i think the source of your confusion really is just misleading output coming from L21
bluOxigen has quit [Ping timeout: 244 seconds]
<jlogsdon>
yeah
<tds>
it's not adding a make like Car.add_make does
<n_blownapart>
jlogsdon: tds: hold on one sec let me ask: the constructor depends on the add_make method to first send the make to @@makes?
<jlogsdon>
yes
<tds>
yes
<tds>
try commenting out the add_make lines
<jlogsdon>
if add_make is never called, the constructor will always raise the error
<n_blownapart>
is that why the constructor definition comes second? jlogsdon tds
<jlogsdon>
it doesnt have to come second in the definiton order
<tds>
the order of definition doesn't matter
td123 has joined #ruby
<n_blownapart>
tds: jlogsdon but I guess it is easier to read.
<jlogsdon>
correct
<tds>
yes
<jlogsdon>
class methods together, instance methods togehter
<jlogsdon>
usually instance methods are all defined after the initialize method

haha

it just takes practice, n_blownapart
<n_blownapart>
this is a beginners book. I find this prog pretty tough. If you were to look at this, where do you first start reading to follow what its doing?

tds: jlogsdon ^^
bradhe has quit [Remote host closed the connection]
<tds>
follow the order of the calls
<n_blownapart>
tds no capiche
<jlogsdon>
n_blownapart: basically what tds said. I'd ignore the Class definition all together, then go down to the calls and follow them through
<jlogsdon>
s I'd look at .add_make first. then #initialize
<jlogsdon>
and then #make_mates, and then .total_count
baphled has joined #ruby
<jlogsdon>
with that I can see that #initialize depends on .add_make being called (as @makes is defined as an empty array, so it would never include anything unless .add_make was called)
<n_blownapart>
jlogsdon: would you grant that the unless and the following constructor if statement are logically hard to read?
<jlogsdon>
and then I see the #make_mates returns some information handled in the constructor
<jlogsdon>
and then .total_count does the same
wallerdev has quit [Quit: wallerdev]
<jlogsdon>
I would grant that the logical statements can be confusing until you grok the diffreence between @@var and @var. Outside of that, the logic should not be difficult.

.add_make: unless @@makes has this thing, add this thing to @@makes. also setup @@cars[make] with an integer
gavit has joined #ruby
<n_blownapart>
jlogsdon: thanks got that.
<jlogsdon>
#initialize: if @@makes has this thing, print a line, set the @make, add a value to @@cars[make] and @@total_count. if the first condition is NOT true, raise an exceptional condition
<jlogsdon>
and then the other two just read information

I think one thing that may through people off is unless versus if. If is *super* common in programming, but unless is a "wtf" the first few times you se e it

jlogsdon_: thanks. I was studying that prog. and now I cannot see where the key => value values are created for @@cars = {} in line 3. Don't those parameters need to be explicit?

in .add_make
<jlogsdon>
L15, @@cars[make] = 0 sets the key => value

you'd need a pretty big investment in the beginning to bring in domain experts like doctors and medical researchers and shit
<banister`sleep>
Ivis: but put it this way: you don't have programming skills, you dont have medical expertise, you dont have the money for investment. All you appear to have is an idea that's not even that original, i.e it exists for other languages, just not latvian
<Ivis>
cuz drug stores always put ads everywhere and imagine if this website will provride information what pills you must use

theres no definitive 'best' for this type of app from those 4?
savage- has joined #ruby
pu22l3r has quit [Remote host closed the connection]
<glistle>
arooni-mobile: ruby is a vast ecosystem, sinatra is a web framework so the glue around, you may use rails or ruby scripts instead. nokogiri is for the scraping. httparty or mechanize for doing gets/posts. mechanize makes it easy to work with existing webpages (clicking, posting forms) httparty for apis or form submissions.
<arooni-mobile>
ok thats a good overview thank you
<glistle>
arooni-mobile: nokogiri is the parsing part, mechanize will pull/scrape the content off the site to be parsed easily by nokogiri.
<arooni-mobile>
so sounds like i need the part that does GET/POST (httparty or mechanize) ... and the parsing (Hpricot/Nokogiri)
<arooni-mobile>
sounds like nokogiri is the clear winnre for the second half
<arooni-mobile>
so i guess thing is to decide between httpparty and mechanize

