Clause Parser

A clause is some text interspersed with placeholders. _placeholders, which will get their values when the clause is created.

Tags are specified with the following syntax:

[<name>: <source> { <field-path> <operator> <value> }]

The complete grammar can be found in grammar.pegjs

Quick Sample

    [temp: city{temperature > 0}]°[unit: temperatureUnit{unit != ""}]
