Any suggestions for how to partially match a key in a hash?
<zenspider>
JosephRuby: partially?
<JosephRuby>
e[:adverb] = adverbs.find{|v| adverb =~ /#{v[0]}?/i}[adverb] is what I am using I want 'angr' to match key 'angry' in adverbs
<zenspider>
my first suggestion would be to use the proper data structure for the job... but your question is vague enough that I can't go further than that
<zenspider>
adverbs is a hash?
<JosephRuby>
yes adverbs is a hash adverb is a string
<zenspider>
then use |k,v|
<zenspider>
and yeah. proper data structure. if you want to stem words, this is a solved problem. google "ruby english word stemmer"
<shevy>
JosephRuby you can also get Abbrev.abbrev or whatever it was called to get a list of sub-strings for 'angry'
<JosephRuby>
ty both
<zenspider>
that will bloat out the hash with a bunch of keys for a task he doesn't need

<Defusal>
Hmm
<Defusal>
why wouldn't i be able to require files in sub directories of a gem?
<rue>
Because either you're using the wrong path or your load path doesn't include the correct directory
<Defusal>
rue, how can it be the load path if i can require the gem name?
<rue>
I don't know what gem refers to in this case. An actual gem that you've gem installed?
<Defusal>
yes
<Defusal>
otherwise it would just behave like normal ruby files
<Defusal>
i've never needed to require a custom path of a gem that wasnt documented before, and it doesnt seem to work, so im wondering why
<rue>
What's the lib dir look like, then?
<Defusal>
like what im requiring?
<Defusal>
im testing 'steam-condenser/steam/steam_player'
<Defusal>
path being lib/steam/steam_player
<rue>
Your tests should have nothing to do with this
<Defusal>
i don't understand why it doesn't work
<Defusal>
i mean im testing requiring that path...
<rue>
If your gem, unpacked, has a lib/steam/steam_player.rb, then your require is "steam/steam_player"
<Defusal>
only from inside the gem?
<rue>
Your gem will assume that the lib/ dir is in the load path
<Defusal>
you're not understanding
<rue>
No, I really dunno wtf you're doing
<Defusal>
i want to require files that are part of a gem that is installed
<shevy>
now you made rue angry and mad and he will have to kill kittens :(
<Defusal>
i've done it before for gems that have such paths documented, such as active_support/core_ext
<Defusal>
so i am asking why it does not work for another gem
<rue>
Because you're using the wrong path
<rue>
I don't know what the right path is, but since it's not working, you're using the wrong one.
<Defusal>
sigh
<rue>
When a gem is installed, everything in its lib/ is copied to your libdir
<Defusal>
then rubygems is making up its own path internally
<Defusal>
clearly it does not work..
<rue>
So, for example, if the gem has lib/foo/bar.rb, then your libdir will have foo/bar.rb, which you can require as "foo/bar"
<rue>
This is why there's a convention that for a gem named xyz, there's a lib/xyz.rb and a lib/xyz/ (as necessary)
<Defusal>
rue
<Defusal>
how can requiring "foo/bar" know that foo/bar is in gem X
<Defusal>
you are not making sense
<rue>
It doesn't. You have a library path
<apeiros_>
Defusal: you not being able to make sense of it != rue not making sense.
<Defusal>
ok, so the only way to require a gems subfiles is to manually add the gems lib path to your app and then require it
<rue>
Defusal: If you print out your $LOAD_PATH, you'll see the directories that require looks at
<apeiros_>
no
<Defusal>
that seems rather strange, but i will take your word for it
<Defusal>
rue, obviously
<rue>
Defusal: Do you see a directory for the gem that you want to use?
<apeiros_>
rue: that won't show him what rubygems searches additionally, though
<Defusal>
rue, yes, in Ruby193/lib/ruby/gems/1.9.1/gems/
<shevy>
rubygems secretly searches through your pockets as well
<rue>
apeiros_: No? I don't remember, I thought it added everything
saLOUt [saLOUt!~rriemann@91-65-223-29-dynip.superkabel.de] has joined #ruby-lang
<rue>
Defusal: So for example for Rack, I've "/Users/ruerue/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.5/lib"
<apeiros_>
rue: only after (technically during) the require
<Defusal>
rue, yes, and?
<rue>
apeiros_: Ah yes, that's true
frangiz [frangiz!~frangiz@user26.77-105-206.netatonce.net] has joined #ruby-lang
<apeiros_>
Defusal: requirements: rubygems is loaded (usually always the case with ruby 1.9), the gem is installed for that ruby (rvm? using the right ruby?), the path you require from the gem is part of the gem's lib-dir (see that gem's gemspec)
<rue>
Defusal: If the Rack gem has a lib/rack/foobar.rb, then, because of above, I can now require "rack/foobar"
<apeiros_>
your active_support/core_ext example: the gem lists GEM/lib as its lib dir. there is a file GEM/lib/active_support/core_ext.rb, hence require 'active_support/core_ext' will work
<Defusal>
well
<apeiros_>
after requiring anything from the active_support gem, GEM/lib will be in $LOAD_PATH (is used GEM as a variable for wherever the gem is installed on your system)
<Defusal>
that clears up absolutely nothing, because i already knew all of that, and it still does not work
<apeiros_>
if you can't require, any of the requirements I listed is not met.
<Defusal>
let me look at the gemspec, maybe its remapping the lib path? in which case i didnt know it could do that
<apeiros_>
also, can't require = when you do require 'foo' you get a "LoadError: cannot load such file -- foo", yes? (make sure the 'foo' part matches)
<apeiros_>
yes, give me the name of the gem and give me the require line that fails.
<shevy>
HURRY DEFUSAL!
<Defusal>
im trying to require "steam-condenser/steam/steam_player"
<rue>
Why?
<Defusal>
[15:27:29] <Defusal> i just cant require it on here, because its missing a dependency [15:27:38] <Defusal> so it fails to load the extension [15:27:46] <Defusal> so i just want to load some files to use
<rue>
You should be requiring "steam/steam_player"
<Defusal>
i already asked you how it can know that that path belongs to that gem
<Defusal>
theres is no way without manually adding it to the load path, which would defeat the purpose of this
<Defusal>
but as i said, if manual is the only way, ill just suck it up and append it to the load path
<Defusal>
all i want to know is why
<Defusal>
i've wasted too much time on this pathetic issue already, ill just assume you're right and it cannot be done, even though active_support/core_ext works, which is confusing as hell, and ill manually append it to $LOAD_PATH
<apeiros_>
Defusal: how it can now? easy, it searches them all.
<apeiros_>

