Galaxy-Compiler

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!

• Comment:
  • Single-line comment can be followed by ||:

   || a comment
  

  • Multi-line comment block:

   |.
   comment1
   comment2
   ...
   .|
  

• Operators: This is very simple: Expression OPERATOR Expression. For example:

x + y 
x // y

Each Operator definition can be found in Delimiters and Operators
