Hi! Why do you think Ruby has enjoyed such popularity as of the late 5 years? It's quite amazing
<rking>
patrick99e99: I got an rspec test bed set up, so now I can try to make something like your code work.
<billiamii>
Testing isn't bearing that out, though, so I dunno
<mikeg>
my last try was this: connection.put_object("imchat_development_logs","ready/logmover.conf",File.read("logmover.conf"),options = { 'Content-MD5' => "f81a724a1bf0a87f3fe7ef3995f3dd62"})

actually there was a lot of off topic stuff recently you're fine

when i write a loop like a " while code , my code , end" i see some examples uses : "while code DO, my code , end" in both case is the same? or i should use do always?

So, it might fail if going up the directory tree, like File.dirname(__FILE__)+"/../foo" but it should still work either way for just +"/foo".
medik has joined #ruby
<Alantas>
On the interpretation that __FILE__ returns whatever it needs to return such that feeding it into 'require' produces the right result.
<Alantas>
Whether it be relative to the working directory, or whatever.
<bnagy>
require_relative uses File.dirname(caller[0]) which will be absolute
jobicoppola has quit [Ping timeout: 245 seconds]
<Hanmac>
Alantas the working directory is kicked out of the loads, so relative to the working dir does not work
<bnagy>
my way won't work if you give a relative path that's not in the script's dir, but will work if you give an absolute path, or ~/stuff/bin path etc
<bnagy>
Hanmac: it will work fine if you're in the script's dir
<bnagy>
because you'll end up with require './foo'
<Hanmac>
yeah ... and what if not??
<bnagy>
then read what I just typed
<Alantas>
Yeah, File.dirname(__FILE__) produces different literal results depending on what directory the script is called from: so that the same final result is gotten. Which is the whole point.
hoelzro|away is now known as hoelzro
<bnagy>
if you're next to it or if you give it an absolute path (or a shell expanded path like ~/blah/) then it works
<Hanmac>
"it will work fine if you're in the script's dir" and if the interpreter is NOT in the scripts dir, your whole system fails?
<Alantas>
As long as you don't Dir.chdir between the __FILE__ and the require, I don't see how it can be a problem.
<bnagy>
or if you give it an absolute path
<bnagy>
I think it's time for your meds, dude
jjp has joined #ruby
<bnagy>
if the app you're running is a) in your path b) you're in it's working dir or c) you give an absolute path to it -> all is well
<bnagy>
when you give a relative path and you're not in the dir, it will not work
<bnagy>
which is what I said about 10 minutes ago
<bnagy>
all of which was in response to an assertion about hijacking, which never went anywhere

Vista ... it was a lot of half compleated ideas with broad ramifications (annoying UAC, UI choices that are unreversable as had been the case in previous windows) that windows 7 refined. UAC in 7 is less ubtrusive, and the ui is more flexible

Ballmer has to apease investors. Yes, Vista made the most money on release as any windows.. it has nothing to do with the OS, and more to do with the fact that in 2007 more computers were purchased than 2001 when xp came out

<[Tritium]>
but honestly... I would just not care about this IF all the distros did it the same
<shevy>
distros can not even use the same scheme to name their -dev packages :(
<shevy>
my conclusion is that they purposely like to remain incompatible to one another

redhat may have that goal, but i dont see slack or debian ascribing to that

Mozilla had some protections in the license about their trademarks

<shevy>
hmm
<[Tritium]>
the protections prevented debian from shipping patches in a timly manor... have you ever known debian to be faster than mozilla at anything?

what about google chrome browser, can you use that on debian, or is it renamed too?

like how the guys with machomebrew update their recipes
<[Tritium]>
you could only call your distro firefox if it was on the same codebase, with no excessive patching, debian changed the name... and have not actually patched it ever
<shevy>
also, no separation between user and developer. I think everyone should have the same rights, more or less, to modify something (of course the modification must be an improve, no spoilsports assumed here)
<shevy>
[Tritium] hmm that means, if there are bugs in firefox, and I distribute that, and if I patch the bugs, I may no longer use the name firefox for the resulting binary?

If you find a bug and patch it..and dont submit the bug to mozilla... maybe? mozilla is more woried about breaking compatibility and featuresets