banister`sleep has quit [Read error: Connection reset by peer]
<bluebie>
when you write "class Something" it begins a section of code which needs to be finished with a matching 'end' before it's done
<bluebie>
if you create a class inside of that class, you'll end up with something like Class::Hybrid
<bluebie>
er sorry
<bluebie>
Car::Hybrid
<bluebie>
instead of just Hybrid

This is called namespacing, where a class can have it's own internal set of constants - which can be anything = a class, a number, whatever. Math for example has Math::PI which is a float. If you just write PI though, you get an uninitialized constant error
igotnolegs has joined #ruby

give it a go and you'll see Car::Hybrid works :)
hemanth has joined #ruby
<n_blownapart>
bluebie: I only have Ruby as a context...first language. I was putting Car::Hybrid on lines 51,52, and 60 and it would work while Hybrib < Car was at the top. I took out Car:: and then it wouldn't work while that line was at top. sorry I don't understand.
<bluebie>
You can explicitly say to ruby 'don't namespace this - put it in the root namespace' by adding :: before your class name. class Car; class ::Hybrid < Car; end; end for instance creates both Car and Hybrid as global constants so you don't need the Car:: prefix when talking about Hybrid - but that's a weird and confusing way to code - it's clearer to avoid such strange nesting
<bluebie>
right, so Car is not only a class, it's an object too!
<bluebie>
just about everything is an object, even classes!
RichieEvan has quit [Quit: RichieEvan]
<bluebie>
and inside the Car object, it has things like instance variables, some methods, and it also has some constants
<bluebie>
by being inside the 'class Something … end' section of your program, you establish a context of which class you are in, so syntax like def, @vars, @@vars, and Constant = <something> all happen within that class object, instead of the main object (the global default one)
<bluebie>
they're nested, a bit like folders within folders in a computer
<n_blownapart>
bluebie: thanks. the point of the lesson was to add an instance variable so that the subClass could count on its own. But sorry, I don't follow the part you wrote about the finishing with an end.
<n_blownapart>
bluebie: hold on, digesting that...
<bluebie>
the :: operator is how you say 'get the constant to the right which is inside the thing on the left'

ok bluebie one sec. What I don't see is that if Hybrid is inheriting from Car, why the entire prog. doesn't pertain to Hybrid. why should it matter where Hybrid < Car is placed?
techsurvivor has joined #ruby
<bluebie>
it doesn't matter where it's placed, so long as something called Car exists, and that thing is something you can inherit from (a class object)
<bluebie>
if you put it before 'class Car' then it cannot, as nothing called Car exists yet when you run it
gavit has quit [Read error: Connection timed out]

t51663 has quit [Remote host closed the connection]
<bluebie>
if you put it inside of 'class Car', it does work, but it is created inside of the Car class, instead of the program's main outter section, so you need to write Car::Hybrid instead of just Hybrid to access it from things which aren't also inside of Car

I've not yet fully baked my ideas for the GUI and user friendly programming interfaces and all that stuff
<burgestrand>
bluebie: however given some instructions I can probably work my way around that as well if necessary
<burgestrand>
bluebie: but I’d guess you’re aiming (when done) to get it out to a less technical crowd?
<burgestrand>
i.e. probably not have them upload code to the microprocessor unless they really want to? :p
<bluebie>
I rather like the thought of using light or sound to transmit the program in to the device because iphones and other devices with weird or no ports can do it, they're easy to send around through the internet (animated gifs or wavs) and it's clear to even a total noob how it works, so they can intuitively fix a lot of problems - where something like a usb dongle is pretty opaque and magic
<bluebie>
I'd release source code
<bluebie>
yes, the nontechies are my main aim
<burgestrand>
yeah, that idea of just… showing the device some light sounded awesome
<n_blownapart>
bluebie: burgestrand did someone say nontechie?
<bluebie>
still the firmware would be open source for noncommercial uses at minimum, and if I do end up using a turing machine model, I'd release some sort of assembler too

