=> #<LinkParser::Dictionary:0x007f9a5b117220>

sent = dict.parse( "People use Ruby for all kinds of nifty things." )
=> #<LinkParser::Sentence:0x1fe69761a146 "LEFT-WALL people.p use.v Ruby.f
    for.p all.a kinds.n of   nifty.a things.n . RIGHT-WALL"/15
    linkages/0 nulls>

sent.subject
=> "people"

sent.verb
=> "use"

sent.object

puts sent.diagram( max_width: 200 )

Installation

First, download and install the latest version of the link-grammar library from Abiword's site.

Then install the gem:

gem install linkparser

You may need to specify the path to the link-grammar library if you installed it somewhere that your linker doesn't look by default:

gem install linkparser -- --with-link-grammar=/usr/local

Contributing

You can check out the current development source with Mercurial, or if you prefer Git, via its Github mirror.

After checking out the source, run:

$ rake newb

This task will install any missing dependencies, run the tests/specs, and generate the API documentation.