<banisterfiend>
you'd have to relearn how to program in the new paradigm

<workmad3>
bnagy: one of the domains is in the third column
<workmad3>
bnagy: which contains a ms time in other places
<bnagy>
workmad3: oooh, crap, yeah ok, but it's max three misses
<Tensibai>
not always
<vectorshelve>
workmad3: ruby is intepreted (line by line) unlike java which in compiled (whole code into byte code)
<Tensibai>
and maybe the 4the or fifth filed
<workmad3>
vectorshelve: not quite nowadays
<vectorshelve>
shevy: what was it before YARV ?
<workmad3>
vectorshelve: YARV nowadays compiles the entire program into bytecode
<Tensibai>
(Max retry to icmp echo the hop=
<vectorshelve>
workmad3: so u mean ruby isnt interpreted any more ?
<workmad3>
vectorshelve: but it doesn't save the bytecode anyway
<workmad3>
vectorshelve: it's... fuzzy
<vectorshelve>
workmad3: ruby 1.9.3 ?
<workmad3>
vectorshelve: and it's not a useful distinction
<vectorshelve>
workmad3: then why did I get an error calling a function in line 20 of my ruby class when it implemented functions in line 1 to 10 and the error was that I had a unnecessary symbol above line 20
ronniy has joined #ruby
<bnagy>
ok, I'll upgrade to 'easy' cause you have to check more than one column
<Tensibai>
lol bnagy
<workmad3>
bnagy: it's a pretty simple parser, yes :) it's a bloody nightmare with pure regex
<vectorshelve>
workmad3: then we need to compile it each time before running ? isnt that wierd
<workmad3>
vectorshelve: I repeat... it's fuzzy and not a useful distinction :)
<Tensibai>

the user will need a ruby binary of some sorts to execute ruby code

With RMagick, how can I apply a mask on an image so the pixels overlapping with the black area become transparents?
<vectorshelve>
shevy: right... then why ppl use this word ruby compiler all the time.. its so misleading isnt it ?
<shevy>
still on rmagick ;)
<Tensibai>
bnagy: indeed, you may find a readable regexp matching 80% usual cases
<bnagy>
like * * is abort and any /[0-9\.]+/ is abort
<Sephi-Chan>
Yep, back ^^
<shevy>
vectorshelve, you must have read it somewhere
jcromartie has joined #ruby
<workmad3>
vectorshelve: it's not a useful distinction these days with the prevalence of VM-based bytecode languages (which don't really fit into the compiled/interpreted binary view of the world)
<vectorshelve>
shevy: yes
<shevy>
vectorshelve, the internet is a place with lots of greatness and lots of evilness :)
<vectorshelve>
workmad3: so what is this ruby binary essentially ?
<bnagy>
Tensibai: but the parser is easier to write, read and will always work :)
<workmad3>
shevy: by that definition, java is an interpreted language :)

yeah the repl output shows "\\/dev\\/nul\\/" but if you call puts it'll output what you expect
JohnBat26 has joined #ruby
<Alantas>
Oh, yeah, I get it now. You're sending one to puts() and calling .inspect() on the other (irb does that on the values an expression evaluates to), and .inspect() would be escaping your backslashes.
blue_ has quit [Remote host closed the connection]
<Alantas>
If you do puts() on both, it should show that it always worked as expected.

Or don't do puts() on either one, and they should still come out the same as each other.

I was already writing Perl 6 programs when I switched to Ruby in 2004.

The chances that "no one will be using Ruby" in "about 10 years" are the same as the chances that a giant space rock will wipe out human life and there won't be any survivors. 10 years, I'd expect even a Mad Max world to still have a few of us in caves with batteries and bicycle generators plugging away at some Ruby code

is there an easy way to initialize a struct from an array (the array has the exact number of structure members)? I tried MyStruct.new(myary) but that put everything in to the first member
<fowl>
MyStruct.new(*myary)

will cause myary to expand into arguments

Hi guys. What's a good way to split a hash into two? Right now I am using x.delete_if{|k, v| v.class == Regexp } and a.delete_if{|k, v| v.class == String }

to define one of the hashes, but it feels very sloppy because I have to define x and a, even though they are both the same hash to begin with

jeebster: I get the feeling that you're doing something in ruby that your db should do…
<apeiros_>
are those objects AR models?
<jeebster>
so I have to loop through both sets, but it would be nice if each instance of the first could check the second
<jeebster>
apeiros: yes
<jeebster>
so basically, I'm trying to create records from an API call and I don't want to duplicate existing records
<apeiros_>
and is it indeed the id column on both arrays? or is it id on one and foreign-key on other?
sick_protoman has quit [Read error: Connection reset by peer]
linus95014 has joined #ruby

The tables are not connected. I have a table in my db that holds an ID value to reference the object in another db
<jeebster>
I'm using the id to associate the records
<apeiros_>
use an exists query
<jeebster>
I prefer to keep this in ruby if possible. any other way or must I resort to sql?
<apeiros_>
much faster than getting all the records, mapping for their ip, intersecting and checking for emptiness.

I'm seeing different string behavior between 1.9.2 and 1.9.3. A single-quoted string with a single backslash followed by a utf-8 character loses the backslash in 1.9.3, whereas in 1.9.2 it's the same as '\x'.

In other words, '\Յ' and '\\Յ' are not the same in 1.9.3 but were in 1.9.2.

Does anyone know why? Is it intentional? I didn't see it in the changelog...

I want to do something like this, but I want to point the 3 pipes of the subprocess to a log file, any ideas? (pid = fork) ? Process.detach(pid) : exec("foo")

lectrick: look at popen(2) and IO.reopen
<davidpk>
lectrick: my bad, popen(3)
<davidpk>
lectrick: you might be able to do what you want with IO.popen, but also look at the open3 module in the standard library if you need more flexibility

what's the best way to log variables? it's annoying i have to write the var name twice - any way to output without saying, e.g. "expr: #{expr}"
