I am having a hard time debugging an exception that doesn't get rescued, maybe someone has some insight
keanehsiao has joined #ruby

I am actually catching it inside a rescue block and then raising it again
<David_Mi1ler>
rescue Exception => ex
<prezjordan_>
seanstickle: thanks for your help
<David_Mi1ler>
raise ex
<David_Mi1ler>
does nothing
<David_Mi1ler>
but if I put raise "some text"
<David_Mi1ler>
I can catch that one fine
xclite has quit [Quit: Leaving]

why would i get an undefined method for grep? start.rb:57:in `block (2 levels) in <main>': undefined method `grep' for #<Strin
oktapodi has joined #ruby
<bnagy>
because there's no grep method for String?
<offby1>
because strings don't have a method by that name?
<offby1>
curse bnagy and his fast fingers
<bnagy>
it's an amazingly logical language sometimes :)
<xclite>
when all else fails, the error tells you exactly what's wrong
<zeknox>
i dont get it, it was just working
<bnagy>
zeknox: not unless you were in a parallel universe or you were operating on an Array before
<offby1>
zeknox: split it up into smaller bits, write unit tests for 'em
<banisterfiend>
offby1: btw just typing: ls "" works too
noodletraveler has joined #ruby
<offby1>
banisterfiend: ooh
<banisterfiend>
offby1: if u pass a parameter to ls it'll just operate on that parameter without u having to change scope
<offby1>
banisterfiend: so, is there a M-x pry command for emacs? I'm half-serious
<bnagy>
I don't know exactly what logic you want but something like if up=~/Up/ # get the ip end
<banisterfiend>
offby1: i try to be as analogous to the normal system shell as possible
L-----D has quit [Ping timeout: 250 seconds]
<bnagy>
zeknox: your second grep (after split) should work
<banisterfiend>
offby1: nah, though somsone was working on emacs integration at some point, but my energies are usually exerted into bringing cool functionality in a cross-editor way rather than sticking to emacs, unfortunately emacs use isn't that prevalent in ruby
<xclite>
zeknox: just checked in irb and strings will let you grep, though I'm not getting any errors when grepping on strings or arrays (the things that should be recipients of the grep message in your pastie)
<bnagy>
or while (line=file.gets); next unless line=~/Up/; more stuff

Mohan has quit [Ping timeout: 248 seconds]
<bnagy>
xclite: no idea what you typed, but String does not have grep.

David_Mi1ler: do you do "#{"hello"}" too?

bnagy: there we go - 1.8.7 has grep and 1.9.1 does not

niklasb has quit [Read error: Operation timed out]
<bnagy>
David_Mi1ler: inspect it! look at ex.class! Enquiring minds and all that...
<apeiros_>
raise without args reraises the last exception
<David_Mi1ler>
yeah I inspected it and its a regular Exception
<David_Mi1ler>
afaict
jayrulez has quit [Read error: Operation timed out]
<bnagy>
what class?
<apeiros_>
but if you did (as I read in the backlog) rescue Exception => ex; raise ex; end - then that should work the same as a plain raise without args.
altiouz has joined #ruby
<bnagy>
like Exception instead of StandardException is not same same
<bnagy>
sounds like a busted lib, based on limited information - you should never have to rescue Exception
<David_Mi1ler>
well it is part of some hairy retry logic that I inherited
<David_Mi1ler>
#<Exception: Error occurred while ..... is what I get from ex.inspect
h4mz1d has joined #ruby
<bnagy>
zeknox: using to_s on an Array when you probably mean join is a bad habit, and I would call the line 'line' not 'up' cause you don't know if it's up yet
<David_Mi1ler>
and I get Exception from ex.class.name

<bnagy>
David_Mi1ler: they should have just raised RuntimeError or subclassed like NotFoundError < StandardException

banister_ has joined #ruby
banisterfiend has quit [Read error: Connection reset by peer]
<bnagy>
annoyingly, you have to actually really try to raise Exception - like it defaults to RuntimeError

well the exception actually comes from net/http, we handle it in the very last rescue section after we have checked for more specific ones

if you are on 1.9.x you may have to use require './myfile.rb'

or require_relative 'myfile.rb'

or, bundle it into a project, then install that project, then you can do require 'myfile.rb'

and another option is to modify load path... I think this is the variable %:

thanks shevy =)
<shevy>
it works?
TheIronWolf has joined #ruby
<bambanx>
yeah
<shevy>
ok good
<bambanx>
requiere './myfile.rb'
<shevy>
if it works, you can think of all required files as "one huge .rb file"
<bambanx>
require*
<shevy>
as if you would have pasted everything into one .rb file
wilmoore has quit [Remote host closed the connection]
<shevy>
now you can use all modules and classes from those files
<bambanx>
o nice
<bambanx>
is like a pattern?
<shevy>
most ruby people will eventually write one parent module, and put everything into that module, when they have many different .rb files
<bambanx>
this is when some people talk about patterns?
Haydos has quit [Quit: Leaving]
<shevy>
bambanx, more like the way how you work in ruby
mikepack has joined #ruby
<shevy>
for instance, let's say you have a project called "foo"
<shevy>
typically you would create a module called
<shevy>
module Foo
<shevy>
and inside that module, you will put all your classes
<shevy>
module Foo
<shevy>
class Bar
<shevy>
class Ble
<shevy>
end
<bambanx>
ok
<shevy>
and often, people will write class Bar in file bar.rb and class Ble in file ble.rb
<shevy>
you see?
<bambanx>
yeah
<shevy>
bambanx, it is more a convention
<shevy>
it can make life easier, because you know what goes where by the name alone
<bambanx>
is more order i think
<shevy>
yeah
<bambanx>
more nice programming
<shevy>
not everyone uses that convention, but I like it