imperator [imperator!~Daniel@63-225-247-192.hlrn.qwest.net] has joined #ruby-lang
<Defusal>
apeiros_, then how does it know to use that gems files and not another one that has a steam/steam_player file/
<apeiros_>
Defusal: take an educated guess…
<Defusal>
you could have tons of gems installed on the system
<Defusal>
that seems really odd
<apeiros_>
no, it seems really inefficient
<Defusal>
that too of course
<Defusal>
but wow
<Defusal>
i consider that quite a flaw in rubygems, i cant believe i never knew about it
<apeiros_>
afaik it'll search through all gems (newest version)
<apeiros_>
if you've got multiple gems with the same paths in their lib dir, you're fucked. simple as that.
<apeiros_>
that's the same with $LOAD_PATH too.
<apeiros_>
first one wins.
<Defusal>
yeah
<Defusal>
pretty bad
<rue>
That's what the namespacing is for

no.

^^^ is that normal?
<apeiros_>
"`require': 126: The specified module could not be found." is not an exception by core-ruby, so what generates it?
<Defusal>
apeiros_, really
<Defusal>
apeiros_, then i have no clue, no such string exists in this gem

perhaps its the broken zlib installation

lol
<manveru>
why 256?
<shevy>
you are turning japanese ruby coder
<tylergillies>
well it doesn't _have_ to be one byte
<shevy>
how about one byte and a half
<apeiros>
manveru: 1 byte is in any sane system 256 values
<manveru>
oh, didn't read the byte thingy
<apeiros>
shevy thinks out of the byte…
<rippa>
about 30000 words should be enough
<rippa>
so, 2 bytes
<shevy>
that's a lot of words
<manveru>
some kinda huffmann encoding?
<rippa>
though it's not suitable for text encoding, ofc
<rippa>
because word forms
<apeiros>
rippa: my words file has 235'886 lines
<apeiros>
so we'd be at 3 bytes.
<tylergillies>
working on a binary encoding. if the word matches word in dictionary it gets encoded as two bytes if not then it gets encoded as however many bytes it has characters
<rippa>
apeiros: that's some uncommon words
<apeiros>
or 18bits
<manveru>
tylergillies: you know gzip?
<apeiros>
rippa: I don't know what you consider *common* words

it's just the result of $ wc /usr/share/dict/words
