<balki>
can i change a hash like {:this => "that"} to an associative argument list?
billiamii has quit [Remote host closed the connection]
<balki>
like method1(:this => that)
<samuelkadolph>
balki: Those are the same thing.
<balki>
instead of method1({:this => that})
<samuelkadolph>
You can omit the {} if the hash is an argument to a method
<balki>
no, because i'm trying to inject them into an *args with a bunch of other stuff
<balki>
i have the hash, i need to append to a list of arguments
<samuelkadolph>
Then append it

you're not a rails user though (neither am i) so it's probably irrelevant, and anyway looks like the best we'll get is a commented out thingy in the Gemfile

well GEE mr fusspot, if you're so fussy maybe read the Enumerable docs yourself?

although i suppose you mean partition is just group_by with the single step of making the hash into an array of two arrays

which i see

Bird in hand. Also, Pry was one of the first things I tried to install when I was trying rbenv / ruby 1.9.3 the other week. Didn't work. (Bunch of crap about redefining constants, then failing for lack of something Ruby has built-in (Readline).)
<Alantas>
Well, it installed, but didn't run, it just did that. ^

hrm, worked out of box with rbenv for me on 1.9.3

<Alantas>
"A select"?
<zizzyx>
the select method that works on hashes and arrays and etc, can it be used on ranges as well?

Oh. Yes.
<zizzyx>
or can i generate a range with a predicate, i.e. generate a list of all possible parents for this new node

It works on all Enumerable types, which includes Array, Hash and Range, among others.

if you're on Linux, I believe you get one signal handler per process (unless you use a special pthread function), and the thread the handler is invoked on is non-determinstic

but, I think that you can set a sigmask on inidividual threads, so you can assert that a signal gets sent to a particular thread

yoyoma, wrong hightlight my friend...
<Alantas>
Dunno if it's cross-platform, given all the method names named after characteristically-Unix things like "ln -f".
<Alantas>
But, they could be cross-platform implementations of those things.
<Alantas>
So, try it and see.

Is it possible to copy a gem from one installation to another?
<shevy>
makes it easier to rescue exceptions too
<shevy>
brzz all .gem files are stored in cache/ subdirectory too
<banisterfiend>
brzz: i thnk rvm has commnads for that
<shevy>
so you only have to copy that dir, or copy all the .gem in that dir, and install via "gem install bla.gem", or in ruby something like ... "fetch all .gem files, then invoke gem install on each"
<shevy>
brzz, by default the cache dir is /usr/lib/ruby/gems/1.8/cache/ for any installation from source into prefix /usr. some distributions like debian are funny and use /var/* something instead. (1.8 would be 1.9.1 for latest ruby)
<yoyoma>

<brzz>
Strange I got some error on executing gem install: ERROR: While executing gem ... (Errno::ENOENT)

bnagy the code works, what looks wrong about test

doest it create or modify the thing on the left or the right side?
Gavilan has left #ruby [#ruby]

the second is broken

it assigns instead of ==, typo
yoyoma has joined #ruby
<shevy>
rubynoob in the context of rescue, it assigns and makes a new variable called error
<workmad3>
rubynoob: in a method call, e.g. something like 'my_method :foo => "bar" ' then the => is simply part of an implicit hash
<workmad3>
rubynoob: in a rescue clause, it's a way of specifying the variable you want the exception object to be in (as shevy just said)
<bnagy>
zizzyx: oic, it's the block var :S nevermind (but that's a really bad block var)