<n_blownapart>
burgestrand: interesting. by the way I'm a geezer. I'm 50 this shit is hard. you mean load / require at bottom? bluebie burgestrand?
<bluebie>
burgestrand: I could have it just implement fixed functions - so for each 'program slot' you'd upload which function to use, and some data for it - settings, lists of colours, that sort of thing
Guest85391 has quit [Quit: Leaving]

so you'd be able to reconfigure and tweak animations already implemented, but not add entirely new things

it reads in it's own source code and gsubs constant names to be other ones then evals itself them in some functions

you can break the key finder in to another line with a good variable name like 'first_key_found' if you like for bonus clarity points

I guess because it's an annoying function definition and shouldn't exist anyway

are you cheating? is it much faster to write than statically typed languages that don;t need type annotations?
lkba has joined #ruby

eh, I don't know about that
<hoelzro>

<JonnieCache>
strongly typed languages without type inference obviously suck
<JonnieCache>
but honestly who uses them? apart from corporate types

ex. I wouldn't use a static language for a scripting language
<hoelzro>

"would anyone here like to show me why dynamic typing is superior to a static typing (and you have to use a good example of static typing like ML or haskell or scala, not C++ that's cheating)?" was my original quote chevy
<JonnieCache>
ah good point. not quite the same thing though because you dont have classes as such
<JonnieCache>
less cognitive load
<shevy>
lewis1711 no instance of cheating
<lewis1711>
I should've said "not stuff like C++"
<hoelzro>
JonnieCache: you mean classes increase or decrease cognitive load?
<shevy>
"good example" eh
crl_ has joined #ruby

your question is basically "why is haskell better than ruby"
<lewis1711>
it's easy to show me some algol static typing mess and say dynamic is superior, but modern static systems are not like that
<lewis1711>
no
<shevy>
#haskell also has more people than #ruby
<JonnieCache>

you're the guy that got hyper, hyper defensive about this before

defensive about what?
<JonnieCache>
lewis1711: sounds about right
<shevy>
ruby has only one advantage compared to haskell
<shevy>
it is easier to learn
<lewis1711>
I asked why ruby couldn't catch incorrectly named methods being called, before they were being called, and you went ballistic
<JonnieCache>
lol
rburton- has joined #ruby

