Lexical Analyzer and Parser for a programming language named Galaxy based on a LL1 grammar which you can find Here
Here are the rules for this programming language:
- Integer:
protostar x := 15 %
A protostar is a star in it's early stages.
- Float:
star x := 15.5 %
- String:
planet x := ' Hello World ' %
- Character: stating a character would be like this:
asteroid x := 'Hi' %
Note that asteroid is a minor planet.
- Array: we can define a multi-dimensional array of objects with "cluster DataType ArrayName , Size , SizeOfEachElement %":
cluster protostar x , 10 , 5 %
Note that Star Cluster is a big group of stars.
- Loop structure:
ring ( condition )
statement1 %
statement2 %
...
- Conditional structure:
nebula ( condition )
statement1 %
statement2 %
...
A Nebula is an interstellar cloud of dust and gases where stars are born, so you can define conditions for the stars you want to create!