afaik, that's the only two places where => is valid syntax

rubynoob can you pastie the context

<workmad3>
rubynoob: because puppet resources aren't ruby
<rubynoob>
they're not?!
<bnagy>
zizzyx: but normally you'd have an add_child method for this kind of thing
<yoyoma>
hi all, writing some script that does some rest api in json. I read contents of a file, dump it as json and post it to the server. once in a while i get exception "Uncaught exception: "\xC5" from ISO-8859-8 to UTF-8" on line "issuestr = JSON.dump(issue)". what should I do ? convert first to utf8 ?
<shevy>
ensure would not work like that anyway
<shevy>
in ruby
<bnagy>
called on the node you're adding the child to
<workmad3>
rubynoob: the framework is written in ruby, new resource types are written in ruby, but the puppet resource config is a custom DSL that puppet parses
<shevy>
workmad3 knows the most exotic things :)
<rubynoob>
its a puppet class file. maybe thats why it doesnt make any sense to me.
<workmad3>
shevy: well, I was setting up configuration management @ work, and I looked at puppet and chef... went with chef because I didn't want to learn the puppet DSL :)
<zizzyx>
the way the data was ordered made it weird i dunno, i'm not familiar with doing lookups on a tree

class ntp {}

so i just made a flatten method and looked nodes up that way

nlc has joined #ruby
<shevy>
am I confused or does PHP make using forms easier than ruby .cgi?
<workmad3>
shevy: well, if you have a DSL embedded in ruby then turing-completeness comes from the fact you can do normal ruby code inside it
<workmad3>
shevy: when you have an external DSL, well it can be implemented in any language, you just need a parser :)
lorandi has joined #ruby
<workmad3>
but yes, it's very easy to accidentally create a turing-complete DSL

however, I'd probably argue that if you could create ruby inside a DSL that isn't a DSL for creating compilers then you no longer have a DSL :)

cousine has joined #ruby
<shevy>
matled, hmmm not sure... I think you can get instance variables via get_instance* something... but local variables? hmmmmm
<hoelzro>
graspee: if you can access a caller's locals somehow, look up the locals under the given symbols and dump them
<shevy>
let's ask workmad3
<shevy>
workmad3, can we get local variables without eval?
FND has left #ruby [#ruby]
<graspee>
you can iterate through the instance variables of an object and get their names it seems yes
internet_user has joined #ruby
<graspee>
but that's not the same as being able to pass a variable and get its name printed out and its value
<graspee>
and local variables i would want too
<hoelzro>
graspee: debug print would print both the name and the value
<graspee>
you mean debugprint is a real fn?
<hoelzro>
you just have to deal with the fact that you can't just pass a variable
<hoelzro>
no
<graspee>
ok you're saying i would pass :y instead of y?
<hoelzro>
yes
<graspee>
hmm
<workmad3>
graspee: you could pass in the binding and probably interrogate it for variables
<thedonvaughn>
eval(Kernel::local_variables[0].to_s) works for me
<thedonvaughn>
randomly picking the first variable :)
theRoUS has joined #ruby
mikeycgto has joined #ruby
<workmad3>
graspee: something like debugprint(:variables => [:x, :y], :binding => binding) would (I think) give you enough to do it :)
<graspee>
that's almost as much typing as before though
<graspee>
i just wanted to not have to type the #{} stuff really
<thedonvaughn>
graspee: uhm
<graspee>
and this just gives me colons and square brackets in exchange
tomb_ has joined #ruby

theRoUS has quit [Client Quit]
theRoUS has joined #ruby
<shevy>
whoa
<shevy>
hey wait
<graspee>
i can probably do it with eval though
<graspee>
i could send a string like "x y xpos ypos"
<shevy>
!
<graspee>
then it could take the string, split on tokens, eval tehm and put the values in
<shevy>
evals everywhere
<shevy>
THEY ARE OUT OF CONTROL
<graspee>
it's debug stuff
<graspee>
it doesn't have to win awards for ze speed
<graspee>
they will get commented out when the code works
elux has joined #ruby
<shevy>
when I work in a larger ruby project, I usually keep one central debug variable that toggles the debug state
<shevy>
usually, it will be @debug, and either set to true or false
lorandi has joined #ruby
<shevy>
so I can just toggle it
<graspee>
if only ruby had a preprocessor

<workmad3>
graspee: eval 'puts "' + binding.send(:local_variables).reject{|v| v == :_}.map{|v| v.to_s + ' = #{' + v.to_s + '}'}.join(",") + '"' <-- that prints out all local variables :)
<shevy>

freeayu__ has quit [Quit: 离开]

thanks, but i don't want to print them all out

eval is not debug stuff, eval should be avoid where ever is possible ... and if its not possible you wrote shit code
<workmad3>
graspee: you just need to adjust the .reject
<shevy>
if you dont like eval, you haven't used it enough

