
yup
<karstensrage>
mostly java, php, some python and i cut my teeth on symbolics lisp and C programming
<burgestrand>
sounds like a good arsenal, ruby has many similarities to python, more so than the other languages you know from earlier, but has a very different culture and structure in it’s applications
answer_42 has joined #ruby

would you recommend a good intro from my background to introduce me to the culture and structure aspects?

<bnagy>
well if you enter "\x61" you'll just get 'a'
<fowl>
>> "a" == "\x61"
<al2o3cr>
(TrueClass) true
<bnagy>
you can convert to hex a few ways, depending on what you want the output to look like
<alphoro>
fowl: yess I want to convert char to hex so it is the same
<fowl>
alphoro: it _is_ the same
dhruvasagar has joined #ruby

I have a string like "azereazrfezat" and I want to get a chain like "\x61\x......"
<bnagy>
"foo" is 3 bytes "\x66\x6f\x6f" is 3 bytes

"\\x66\\x6f\\x6f" is 12 bytes

alphoro: are you thick?
<alphoro>
fowl: no , just try to understand how to get my result :)
<alphoro>
I need to use Zlib::Inflate.inflate(compressed) ( where compressed is \x... and I cannot put directly the string)
<fowl>
alphoro: then why arent you reading what the people who are trying to help you are saying
matrixise has joined #ruby
<bnagy>
alphoro: ok, you need to explain exactly what you want, because if you want a string representation of the hex values, that will not be the same
Mister5 has quit [Quit: Leaving]
Takehiro has quit [Ping timeout: 240 seconds]
<bnagy>
as far as ruby is concerned 'A' and 0x41 and 65 are all exactly the same thing
<bnagy>
it's just a byte
luckyruby has joined #ruby

if you want to display a backslash, an x and a 4 and a 1, that's gonna be 4 bytes

<fowl>
what i do when working with bytes, (just to display them!) something like str.bytes.map {|b| b.to_s(16)}.join' '
<bnagy>
alphoro: you're mistaken

I odn't know what you're problem is, but that's not it

well we assume he's not actually trying to inflate 'aaa' :P

see how it comes out with with characters like x, K, L, J

sooo
<bnagy>
to be honest, I don't really trust Zlib, had it break on some valid stuff before

you should test shelling out to gunzip

Of course I can check this with a simple if condition but if I remember correctly (was some time ago I used ruby) there should be like x = y || do.. something something that returns the reduce. anyone catch what I am after?

Also, when you do reduce({}), it's likely you will be mutating the hash instead of changing the accumulator
<Mon_Ouie>
So you might as well use #each_with_object

reduce is not when you want to mutate a specific object, it's when you want to return a new accumulator after each iteration
<Mon_Ouie>
e.g. inject { |acc, e| acc + e }
beneggett has joined #ruby
<Mon_Ouie>
It looks awkward when you use it for mutating: inject({}) { |h, e| h[e] = stuff; h }
savage- has quit [Remote host closed the connection]

Xeago: I understand that bit, where I am getting confused is self is typically a receiver of messages but I've seen it used as an argument (see pastie). Just wanting to know why not simply map blog.add_entry(post) vs. the blog.add_entry(self)

because post is not a variable in your context

so because add_entry is a method from Blog the method add_entry is effectively grabbing a post obj from the correct domain (e.g. Post)

Hi, noobie question. I'm trying to use String.insert and to_s at the same time.
ph^ has quit [Read error: Connection reset by peer]
Moggle has quit [Ping timeout: 264 seconds]
<shevy>
you modify the string object via .insert
ph^ has joined #ruby
<shevy>
if you have a variable, and want to build it up slowly, for some reason, step by step
<shevy>
you could do:
<shevy>
x = "foo"
<shevy>
x.insert 5,'lo'
<shevy>
x.insert -5,'ack '
<shevy>
x << 'yippie ey yoh'
<shevy>
new_var = "hi#{x}"