I have no idea what you refer about
<lewis1711>
oh
<shevy>
well, haskell *is* popular
crl_ has quit [Client Quit]
<lewis1711>
no I just keep trying to find a reason to love dynamic typing
<burgestrand>
haskell has the appearance of being popular, I wouldn’t go as far as to say it is
<shevy>
and when many people like something, then that thing must have something going for itself
<lewis1711>
this isn't about haskell. it;s about the strawman of comparing DT with the ST of languages with poor ST systems
<shevy>
even PHP
<lewis1711>
which I see too much
<hoelzro>
lewis1711: why do you feel a need to find a reason to love dynamic typing?
<shevy>
lectrick, but you said it is a good language / good example
<JonnieCache>
lewis1711: its just the difference between sketching with charcoal and applying paint to the canvas. its a stylistic thing. you'll never find a hard and fast technical justification for it
<burgestrand>
the choice is dynamic
<lewis1711>
hoelzro: because there are so many wonderful dynamically typed languages
<burgestrand>
:d
arkiver has joined #ruby
<shevy>
and we should compare real languages to one another, so haskell on the one side... and [some other language here]
<lewis1711>
and by many, I mean.... two or 3
<shevy>
ok but let's get specific and compare two languages
<lewis1711>
alright
<lewis1711>
ruby and scala
freeayu__ has quit [Read error: Connection reset by peer]
<shevy>
hmm
<lewis1711>
both very OO
<lewis1711>
everythings an object
<lewis1711>
one very static, the other very dynamic
<hoelzro>
lewis1711: well, in my experience, dynamic langauges tend to be more flexible, more inspectable at runtime, they allow metaprogramming, and they typically have a quicker development cycle
<hoelzro>
emphasis on 'tend' and 'typically'
<lewis1711>
hoelzro: inspectable at run time?
<JonnieCache>
scala's type system is so crazy though that you can have quite dynamic behaviour
<JonnieCache>
i cant remember the specifics, it was probably just hacker news gossip tbh. i think it was to do with them lacking direction for the next version.
<JonnieCache>
oracle's influence may have been involved as well
whowantstolivefo has joined #ruby
<hoelzro>
lewis1711: well, I can't really speak to that, because ina static language, you can have the compiler verify that you're not calling certain methods, etc
<lewis1711>
that is also true
<JonnieCache>
maybe it was to do with them running up agaainst the limited of the jvm's capacity for dynamic dispatch. even with the new invokeDynamic bytecode there is a limitation to how fast it can be
<lewis1711>
I like the idea of testing behaviour with unit testing, rather than types with static types (of course it's not one or the other
<hoelzro>
some Smalltalk implementations' approaches are interesting
zz_chrismcg is now known as chrismcg
<hoelzro>
lewis1711: most DT languages have a fairly pervasive testing culture
<hoelzro>
ex. Perl, Ruby
<hoelzro>
so once you refactor, run your test suite
<hoelzro>
and if it passes, you're good =)
<JonnieCache>
lewis1711: yep. if you have 100% coverage on your tests you basically have most of the benefits of static typing
<JonnieCache>
wrt to catching errors

hi, i've got a string where i need to match a complex regexp via str.scan(/regexp/). now i want to see which parts of the string did not match (so that i can raise an error if something is unmatched that isn't whitespace) how do i best accomplish that? any ideas?
pandalike has joined #ruby
workmad3 has joined #ruby
<apeiros_>
msch: use a block and $` (or $' - I always confuse these)
<msch>
apeiros_: ah of course! global variables to the rescue!
<mklappstuhl>
i have a csv file that starts with a BOM which causes CSV.foreach to break with "illegal quoting"
<apeiros_>
mklappstuhl: did you state the encoding?
<apeiros_>
(since BOM is only utf-16 and higher)
<mklappstuhl>
apeiros_, no I did not. I want to parse multiple files with the same code and I cannot guarantee that they are all utf-16
Shrink has joined #ruby
<msch>
apeiros_: hm, but now i have pre/post_match, what do i do with it? i mean i get the same pre/post_match strings no matter if the regexp matched those before or not
<apeiros_>
mklappstuhl: an application *can not* determine the encoding on its own
<mklappstuhl>
apeiros_, so I''m kind of looking for a "robust" way of handling that
<apeiros_>
you *must* supply the encoding
<apeiros_>
there is none.
<apeiros_>
anything but explicitly providing the encoding is gambling
<Mon_Ouie>
If you don't provide the encoding, all you can do is try guessing — which sure isn't robust
<mklappstuhl>
apeiros_, and where do I get the encoding fromß
<apeiros_>
you can do a bit of heuristics, but nothing absolute.
<apeiros_>
mklappstuhl: either you know it, you require it or you need additional user input
<mklappstuhl>
well okay that sounds bad
<apeiros_>
re heuristics: you can check for the BOM and when present assume utf-16. you can check for valid_encoding? with utf-8 and assume utf-8 if it is valid, you can then go on to check character frequency
<apeiros_>
reminds me that I wanted to write a byte frequency implementation in C
rburton- has quit [Quit: rburton-]
<mklappstuhl>
apeiros_, Isn't BOM there to tell which encoding is used?
<apeiros_>
mklappstuhl: no
<apeiros_>
BOM is Byte Order Mark
dpk has joined #ruby
<apeiros_>
it tells you the byte order
<apeiros_>
and you need to know that what you see is indeed a BOM
<apeiros_>
because it's first and foremost just 2 bytes
<workmad3>
mklappstuhl: also, if the CSV foreach is breaking with 'illegal quoting'... that's probably a malformed CSV file, not a bad encoding...
<apeiros_>
but since those 2 bytes will rarely every be at the beginning of a file, you can infer from it that it is likely utf-16 or higher
<apeiros_>
workmad3: well, if it reads it as single-byte encoding…
<apeiros_>
all those null-bytes can certainly cause odd parsing exceptions
<workmad3>
apeiros_: true, it could cause odd parsing exceptions... but I'd probably start by checking if it's a malformed CSV file myself :)
<apeiros_>
sure
<apeiros_>
got to follow all leads :)
<mklappstuhl>
workmad3, did that before asking here of course. I was also able to "confirm" the BOM thing by opening the file in vim doing :set nobomb :wq and retrying
<apeiros_>
nobomb, lol :)
<apeiros_>
they set us up the bomb!
<apeiros_>
aaaah, these were the days…
fermion_ has joined #ruby
<mklappstuhl>
so. how does vim know that there is a bom char? I cannot really imagine that this really requires additional input -.-
<hoelzro>
mklappstuhl: the BOM is special
<apeiros_>
hoelzro: not really.
<apeiros_>
it's just unlikely to be something else.
<apeiros_>
i.e. - educated guess.
<hoelzro>
and Vim assumes that if it sees a combination of two bytes that make up the BOM, it is encoded that way
<apeiros_>
see heuristics in scrollback
<hoelzro>
apeiros_: fair enough