Rubinista: force_encoding just sets the internal encoding, while encode actually tries to convert the characters from the character set ruby originally thought the string was in, to the target character set. If the strings contains characters that are invalid in the old character set, that won’t really work.
mvangala has quit [Remote host closed the connection]
BiHi has quit [Quit: Computer has gone to sleep]
<burgestrand>
Rubinista: so if your string is actually UTF-8, it should be alright to force it. You could always try to set the encoding on the place you’re reading it from (for example, if using open-uri you could pass :encoding => "UTF-8" I believe)

Rubinista: unfortunately, if you try to string.force_encoding("UTF-8").encode("UTF-8") that won’t work, since .encode is a no-op if the target encoding is the current encoding. I don’t know of any good way of cleaning up a ruby string without changing it’s encoding.
robdodson has left #ruby [#ruby]
mvangala has quit [Remote host closed the connection]
<burgestrand>
It’s funny, because you can .encode from some random encoding to any target encoding and specify that invalid characters should be ignored (or replaced by some specified character), but you can’t take a string in a known encoding and replace all invalid characters.

Rubinista: that will crash if the string itself is not in a valid encoding. Say if Ruby thinks it is ISO-8859-1, while it is in fact UTF-8 and contains multibyte characters that are invalid in ISO-8859-1.

Your best option by far is knowing what encoding the string is in. All other options are likely to cause errors, crash or just give you weird characters when using the string.
<burgestrand>
Rubinista: I suppose that’s a little better :p
<burgestrand>
But when it comes to encodings you either know your encoding or you’ll inevitably cry.
rmascarenhas has joined #ruby

Yeah, I don't quite want to just set :encoding => 'UTF-8' on the HTTP connection because some of the files are executables and thus not any encoding except that they're ASCII-8BIT compatible.

Ruby likely has a strange way of parsing <<
<davidcelis>
i mean, it clearly does; calling it as a method directly on the array works. using it more as an operator fails. there is a parsing disparity

carloslopes: It feels like I'm close: https://github.com/sam/harbor-ftp/blob/continuous-testing/test/watch.rb But MiniTest is still hanging onto old tests (and class references used in those tests) somewhere. The class references are a problem since even if I remove_const and reload the original source file, the spec is hanging onto the old version of the class. So I can't make that test pass.

On the plus side I can add new tests. And running tests is instantaneous this way. If only I could figure out how to clean up the old specs. :(

digitalcakestudi if you need a var, you must keep track of it
<ssmoot>
Sou|cutter: Right, I've seen that. Haven't looked too closely though since I assumed it wouldn't help me a whole lot with MiniTest. As far as I can figure out MiniTest is the issue right now. I've got files reloading. I can add new assertions and they work fine. Methods with failing assertions appear to be cached somewhere though. :(
<shevy>
digitalcakestudi however you can do the same with counter = 0; loop { counter += 1}, or perhaps better, try something like 5.times {|i|} or 0.upto(1000).each

I'm really trying to stick with MiniTest. Other than this, I generally like it, it's simple, and because it's part of the stdlib now, I'm pretty confident it's not going to have breaking changes that will break all my specs and they'll continue to work a few years from now.
<Sou|cutter>

Hey, i've been playing around with ruby, and have run into a problem that I can't quite figure out. I have a code like this: http://pastebin.com/SAxQQnWm (Using nokogiri), and when I run that, it displays all of the names, and then displays all of the pops, rather than displaying the first name, then the first pop, then the second name and pop, etc...
chmac has quit [Ping timeout: 265 seconds]
<apeiros_>
slyv: that's because name will contain an array of all names
<apeiros_>
so if you puts it, it'll puts all values that are in the array - and all of them are names.
<Xajin>
whats the correct way to run a system command and add in some variables, like system("ls" + path) or somethin
<ssmoot>
Xajin: That's basically it. Though interpolation can look prettier: system("ls #{path || '/tmp'}")
<deryldoucette>
%x[ls #{yourvar}]
<apeiros_>
Xajin: system("ls", path)
<slyv>
@apeiros_: Ah, I see. So, how would I go about fixing that?
<deryldoucette>
then you don't need the ticks etc.
<apeiros_>
Xajin: that will not go through a subshell and eliminate the dangers of unescaped arguments