<blazes816>
joofsh: but looking above you probably just want output = Fil e.new(filename,"w")

blaze816: It will work that way, but then it creates 20 files in my main directory, its really messy
<blazes816>
?
<Hanmac>
joofsh read about File.open , File.new is maybe not soo good
<canton7>
joofsh, the filename variable is "output/thanks_<stuff>/html"
<shevy>
kenneth well perhaps ruby doesnt like that construct you try to use :D
machty has joined #ruby
alanp_ has joined #ruby
<canton7>
joofsh, thus, the files will go in output/
statarb3 has quit [Quit: Leaving]
<joofsh>
hanmac: okay i'll look into FIle.open
<Hanmac>
joofsh and change "letter = File.open("form_letter.html", "r").read" to "letter = File.read("form_letter.html", "r")" ...
<Hanmac>
using open without an block and without close is a very bad idea

No such file or directory - output/thanks_Nguyen_Allison.html (Errno::ENOENT)
dagnachewa has joined #ruby
<joofsh>
but I already do have a directory output. Just not the file yet, hence I wanted to create it
<canton7>
joofsh, then changing line 106 to 'File.new(filename, "w")' should work fine
<canton7>
make sure the 'output' folder exists first
<fowl>
"w+"
<canton7>
File.mkdir('output')
carrythezero has joined #ruby
<Hanmac>
like that File.write(filename,output)
recycle has joined #ruby
<joofsh>
oh, hmm
e is now known as root
<fowl>
ah w+ is r/w i thoguht it was read/create but w does that
<canton7>
yeah
<Hanmac>
canton7 not tell him that he should use File.new(filename, "w"), in 99,99% there are better ways
hukl has joined #ruby
<joofsh>
hmm
<canton7>
joofsh, next point: use File.new(filename, "w"){ |f| f.write(custom_letter) } also
<canton7>
oops. File.open not File.new
<joofsh>
File.mkdir('output') gives me an error. says mkdir method does not exist for File?
<joofsh>
canton7, good call, that's much cleaner. Hadn't gotten there yet
<canton7>
so File.open(filename, "w"){ |f| f.write(custom_letter }
<canton7>
that takes care of closing the file
hukl has quit [Client Quit]
<canton7>
and I'm an idiot. it's Dir.mkdir
minijupe has joined #ruby
<Hanmac>
canton7 yes you are :P
* canton7
bows his head. been too long since I did file manipulation in ruby
<canton7>
in general, using File.new is bad, and using File.open without a block is bad
<joofsh>
lol, sorry this is so irregular to do file manipulation in ruby
minijupe has quit [Client Quit]
<Hanmac>
"File.write(filename,custom_letter)" is the same as "File.open(filename, "w"){ |f| f.write(custom_letter) }"
<canton7>
nah it's perfectly fine and natural
<fowl>
joofsh: actually it isnt, its like every other language, open a file, read/write to it, close it
<canton7>
Hanmac, aha good call thanks. joofsh ^^
<joofsh>
will File.write() also create the file like open will?
<Hanmac>
but unlike other languages ruby can close the files for you automaticly if you use the right methods /arguments
<Hanmac>
joofsh yeah
<Hanmac>
fowl: no w+ is not like r/w ... w+ means that its running in "add"-mode
<fowl>
Hanmac: no it doesnt :)
sonkei has quit [Quit: Computer has gone to sleep.]
<canton7>
w is overwrite iirc. a is append
<joofsh>
Okay cool, File.write(filename, custom_letter) works really smoothly. But I still can only get it to write to the main directory. if I set Dir.mkdir('output') it gives me `mkdir': File exists - output (Errno::EEXIST)
<blazes816>
Hanmac: you're thinking of 'a'
<fowl>
Hanmac: w and w+ will always truncate the file
<canton7>
joofsh, replace line 105 with filename = File.join('output', "thanks_#{line[:last_name]}_#{line[:first_name]}.html")
