Small example of a language and its grammar

Language

Here are sample of our language.

ON LIGHT

      OPEN DOOR

      OFF LIGHT AND TV

      CLOSE WINDOW

Grammar

Here is a version of its grammar

We have to separate command into two groups because the objects are different for different commands.

G = V1 OBJ1  |  V2 OBJ2

      V1 = ON | OFF

      OBJ1 = LIGHT | LIGHT AND TV

      V2 = OPEN | CLOSE

      OBJ2 = DOOR | WINDOW

This grammar covers our sample language. If you want to make it a bit more flexible, we should consider how to decompose "LIGHT AND TV" into smaller parts which can be reassemble into different sentences.