t47671 has joined #ruby

it's fun how often people run against this issue
mike4_ has joined #ruby
<apeiros_>
and it's sad that there still is no file container which would store the encoding
<hoelzro>
but as hard as it is, it's a really fascinating problem!
<workmad3>
probably the most relevent quote from that is: 'If you have a string, in memory, in a file, or in an email message, you have to know what encoding it is in or you cannot interpret it or display it to users correctly.'
<apeiros_>
the only PITA is that we have no, or only limited, ways of transporting the metadata
<apeiros_>
the moment you save a file the information is gone.
<workmad3>
apeiros_: well, the real PITA is that the metadata itself needs to be stored in some encoding...
<apeiros_>
the moment you *have* the information, anything else is dead trivial
<workmad3>
apeiros_: and then you just move the problem from how to work out the encoding of the data to how to work out the encoding of the metadata :)
<apeiros_>
workmad3: not an issue. that's about protocol.
wobr1 has joined #ruby
<workmad3>
apeiros_: that assumes you have a single prototcol
<workmad3>
*protocol
<apeiros_>
yes. and that IS an issue
<apeiros_>
(and I said so before - no unified file container)
<workmad3>
apeiros_: the encoding issue itself could be sorted out if we had only a single encoding...
<hoelzro>
apeiros_: well, perhaps I misspoke

I should say that Unicode is complicated
<apeiros_>
workmad3: that will likely not happen in our lifetime :)
<workmad3>
hoelzro: it's not particularly complicated
<hoelzro>
Unicode is the iceberg of which I speak
<apeiros_>
hoelzro: unless you have to implement low level things - no
<hoelzro>
I think case folding and collation and all that stuff is pretty complex!
<workmad3>
hoelzro: it's just that people don't bother learning even the bare minimum and then start getting things wrong :)
<apeiros_>
if you have to do low-level things, like implement a regex library, or a case-changing function - yes
<apeiros_>
but even then, unicode provides you means you didn't even have before.
<hoelzro>
apeiros_: right, I'm talking about the general problem
<hoelzro>
like the work that the commitee and implementors have to do to make sure they get it right
<workmad3>
hoelzro: once people stop assuming that string data has some implicit meaning that doesn't require an encoding...
<apeiros_>
yes, but that's 0.00001% of all developers who have to be concerned
<apeiros_>
*you* and *I* don't have to care about that. we get the libs based on their work
<workmad3>
hoelzro: or even that *any* data has an implicit meaning and doesn't require an encoding...
<hoelzro>
apeiros_: right
<hoelzro>
I guess I'm trying to say that I appreciate the difficulty imposed on others, not myself
<hoelzro>
workmad3: agreed
<mklappstuhl>
I'm porting this csv stuff from php. and we did not handle any encoding there at all
<workmad3>
mklappstuhl: so it only worked by fluke is what you're saying
<mklappstuhl>
workmad3, yeah kind of

