pms Application documentation (v0.0.5)


This documentation refers to pms version 0.0.5


Provides a simple searching facility for (nearly) arbitrary input. It allows searching by Strings (exact match) or Regexps (full control, but slower). Boolean operators AND, OR, and NOT are supported, as well as proximity operators NEAR (with configurable distance) and ADJACENT (taking order into account). You can chain operators and also group them into sub-queries.

Inspiration came from a discussion on ruby-talk, starting with message ruby-talk:322014, but PMS has a more document-centric attitude (everything that input#each yields is considered a document of its own).


require 'pms/ext'

text = <<EOT
Hello world, how are you today? I said "Hello"
to the other guy but he would not answer although
all the world could hear me.

search ='hello').near('world', 3)

p search.results
#=> [0]

p search.results_with_positions
#=> {0=>[0, 8]}

p search.matches
#=> ["Hello world, how are you today? I said \"Hello\"\n"]

You can find more examples in the spec/ directory.