as far as I understood shell syntax, a statement is terminated by either ; or a newline…

the && in shell syntax means only execute the 2nd command if the first one succeeded
Criztian has quit [Remote host closed the connection]
<apeiros_>
yes. similar to ruby
<deryldoucette>
the ; means execute the 2nd regardless of the status of the first

which is why when i chain, i *always* use && because well if i'm running a 2nd command the 1st damned well better have worked hehe

especially since you're running a root command
<apeiros_>
[] is already the quote
<apeiros_>
adding a " inside of it makes it a single argument ;-)
<deryldoucette>
ahh crap, you're right
<deryldoucette>
my bad
<apeiros_>
Xajin: you want %x[ssh -i key.pem root@#{ipaddress} #{command}]
<Xajin>
Thanks guys
<apeiros_>
Xajin: also re "this will just be in XY where it is all totally save and fancy pantsy unicorns with rainbows!" - forget it. stuff always ends up being used elsewhere.
<apeiros_>
good security practice is a habit. better get into it asap.
<slyv>
apeiros: zip?
<apeiros_>
slyv: yes. see Array#zip docs
<deryldoucette>
apeiros_++ :-)
<apeiros_>
imagine a zipper on your trousers - one value from the left, one value from the right, left again, right again and so on
<robacarp>
apeiros_: thaht is the first time I've ever heard a good plain english description for zip.
<robacarp>
well done.

robacarp: thanks :)
<slyv>
Haha thanks, but I am getting an undefined method error when I try that.
<apeiros_>
slyv: paste the code + the full exception
<apeiros_>
exception preferably below the code
bambanx__ has quit [Ping timeout: 260 seconds]
C0deMaver1ck has quit [Remote host closed the connection]
<apeiros_>
slyv: I think you've changed the code, no?
<apeiros_>
didn't you have `reg.xpath("//NAME")` instead of `reg.xpath("//NAME").text`?

Yeah, I was testing some things. Let me try again removing those.
<apeiros_>
you might still get a no method error

since xpath probably returns something else than an array, so it depends on how well what it returns implements Enumerable (hopefully it just includes Enumerable…)

I removed them, no no method error, but it didn't change anything from what was happening originally.

And, eventually in my code, I will need .text.

But with or without, all the names come first, then pops.

slyv: remove line 9
<apeiros_>
and replace `p name.zip(name).flatten(1)` with `puts p name.zip(pop).flatten(1)`
<apeiros_>
(line 8)

apeiros_ Thank you so much, my A.D.D just would let me get past the issue of it not working. Not that I have it working, I would like to learn more of how to secure it, could you point me to some referance material link or something? Heres the output "http://screencast.com/t/Q4KrcpNRF". Now I have a way of definig an server list, running a command on each and seeing its output, in the working
<Xajin>
example I did a df -h to see the disk usage of all servers in my server list
bambanx__ has quit [Read error: Connection reset by peer]

Ah, that worked! But, now if I want to work with names and pops in my code later in that .each loop, how would I do so? (Not just puts).

slyv: that zip+flatten will return an array of the form [name1, pop1, name2, pop2, …]
<slyv>
And also just get .text, rather than the whole thing.
<apeiros_>
you can .each over that just easily
<apeiros_>
if you want a name and a pop on a single iteration, just drop the .flatten(1)
<apeiros_>
then you get an array [[name1, pop1], [name2, pop2], …]

<apeiros_>
which you can do: ary.each do |single_name, single_pop| (also, name your variables properly, should be names & pops, not name & pop. they're collections…)

aw man, almost 0200 - getting to sleep. @Xajin, look at open3, it allows for separate passing of arguments too, which avoids that exploit
