I'm having a slight issue with my Ruby. Whenever I try to run a Ruby file from the command prompt, it wants me to open it in an external program.

TheMysticWyvern: what are you entering exactly? What OS?
<shevy>
sounds like windows
<TheMysticWyvern>
jtdoncas: I'm doing "cd C:\Ruby" which is where my .rb files are saved to. Then, I type in "methods.rb," and it opens up the prompt to select an external program. I'm using Windows 10 64-bit.
<zenspider>
why is it always windows?
<TheMysticWyvern>
Back when I first installed Ruby, I don't recall it ever doing this.
<jtdoncas>
ehhhhhh, windows :(
<TheMysticWyvern>
But, I took a months' hiatus from it, and now it's all weird.

and you setting it *always* to binary has a rather bad side effect - it'll remove *everything* which is beyond ascii:
KnowledgeOwl has quit [Remote host closed the connection]

that's because only 0x00-0x7f in ascii-8bit are mapped to characters. all other bytes are just that - bytes. so it can't be translated to utf-8.

norc: as said, encode maps characters. say "A" is 0x30 in the source encoding and 0x41 in the target encoding, then that means encode from source to target translates 0x30 to 0x41. and "A" will remain "A". same character, different bytes to represent it.
ferhaty has quit []
<apeiros>
norc: but in binary, e.g. 0xC3 is not mapped to a character. if it's not mapped to a character, you can't translate the bytes to keep the character the same (because, as said, there is no character)
KnowledgeOwl has quit [Remote host closed the connection]
<apeiros>
so ruby does the sensible thing and raises. it tells you that there's bytes in the string it can't translate.
<norc>
apeiros: By which mapping fails Ruby to recognize the related character? Is it assuming a binary encoding of ascii?
KnowledgeOwl has joined #ruby
<apeiros>
norc: it assumes nothing. you tell it the source encoding. String#encoding is the value it uses for the source (or the second arg passed to .encode)
dumdedum has joined #ruby
<apeiros>
and ruby does not fail to recognize the character. the encoding *does not specify* a related character.
<norc>
"But as the name insists, its characters in the range of ASCII are considered as ASCII characters"
<apeiros>
ascii-8bit does *not have* characters in the 0x80-0xff range
<norc>
Its all falling together now.
<apeiros>
yes, the range of ascii characters is 0x00-0x7f
<apeiros>
and those it can translate.
<apeiros>
(from ascii to utf-8 even trivially - the bytes are the same there)
<norc>
apeiros: Ah. Im guessing that is why utf-8 is called "downwards compatible" to ASCII?
terlar has joined #ruby
<norc>
Because the bytes for the codepoints are the same for the characters defined by ASCII
KnowledgeOwl has quit [Remote host closed the connection]
KnowledgeOwl has joined #ruby
<norc>
apeiros: So I understand why my force_encode solves this problem. Guess I have to figure out why some library down the stack changes the encoding to ASCII-8BIT when a non-ascii character is encountered - and more to the point why that only happens when Rails calls it.
arup_r has quit [Remote host closed the connection]

Igor2__: and with 2.0, 2.1 and 2.2. 1.9 is EOL, 2.0 will be soon enough, port it to 2.2 ;)
<Igor2__>
the code wants to use rb_define_global_function to register multiple global functions to a single C function

and there is a dispatcher in the C function that figures out the actual function name used in ruby

I guess if everything else fails you could write some macro that binds them to individual functions that call your dispatcher with the name as argument

the C project is not OOP, and honestly, I'd like to go for the simplest approach possible

it's a multi-language project that tries to provide a common intrface independent of the scripting lagnuage so instead of trying to do the most advanced stuff in each language it goes for a common minimum

this is the signature is `VALUE rb_eval_string(const char *str);` so it evaluates a NULL-terminated C string. So, if your script is a string, that should do it

i guess i could run the main part by the eval() trick, but i guess the script context wouldn't persist

what is the difference between calling an instance var with `@var` and `self.var`?
<Igor2__>
so i couldn't make further calls into it
<[spoiler]>
youch: self.var uses public access
<jhass>
youch: first accesses the var directly, self.var is a method call
<polpak>
youch: self.var calls a method
<[spoiler]>
and is actually a method; so if you didn't define attr_accessor or attr_reader, it won't work

it's different because i have to check if it's blank or not

Takes about 45 min to import. Is there something I am missing? Or is this more rails specific?