you probably want to add '-E', 'utf-8:utf-8' to your spawn

alternatively: '-E', 'binary:binary'

the latter is probably "safer"

JonnieCache: It's a heavy customized proxy, so WEBRick is a good choice I think
<enroxorz-work>
because within left_row[key] and right[row] key are a ton of other cells i need to compare
<apeiros_>
enroxorz-work: use a hash, assuming eql? is good enough for you (instead of ==)

JonnieCache: why?
gavit has joined #ruby

JonnieCache: It saves a lot of time because I do not have to write a proxy on my own

<workmad3>
foofoobar: why not just use apache?
<foofoobar>
workmad3: no
<workmad3>
foofoobar: or nginx?
<enroxorz-work>
so the original problem is I have two excel sheets. Rows from left have to be in right, and data must match. All data on both is seriously screwed up with spacing and formatting, so I had to improvise just so I can compare. They want all differing data points through out the whole wooksheet
<foofoobar>
the "proxy" modifies the request/response
<foofoobar>
so it's not a normal proxy
<workmad3>
foofoobar: that depends on how it modifies the request/response
<lectrick>
How do I make a class monkeypatch that only works within blocks passed to a special method?
<workmad3>
foofoobar: reverse proxies modify the request and response in limited ways after all ;)
<workmad3>
foofoobar: sounds more like a filter than a proxy though...
<foofoobar>
Yeah, kind of
<foofoobar>
I think I'm fine with WEBRick. I'm not looking for a different solution the webrick. I'm looking for a way how to run a WEBRick-proxy and a sinatra app parallel
<workmad3>
foofoobar: still... webrick is a very poor ruby app server
<foofoobar>
They should interact in some way
<foofoobar>
workmad3: but it fits my needs, so why looking for something different?
<foofoobar>
it has to handle just a very little amount of request, it's okay I think

using a wider variety makes no difference

rewrite vs. start-from-zero-anew
<workmad3>
shevy: isn't that because those are the same thing?
<shevy>
not completely! right now I rewrite my oldest and largest ruby project, I started from zero, but I also want to retain most of the old features... but I can't copy / paste 1:1

<shevy>
it all feels a bit silly to rewrite
<shevy>
it used to work in the past... just was not very clean and such
<shevy>
I'd rather like to come to a point where I would never have to rewrite anything at all again
<workmad3>
shevy: yeah, the rewrite argument goes 'if we start from scratch, we can do a better job with the design, we know more, we can do it all better now'

shevy: while the refactoring to more maintainable code says that the big rewrite argument is bs and you shouldn't throw the entire thing away, you should gradually refactor it to turn it into a more reasonable code base

shevy: bearing in mind that a complete rewrite does mean you need to invest resources into just getting it back to the current level of implementation, but it might still be more cost-effective to do that as opposed to refactoring if the code base is *really* bad

goyox86 has quit [Remote host closed the connection]
<shevy>
four directories in that latter directory. core/ addons/ dependencies/ and yaml/
<shevy>
and most .rb files reside right at the base of lib/name_of_project/
<shevy>
hmm 34 .rb files in that base dir right now
<workmad3>
right, so that file organisation says to me 'I have no real structure, I'm probably filled with quite tightly coupled subsystems'
<shevy>
yeah
<workmad3>
whether that's true or not... that's what the file structure says :)
