Btw, I am running Ruby 2.1.2.
Thanks

Hi,
I am facing in issue when trying to deploy my app to heroku with the summarize gem.
Heroku returns the following error
remote: Fetching dependency metadata from https://rubygems.org
remote: Could not find summarize-1.0.4 in any of the sources.

when I try specifying the github repository in my gemfile before pushing it, I get:
remote: Fetching https://github.com/ssoper/summarize.git
remote: There was a LoadError while loading summarize.gemspec:
remote: cannot load such file -- summarize/summarize from
remote: /tmp/build_4223d0ae60599e1f77e9caca2476e8b3/vendor/bundle/ruby/2.2.0/bundler/gems/summarize-a80c110fa4fe/summarize.gemspec:2:in
remote: `

Please can somebody help me out?
Thank you.

EDIT:
Turns out I was making a mistake in specifying the verison on Heroku. I was referring to version 1.0.4 which is not out on rubygems (it refers to v1.0.3)

More of a feature request rather than a bug.. But would be nice to get access to --about (since --keywords is deprecated), which simply returns the top keywords/topics for the input doc!

ex:

ots ig1 --about

I have all the necessary packages installed for summarize, the gem is installed via my gemfile in my rails 3 application, and in development it seems to be working correctly however since deploying to production I am now getting an "undefined method 'summarize'"

Error message : gems/summarize-1.0.3/lib/summarize.rb:100:in `summarize': Cannot load dictionary file (RuntimeError)

Hello,

After installing the gem and trying to run a test through irb like:

"My string".summarize(:ratio => 25)

I always get the following error:

NoMethodError: undefined method `summarize' for "your_string":String

It looks like although the gem is installed it is not being recognized. I doubled check I have glib2 and libxml2 installed.

Any idea on how to solve this?
Thanks!

Sean:
First, thanks for your work on this. It's a lifesaver. But of course no good deed goes unpunished.

I'm having trouble opening a custom dictionary file. The context is maybe unusual -- I'm in the middle of a block that opens a persistent httpd connection, like this (highly simplified):
httpcon = Net::HTTP.new(server_uri.host, server_uri.port)

fetch many files and summarize them

httpcon.start do |http|

...
## fetch a file
contents, topics = filecontents.summarize( :topics => true, :dictionary => '/some/random/dicfile')
...
end

I get something in the depths of http.rb complaining that it can't open the file, apparently thinking that it should be doing so over the http connection rather than reading it off local disk.

Any ideas? For now, I'm mangling the local (gem) copy of en.xml, but that's not good ;).
