Syntax example

This is an example of the supported syntax.

import 'tools'

v = v + 1 + ((2 - 3) * 4) / p.g(a)
# a method
def greeting(string name, string suffix) -> string:
    return 'hello ' + name + suffix
end
/*
 * A Hello class
 */
class Hello:
    sql.select sqlStringVar:
        column1, column2, column3
        from table1, table2, table3
        where table1.id = table2.table1_id and table3.state = {'active'}
    end
    struct Address:
        string name 20
        integer number 3
    end
    struct Person:
        string name 10
        float height 1,2
        Address address
    end
    def foo():
        if (a.r > 2 and 1 < 3 or d >= 2 or (9 <= 4 and s == 2)) != 4:
            a = 'hello' + 'world'
            if true or false:
                g = g.f + 0
                insert> g
                continue
            else
                c = [2.3, 54]
                sql.update c
                continue
            end
            return
        end
    end
end
a = i.u
for g in h.p:
    a = 9
    f(a, 4)
    break
end
while a < 10:
    a = a + 1
end
sql.delete a
c(8,9)
match a:
    case 1:
        if a > 1:
            return
        end
    end
    case 2:
        break
    end
    default:
        return
    end
end

Quick start

You can parse an ani piece of code

// file.ani => a = 1 + (2 - 3)
final AniParser parser = new AniFile(input).parse(); 

If the parsed content has grammar errors it will throw an exception when parsing AniParser.file(). To avoid this situation you can scan for errors before you parse

// file.ani => a = .
final List<ParseError> errors = new AniFile(input).errors();

$ ./mvnw clean package -Pqulice

It's required to set up the ANTLR plugin for intellij following these instructions. This plugin will help when working on the grammar.