Maybe Ruby was designed from the start with it in mind, but I'm sure other languages have this problem.

maybe ones from the 80s

if you do nothing but refcounting you would have it, yeah, but things move on
<rippa>
Another solution is to periodically use a tracing garbage collector to reclaim cycles. Since cycles typically constitute a relatively small amount of reclaimed space, the collection cycles can be spaced much farther apart than with an ordinary tracing garbage collector.

in ruby cyclical garbage is collected too, but if something isn't garbage it isn't collected

that means, if you keep a freference somewhere, the object wn't be colected

<banister_>
instead i would just regenerate the branch-with-secrets-removed fresh each time u wanted to push
<banister_>
by rerunning your filter-branch script on master
<bnagy>
hm... ok yeah that's doable
<banister_>
but it would be kind of useless
<bnagy>
but if I'm going to do that I may as well use rsync with a manifest
<bnagy>
which is my leading option

I'm not sure how to read a file with today's date. How do I be _clear_ about that unknown number?

jankly_ has quit [Read error: Connection reset by peer]

the crux is that tests are using stringio to create mboxes that sup will parse, but sup assumes the mbox file to be a file (right?) and not stringio...

avtobiff: File.size(@f) returns the size of the file named by @f. @f.size returns the size of the filename itself.
<avtobiff>
Alantas, aha. so what do i do if @f is stringio?

if I reference a method within a method, do I have access to the referenced method's variables?

wanna DRY up some code if possible
<fowl>
no you only have what the method returns
<becom33_>
shevy, bnagy kissed me while ago
<bnagy>
jeebster: the only sensible way to get access to a methods vars is to get them on return
<David_Mi1ler>
ok so these exceptions should probably be StandardErrors

ok, so I should return the variables

a_a_g has quit [Quit: Leaving.]
eka has quit [Ping timeout: 246 seconds]
<shevy>
as a whole, I think the biggest difference is the OOP model and how one tends to "think" when solving a problem in ruby, as opposed to "think" when solving the same problem in python
<shevy>
in python one has to carry explicit self into methods
<shevy>
def foo(self)
<luyang>
oic
<luyang>
that is an interesting differenc
<shevy>
i.e. python objects are not very clever, as they dont know themselves :D
<luyang>
e
<shevy>
then, in ruby it is more natural to do
<luyang>
shevy: LOL! good point
<shevy>
foo.each
<shevy>
collection.each
<shevy>
in python they tend to prefer to use [] conditions... dunno like ... [for x in y blabla]
<shevy>
it's hard to describe, but it's a different way to think
<luyang>
I see
<luyang>

then there is something that ruby took from perl, which is that one tends to be creative, innovative and agile when a problem comes. "there is more than one way to approach something". this can be confusing sometimes for people, python prefers to consolidate on one way that works
<luyang>
so I dunno if Ruby or Python would be best for me to learn and if I can use them easier than just using java
<shevy>
both are good choices
<luyang>
shevy: I see…
<shevy>
I switched from PHP to ruby
<shevy>
back then, I considered both languages
<luyang>
interesting… I just wonder if I can write things to solve everyday tasks in ruby
<shevy>
the deciding factor for me was a matz interview :)
<luyang>
I guess what I want is to find examples of how to solve things in ruby, not just learn the syntax
<shevy>
perhaps guido has too, but back then I could not find such an interview
<shevy>
luyang well, it depends on the problem you want to solve
<shevy>
it can always be hard brain work :\
<shevy>
I try to avoid that by coding in a way as to never have to think about anything
<shevy>
I write only dumb code
<luyang>
I wanna do things like create all my sub folders to git repositories, find files that contain certain text, fetch web pages from the internet that meet criteria , etc

the fileutils module to create subfolders
<luyang>
that sounds very powerful!
<shevy>
URI open() to fetch web pages
<shevy>
luyang, I think you can do the same in python. keep an open mind about both languages :)
<Synthead>
nobody knows? :s
<shevy>
for me, I could have perhaps been using python. but now I am very used to ruby, it's hard to switch. Plus, with the current transition to python 3 and the mess, I really dont wanna learn it right now

I've been hacking at this for hours :/

hi... i'm using rvm, i installed thin, and it tells me i need the rails 2.3.5 gem - but that shows up in my gem list, so what gives?
<Synthead>
shevy: I don't understand. cp() doesn't do any copy operations from what you've described
<shevy>
or do some checks. if ! File.exist?(input)
<shevy>
Synthead, oh, you still have to use FileUtils of course
<Synthead>
shevy: oh, I see.
<shevy>
I dont know of any other way for ruby itself to copy or move something other than FileUtils
<shevy>
Synthead you could try to use FileUtils directly, but in my experience it raises errors in certain situations, which can be annoying
