Poshy

The basic idea behind this gem is to be able to detect if a non nested hash matches a query string. The query syntax is extremely simple but has some limitations.

Example

query = '(name=john&age>20)|(name!=john&age<40)'
input = { 'name' => 'john', 'age' => 30 }

PoshyMatcher.match?(query, input) # true

Poshy Matcher is just a minimal interface to a Treetop based Parser. Check the grammar for more details.

To run the tests:

$ rake

Limitations

This is just a proof of concept of something needed for a personal project, so I just spent a few hours working on this.

Right now is not possible to compare floating point numbers.