yah I don't understand it, but surprisingly, the head professor of bioinformatics at one university here, uses drupal for internal management of all projects - and he doesn't even know php...; he also uses tcl, strangely enough

This works just fine though I've found that when the array is size 1 I don't get true/false, I get the value of the first element. Can

i think the reason its concerning to me is if you think of inject as reduce, and you expect to run an operation over a bunch of values. its surprising to see the block not execute. what if i had an array of strings and wanted to do a word count across all of them. if i only had one string in the array i would get that string, not a word count

now that I can explain what happened here, I'll let it go :)

yep point taken, i really just wanted to understand why the block wasnt executing and now i do, if you use the first/only value for the memo, theres nothing else to pass in

So, this may be a uselessly general question but here it goes: I want to get "better" at ruby, but am not all that creative. This makes it hard to think of programs I want to write. A book I'm reading suggests reading the code in the standard library as a way to get better at reading and writing ruby. This seems like a good idea to me but I'm at something of a loss of where to start looking (in terms of classes/files, not "Where'

haha endless possibilities are kinda the issue I'm having. Though I do like the idea of some kinda of text based DnD kinda thingy. And I'll be sure to give string and enumerable a read. God knows I need to understand enumerable much better

newbie question but what is the difference in a gem when 1) is net-ldap and 2) is net/ldap
<ruby-lang321>
are they the same?

hmm is it an acceptable practice to subclass from StringIO? I need a logger-object that can temporarily grab all output going to stdout, but also lateron restore to default ruby behaviour again

in examples when i query for ldap in ruby i see there are 2 different require statements
<ruby-lang321>
one is require 'net-ldap' and the other is require 'net/ldap'
<BraddPitt>
the "/" means ldap is a sub-directory of the "net" directory
<BraddPitt>
wherea net-ldap is all one directory
<BraddPitt>
does that make sense?
<ruby-lang321>
i see
baweaver_ has joined #ruby
<ruby-lang321>
so if i do require 'net-ldap' i get the parent and all subdirectories?
nicechap has joined #ruby

and if i do require 'net/ldap' i get everything under the net/ldap directory
rcvalle has quit [Quit: rcvalle]
<BraddPitt>
yes
<BraddPitt>
well
<BraddPitt>
require 'net-ldap' will only require what is in that parent dir
tmtwd has quit [Quit: Leaving]
<BraddPitt>
but its possible that in that dir, there is a require statement that pulls in all the sub-dirs
<BraddPitt>
(this is a common idion in gems)

hey folks. can someone help me out? I can't quite work out how to phrase what I'm after, so my google-fu is returning nothing too helpful. What I'm trying to work out is this: How do I access an attr of a class, using a variable. Eg: attrs = [ 'name', 'age' ], and I want to loop through and pull the values for person.name and person.age? (My actual array has about 12 elements, and it's all done within another loop)

<BraddPitt>
senoralastair do you mean retrieve all variables of an object?
<BraddPitt>
or rather, all the values of all the variables of an object?
<senoralastair>
BraddPitt: In this instance I'm just after the values they hold, but it would be good to know both for future use
<Aeyrix>
Is here an appropriate place for Sinatra questions?
<Aeyrix>
It's not directly Sinatra related, but I'm using the framework.
<shevy>
senoralastair you access info from an object by calling a method usually; the method will return however things are stored, which typically means that internally a @instance_variable is used
