Is there a link with hashtable ?

tLabel itself doesn't tell me anything. I guess that's how the tokenizer calls it…
<apeiros>
moin ljarvis
<bog>
apeiros, what is the "tokenizer" ?
<ljarvis>
bog: what ruby version are you using? `ruby --version`
IanVorn has joined #ruby
<apeiros>
bog: something irrelevant to your question. it's part of how code is usually evaluated. the first step is tokenizing the blob of text.
<bog>
ljarvis, 2.1.6
<ljarvis>
bog: ok, please paste your code on gist.github.com

tLabel is used for 1.9 style hash keys in the lexer (I think)
IanVorn has joined #ruby
<ljarvis>
i should really start just calling them hashes and not 1.9 style hases
<ljarvis>
hashes*
<apeiros>
ljarvis: that's what I'd assume too. but I don't want to guess, hence waiting for actual code by bog.

bog: it's not var
<apeiros>
it's a value
zel is now known as drzel
<apeiros>
like "var" is a literal string, :var is a literal symbol
IanVorn has joined #ruby
<bog>
is that a kind of pointer ?
<apeiros>
no
<apeiros>
it's kind of a number combined with a string
<apeiros>
for the programmer, the string aspect of it is the important part, for the machine it's the number which is important
<bog>
humm.. I don't really understand what is a symbol
<ljarvis>
bog: do you know any other programming languages?
<apeiros>
at this point, you can just think about it as a string (just with a different class than String). in most cases that's how it behaves.
<bog>
ljarvis, I know python, java, c and c++

ohh ? Symbols are not variables ?
<apeiros>
you can't assign a value to a symbol. i.e., `:symbol = "value"` is NOT valid. because symbols are not variables, they're values.
<bog>
Symbol are object ?
<apeiros>
yes. as I said from the start :-p

why is it when i quit terminal, and reopen it my ruby version is back to 2.0.0 but when before it said 2.2.2
<irctc239>
i followed Radars guide
<apeiros>
bog: the main difference is that a symbol with the same value will always be an identical object.
<bog>
apeiros, if plain: "value"` is an alternative way to write `:plain => "value"`{, and if plain: is a symbol, so `:plain => "value"` is also a symbol since it is juste a rewriting, no ?

So I found rescue-scheduler but it's in default reading the yaml file.

Hi! Say I have allocated some memory with ALLOC_N(). Later on I have a conditional rb_raise() in my code. If the check doesn't pass I xfree() the allocated memory. My question is should I worry about the allocated memory if the rb_raise() conditional succeeds and I actually raise an exception

<zenspider>
benlieb: what you're asking for is a bad design smell
mary5030 has quit [Ping timeout: 256 seconds]
<zenspider>
you could refactor to an error_handler method that yields the body
<benlieb>
Oh, I didn't know that you could leave out the begin. There is a lot of redundancy that does rescue Faraday::Error => error handle_ned_error(error) end

cndiv has joined #ruby

then it'd be handle_errors do ... end in each method
<dfockler>
^ I've done this before, and it works
<benlieb>
zenspider: that's an interesting idea...
<zenspider>
of course, if every method in here is doing the same thing, it's still a design smell
<zenspider>
the caller should probably be handling errors
<zenspider>
and it is non-idiomatic in ruby to start methods with get_
swgillespie has quit [Quit: My MacBook Pro has gone to sleep. ZZZzzz…]
<benlieb>
not every method, but it's basically a class that talks to an API, so a lot of the methods can throw a Faraday (http) error

well... it looks like every one. the ones that don't call methods that do
<zenspider>
"NED.instance." is totally redundant since self is already the singleton
<zenspider>
singleton is ALSO a bad design smell

you really want all API access to bottleneck through a single object/thread?

handling exceptions is one thing, messaging (based) on exceptions is yet another one // as for the http codes it would be better to place all those messages in a hash code => message

endash has joined #ruby

benlieb: for now I'd go with my handle_errors suggestion above

The system is a rails API that basically sits in front of a more low level java API
<benlieb>
The rails app handles auth and sessions etc, and also makes messaging more "human". Internally we hit the java api ourselves, but we expose only the rails app that other's can hit
